Linux DE Freeze Solution

Have you ever had your Linux desktop environment freeze on you? Most people will just hard boot the machine to get it working again. Here's a better way...

On your keyboard press and HOLD:

Alt + PrtScrn/SysRq

then type in this order:

R S E I U B

While holding each key, one a time. The machine may restart after the B.

This sequence of commands takes back the keyboard from X, shuts things down properly, and reboots the system.

• unRaw (take control of keyboard back from X),
• tErminate (send SIGKILL to all processes, forcing them to terminate immediately),
• kIll (send SIGKILL to all processes, forcing them to terminate immediately),
• Sync (flush data to disk),
• Unmount (remount all filesystems read-only),
• reBoot
