some type of flickering interfernce while ingame

[Shadowmeph]

I am runninf 64 bit Ubuntu gutsy gibon on a freshly built Pc I installed the newest drivers for the video card and installed the 64 bit ps while I am ingame I get a flicker or a kind of pulse type of  interference I did a 

Code: [Select]

fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 3870
OpenGL version string: 2.1.7412 Releaseso I am sure the drivers are ok I also uninstalled the 64 bit and tryed the 32 bit ps and it was even worse. the pulsing looks allot like when you have a tape in a VCR and the tracking is off that is the best way for me to diskribe it. anyway I uninstlled the 32bit ps and reinstalled the 64bit because the interfence isn't as bad, I also have deul boot so I booted into windows and installed ps there and it has know problems at all so it has something to do with Linux and I really don't like windows and would prefer to play in Linux.
( confusing isn't it   ) can anyone help me with a fix?
I  read some where in one of the posts on here that someone had simular problems and changing to full screen corrected these problems so I tried that and received the following errors ( I hope this help narrows down the problem)
 Crystalspace.window.exrf86vm: unable to switch
Crystal space.canvas.glx2d:failed to open the x-windows
crystalspace,graphics3d.opengl:error opening graphics 2d context.

A description like "some type of" is hard to understand...

Is it more related to lighting, or more related to movement?

I experience some choppy movement, for example, which seems to be related to loading parts of the world, or to low resolution animations (the closer I get to a distant model, the smoother its animation stages get, and the smoother my movement is). Could be the "movement prediction" system getting confused.

I thank you for your reply it ended up being a well I will just copy paste it in here

It's a known issue when using ATI proprietary drivers and running Compiz. OpenGL stuff just flickers. You have to turn Compiz off, either by turning off Visual Effects in Appearance, or by typing:
Code:

metacity --replace

Then you can turn Compiz back on after you're done with the game. I feel so silly but very very happy at the same time

SO my Problem is solved now only if I knew how to put Solved on this post I hope this helps others like it did me

This resolved my flickering issue. Thanks for the post

I'm kinda new to linux, so I'm sorry if this sounds too noobish but I have to run "metacity --replace" every time before i start the game. There's gotta be a way to have this configured so it sticks. Does anyone know how to do that?

Thanks
