I'm booting Sparkylinux from a live-usb in a notebook with broken screen.
There is a external monitor connected by VGA. The external monitor is booted dual with the notebook monitor And the external monitor resolution is booted with some issues.
To fix it i need to put the external monitor as the primary monitor, or even better, shutdown the notebook monitor. In Ubuntu i can use Fn key to change monitors.
In Lubuntu, even i cant see much, i can open the start menu, type
monitor and change it manually.
In Sparkylinux the special key dosen't work and start menu is tricky, so i cant access the monitor menu whithout seeing.
So I'm trying
xrandr to change it , but apearently i cant open the terminal ( ctrl+alt+t), the bad resolution sends it to another realm.
So i used ctrl+alt+F1 to try
xrandr, but for most but not all
xrandr commands i get
"xrandr: Cant open display".
