** Description changed: Binary package hint: xorg I'm using a Thinkpad T30 with a builtin Radeon Mobility M7 LW [Radeon Mobility 7500] card. When upgrading to the Intrepid release candidate, almost everything worked except compiz. There were apparently no borders, and there were several graphical glitches. For instance, gnome- terminal was all white. I'm using the radeon open source driver which has worked flawlessly in Hardy. Tracking the problem, compiz --replace gave the following: /usr/bin/compiz.real (core) - Warn: No GLXFBConfig for depth 32 /usr/bin/compiz.real (core) - Info: Couldn't bind redirected window 0x30005f1 to texture That message repeated forever. This happened in 16bit color depth, 1024x768. When I tried 24bit, there were no visual problems anymore, only everything running really, really slow. My card has only 16 MiB of VRAM, so the probable explanation there is that compiz can't handle the textures at that color depth. 800x600x24 worked, but I would rather use metacity than a 800x600 compiz. In the #compiz IRC channel, I together with a few compiz developers successfully confirmed the bug on a Gentoo machine running Xorg 6.9.0 and a similar card, though with 32MB of ram. The conclusion we came to is that between Hardy and Intrepid there has been a regression in the radeon driver that borked the 16bit mode. This wouldn't be a problem for people running cards with more memory than 16MB since they can switch to 24bit depth. The bug also exists in the exact same form on the latest LiveCD. Steps to reproduce: 1. Use a Radeon Mobility M7 LW [Radeon Mobility 7500] with 16 MB of VRAM 2. Switch to 16 bit mode (24bit is the default) 3. Restart X - This bug is important since it affects -all- owners of Thinkpad T30 - laptops, as well as other owners of the M7 card. + This bug is important since it affects -all- owners of Thinkpad T30 laptops, as well as other owners of the M7 card. + [lspci] + 00:00.0 Host bridge: Intel Corporation 82845 845 [Brookdale] Chipset Host Bridge (rev 04) + Subsystem: IBM Device 0220 + 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] + Subsystem: IBM Device 0517
