te: 27 Jun 2003 21:16:01 +0100 From: Alan Swanson Subject: [SDL] New XFree 4.3 Video Mode Patch The current patch to fix the issues with XFree 4.3 it is a bit of overkill to a simple problem. Default screen settings should be set in X, not selected by SDL with environment variables. Any program or user using non-standard or unset display modes get what they deserve :-) 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 ] 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 was working is due to SDL scanning the modes in reverse getting X11 provided modes modes with the lowest refresh. The solution is to scan forward for the first user set mode or highest X mode. The qsort still keeps user set modes above higher refresh modes added by X. For the best match we still reverse search for the nearest larger size and then try to find a higher version of it.
