Bug ID: 101871
Summary: Video freezes if external display is attached/Yoga2 13
Pro
Product: Drivers
Version: 2.5
Kernel Version: 3.19.0-22-generic #22-Ubuntu SMP Tue Jun 16 17:15:15
UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - Intel)
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: kernel.org at eichelsdoerfer.de
CC: intel-gfx-bugs at lists.freedesktop.org
Regression: No
If attaching a external monitor to my laptop, very frequently the screen
freezes. Mouse still moves, but no action can be done on the windows. What can
be seen on the display is only a part of the desktop, no panel or Unity dock
can be seen. Suspend and resume doesnt help. Killing the lightdm restarts X and
resolves the issue, however all applications need to be restarted.
Relevant output in dmesg/syslog:
