That sounds like a good place to start.
Unfortunately my debian partition is now totally borked
for some reason yesterday I lost the ability to open readme files, so had to re associate them with gedit.
Then this afternoon I lost the gnome desktop, well I had a desktop with some icons, but no bar at the top to run anything, luckily I had a terminal shortcut on the desktop so I tried to reinstall gnome, which went through ok with no errors.
But after rebooting it I could not login to my profile at all, it just hung after entering my password.
I then tried the recovery mode, and was able to log into gnome with root profile, but almost all programs failed to launch - giving some error about d-bus.
The thing was I couldn't even bring up the network interface so couldn't try to reinstall those progs and dependencies, oddly the only things that seemed to work were apt-get and synaptic, but with no network they aren't a lot of good
So hay ho I am now running the net install again on a wiped partition and will try again !
Thanks for your help, I'm sure I will still need to do that fix afterwards !
