I am pretty sure your bug is the same as theirs. I will dupe these
together. If you have time

Thanks for looking into this (minor) problem.
No, it does not restore the blanked screen. In fact I'm not sure how far

b. Test against the Intel experimental drm kernel tree, which we now do
daily builds of:
Thanks feffemannen,
Would you mind checking if the following command restores the blanked
monitor after reproducing the problem?
xset dpms force on
I'm wondering if this is just a dpms setting issue. I have an idea on
how we could workaround it if it is.
