Hi,

After hibernation I get the following error when I tried to connect to monitor
through hdmi:

$ 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
and v4.8.0

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
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)

regards,

Gaston
