Public bug reported: In addition to my system, this bug occurs on 3 other laptops in my lab (2x Thinkpad and 1x Macbook air). The bug seems 13.10 specific as other installations are not affected.
My Macbook Pro 11.3 has Kernel 3.13. When the screen freezes, sound (e.g., skype) still works and I can move the mouse but not click. I 'solve' this by going to the terminal and restarting lightdm by 'sudo service lightdm restart' but of course this is still not a real solution. It seems to me (but this is really just a speculation) that the freeze occurs more often shortly (10-60min) after connecting or disconnecting to/from an external screen. Sometimes, when I switch to tty1 to restart lightdm, the terminal is flooded with 'Wrong Mac address' messages but this is probably unrelated. I changed to gdm in hope that this may fix the bug but judging by the reports from this bug: https://bugs.launchpad.net/ubuntu/+source/xorg- server/+bug/1184451 this will not do the trick. Let me know if you need more logs, etc. Thanks, Krzysztof ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xorg 1:7.7+1ubuntu6 Uname: Linux 3.13.0-031300-generic x86_64 NonfreeKernelModules: wl .tmp.unity.support.test.0: ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None Date: Sat Feb 15 10:53:57 2014 DistUpgraded: Fresh install DistroCodename: saucy DistroVariant: ubuntu DkmsStatus: bbswitch, 0.7: added bcmwl, 6.30.223.141+bdcom, 3.12.0-031200-generic, x86_64: installed bcmwl, 6.30.223.141+bdcom, 3.12.0-994-generic, x86_64: installed bcmwl, 6.30.223.141+bdcom, 3.13.0-031300-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: NVIDIA Corporation Device [10de:0fe9] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Apple Inc.
