Cannot display photon window from QNX   
I'm running Neutrino 6.4.0 on a Virtual machine, and having problems getting the Photon graphical interface to load.

When I run "ph" at the QNX command line, I get the following error:

# ph
Unable to start graphics driver(s)


The following is some useful info I retrieved based on comments in another post. Unfortunately, that post didn't 
complete and no solution was listed, so I'm hoping some can help me out here.

Re: Cannot display photon window from QNX   
It looks like /etc/system/config/display.conf contains:
pixel_format=argb8888 
for the VMWare driver. The driver can't find this mode.

Try changing windows to 32 bit, or try changing pixel_format to a format that matches your windows setup. I guess you 
will need to restart VMWare too.

Re: Cannot display photon window from QNX   
Thanks for the reply.

I've verified within my Display properties in Windows that I'm setup for 32bit, then restarted Vmware server processes 
on the Linux host system. The problem unfortunately still exists, and Photon cannot start. Is there any issue between 
running Photon on a Windows desktop, when VMware Server is running on a Linux host machine?

I've included a copy of my display.conf file from the virtual QNX host.

Re: Cannot display photon window from QNX   
I guess in your case you need to make sure that your linux box runs in 32bit mode. If this doesn't work try different 
pixel_format: 
argb1555, rgb565, rgb888 or argb8888.

Re: Cannot display photon window from QNX   
Hi Misha,

Thanks for your help.

I needed to ensure the Display settings on the Linux server, matched those in the display.conf file on the VM, in my 
case 1024 x 768 and 60 Hz.

It was then a matter of trial and error with the four pixel format options. Each time I had to apply the changes to 
display.conf, shutdown the VM and restart VMware on the server. After doing this with the pixel format set to rgb565, 
the photon display was available.

Thanks again :)
Dan
