Hey everyone!
I was just setting up Patchbox OS — everything went smoothly, and I set it to Desktop Mode. However, after rebooting, nothing appears on the Touch Display 2. Is that normal?
With the regular Raspberry Pi OS, the display works out of the box without any extra setup.
Does anyone have an idea what might be going on?
Did Touch Display 2 display anything before rebooting?
Try installing latest software updates via APT and rebooting:
sudo apt update
sudo apt upgrade
Nope, nothing at all. Let me try to update and see what happens. Thanks.
@fat_ima95 Any news here?
I ask because I tried to boot up PatchboxOs on a RPi 3B in Desktop Mode with a screen via HDMI and the screen keept blank except for a hyphen at the left top corner.
@Giedrius : Version of PatchboxOs: Patchbox OS Bookworm ARM64 2024-04-04. And the system was up to date.
Sorry, not yet. I will respond here as soon as I got time to test it.
There is nothing specific to Patchbox OS in regards to display configuration, I would suggest going through the available config options in config.txt and cmdline.txt and playing around with them directly or through sudo raspi-config:

Thanx for this answer. I’ll take a look. 
I finally found the time to connect the Raspberry Pi, and your advice fixed the problem. Simply updating and upgrading solved it — the Touch Display 2 works now. Thanks!
Yeah, sometimes new hardware devices get released (or have their software fixed up) after the Patchbox OS image is built, so updating the OS packages which are made up from the same set of packages as Raspberry Pi OS, usually helps.
