I've upgraded to Ubuntu 7.10, and now I seem to be having problems with both my wireless and graphics card. Any help would be greatly appreciated.
So I upgraded to Gutsy Gibbon last Friday night, and everything went smashingly -- until I rebooted for the first time Sunday morning. At that point (and ever since), I've been having problems with my wireless (using ndiswrapper) and video (Nvidia). To wit:
When I boot, the first symptom that something is awry is an 800x600 screen saying that Ubuntu's running in low-graphics mode. I'm given the option to Configure or Cancel, but configuring doesn't seem to do a dang thing -- I can pick the nv or nvidia drivers, but the test always fails and none of the changes I make seem to stick. So I click "Continue." The machine continues to boot, and I get the same message about 20 seconds later, click Continue. This goes on about three or four more times, at which I'm finally given an "X Server could not be started" error, the details of which have to do with failsafeXServer. It kicks me back to the CLI.
At that point, I do a sudo dpkg-reconfigure xserver-xorg and plow through all the prompts (selecting the default nv driver). Once it's done (at which point I get a warning about overwriting a previous custom configuration file), I can startx, and yay, I'm at my desktop.
At this point, however, I still have no wireless. A ping results in a "network not reachable" error. I do a dhclient, and then voila, I'm connected, and all seems right the world -- except that I can't seem to perform any administrative-type tasks (from the desktop), as I get an error "Can not run /usr/bin/whatever as user root. Unable to copy the user's Xauthorization file."
I've searched the Ubuntu forums (and even posted
a question of my own), but have had no luck trying to resolve this problem. Making things just a hair more frustrating is the fact that even once I get into GNOME, I have no mouse cursor -- the mouse works, but I have to guess where it is (or draw a trail and figure it out).
Sorry for the extended length, but I'm pretty sure these are all semi-related, and with my luck it's something stupid simple like a read-only filesystem or something.
