I know there are a lot of posts about nvdia driver, but I am not able to solve this.

I updated my configuration yesterday, September 27th, and it seems that a new nvidia driver was involved. The updated completed with an error, and invited me to send a bug report automatically. I send it, but it finally said that there was no place to send the bug report to.

Today I updated again, and a new kernel was there. Then I rebooted. I found a desktop in 640x480 with a horrible, unreadable font.

I run jockey and tried to go back to another version of the nvidia driver, but it seems that none of the drivers listed there are suddenly valid. I have the x-swat repository enabled, because I remember that I had a similar issue in the past that was only to be solved with the newest driver.
