I am using LibreOffice Writer for write a book about matrices in math, but when I start to typing on this application, my screen goes black with white dash blinking on left upper corner and displaying login screen.
My question is why this issue can happen on my laptop?. If it continues like this, I can’t use my old laptop comfortably for making documents, or anything that using LibreOffice wholly. I use LibreOffice from default installation of Linux Mint.
OS version : Linux Mint 21
LibreOffice version : 188.8.131.52
