I am having trouble running Ubuntu on a custom made desktop (some specs below). The problem is that at a certain point my monitor shuts off and gives me the message:
The current input timing is not supported by the monitor, Please change your input timing to be 1920x1200@60Hz
Initially I was having this problem during installation, so when the first purple screen would come up I hit the down arrow and set nomodeset and added "vga=0x14d" to the end of the command. This allowed me to continue without getting the above error on my monitor. Once installation was complete I edited /etc/default/grub to include the line:
Then I entered:
And restarted the computer. Now when I get to the Grub screen, everything is fine but after the that I again run into the input timing error. I have tried various permutations and combinations in the edit screen but I can't seem to set the resolution properly to actually see Ubuntu once it has started up.
Ubuntu version: 16.04
Motherboard: Asus X99-E
GPU: Nvidia GTX 1080
Monitor: Dell U2412M
EDIT: The motherboard does not have an integrated graphics card.
EDIT2: I tried following the answer for Graphics issues after/while installing Ubuntu 16.04 with NVIDIA graphics, however setting nouveau.modeset=0 at the end of the line that begins with "linux" does not work, I still get the input timing error above and if I cannot boot into Ubuntu then I am unable to install drivers.
