71.111.116.69: /* Flickering video */

I was unable to execute "sudo sh ati-driver-installer-8-02-x86.x86_64.run --buildpkg Ubuntu/gutsy" because it says missing lib32. i had to install lib32 package which should have been mentioned in the documentation

== dkms? ==

I don't see any instructions for this newfangled dkms thing... Is it it done automatically? — [[User:SheeEttin|SheeEttin]] {[[User_talk:SheeEttin|T]]/[[Special:Contributions/SheeEttin|C]]} 09:13, 24 December 2007 (CST)

ANSWER: just install it before installing fglrx packages... they will invoke it. Nothing to do.

== APT/Aptitude ==
This guide use apt-get. Sometimes the apt-get and aptitude are interchangeable, but not always. Please don't edit this guide without knowing how use aptitude. For instance the commend "aptitude install -f" is not secure, can provoke damages (especially for "unstable" distributions).
In my opinion apt-get is better for this guide. --[[User:Subvertigo|Subvertigo]] 15:26, 13 January 2008 (CST)

== Problems with 3D acceleration ==
When I try to load an app. that lacks 3D acceleration like Celestia, Stellarium etc. my computer just logs off, and I have to log back in!? Please guide me.

==Found issues==

===Mipmapping in Compiz===
When mipmapping is enabled in compiz modules then they the contents don't show up. Disabling mipmapping fixes these problems. Ubunty 7.10 and ATI 8.1.

===Kibadock glitches===
Kibadock has a black background when acceleration is NOT enabled. When acceleration IS enabled it has some problems with some applications where windows aren't visible.

===Flickering video===
When videos are played in various players including embedded on websites with firefox then the video flickers with black.

* Has anyone found a solution to the flickering? I find it also occurs in 3d-enabled games. 11:56, 7 March 2008 (CST)

It seems to be tied to compiz. When I disable desktop effects (System --> Preferences --> Appearance --> Visual Effects --> Set to "None") the flickering on videos goes away. If I enable any degree of effects, even the lowest setting, the flickering reappears again. Very annoying. I'm running driver version 8.44.3 (don't recall the Catalyst version associated with this) on an X1950XT.

Update: Updated to driver version 8.47.3 and the same flickering on video continues as long as desktop effects are enabled.

==Comments==

===Infinite Loop===
Looks to me like 128.8.120.187, which seems to be a computer name Prospector in a lab of the University of Maryland Institute for Advanced Computer Studies, found my solution at http://ubuntuforums.org/showthread.php?t=663111&p=4109726, and put in a comment on the infinite loop possibility on 23:28, 21 February 2008, under the 4.1 3D desktop effects section. I couldn't find a fix for that anywhere, but finally figured it out myself, and let others know of the solution. It's just cool to see that someone thought my contribution was good enough for the Unofficial ATI Linux Driver Wiki's Ubuntu Gutsy Installation Guide, which I keep coming to over and over as I mess up my system again and again :D

So, whenever you get a solution to anything, put it online. It might be important.
