I recently installed Ubuntu 12.10 on my laptop. It installed successfully, but whenever I boot into it, after the GRUB screen I get a text TTY. I can log in with that and enter command-line commands.
I have tried:
startx. After initializing extensions, it tries to load extension GLX and then has a fatal error, "no screens found". Looking at
/var/log/Xorg.0.logshows that "Screen(s) found, but none has a usable configuration."
sudo Xorg, which did the same as
removing and reinstalling
apt-get. This ran successfully but didn't seem to change anything.
sudo dpkg-reconfigure xserver-xorg, which seemed to have no effect and didn't output anything.
gnome-session, which says that it "could not open X display".
sudo service gdm restart, which makes the screen flicker a few times and then seems to have no effect.
/etc/X11/xorg.conf, but that turns out to not exist.
changing the "Configured Video Device" in
vesa. This seemed to have no effect.
~/.Xauthority, which also seemed to have no effect.
Other relevant facts:
nomodesetto the GRUB boot options. Not doing this causes the screen to just go black and stay black.
The laptop had UEFI which made installing Ubuntu difficult, but that seems to be disabled now.
The graphics card is Nvidia GEForce GTX, 670M and 30GB.
I can't easily post log files here because I have no way of getting them off the computer short of typing them up manually. I'm a newbie, so if there's a workaround please share!
Thanks for all help! :)
