Hi again
Seems not to change anything:
/usr/sbin/fbset -i:
mode "1024x768-76"
# D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz
geometry 1024 768 1024 768 32
timings 12714 128 32 16 4 128 4
rgba 8/16,8/8,8/0,8/24
endmode
Frame buffer device information:
Name : VESA VGA
Address : 0xe0000000
Size : 6291456
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 0
YPanStep : 0
YWrapStep : 0
LineLength : 4096
Accelerator : No
I suppose that it's because the second 768 (virtual y resolution)
in the line: geometry 1024 768 1024 768 32
But how can I increase this number. When using the VESA driver I
probably should do this during boot ... But how ???
Thanks for your help :)
