When running:
patch -p1 < xserver-xorg-video-intel-2.18.0_virtual_crtc.patch
I get the following error:
can't find file to patch at input line 13

The text leading up to this was:
|This is a patch that adds a single virtual CRTC to an intel driver. The
|motivation is that this output may be turned on and cloned (in userspace) to
|another X server, which may be running on a different graphics card. My usecase
|is a triple-head (with hotplug) setup on a NVIDIA Optimus laptop. See
|https://github.com/liskin/hybrid-screenclone.

After line 5, you can execute
dch -l+versionto uniquely identify the patched version to the apt system, as outlined in a comment by Stephan Fabel. Replace+versionwith anything you like.The command will ask you to provide a "changelog message", this is a good place to store the reference to the original instructions.
