Description Guillaume Castagnino 2011-05-26 13:02:37 UTC

When I load my ICC profile, there is no error. moreover, when reading the LUT, the ICC profile is in memory from informations I get from argyllcms tool.
BUT : there is no visual change : the ICC profile has no more effect. Visually, it's a no-op operation with 2.6.39.
Downgrading to 2.6.38.7 fixes the issue.


Configuration :
- xorg 1.10.1.902
- x11-drivers/xf86-video-nouveau GIT from 20110323 (last git change)
- kernel 2.6.39 (nouveau DRM, KMS enabled)
- nvidia quadro NVS 290 (NV86)


- Loading the ICC profile inside the LUT :
$ argyll-dispwin -v -I /usr/share/color/icc/SyncMaster214T.icc
About to open dispwin object on the display
About to install '/usr/share/color/icc/SyncMaster214T.icc' as display's default profile
Installed '/usr/share/color/icc/SyncMaster214T.icc' and made it the default
About to destroy dispwin object

- Then checking the LUT state :
$ argyll-dispwin -v -V /usr/share/color/icc/SyncMaster214T.icc
About to open dispwin object on the display
Verify: '/usr/share/color/icc/SyncMaster214T.icc' IS loaded (discrepancy 0.0%)
About to destroy dispwin object


When I load the profile, Xorg.0.log output this logs lines :

same here. The nouveau driver ignores ICC profiles from both dispwin (Argyllcms) and gnome-color-manager.

Comment 2 Emil Velikov 2011-06-18 05:28:18 UTC

The issue has been bisected and fixed in nouveau-git [1] by commit f66b3d55 (drm/nv50/disp: fix gamma with page flipping overlay turned on)
