QNX 6.6 x86 VM and Screen Graphics Subsystem   
I have downloaded and set up the QNX 6.6 x86 VM and got it booted to the shell prompt. However, like others, I too 
notice that there is no "UI" (Photon), like in 6.5. The release notes point out that Photon has been replaced by Screen.


I am trying to get Screen to work on my x86 VM.

I have read portions of the "Screen Graphics Subsystem Developers Guide", Chapter 10, "Apply your Screen configuration".
 The graphics.conf file is the one that comes along with the VM image.

I have set GRAPHICS_ROOT to /usr/lib/graphics/vmware
I have set LD_LIBRARY_PATH to /usr/lib:/lib:/lib/dll

I then start the Screen from the command line as /sbin/screen.

I see only a blank screen. i don't see any UI.

Is the QNX 6.6 x86 VM supposed to support the Screens application? How do I get the "UI" on the QNX x86 VM?

thanks,
Michael Tasche

io-display has been replaced by screen.

Could be ok. Screen is only the base for different grafics-frameworks, like qt, opengl, ...

Yes.

A standard preconfigured graphical QNX UI does not exist for 6.6., as far as I know.
There are many other things, which are discontinued in 6.6. Thanks to Blackberry.
Do you need something special from 6.6?
I try to solve my problems with 6.5. as long as possible.

Re: QNX 6.6 x86 VM and Screen Graphics Subsystem   
I think the first step would be to try to run ³sw-vsync² or ³gles2-gears²
and confirm that the display is working OK. Next you could decide on a
graphics framework like QT or Crank Storyboard, etc. depending on your
specific use case.

Re: QNX 6.6 x86 VM and Screen Graphics Subsystem   
Here is what I did. I ssh'd into the VM and started screen, could verify it via pidin. I then started the gles2-gears 
application.

On the VMPlayer, I t took the console of the VM hoping to see the output of gles2-gears. However, I see nothing - same 
black screen. It seems there is something in there, because the mouse pointer changes when I hover over the VMPlayer 
console window, but nothing is visible.

I am using the stock graphics.conf file that comes with the x86 VM. Do I need to modify that to make this work?

Hi, 

Did you manage to get this resolved? I'm also getting the same error, where after running "screen", the screen turns 
black with just the mouse pointer.

Thanks.

Re: QNX 6.6 x86 VM and Screen Graphics Subsystem   
Ensure that you have the two Screen for QNX 6.6.0 updates applied (along with the other required updates outlines in the
 installation instructions).  Additionally you can refer to the x86 BSP for 6.6.0 posted on the BSP site for an example 
build file to make sure you have set the env variables and started the various services correctly.
