Title:
Kernel crashes
Status in linux package in Ubuntu:
Incomplete
Bug description:
Recently, Ubuntu moved to kernel 4.4.x. On my ASUS X751L, this results
in my LVDS+external VGA displays to regularly go to sleep/energy
saving mode (even when being actively used) or to "scramble". As a
consequence, I reverted to kernel 4.2.0-35-generic. This worked very
well until I dist-upgraded last thursday. Now, the computer crashes
regularly, notably when it is (xscreensaver-)locked (mostly while
executing the "molecule" (OpenGL) screensaver).
I'm not sure if the crash occurs because of kernel, xscreensaver or an
mplayer script I run with cron to play a beep every hour (don't ask
why...).
This is a critical crash, so I assume there is a security issue
behind...
Some extracts of my syslog:
