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.

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.

AMD Ryzen 5 5600G requires kernel 5.14, as minimum level.
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. Thanks a lot! -- Carlos F Lange Gaúcho nas Pradarias https://sites.google.com/site/carlosflange/
