Hi, Whoops, looks like I only sent my note about comparisions between vesafb and rivafb 0.72 to Jeff Garzik. Anyways, to quickly sum up what I am seeing, here's the output from fbset -i under rivafb 0.72 and vesafb, both running at 1024x768-16:
rivafb 0.72: mode "1280x1024-76" # D: 135.007 MHz, H: 81.134 kHz, V: 76.254 Hz geometry 1280 1024 1280 2048 16 timings 7407 248 32 34 3 104 3 rgba 5/10,5/5,5/0,0/0 <=== endmode Frame buffer device information: Name : Riva RIVA-UTNT2 Address : 0xd6000000 Size : 33423360 Type : PACKED PIXELS Visual : DIRECTCOLOR XPanStep : 1 YPanStep : 1 YWrapStep : 0 LineLength : 2560 Accelerator : No
vesafb: mode "1280x1024-77" # D: 131.096 MHz, H: 80.328 kHz, V: 76.649 Hz geometry 1280 1024 1280 1024 16 timings 7628 160 32 16 4 160 4 rgba 5/11,6/5,5/0,0/0 <=== endmode Frame buffer device information: Name : VESA VGA Address : 0xd6000000 Size : 4194304 Type : PACKED PIXELS Visual : TRUECOLOR XPanStep : 0 YPanStep : 0 YWrapStep : 0 LineLength : 2560 Accelerator : No
Notice how the rgba lines are different between the two. Vesafb appears with correct colors, and rivafb does not. I guess I'll have to study the 2 drivers and see if I see some obvious error somewhere.
