apport information
** Tags added: apport-collected xenial
** Description changed:
After upgrading from Ubuntu 14.04 to 16.04, the screen will stay black
after GRUB (backlight is on) when booting with the new 4.4 kernel
(linux-image-4.4.0-57-generic). Booting with the old 3.14 kernel will
make the screen work again.
This is on a BIOSTAR A780L mainboard, with the monitor connected via
DVI.
"ubuntu-bug linux" tells me that I appear to run a mainline kernel and
cannot report anything (obviously, as the screen doesn't work if I boot
the 16.04 kernel).
$ cat /proc/version_signature > version.log
cat: /proc/version_signature: No such file or directory
