After a compiz traditional crash my top toolbar disappeared. What can I do now? [closed]
Solution 1:
Option 1:
Switch to a tty, and do some geeky debugging.
Pressing Ctrl+Alt+F1 through F6 switches to tty1
through tty6
respectively. A tty
is a virtual terminal. log in to your account, and in case of a crash, submit a bug report. (Answer by Me)

To restart Graphical User Interface -
sudo service lightdm restart
This will log you out in GUI and gets you back to login screen. If you use a non-default display manager, replace
lightdm
withkdm
orgdm
as appropriate. -
In most cases, restarting unity should work.
unity --replace
This will restart just Unity. Any open applications will remain open, and is hence safe and better to try this before restarting DM. If the command exits with
137
; retry it. It works. If the command exits with1
, Retrying it will have no effect. It will continue to fail.Remember to switch to graphical console on tty7 after running this. (Ctrl+Alt+F7 )
Option 2:
The magic SysRsq combinations are guaranteed to work. there are a whole lot of them, and googling may help.
For now, we are particularly interested in Alt+PrintScr+K, which kills all processes on a tty, so while on tty7
( the default one with graphics) it kills Xserver and brings you back to login screen.
