System freeze on ejecting USB stick

[firenice03]

[size=1em]But I need a bit of help with some of this please.The Ubuntu keyboard shortcut to restart X is CTRL-ALT-BACKSPACE.  However, this is disabled by default in Ubuntu but re-enabled in Gnome in the keyboard settings:-[/size]

• [size=1em]Is CTRL-ALT-BACKSPACE enabled or disabled in LL3.8?[/size]
  
• [size=1em]There seems to be no setting I can find in the keyboard settings in LL/XFCE to enable the shortcut if it is disabled, in which case how can I enable or how do I assign a shortcut?[/size]
  
• [size=1em]How could I try restarting X should I be able to open a virtual console?[/size]
  

[size=1em]So not 100% these are exactly what you're needing but may give aid till others arrive[/size]  

[size=1em]- If you're in terminal; the reboot command will initiate a system reboot..[/size]
[size=1em]- Using the command startx should initiate the gui from a tty session; Ctrl Alt F7 should as well, whereas Ctrl Alt F1-F6 are other tty's[/size]

Code:

reboot
startx
