After upgrading to 21.04 my notebook freezes in login screen. If I start without gdm, the message I see in console is "Topaz is not supported in kfd" It works fine with 'nomodeset' in grub. My graphics card is: Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445 / 530/535 / 620/625 Mobile]

Is it a misconfiguration or wrong driver installed?

Thanks in advance.

  • How can any one know, you never said what driver is installed.

  • I have the same warning with a Radeon M445, it’s just a warning, nothing more; it’s probably unrelated, because my GDM works fine… in Wayland and Xorg.

  • Presumably, your laptop has an integrated GPU also? I have Intel HD Graphics. It’s possible the fault lies there instead. Is your BIOS up to date?

  • I added the output of "lshw -c video" and will look for a BIOS update.
