...mapping of colors in 30bpp framebuffers. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- If I bump the gamma size to 1024, then all existing software will start failing since the gamma set ioctl expects the size to match. But xf86-video-nouveau does not pull in the "real" gaamma size and just assumes the default 256. This lets 30bpp get going a bit though while the proper solution is figured out. drm/nouveau/nv50_display.c | 15 ++++----------- 1 file changed, 4 insertions(+), 11 deletions(-) diff --git a/drm/nouveau/nv50_display.c b/drm/nouveau/nv50_display.c index 0e...

This is what was done prior to the big refactor in kernel 3.8, and what was done by xf86-video-nv. Experimentally, it seems like there's some sort of issue with the high-res lut to be used there. Tested on G92. This ends up mattering because fbcon/fbdev chooses the C8 fb format for low-vram systems, which can occur with some IGP-based configurations with little "stolen" vram.
