I had good running system of v10.04 Ubuntu on my old Acer TravelMate 630 laptop (about 8 years old) for months. Then I upgraded to v11.10 via Update manager and it went like charm. After that, I played with system tweaking, just trivial things like screensaver lock and wallpaper, until I "discovered" the option "Adding hardware driver" or something like that.
I let Ubuntu scan my system and it came back with a proprietary, but recommended Nvidia driver. Since my video play and flash rich sites was terribly slow, I hoped to get any improvement by installing something else than generic video driver.
Yes, I thought of my very old Nvidia Mobile2Go graphic card and 2GHz Pentium 4 as possible reason for not very responsive machine, but...
Anyhow, I let the system update my graphic card driver and it turned out it was a big mistake. After reboot I could not get into my X server anymore. Furthermore, I cannot get to text console neither. Only scrambled screen.
I can get into text console only trough the GRUB, by pressing shift.
I read a lot of postings in other forums about similar issues, tried many possible solutions, but none gave relief. I suppose, the main problem is, that I have only wireless Internet connection on my laptop and that is not active when I am in GRUB. I got to console after GRUB, but no command worked in it. In other words, I don't have got the Internet connection when I am in text console.
One thing more, I can start Live CD without any problem, but don't know what then.
Please, before I install the whole system from the scratch only because of failure of bad video card driver, could anybody tell me how could I get rid of that bad driver without new install?
Thanks very much in advance!
