Hi list :-)

I had trouble getting a standard 800x600@60Hz VGA signal to display correctly on my monitors. Measuring the output showed that the front and back porches were swapped both for hsync and vsync. After reading the source I think I found the error in drivers/video/omap2/omapfb/omapfb-main.c. Patch attached.

http://www.xfree86.org/3.3.6/fbdev6.html shows the way it should be, but todays code sets:

hfp = left margin
hbp = right margin
vfp = upper margin
vbp = lower margin

I tested a patched kernel with 800x600@60Hz on two different monitors and a vga grabber, and it solved my issues.
