Linux defaults to motherboard VGA instead of using GTX 8800
by bulletgirl22 from LinuxQuestions.org on (#5PZB1)
I've been using my motherboard's VGA output for my display but its way too slow, to the point that I can't stream video in greater than 720p. So I got a GTX 8800. I can use it to view the BIOS and it displays Grub fine. But when I try to boot into linux (Debian 10) it switches the output to the motherboard's VGA. It displays two error messages on the monitor from the GPU with a blinking keyboard cursor:
[ 3.319654] ERST: Failed to get Error Log Address Range.
[ 3.427483] APEI: Can not request [mem 0xcff7d550-0xcff7d5a3] for APEI BERT registers
These can be found in dmesg as well, but I don't think they're related to the problem because these same errors present even when the GPU is not installed.
When the GPU is not installed I can use startx to start KDE, but if the GPU is installed I get an error from Xorg. Getting the DE to work is also important but I suppose that for right now I really just want to know why its refusing to use by GPU even for a basic terminal.
