Public bug reported:
Upon updating to linux-5.p.0-37 this morning, it asked me to restart,
and when it did, all I had was a black screen. I could see the power
was on, because the power led was lit. I rebooted a couple times with
the same result. Then rebooted to single user, did fsck, repair broken
packages, and rebooted, and it came up, but not using both monitors. So
I did another update of the packages, and rebooted. It was still black.
I ended up rebooting on the previous kernel, and it works now, and I'm
submitting this bug report using that setup. If it would be helpful, I
can reboot single user, and eventually get it up with only the laptop
monitor, and submit a ubuntu-bug report that way too.
Thanks for your great work on Ubuntu!
Rob
