Intel UHD 620 graphics not working properly on Rocky Linux 9

[Anassanu]

Hey all, I dual-booted Rocky Linux 9 with Windows on my Dell laptop (Intel UHD 620), but I’m stuck with llvmpipe (software rendering) and my external monitor (HDMI) isn’t detected.

• Removed nomodeset after install, rebuilt GRUB
• lspci shows Intel GPU, glxinfo still shows llvmpipe
• xrandr shows only a “default” screen, no HDMI/eDP outputs
• Tried setting up modesetting in /etc/X11/xorg.conf.d/
• Switched to X11 (disabled Wayland), no change

Anyone got this working on Rocky 9? Or should I try Fedora or something newer?





Thanks!

We run quite a bit of Rocky, It's probably installed on over 200 systems here. I will say none of them are dual boot, but I don't think that should matter. I don't ever do anything with the modeset, I just leave it default. In Rocky 9 I've had much better luck with Wayland than legacy X11.

Fedora will give you newer drivers, newer kernels, and newer versions of software, that could help, but really I don't have these problems with Rocky 9.

Thanks for your help Brian! I have both installed but still get the error message. Is 8.7 not compatible with the intel-media-driver? [abc@localhost ~]$ sudo dnf install --nogpgcheck https://dl.fedoraproject.org/pub/epel/epel-release-latest-$(rpm -E %rhel).noarch.rpm Last metadata expiration...

You won't have to do any of this for Rocky 9 or Fedora. The dynamic kernel modules are already included.
