Title:
kernel 3.13.0-83 regression : screen resolution too small
Status in linux package in Ubuntu:
Confirmed
Bug description:
After upgrade from linux-image-generic-3.13.0-77 to 3.13.0-83 the
screen resolution is reduced to 1024x768.
Rebooting in 3.13.0-77 solves the problem.
The screen is a IIYAMA ProLite E2207WSV, VGA Only, 1680x1050 60Hz
connected to a Nvidia Graphic card.
Some more information (with the working version of the kernel).
