we have been using svga lib for about 18 months for several embedded
projects on a variety of hardware.
we recently have discovered a problem when moving to a new hardware
platform - The ETX P3 module from jumptec.
This board uses a ATI Rage Mobility chip set and we are using the VESA
drivers settings in svgalib as standard. Which is what we have always
done. we are using 1024 by 768 resolution.
After a random time which can be between 2 and 10 minutes the VGA
monitor screen will flicker once - just like it is losing sync. This
will then continue to flicker at these random intervals.
The Same hradware does not exhibit this problem under windows.
Has anyone experience of this problem with the Rage chip or is there a
better driver that we should be using or a driver setting we can tweak.
regards
Nick
