Hi, for a long time i didn't use a Display Manager but now i need one but it always failed to login. KDM tolds me: A critical error occurred. Please look at KDM's logfile(s) for more information or contact your system administrator. In the kdm.log there is nothing spezial: (==) Log file: "/var/log/Xorg.0.log", Time: Wed Jan 24 10:27:01 2007 (==) Using config file: "/etc/X11/xorg.conf" xkb_keycodes { include "xfree86+aliases(qwertz)" }; xkb_types { include "complete" }; xkb_compatibility { include "complete" }; xkb_symbols { include "pc/pc(pc105)+pc/de" }; xkb_geometry { include "pc(pc105)" }; QImage::convertDepth: Image is a null image QImage::smoothScale: Image is a null image Link points to "/var/tmp/kdecache-root" FreeFontPath: FPE "/usr/lib/X11/fonts/misc" refcount is 2, should be 1; fixing. Its not only a KDM Problem. GDM failed too. I get simple the message "authentification failed" but this message is displayed after I entered the username but before i can enter the password. The gdm logfiel looks like the kdm file without the QImage lines. A normal login without a Display Manager is no Problem and there is no error Message. Has somebody a good advice for me? Hannes
