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.
