/dev/fb: Permission denied

I am experiencing this problem on SunOS 5.8:
------------------------------
calling xinit /usr/../../.xintrc -- /usr/openwin/bin/Xsun # .. is some directory - not important

/dev/fb: Permission denied
/dev/fb: Permission denied
Graphics Adapter device /dev/fb is of unknown type

Fatal server error:
InitOutput: Error loading module for /dev/fb

giving up.
xinit: Connection refused (errno 146): unable to connect to X server
xinit: No such process (errno 3): Server error.

This occurs only when I try to remote login in Exceed Hummingbird but not from the console. I need this processing to be allowed in a remote login session (through .login script.) I don't know why I get have a permission denied while login from the console works fine. Any ideas?

Thanks!!

After working on this issue, it appears that this is because the framebuffer (/dev/fb) is accessible only to /dev/console terminals (not to pseudo-terminals). If all I'm after is getting the image /dev/fb from the console, I execute ' fbgrab image.png' (on the console) and then converting the image.png - say to a jpeg or other type?

Thanks,
