The bug is relevant for 4.15? too. A bisect pointed me to: b8e2b0199cc377617dc238f5106352c06dcd3fa2 is the first bad commit¬ commit b8e2b0199cc377617dc238f5106352c06dcd3fa2¬ Author: Peter Rosin <peda@axentia.se>¬ Date: Tue Jul 4 12:36:57 2017 +0200¬ ¬ drm/fb-helper: factor out pseudo-palette The pseudo-palette has nothing to do with the crtc, so move it¬ out of the crtc loop and update the palette once, then break out¬ early.¬ ____¬ Signed-off-by: Peter Rosin <peda@axenita.se>¬ Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>¬ Link: http://patchwork.freedesktop.org/patch/msgid/1499164632-5582-2-git-send-email-peda@axentia.se HTH Elimar Created attachment 274827 [details]

I can confirm. All my colors with astdrmfb are wrong on VT..
probably a dupe of bug 198293, although this one has more info in it |
Colours on vt's are broken. I.e. white is shown as red. If I $(fbgrab -c1 blo.png) the picture shows correct colors, though. I tested 4.9.65 and 4.13.13 which are looking normal. $ lsmod | grep ast ast 61440 1 drm_kms_helper 147456 1 ast ttm 98304 1 ast drm 339968 4 ast,ttm,drm_kms_helper i2c_algo_bit 16384 2 igb,ast $ cat /proc/fb 0 astdrmfb $ uname -r 4.14.9-toy-lxtec-amd64 # fbset mode "1600x1200" geometry 1600 1200 1600 1200 32 timings 0 0 0 0 0 0 0 accel true rgba 8/16,8/8,8/0,0/0 endmode Thanks in advance Elimar
