Justin Yes, It happens although lockups are not random, It happens when the laptop is under heavy load.

      Justin I don't think I get out of memory nor hammering the CPU. If I run all those things(Godot development in VSCode, Discord in firefox and nautilus) at a time in 4.9, it only covers 4 GB(out of 8GB) ram and 40% of all cores.

        Wifi is working fine for me, but I have some freezes sometimes. Im using the 5.5.3 kernel. Maybe updating it to 5.5.4 may fix the problem?

        I am using intel hd graphics btw

        The issue is with Intel's drm/i915 code. It's an upstream issue they addressed in 5.6 RCs and AFAIK they have not done stable backports to 5.5 for it yet. The code is not in for 5.5.4.

        It's not in our hands. Unfortunately I have literally zero influence at Intel, otherwise I'd probably make it more like AMD 😛

          JoshStrobl I went back to 4.19 lts, but the freezings still there, is it a kernel issue then or no? also, thanks for answering too fast!

            May want to take a look at updating the bios, if an update is available. It helped me with some issues I had on my laptop.

            3 months later

            Hey, so this is not for that specific update but the same issue on 5.6 (current). When doing something graphics intensive (like playing 3d scene in godot) 2/3 times whole thing locks, i can see mouse mowing but i cant interact with anything etc. I tried installing lts kernel and while everything appears to work well, objects in 3d scenes are not displayed at all. Just an empty window with background. I tried unistalling xorg-driver-video-intel but that doesn't seem to do anything. Is there anything else i should remove/ install, any file i should regenerate? I'd be fine with either stop 5.6 kernel from locking system or 4.9 displaying 3d objects...

            EDIT: issue for 3d objects not rendering on 4.9 lts kernel seems to affect only OpenGL 3.0 as switching renderer in godot from GLES 3 (OpenGL 3.3) to GLES 2 (OpenGL 2.1) fixes the problem.
