Description Sami Näätänen 2009-02-17 01:00:51 UTC 
Created attachment 298 [details]
patch against revision 4428 to obey the configured X11 XRANDR video driver support.

Found out that 
src/video/x11/SDL_x11modes.c undefs the
SDL_VIDEO_DRIVER_X11_XRANDR value and thus disables the XRANDR video modes.

This prevents any SDL program from changing resolution.

FIX: Remove the undef -> make, make install.
TEST: Make the tests and run them with fullscreen and with different geometry settings and everything works.

The VIDMODE and XINERAMA extensions are similarly also disabled, but I didn't test those.

Test case with X11MODES_DEBUG enabled:

Comment 1 Sam Lantinga 2009-10-10 12:24:29 UTC 
I'll re-enable XRANDR modes when I re-implement fullscreen support.

Thanks!

lshw output for Ubuntu 11.10 x86, GeForce 8800 GT
Comment 5 Martin Kallman 2012-04-24 07:31:34 UTC 
Issue appears to have resurfaced as of 6305.

On Ubuntu 11.10 x86, with NVIDIA's proprietary driver (version 173) and GeForce 8800 GT, SDL only reports one mode (the current desktop mode) as available when using SDL_GetNumDisplayModes / SDL_GetDisplayMode.

This seems to be driver-specific as the same setup works correctly under VMWare with the VMWare SVGA II adapter.

lshw output attached.
Comment 6 Martin Kallman 2012-04-24 07:35:33 UTC 
Also note that the 'nvidia' driver is not found by SDL.

Comment 7 Sam Lantinga 2012-10-03 11:29:09 UTC 
Please enter a separate bug for the NVidia issue.  There really isn't anything SDL can do if the X server doesn't pick up the nvidia driver and advertise XRandR support.
