Hi Dmitri

Apologies. I've only just seen this mail - I setup a spam filter before
Xmas but it was too keen. I've just rescued this mail (and 3 others you
sent late 07) from my Junk folder. Grrr. Spam filter switched to OFF
now :)

Excellent thanks. What a relief!

Ok maybe I misinterpreted the comments. I thought that although the guy
said he wasn't explicitly using Xinerama (ie not positively enabled in
xorg.conf) that it was in fact still enabled because of the new RANDR
1.2 backend. Anyway I'm still not sure I can recreate that issue with
the gear I have here.

Yes. I'm currently running Ubuntu 7.04 (Feisty) which has Xorg server
1.2. To test with Xorg server 1.3 I've been using the bootable CD-ROM of
Ubuntu 7.10 (Gutsy).

I'm using a laptop with ATI RADEON X700. The laptop monitor is a
1440x900 LCD panel. It has an extra VGA out which I'm connecting to a
19" LCD external monitor.

In fact I have now been able to test cases 5 & 6 above.

Is your Solaris machine using what people refer to as the "old style
dual-head" configuration enabled with Option "DualHead" "true" in
xorg.conf? If so this is something I haven't been able to setup here.
But it's interesting you can't use FSEM as I would have presumed this
possible as long as Xinerama isn't actually in use.
