Hello, Gentoo. HEADS UP!!!
If you start your X server from the command line with, e.g. startx, you now need to set the new(?) suid USE flag for the xorg-server package. This flag causes the binary to be installed with the setuid file flag, which causes it to run as root. The developers, in this instance, failed to raise the ebuild's version number from 1.20.3 when making this change, and also didn't notify users by a NEWS item, that I can see. The matter was fairly intensively discussed in bug #669648 in Gentoo's bugzilla. So - if you get a permissions error whilst trying to start X, setting the suid USE flag may well be the solution. -- Alan Mackenzie (Nuremberg, Germany).
