x11docker ToDo notes

Current

report: Xwayland -rootless -decorate: Misleading geometry error message report: weston Xwayland display number report?: --nxagent: -ac -auth bug --clipboard: use wl-paste --watch if possible --satellite version check, waiting for release yet --weston=X: Do not terminate if Xwayland terminates? --xpra firefox: black window on first firefox startup --runtime=sysbox --xorg --xc fails --display: Newwaylandnumber screen capture in x11docker/check profile.d: check for xrdp #554 bug NVIDIA: --xc=force --gpu --xorg/--weston (nvidia): black screen after terminating, no tty switch possible. workaround yet: --backend=podman --hostdisplay fails > glxgears: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /x11docker/XlibNoSHM.so) further centralize argument checks

Old issues to check

  • use ~/.Xauthority in general? issues with --retain setups, need to check images for HOME and USER etc.
  • --remove: give note about not removed files in ~./config/x11docker and /etc/x11docker
  • --update: Check if installs not into /usr/bin or /usr/local/bin. Do not install other files then.
  • bug: ssh: --hostdisplay fails
  • bug: setting XAUTHORITY with systemctl
  • --xc --xorg: MIT-SHM fails
  • --xc --xorg rootless fails
  • check empty XDG_RUNTIME_DIR e.g. with --user, --hostuser
  • --interactive --init=runit|openrc|sysvinit: no job control in shell
  • --interactive fails now with old systemd versions. (wontfix, not important enough)
  • --init=openrc|runit: elogind fails
  • check elogind with cgroupv2. maybe drop --sharecgroup and set up in container only
  • docker-for-win: DOS newline mess in error() #219.
  • docker-for-win: Double entries in log.
  • --init=systemd: check systemd warnings on x11docker services
  • --printer: regard host environment variable CUPS_SERVER. Maybe already done by lpadmin.
  • myrealpath(): If realpath is missing, the path argument is returned without resolving.
  • --interactive not possible without winpty in WSL and Cygwin
  • --interactive --enforce-i fails. Issue is subshell containershell & in main, would work without it.
  • --group-add: gid 101 for both possible: messagebus and systemd-journal, works nonetheless.
  • --wayland --user: wayland socket access denied due to XDG_RUNTIME_DIR file access permissions

Nice to check

  • check all --init= in all backends rootful and rootless.
    • checked:
      • rootful docker: all
      • rootless podman: systemd, openrc
      • rootful podman: openrc
      • rootless nerdctl: openrc
      • rootful nerdctl: openrc
  • --user: Check in all rootless modes, maybe disallow except for --user=root.
  • --user=root --home in rootless docker and nerdctl: Set up HOME in host user ~/x11docker?
  • --backend=podman rootless: disallow --home for different --user.

3rd party bugs

Improvements

  • --cleanup: avoid hardcoded paths
  • x11docker/check: palinopsia: check video RAM size with glxinfo, adjust requested RAM size.
  • further checks of /etc/pam.d
  • further checks of multimonitor behaviour
  • --init=s6-overlay: find better solution than sleep loop for empty CMD
  • --init=s6-overlay: check possible shutdown routine for timetosaygoodbye
  • --init=s6-overlay: closer check of needed capabilities
  • fedora: SElinux issue: --security-opt label=type:container_runtime_t: need more restrictive setting to just allow socket access. https://unix.stackexchange.com/questions/386767/selinux-and-docker-allow-access-to-x-unix-socket-in-tmp-x11-unix
