Some more information from M6 LY world... 1) Starting from Karmic alpha-4 (LiveCD), which works, I can upgrade xserver-xorg-video-radeon to the karmic repository version, and xserver- xorg-core and all the -video packages, compiz, and hal/libhal, and finally install libdrm-radeon1 to get DRI functionality back (otherwise it tends to fall back on vesa). I can't upgrade libgl1-mesa-dri because of bug 420617. After all this, everything still seems to work fine, compiz effects and all. This makes me suspect libgl1-mesa-dri (or maybe the window-decorator?).
2) With the latest updates, the 'tartan' screen corruption still occurs if and only if DRI is off. By latest, I mean libgl1-mesa-dri/karmic uptodate 7.6.0~git20090817.7c422387-0ubuntu3 ubuntu-desktop/karmic uptodate 1.167 I'm not sure the best way to test this on the live CD - unload the drm module? 3) With the latest updates and if and only if DRI is on, I still get hangs/crashes where either (a) with NoTrapSignals left as false, I get reams of error messages like the above 'radeon_cp_start called without lock held', and a lockup where the cursor is stationary, and I can't attach a gdb. (b) with NoTrapSignals false, a crash in Xorg as follows: Sep 7 20:41:23 laptop23 kernel: [ 213.306512] Xorg[3115]: segfault at 14 ip 00f740c5 sp bfd247c0 error 4 in radeon_dri.so[f24000+255000] Sep 7 20:41:25 laptop23 kernel: [ 215.127370] agpgart-intel 0000:00:00.0: AGP 2.0 bridge Sep 7 20:41:25 laptop23 kernel: [ 215.127401] agpgart-intel 0000:00:00.0: putting AGP V2 device into 4x mode Sep 7 20:41:25 laptop23 kernel: [ 215.127433] pci 0000:01:00.0: putting AGP V2 device into 4x mode Sep 7 20:41:25 laptop23 kernel: [ 215.376447] [drm] Setting GART location based on new memory map Sep 7 20:41:25 laptop23 kernel: [ 215.376467] [drm] Loading R100 Microcode Sep 7 20:41:25 laptop23 kernel: [ 215.376513] [drm] writeback test succeeded in 1 usecs Sep 7 20:43:29 laptop23 kernel: [ 339.623068] Xorg[5247]: segfault at 14 ip 00f200c5 sp bfb98040 error 4 in radeon_dri.so[ed0000+255000] Would a core dump be useful? Also under the same conditions, I get the partial distortion of a window as shown in the 517K PNG. The easiest way to produce this is to drag a window over a window that does not have the focus. The segfault (or hang) is most easily produced by enlarging a window that is about 600w x 400h until it is say 1100w x 700h, or starting an application that would produce a larger window. 4) Ctrl-Alt-F1 isn't changing to text mode properly with the very latest updates. 5) I won't be able to confirm bug 404331 is fixed for me until this one is fixed, since if DRI is enabled, this bug happens more frequently. -- screen corruption and segfaults with radeon m6 ly https://bugs.launchpad.net/bugs/421842 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
