## Submitted by Daniel Pielmeier Assigned to **Xfce Bug Triage** **[Link to original bug (#8841)](https://bugzilla.xfce.org/show_bug.cgi?id=8841)** ## Description I am experiencing the same problem like here: http://mail.xfce.org/pipermail/xfce/2012-March/030209.html. When I try to start XFCE from the xdm log in screen it always switches back to the screen and does not log me in. When I start it from startx I am able to log in like normal. I get the same error message in .xsession-errors like the reporter from the mailing list: /usr/bin/startxfce4: X server already running on display :0 XDM authorization key matches an existing client!xfce4-session: Can not open display: . Type 'xfce4-session --help' for usage. If I can provide more information jut ask. Version: 4.10.0 ### See also * http://bugs.gentoo.org/show_bug.cgi?id=420745
