Bad video signal after upgrading to Interpid

[Joseph]

After upgrading to intrepid from 8.04.1 and restarted the computer, I got a bad video signal.
I tried to switch to the console screens (e.g. Ctrl-Alt-F1), but the text was not readable.
One way to get the graphics to work was to reboot in recovery mode to fix it.

It seems that the correct package nvidia-glx-96 was installed on my system, but I have read that it is not compatible with xserver 1.5. If this is the case, I should have received a dialog to change the settings.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Please include the information requested at https://help.ubuntu.com/community/DebuggingXAutoconfiguration as separate attachments.

I've attached what was asked for in the linked provided.
In case you need more information, let me know.

I'm also having this problem -- some sort of indication would have been nice. Is there a way of downgrading the xserver to make the driver compatible? I'm assuming that otherwise we'll have to wait for nvidia to release appropriate drivers.

Update Manager will deal with the migration to the free driver until the proprietary driver supports the new Xorg.

Thanks for your bugreport.

This is fixed in the latest version of update-manager that is now in the archive. It will warn about the driver and remove it (replace it with the free "nv" one).
