Seriously, what a terrible idea. The magic file is /usr/share/gnome-session/sessions/gdm-shell.session and the magic line is IsRunnableHelper. It's actually run by *gnome-session*, not gdm. And if that line fails (due to issues in kernel DRM or the graphics stack or your slow disk), or takes longer than 3000ms, then you get the fallback session instead of the fancy one. IsRunnableHelper=bash -c 'gnome-shell --help | grep -q gdm-mode && /usr/libexec/gnome-session-check-accelerated' --- /* See https://bugzilla.gnome.org/show_bug.cgi?id=641992 for discussion */ #define GSM_RUNNABLE_HELPER_TIMEOUT 3000 /* ms */ --- Dan -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
