I can see the mouse on the other screen but I have no desktop.


I cant seem to find a fix for it, not due to lack of trying I assure you.

Your using an NVIDIA, right? Can you slide a window to the other monitor? When you run
gksu nvidia-settings On X server info does it say what driver you are using? Post some screeners of the display configuration tab I'll work you through it.

When I booted up this morning the second screen came up when as soon as a logged in and is working fine now.

However, now my desktop effects will not enable, I get this error message:


The Composite extension is not available.


then this happens:


:~$ compiz
Checking for Xgl: not present.
xset q doesn't reveal the location of the log file. Using fallback /var/log/Xorg.0.log
Detected PCI ID for VGA:
Checking for texture_from_pixmap: present.
Checking for non power of two support: present.
Checking for Composite extension: not present.
aborting and using fallback: /usr/bin/metacity
Xlib: extension "RANDR" missing on display ":0.0".


whats up with that?

Would the resolution of ether monitor make a difference?

maybe this will help tho its just my guess.

both monitors need to be set at the same resolution and if one monitor still stays blank try dropping both to a lower resolution and see if that works.

Did you save the new settings to your Xorg File, then rebooting?

Xinerama or Twinview?

Xinerama does not support compiz. Twinview does.

aww, for real!?!

that not cool :(

K, I guess that's what the problem is, thanks for clarifying that for me.

Just wondering... why aren't you using Twinview? It seems to be the more mature of the two.

Whereas Xinerama can't run compiz, Twinview can't rotate the screen... so unless that's your problem, I don't see why you shouldn't use it :)
