Would an > acceleracted X server solve the problem? TIA. You mean xdm is managing two separate X servers? There are two virtual consoles with xdm login screens on them? That sure isn't the default config, but it sounds like what is happening to you. See the file /etc/X11/xdm/Xservers to control the number and type of X sessions xdm is to manage. Most people only want one local session managed by xdm. If you're running slink (the currently frozen distribution), I suggest trying my latest test build of the X packages, at http://master.debian.org/~branden/xfree86/ . One thing you might try if you're feeling adventurous is to yank the Voodoo card and see what (if anything) changes without it. If your Monster 3D card is confusing your primary display adapter, that's very bad. Either it's being poorly behaved, or something is waking it up -- and there aren't too many Linux applications that speak to Voodoo cards. As far as video cards not handling mode switches, in some cases this is the X server's fault. For instance, on my card (ATI Xpert@Play PCI), the xserver-mach64 works just fine. But if I use xserver-svga (which supports the card), anytime I switch away from the X display (by killing the server or just CTRL-ALT-Fn'ing away), I lose my entire console. The machine has to be rebooted. Maybe this is fixed in 3.3.3 -- I'll find out when I can close the book on 3.3.2.3 for slink. -- G.
