can't enable visual effects after adding new PCI card

[zpletan]

Binary package hint: gnome-control-center

I am using Ubuntu Karmic (9.10) with gnome-control-center 2.28.1-0ubuntu1.

I have a graphics adapter, PCIID 8086:2562, which compiz blacklists (for good reason). However, I recently installed a new PCI graphics card,while leaving the old one in because it is part of the motherboard. I also installed the proprietary NVIDIA drivers for my new graphics card.

I commented out the PCI blacklist in /usr/bin/compiz, and compiz (by running compiz --replace) runs fine. I then decided that I would not like this to become re-commented whenever compiz gets updated, so I reinstalled compiz, and added the line "SKIP_CHECKS=yes" to ~/.config/compiz/compiz-manager. Compiz still runs fine (checked by running metacity --replace and then compiz --replace).

And now, the main point - I go to System->Preferences->Appearance and set Visual Effects to None. Then I set it back to Custom (I have installed ccsm-simple), and a window pops up searching for drivers, and then I am informed that Desktop effects could not be enabled. When I restart and then log in, my window manager is still set to metacity, forcing me to run compiz --replace.

How can I get gnome-appearance-properties to let me enable Visual Effects/compiz?

In the meantime, I have discovered a workaround to this issue. I was experimenting with gnome-shell, and I set it as my default WM via the GConf key /desktop/gnome/session/required_components/windowmanager. After getting tired of Gnome-shell, I wanted to re-enable compiz, and discovered, to my delight, that setting this key to "compiz" starts compiz up at login time.

Still present on Lucid.

Never mind - it's fixed. (I could have *sworn* I tested.)
