i am running dual boot os machine including windows7 and ubuntu. few days back, i did update to 12.10 version, and at that time i was using gnome fallback desktop environment.
while doing update, i could see in remove obsolete packages, it removed some gnome related files. and at that time i was using gnome fall-back desktop environment with clear looks theme, because i did not like unity much.
when i restarted machine, it gave me option to select Ubuntu / windows7, when i selected ubuntu, it showed me ubuntu logo, but from that point, only black screen would remain there, and no login screen would come, no matter how far i waited.
using advance options in menu (and askubuntu/ubuntu forums) i tried following methods, but to no avail.
- booting to old kernel 3.5 and 2.6/2.4.
dpkg-reconfigure gdm(and both lightdm), setting it to lightdm. and restarting lightdm
sudo /usr/lib/lightdm/lightdm-set-defaults -s ubuntu-2d(no use)
chown username:username .Xauthority(its already on my username)
/usr/sbin/lightdm(it was already there)
and one more doubt:
some solutions suggest to install and reinstall packages, for e.g
sudo apt-get install --reinstall ubuntu-desktop
how do i install packages even after enabling networking, if i need a manual login, on web page provided by my ISP for starting internet connection.
