Professor Ripley,
One thing that you may want to check is to see what the dpi setting is
for your display in the X11 setup.
On my Dell i8200 laptop, which has a 1600 x 1200 LCD panel, I have the
dpi set to 133 (305 mm x 229 mm), which is the actual measure. If I set
this to some other figure then all graphics and fonts are scaled
accordingly.
On RH 9, this is set under System Settings -> Display -> Advanced.
This is also reflected in /etc/X11/XF86Config:
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell 1600x1200 Laptop Display Panel"
DisplaySize 305 229
HorizSync 31.5 - 90.0
VertRefresh 59.0 - 85.0
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce 4 (generic)"
VideoRam 65536
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1600x1200" "1400x1050" "1280x1024" "1280x960" "1152x864"
"1024x768" "800x600" "640x480"
EndSubSection
EndSection
I hope that is of some help to you. If I can provide any other
information, please let me know.
Best regards,
