since a similar bug had to to with aperture size mismatch, here's a kernekl excerpt: pci 0000:01:00.0: Boot video device Real Time Clock Driver v1.12b Non-volatile memory driver v1.3 Linux agpgart interface v0.103 agpgart-intel 0000:00:00.0: Intel 855PM Chipset agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xe0000000 Hangcheck: starting hangcheck timer 0.9.0 (tick is 180 seconds, margin is 60 seconds).

There were some recent exa breakages in git that resulted in this kind of corruption. The fix is on the xorg mailing list. Also mixing radeonfb and X is usually a recipe for problems.

The fix is on the xorg mailing list. Didn't try it yet. > Also mixing radeonfb and X is usually a recipe for problems. Then I guess I never had them :) To check back I updated my desktop, which is pretty much the same software-wise but has an r280 on agp, and it's all fine. Sure, that's not a proof, but it backs the chip-specific hypothesis. does this exa patch help? http://lists.freedesktop.org/archives/xorg-devel/2009-December/003818.html OK, scrap the chip specific theory. My desktop does show corruption - it just defaulted to XAA, while laptop (rv350) explicitly had EXA. I assumed EXA would be today's default. I'll check back in a few days when the latest round of EXA patches hit master. Just a question - Why do I get XAA by default on git drivers?

On my Radeon RV350 IGP and kernel 2.6.31.6, glyphs are rendered as solid blocks under EXA. Every glyph is rendered as a solid in the colour they glyph should take for Qt apps, in firefox things get even worse (see screenshot). I don't use KMS, xorg is from today. Switching to XAA fixes the issue. My other system running pretty much the same setup but with an r200 pci card runs fine so far under EXA, so it might be card specific: 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] (prog-if 00 [VGA controller]) Subsystem: Fujitsu Technology Solutions Device 1080 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11 Memory at d0000000 (32-bit, prefetchable) [size=128M] I/O ports at b000 [size=256] Memory at ffcf0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at ffcc0000 [disabled] [size=128K] Capabilities: [58] AGP version 2.0 Capabilities: [50] Power Management version 2 Kernel driver in use: radeonfb
