Description Johannes Schmid 2009-01-19 01:46:26 UTC
On my setup:
- Asus D2 X EAH3650 SIL Magic/Htdp Radeon card
- a ViewSonic monitor (connected to DVI-0)
- a LG Monitor (connected to DVI-1 with DVI-to-HDMI adapter)

xrandr -q has the following output when both are connected:

For radeonHD the lastest available driver from https://launchpad.net/~tormodvolden/+archive is used together with stock Ubuntu Intrepid X-Server.

Windows has some issues with detected the LG, too, though it works fine on boot-up (e.g. before any graphical interface is started...)
Comment 1 Jeremy Huddleston Sequoia 2011-10-16 15:59:50 UTC
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.
Comment 2 Johannes Schmid 2011-10-16 18:23:01 UTC
Wow, this one is old...

Actually it is working with newer version of the driver, at least the version from Fedora 15 that I use currently. I am fine with closing it - thanks for all your work.
