Created attachment 24979 [details] This tarball contains four different files. The radeonhd driver for my graphic card (VGA compatible controller: ATI Technologies Inc Device 9596, Subsystem: Hightech Information System Ltd. Device 0028, which I think has chipset RV635) seems unable to detect my dual monitor setup. This problem was present with Intrepid and is still present with the new radeonhd 1.2.5 driver (downloaded with git on 20090417) on Jaunty, so I decided to file a bug report. Long story short, with the radeon driver everything seems to be fine, but the radeonhd driver seems to believe that only one monitor is connected. I am attaching the Xorg.0.log files and the output for 'xrandr -q' for both configurations, that is, with radeon and with radeonhd. I hope this should be enough to pin down the problem, but feel free to ask me for more information. On a side note, the fglrx driver freezes the X server, so I uninstalled it on my system. The version of the X server I am using is 1.6.0 but I guess all of this is irrelevant since same problem happened equally with Intrepid and Jaunty, both with driver 1.2.4 and driver 1.2.5. Let me know if there is anything I can do to better describe the problem.
I just checked first 5 lines of radeonhd log: (EE) RADEONHD(0): The fglrx kernel module is loaded. This can have obvious or subtle side effects. See radeonhd(4) for details. Reproduce with removed fglrx and after full reboot (even better with powering off for being 100% sure) please.
Created attachment 25000 [details] This tarball contains four different files. Here I collected the logs again, this time with the "xrandr --verbose" option. Whatever the problem is, it has been there for quite a while, since I had it with Ubuntu Intrepid as well since I bought this graphic card. By the way, why is the interface for bugs.freedesktop.org so badly designed? It really turns you down when you want to file a report, especially if it is the first time.
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
