Date: Mon, 24 Feb 2003 16:31:25 -0500 From: Ragnvald "Despair" Maartmann-Moe IV Subject: SDL x11 video mode selection bug Hi, I've found an oddity with video mode selection. I recently added a bunch of oddball video modes to my XF86Config, to support weird resolutions xine & mplayer need if I don't want to beat my cpu up with video scaling. Since adding them, SDL started picking the biggest video mode it could find that matched the height constraint. Getting a narrow vertical strip of QuakeForge (I code for the project, so needless to say it's my favorite test) in the middle of an 800x480 screen, instead of the 640x480 I asked for annoys me tremendously. So here's a patch that tries a bit harder to get an exact match. I didn't touch the XiG section, since I can't test that, but I'd bet a similar patch would prevent similar problems there. --Ragnvald "Despair" Maartmann-Moe IV
