Public bug reported:
After upgrading to 16.04, my thinkpad x1 carbon (3rd edition) freezes
and reboots when I attach an external display.
Process:
- put laptop to sleep.
- come into work the next day
- open up laptop
- plug in external display
- observe bug
Expected behavior: I can attach the external display
Observed behavior: system shows black screen on both laptop and display and
after a minute or two reboots. Laptop drives external display fine after
reboot.
I ssh to the laptop from another machine and monitored /var/log/syslog,
/var/log/Xorg.0.log, and ~/.xsession-errors. All I see in those files
before the lockup is this, from Xorg.0.log:
[ 34289.447] (II) intel(0): Enabled output DP1-8
[ 34289.448] (II) intel(0): Enabled output DP1-1
[ 34289.460] (II) intel(0): resizing framebuffer to 2560x1440
[ 34289.482] (II) intel(0): switch to mode 2560x1440@60.0 on DP1-8 using pipe 0,
(0, 0), rotation normal, reflection none
