compiz dual X display problems

[rybu]

Hi,

I'm having trouble getting compiz to work properly with two X displays. Without compiz running, my two X displays work perfectly. With compiz running, let me list some of the most basic problems:

1) On the second display, the window borders do not appear. The 1st display functions perfectly.

2) On the 2nd display, the water effect hangs X. Water effect works perfectly on the 1st display.

3) On the 2nd display, "expo" does not understand the screen dimensions. My 2nd display is 1600x1200, the 1st is 1920x1200. "expo" does not centre properly on the 2nd display, as if it thinks it is 1920x1200.

4) On the 2nd display, fonts are blurry with Compiz enabled. Disabled, all is fine. All is fine on the 1st display regardless of whether or not Compiz is enabled.


Here's my abbreviated xdpyinfo output:

Anyone know if this is a misconfiguration problem, or perhaps it's a bug in... something?

I'm running Ubuntu 7.10 on a Thinkpad t61p with an NVIDIA quadro FX570M graphics card, running the latest "nvidia" driver: NVIDIA-Linux-x86_64-100.14.19-pkg2.run

xorg.conf is configured by the nvidia-settings app:

hey rybu,
I dont have a solution off hand , but I wanted to ask if you tried twinview since you have an nvidia card.

Yeah, I tried twinview but I didn't really like it. Seperate x displays allow me more flexibility. I don't need to move windows to the 2nd display as I mostly use the 2nd display for keeping track of more long-term projects.

Yeah, I have the same problem as the rybu. At least, one of the problems. No Window Borders on windows for second display. Pretty big problem, because I'm not able to click & drag or move my windows.

I'm running the nvidia restricted driver and Gutsy Gibbon. When I disable compiz fusion, everything is fine. When I enable it, second monitor has issues.

It's odd, I go into the new Gnome Compiz Manager and see options for screen0 and screen1, but making changes for one, makes changes on the other. I go into gconf-editor and only see options for allscreens and screen0. There is no screen1 section and I'm not sure how to create on there either.

Compiz has a command so that you can move and resize the window, even if there's no borders. If the compiz manager you'll find the keys... To move a window, press <ALT>, your left mouse button and drag.

There's a similar feature for resizing, but I forget the keystrokes. Poke around and you should find them.

I find the problems on the 2nd display destabilize my system. Some compiz effect can kill X -- like the water effect. So I keep compiz disabled for now.

I had a similar problem. See my reply here (http://forum.compiz-fusion.org/showpost.php?p=32615&postcount=2). Try running emerald from a term spawned from that screen (or manually set DISPLAY env variable.) Run it as whatever user you are logged into X as.
