I'm a very happy compiz user, but I have to choose between two minor problems:
One: I can't configure compiz with gset-compiz, when I use this startscript:
DISPLAY=:1 LD_PRELOAD=/usr/share/fglrx/diversions/libGL.so.1.2 compiz --replace decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher transset trailfocus water &
Everything works, but the wobbling is pretty extreme (that's what I'd need gset-compiz for)
Second: When I watch fullscreen videos, I get a line from the top left to the bottom right corner of the screen, it only appears when something is moving, + performence problems. Gset-compiz works though:
## from Ubunutu - Wiki:
compiz --replace gconf &
## from blog
# killall gnome-window-decorator
# gnome-window-decorator &
# compiz --replace gconf &
cgwd seems to do the same as gnome-window-decorator. - same result.
Mind that my scripting - ability is limited to copy and paste.
And while you're at it...
What's the difference in saving a script in /usr/bin/ opposed to /usr/local/bin/ ?
apparently it has something to do with gconf. That's why it works if I load all the plugins "manually", and That's why gset-compiz won't work.
I have no idea what I could have set in gconf that screws with the video display. Maybe I'll have to reset.
(If someone knows how to reset gconf, that would be good too
On the first page of gset-compiz there's an option "unredirect fullscreen" I unchecked it - now it works.
Just out of curiosity, if anyone knows what it does...
