I found out that the script --- #! /bin/sh if test -z "${XDG_RUNTIME_DIR}"; then export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir if ! test -d "${XDG_RUNTIME_DIR}"; then mkdir "${XDG_RUNTIME_DIR}" chmod 0700 "${XDG_RUNTIME_DIR}" fi fi --- doesn't work. Are there bashisms in it? I wanted to make it `#! /bin/bash`, but the shell claimed that being unknown. I *thought* I checked with `echo $XDG_RUNTIME_DIR` before and the clear error message about it did go away, but when I set XDG_RUNTIME_DIR manually and confirmed its existence and mode today, suddenly I got, with weston-launch NOT in setuid: --- thorwil@charly ~$ export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir thorwil@charly ~$ echo $XDG_RUNTIME_DIR /tmp/1000-runtime-dir thorwil@charly ~$ mkdir "${XDG_RUNTIME_DIR}" mkdir: cannot create directory '/tmp/1000-runtime-dir': File exists thorwil@charly ~$ chmod 0700 "${XDG_RUNTIME_DIR}" thorwil@charly ~$ weston-launch Date: 2018-03-12 CET [21:03:08.884] weston 3.0.0 http://wayland.freedesktop.org Bug reports to: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=3.0.0 Build: unknown (not built from git or tarball) [21:03:08.884] Command line: /gnu/store/rm8q589057mxqlld1d2zwh5gi9y6cln2-weston-3.0.0/bin/weston [21:03:08.884] OS: Linux, 4.15.8-gnu, #1 SMP 1, x86_64 [21:03:08.884] Using config file '/home/thorwil/.config/weston.ini' [21:03:08.885] Output repaint window is 7 ms maximum.

Attached (hope it works on this list). `strace weston-launch &> starce_weston-launch.txt` does not contain "tmp", "runtime" or "XDG", but: "Error opening device /dev/input/eventX: Permission denied" for X in [0-9].
