I tried this before I wrote to this list. It does not work. No 'normal' users can create these files from /etc/X11/Xclients. But after gnome starts up, they can create these files. If I login with a normal user and I try to re-run /etc/X11/Xclients then the files gets created, and finally I get an error message telling that gnome is already running. > If that fails then you can try logging them with syslog. How can I do that from Python? :-) I tried this: from syslog import * syslog(|LOG_INFO | LOG_USER, 'test') No exception raised but I found nothing under /var/log.| > > Are you sure that if say the file() fails, that a window manager won't > start anyway? You can test that by making the filename something > clearly non-existent. To your request, I changed the ddir variable to '/nonexistent', and gnome was started! So you found the problem! Thanks! :-) It was that gdm started /usr/local/etc/gdm/Xsession. That script started /etc/X11/Xclients but ONLY for user gandalf. It is because I selected 'use system default session' in gdm before logging in. It was months ago, and I forgot it. Other users were using the default gnome session, e.g. they were NOT executing the Xclients script. Thank you again! Laszlo
