I had Ubuntu 10.10 running on my PC for a long time, and I was quite happy with the desktop performance (i.e. almost no lag while moving windows or shortcuts like alt+tab andctrl+alt+t all was so fast even when there is an installation or file copy/paste.
But now I have installed Ubuntu 14.04, and the new desktop environment is very user-friendly and nice looking, but the speed has gone.
I think after a certain version (11?), when the left sidebar (launcher?) arrived, this lag existed on my computer. So I think I want to reduce visual quality in exchange for speed.
So -how- can I get the simple desktop as in 10.10 back?
P.S. A few years ago, I tried something with Ubuntu 11. Changing the desktop environment to GNOME I think. But it was causing a lot of problems (like in
Compiz), so I would prefer a safe solution, if possible :)
Thanks for any help!
