Followup: HDMI to any monitor/TV shows a blank screen, but is detected

@pobrn @Fabby

Is there anything I can do, even if it’s distro hopping?

I don’t understand why, no matter what I try, it just never enables prime sync. This thing is supposed to have a 144hz refresh rate but i only see 60 available. my EXTERNAL monitor is 240hz, and it shows that in xrandr.

Is there anything else that I can do… maybe open source drivers of some kind… cause I don’t like proprietary to begin with.

Please, we’ve gotten this far… which is further than I ever would’ve thought… and also, I remove optimus-manager now – it did absolutely no good and the configuration regarding nvidia is kinda ignorant… it’s as if configuration doesn’t get picked up or something, but it still seems to be picking up that I put one Separate screen section for each display (or, more accurately, an extended display) … so i have to wonder how i can get these settings saved and WORKING. I’m sorry but if others here have the same hardware and the same drivers with the same CRAP then why the hell wouldn’t it work on my end? it makes NO sense :frowning:

Please excuse the tantrum, I’ve just had it… I’ve tried so much it’s insane; I haven’t worked this hard in my life…

Start from scratch and reinstall and use KDE instead of cinnamon if you have the RAM available. (You never posted a full inxi --admin --verbosity=7 --filter --no-host, so can’t tell)

Ensure the monitor (and any other hardware you’re going to use) is attached to the system while you’re reinstalling.

You now know more about Manjaro and how hardware detection works, so this time you should be fine…

That’s all the last-minute, ultimate, nuke it from orbit advice I can give…

Yeah I’m going to try a different DE and might try starting from scratch. I think I need to get rid of Cinnamon, which might be the damn problem in the first place… I went back to the configuration someone posted awhile ago for someone with similar hardware. You were right, though… this internal display is AMD only… I was re-reading before I saw your response, but it’s possible the DE is the problem, and it seems to point to it. I could be wrong but we’ll find out. And yes I have learned enough about mhwd lol.

Thank you for your help though. You’ve been fabulous and I will be updating you on my little start from scratch journey :face_with_raised_eyebrow: lol. Alright… I’ll let you know when I’m able to do so… gonna back some stuff up. At least the rest of it works… it could be worse…

29 days between your first post and this one. I must’ve missed it scrolling through the history…



Yeah, it made no difference one way or the other… usually plenty of ram, there are crashes here and there that are inevitable:

I’ll try… GNOME3 or MATE for my next shot. and if PRIME doesn’t work, I’ll go to KDE. There are solutions for this stuff, it seems, with KDE. But I do have a question, @Fabby or @pobrn – a quick question… Does Manjaro handle more than one DWM very well? I know it works in Ubuntu but can be a bit dangerous and lead to dependency hell. Thoughts on this? I’m… moderately “experienced” but nowhere near the knowledge that you both have.
