Dell laptop will not wakeup after suspend

in flag

just done an error-free upgrade from 18.04 to 20.04.3, and found that my Dell 5559 Inspiron still won't wake up after suspend. Screen remains black, and all keyboard/mouse activity is ignored. Only option is to force a manual power down and reboot.

This has been an ongoing problem through several versions of Ubuntu, and I was under the (mistaken?) impression that the issue mostly affected Dell machines, but a search reveals problems with several other manufacturers.

This question (or variations thereof) has been asked many times (including on the Dell Community website), so there are a lot of answers out there; the solution that works for 20.04 seems to be to boot with an older version of the kernel (5.0.0-1070-oem-osp1 - my current version is 5.4.0-91-generic x86-64).

So my question is: why the heck would Canonical remove the functionality from a later version? And does anyone from Canonical participate in this forum? 20.04 apparently has 'long term support', so should I expect a fix for my kernel version? Or do I have to effectively 'downgrade'?

Cheers

Have you tried a clean installation?

How much RAM & swap to you have? Are you willing to learn, in detail, about suspend/hibernate, or do you just want to rant?

could you specify what type of installation did you performed?. are you used a type of gparted tool later ?

It was an upgrade, not a fresh installation. Followed the prompt. It's not a dual boot machine.

I'm happy to learn about hibernate/suspend; but I'm not about to reinstall everything in case it might fix it. Everything else works. Mem: 7.7Gi, Swap: 2.0 Gi. It's a core i5, so reasonably quick. I didn't use gparted, just upgraded.

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.
