First of all happy new year to everyone, OK, my problem is as follows: I re-installed Mandrake Linux 6.1 on my pc, but now i cant put xscreensaver to work, i read the man pages of xscreensaver and added the following lines to the Xsession file: xscreensaver-commmand -exit xscreensaver & so everyone could activate their xscreensaver when they log on, i made this work once but now it doesnt, the users have their ~/.xscreensaver files. If someone but root runs the xscreensaver-demo they can test the screensaver, but if i try if with root i get the "xscreensaver seems not to be running on display :0.0" warning message. Also at the first console i get the following messages depending if root logged on or it was another user: if it is another user: /etc/X11/xdm/Xsession: line 4: 787 Aborted xscreensaver-command -exit xscreensaver disabling builtin xscreensaver xscreensaver: uyou can re-eneable it with "xset s on" if it is root: /etc/X11/xdm/Xsession: line 4: 748 Aborted (core cumped) xscreensaver-command -exit AUDIT: Jan 5 07:33:05 2000: 411 X: client rejected from local host Xlib: coneection to ":0.0" refused by server Xlib: client is not authorized to connect to server xscreensaver: cant open display ":0" xscreensaver: initial effective uid/gid was root/root (0/0) xscreensaver: running as nobody/nobody (99/99) xscreensaver: problems at start up are usually related to authorization problems, did u read the manual? bla bla bla (i did read it, but most likely i missed something important) i hope someone can answer me this, Juan Jose Natera P.S. i have changed nothing else besides the files mentioned above, i just installed my Mandrake 6.1 and then tried to setup the xscreensaver.
