Can you try booting with radeon.new_pll=0 added to your kernel command
line (not at the same time as the radeon.modeset=0 request above) to see
if it fixes the issue also?
** Description changed:
Binary package hint: xorg
As described, the external display shows massive horizontal offsetti
I think it's likely that the modeline is just slightly off.
Boot without KMS (radeon.modeset=0) and capture an Xorg.0.log, then boot
with KMS on. We should compare the calculated modelines shown in each
log for the activated resolution to see if there's any differences.
** Changed in: xserver-xo

Thanks, this sounds sort of like a modesetting issue and probably should
go upstream. That would explain why the behavior varies on different
resolutions. Does it work properly if you boot with the
radeon.modeset=0 grub option?
