Package: redshift
Version: 1.7-2
Severity: minor
Tags: patch upstream
The intel X.org driver supports virtual outputs [1] and I use these to extend
my desktop to three monitors using the NVidia card in my ThinkPad T420. These
virtual outputs, however, do not support the RAndR Gamma properties, and
redshift crashes. With the attached patch, redshift ignores those virtual
outputs and only adjust gamma on the real outputs, which is fine (I run a
second redshift for the NVidia X server to adjust the third display as well).
Please consider doing something similar, thanks.
