dotfiles

[openSUSE] configuration tips outside of per-user dotfiles:

Prevent SDDM scaling if it shouldn't

create /etc/sddm.conf.d/dpi.conf with the following content:

[X11]
ServerArguments=-dpi 96

Hide kernel warnings on tty after boot

sudo rm /usr/lib/systemd/system/[email protected]/noclear.conf

Scale 4k screen that doesn't accept a lower resolution

Add to /etc/X11/xorg.conf.d/50-screen.conf:

Section "Screen"
  Identifier "Default Screen"
  Device "Default Device"
  Monitor "Default Monitor"
  Option "metamodes" "DP-4: nvidia-auto-select +0+0 {viewportin=1920x1080, ForceCompositionPipeline=On}, DP-3.1: nvidia-auto-select +1920+0 {ForceCompositionPipeline=On}, DP-3.2: nvidia-auto-select +3840+0 {ForceCompositionPipeline=On}"

EndSection

Scale lightdm on 4k screen

Create '/etc/lightdm/lightdm.conf'

[SeatDefaults]
greeter-setup-script=/etc/profile.d/lightdm.sh
session-setup-script=/etc/profile.d/lightdm.sh

and the respective /etc/profile.d/lightdm.sh:

#! /bin/sh
if [ ! -z "$DISPLAY" ]; then
        /usr/bin/xrandr --output DP-4 --scale 0.5x0.5
fi

Don't forget to chmod +x that one!

Install ruby gems

By default openSUSE messes with the name of installed gems, Use gem install --no-format-executable to prevent that. Also, --user-install can be helpful to install to a directory in the user's home.

Fixing Firefox right-click menu on bspwm:

Apparently window borders fuck with the mouse positioning. This snipped in userChrome is a workaround:

#contentAreaContextMenu {
    margin: 10px 0 0 10px
}

Shut up the sound card beeping

Soundcard somehow beeps audibly when on powersave. Adding the following line to /etc/modprobe.d/50-alsa.conf shuts it up:

options snd-hda-intel power_save=0

feh crashing because of missing fonts

Packaging bug, but whatever, just link stuff to where feh expects it:

sudo ln -s /usr/share/feh/ /usr/local/share

Fix kwin screen tearing on nvidia with triple buffering

Create a file called /etc/profile.d/kwin.sh with the following:

#!/bin/sh
export KWIN_TRIPLE_BUFFER=1
