After resuming from suspend computer freezes

I hope to find help about this problem: Everything remained fine after i installed Ubuntu approx. two years ago,but after resuming from suspend after a recent update and restart from a couple of days ago, my computer freezes. There is no reaction if I push any key with my usb keyboard, the lights for numlock and caps lock on my keyboard do not react and the display of my two monitors remain black. I did not change anything else than installing a regular system update, like I do every week. I did not customize the suspend settings in any way except in the gui settings menu.

Also when I start memtest it freezes after 1 second (00:00:01). Resuming from suspend in Windows and Ubuntu 16.04 LTS (Live CD) works fine. Memtest86+ 5.01 from UBCD (Live CD) works also fine without errors (Pass 1).

I tried different gpu drivers:

  • X.Org-X-Server: suspend does not work, instead my session gets locked.
  • NVIDIA driver metapackage...390: suspend does not work, instead my session gets locked.
  • NVIDIA binary driver 340.108: suspend does not work, instead my session gets locked.
  • My default driver is the recommended one (NVIDIA driver metapackage...470, tested).

About my computer:

  • OS Ubuntu 20.04.3 LTS Dualboot with Windows
  • Mainboard MS-7752 (To be filled by O.E.M.) Z77A-G45 (MS-7752)
  • CPU Intel(R) Core(TM) i5-3450 CPU @ 3.10GHz
  • GPU NVIDIA GK106 [GeForce GTX 660]
  • PCI CMI8788 [Oxygen HD Audio]
  • PCI FL1100 USB 3.0 Host Controller
  • SSD 250GB Samsung SSD 850
  • Memory 2x 4GiB DIMM DDR3 Synchron 1333 MHz (0,8 ns) + 2x 2GiB DIMM DDR3 Synchron 1333 MHz (0,8 ns)
  • Swap is not configured

Please help me to find what part in ma OS is faulty for that and how can I recover/repair it.

Most probably your GPU. The GTX660 is rather old, so you would need an older nvidia driver for it to work. Be aware that the driver must fit the kernel. Which NVIDIA version do you run? `nvidia-smi` should tell you.

Ok, that is the same driver I'm using with a GTX760. This combination works on my hardware for suspend as well as hibernate (it never worked on a laptop). My current kernel is 5.4, so in case you've got a newer one, you might select an older kernel. The only other idea is to remove your sound driver (just to check) - Sorry I couldn't help you more, hence this comment and not an answer...

My kernel is Ubuntu 5.4.0-99.112-generic 5.4.162. Your comments motivated me think about it in a different way. I turned my Graphics Internal Device on and changed it from Nvidia to Intel® HD Graphics 2500 (IVB GT1). Now resuming from suspend works fine again. Maybe I will leave Ubuntu and use Windows again. Thanks for your comments!

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.
