I suspect I need to load a HDMI driver for opensuse 11.2 64 bit.
What driver do I need to install ?
Thanks Glenn

ATI Radeon HD 3200 Graphics uses the RS780 chipset.
... do you get a picture off this card with vga output?
... have you tried another monitor on hdmi?
... will the monitor handle the resolution/frequency combination?
... have you checked the xorg logs?

You do not normally need a special driver for a monitor, it is your graphics cards job to cope with this. You do need to be able to detect the modes to use though, and benq monitors are notorious for not supplying them.

The graphics cgard driver you want is called "Radeon".

HDMI audio is considered "work in progress" eg. it does not go. But the video stuff seems to have been finished. The driver is in the kernel already, so you may just need to check it is being used.

OpenSUSE may be using radeonHD - in which case kernel modesetting will give you a black screen. Make sure you are using Radeon. iirc: openSUSE still uses /etc/X11/xorg.conf, so go look.

... lots of people seem to use fglrx (from the repo is preferable to installing off the ati site) for this card.

You are not the only one:

Re:

This is on a laptop with hdmi socket for external monitor, no vga output socket.

> have you tried another monitor on hdmi?
Cant try another hdmi monitor , have not got another one to try.
I did try the monoiror on another older laptop with a vga output which did work - so the monitor does work.

> will the monitor handle the resolution/frequency combination?
hwinfo detects the following -
Should work with the at least with the resolution/frequency standard ones.
Available ones
