I have intel i915 graphic driver. Sometimes I get black screen, I have a shortcut for sudo service lightdm restart
but it doesn't fix black screen problem. How can I reload graphic driver?
EDIT: It happens during heavy load of CPU, once it happened while scrolling chromium page.
Output of xrandr:
xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 32767 x 32767
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm

640x480 59.9

TV1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
EDIT2:
Though I accepted the below answer which was posted by terdon
, after I tested it many times I must note that it doesn't work.

I don't know if this will solve your issue, you might have a different problem to mine. In my case, the black screen happens when the computer has been left alone for a while and the screen has turned off. While moving the mouse or pressing a key wakes it up, the screen remains black.
My workaround is to run an
xrandr
command that sets up my screen again. In your case, the command would be:If that does not set up the correct resolution, use this one instead:
However, that's hard to type on a black screen. So, make a little script that runs this command:
The command above will create a file in your
$HOME/bin
directory (if the directory does not exist, create it withmkdir ~/bin
) calledfix_screen
. Now, make the script executable:Finally, assign a shortcut to it. Open the Settings dialog:
Then, go to Keyboard => Shortcuts => Custom Shirrtcuts and click on the + sign:
And then enter this:
Finally, choose a shortcut for it. Just click on
Disabled
and then type the shortcut you want:Now, the next time you have this black screen issue, just use the keyboard shortcut and everything should be fine.
