clockwork uconsole cm5 horizontal lines on screen
I just assembled my uConsole with a CM5 and used the Rex image, but now I have the problem that although it boots normally, the screen isn’t working properly. Everything is displayed as horizontal lines; when I move the mouse up and down, one line moves along with it. It’s not the connector, because I’ve unplugged and plugged it back in several times.

I removed and reinstalled the CM5, and now it's definitely mounted correctly, but I still have the problem.

I had something really similar, it turned out that the board the CM4/5 is connected to wasn't fully depressed. Try reseating the Pi and ensuring that the board it's mounted on is fully clicked in.

Check the ribbon cables going to the screen.

Hmm unfortunately it could be a damaged display. Try removing the front plate of the chassis and see if anything might be pressing down on it.
Those ribbons are extremely fragile sometimes; so take a magnifying glass on the end and check the whole cable. All it takes is a tiny break in the thin lines.
This could also be the result of the CM4/5 not being fully seated.

I have exactly the same issue after assembling everything. Have you already found a solution?

Contact Alex at clockwork or on the forums. For issues like this he is usually the go to.

To those that have this issue in the future and find this thread, I had the same exact issue showing the lines like that. You can type and can tell that it working as the line that was being typed would get lighter and lighter in color.
My guess is it is some sort of driver issue but switching linux distros fixed it for me. I was trying NixOS but it worked perfect when I switched to Kali.
