Hi,
I’m running Manjaro with Gnome on my Dell E6540 with internal graphic and Radeon HD 8790M. I tried everything from google, but I still cannot set proper (2560x1920) resolution on my external monitor. I tried everything related to xrandr and even adding the mode to the grub configuration via “video” param.
