Xfce / Xrandr cannot recognize proper resolution and refresh rate
« Last post by GrandGamer on 10. October 2018, 01:47:09 »
I have a 2k 144Hz Samsung FreeSync monitor. When I was using HDMI, I had proper resolution but the Refresh Rate was only 60 Hz. When I switched to DisplayPort (monitor's included cable), xrandr only recognizes up to 1080p60hz.
I use 2 monitors, the second one is a 1080p 60hz monitor. I am on an i7 3930k with AMD RX 460 gpu with AMDGPU driver. Keep in mind that the proper resolution is reported in Xorg logs from the monitor EDID.
Also note that Xubuntu on a live USB sets the proper resolution and refresh rate.

EDIT: I should also add that in HDMI mode, Manjaro not only doesn't recognize 144Hz but it also recognizes 4k resolution which isn't supported by the monitor.

Newbie Corner / Re: Screen Resolution Problem (800x600 only)

Am happy to report that reading the above wiki resolved the issue. I added the following lines to /etc/X11/xorg.conf.d/20-gpudriver.conf as outlined on the wiki under xorg driver :

Section "Device"
    Identifier "Intel GMA3600"
    Driver     "modesetting"
EndSection

On reboot the resolution had changed to 1024x600 and even better the brightness buttons now work. Thanks for the help Eugen-b.
It worked ! Thanks :) (N3050 processor 2018)

The latest patches from Intel are problematic at best:
