Description Tom Horsley 2015-11-04 01:46:39 UTC 
Running this command previously made my screen have gloriously crisp and full range color:

xrandr --output HDMI2 --set "Broadcast RGB" Full

Now, all it does is change the value "xrandr --properties" reports, while having no effect at all on the screen. I get the stupid gauze overlay effect all the time.

This happened fairly recently when I got updates for my Fedora 22 system. Some possibly relevant packages are:

mesa-dri-drivers-10.6.9-1.20151008.fc22.x86_64
xorg-x11-drv-intel-2.99.917-15.20150729.fc22.x86_64
xorg-x11-server-utils-7.7-15.fc22.x86_64

P.S. There was once some hint that some sort of firmware blob might be able to be specified on the command line to override this setting at boot. Any progress on that?

This looks like a probable duplicate of bug 92206.
