View Full Version : [ubuntu] nVidia dual x-screens buggy with compiz

**NEWBIE**

Running Lucid Lynx, dual cards with one monitor (and one x-screen) each. Runs fine with visual effects turned off (with or without xinerama; twinview is unavailable). Xinerama, I've found, has been a problem with compiz. No big deal, I don't mind running two different desktops with 4 workspaces on each. When effects are enabled, with compiz running, the secondary monitor shows the wallpaper and mouse with no taskbars, key function, or desktop items. When I try the hotkeys for compiz, the mouse icon disappears. I have tried to disable nautilus (the result was that it just didn't draw the mounted drive icons), and using KDE instead of gnome (have KDE installed, but not functioning in the login screen). Latest closed source driver installed and desktop effects work fine on both monitors without compiz effects enabled.

Just switched from windows last week, so I know I'm missing something trivial here...
