My system specs :
- Intel i7-8700k (Coffe-lake)
- Mother board : ROG(Maximus X Hero)
- OS :Ubuntu-Gnome 16.04
I booted my new PC with Ubutnu-Gnome 16.04, after installation the screen resolution is 1024x768(4:3), and screen is shown
Unknown Display. I haven't installed anything on my new OS. My Monitor-CPU connecting Cable is an DP (Pin Cable).
I have tried with "Force create new resolution":
cvt 1366 768 60
xrandr --newmode "< >"
Then an error occurs:
xrandr : Failed to get size of gamma for output default
I want perfect resolution to be fit for my desktop screen.
Can Anyone help me on this problem?
