Hmm I am sorry that it did not help. You could try pressing e in GRUB and adding “modprobe.blacklist=radeon modprobe.blacklist=amdgpu” to the end of the linux line. > I copied > the whole /var/log folder so I'm attaching zip-compressed folder below. /var/log/messages looks normal to me. /var/log/messages shows xorg-server-vt8 started at > Jul 24 03:28:56 localhost shepherd[1]: Service xorg-server-vt8 has > been started. so you waited for 90 seconds until you pressed Sysrq+E or Sysrq+I or something at: > Jul 24 03:30:26 localhost vmunix: [ 97.542387] sysrq: Terminate All Tasks If everything had worked, you should have seen SLIM. /var/log/Xorg.0.log shows that no working graphics driver was found. However, since /var/log/messages looks normal, I suppose this is an old log file (?). Has booting (not necessarily installing) an official Debian USB installer (i.e. without nonfree firmware) or another libre distro worked previously? > And also a strange thing happened - don't know if it's related, but > after switching my system to "UEFI mode" screen resolution using > linux-libre, which was really low, now changed normal (as on systems > with blobs loaded). I see this wrong resolution too when running the installer in old BIOS mode. Your config shows grub-efi-bootloader, so I suppose it can only boot in UEFI mode (?). Maybe not booting in UEFI mode runs a wrong bootloader (?). Regards, Florian
