I find that solution ok the first 4 times, then it just becomes annoying ;-)

emacs /etc/X11/XF86Config-4 is a much better solution :-)

Anyway, a couple of tips:

You can't have screens taking up more memory than your graphics card 
has. Therefore, do a quick calculation just in case.

Most drivers should detect memory itself, but if it doesn't detect as 
much as you know is there, you can adjust it in the Device section. 
Here's mine, from the office P4:


Section "Device"
       Identifier      "Generic Video Card"
       Driver          "mga"
EndSection

At home, on the Voodoo3-equipped AmigaOneG3-SE, I'm using tdfx and have 
an option mem 16384k or something. Memory is failing, and no user 
servicable parts inside.

If you have set the monitor section to use too low frequencies, some 
resolutions are just not possible.

Here's mine:

Section "Monitor"
       Identifier      "Generic Monitor"
       HorizSync       30-107
       VertRefresh     50-85
       Option          "DPMS"
EndSection

On the A1G3-SE, I have like 30-95 and 50-160, but the difference is 
marginal. The difference between my monitors is two generations (both 
are Eizo 21" screens), so one of them doesn't handle the higher hsync 
frequencies.

Then on to section Screen. Here's mine:

Section "Screen"
       Identifier      "Default Screen"
       Device          "Generic Video Card"
       Monitor         "Generic Monitor"
       DefaultDepth    24
       SubSection "Display"
               Depth           1
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
       SubSection "Display"
               Depth           4
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
       SubSection "Display"
               Depth           8
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
       SubSection "Display"
               Depth           15
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
       SubSection "Display"
               Depth           16
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
       SubSection "Display"
               Depth           24
               Modes           "1600x1200" "1280x1024" "800x600"
       EndSubSection
EndSection

This is the same on both machines, actually. Depth is how many bits of 
colour to use per pixel. Modes is just a list of possible resolutions on 
that depth, taking max memory and pixel clock/memory clock into 
consideration. Play around, and if you break something just roll out the 
backup <-- My version of "take two of these and call me in the morning" ;-)
