[Techtalk] X and resolution changes

[Tabatha Persad]

Hi Hamster,

I had that problem with Mandrake a few years ago during an 8.0 install.  
Haven't had it do that in 8.1.  The way I fixed it was to open a shell and as 
root, run xf86config, but I'm a little short on the details.  Somewhere in 
the configuration file there is a line that determines whether you are using 
a virtual screen.

You might find this article helpful...

Now keep in mind, if you run xf86config from a shell to edit your settings, 
you're playing with fire!  But viewing the file might give you clues what 
line to look for in the xf86config file ( /etc/X11/XF86Config).  

There is another article at Linuxnewbie.org about Installation and 
configuration of XFree86 at: 
http://www.linuxnewbie.org/nhf/intel/x-windows/xfree_4-gettingstarted.html.  
Maybe this can give you further clues.

I am unsure which distro you use.  If Mandrake, you should be using your 
Mandrake Control Center to accomplish this, in other distros it might be 
different.  

I'm sorry I don't have a quickie answer for you.  I know that running  
xf86config will edit this file in a shell, but it could also cause you 
keyboard/mouse/video problems if you don't do something right so you want to 
be careful!

At the very least, you can compare your XF86Config file to one that doesn't 
have the virtual screen and see what lines point to it.

Hope to have helped even a little!
