I just installed Slack again, and in my terminal (actually, everywhere), the display is wanky. In the terminal, all the text is fine, but it's about an inch left of where it should be. In WM all I can see is the top-left area (though I can still see the context menus).
Also, my mouse doesn't work. I configured it for PS/2 and all, but I can't get it to work. Argh.
[edit]
On a lighter note, I did get my internet configured properly on the first try this time.
