I have just installed Ubuntu 20.04 on a new build with the following hardware:

  • CPU: Intel i5-10400
  • Integrated Graphics: Intel UHD 630
  • Motherboard: ASRock h510m-ITX/ac
  • RAM: Corsair LPX Vengeance 16GB 2666MHz
  • SSD: Crucial P2 500GB

I have been unable to get any graphics output to work unless I add nomodeset to my kernel parameters - whenever it boots up the screen simply turns off after the ASRock logo, and does not respond to any keyboard input (I can't even switch to a tty).

This includes on the Live USB installer, which I had to run in "safe graphics" mode to install. I have also tried the 20.10 Live USB, and even Manjaro (GNOME 20.2.1), both of which had the same issue.

If I use nomodeset then Ubuntu boots normally, but I believe this disables any hardware acceleration, and I'm unable to change the display resolution, so I am looking for a proper fix.

Checking the journal (I can log in via SSH) I see that GDM fails to start:

Mar 21 15:20:32 colin-desktop gnome-shell[901]: Failed to create backend: No GPUs with outputs found
Mar 21 15:20:32 colin-desktop gnome-session[830]: gnome-session-binary[830]: WARNING: App 'org.gnome.Shell.desktop' exited with code 1

Mar 21 15:20:32 colin-desktop gdm3[781]: GdmDisplay: Session never registered, failing

And that the Xorg server exits, with error messages from /var/lib/gdm3/.local/share/xorg/Xorg.0.log:

[     9.404] (EE) modeset(0): No modes.
[     9.406] (EE) Screen(s) found, but none have a usable configuration.

[     9.406] (EE)
[     9.407] (EE) Server terminated with error (1). Closing log file.

If I enforce the intel driver via a configuration file in /usr/share/X11/xorg.conf.d then Xorg reports a segmentation fault instead, but the overall effect is the same - no screen!

I have tried various fixes, but none have worked (I'm happy to try these again in case I got something wrong though!):

  • Adding i915 and intel_agp to the initramfs (suggested by the Arch Wiki)
  • Various configuration options in /usr/share/X11/xorg.conf.d
  • Updated drivers from ppa:oibaf/graphics-drivers and ppa:kisak/kisak-mesa
  • Installing a newer kernel (5.11)

I would be very grateful for any help that anyone could offer.

Thanks!

I solved this problem by installing a recent oem kernel (linux-image-5.10.0-1019-oem) which contains a fix for this issue, as suggested in the answer to this question: Blank (no signal) display on new ASUS Z590 motherboard

  • I am so thankful for your thorough documentation.

    I faced the exact same problem and went through the exact same steps as you with an Intel Core i3-10100 and an ASRock H510m itx a/c . Updating the Bios to 1.6 didn't help, but your suggested OEM Kernel works just fine! Thanks!
