... I seem to have got the idea from somewhere that the 
virtual keyword is not supported in xorg.conf anymore. I 
think it was from a post on another mailing list where I 
found this link:

https://bugs.freedesktop.org/show_bug.cgi?id=11418

BTW - is this the same X11 server code that Fedora uses? 
There seems to be more than 1 version of the X11 server code 
available for downloading.

I did a full update of F9 and the virtual keyword is still 
working OK. So I apologise for my original post comments.

My problem is with the xorg.conf file not having a monitor 
section in it.

The font sizes in F6 and F8 work fine without the monitor 
section and a DisplaySize keyword in xorg.conf.

----------------------------------------------------
This is my full xorg.conf I'm using now with F8:

# Xorg configuration created by pyxf86config

Section "ServerLayout"
         Identifier     "Default Layout"
         Screen      0  "Screen0" 0 0
         InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
         Identifier  "Keyboard0"
         Driver      "kbd"
         Option      "XkbModel" "pc105"
         Option      "XkbLayout" "gb"
EndSection

Section "Device"
         Identifier  "Videocard0"
         Driver      "nv"
EndSection

Section "Screen"
         Identifier "Screen0"
         Device     "Videocard0"
         DefaultDepth     24
   SubSection "Display"
     Viewport   0 0
     Depth     24
     Virtual 800 1800
   EndSubSection
EndSection

----------------------------------------------------

This is my xorg.conf for F9

# Xorg configuration created by system-config-display

Section "ServerLayout"
         Identifier     "single head configuration"
         Screen      0  "Screen0" 0 0
         InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"

# keyboard added by rhpxl
         Identifier  "Keyboard0"
         Driver      "kbd"
         Option      "XkbModel" "pc105"
         Option      "XkbLayout" "gb"
EndSection

Section "Device"
         Identifier  "Videocard0"
         Driver      "nv"
EndSection

Section "Screen"
         Identifier "Screen0"
         Device     "Videocard0"
         DefaultDepth     24
         SubSection "Display"
                 Viewport   0 0
                 Depth     24
                 Modes    "800x600" "640x480"
         EndSubSection
EndSection

----------------------------------------------------

I have tried changing the above F9 Section "Screen" to:

Section "Screen"
         Identifier "Screen0"
         Device     "Videocard0"
         DefaultDepth     24
         SubSection "Display"
                 Viewport   0 0
                 Depth     24
                 Virtual 800 1800
                 Modes    "800x1800" "800x600" "640x480"
         EndSubSection
EndSection

But the font sizes are *way* to large. This is why I'm still 
using F8.

The Xorg.0.log file (using startx -- -logverbose) tells me:

'''
(WW) No monitor specified for screen "Screen0".
         Using a default monitor configuration.
'''

I think I need a Monitor section in the F9 xorg.conf to set 
the font size with the DisplaySize keyword. I'm not sure how 
to go about adding the Monitor section to the F9 xorg.conf 
to implement this. Any suggestions would be greatly appreciated.

I enclose an attachment showing the present font sizes in mc 
with a virtual setting of 800 x 1800.

Kind Regards,
