As mentioned in one of the postings above, it is easy to make Beryl
not using Xrandr, but Beryl crashes at a certain point. I had some
e-mail conversation with one of the engineers at nvidia and he is
pretty sure that the problem is related to some bugs in the X-server
concerning composite when xinerama is enabled. I guess this issue
won't be addressed unless one of the lead beryl-developers gets a
triple-head setup :-)

For now I'm using the old one. I'll try the X-Server one soon but it is still working very nicely, even without beryl

Hi,

Has this patch been submitted to the Xorg Development team for inclusion in Xorg 7.3? I think this would be an excellent enhancement to add, and would benefit a lot of people.

I am going to try very soon to patch 7.2 that comes with Ubuntu Feisty (I am now using 2x 7600GS cards, and Xinerama performance, redraw etc is very poor), hopefully it will help with my performance issues. Just got to work out what to do!

No.

Other than dragging windows amongst separate screens, Xinerama
scales actually pretty well, IMHO. The best solution for the redraw
issue would be to use a compositing WM, but unfortnuatly, Xinerama
doesn't yet work very well with the composite extension enabled.

Default Re: [PATCH] "faked" Xinerama information for a triple-head TwinView setup

Hi, since you seem to have experience with three large monitors
in a triple head setup, I'd like to ask some questions:

Is it possible to drag windows from any monitor to any monitor (one
big desktop)? I understood it is possible, though 'slow' while halfway
the monitors. That wouldn't be much of a problem imho, because normally
you don't leave windows halfway.

Is 3D acceleration and video support on all three heads?

Is it possible to play a 3D game like UT2004 over all three heads at
the same time?

Thanks,
Alaric

Yes, when Xinerama is enabled

I wouldn't call it "slow" - there is only a small, but recognizable
difference if windows are dragged within a twinview screen (no
redraw events) or amongst separate screens (annoying redraw events).

Yes, but you may like to adjust the FOV value, for details, check

Jaxxon,

Thanks very much for eliminating that nuisance.

I used your patch to apply it to -1.2.0 in debian/ubuntu. It works nice. I'm ecstatic.

Thanks again!
-Dieter

You are welcome :-)

I hope you used the new patch for the X-Server (see posting #10)
rather than the old one for libXinerama?

Right. I took the xserver-1.1.0 patch you provided and injected it manually into the 1.2.0 source. The -p1 patch is attached below.

I hope you don't mind, I submitted your patch to xorg. https://bugs.freedesktop.org/show_bug.cgi?id=10797

Exclamation Re: [PATCH] "faked" Xinerama information for a triple-head TwinView setup

First: Thanks everyone for working on that topic!

There are two small typos in the 1.2.0 patch:
FLAG_ZINERAMAINFO -> FLAG_XINERAMAINFO
"XineramaInfo -> "XineramaInfo",

I attached the corrected version

greetz,
Stefan

Default Re: [PATCH] "faked" Xinerama information for a triple-head TwinView setup

dieterh, could you possibly give me some pointers on how you patched the ubuntu xorg-server with this patch?

I've managed to successfully download, patch, and compile the new Xorg. However when I replace the old one, X no longer starts, it gives errors such as "unable to open /usr/local/var/log/Xorg.0.log" It seems to me that there is possibly something that needs to be edited/environment variables set at compile time. unfortunately I'm rather inexperienced when it comes to both X and debian. Any assistance would be greatly appreciated.

Default Re: [PATCH] "faked" Xinerama information for a triple-head TwinView setup

What steps can I take in Ubuntu Feisty (7.04) to implement/apply this fix?

I have posted on the Ubuntu forums hoping for help, but not sure how many are running triple head.

I am running 100.14.11 nvidia drivers and Xorg 7.2.0 (70200000).

I have x-configure in a somewhat working fashion but it rendering/redraws Firefox and Thunderbird very badly if I dare to drag a window in gnome. Performnce is so bad, i am considering going back to 2 head and dumping 3 head until this issue is resolved.

On a different note....in Vista, this performance/redraw problem is not prsent with triple head...even using the generic drivers....This is my work machine though so running Vista or even Ms windows of other flavors isn't an option...

Any direction greatly appreciated!
