I've tried updating the kernel to bullseye-backports but that hasn't helped. It's using the modesetting driver. Putting nomodeset on the kernel commandline and that doesn't work. Forcing X11 to use the fbdev device does start but doesn't find any outputs.
I tried switching to use the uefi boot - which has the nice feature that grub works. But that is worse: xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1280, current 1920 x 1280, maximum 1920 x 1280 default connected 1920x1280+0+0 0mm x 0mm 1920x1280 78.00*
