I wanted to try out Endeavour OS from a USB drive, and after Pop!_OS and Ubuntu, this is the first time everything worked (mostly), yay!
However, there’s one issue I have on one of my screens. Depending on what’s on the screen, part of my screen is filled with noise. In the video you can see that the noise changes when I scroll through my Firefox settings, or when I move my mouse. I also created a screenshot to check if it also contains the noise, which it does not. In the two pictures you can see that the noise changes location based on whether I have devtools open.
I have a P1 Gen 3 (type 20TH, 20TJ ) Laptop (ThinkPad) - Type 20TJ. Ports: 1x Mini Ethernet Connector (Convert RJ-45 by dongle); 2 USB 3.2 Gen 1 (Type A); DC-In; Smart Card Reader (Select Models); Headphone & Microphone combo Jack 3.5mm; FingerPrint Reader; Docking via Mobile Workstation Cable Dock; 2 Thunderbolt 3 (USB-C/DP/PD); HDMI 2.0; 4-in-1 Media Card Reader Graphics: 1x NVIDIA® T1000 4GB
I use the laptop’s own screen together with 3 external monitors at 4k@60Hz. One screen is connected to the laptop’s HDMI port, and two others through DisplayPort connections through a thunderbolt dock. The offending screen is connected to the dock, on I believe the second port (judging from the fact that this is screen #3 and the other dock-connected screen is #2 in Windows display settings).
On Windows 10 I’ve never had an issue like this. The only issue I had on Windows is that the same screen would sometimes lose connection when a webpage had a Spotify embed, or when I watched something in the Netflix app. If I then turned my PC to sleep and back on, the screen would turn on again.
I appreciate any help I could get with this! Thanks in advance!
I tried X11, same thing happens. I also ran nvidia-inst, which installed the -dkms version instead of -lts for some reason, but it didn’t change anything.
I thought maybe it doesn’t like my fractional scaling so I changed everything to 100% and rebooted, but also didn’t change anything.
I made a screen recording of me scrolling down a page. While scrolling I had several display noise issues like in the video in my original post. In the screen recording you can see those frames are skipped, causing stuttering in the recording. Would this imply a hardware issue after all?
Try a different DP cable. If you can, use a 1.4 or 2.0/2.1. It sounds like there may be some signal degradation.
I just swapped the cables at the dock, so plugged them both in the other port, and the problem moved to the other screen, so it’s probably related to the 2nd DisplayPort connection. Scrambling for ideas rn.
