Question: I accidentally deleted the top bar and now it will not save icons that I add to it.

I'll spend 5 minutes adding icons back only to find they disappear upon rebooting.

This has to be the strangest, glitchiest OS I've ever used. The icons are randomly changing positions on the bar, sometimes are half drawn or not at all, or spaced out unusually, or not there at all. What the heck? I just want a bar with my icons that doesn't change.

Answer: 
Try going to the "display" menu. (See image for more info)

From here you should be able to select your various connected monitors and change their resolutions. It should look like this:

If u like the terminal, then xrandr should do it. Look into various commands either in man pages or on the internet.

This worked for me. I put it in my `.bashrc` file, so whenever I want 1080p, I type `go1080p`.

```
alias go1080p='xrandr --newmode 1080p2 148.5 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync +preferred ; xrandr --addmode DVI-0 1080p2 ; xrandr --output DVI-0 --mode 1080p2'

```

I’m using DVI-0, but you can type `xrandr|grep connect` and look at the names it uses.
