Title:
[RV250] Regression: Screen corruptions on X + massive RAM- & Swap-
usage
Status in X.org XServer - ATI gfx chipset driver:
Invalid
Status in “xserver-xorg-video-ati” package in Ubuntu:
Fix Released
Bug description:
This is a regression, since in Ubuntu 10.10 (maverick) – apart from a
minor bug (see bug #539163) – I have no issues with my graphics
hardware and the performance is just incredible. In Ubuntu 11.04
(natty) I'm affected by heavy graphics corruptions in Gnome & in
addition RAM- and Swap-usage are far from normal. Since my hardware
doesn't support OpenGL 1.4 I'm not using Unity but the standard Gnome
desktop.
1. Graphics corruptions
1.1. with Compiz
When I use Compiz, after several minutes I see some minor corruptions in the
Gnome panel; normally in the beginning only one applet is affected (I'll attach
a screenshot) but after some time one applet after another gets corrupted.
1.2. with Metacity
When I use Metacity there's one corruption I can always reproduce by opening
Synaptic – when the password is requested, the background should be darkened.
Instead I see all kinds of corruptions. There are also other, less predictable,
corruptions. If it helps something I could add screenshots.
2. RAM- and Swap-usage
After one or two hours of work RAM-usage reaches around 40% (of 2GB) and from
this point on Swap (4 GB) gets filled up until it reaches 100% and the system
is unusable. When I use the same applications in Ubuntu 10.10 (maverick) around
30% of my RAM are in use and swap-usage stays under 10%. This applies to Compiz
– if it helps I can test RAM- and Swap-usage with Metacity aswell.
Workarounds
I. radeon-option "RenderAccel" "off"
This option reduces not just the performance but also the problems mentioned
above (but they are still present).
II. Forcing the card into PCI mode
This seems to solve the mentioned problems – at the expense of horrible
graphics performance.
III. radeon-option "EXAPixmaps" "off"
This option seems as the best workaround for me. The symptoms are still
present to a extenuated extent but performance is better than with workaround I
& II.
