I am using a Linux mint 14 (32-bit) USB boot-drive. I booted up, made an account, established wifi and installed some progams.
The problem is that Mint will randomly freeze upon performing an action. The first time it happened, it was when I tried to add GIMP to the panel. The second time, was when I tried to change the Mint theme.
The screen will freeze, and I cannot click ANYTHING. I can still freely move the cursor, but can't click on anything. Pressing keys has no effect either.
I can still use the touchpad sound switch, wifi switch and volume slider on my notebook. It shows absolutely nothing on screen, but still plays the notification sounds.
When this freeze occurs, the only option is to hold down the power button until my laptop cuts the power.
SIDE NOTE: Now that I've booted again, I can't change the theme anymore. Double clicking an icon has no effect.
Does anyone know what could be causing this freezing issue?
