low resolution with new Ryzen 5 built-in graphics
I am trying to setup a new machine with oS 15.2, but it is giving me only a fall-back graphic resolution of 1024x768, even though the monitor has HD resolution. The graphics is built-in in the CPU: AMD Ryzen 5 5600G with Built-in Radeon™ Vega CU Graphics lspci describes the device as "[AMD/ATI] Cezanne", which sounds right. But KDE is only offering this poor resolution. Is there a way to achieve the higher resolution that the built-in graphics can offer? -- Carlos F Lange Gaúcho nas Pradarias https://sites.google.com/site/carlosflange/

It needs to be determined why. It's not KDE's fault. Likely 15.2 doesn't support a GPU that new, so you may need 15.3 or TW instead. Please do: cat /var/log/Xorg.0.log | susepaste and provide the resulting URL here. First, do: cat /proc/cmdline If *modeset* appears in the output, it needs to be removed from Grub. This can be done on a per boot basis by striking E at the Grub menu, then removing the entire string before proceeding. It's typical for the installer to insert nomodeset or a similar modeset string in order for the installer to function, but it becomes an insurmountable obstacle to optimal graphics on an installed system. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

AMD Ryzen 5 5600G requires kernel 5.14, as minimum level.

I've never had hardware newer than the distro to contend with. It might be enough to install from repositories/Kernel:/stable/standard/x86_64/ or the 15.3 kernel, but it might also require newer firmware or a newer xf86-video-amdgpu or even Xorg. I'd try the 15.3 kernel first, but it might depend on something incompatible with the 15.2 basesytem. If it won't install, I would expect the stable/standard kernel would. Kernel is the place to start.

Thank you Felix and Masaru. So, I added the repository: https://download.opensuse.org/repositories/Kernel:/stable:/Backport/standard... It not only gave me the 5.14 kernel in a way compatible with oS15.2, but it also offered several firmwares, including the xf86-video-amdgpu driver, as recommended updates. Essentially, I did not have to do any digging or searching for dependencies. I just had to install the newest kernel and the recommended packages. With that I gained full support of the new Ryzen 5 Built-in Radeon Vega Cezanne graphics in openSUSE 15.2.
