And finally, I want to blank the screen (using the accel engine) before setting the new mode, so that we come out "clean" of the mode setting (without ugly artifact), and I will probably clean both fb's (simpler).That would break X with UseFBDev.How so ?X assumes that the framebuffer (as in video RAM) contents are preserved on mode switches.
Which I consider bogus :) Oh well... does it do a lot of other crappy assumptions like that ? What if I just can't allocate it and decide to put it elsewhere in vram ? (unlikely with my current scheme but possible). X needs to be fixed. Ben.
