View Full Version : [ubuntu] ATI Drivers Flicker, Freeze and Overheat System

Hi all,

Recently switched to 8.10 -- So far so good.


Upon installing the ATI/AMD proprietary FLGLRX graphics driver I began to notice some detrimental effects.

1: When playing video or 3D applications (Google Earth, Screensavers etc) the image flickers violently -- Turning off Compiz (Normal effects) seems to resolve this issue.
2: My system regularly overheats.
3: My system (perhaps as a result of 2) crashes again, again and again during moments of heavy processing -- sometimes even just randomly.

Please, if you could offer any advice as to how I might solve this issues I would be ENORMOUSLY grateful. I do not plan to return to Vista; however, if these problems persist, I may have no choice.

ATI Radeon X1900
Intel Core2 @ 1.8ghz

Many thanks!

I'm not sure what the crashing/overheating issue is about, but your graphics card is supported by the open-source radeon driver. This driver works much better than fglrx especially for video (though it is a bit slower for 3d). It should be enabled automatically on installing ubuntu.

The open source drivers are pretty slow.

Scrolling down pages is jittery and makes everything other application (eg. music) stutter.

Also, whenever I try to play videos without the fglrx drivers, the player (Totem as well as VLC) just closes immediately.

Is Envy worth a shot?

Please, anybody who knows ANYTHING on the matter, post your suggestions. I'm desperate for advice.

ah yes the open source drivers need
Option "AccelMethod" "exa" added to the device section of your xorg.conf for video to work properly.
