Hi, I use fedora-legacy's yum updated a redhat 9.0. http://www.fedoralegacy.org I updated most rpms excetp kenerl* mysql*. However, after this update, I can't get the X display started. During the X window starting up, the screen is flashing between mode '1024x786' and '720 x 400'. After a while, showing an error message 'failed to start the display server severial times in a shor time peroid'. If i login as root in the text mode and issue a command 'startx', the xwindow started and login into kde. as a normal user, issue a command 'startx', get a window terminal, looks like 'Fvwm' below is a part of the /var/log/XFree86.0.log Yuandan Jan 17 14:13:26 frog nfs: Starting NFS services: succeeded Jan 17 14:13:26 frog nfs: rpc.rquotad startup succeeded Jan 17 14:13:26 frog nfs: rpc.nfsd startup succeeded Jan 17 14:13:26 frog nfs: rpc.mountd startup succeeded Jan 17 14:13:26 frog Win4Lin: Starting Win4Lin: Jan 17 14:13:29 frog Win4Lin: Failed to insert the mki-adapter module.
