X server gpu usage
I wonder, how much does the X server and both Gnome and KDE stress out and use the gpu(ram and processing power)?
Can anyone compare it to Aero from Win7?
I was thinking that ideally, everything shiny that is included in the DE should be in the gpu's ram. Lets say I have VLC running with the Gnome gui - are all the icons and things that the gui uses in gpu ram and animating buttons etc does not use the cpu at all or does the cpu do it?
Ideally, a program on Linux should run and react as fast as if you typed it in the terminal without gui and shouldn't take more ram when running with a gui or without it.
