--- Comment #13 from FrankNFurter <[email protected]> --- I'm still very unhappy about that. I filed some more info and a python testfile I used. Output of the testfile is: --------------------------------------- Found OpenCL plattforms: 0: rusticl - Mesa/X.org Used Plattform: rusticl Found devices: 0: AMD Radeon RX 470 Graphics (radeonsi, polaris10, ACO, DRM 3.57, 6.8.0-101-lowlatency) - ALL | GPU OpenCL kernel successfull! GPU is functional. -------------------------------------- Before this I tested a lot of different installations and version of amdgpu one can find at AMD website. I tested some of the usecases of amdgpu-install script but nothing will work. Without the -no-dkms switch the kernel module is build by the amdgpu-install script and after reboot even the screen stays black. So I have to uninstall them in recovery mode. I had some variants with amdgpu-install where Wayland login hangs but X11 works. :-( So I did not install these amdgpu things at the moment and my python test I did without amdgpu driver. I also installed phoronix-test-suite and run the gputest benchmark while watching radeontop. So I could see that the gpu was doing hard work. In digiKam, the OpenCL testoutput hangs where the line ' Q_EMIT signalNotification(i18n("Preparing face for feature extraction..."));' ends. This is the last message. The thread hangs. Because I am not able to debug I could not tell where exactly. There is no output in kernel log or journalctl -f . Any further support? -- You are receiving this mail because: You are watching all bug changes.
