I have a similar error on my acer notebook (intrepid, I'm not running jaunty yet). I have an ATI graphics card installed (Mobility Radeon 9700 I think) and I'm running the ati (radeon) driver. Therefore I don't get the exactly same Xorg log as stated before, but the backtrace is nearly equal (the memory locations are slightly different), but I think this could be the same issue. Additionaly I'm able to reproduce this error, because I experienced it while coding a small game with some of my fellow students. We use SDL in conjunction with OpenGL and I was able to produce a little program that raises the error when started. To compile use $ g++ -g -gstabs -lGL -lGLU -lSDL crash.cpp This is quite weird. The xserver crashes not all the times the program is called. There are at least 4 possibilites that I noticed: * the xserver crashes (see Xorg.0.log) * the executable crashes, showing a backtrace leading to munmap_chunk() (see backtrace.1) * the executable crashes, showing a backtrace leading to a "double free or corruption" (see backtrace.2) * the executable crashes printing a nice looking XServer error:
Starting test Using software surface Video mode set, calling SDL_Quit X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x380000f Serial number of failed request: 127 Current serial number in output stream: 129 We're not that familiar with this SDL/OpenGL stuff, but the error (at least the xserver crash and the nice looking xserver error) is reproducable with the SDL-OpenGL-example by NeHe (http://nehe.gamedev.net), so I don't think we have such a big bug in our program. So if this is a bug in conjunction with OpenGL (which is quite obvious, because of the libglx.so entires in the xserver-backtrace), Jon Stumpf is using compiz propably (I'm not)? Unfortunately I cannot post a full backtrace, because I don't have a second machine available right now. If it is still needed, I could get one next week propably. ** Attachment added: "cpp source of the program that causes a crash" http://launchpadlibrarian.net/24432273/crash.cpp -- X server 1.5.2 aborts in __glxContextDestroy, within 15 minutes after login https://bugs.launchpad.net/bugs/303807 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
