As I said in previous post i'm not sure that this is the same problem as with me, but look very similar because of the Haswell Processor and I'm unable to get a working Desktop environment.
Same computer works just fine with Ubuntu 20.04, which have older kernel. My experience with Ubuntu 20.10 live is that it cannot boot every time and its locks up, but it boots fine in safe gfx mode. In safe gfx mode I installed it on clean disk, and when try boot it - sometimes just log into gnome shell and it locks up. Error in dmesg is i915 GPU hang. In wayland it works better so I can click on menus but sometimes it freeze for few seconds and continue( GPU reset) and when you run program that use xwayland it got a total lock up. I installed cinnamon desktop and it locks immediately after login, Cinnamon with software rendering works just fine. I tried Xubuntu it hang as well. With "nomodeset" kernel parameter it works fine but only in 1024x768, tested it with Ubuntu, Cinnamon and Xubuntu. So I search for solution and find this thread over FDO, with a lot of people with Haswell GT1 video having the same problem since kernel 5.6 I think. https://gitlab.freedesktop.org/drm/intel/-/issues/2024 Other peoples with same problem, also there are several threads over Arch linux forums https://bugzilla.redhat.com/show_bug.cgi?id=1843274 https://bugzilla.redhat.com/show_bug.cgi?id=1886438 My Processor is Intel Pentium G3258 AE and is Desktop CPU. Other components I think doesn't really matter in this case. and my errors from DMESG [ 31.037041] i915 0000:00:02.0: [drm] GPU HANG: ecode 7:1:8edcfc79, in gnome-shell [1441] [ 31.037044] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
