Fixed bug #80 Date: 21 Apr 2003 17:20:20 +0100 From: Alan Swanson <swanson@uklinux.net> Subject: [SDL] New XFree 4.3 Video Mode Patch If you look at the unsorted list of modes returned by X, here's mine; 1280 x 1024 @ 85.0 > 1024 x 768 @ 100.3 > USER 800 x 600 @ 125.5 > SET 640 x 480 @ 124.9 > 1280 x 1024 @ 75.0 ] 1280 x 1024 @ 60.0 ] 1280 x 960 @ 85.0 ] X11 1280 x 960 @ 60.0 ] AUTO 1152 x 864 @ 75.0 ]=20 1152 x 768 @ 54.8 ] 960 x 720 @ 120.0 ] ... 640 x 400 @ 85.1 ] 256k 576 x 432 @ 150.0 ] 249k PIXEL 640 x 350 @ 85.1 ] 224k COUNT 576 x 384 @ 109.6 ] 221k ... The user set modes come first followed by X set modes which are ordered by decreasing number of pixels and refresh. The reason why every other library or program not using SDL working is due to SDL scanning the modes in reverse getting X11 provided modes modes with the lowest refresh.
