Add and save custom resolution on KDE

designator · 08-25-2017, 01:59 PM

I'm stuck working on a 15" MBP with an idiotic 4K display running at 2880x1800 which is completely unusable. Thankfully it scales well to 1920x1200. Problem is it is not an option when selecting the resolution through System Settings in KDE.

I can force the resolution by running the following script:

Code:

xrandr --newmode 1920x1200_60.00 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync
xrandr --addmode eDP-1 1920x1200_60.00
xrandr --output eDP-1 --mode 1920x1200_60.00

It changes the resolution until the next restart. I added this script to KDE startup, but it doesn't run reliably and when it does work it causes screen to blink/blank during login which is ugly.

Is there any way to force the laptop screen to permanently stay @ 1920x1200 whenever X starts?

Thanks.

not all fonts scale well
seeing as this is a laptop ( no 3d card )
is this a dual intel/nvidia bumblebee ?
or what

what is the default native resolution

also WHAT is this unknown OS that is running kde ?
systemV VS. SystemD might come into play

is it suse tumbleweed ?
then use "kickoff / Applications / settings / configure desktop "
and set it there

Knowing what tpye of graphic are is installed would help to guide you in the right direction.

Only Intel video card. OpenSUSE Tumbleweed like it says in my profile.
Default native resolution is in the original message: 2880x1800.
Also, like I said in the original message, the resolution I want doesn't show up in the configure desktop applet.

If this is Plasma then you could look in '/home/<user>/.kde/share/config/startupconfig' for krandrrc_display_startupcommands=. There you should be able to add your resolution you want. I haven't tried this so I'm not 100% sure this will work.

you can check out system settings-->display and monitor-->scale display...YMMV

That only scales certain GUI elements and doesn't help with other stuff like applications still displaying text which is way too small to read. Thanks for suggestion though.

You could try creating an xorg.conf file, then modifying it accordingly.

X has become so stable that an xorg.conf file is no longer present by default.
