After hibernation I get the following error when I tried to connect to monitor
$ xrandr --output LVDS1 --off --output HDMI1 --auto
xrandr: Configure crtc 1 failed
This does not happen in kernel in kernel v4.6.7 but do happen in kernels v4.7.4
I don't see anything related to this in the kernel log.
This happens after hibernation but not after suspend to ram.
I use a Thinkpad T430
$ lspci | grep -i vga
