I'm currently running Xubuntu 10.04 LTS and wanted to try out the SLiM display manager on my system.
Well I installed it (from the synaptic package manager) and something really bad happened; I can't even get to the display manage anymore to log in.
When I boot up normally, it shows the Xubuntu logo, then shows this one underscore in the top-left corner of my screen. I tried pressing "Alt+Ctrl+F1" to launch a virtual terminal but that didn't work.
I also tried to boot into recovery mode via GRUB. When I got to the recovery screen, if I were to press any of the arrow keys, the screen would show the Xubuntu logo. If I press the arrow key again, it would go back to the recovery screen, but it wouldn't move down an option.
It isn't too bad if I'll need to re-install Xubuntu (I backed up all my important data a day ago), but it would be a real pain in the but if I had to.
Any help is appreciated. Thanks!
EDIT: I forgot to mention that maybe resetting GDM to the default WM might fix it, but you see, I can't even log in to try to edit the "/etc/X11/default-display-manager" file.
EDIT2; I decided just to bite the bullet and re-install/update Xubuntu. Thanks for the help though.
