The Cost Of Running Compiz

1 more for Kwin compositing comparison

As a long time Kubuntu user, I too would like to see a benchmark comparison between kwin and compiz.

I only play one game and that is UT2004. I have always needed to turn of Compiz when playing as I am a bit finicky when it comes to smooth gaming. Manually disable Compiz is not very convenient, so I used a script for that.

#!/bin/bash

kwin --replace &
ut2004 ;
killall -s USR2 compiz.real
compiz --replace & 
exit 0

This will stop Compiz when you start UT2004 and start it again when you quit UT2004 automatically.

This script is for KDE so you would need to change "kwin" to "metacity" (and "UT2004" for a different game) if you use Gnome. It has been a long time since I used this script (used it when I used KDE3) so it might not work any longer.



Now I use KDE4 and I made this script:

#!/bin/bash

kwriteconfig --file kwinrc --group Compositing --key Enabled false
kwin --replace &
ut2004 $@ ;
kwriteconfig --file kwinrc --group Compositing --key Enabled true 
kwin --replace
exit 0

This script will probably only work for KDE4. Perhaps it would help somebody.

You don't have to be so brute with kwin. Just ask nicely:

qdbus org.kde.kwin /KWin toggleCompositing

Interestingly, some time ago I was peeking at a friend's computer and I noticed that some applications do disable compositing on Windows 7. It made me laugh, because it seems that this is a problem everywhere

or just hit alt+shift-F12 to toggle composite.

Oh noes, that poor little kwin, i hope he get better soon. Are you sure, alt+shift-F12 really?

You know those ppl that only quote other ppl's howtos/scripts but never write anyone them selfe to help out?

Hope you understand my sarcasm...

[energyman]

oh no, I only toggle composite once every couple of weeks. Quickly, I have to hack an overblown script!

Or I just hit the key combo.

Which I can programm into my keyboard.

So it is one single keypress...

[Eazy]

hehe......

[energyman]

seriously,. 24 freely programmable keys with 10 layers (so 240 programmable positions) is just awesome...

Most of the time dwm.exe crashes.

Most of the time dwm.exe crashes.

Never seen any dwm crash. Broken ram perhaps?

Or broken system.
