I can't recover from the screen being off without resetting the laptop using the power button.

When I use the fn+volume keys while the screen is off I can hear the volume changing, I just can't find a way to get the screen to come back on.

I am using a Samsung Q45 laptop. I can pull any debug/system info and paste it in if someone tells me the commands to run.

Here is the link that crashes (crashes in both Firefox and Chromium):

I suggest you look at the contents of the file /var/log/syslog Each line starts with a timestamp. Find the section that coincides with the time the screen goes blank and see if you can find any relevant entries. I experienced a similar problem and the entries in my syslog file started... (timestamps at start of each line removed for clarity)

 [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
 [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel

I posted a bug report at freedesktop.org No fix yet but hopefully the bug report will help get it fixed.
