Hi, I've got a Lenovo X250 with Manjaro i3 with 4.4.210-1-MANJARO kernel. At home, I use a docking station and my laptop is FHD, and my only external monitor too. Everything is fine.
At school, I used a videoprojector with FHD capabilities. Arandr allowed me to set the projector's resolution to FHD / 1920x1080 but a few days ago, it stopped working : I can only output 1024x768 to the videoprojector. Would you have any suggestion ?
I tried to (just follow the xrandr Arch documentation step by step):
- get a Modeline using cvt ;
- add a new "mode" using xrandr ;
- output that to the projector,
But it failed. Did I miss something ?
