Help with radeon-git, X700 and dual head needed...

[signor_rossi]

I hope it is allowed to link to another forum, but some guy has these problems and couldn't find a solution yet.

If this is not o.k. notify me and I will edit the post asap!

Any ideas?
Is there something special with ATI Mobility X700?

[agd5f]

Does:
Option "R4xxATOM" "TRUE"
Help?

Option "R4xxATOM" "TRUE"
Help?

That was the solution! I'm very impressed and happy.
The picture is there, no black screen on LVDS. Still a clone, but I will try how to handle this.

Btw. What does this option mean?

Make sure you are using 6.12.2 or newer. There was a bug in the crtc routing in the r4xx atom code.

Btw. What does this option mean?

It uses atombios for modesetting on r4xx hardware.

[mmre]

Ok, I'm using 6.12.2.99.
If the bug should be fixed in this version, that isn't so.

[agd5f]

It was fixed prior to 6.12.2, so it is fixed in the version you are using.

What's the problem you are seeing?

[mmre]

What I want:
VGA-0 1680x1050
LVDS 1280x800

VGA-0 should be left of LVDS

I tried a lot with xrandr, --left-of --pos..., but sometimes the positioning is wrong or VGA-0 shows: Out of range.

It would be nice if somebody can help me.

[agd5f]

make sure you have a big enough frame buffer reserved for the size of the desktop you want. You may need to add a virtual line to your config.

[mmre]

How do I reserve Framebuffer? Virtual line is activated. It seems to be a problem that both screens has a different resolution. I just can activate the small resolution at the big screen (but xrandr -q tell me that I use 1680x1050...)
