Nvidia Geforce 7300GT, restricted drivers -> failsafe graphics mode
It would appear that my Nvidia 7300GT doesn't like the 'nvidia' restricted driver. It's okay with Ubuntu's 'nv' one. (This is in Gutsy / 7.1, BTW.)
1) In Gnome, I open the "restricted drivers" screen and tick the box. Everything appears to work, in that it recognises my card and installs stuff.
2) Restart. But now we have low graphics mode, and a dialog "your screen and graphics card could not be detected correctly". It doesn't matter what I do here, I always get:
3) GDM login, low graphics mode. I log into Gnome again.
4) looking at the "screens & graphics" screen, I see I am using the Vesa driver; and the "plug and play" screen. Changing these settings does nothing; I can't even change back to the 'nv' driver (and yes, I've tried logging out, even rebooting).
4a) I can use the "test" button, though. If I change to the nv driver and change back to my normal monitor settings, then clicking it shows me a good high-res screen. Doing the same with the 'nvidia' driver makes the "screens & graphics" screen close (presumably, crash).
5) looking at /etc/X11 I can see I'm running from xorg.conf.failsafe, which appears to have been automatically generated. Presumably this is the correct behaviour for when the X setting doesn't seem to work.
6) /var/log/x11.?.log shows no errors -- it corresponds to the failsafe boot of X. I can't see anything in dmesg. (But of course I'll provide any outputs you request; just let me know.)
7) I *can* get back to the nv driver, by doing a 'sudo dpkg-reconfig xserver-xorg', answering all the questions, and *then* going into the "screens & graphics" screen. nothing else seems to work.
I have a motherboard with a graphic card built in and no way to turn it off in the BIOS -- perhaps that's something to do with it, although lspci only shows one graphics card so the motherboard has presumably switched out its graphics automagically. OTOH Ubuntu can't autodetect my monitor now.
I've tried Envy, with, I'm afraid, exactly the same results. I've tried installing the drivers directly from the Nvidia site, using the "nvidia manual" page on the wiki, and that was exactly the same, too. I've tried posting my problem in the forum, but got no response -- which I assume means that no-one knows the answer.
I'm afraid I'm out of ideas. Any suggestions would be greatfully appreciated.
Many thanks,
Andy.
