Compiz w/ dual-head VGA+TV-Out

[mitchell2345]

I have worked on getting compiz to work with a dual-head FC6 installation forever. After many changes and hours of work i believe its a video card or a compiz limitation.

Using a nVidia 6600GT w/128mb
VGA - 1024x1280
TV-OUT - Component 720P

I can get compiz to work with only the VGA on but not with the TV out too.

refer to this tread on fedoraforum.org for detailed chnages

Am I correct? or am I doing something wrong?

Thanks,
Mitchell

Looking on your other post I see that at one point you had this error.

[root@mitchell2345 mitchell]# compiz --replace
compiz: SmcOpenConnection failed: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Segmentation fault

You seem to be trying to run compiz as root which is wrong, compiz should be run as your normal user. If you still get the smc errors then you can try launching compiz with --sm-disable

Also you will need the --use-cow and --indirect-rendering options if you are using the nVidia beta driver and launching compiz directly.

same things using those options...

[mitchell@mitchell2345 ~]$ compiz

The last 2 are interesting since it shouldnt segfault. They seem like the right command (although the sm-disabled might not be needed now you are running as your user)

It is a bug in compiz which should be reported, are you able to get a backtrace for it? (try running with --use-cow --indirect-rendering --replace)

[mitchell2345]

same thing sef fault. How do i report a bug?

[mitchell@mitchell2345 ~]$ compiz --use-cow --indirect-rendering --replace
Segmentation fault
[mitchell@mitchell2345 ~]$

You should report it on the mailing list to see if anyone there can help you.

By the way, you should actually start with gconf at the end, but that shouldnt be causing the crashing.
