Graphic card (RX 5500 XT) problem

Hi, guys

I have some problem about my AMD graphic card. As long as I open video in website, the screen always goes dark for like two second, then resumes. After I check the ‘lspci -v’, I find that there is no ‘Kernel driver in use:’ in my AMD RX 5500 XT. And I do installed the latest xorg-x11-drv-amdgpu. Is there any thing I can do? Thanks!

Is this a dual-GPU machine? Do you also have Intel stuff running?

By default, the Kernel contains AMDGPU drivers to allow AMD cards to be used, so it is strange that your card is not showing an active driver in use.

What is the output of the below?

  1. $ fpaste --sysinfo
  2. $ rpm -qa | fpaste
  3. $ sudo lspci -vvv | fpaste

Hi, Striker

emmmm, No, it’s not dual-GPU, and I don’t have any Intel stuff (maybe).

Here is the output:

Thank you for your attention !

Do you know why you boot with the nomodeset kernel parameter?

emmmm, I don’ know…Should I?

I think I remember a time when nomodset was a standard kernel parameter fedora was using, but can’t remember when that stopped. Could it be left over from an old kernel that survived upgrades? I’ve been upgrading for a long time and I don’t have that, so maybe not, but if @wangtairan doesn’t remember adding it manually, then that’s one idea.

You can use the grub boot interface to remove that on boot, just as a test, if you want. Let me see if I can remember: hit a key before the kernel is automatically selected, hit ‘e’ for edit, use the arrow keys to get around to that text in the kernel parameters and delete it, then hit ctrl-x to boot using those new options.
