> Let us know what blows up. ;-) > > Dale Nothing blew up ;-) I was successful removing X, downgrading, and getting X working again with xorg-server-1.5.3 and libxcb-1.1
FYI, the working package.mask file for this operation is: >=x11-libs/libXext-1.0.5 >=x11-libs/libX11-1.2 >=x11-libs/libxcb-1.4 >=x11-base/xorg-server-1.6 >=x11-base/xorg-x11-7.4 >=x11-proto/xproto-7.0.15 >=x11-proto/xextproto-7.0.5 >=x11-libs/xcb-util-0.3.5 >=x11-proto/xcb-proto-1.2 However, this must not have restored my previous X configuration fully because Mathematica still crashes. So I've decided to abandon this attempt, remove all masks, and allow the full X upgrade because I reinstall all the X packages back onto my system. While some folks here probably think this attempt foolish, I still think it was worth a try, and I learned some new things, which is always good. I appreciate everyone's help and support with this.
