Hello, The situation is as follows : Seeing it as more a global debian tread than a TDE one, i went to the debian-facile.org forums where a couple of suggestions were made to me. The first one regarded the /var/log/Xorg.o.log file where it was pointed that the acceleration and enhancement of my graphic card were not enabled. I installed the amd firmware. Then, as root, the desktop worked with no slowlyness problem, videos worked normally and synchronized with the sound (yet before, they worked better than as user). When logging out, there is no problem, it falls back to the tdm desktop manager. I can also stop or reboot the PC from tboth he desktop and TDM. Not so as user. User remains slower, slow starting kmail (not used under root), slow starting firefox, extremely slow starting and playing any video and with the sound totally unsynchonized. I eliminated the autogenerated hidden files and directories that don't change the desktop configuration, like DCOP, aso, .... to have them regenrated from scratch : no change. If i try to logout as user, i get the mouse pointer on a black screen and it remains undefinidetly. To go back to the TDM desktop manager, i have first to go to another console (Alt+Ctrl+Fx), log in as root and command killall Xorg Then i fall back to the TDM manager. But if i try to stop the computer from there i have to end up with a hard shutdown. What i can do is, from TDM, go back to the root desktop but i cannot reboot or shutdown the PC but a hard way. So, i come back to You since it might be a Xorg/TDE problem that affect the users. My /home and /root are individual partitions.
