Hi there,
As you know Gigabyte points users who want to run a Linux based system to other sources for drivers.
I am not too familiar with Linux although I do play with Ubuntu. I am running a GA-790XTA-UD4 with a Phenom ii 1090T, 8Gb of Corsair Dominator RAM and a Sapphire 4850X2, a Delta 1010 Soundcard and 2 LG Flatron Monitors
The only problems I have had in getting Ubuntu 10.4 to run on my Rig has been with the Marvell SATA3 ports not being recognised. I have to admit to not pursuing the problem too far as I run Windows 7 and that has its own issues with the same ports. Even when set to Native IDE Ubuntu can not find them. Everything else seems to work OK under Ubuntu and, as there are enough SATA 2 ports on this board, it's not a problem for me but could be if you were looking to use all of the SATA ports. I have all of my SATA Ports set to Native IDE.
Apart from the ATI Drivers for my 4850 and the drivers for the Delta 1010 , everything else was automatically installed, but there were no issues getting the ATI or Drivers for the soundcard.
I have made no major changes to the BIOS other than what I would normally do, but it works fine with Optimized Defaults. I normally disable the on-board sound, because of the Delta 1010, and I have disabled the Serial Port and e-SATA controllers as I do not use them. I also have turned of the CPU Smart Fan control and the AMD K8 Cool&Quiet Control as I run my CPU Cooler fans directly from the PSU
