Marking this bug as not a duplicate of bug #492782 . Attempting any work-around suggested in that bug causes the system to freeze up and then shut down. I believe the root cause here is something deeper than the video layer. The last bit of the kernel log today was:
Feb 28 10:05:50 A123501 kernel: [400832.734646] lo: Disabled Privacy Extensions Feb 28 13:20:12 A123501 kernel: [412494.526923] lo: Disabled Privacy Extensions Feb 28 15:06:38 A123501 kernel: [418880.025122] [drm] nouveau 0000:02:00.0: EvoCh 0 Mthd 0x0000 Data 0x00000400 (0x0002 0x01) Feb 28 15:10:07 A123501 kernel: [419088.913403] [drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc ffff88021afb0800 Feb 28 15:10:53 A123501 kernel: Kernel logging (proc) stopped. I have not been able to reproduce this issue with less than about 4 days on the kernel timer. Are there any other log files I should upload? Is there a recommended way to stress the kernel so that I can reproduce this faster than four days? I will also try the mainline kernel to see if I can reproduce it there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716147 Title: cursor disappears on one screen of dual monitor setup -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
