How much memory will be saved if the x/gui is not started?

How much memory will be saved if the x/gui is not started?

Is it recommended to disable it on 24/7 systems with only 256mb memory?

It depends on the DE/WM used (GNOME and KDE take up more than Fluxbox, for instance) and the applications running. In general, there is no reason to run a GUI on a dedicated server machine so most admins don't bother to have one running.

why don't you just start it and see how much it uses?

Slackware laptop: 600 MHz Pentium M, 192 MB RAM, Fluxbox and KDE (sorry no gnome)...

No GUI: ~ 12 MB mem usage (not including buffers/cache)
Fluxbox: ~ 29 MB mem usage (not including buffers/cache)
KDE: ~ 55 MB mem usage (not including buffers/cache)

Fluxbox and KDE numbers were taken after the GUI loaded fully, before opening any applications. "No GUI" number was taken immediately after boot, before launching Fluxbox or KDE.

No swap usage in any of the cases listed above...and it'll obviously vary with services you have running and use this simply as a ratio, not exact measures that hold for all machines!

Hope this helps...
