[Kernel-packages] [Bug 1562510] Re: Crash on Thinkpad T420s when battery goes low
It only started after the upgrade. The last kernel I ran which worked perfectly
fine was kernel
3.13.0-83-generic:i386. The bug seems to not be present with the 4.5 kernel,
though I've only done minor testing.

I'm running Ubuntu 14.04 and here is the output of xrandr: $ xrandr Screen 0: minimum 320 x 200, current 1600 x 900, maximum 32767 x 32767 LVDS1 connected primary 1600x900+0+0 (normal left inverted right x axis y axis) 309mm x 174mm 1600x900 60.0*+ 40.0 1440x900 59.9 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x60060.3 56.2 640x48059.9 VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) LVDS1 is the LCD-display on the laptop. This is the output of lspci: $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [NVS 4200M] (rev ff) The screen recognises that something is plugged into the DisplayPort but Ubuntu is unable to send output to it. It's probably related to the whole dual graphics card thing. Thank you for reading this bug!
