Hi,

i am using Ubuntu 8.04.1 and did a security update yesterday morning. Since then i am having massive problems:

The screen turns black regularly and I have to switch to the console with Ctrl+Alt+F1 and back to get it visible again. It is flickering, too. And it is make a deep humming sound if i connect the audio output to the integrated speakers of my monitor.

Loading webpages in Firefox and nfs access is very slow.

Changing the screen resolution in System | Settings is ignored. Chaning the refresh rate from 50 to 56 does not change anything. I have an nvidia graphics card.

Reinstalling the nvidia driver does not change anything.

There are no strange messages in /var/log/syslog
