I try to install QNX. I think when the install tries to switch to graphical
mode, the system freezes, the screen goes black and twice a second there is
a short hard disk access. When I re-boot and don’t start Photon (F1 option),
I get a command prompt and can all non-graphical things seem fine.
I suspect my graphics card. This is a Matrox Millennium G200 with a digital
flat panel head only (special production for IBM digital flat panel
monitor). In this mode this card only supports vesa compatibility for
resolutions up to 800x600. So I think I have to tell the system to use a
resolution of 800x600. How do I do this (during install, or otherwise as a
boot option or from the command prompt)?
thanks in advance,
Wim
Hi,
In your /etc/system/config/graphics-modes file there is a listing of all the
supported modes (resolutions and colours). Copy the line with your preferred mode
to the top of the file. Then start photon.

Hi,
In your /etc/system/config/graphics-modes file there is a listing of all
the
supported modes (resolutions and colours). Copy the line with your
preferred mode
to the top of the file. Then start photon.
Thanks very much.
I tried and the freezing makes a different sound now, but the screen still
gets black and the system freezes like before.
I discovered that when booting from the demo disk, I can set the video to:
driver = flat, resolution = 800x600x8. This would be fine for me. In that
boot there was no graphics-modes file, though, so I could not copy that
setting to my installed file. How can I set the settings mentioned above for
the installation? Would the ‘flat’ driver be installed in my case? (if not:
how can I do that without Photon running?)
thanks,
Wim
Hi Wim,
Could yoy please run the graphics script located here:
www.geocities.com/erickmuis/files/hardware_scripts
Save it to your QNX partition, then login as the root user. Once logged in
‘chmod +x grafxscript.rtp’ to make it executable.
Then simply run the script (still as root).
…/grafxscript.rtp
Then send us the output file.
Thanks!
Erick.
