On http://www.x.org/wiki/radeonhd#head-d2ffccb02dd625f846dd8197bad71ee38109b876it it is stated to always report when HPD is needed to use a monitor. My Monitor (Samsung LE26B350 26 inch TV with HDMI) does work well, when switched before the start of X11. If it is switched on later I need to restart gdm and kill some failsafe X11 processes. By using HPD off it does work. I have Ubuntu 8.10 running on a system using amd g780 as chipset with the monitor attached to the onboard hdmi. I can send more logs if needed.

Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component. Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Closing due to lack of response. Please reopen and move to the Driver/Radeon component if this issue persists with xf86-video-ati
