Uninstall old X.org

Code: Cleaning out xorg 6.*

emerge -Ca xorg-x11
rm -rf /usr/lib/opengl/xorg-x11
rm -rf /usr/lib/libGL*

Emerge X.org 7

First, you should set the appropriate VIDEO_CARDS and INPUT_DEVICES flags in /etc/make.conf. To see what flags are available, run emerge -Dpv xorg-x11. On a typical machine with nvidia video, it might look like this:

INPUT_DEVICES="keyboard mouse"
# VIDEO_CARDS="nv nvidia vesa" --for nvidia
VIDEO_CARDS="radeon fglrx vesa"

Code: Emerging xorg-x11 
emerge -Dv xorg-x11


A few useful x11 tools that used to be included in the 6.8 build are now their own packages, you can emerge some or all of them now if you know you'll want them: 
Code: Emerging optional tools 
emerge -Dav xev xdpyinfo xvinfo xset xdriinfo xprop
If you would like some extra fonts, you can emerge them now also: 
Code: Emerging fonts 
emerge -Dav font-adobe-100dpi font-adobe-75dpi font-adobe-utopia-100dpi \
font-adobe-utopia-75dpi font-bh-100dpi font-bh-75dpi font-bh-type1 \
font-bh-lucidatypewriter-100dpi font-bh-lucidatypewriter-75dpi \
font-bitstream-100dpi font-bitstream-75dpi ttf-bitstream-vera \
