Black Screen after wake from suspend on Ubuntu 21.04

I have a Dell Venue with an Intel CPU and Intel HD graphics card. After I suspend my PC and wake it up, the screen remains black. I can listen to the sound when I press, for example, the volume buttons, but I can't do anything.

I've already tried the following, but nothing worked:

  • Switching gdm3 to lightdm.

  • Replacing gnome-screensaver with xscreensaver.

  • Updating the kernel from 5.11 to 5.13.1.

  • Ctrl+F1 or Ctrl+F2/F3

  • Adding:

    nomodeset / nouveau.modeset=0 / nouveau.blacklist=1 /pci=nomsi

    to GRUB_CMDLINE_LINUX.

  • Changing the power button function from the settings.

If I disable the s3state (sleep state) from the BIOS, it works, but the PC doesn't sleep normally and it continues to drain battery.

Info that may be useful:

  • The BIOS is updated.

  • To boot correctly, I set the following string in GRUB_CMDLINE_LINUX_DEFAULT:

    quiet acpi_osi=Linux nomodeset acpi_backlight=vendor splash

    Without nomodeset, Ubuntu doesn't boot. Without the rest, it is impossible to regulate the display luminosity.

  • Hibernating and waking the PC up using a live Ubuntu USB seems to work.

@karthiknair thanks for the reply. So I deduce that we will have to wait for a fix and in the meantime use it without the possibility of suspending it.

@Perti If you want to know how to kill the "suspend" feature altogether even when you close the laptop lid, I have a workaroud here https://askubuntu.com/a/1336041/1227056

@karthiknair thanks, but for now I have already killed the suspension process by disabling the s3 state from the bios

I don't have much to add but I will say this. I chased every rabbit hole I could find w/power settings because my Kubuntu would wake but just have a black screen, never allowing me to log back in forcing me to restart.

It turned out to be my themes were broken. I found an obscure site on how to fix it, but ultimately I end up just resetting my themes back to normal and it fixed it.

I also have the same problem. How do you know whether it is because of a broken theme and how to reset to default?

I also have a Dell Venue - to be precise, a 10 Pro 5056 with an Atom Z8550 (Cherry Trail generation). These chipsets have freeze-after-sleep issues with the most recent kernels.

I've tested several kernels, and the stable ones regarding suspend are the 5.4 series. I'd advice installing a 5.4.1xx to have a recent enough and working kernel. Download from the Ubuntu kernel archive at https://kernel.ubuntu.com/~kernel-ppa/mainline/ - one needs 4 files, linux-headers-5.4.1xx-, linux-headers-5.4.1xx-generic, linux-image-5.4.1xx-* and linux-modules-5.4.1xx-. Download and use sudo dpkg -i linux

Also with these chipsets, sound is often an issue. I ended up using a USB-to jack adapter/sound card. Because even when sound was "sort of working", there was stereo issue.

Another issue is setting brightness, which has a huge impact on battery (altering /sys/class/backlight/intel_backlight/brightness). With some kernels, the backlight brightness cannot be changed and the battery lifetime is killed; only gamma can be set using (like xrandr --output "DSI-1" --brightness ).

List of kernels I've tested:

  • 5.4.53 brightness OK suspend OK sound OK not after suspend

  • 5.4.60 brightness OK suspend ?? sound NO

  • 5.4.75 brightness OK suspend ?? sound NO

  • 5.4.100 brightness OK suspend OK sound OK (after a while when suspend)

  • 5.4.105 brightness OK suspend OK sound NO

  • 5.4.128 brightness OK suspend OK sound sometimes

  • 5.4.130 brightness OK suspend OK sound sometimes on 21.04 - boot failure on 21.10

  • 5.4.150 boot failure on 21.10

  • 5.6.15 brightness OK suspend CRASH sound OK

  • 5.8.18 brightness OK suspend CRASH sound OK

  • 5.10.1 brightness NO suspend OK sound OK

  • 5.10.2 boot failure

  • 5.10.3 brightness NO suspend OK sound OK

  • 5.10.4 brightness OK suspend CRASH sound OK

  • 5.10.10 brightness OK suspend CRASH sound ??

  • 5.10.15 brightness OK suspend sound NO

  • 5.10.19 brightness ?? suspend ?? sound ??

  • 5.10.35 brightness OK suspend CRASH sound ??

  • 5.11.20 brightness OK suspend CRASH sound ??

  • 5.12.15 brightness OK suspend CRASH sound ??

  • 5.13.0 brightness OK suspend CRASH sound OK

  • 5.13.1 brightness OK suspend CRASH sound OK

  • 5.13.13 brightness OK suspend CRASH sound ??

  • 5.14 brightness OK suspend CRASH sound ??

I wanted to look a bit more into this: actually the system does wake up properly, except the screen. One can verify that by typing in a terminal "sleep 10; reboot", suspend then wake up the laptop: it'll reboot nicely (journalctl confirms this). Also, using the "switch to external display" has the same behavior - the internal GPU will never resume sending the image to the internal screen. I see the backlight flashing when the screen wakes up, but it stays black.

thank you for your answer. Unfortunately i've tried 5.10.1, 5.10.3, 5.4.1 and 5.4.105, but the problem still remains. I really think there is no solution in my case

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.
