Description Michael Geddes 2006-01-16 15:07:13 UTC 
Radeon has a built-in Xinerama mode that nearly everything else seems to be able to detect and play nicely with except for SDL.

It's the standard Xinerama problem where going fullscreen splits you across the two screens - even if the size of the application is only the size of 1 screen.

Patch for Xinerama support in SDL

Subject: [SDL] Patch for Xinerama/Fullscreen support

Hi

I made a small patch to handle fullscreen support in Xinerama in a
better way, so that the application now starts on the first Xinerama
"screen" and not any longer above all Xinerama "screens". I found
Xinerama suppport already in SDL (1.2.5), but it was disabled as it
simply doesn't work correctly.

Any discussion about my patch would be appreciated. Maybe it will be
applied (in an improved form) for future releases of SDL.

Setting Sam as "QA Contact" on all bugs (even resolved ones) so he'll definitely be in the loop to any further discussion here about SDL.

This is fixed in Subversion with a complete rework of the Xinerama support.
