Wanted to add a couple of working cards:
XFX GeForce 7600GT PCIe x16Works with everything I have thrown at it UI2, alpha blending no problem
Works now in 8.10 and 10.04 out of the box.
256MB DDR3, SLI available if you're that brave
PCIe slot
Was extremely cheap 4 years ago so probably available as wholesale lots now...
Able to support twin x screens with small tweeks to xorg.conf. Used as a media director in the living room or the bedroom.
- Display is mirrored to both DVI outputs so one DVI out to bedroom 23" monitor, one DVI out to DVI-to-HDMI cable connected to 60" Sharp Plasma
- Doing 1080p to both displays though the monitor DVI port is connected to DVI-to-VGA adapter to make it through my VGA KVM switch.
Nvidia GeForce 6600 AGP x8
1 VGA, 1 DVI (I think there was an S-video)
AGP slot, 256MB
Worked with Medium settings in 1004
Installed on loan from roommate to test a troublesome Media Director = Didn't get to play much
Failed to setup X on first MD boot. I ssh'ed in and poked my nose around without altering anything. Did a standard reboot and it booted back up to av wizard.
Large card for a MD and required a molex power connector.
Still to test
An older 128MB Radeon AGP
The always lovely Intel 82845G (onboard)
Homemade AGP riser for htpc cases or crazy case mods I like to mess with
USB video - I am getting one of these with hopes of adding new options for MDs, will stick it in a laptop if it fails horribly
