One of my daily companions is sway. sway is a tiling window manager that best meets my daily needs https://github.com/swaywm.A really good introduction to the world of Tiling Window Managers is this video:

Unfortunately, I have an Nvidia graphics card installed in my current notebook. Until some time ago, Nvidia only had a proprietary driver for Linux. Now there is better support thanks to https://github.com/NVIDIA/open-gpu-kernel-modules

To get the nvidia working with sway i have to setup some Environment-Variables. I use Archlinux and there is a nice way under arch to do that.

Vars

As root on a archlinux open /etc/environment and add the needed vars:

 #
 # This file is parsed by pam_env module
 #
 # Syntax: simple "KEY=VAL" pairs on separate lines
 #
 # working well
 _JAVA_AWT_WM_NONREPAINTING=1
 XDG_SESSION_TYPE=wayland
 XDG_CURRENT_DESKTOP=sway
 XDG_SESSION_DESKTOP=sway
 WLR_NO_HARDWARE_CURSORS=1
 QT_QPA_PLATFORMTHEME=wayland;xcb
 QT_WAYLAND_DISABLE_WINDOWDECORATION=1
 # Mozilla Stuff
 MOZ_ENABLE_WAYLAND=1
 MOZ_USE_XINPUT2=1
 # MOZ_DISABLE_RDD_SANDBOX=1
 # vaapi tweaks
 # NVD_BACKEND=direct
 # sway stuff 
 # ENABLE_VKBASALT=1
 # If the following is enabled then Firefox vaapi is broken (video playback crashes and PDF Preview broken) see /usr/bin/firefox
 GBM_BACKEND=nvidia-drm
 # WLR_RENDERER=vulkan
  # __GLX_VENDOR_LIBRARY_NAME=nvidia
  # __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json
  # LIBVA_DRIVER_NAME=iHD

 #testen mit usb4
 #WLR_DRM_NO_ATOMIC=1

Some vars are disabled because they are not needed on my system or they have some issues with my card.

Firefox crashes sometimes

If you have issues with Firefox then try this hack

awk 'NR==2 {print "GBM_BACKEND=iHD"}7' /usr/bin/firefox
