Hi,
I’m running KDE Plasma on Tumbleweed. This issue has existed from the beginning of Tumbleweed install about six months ago and my hope has been that one of the updates would fix it but it hasn’t happened so I’m reaching out for help. This is not a multi OS system. The issue is as follows: during boot process, when it’s time for the login screen to appear the monitor goes dark and “No Signal” message appears, then the monitor goes into standby mode. I can enter the user password while the screen is dark and after I hit Enter the desktop loads and the monitor wakes up. Everything is fine and well after that. Locking the screen or waking it up after a period of inactivity does not present the same issue, the login screen appears as it should. This only happens during initial boot process. Below is some data I was able to pull and I hope it’s useful. If other details are necessary please advise. I appreciate your help with trying to resolve this behavior. Please let me know if you have any ideas on how to resolve this.
