被選擇的解決方法

I would like to thank you for going out of your way to assist me. I have no idea what a compositor is. I followed your instructions and got this: ^[[200~echo $XDG_SESSION_TYPE~ echo: command not found Neither do i know what my environment is. I am on linux mint victoria 21.2---i think that is ubuntu. No idea what kde stands for, or gnome. Despite it all, i now have my two screens running correctly. The mouse moves b/w them, nicely. My logitech G910 keyboard does not always allow me to use the number keyboard to the right. the keys at the top always work, but # keyboard to the right works on and off. Num lock seems to mean nothing. And again, thank you for such a spirited answer!!!!!

Hi there, sorry to hear about your issue. This is not a thunderbird issue but rather something to do with your session. I have some additional questions to help root cause your problem.

  • Which distro (and version) are you using? Ubuntu, Fedora, something else?
  • Do you know which desktop environment you are using? GNOME, KDE, something else?
  • Which compositor are you using? Wayland, X11, something else? You can find out by going to the terminal and typing `echo $XDG_SESSION_TYPE`

Typically you would go into the distro settings and modify the resolution per monitor there.
