--- Comment #2 from Matthias Nagel matthias.h.nagel@gmail.com --- @Michel: How and where do I set the environment variable GALLIUM_DDEBUG="pipelined 2000" such that it is passed to the execution environment of the Xorg process or compositor? I use systemd as my init system and the active service file is sddm.service. Presumably, I need to modify some unit files but offhand I do not have an idea which one.
