[SOLVED] Multi-Display setup in Linux

[lukasz.ruminski]

Hello,

 

I'm trying to benchmark valley running a 12 screen setup with our linux machine.

 

I've got 3 displays (one for each video card), each display is 7680x1080 ( spanning 4 1920x1080 screens )

for a total resolution of 7680x4320. Is it possible to configure Unigine to render to 3 displays?

 

Currently i can only get it to render a single display (7680x1080) but not all three.

 

Thanks,

Lukasz.

are you running twinview or xinerama. or are you running a separate xserver for each screen.

If the latter you might find it a bit tricky

With xinerama i get less than 1fps -- it doesn't seem to be hardware accelerated.

Without xinerama i get a decent 60+ fps on each X display. There must be some threaded rendering mode that would allow synchronized rendering to each xDisplay. Otherwise the wall mode isn't really true wall support (at least not within linux)

Hi,

 

What GPUs are you currently using?

[lukasz.ruminski]

i've got 3 ati 9690's, each setup as a separate X display.

Hi,

 

Unfortunately, you need to create your own AppWall configuration which will works correctly with your 12 screens setup. Out of the box AppWall plugin supports up to the six seprate screens in following configurations:

1. 2 monitors in a column (1×2)
2. 2 monitors in a row (2×1)
3. 3 monitors in a row (3×1)
4. 4 monitors in a row (4×1)
5. 5 monitors in a row (5×1)
6. 4 monitors (2×2)
7. 6 monitors (3×2)

You can check and modify core/scripts/system/wall.h file to add support of your 1x3 display configuration (or 4x3 with 12 separate screens).

 

After that you can launch engine with AppWall plugin and specify number of monitors in a column and in a row (-width / -height parameters).

 

Thanks!
