VisionTek Radeon™ 7750 SFF 1GB x16 PCIe Graphics Card (90054

[danbeaver]

Bought this card recently to take advantage of the Warp3d/miniGL in OS4.1FE on my X1000, and when I booted Ubuntu 12.04 with the 3.18 kernel I had no monitor signal; now this card has a DVI and HDMI output connector, and on research the card has dual monitor support. So when I switched cables, it seems the OS4 claimed one and the Ubuntu claimed the other output.

Is this the standard, or is it unusual?

Please add 'blacklist snd-hda-codec-hdmi' to /etc/modprobe.d/blacklist.conf. After that reboot your X1000. I know it's HDMI sound but maybe it could help to fix the Xorg problem.

Thanks!

I'll give it a try.

Sorry, that didn't work; it still starts out on the DVI port in the early boot and then after the Ubuntu "splash screen" dots, switches to the HDMI. Both go into a MonoPrice HDMI switch box and I just switch between the two with a remote -- so not too much of problem. Just strikes me as odd behavior.

Xorg works If I understand it correctly. You could try to configure your own xorg.conf to set up the ports. Boot into recovery mode and select Root Shell. Then run: X -configure. Then: cp /root/xorg.conf.new /etc/X11/xorg.

Radeon HD6870 xorg.conf with two DVI ports.
