On Linux Mint 18.3 64-bit with MATE 1.18 running on Lenovo ThinkPad L470 laptop I’m experiencing the blank screen after detaching the laptop from a docking station. Usually the scenario is like that:
- laptop is sitting on a docking station and after longer time the screen goes blank according to power saving rules
- I’m detaching the laptop from a docking station while the screen is blank or I’m closing the lid and then detaching
- the laptop’s screen stays blank and looks like frozen or like it cannot wake up from sleep mode
I’ve got a monitor connected to the docking station and I’m using 2 screens when laptop is docked. And sometimes I’m experiencing an other variant of the problem:
- after undocking the Linux Mint is behaving like still having 2 screens thus I only see windows that were on laptop’s built-in screen before undocking
Solution
In both described scenarios this single solution helps:
- Press
Ctrl+Alt+F1
- Wait for the text console login prompt to appear
- Press
Alt+F7
That’s all 🙂
