Hi everyone, I just installed Debian Buster with KDE Plasma on a notebook that has an AMD Radeon 6490M and an Intel HD Graphics 3000 installed. The installation (text-based) worked fine, however, after rebooting, I just get a tty, X won't start. When checking dmesg for any errors, I found:
[drm:radeon_pci_probe [radeon]] *ERROR* radeon kernel modesetting for R600 or later requires firmware installed Xorg furthermore listed errors like this: [ 14.666] (II) FBDEV(4): using default device [ 14.682] (II) modeset(G0): using drv /dev/dri/card0 [ 14.682] (EE) Screen 0 deleted because of no matching config section. [ 14.682] (II) UnloadModule: "radeon" [ 14.682] (EE) Screen 0 deleted because of no matching config section. [ 14.682] (II) UnloadModule: "modesetting" [ 14.682] (EE) Screen 1 deleted because of no matching config section. [ 14.682] (II) UnloadModule: "fbdev" [ 14.682] (II) UnloadSubModule: "fbdevhw" [ 14.682] (EE) Fatal server error: [ 14.683] (EE) Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices So I searched the internet and found several <https://joshtronic.com/2017/11/06/fixed-radeon-kernel-modesetting-for-r600-or-later-requires-firmware-amd-graphics/> sources <http://blog.ataboydesign.com/2017/10/04/error-radeon-kernel-modesetting-for-r600-or-later-requires-firmware-amd-graphics/> that <https://superuser.com/questions/1289728/fresh-installed-debian-9-is-bootin-into-black-screen> recommended installation of |firmware-amd-graphics| from non-free. I installed that package, but afterwards the system won't boot at all - it only displays "loading initial ramdisk" and then the screen goes black. Any ideas on how to get graphics output on that machine? I don't even need the radeon graphics, the integrated Intel graphics would be okay for a start as well. My full Xorg.0.log <https://termbin.com/x15x> and my dmesg <https://termbin.com/uc85> are attached here <https://termbin.com/x15x> and here <https://termbin.com/uc85>.. Thanks a lot in advance for any ideas! Kind regards, LuKaRo
