Ubuntu 20.04 freezing on Dell Latitude 3410

tr flag

I have a Dell Latitude 3410 that contains 4-core Intel i7 processors, 16 GB RAM and integrated Intel graphics drivers. I have installed Ubuntu 20.04 LTS (with 5.4.0-84-generic kernel) on this machine. One thing I have noticed is that laptop is unable to wake up when it goes to sleep or suspend states. I have to reboot the machine to get it to work. Sometimes it hangs like with a black screen after 2 or 3 hours; on some other occasions, it freezes after more than 20 hours.

As per Dell's advice, I ran various hardware tests to ensure hardware is fine. Software seems to be the issue. I have tried various solutions such as upgrading BIOS to the latest version, adding a line (GRUB_CMDLINE_LINUX="nouveau.blacklist=1") to /etc/default/grub. Nothing seems to fix the problem. How to resolve this? Please advise. Thank you!

BTW, I have disabled secure boot and the fingerprint sensor as well.

I have freeze issue at the login but would be able to boot in by going to the recovery mode and then resume (via grub menu, advance options for ubuntu <kernel version>). For me it seems like some conflict while loading the network drivers as when I boot via the recovery mode route, I don't have control for brightness. Is it the same issue you are facing?

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.
