I am running Ubuntu 20.04 and my computer is freezing solid on the login screen. Have to hard reset holding the power button.

Initially, I had Mate 20.04 installed (I believe in April) and it worked great till Aug.

I have since tried several full clean installs (Actually new OS on / and keeping my same personal data on /home). All new installs fail to get past the login screen.

Currently, I am trying Ubuntu (not mate) 20.04. It will boot if I place this command in the boot grub: "intel_idle.max_cstate=1", but then the cpu n fan run constantly.

I have tried adding "dis_ucod_ldr to teh /etc/default/grub, as it has been linked to freezing on Intel UHD 620 cards. I have also updated to the latest EFI bios... no impact.

I am currently using the latest ubuntu kernel 5.11.0-36-generic But have the same issue using various 5.4 or 5.8 kernels

I believe the following may be helpful. It is what I get when booted using "intel_idle.max_cstate=1"

Thanks Mark

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
