Few days ago my Radeon RX 5700 after 3 years of working absolutely fine, kind of stopped working. The symptoms are: - At BIOS and GRUB there is video output. - If I run the system with "nomodeset" kernel option, then there is video output (obviously without acceleration and limited to low resolution). - It's not a faulty cable, because I tested it with other cables. I usually use HDMI cable, but with DisplayPort it's the same. - It's not a faulty monitor, because I use it also with my laptop on a second input. - If I put my card into another computer with Windows, it works with acceleration, like there's nothing wrong. - But if I start my Tumbleweed with amdgpu drivers, then as soon as kernel loads drm driver (so it's even before Xorg starts), the screen goes blank (the monitor shows "no signal" and shuts off). It doesn't matter if I boot my Tumbleweed with current or previous kernel. It doesn't matter if it's my Tumbleweed or a Leap 15.4 booted from usb stick. dmesg: https://paste.opensuse.org/pastes/c4df53bb0f7a It says: amdgpu 0000:09:00.0: [drm] Cannot find any crtc or sizes Xorg.0.log: https://paste.opensuse.org/pastes/e9bd760602d1 It says: (WW) AMDGPU(0): Unable to find connected outputs I also tried: - remove "quiet", remove "splash=silent", and append "plymouth.enable=0" (as written at https://en.opensuse.org/SDB:Nomodeset:_Work_Around_Graphic_Upgrade_&_Installation_Obstacles) - nothing changed - amdgpu.dc=0 - screen stays on, but shows nothing (just black) Anyone has any ideas what to do next?
