Title:
laptop display is enabled even though lid is closed
Status in mutter package in Ubuntu:
Fix Released
Bug description:
Hardware: Razer Blade 15 with 3 external rotated (portrait) monitors.
Driver: nvidia-455
This problem occurs in Ubuntu 20.04 LTS. Ubuntu 20.10 works ok.
If I boot the laptop with the lid closed, "Screen Display" settings
shows the laptop display is active, and it's possible to drag a window
off the screen to where the laptop display is supposed to be (but lid
is closed, it's off).
If I then suspend and resume, the screen sizing gets messed up -
hitting F11 to fullscreen a window on the 2nd monitor results in it
expanding to fill 2 monitors instead of 1. However, if I open the
laptop lid, and suspend with the lid open, then F11 fullscreen
correctly fills 1 monitor as it should. I suspect this sizing issue
could be caused by the laptop screen being incorrectly included in the
screen size calculations.
Regarding Ubuntu 20.10 working, it seems 20.10 has the same Nvidia-455
driver, so I tested the 5.8.18 linux kernel with 20.04 to try and
determine if it was kernel issue, but the problem still occurred.
