Title:
external monitor disabled upon editing file with vim
Status in mutter package in Ubuntu:
Invalid
Bug description:
This is the strangest bug I've encountered in my 20+ years of linux use.
See a video of the bug at:
https://drive.google.com/file/d/1StYD5kbL5pLRBOc6V-TXuE5DgymTdM0R/view?usp=sharing
Using an external monitor I am editing a Snakefile with vim and syntax
highlighting. Under certain condition the monitor will go to sleep.
0. download the Snakefile, vimrc, and the colorscheme that are the attached
archive
1. move the colorscheme to ~/.vim/colors/
1. `vim -u vimrc Snakefile`
2. delete one of the quotes, and see the external monitor go into sleep mode.
Pertinent points:
- If I disable the custom colorscheme or disable syntax highlighting there is
no problem.
- If I move the gnome-terminal onto the builtin display, then the external
monitor reactivates.
I wouldn't normally report this bug because it seems so specific to my
setup. What is alarming is that a vim session in a gnome-terminal,
under certain conditions, can cause the monitor to go to sleep!
