I bought a laptop (Asus, i686 architecture) only with pre-installed Debian 7. However, then I found that when I moved mouse horizontally, the screen shakes horizontally as well. Therefore I decided to update Intel Graphics Driver (before I was making updating, I installed
KDE Plasma 5 for my system).
After updating, my desktop environment automatically returned back to
KDE has been automatically uninstalled, I don't know why). Unfortunately, I found that I can not open either the root terminal or nautilus in
GNOME, as I click on it, the interface will show up for no more than 1 second and then shut down.
So how can I fix this problem? Do I need to recover Debian using GRUB, if so, how can I do that?
