I have ServerArgsLocal= and -nolisten TCP removed from xserverrc. Unfortunatly I have forgotten to run your cli commands, removed KDE and installed Gnome, still not functioning ( I am going to reinstall it) But I couldn't wait I have tested the local function from 2 other pc's Etch + Gnome = OK Slackware + KDE = Ok there was no need to modify kdmrc ! The pleasant surprise: in my local-X I have not only the webrowser where I can choose a streaming, and the VLC console pops up on my local host as a child of the browser window ! So what is working: Remote: old portable Pentium II 66Mhz 96 Mb Ram Debian Lenny + JWM + sound card. Local in xterm: xhost + telnet to Remote export Dispalay Konqueror + VLC Many Thanks, I am going to try the Lenny / KDE later Dieder -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
