Hi all
My system are 65% of the time serving a black screen, after the kernel has been started through GRUB. I’m able to start tty2, and run systemctl restart sddm.service
. Hereafter the login-screen shows up in the tty2 session.
But I’m searching for a bit of help, to get this fixed. There’s a few brilliant threads on this forum, too. But sadly I’ve not found the proper commands and insights. Therefore I’m trying with my own thread.
Problem
After selecting the kernel in GRUB (normal boot), it’s ending with a black screen, insted of searching the login-screen.
How it’s currently fixed
By opening tty2, I’m able to call system restart sddm.service
and the login-screen shows, with no problem.

So, what can I do?
I would like to know that I can do, to fix this. The most wierd thing is, that’s it’s working on/off, I’d guess every 1/3 time or so (by booting normally, and login-screen shows on tty1, with no issues). By booting it multiple times, I’ve fixed it in the part - but normally it takes many reboots. Therefore I’m now going to tty2 instantly.

Hi @megavolt Thanks for the answer! It’s a bit fun, cause I’ve thought about a timing issue myself. However, it just didn’t work out in my head, maybe use to the lack of knowledge related to boot-up procedure and service start-ups with GUI-based elements. I must say, I forgot to share the most important information… With that said, everything works great - except for the wierd maybe timing-related issue. More details My system are a bit of a mixed bag, cause my Intel Onboard-…
