[Bug 1410406] Re: black screen after booting, 100% cpu usage

 

Thank you, Andrew, for a prompt answer. I used the workaround with
"active-monitor" already before 2.0.1. I only hoped the new bug fix
would solve this problem. It obviously helped to many others but in some
specific configurations like mine it still fails. I will patiently wait
for a "smarter" algorithm and in the meantime I will use the suggested
workaround and will take a look at including xrandr script in my
lightdm.conf.
