I heard RTP has a good support for ATI video cards. I have one of them. System works fine, but I
have a question.

I wonder offscreen allocation is not supported by my video? Or, is it driver’s issue? How bad is
it?

Older video cards did not have a lot of memory. The
driver does support offscreen memory and so should your card
as long as memory is available. How much memory does your
card have? How much offscreen memory are you trying to allocate?
Do you have other applications running that may be using offscreen
memory? Have you tried running at a lower color depth (16 instead
of 32)

I guess 2mb , I’m not sure
How much offscreen memory are you trying to allocate?
There is sloginfo output at once Photon started. I don’t try anything yet.
Do you have other applications running that may be using offscreen
memory? Have you tried running at a lower color depth (16 instead
of 32)
I’ll do experiments. I’ve looked through VESA modes list for my card in order to determine free
memory. I was under assumption that memory is enough for 2 buffer 800x600x16. (1 meg for buffer) Is
not it?

And I have yet another question (Erick, probably it’s for another people). The graphics settings
are applied for Photon for all users, is it right? Okay, and ANY user HAVE ABILITY to change these
settings, is not it? Was there any security analysis in Photon development? Well,
Is there any recommended way to disable changing of graphics subsystem settings for ordinary users
in QNXRTP 6.1A? I wish to allow it for root user ONLY.
Yup, just change the permissions on the file so that noone other than root
can read or write to the /etc/system/config/graphics-modes and graphics-traplist
files and you should be able to do it then.
Thank you very much, Erick. You open my eyes, those were really memory problems >

Please be so kind and tell me what exactly I should do . I’m newbie and I’m still out of luck.
Here is the some of my research results:
/etc/system/config/graphics-traplist is created by enum-devices (I think) during boot up. It has
permissions “-rw-rw-rw-”. Changing the permissions to “-rw-r–r–” or “-rw-------” has no effect
(of course, changes will lost after reboot - no problem to change permissions in startup script (I
guess), but it does not make the trick). I changed permissions as root, then login as Eduard on
other console, type “ph” and freely change graphics settings.
/etc/system/config/graphics-modes has permissions “-rw-r–r–”. Photon is no longer accessible
for users except root if I change the permissions to “-rw-------”:
$ ph
Running crttrap, please wait…
/usr/photon/bin/devgt-iographics -dldevg-rage.so -I0 -d0x1002,0x4755
/usr/photon/bin/devgt-iographics -dldevg-vesabios.so -I0 -d0x1002,0x4755
crttrap: wrote config file as /etc/system/config/graphics-modes
