Seems like beginning from xorg-server 1.2.0 the script etc/X11/xinit/xinitrc.d/92xprint-xpserverlist.sh was changed. So sed command (see Bug #134941) in all new ebuilds fails to make replacement properly in it. Here are patches for 1.3.0.0 and 1.4. Reproducible: Always

Created attachment 131843 [details, diff] 1.4 patch
I've just noticed that additional fix is needed. etc/X11/xinit/xinitrc.d/92xprint-xpserverlist.sh should be executable to work. Droppin' new patches.
Created attachment 131924 [details, diff] new patch for 1.3.0.0 ebuild
Created attachment 131926 [details, diff] new patch for 1.4 ebuild
Created attachment 131927 [details, diff] new patch (again :) for 1.3.0.0 ebuild
Should be fixed in xorg-server-1.4-r2.
