Description Mikhail Gusarov 2007-09-10 23:43:37 UTC

I'm encountering screen corruption in 1920x1200 and 1600x1200 modes after just running xrandr without arguments. Screenshot, xorg.conf and logs are attached.

Changing resolution (using xrandr) to smaller one and back to the higher cures the problem.

Hardware: Radeon 9600 (mobility version), VGA output with Dell2407WFP monitor.

Software: server 7.2.0, ati 6.7.192.

Not sure I've selected proper component, but I don't have another videocard handy to say it is driver's or RandR bug. Please reassign if I'm wrong.

does disabling dynamic clocks help?  Also, you don't need multiple screen and device sections in your config.  you can remove those.

Comment 6 Mikhail Gusarov 2007-09-13 23:44:44 UTC

Disabling dynamic clocks does not help :(

Comment 7 Mikhail Gusarov 2007-09-15 08:48:35 UTC

I have removed second "Screen" and "Device" sections from config and problem disappeared.

However, I'm afraid the problem is still here, just not being triggere, so I'm keeping this bug open in case you ask me to test something.

Comment 8 Alex Deucher 2007-09-18 17:14:02 UTC

can you try again with the latest code from ati git master?

Comment 9 Mikhail Gusarov 2007-09-29 07:01:39 UTC

What components should I build and test? Is ati driver will be enough?

Comment 10 Alex Deucher 2007-09-29 10:04:15 UTC

yes.  Try the latest ati driver from git.

Comment 11 Mikhail Gusarov 2007-11-04 08:15:00 UTC

As I expected, bug manifested itself again, in less obvious way: after couple of screen resolution changes, text rendering in Qt-based applicaitons breaks (resulting in more-or-less same garbage as can be seen in first attachment in bug). Other xft-based apps are not affected.

I'm going to test git master as soon as find time to do this.

Comment 12 Alex Deucher 2007-12-11 09:16:26 UTC

Please try again with ati git master and let me know if that fixes it.

Comment 13 Mikhail Gusarov 2007-12-11 10:11:49 UTC

Does not manifest itself now, after couple of updates of Debian package.
