[SOLVED] Setting refresh rate

Hi all,

Yesterday I've installed Arch on my machine. The installation went well and I understood what was happening. A big change from Ubuntu!

Anyway, I installed all my drivers and everything seems to work. I do have an issue with setting the refresh rate of my monitor. The system defaults to 60Hz at 1080p, but my monitor is a 144Hz monitor.

I know the refresh rate works, because if I execute 'arandr -r 144' the screen switches to 144Hz. However, after a reboot it's back at 60Hz.

I followed this guide in the wiki:
https://wiki.archlinux.org/index.php/Xo … conf_files

I created a /etc/X11/xorg.conf.d/10-monitor.conf file with the following contents:

Section "Monitor"
    Identifier             "Monitor0"
EndSection

Section "Device"
    Identifier             "Device0"
    Driver                 "amdgpu" #Choose the driver used for this monitor
EndSection

Section "Screen"
    Identifier             "Screen0"  #Collapse Monitor and Device section to Screen section
    Device                 "Device0"
    Monitor                "Monitor0"
    DefaultDepth           24 #Choose the depth (16||24)
    SubSection             "Display"
        Depth              24
        Modes              "1920x1800_144.00" #Choose the resolution
    EndSubSection
EndSection

After this, I can't login. After entering my password, the screen becomes black and then reverts to the login screen.

Any ideas how I can handle this issue? Thanks!

@G-Force
You copied example code, to be filled in by your own values, I very much doubt that your monitor is detected as Monitor0.Also follow the posted links for the randr way of configuring X. Also check your X log likely located in ~/.local/share/Xorg.0.log with the free drivers.

Whoops, that's a little mistake. I am not on my desktop right now so I took the example code like I did yesterday and filled it in like I did yesterday. I can assure you, this mistake is not present on my desktop.

I will take a look at this documentation tonight. Thanks!

I was under the assumption these values didn't really matter. I will take a look at it tonight and will report back, thanks!

EDIT:
It works! Thanks guys, the links for Xrandr were great. I have no idea why I missed it, because I have read parts of the wiki page before.

And V1del, the monitor was DisplayPort-0.
