Screensaver Freezes in Ubuntu 11.04

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

pgrep gnome-screen

this command will show the process id for Gnome Screensaver

Now we will need to kill the process using the kill command

kill 3312

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
