Turning off modesetting basically disables the driver.

Well, in my case, I was using the radeon.modeset=0 variant to rule out
issues in x.org. And in my case x.org did start still, albeit with a
jacked-up resolution.

But in Laszlo's case, x.org gets "puzzled" too.


Maybe your distro's xorg has some generic vga fallback method. I am not aware that mine (Debian Testing) has one.
BTW I use Debian Testing (xfce) and glamor (compiled from git) so i need a specific xorg.conf.


Using "nomodeset" or radeon.modeset=0 tries to use the deprecated user mode setting, which in your case isn't even supported by the driver.

Please provide dmesg logs with drm-debug=0xe instead.

Thanks in advance,
Christian.
