I notice that this system is using the radeon driver but does not have the Radeon firmware installed. On older hardware the firmware is only needed for 3D acceleration, but I suspect that other functions also depend on it now. (And I've also seen some weird display glitches on a fairly old Mac when the firmware was not installed.) So, try installing firmware-linux-nonfree, if it doesn't offend your sensibilities.
