I've just installed a clean version of 11.04 and I am trying to get the NVIDIA driver to work.
Just after installing I've seen Unity and used it. Then I activated the NVIDIA driver (from the additional drivers dialog) or I just restarted (I don't remember well anymore) and I got a message telling me that Unity didn't want and I got into classic mode.
In the additional drivers dialog it says the NVIDIA driver is "activated but not currently in use". I found out that I should do a
sudo nvidia-xconfig, which gave back:
Using X configuration file: "/etc/X11/xorg.conf".
VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf. Device section "Default Device" must have a Driver line.
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup' New X configuration file written to '/etc/X11/xorg.conf'
(Exactly as posted on the ubuntuforums before. I also have the same version, "nvidia-xconfig: version 270.41.06".)
After I reboot I can see the Ubuntu logo bith the four dots starting up and then only a console with some starting messages:
- Starting ACPI deamon [ OK ]
.. more of such starting messages ..
modem-manager: ModemManager (version 0.4) starting...
.. and more modem-manager loading plugin messages ..
.. and ending with:
- Stopping Flush boot log to disk [ OK ] Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox
[ OK ]
And then nothing happens anymore. I stay in this console and can't get into a graphical mode in a normal way.
I can reboot in recovery mode and start a classic GUI, replace the xorg.conf with the backuped one and have everything working again. And thus also repeat this whole process over and over again. But the NVIDIA driver is still "not currently in use".
Anyone knowing a next hint to help me further?
