Comment(by usbhostman):
The fb.modes file says this:-
# Timings for GTA01 VGA and QVGA mode
mode "480x640"
# D: 26.000 MHz, H: 43.334 kHz, V: 65.657 Hz
geometry 480 640 480 640 16
timings 38461 104 8 2 16 8 2
accel false
endmode
mode "vga"
# D: 26.000 MHz, H: 43.334 kHz, V: 65.657 Hz
geometry 480 640 480 640 16
timings 38461 104 8 2 16 8 2
accel false
endmode
mode "240x320"
# D: 8.475 MHz, H: 24.635 kHz, V: 75.569 Hz
geometry 240 320 240 320 16
timings 118000 88 8 2 2 8 2
accel false
endmode
mode "qvga"
# D: 8.475 MHz, H: 24.635 kHz, V: 75.569 Hz
geometry 240 320 240 320 16
timings 118000 88 8 2 2 8 2
accel false
endmode
but if I change to qvga mode fbset says:-
mode "240x320-204"
# D: 25.000 MHz, H: 69.444 kHz, V: 204.248 Hz
geometry 240 320 240 320 16
timings 40000 104 8 2 16 8 2
rgba 5/11,6/5,5/0,0/0
endmode
while in vga mode it says:-
mode "480x640-63"
# D: 25.000 MHz, H: 41.667 kHz, V: 63.131 Hz
geometry 480 640 480 640 16
timings 40000 104 8 2 16 8 2
rgba 5/11,6/5,5/0,0/0
endmode
So it seems as if fbset is ill. I am using FSO milestone 2.
