Hey all,
I'm trying to get a single desktop running, and I've been beating my head against this for months now. Nothing I've tried has worked, so I'm turning to the experts. Dual-head on one card is fine.
2 x Radeon HD 5700
4 x Acer P241W (24", 1920x1200, all on DVI)
xorg-server 1.7.6
kernel 2.6.34
Gentoo
I did have it (semi-)working with Xinerama a few months back, but then X upgrades, kernel gets bumped, ATI drivers go up... So here we are. I know the hardware's fine - just put on Windows 7, and it took about 25 seconds to get all four screens lit and configured.
amdcccle Display Manager shows two screens (the working ones), and a card icon with "[Unknown Display] Unknown adapter." lspci has
02:00.0 VGA compatible controller: ATI Technologies Inc Device 68b8
03:00.0 VGA compatible controller: ATI Technologies Inc Device 68b8
so they're both seen there. aticonfig --lsa gives
* 0. 02:00.0 ATI Radeon HD 5700 Series
1. 03:00.0 ATI Radeon HD 5700 Series
Just to add a wrinkle, my setup is three screens across, and one above the middle. Tetris piece, kinda. Card one is screens 1 & 2; card two is screens 3 & 4.
Not sure where to go from here. I'd paste my xorg.conf, but two screens are working fine, so that won't be much help. Perfectly happy to try/paste anything though.
Thanks!
