I am on Ubuntu 11.10. I hope to be able to replace gnome-screensaver with xscreensaver. I have read instructions on many sites that one simply uninstalls gnome-screensaver and then installs xscreensaver.
However, when I request removing gnome-screensaver, the system wants to remove much more than just the gnome-screensaver.
TheGeeko61> sudo apt-get remove gnome-screensaver
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
gnome gnome-core gnome-screensaver
0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
After this operation, 483 kB disk space will be freed.
Do you want to continue [Y/n]? n
Abort.
(Surely they cannot collectively add up to only 483 kB.) Must I really remove gnome and gnome-core?
You do not really need to remove gnome-screensaver , disable gnome-screensaver (and enable xscreensaver) in
gnome-session-properties
If you really wish to remove it you may as gnome and gnome-core are meta packages, similar to ubuntu-desktop. meta packages are a list of packages to be installed.
See Ubuntu Wiki Metapackages for details
