XRANDR

Imel sem problem, da se ni pokazala prava resolucija za sosednji ekran, če sem ga priključil preko USB-C Multi-hub-a. Rešilo me je, da sem najprej:

xrandr --auto
xrandr

nato je bila resolucija tu:

ADD MODE

Kako dodoamo novo resolucijo zaslona

cvt 1920 1080 60

1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz

Modeline “1920x1080_60.00” 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

Nato skopiras zadnjo vrstico izhoda in jo uporabiš v naslednjem ukazu

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

in ta mode dodaš monutorju, ki mu ta mode manjka

xrandr --addmode DP1 1920x1080_60.00

preverimo če je mode na spisku možnosti

xrandr

in vključimo monitor s to resolucijo

xrandr --output DP1 --mode 1920x1080_60.00 --pos 1920x0

Problem 2: Dimenzije monitorja niso bile pravilno odčitane

Namesto dimenzij 477 mm x 268 mm so se dimenzije monitorja nastavile na 160 x 90 memory To sem popravil tako, da sem v datoteko /etc/X11/xorg.conf.d/90-monitor.conf nastavil pravilno velikost zaslona:

Section "Monitor"
    Option    "UseEdidDpi"    "false"
    Identifier             "DP-1-8"
    DisplaySize             576 267
