I have errors related to rgb databse with xorg-x11-6.8.901. (a lot of Cannot parse color "black", XWin::allocColor() : failed to alloc : wheat, urxvt: can't get colour 'white') It looks like some programs are searching for the rgb database in /usr/lib/rgb but it is actually located in /usr/lib/X11/rgb.txt. (i get the following errors in xdm : Couldn't open RGB_DB '/usr/lib/rgb'). They seems to be differents definitions of LIBDIR beetween the various definition of DefaultRgbDatabase. Benoit Reproducible: Always Steps to Reproduce: 1. 2. 3.
Problem is your xorg.conf has RgbPath incorrect. Check it and update it to /usr/lib/X11/rgb from /usr/lib/rgb.
It worked. Thank you !
