Comment 267 for bug 1220426

Try building with dpkg-buildpackage -b.

That command appears to complete with no errors. Afterwards I have the following .deb files in the parent directory:

xorg-server-source-lts-utopic_1.16.0-1ubuntu1.2~trusty2_all.deb
xserver-xephyr-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb
xserver-xorg-core-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb
xserver-xorg-core-lts-utopic-dbg_1.16.0-1ubuntu1.2~trusty2_amd64.deb
xserver-xorg-dev-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb
xwayland-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb

The instructions from Patrick Mertens in posting #212 said

There should now be 11 "*.deb" files in that folder (run ll *.deb to check).
As nielsmayer pointed out we need to install only two: xserver-common_1.15.1 and xserver-xorg-core_1.15.1 (The exakt file names vary depending on your distro! Just type the first few letters and hit the TAB key to get them typing this command):
~/Downloads$ sudo dpkg -i ./xserver-common_1.15.1-0ubuntu2.3_all.deb ./xserver-xorg-core_1.15.1-0ubuntu2.3_amd64.deb

There is an xorg-core deb, but no xserver-common deb. Should I install the xephyr deb instead? The xwayland one?
