This was a clean installation of Xubuntu 18.10 on my Toshiba Satellite C650 and the issue with the blanked screen NOT responding to Keystrokes or Mouse Events was observed during Installation and has continued since the clean installation!
With the Upstream Kernel I have the same problem with the blanked screen NOT responding to Keystrokes or Mouse Events and as with the stock kernel, my Laptop will unblank when I plug an External Monitor into the Laptop's VGA Port! With the Upstream Kernel there is NO /proc/version_signature, therefore I include /proc/version Linux version 4.20.0-042000rc2-generic (kernel@kathleen) (gcc version 8.2.0 (Ubuntu 8.2.0-9ubuntu1)) #201811121328 SMP Mon Nov 12 13:30:14 UTC 2018 I also tried an Ubuntu 18.10 Installation and curiously its blanked screen correctly responds to Keystrokes and Mouse Events! /proc/version_signature Ubuntu 4.18.0-11.12-generic 4.18.12 Now that I know there is a difference between Xubuntu 18.10 and Ubuntu 18.10, I will await instructions on whether to complete the instructions on Tagging the Upstream Kernel and the Bug being Confirmed... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1803268 Title: Ubuntu 18.10 after Blank Screen System Will NOT Unblank Status in linux package in Ubuntu: Incomplete Bug description: Toshiba Satellite C650 (embedded Intel HD Graphics 3000) running Xubuntu 18.10.
