RE: running xwinnmr remotely from Linux

Hi Jerry, Michael

I pulled this off an old archive (bumlist doesn't seem to have archive
still, right?). See below.

Basically, you need to run 8 bit color (I've done it this way for many
years by running a second x-server either from a shell or do Cntrl/Alt/F6
and then at the login prompt log in and then type in something like

startx -- :1 -bpp 8

which will start the second x server (but with 8 bits, not 32).
and then if you telnet or ssh into xwinnmr, do a ssh -X and then if the
DISPLAY environment variable is not set correctly on the other end, set it
manually but remember to do something like (depending on csh or sh/bash)

setenv DISPLAY mylinuxbox:1.0
or
DISPLAY=mylinuxbox:1.0
export DISPLAY

instead of :0.0.

and that should do it. you can go back and forth between the two x
servers by doing the Cntrl/Alt/F7, or Cntrl/Alt/F8, etc. documentation's
all out there at xfree86.org.

good luck,

Many thanks to all who responded to my request for info on switching
between the Linux Xserver between 8 bit colour (required by XwinNMR)
and 16 or 24 bit colour (desirable for most other things) It turns out that
you have to start two X servers: 8 bit and whatever other mode you might
want. The details of how to do this are definitely NOT clear in the docs
that came with my Red Hat 7 release, but ARE clearly explained in:

> http://www.bruker.de/analytic/nmr-dep/nmrsoftw/prodinfo/suite_linux/

or

> http://www.tsoft.com/~rnunlist/geek/geekpage.html
> http://www.tsoft.com/~rnunlist/geek/linuxnmr/

I then ran into some font problems. The Bruker buglist keyword
entry for "font" didn't list my problem, but their new site-wide search
engine will
show:

> http://www.bruker.de/analytic/nmr-dep/nmrsoftw/passwd/bugs/bug2478.htm

Thanks to Guenter Schmidt of Bruker for pointing this out to me. What
happens is that
when XwinNMR is searching for fonts it hits the new 16 bit "unicode" fonts
first, and these are
incompatible with XwinNMR. The fix is quite easy, and is detailed in
bug2478. Guenter
also pointed out that if you install unicode fonts on your SGI you will have
the same
problem.

Cheers, and thanks again!
