I have what I think is the same bug, on a Lenovo X301 with an Intel graphics controller. xrandr changes tend to crash about half to two thirds of the time.
Backtrace from Xorg.log when the crash happens: Backtrace: 0: /usr/bin/X(xf86SigHandler+0x65) [0x480f35] 1: /lib/libc.so.6 [0x7fbaf5669060] 2: /usr/lib/xorg/modules/extensions//libglx.so(__glXDeassociateContext+0x35) [0x7fbaf4b44375] 3: /usr/lib/xorg/modules/extensions//libglx.so(__glXContextDestroy+0xf) [0x7fbaf4b406ef] 4: /usr/lib/xorg/modules/extensions//libglx.so [0x7fbaf4b4c902] 5: /usr/lib/xorg/modules/extensions//libglx.so(__glXFreeContext+0x6c) [0x7fbaf4b428ac] 6: /usr/lib/xorg/modules/extensions//libglx.so [0x7fbaf4b428f3] 7: /usr/bin/X(FreeResourceByType+0x105) [0x435505] 8: /usr/lib/xorg/modules/extensions//libglx.so [0x7fbaf4b3f1fe] 9: /usr/lib/xorg/modules/extensions//libglx.so [0x7fbaf4b42bd2] 10: /usr/bin/X(Dispatch+0x364) [0x44d6e4] 11: /usr/bin/X(main+0x45d) [0x4336fd] 12: /lib/libc.so.6(__libc_start_main+0xe6) [0x7fbaf5654466] 13: /usr/bin/X [0x432ad9] Saw signal 11. Server aborting. The common culprit seems to be libglx.so, but this is part of xserver- xorg-core, so why is this bug filed against mesa? -- crash of Xorg using xrandr https://bugs.launchpad.net/bugs/273505 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
