Replace krfb with vino in kde4

2010-03-03T01:00:00.001-08:00

I use kde4 on my server box due to some audio problem with gnome. In gnome I am not getting any audio. I broke my head for long time, installing, removing and configuring pulse audio to no avail.

So, I moved to kde4 and it was easy enough and my audio started working without pulse. I do not want pulse as there is no ac3 pass thru support which I need for home teather.

I used to run vino on gnome to remotely access my comp. KDE has krfb, so I used to do auto start it when I login.

Problem with krfb is that it hogs the system when you are remotely accessing, cpu spikes to 100% and system kind of becomes unusable with lot lag.

I loved vino so I did the following and now I can use vino on KDE.

1. Stop krfb

2. Remove krfb from startup.

3. open konsole.

4. type vino-preferences

5. Configure vino and you are all set.

I am assuming you have vino installed, else install it from your repository.

Now no more lag, and no more cpu spike when using remote desktop :-)

copper mod studio xps m1330 to lower temperature...

2010-01-29T22:40:00.001-08:00

My studio xps like other's was running hot... around 64c (GPU) and 56c (CPU)... It used to get very hot esp doing some kind of intense activity like watching hulu or playing games... GPU would shoot up to 74 to 80c and CPU around 84c...

So, I searched on the net with old friend google and came across this thread... and ordered some stuff from net... total cost came around 15$ including shipping.

Once I got the items, I opened the case and found it is not matching to what was given in the pictures.... seems the instructions were for xps and not for studio xps... but still I continued and found the gpu and cpu and other things in similar fashion... Also you can search on the net... probably you will stumble across this post....

I removed the thermal pad, cut the copper sheet... tip on cutting copper. use a wire cutter or some sharp thing to first make a small groove and then use the hacksaw...

I used arctic silver 5... there are other better compounds but would make a bigger hole in your pocket... so choose accordingly...

I replaced the thermal compound... added the copper and applied thermal on both side of it, put it on gpu and closed the lid... and started my comp...

and to my wonder, idle temperature went down to 45c (CPU) and 52c(GPU)... wow quite an amazing job... I must say... Under full load temperatures goes around 68c (GPU) and 70c (CPU)...

also did I say I used linux to test everything... well I used nvidia app and plasma applet for temperature...

Have to check it in windows too but too lazy to go in there as I use linux as my primary OS .. :-)...

Now, the laptop is much cooler or let say comparitvely cooler... the design flaw of dell is pretty huge I must say... laptop should have side heat sink so that air can go from the side and does not get blocked by the lid....

I would definitely recommended this mod if you want to bring down the temperature...

Studio XPS M1330 best for linux

2010-01-25T16:41:00.001-08:00

So far I have had 5 to 6 laptops on which I have had linux installed.

1. Acer aspire - some old model during 2006 year days, graphics card from SIS, had lots and lots of trouble in getting things working with ubuntu. Early days of ubuntu I think might be responsible. But from that time I decided I would never buy a product which has SIS. No support for linux.

2. Dell Inspiron - ATI graphics, in 2007 early months, had some problems with ATI as support for linux was nascent in those days. ATI support for latest graphics card for linux is crapy so if you are planning to buy a newer laptop with ATI then good luck with linux.

3. Lenovo T61 - good support, again ATI support was not good, with 3d acceleration etc it was not comparable to current laptop. But overall pretty decent, things worked out of the box.

4. Toshiba Protege M500 - Pretty old laptop, so no problem in getting linux work. Only problem being with mic for skype and audio muted if muted in windows and if logged in to linux. Jaunty or may be Heron fixed the issue. Still use it as it is my company laptop ;-).

5. Asus M51Ta- Night mare... no fault of asus though, ATI again, dual graphics card, it sucked big time in support. Would have preferred one single card instead of two.

6. Dell Studio XPS - boy does it work, every I mean everything, webcam, wireless, graphics card (Dual), bluetooth, mic, hdmi, even audio through hdmi... everything works right out of the box, drivers for nvidia installed but for graphics and drivers for broadcom wireless .... and it is like a breeze... has slight heating issues, would be doing copper mod shortly to reduce the heat, waiting for copper, thermal compound to be delivered... next upgrade on it would be an SSD drive.... but would wait for another 6 months for prices to go down....

Studio XPS M1330 highly recommended if you want every thing... I mean EVERYTHING to work out of the box on your computer using linux....

GO NVIDIA... ATI ... learn something from them...

Reduce Memory Usage Ubuntu/Kubuntu

2010-01-21T16:40:00.001-08:00

So, I have one of my machine which has 1GB RAM... I know it is good enough for the work I do, but still being that fanatic of getting more RAM for my work, I did the following changes to increase the free RAM.

1. Disable unnecessary services. There are two places this needs to be done as some services use upstart and other are still using init.

2. Disable upstart processes. Browse to /etc/init and rename the files ending .conf to something else and that service would not start. Remember not all services should be disabled.

This is the screen shot of the services I have disabled. I have appended a ".no" to the file name.

3. Next is to install the software sysv-rc-conf.

Run it as root in a terminal and remove the check marks for those services which you do not need.

I generally remove bluetooth, blrtty, portmap, samba. Do not remove

bluetooth - if you are going to use bluetooth on your computer.

blrtty - if you are going to use the assistive technology features of the OS.

portmap - if you have done any port mapping on the computer.

samba - if you are going to share using samba with some windows computer.

After doing this, my memory consumption in KDE4 is 198 MB... went down from some 300MB odd which was earlier. Suprisingly, KDE4 is taking lot less memory compared to gnome. May be the new GDM is taking lot of memory.

I keep shuttling between KDE and Gnome from time to time, but off late have been using KDE4 for its widgets and cool features.

Change My RAID1 filesystem to Reiserfs

2010-01-01T21:38:00.001-08:00

Well... I was not sure what was in my head when I first configured my raid1 some one year back... I kep one raid partition as ntfs... with the support of ntfs not so great and file system itself having issues with fragmentation, I think it was a very bad move...

Anyway... I corrected it today. I remove the ntfs and replaced with reiserfs... but not without hiccups..

here is the order in which I proceeded, posting for others if they also do such thing in future..

1. take back up of your data. do not do it on another ntfs, if possible get other linux drive and do it. And BIG NO to FAT32, it will not take files bigger than 4 GB.

2. edit your /etc/fstab and comment out the raid, reboot.

I did this step as it kept giving me error resource/device busy, please try again. Umount -f and mdadm --stop none of them were working.

3. After reboot, just type the following command.

mkfs.reiserfs /dev/mdxxx, replace xxx with the raid number you have.

There is no need to stop mdadm as it is not required.

4. Edit your /etc/fstab, uncomment the raid line. And this is very important, change the file system to match your file system.

Remember, previous step is very important.

5. Mount the file system again and

6. Copy your data again.

Installing Tomcat On 64 bit Linux

2009-11-19T20:41:00.000-08:00

So am doing one project where I have to work on exposing spring bean as soap webservice, json, restful webservice and as ejb.

As tomcat being easy and free server to host, I went down to install it and run my project using tomcat.

I will put spring beans and other stuff later. I would start with the installation of the tomcat software on my ubuntu sorry kubuntu linux 64bit.

1. Get the tomcat binaries from tomcat download site.

2. Get the 64bit jdk from sun's java site. make sure you are downloading 64 bit version of the jdk. For tomcat you just need jre, but I am using jdk (it contains jre), the reason being I would be using the same to configure eclipse to use this jdk.

3. Make the jdk-6u17-linux-x64.bin executable. Depending on the release, the file name would be different.

chmod 755 jdk-6u17-linux-x64.bin
./jdk-6u17-linux-x64.bin

4. This will create the jdk folder and the required jar files.

5. Move the jdk folder to /opt folder. I prefer to do this as I keep all my installed software in /opt.

sudo mv jdk1.6.0_17 /opt

6. Now similarly extract the tomcat folder and put it in the /opt directory.

7. Now create a group named tomcat.

sudo groupadd tomcat

8. Now create a user named tomcat

sudo useradd -g tomcat -s /usr/sbin/nologin -m -d /home/tomcat tomcat

note that this user cannot login into a a shell, this is for security reasons. So no one can hack into and login into the system using tomcat id.

9. Now change the ownership of tomcat directory in /opt to tomcat.

sudo chown tomcat:tomcat -R tomcat.6.0.20

10. Now add yourself to the tomcat group, (required if you want to put the files in tomcat directory by copying, pasting)

usermod -G -a tomcat username

11. Now log out and login.

12. Browse to tomcat/bin directory. Open the setclasspath.sh file in your favorite text editor.

add variable following variables just under CLASSPATH = line.

JAVA_HOME=/opt/jdk1.6.0_17
JRE_HOME=${JAVA_HOME}/jre

Save the file.

13. Now run the command ./startup.sh. Your tomcat should be up and running. If not refer to the logs file under tomcat/logs directory for debugging.

to check if tomcat is up and running, open firefox or your favorite browser and go to url. http://localhost:8080/.

And you are all set now...

Hope this helps...

Silence GTK Sound In KDE4

2009-11-17T21:33:00.000-08:00

I switched to kde4 as like its sleek modern looking UI. However, I was not able to move or find alternate for firefox.

Every now and then firefox alert used to give this annoying bell like sound, it is really frustrating. I found a solution for this annoyance.

Open up ~/.gtkrc or ~/.gtkrc-kde4 in your favourite editor. Add the following two lines to the file.

gtk-enable-event-sounds= 0
gtk-error-bell=0

Now log out and login. And you are all set.. the annoying sound is gone.

I have one of this 780g chipset htpc with ubuntu running on it. the issue I faced with latest ati driver was that resolution of the system used to go to 1080p every time I rebooted my machine. My computer is connected to a 720p TV so this made the reading of content a tad too difficult from the sofa. So I searched on the net for some time and found this awesome thread which saved my eyes the pain of squeaking...

To summarise, you need to do the following...

Click System --> Perference --> Display... click "NO" ... now change the resolution to what you would like in my case 720p and that's it you are all set...

Force Skype to use qt4 theme

2009-06-02T09:01:00.000-07:00

I use skype for chatting and online talk with my friends and family back home. However, every time I use skype I hate that even though it is a qt4 app (now), it still does not honour my kde settings.

So, I did some research (read googling) and found out the following way would easily solve the problem.

When starting skype, just use the switch "--disable-cleanlook" and it should pick up the theme which is selected in the kde4 settings. Or if you want to use a particular style then you can pass the theme name as "--style .

skype --disable-cleanlooks

Hope it helps some one... enjoi...

At last desktop effects on my asus m51ta-x2... yoo... hoo....

2009-05-21T16:39:00.000-07:00

Seems the latest git for ati open source driver has the dri (direct rendering infrastructure) working. So, after installing the drivers from the source I was able to enabled desktop effects in my kde4. Yup sweetness of success atlast... so here are the steps to enable it...

Open your favorite command line too (konsole, terminal, xterm etc)

sudo apt-get install build-essential autoconf automake libtool pkg-config git-core

sudo apt-get install libdrm-dev x11proto-gl-dev mesa-common-dev xutils-dev x11proto-xf86dri-dev x11proto-fonts-dev x11proto-randr-dev x11proto-video-dev x11proto-xext-dev x11proto-xinerama-dev x11proto-render-dev xserver-xorg-dev

git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-ati

cd xf86-video-ati

./autogen.sh --prefix=/usr --enable-dri

make

sudo make install

Now reboot your computer. I thought restarting kdm should have worked, but it seems the driver files are not getting loaded.

Open your system settings and go to desktop effects. Click enable, but before you press apply go to advanced and change the rendering to xrenderer. Now click apply and there you go.. linux eye kandy the way you want :-D....

some changes are done from the steps given here. All credit goes to the post in the link and to open source ati developers... hats off to you guys...

Atlast I have everything working on the new asus laptop... was challenge... but it seems the new jaunty release of favorite distro ubuntu has everything working except for sound.... so the following things are working out of the box...

1. boot without any acpi=off in the boot option.
2. wireless
3. lan
4. graphics card not sure which one is in use though, there is no 3d acceleration so no compiz as of now... this is due to merging of the latest open source ati drivers using radeonhd rather than using fglrx.
5. usb driver..
6. web cam... skyp is showing the web cam... some mic problem there but i have never got mic to work on first go.. :-)
7. bluetooth... the internal blueotth works without any issue.

not working
1. sound not working but was able to get it resolved by following instructions here..
2. no compiz...
3. very loud fan... and temperature remains in upper 60s..

so if you are having trouble with your asus with intrepid, then get hold of jaunty ... it is still in beta but it is quite matured by now... and stable too...

Sucess Atlast...

2009-03-27T14:42:00.000-07:00

Today the jaunty beta as released or may be yesterday... I downloaded the desktop cd... no go.. :-(... then downloaded the alternate cd...

2. after install, it will give blank screen and will not work...
3. reboot, go to recovery option and select fix x...
4. now, continue normal boot...
5. enjoi... your login screen will come up and you are all set...

Installing Linux On ASUS ...

2009-03-27T10:56:00.000-07:00

As I had expected based on the forums and other places I have read that there would be issue in installing linux on this baby...

The laptop looks pretty good, not stylish or as designer as the laptops like dell studio or hp hdx or lenovo ideapad... but for lesser dough you cannot get them with this config...

Anyways that is beside the point... come back to the moot point...

I tried installing alpha of jaunty, intrepid with acpi=off and noapic as per some thread but no go on that... would get stuck on some step or the other on booting itself... never came to see gdm login... so thought would try fedora instead... fedora 10.1 installed without any issue with acpi=off... but then there were some update and everything went bonkers... so now I am stuck with vista... I wanted vista to play games...

now I am waiting for the new version of jaunty to come may be beta and I will give another try to it to see if it works... if it works then custom compile the kernel to get acpi on and then if there are any other updates then I will keep updating this blog...

I am waiting for

2009-03-26T15:24:00.000-07:00

Make Openoffice3 default in ubuntu removing Openoffice2.4

2008-10-23T11:57:00.000-07:00

I am one of those who like to use latest version of the software which keeps me experimenting with new things every now and then.

So openoffice3 was released some time back and I wanted to make it as default for my kubuntu install. Here are the steps which I followed for the doing the same.

1. Download the .deb installer from open office.
2. Remove the previous version of openoffice. Open up synaptic, search for openoffice and then remove the one starting with openoffice. This will remove the existing 2.4 version from your computer.
3. Now, extract the tar file which you downloaded from openoffice.
4. Go to the DEBS folder and run the following command

sudo dpkg -i *.deb.

This will install everything... basically kitchen, sink everything.

5. You will still not get the menus in the office section of your applications. So, you go to desktop integration folder in the DEBS folder and again run the above command

sudo dpkg -i *.deb.

And you are all set. You may have to choose for open office for the file associated for open with for some time.

Till the backport repository has the openoffice3, this is the only way I can think of using openoffice3 as default.

Thanks to this post which helped me in setting up the things.

Error with Compiz Fusion Not Working

2008-03-13T11:57:00.000-07:00

Well, compiz is one of the coolest thing which linux has got. It was working flawlessly on my lenovo t60 and suddenly one fine day everything went bonkers... I started recieving these dreaded messages.

libGL error: drmMap of framebuffer failed (Invalid argument)
libGL error: reverting to (slow) indirect rendering
compiz (core) - Fatal: No GLXFBConfig for default depth, this isn't going to work.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0

when I used to run compiz --replace command. I searched the net for some time and then gave up. I thought what updates came through which screwed this up. I figured out I had only kde-core package and to upgrade to hardy I had to install kubuntu-desktop which inturn brings tons of other junk in xserver-xorg-video. So, I opened synaptic and remove all the chipset drivers. Do not remove fbdev else it will remove everything in xserver and your system will be in bonkers...

After doing that I just rebooted and yup.. my hunch was right... it was the other video drivers which were creating problem. Now, I am again running the compiz on my kde... and am loving it...

Boot Speed Ubuntu

2008-02-21T13:36:00.000-08:00

I tried different tweaks from here. However, my boot speed was still slow, it was taking 2 minutes or so to go to gdm login. So, I was thinking how to increase it further.

I did the concurrency=Shell as mentioned in the post above. Still the boot speed was slow. I saw that there was a culprit which used to print "Reading files for boot" for close to 45 seconds during the boot, before it proceeded further. I was sure that it was one of the services which was creating problem. I was not able to locate which one though... so I left it at that suffering with 2 minutes for booting up.

Then one fine day, I saw my cpu usage remaining 100%, so I checked top and saw apport running on top. Now, what was this apport... some googling and got to the information that it is error reporting service ... I thought I will disable it. I disabled it and also avahi daemon (I frankly do not know what purpose it serves). I connect to my serves manually as I know about them. So, disabled that too. And next boot no line of "Reading files for boot" and my boot time went from 2 minutes to 45 seconds... that was great!!!! Nice find... thought would publish it.

Concurrency=Shell error fix in Gutsy 7.10 Ubuntu

Well, I was trying to get my ubuntu gutsy to boot up with concurrency=shell... well for those of you who are not aware, when you boot up there are lot of init script which run. By default they run serially so if you have more than one processor only one thread runs during init i.e. boot. Concurrency=shell will create new shell and these scripts are run in parallel.

So, how you do it? Well change the /etc/init.d/rc and change concurrency=none to concurrency=shell.

Now, when you do it, there would be a problem with HAL. This happens as dbus and hal has same script order and hence creates a problem.

to fix this issue,

rename the file in /etc/rc2.d/S12hal to etc/rc2.d/S13hal
rename the file in /etc/rc3.d/S12hal to etc/rc2.d/S13hal

And that it... you are all set... reboot and you will definitely see change in the boot up time.. Give it a try.

If things do not workout then just change the concurrency=shell to concurrency=none.

High CPU AIGLX Watching Video Full Screen

I have T60 laptop with ATI X1400. I recently upgraded my driver to 7.12 latest release on 18-Jan-2008 from ATI. I noticed that when I was viewing videos in full screen the CPU was touching 100% or closer to that. I googled and found out that I had selected X11 as the output instead I selected xv or xvideo extension which is accelerated graphics and it worked. Now, no more 100% CPU when watching full screen videos. Credit goes to the original poster.. sorry I do not have the link with me.

Just in case you are facing the same problem then you can use this, hopefully it should help.
