Re: Multiple X Sessions on OSR 6

It fails syntacticly if NO X-session is running at all, and
it also fails here for me if session 0 is running, with:

exec /usr/bin/startx -- :1

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

I get the same error if I just type 'startx -- :5'.

Yeah, and command line startx fails with me in various ways.

I'm happy with it, but I don't think OSR 6 is ready for Prime Time.

The display you fixed for me on my console I like (as user "bob").

However, after it's in place, other startx as user "root" work
sometimes, others not - most often failing with an error message
saying that /dev/mouse can't be opened.

Sometimes after I've started VNC, sometimes before.

Sometimes I can get two X sessions running, sometimes not (doing
a reboot between tests sometimes). When I get a second running,
I can't close it down within that second session - I have to go
to the first one and send an HUP to the login of the second one.

There's work to be done, but I'm a happy camper.

Apologies for such a late reply. I've been indisposed with the flu the
last week.

I haven't seen the specific problems you or JP mentioned. I have seen
two different problems though. I can usually start two X sessions
under two logins by the same user. If I attempt to start a third
session, X will start and give me the grey stippled background but no
window manager. After about four minutes the session times out and
dies with a "/usr/X11R6/bin/xinit: Server error." error. The
appropriate /usr/adm/Xorg.<x>.log file lists this error every 2
seconds:

AUDIT: Wed Oct 26 14:19:48 2005: 21614 X: client 1 rejected from local
host
AUDIT: Wed Oct 26 14:19:50 2005: 21614 X: client 1 rejected from local
host
AUDIT: Wed Oct 26 14:19:52 2005: 21614 X: client 1 rejected from local
host


The second problem I see is, upon issuing the startx command, it
changes video modes, then changes back and gives the errors:

_XSERVTransSCOOpenServer: failed to open /dev/spx
_XSERVTransOpen: transport open failed for sco/tenzing:5
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for sco

To be fair, I've never tried exercising X to this extent on pre-OSR6
systems so I can't say it wouldn't fail there as well. It does seem
there is still work to be done to get X up to speed on OSR6.

Happy to see you back, and in better health. How come you
didn't get you flu shot as I did?

Yeah. Sometimes it works, sometimes not. The same with VNC.

I've seen those AUDIT messages on the first X I've successfully
started, and then none on the second successfully started.

There's a lot to be learned. Maybe MP2 will fix a lot of it.

Thanks Bob. I just prefer to take my chances with the virus. This is
the first time in four years it hasn't worked in my favor.
