Bug Description
I have a HP LP2475w monitor. Sometimes when the system has put it to sleep, it fails in bringing it back up again. The screen remains blank. Even changing virtual terminals with ctrl+alt+f1 does not work. Ssh'ing in and running 'sudo service lightdm restart' makes it come back up again.
This error shows up in dmesg:
[18380.721810] [drm:drm_
This monitor worked flawlessly on my previous computer which had NVidia + the binary driver.

Usually this is a sign of FDI or DP link training error. Can you please add drm.debug=6 to your kernel command line and attach the output of dmesg after your monitor fails to wake up?
