[URGENT!] GTK+ crashes

Postby ObelixXXL on Tue Jan 21, 2014 2:08 pm

I have a backup of all my GTK+ themes from the last Linux Mint 16 installation. I decided to copy them to the themes folder of LMDE just to save time from downloading all over again. This is where things went wrong. After changing a control theme to one of my backed up themes, nemo exited, the screen became black. I can't even open the terminal windows (There was a quick splash but nothing happened afterward). I am still able to open a few applications like Firefox, Banshee, VLC, but other more important programs like system setting, terminal etc. are all inaccessible. What should I do now. I have just installed LMDE (and it was a really tough process as I have Intel ivy bridge processor). Give me a hand please :(

Linux Mint is funded by ads and donations.

Most probably the theme you've selected uses Unico engine, and you've been hit by this bug.

If you're still able to open Cinnamon settings from Cinnamon's panel (though I doubt it because it's GTK+ 3 again), go there and change the theme to anything not using Unico (like Mint-X, for example).
If not, the best you can do is to remove Unico from the system. Switch into the system console by pressing Ctrl-Alt-F1, log in as root and run this to remove the package:
Code: Select all
apt-get remove --purge gtk3-engines-unico

Switch back to Cinnamon by pressing either Ctrl-Alt-F7 or Ctrl-Alt-F8 (usually the last one works).
If things are still broken, log out and log in back.
