Radeon card on computer may is defect after current problems. How to check? sddm not start, card detected but no vram

My raddeon sapphire has 3 fans. These fans were only turning when had gpu loads to do. Otherwise, in reboot they were still. However, now all three fans working continously.

Display says null display. Sddm is stuch on logind message. My terminal "font" is the basic (large letters) and not the "high-end" font of a graphic card (small letters), as previously.

By the local current problems in Greece (due to fires and heat), i dont know if my graphic card has problem or not. I cant find any util to test its "integrity".

I have gpu utils. It is detected by system as radeon but what else i can do to see if it can work or it is for trash?

  • Sddm says is starting but no display in tty7.
  • gpu-chk utils says all green and some oranges
  • most test utils must open a display to test graphic card gpu infoinxi info

UPDATE 1: I changed from sddm to lightdm display manager. However monitor started to low resolution (1080x -75hz). It appears that i cannot change it

UPDATE 2: radeonontop when using glmark2 and glxgear is all values "0". It appears that GPU is off. VRAM is not detected by radeonontop

it appears that only some very basic display things is working from radeon card :(

See my whole dmesg (nothing of value) here

my /etc/modules contains only AMDPowerProfiler

SOLUTION led by Artem S. Tashkinov running sudo modprobe amdgpu but it was not permanent

i found out that for some reason, amdgpu was blacklisted in my system at etc/modprobe.d/blacklist-amdgpu.conf.

I dont know neither the reason nor the process that led to that. However, after commenting the line, it was fixed. Thanks.

  • Edit your question and post sudo dmesg | grep amdgpu output. Jul 24, 2023 at 15:46
  • nothing is displayed... about amdgpu sudo dmesg | grep amdgpu - added my whole dmesg, nothing of value Jul 24, 2023 at 15:51
  • Your Linux kernel (installation) is broken or you forgot to compile the module. The amdgpu module is required to drive your GPU. wiki.archlinux.org/title/AMDGPU What does sudo modprobe amdgpu return? Jul 24, 2023 at 15:54
  • @ArtemS.Tashkinov, It was working!!! I used it months. But now.... not... I dont know if some config or other file has been corrupted - how can i find? I am trying to find utils that test GPU / graphic card integrity directly. I cannot remember if amdgpu was installed or not Jul 24, 2023 at 15:57
