The screen back lights turn on but the screen remains blank after wake from sleep or lock.
I installed the KDE plasma DE and then the problem started happening on logout. I uninstalled it but it didn’t help.
If I lock and prevent the screen from turning off, I am able to prevent the problem.
I don’t know where to begin debugging the problem or the specific keywords to search for this. I am a relatively new Linux user.
Any help or leads here would be appreciated. I am happy to provide further details or log output as needed.
