I recently turned on compositing in my laptop using the following command:
gconftool-2 -s --type bool /apps/metacity/general/compositing_manager true
Performance seems to be same after that except for the fact that there's a small noticeable delay in switching windows now when I hit Alt+Tab. Also, there's now a bit of lag when I play a game called teeworlds (not graphics intensive).
My laptop is low-end so I'm not sure if it's just my video card. I'm debating if I should install the proprietary drivers to improve performance. Can I get some advice on this?
lspci | grep -i VGA is as follows:
01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200]
I'm not sure as to what drivers I'm currently using, all I know is that I didn't touch it since installing Karmic 9.10 so I know I'm using an open source one. I'm currently using 10.04 LTS (upgraded, not a clean install).
