Hi, all,
I seem to be hitting another Linux Learning Curve(!), and need to ask for a bit of help, please.
From what I've read it looks like I should try the following:-
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:-
It's butting up against my terminal command knowledge at that point.
Thanks,
Ian
I seem to be hitting another Linux Learning Curve(!), and need to ask for a bit of help, please.
From what I've read it looks like I should try the following:-
- Boot from live DVD and run the memory test, to verify that it is not a memory hardware issue,
- Boot from live DVD anyway, and check again that it isn't a more general USB port/sticks issue,
- If it freezes again when ejecting USB stick in Thunar, try restarting X (question on this below),
- If it freezes again, can I open a virtual console (question on this below),
- Can I CTRL-ALT-DEL from laptop internal keyboard and restart,
- Try manually dismounting from terminal instead of Thunar and see if it still freezes (I'll close Thunar first).
- Hold SHIFT(?) on boot at try an earlier kernel if available,
- Try an earlier restore point.
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:-
- Is CTRL-ALT-BACKSPACE enabled or disabled in LL3.8?
- 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?
- How could I try restarting X should I be able to open a virtual console?
It's butting up against my terminal command knowledge at that point.
Thanks,
Ian

Don't worry about artificial intelligence. Worry about natural stupidity.
