My install was interrupted because of a power cut. I recovered from it, using the command
sudo apt-get dist-upgrade
Now, I get a violet bootscreen like normal, but the progress bar is shown as 4 dots, and Ubuntu is displayed in a simple font, reminiscent of the DOS era. What do I do to make it right? I have nvidia drivers. Also, worth mentioning is that before showing the bootscree, i get a line of text saying:
............ unreliable temperature sensor.............
I use a Asus M3N78-EM AMD Phenom II X3 720 Black Edition 4GB DDR2, Nvidia 9400GT 512 MB.
