Subject: [PATCH] x11: Bypass SetGammaRamp when changing gamma
|
|
|
0a8bd8 |
|
|
|
0a8bd8 |
Recent Xorg has broken dynamic colors setting, so calling SDL_SetGamme()
|
|
|
0a8bd8 |
does not have any effect here. Recent means xorg-server >= 1.7, since 2010.
|
|
|
0a8bd8 |
See <https://bugs.freedesktop.org/show_bug.cgi?id=27222>.
