SUMMARY: Solaris 2.5 login bug??

From: Kohler R. P. (

Original posting : see below.

Solution: Evidently, Solaris 2.5 doesn't attach the graphics drivers
prior to 1st login. Thus just after a reboot, the drivers will not be
loaded into memory, which caused our login scripts to break.

We use the command "prtconf" to find all graphics cards on a system, then
start up openwindows with the correct flags containing all the graphics
/dev/cgxxxxx names...

Note the output of "prtconf" just after reboot.

/usr/sbin/prtconf | grep cg
            cgsix, instance #0 (driver not attached)

We try to start 2 heads, thus we were passing "cgsix0 (driver" as valid /dev
entries, which obviously failed on the 2nd device. cgsix0 would get loaded
prior to the system bombing, thus 2nd login attempt would produce the Sol_2.4
and Sol_2.3 results...

/usr/sbin/prtconf | grep cg
            cgsix, instance #0

This would then work fine...

I fixed my code to merely cut everything on the line after "(".

NOW: To get a list of graphics card /dev entries to use:

set FBLIST = `/usr/sbin/prtconf | /usr/bin/grep '\<cg' | /usr/bin/cut -d"(" -f1 | /usr/bin/sed -e 's/, instance #//'| tail -2`

Thanks to for his reponse to login normally,
and trace each step to see what was breaking.
