I have just downloaded and installed Ubuntu 12.04 in my old Sony Vaio VGN-FZ21M. On the first boot i did the update&&upgrade and i notice that there was a notification icon on the top right corner saying that a nvidia driver was installed (although not sill activated. After that i did the upgrades indicated in the Upgrade Manager Window. After this upgrades i was asked to reboot my laptop. The laptop booted with the new nvidia driver activated and the definition was just fine.

I checked with the command: " sudo lshw -c video " and the driver in use was nvivia (driver=nvivia).

The problem came after a second reboot. Now it appears that the driver wont load and i have a bad display definition. Maybe now i am using some integrated graphics card?

I have searched this forum, and others, but did not get the answer to how to solve this.

Now when i run " sudo lshw -c video " i have no indication of driver=nvidia

The output of "lspci |grep VGA" is NVIVIA Corporation G86M [GeForce 8400M GT] (rev a1)

One thing did notice was that at the boot that went fine, before i got the colored screen, i could see a couple of messages related to "UVC video probe control". Now i don't see this messages anymore when booting. Is this related?

Can you help? Should you need any other info, or output, just let me know. Thank you.
