Bug#396037: libgl1-mesa-dri: i915 OpenGL severely broken
Yeah, sorry, that was a messy post. I hope this one is a bit better. * Behaviour with unstable packages: libdrm2_2.0.2-0.1_i386.deb libdrm-dev_2.0.2-0.1_i386.deb libgl1-mesa-dev_6.5.1-0.6_i386.deb libgl1-mesa-dri_6.5.1-0.6_i386.deb libgl1-mesa-glx_6.5.1-0.6_i386.deb mesa-common-dev_6.5.1-0.6_all.deb xserver-xorg-core_1.1.1-20_i386.deb xserver-xorg-video-i810_1.7.2-4_i386.deb As described in the initial bugreport: OpenGL apps don't work unless LIBGL_ALWAYS_INDIRECT is set. With LIBGL_ALWAYS_INDIRECT I get lots of rendering artifacts (e.g. the sun is missing a quarter of its halo in Celestia, textures blinking in nexuiz). (xserver-xorg-core is the only package that has changed here since the initial bug report. 1.1.1-18 = 1.1.1-20) * Behaviour with old experimental packages from previous e-mail: libdrm2_2.3.0-1_i386.deb libdrm-dev_2.3.0-1_i386.deb libgl1-mesa-dev_6.5.2-3_all.deb libgl1-mesa-dri_6.5.2-3_i386.deb libgl1-mesa-glx_6.5.2-3_i386.deb mesa-common-dev_6.5.2-3_all.deb xserver-xorg-core_1.2.0-4_i386.deb - LIBGL_ALWAYS_INDIRECT causes the exact same rendering bugs but OpenGL programs now work properly _without_ it (although with a warning about a missing visual). - Putting Option XAANoOffscreenPixmaps in the device section fixes at least a bug with Beryl/Compiz where windows don't redraw themselves in texture from pixmap mode. Load dbe in Section module doesn't seem to have any effect after all. * Behaviour with latest experimental packages: xserver-xorg-core_1.2.99.903-1_i386.deb xserver-xorg-video-i810_1.9.93-1_all.deb xserver-xorg-video-intel_1.9.93-1_i386.deb Same as with the previous experimental packages as far as I can tell except for some new issues: - Exiting X or switching to a console VT while beryl is running almost always causes the machine to freeze! - Even when Beryl is not running X prints the following on exit: (EE) intel(0): I830 Vblank PipeSetup Failed 0 - X also always prints the following warning while starting up: (WW) intel(0): xf86AllocateGARTMemory: allocation of 10 pages failed (Cannot allocate memory) - Some of Beryl's Emerald themes render incorrectly. So the best combination for me was: - Mesa 6.5.2-3 - libdrm2_2.3.0-1 - xserver-xorg-core_1.2.0-4 - xserver-xorg-video-i810_1.7.2-4 (the one in unstable) - NO special envvars - Option XAANoOffscreenPixmaps if running Beryl or Compiz. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

forwarded 396037 https://bugs.freedesktop.org/show_bug.cgi?id=9199 thank you Martin Pärtel wrote: xserver-xorg-video-i810-modesetting_1.7.2.git20070210-1_i386.deb (also tried without the modesetting driver; no difference) The backtrace indicates either a problem in the i915 module (libgl1-mesa-dri package) or in /usr/lib/xorg/modules/extensions/libglx.so (xserver-xorg-core package). The i810 driver does not seem involved. I found the same backtrace on the same graphic board in the upstream bugzilla at https://bugs.freedesktop.org/show_bug.cgi?id=9199. There has been no reply so far, but the bug was not against the right component, so... I reassigned it correctly. It would be nice if you could summarize all your conclusions there. Note that I found your last mail pretty hard to understand since there are lots of combinations of modules/envvar/packages involved. It would be nice to explain in a simple way how to reproduce the bug and what works around it. Note that upstream does not really like old versions, so be prepared to have to reproduce with xserver-xorg-core (2:1.2.99.903-1) or xserver-xorg-video-intel (2:1.9.93-1) currently in experimental :) Mesa 6.5.2-3 is fine. At first OpenGL apps were much slower and had different (but still ugly) rendering artifacts than before, but after adding Load dbe and Option XAANoOffscreenPixmaps (not sure which one helped, sorry) to xorg.conf the speed went back to normal. Adding those options didn't seem to have change anything after I had reverted back to sid packages. Hum, I don't know anything about this dbe option... So, the working combination was: - experimental packages (except i810-modesetting) - Load dbe (or Option XAANoOffscreenPixmaps?) - _no_ LIBGL_ALWAYS_INDIRECT. All at the same time? Or any of these lines? Thanks a lot, Brice
Bug#396037: libgl1-mesa-dri: i915 OpenGL severely broken
Hi Brice, Yes, the problem still exists, although with LIBGL_ALWAYS_INDIRECT enabled programs no longer tend to crash. I tried with the following experimental packages: libdrm2_2.3.0-1_i386.deb libdrm-dev_2.3.0-1_i386.deb libgl1-mesa-dev_6.5.2-3_all.deb libgl1-mesa-dri_6.5.2-3_i386.deb libgl1-mesa-glx_6.5.2-3_i386.deb mesa-common-dev_6.5.2-3_all.deb xserver-xorg-core_1.2.0-4_i386.deb xserver-xorg-video-i810-modesetting_1.7.2.git20070210-1_i386.deb (also tried without the modesetting driver; no difference) At first OpenGL apps were much slower and had different (but still ugly) rendering artifacts than before, but after adding Load dbe and Option XAANoOffscreenPixmaps (not sure which one helped, sorry) to xorg.conf the speed went back to normal. Adding those options didn't seem to have change anything after I had reverted back to sid packages. With the experimental packages the LIBGL_ALWAYS_INDIRECT envvar caused the exact same rendering artifacts as with unstable packages. After adding the above options to xorg.conf, things worked perfectly, but only without LIBGL_ALWAYS_INDIRECT. So, the working combination was: - experimental packages (except i810-modesetting) - Load dbe (or Option XAANoOffscreenPixmaps?) - _no_ LIBGL_ALWAYS_INDIRECT. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Hi Martin, Do you still reproduce this problem with latest Xorg/Mesa in Etch? If so, could you try the experimental packages? Brice -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Bug#396037: libgl1-mesa-dri: i915 OpenGL severely broken
Package: libgl1-mesa-dri Version: 6.5.1-0.2 Severity: important OpenGL apps are terribly slow or don't work at all unless LIBGL_ALWAYS_INDIRECT is set. e.g. glxgears renders nothing and prints: libGL warning: 3D driver claims to not support visual 0x5b do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly. Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset. Celestia works but has major rendering artifacts. Many OpenGL apps crash the X server either every time (a Qt4/OpenGL app of mine) or occasionaly (flurry screensaver).
