Problem:
Has anyone else upgraded a 4/110 with the Lego (GX) board from sun and had
the MIT sample server stop working? We are running SUN/OS 4.0.3., with patches
1-9 except the set in the middle that apply only to xman. We have some
Sparcstation-1's as well, and they work okay as other net-posters have claimed.
We were hoping our 4/110's would be identical now to the Sparcstation-1's
except slower processor speed.
What happens:
run xinit
(aliased to alias xinit 'xinit $HOME/.xinit; kbd_mode -a; clear_colormap')
the color of the foreground turns light orange (same as on Sparcstation).
the screen flashes for a micro-second, trying to initialize.
core is dumped
csh gets a million EOF's until it logs me out.
We have the same /dev entries on the Sparcstation-1's as the 4/110s, with a
cgthree0 entry and a cgsix0 entry.
Fix: (added 45 minutes after writing above paragraphs)
Since I wrote the above paragraphs, I tracked the problem down to line 506
in server/ddx/sun/sunCG4C.c, which is trying to enable the overlay plans.
I don't have the foggiest idea why it doesn't try to do this on the
Sparcstation-1 but if someone else wants to pursue it this is the place
to start. My hack fix is to remove the line that tries to do that:
#ifdef notdefPDA
/* Now set the enable plane for color */
if (index == 0) sunCG4CSwitch (&(pScreenInfo->screen[0]), 0);
#endif
Note that I had tried using xinit $HOME/.xinit -- -dev /dev/cgfour0 to
keep it from blasting the overlay planes but that didn't work. The server
dies saying "can't find any displays" and then logs me out.
I have to say, I find that the ability of the server to log me out by
screwing up my standard input is quite amazing.

I just got a new Sparcstation 1 on my desk (two days ago) which runs SUNOS 4.0.3 and I am told that the MIT X server is not going to run on it. Is this true? If that is the case, is there a fix? Mihran Tuceryan email: tuceryan@cpswh.cps.msu.edu

This happens because Xsun normally sets its standard input, output and error files into non-blocking mode. Normally, everything is reset upon exit, but if the server dies, things may not be cleaned up. The -debug option prevents setting non-blocking mode, but may cause some error messages to be lost (not flushed from the buffer)...

I don't think it much takes advantage of the board, perhaps that's what you heard? But it works, and it's even reasonably fast for general chores. Sunview, obviously tuned to the Lego, is much faster if you want to see what the machine is capable of. I assume you'll eventually get the X11/NeWS server from Sun and that will exploit the hardware. -- -Barry Shein Software Tool & Die, Purveyors to the Trade 1330 Beacon Street, Brookline, MA 02146, (617) 739-0202 Internet: bzs@skuld.std.com UUCP: encore!xylogics!skuld!bzs or uunet!skuld!bzs
