English Multimedia

Suse 13.1, HDMI always shows a blank desktop image regardless of the video on the monitor. Raedon HD 3200 graphics, device RS780M/RS780MN. Hardware is good, works OK in Windows 8.

What driver??

Is this what you want?

You might want to try the propritary ATI driver you are using the open source Radeon driver. May make a difference

Does the proprietary driver support the RS780M [Mobility Radeon HD 3200] ? I had a laptop with such hardware (I gave it away a year ago) and my recollection a year ago was that hardware was designated as legacy and no longer supported by AMD. If that the case, installing the fglrx driver may make this worse.

No.
The fglrx driver only supports HD 5000 (and Mobility Radeon HD 5000) and up.

I have no idea about the HDMI issue though.

This driver has:

1: Limited the resolution to one choice, 1024 x 768, which is unacceptable,
2: Made my preferred player, mplayer, non-functional, and
3: completely killed the HDMI output, shows as “No Signal” on the TV.

How do I get back to where I was?

You are not using that driver as it cannot even be loaded. As I said, it doesn’t support your card.
Most likely you use fbdev or vesa now, because fglrx would prevent radeon from being loaded either.

How do I get back to where I was?

Uninstall the fglrx driver again.
If you used that 1-click install button, just enter YaST->Software Management, type “fglrx” into the search field and press enter.
Then remove that shown package.

After a reboot everything should be the same as before.

SUSE wouldn’t boot after the changes. I re-installed SUSE. Now boots OH but HDMI problem persists. Still works OK in Windows.

10

Maybe this would help?
https://wiki.archlinux.org/index.php/ATI#HDMI_audio

I.e. add “radeon.audio=1” to the “Optional Kernel Parameter” line in YaST->System->Boot Loader->Boot Loader Options. But I’m not sure if this is still needed with kernel 3.11 or not.

Is there any possibility that after the PC has been booted, you can plug in the HDMI connection (with HDMI device powered/configured best possible), and then immediately type in a terminal


xrandr

and advise as to what output you get ?

Also, after having typed the above, copy the file /var/log/Xorg.0.log to http://susepaste.org/.

And also, in addition to /var/log/Xorg.0.log, copy the most recent /var/log/messages text (ie preferably the ‘messages’ ~50 lines or less associated with the HDMI device) to a separate http://susepaste.org/.

and then provide us the link to the suse past posts.

Hopefully that will provide information as to why this is not working for you.

You may be able to adjust the resolution in /etc/X11/xor.conf or the screen file in the xorg.confd directory

I had to for my current monitor since it does not talk to the computer to tell its capabilities.

Trick is to make a modeline for the res you want to use in the xorg.conf file. There are on line pages that compute the modeline for you also there is a CL utility (gtf)

This is what I’m currently using. Note need to be adjusted for your chip set and the res you need
