I wanted to install KDE and Gnome along with Unity. I don't know when I installed gnome-shell on my Ubuntu 12.10, but I installed KDE minimal desktop just now using
sudo apt-get install kde-plasma-desktop
and selected lightdm as my default DM. Then I entered this to install gnome
sudo apt-get install gnome-shell
and it said I already have it installed.
So, then I restarted in normal mode and Ubuntu didn't start.
I went to recovery mode and from root shell I used
it throws these bunch of errors:
/etc/X11/X is not executable xinit: giving up xinit: unable to connect to X server: Connection refused xinit: server error
and when I tried
chmod +x /etc/X11/X
chmod: cannot operate on dangling symlink `/etc/X11/X'
I can't use apt-get to reinstall packages, because our ISP uses portal login - and I don't know how to login from terminal (so can't connect to network). May be I can use live disk, but I don't know how to configure packages on my HD from livedisk.
I am on Windows 8 now. Any help regarding how can I get my desktop back is appreciated!
