Screen stays blank after autolock despite key presses

About one in seven times when switching the display on after a period of time it’s been off (normally induced by xfce power manager, but also after suspends and locks as well), the screen will stay black. The keyboard lights stay on and the fans continue to spin, but the screen will refuse to come on despite many button and touchpad combinations. The only workaround I’ve found is to reboot. Any ideas?

Things I’ve tried -

  1. swapping bumblebee to the noveau drivers - this got rid of a few errors in dmesg, but problem still persists. Could this issue be related to the error below?
kernel: pcieport 0000:00:1c.0: Data Link Layer Link Active not set in 1000 msec
kernel: pci 0000:01:00.0: can't change power state from D3cold to D0 (config space inaccessible)
  1. Going straight to suspend instead of auto locking and turning display off - same failure rate as turning display off, no dice.

Let me know if there’s any more info I could provide to help out. Any ideas?

Update - I modified my at one point to turn off the screen with xset dpms force off. Removing this line seems to have fixed the issue!

As a side note, a utility that diffs these configuration files from manjaro defaults might be useful for the i3 fork, could be useful for debugging like this!
