If I do a standard boot of Linux Mint, it goes to the Login Screen, but as soon as I login, it flashes the desktop then the entire screen switches off - including the back light. Luckily, if I boot to Recovery Mode then 'resume', Linux boots normally. The only not-normal thing is when I login from 'resume' In recovery mode, there are strange shapes that appear on the screen made up from the desktop icons and picture.
Some things which I have tried:
- Running the various options in Recovery Mode
- Re-installing mate-screensaver
- Upgrading the entire system
- Deleting Heavy Duty apps - E.g. TeamViewer
sudo dpkg --configure -a
sudo apt-get install -f
None of these things have worked.
I'm not sure if this is relevant but when I run
lspci | grep -i --color 'vga\|3d\|2d'
The output is:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 0a)
