Brilliant work by SPARX there..!! After being frustrated by this problem
for months, i can confirm too that the solution in 71 works
I had this earlier but the problem still existed.
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_backlight=vendor
Looks like adding the pcie_aspm=force is the key
Been affected by this for several months now with no good solution in
sight. It also crashes when i use the change brightness option in the
user preferences. And of course it happens when i use the shortcut keys
to change brightness provided on the laptop. I have a dell inspiron and
the 64-bit
