External monitor flickers constantly

I just installed the 2nd memory stick, tuned to 4k60, not a single flicker!

Just to chime in on this for anyone else, I had a serious problem with image tearing when using fractional scaling on Linux (thread here). I also had the external monitor screen flicker problem. I didn’t put the two together.

I moved to two RAM channels (added the second stick) based on some reading around the Xe GPU and how much it likes symmetrical memory. That solved (more or less) my tearing issue, but I didn’t think to check for effects on the flickering. I just tested and sure enough, my flicker went away, too.

It looks like the Xe GPU really likes symmetrical memory, at least with the Linux drivers.

So, maybe the Framework team should say this for their future customers to know & order 2 memory sticks?

Beware, if you want to run linux on your framework, better get 2 memory modules, because it saves you tons of headache (no matter if you’re a wayland or x11 person)

For folks on Ubuntu, I upgraded to Ubuntu 22.04 (the newly-minted LTS) this morning, and am mildly surprised to see a significant improvement in my external monitor: no flickering or black-outs … even with single-channel memory (1 32GB stick).

So far it’s only been a few hours, but the external monitor has been rock-solid. And my second memory stick is set to arrive later today (classic timing), but this is working for me right now.

I can confirm that two memory modules completely fixed the issue for me.

Hello, I don’t know if its okay to reply to an over 2 year old post, but if its not, I’ll open another Thread.

Has anyone found a definitive solution for the screen flicker yet? I have installed a second RAM module after I found this thread and the flicker disappeared almost completely. I still have about 3-4 black screens per day (using only one RAM stick this would have been every 5-10 seconds) and the occasional horizontal graphical glitch.

The problem was present with the official HDMI/DP adapters and the OWC dock I’m using right now. I have a 1440p screen that is set so 120hz.

Some system information:

Info

Operating System: Manjaro Linux
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.1
Kernel Version: 6.12.4-1-MANJARO (64-bit)
Graphics Platform: X11
Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz
Memory: 31,1 GiB of RAM
Graphics Processor: Mesa Intel® Xe Graphics

Sure okay to ask!

In my case, the random system freezes (both on Linux and windows) were caused by a broken WiFi card.

Look for system logs pointing to errors regarding this, maybe this could also be your problem, but the old rule goes „remove all the stuff until your issue is fixed“, so ymmv!

Great thing with framework is you can actually do this!

So you might thus remove the WiFi card and work on Ethernet for a day and see whether that helped!

I just experienced this on my framework 16 that I got a week ago. I get no screen flickering plugged into the dgpu 7700S but on any usb-c port which im assuming are outputting the igpu ryzen AI 350 i get crazy flickering. 4k 144hz HDR screen and I also have 1 ram stick. I also have no issues when plugged into a thunderbolt dock. it also goes away when i lower the refresh rate to 120hz

I’m running fedora 44 with KDE plasma and wayland
