I have been using Linux Mint (Cinnamon) for at least a year. Started with 18.1 and once 18.2 was available I did the upgrade to it. Everything has been working perfectly. Yesterday, when I turned on my computer it won't boot. I can see the grub2 menu, the Linux Mint logo being displayed and then I get a white cursor at the top left corner. Nothing else. I tried editing the grub2 load adding the "
nomodeset grub_gfxmode=1280x1024x24" but still having the same issue.
I was able to get to a command line by doing
F1, able to log in, I ran
sudo apt purge "nvidia-*" and then doing
startx starts the GUI. But for some reason I have now to do this every time I boot the computer (without the
sudo apt purge "nvidia-*").
More information that may help find the root cause and how to fix it:
/etc/X11/default-display-manager says "/usr/sbin/lightdm"
I tried running
sudo systemctl start mdm but got error "Failed to start mdm.service: Unit mdm service not found".
Update manager says there is no updates.
Running kernel 4.10.0-35.
Dual booting with Windows 7
I need your help to see what is going on and what made it fail, and hopefully be able to restore it (I have several files/configurations that need to preserve).
