I have a Compiz flicker issue under certain circumstances.

Hi guys, first LQ question from me, lol

I use Debian/Lenny on a Pentium D with a ATI HD 4850, 2GB of ram.

I installed Compiz and just think it is the best thing I have ever seen... It makes using the four "desktops" incredibly easy.

Sometimes, like when I view a movie in VLC or Totem movie player, or in certain games [3d games], the screen containing the movie, game, etc will flicker very rapidly.

I have the little routine where I do a metacity --replace and then compiz --replace, but I'd rather not do this everytime I want to go watch my videos or play certain games/apps.

Many *thanks* to the person who can help me with this ;-)

What version of fglrx do you have? Newer ones are supposed to properly support redirected direct rendering which should prevent the flickering with opengl games or with video players using an opengl renderer. Having said that, I haven't actually tried any of these newer drivers.

brad@debcalculus:~$ aptitude search fglrx
i fglrx-driver - non-free AMD/ATI r5xx, r6xx, r7xx display
i A fglrx-glx - proprietary libGL for the non-free AMD/ATI
i fglrx-kernel-2.6.26-2-686 - ATI binary kernel module for Linux 2.6.26-
i fglrx-kernel-src - kernel module source for the non-free AMD/
i A fglrx-modules-2.6.26-2-486 - Display driver for AMD/ATI Radeon and Fire

Hopefully that helps. It seems to have one for my kernel. That would seem to say that it is the most up to date in the repository and the "right one" to have for Debian/lenny 5.0. I think...

Create a shortcut or try launching it from terminal using:

Code:

env XLIB_SKIP_ARGB_VISUALS=1 vlc

Hey thanks everybody for your suggestions so far.

VLC still flickers when ran with those arguments.

What is the output of 'dpkg -l | grep fglrx' ?

You are using fglrx 8.12, but RDR and proper textured video wasn't introduced till 9.3 or 9.4, as I recall. You'll need to update your drivers to fix that problem.

Adam> so, I installed fglrx through the terminal... That would mean I'd have to uninstall fglrx and compile it from source.... That didn't work given many different tutorials before. I finally discovered aptitude and found out the easy way to install it out of the repository [that I added I think; not sure if it was already in list].

OK, I did actually compile it from source: these are the commands I used:

su
aptitude update
aptitude install module-assistant fglrx-driver fglrx-kernel-src
module-assistant auto-install fglrx-kerenel-src
aticonfig --initial

I do want to *stress* I tried compiling from ATI, and from other sources so many times, all failed attempts. I had pretty much given up.. I read something about aptitude, and tried the above code, and it worked like a charm first time.

If there were a way to update it or install over without every uninstalling, I would consider doing that. Hehe, but before I do, I am going to backup my system and learn how to use my backup program from the terminal.
