I got the infamous nividia ubuntu 20.04 machine won't come out of sleep/suspend

hu flag

Nothing works to solve it. I tried adding things to the grub file, with scripts, without. Can someone help me diagnose the particular problem of my notebook? It seems immortal.

I am with:

  • nvidia-driver-390

  • kernel 5.4.0-86-generic

  • ubuntu 20.04 - Gnome (vanilla)

  • I removed all blacklisted nvidias.

/etc/default/grub:

GRUB_DEFAULT="saved"
#GRUB_HIDDEN_TIMEOUT="0"
GRUB_HIDDEN_TIMEOUT_QUIET="true"
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`"
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="nouveau.blacklist=1"
#GRUB_CMDLINE_LINUX="nouveau.modeset=0"
#GRUB_CMDLINE_LINUX="acpi_osi=! \"acpi_osi=Windows 2013\""

sudo vim /etc/modprobe.d/blacklist.conf:

blacklist nouveau
options nouveau modeset=0

From dmesg | grep -i "nvidia\|suspend":

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.
