I’ve recently updated from Ubuntu 10.10 to 11.04 and found that whenever my screensaver activates the whole computer Freezes, I managed to solved the problem as discribed below.
Open a new Terminal Window and uninstall Gnome Screensaver by using the command below
sudo apt-get remove gnome-screensaver
Then we need to kill the Gnome Screensaver process, once again in the command line type in the following code to find the Gnome Screensaver’s process id
this command will show the process id for Gnome Screensaver
Now we will need to kill the process using the kill command
Replace 3312 with the Gnome Screensaver process id
Now we will need to install xscreensaver by using the following command
sudo apt-get install xscreensaver rss-glx xscreensaver-gl xscreensaver-data xscreensaver-gl-extra xscreensaver-data-extra
Now the final step is to Open the Screensaver Preferences under System->Preferences->Screensaver
If asked to launch the XScreenSaver daemon press OK, slect your screensaver and no more Freezing
