[SOLVED] Compiz once closed, doesn't restart

[sayakb]

Dealing with a 1 year old laptop (T5500, 1GB RAM, Intel GMA950/945GM Onboard, 320GB HDD) here.

If I switch to metacity, I cant switch back to compiz unless I restart X.

glade@Mean-Machine:~$ compiz --replace &

Once I restart X, it works normally again. I have tried Compiz fusion icon and Compiz-switch. Neither of them work for me.
Any ideas?

Shouldn't xgl be running with that gpu? Is it usually running when compiz is?

The previous output was after I once fired metacity --replace.
Now this one I fired with compiz running already. I still have compiz after this, (since I have'nt switched to metacity yet, as mentioned above)

I think you may have metacity's composite manager enabled. The compiz-check script i have attached should help you fix the issue. You must run it with metacity enabled.

Bravo!
The problem was simple enough! Metacity was running in background and compiz wasn't able to run with metacity running. I have to terminate metacity to start compiz (Which the --replace should do, but it isn't doing). So I simply do a killall metacity before firing compiz --replace again
Thanks for the script. Very useful script indeed!
