Hi guys,

I'm trying to enable double buffering by setting virtual screensize, 
y-offset and panning with ioctl. But FBIOPUT_VSCREENINFO seems to be an 
invalid argument (The quick test is "fbset -vyres 960", which also uses 
ioctl, to see the error) - As far as i can tell from others who have had 
the same issue on other platforms, this is due to limitations in the video 
driver. Which brings me to my question:

Has anyone else experienced this, and is this "corrected" in a later 
version of the video driver? Also, i'm noticing that that ioctl returns -1 
when called with FBIO_WAITFORVSYNC - Could this also be due to driver 
issues?

Thank you in advance,

Best regards,
Martin
