[Bug 231697] Re: Composite extension not working with dual screens using Xinerama

 

I have the same problems as well.

I have dual GeForce 9800 GTX+ cards running three monitors with SLI
enabled.  This is working very well.  I was trying to enable the extra
visual effects and get the error:...Well sometimes I get the error and
sometimes it just locks up the Appearance Preferences window like just
now...OK... I get ther error: The Composite extension is not available.
And when you click OK on the dialogue box  nothing happens, you have to
click the X on the window to make the dialogue box go away.

I also have the issue when I cross from one screen to the other the
mouse will continue to the next screen, but it will leave a mouse
pointer on the previous screen at the point where the mouse crossed
over.

I am running  Ubuntu 9.04 Jaunty Jackalope with the nVidia 180 driver.
I had the three monitor setup with 8.10/Intrepid and it didn't have the
mouse pointer issue.

If I disable Xinerama then I have a task bar across every screen and I
can't move a window from one screen to the other, but even worse when I
open an application from one of the other screens it will put them all
on the primary screen which renders my other two monitors useless.

I just wanted some eye candy, but I will just have to keep waiting.

Hardware:
02:00.0 VGA compatible controller: nVidia Corporation GeForce 9800 GTX+ (rev a2)
04:00.0 VGA compatible controller: nVidia Corporation GeForce 9800 GTX+ (rev a2)
