[GRASS-user] Tcl/Tk gui and nviz errors

GRASS GRASS user

Hi

I am getting errors (after updating and re-compiling) trying to start
the Tcl/Tk gui and nviz, as shown below. I am using GRASS 6.5 r38466
on ubuntu 9.04. Any ideas on what I have done wrong?

Thanks

Craig

That's strange. It's there for ages and I don't see any changes on
TCL/Tk side about supported color names.

Can You provide information about Your TCL and Tk versions?

Here it works... could you try:

?

Markus, You seem to be right. Only problem - that thread is missing
solution: http://lists.centos.org/pipermail/centos/2008-November/067397.html

Citing here for history:

check your /etc/X11/xorg.conf on the differents machines.
-> RgbPath "/usr/share/X11/rgb"

It was different between the two machines...

On the machine that worked the RgbPath was not specified.
It was specified on the machine that did not work...
I commented it out and rebooted and it started working.

Thanks,

Jerry

This seems to be a bug with newer ubuntu versions because they no
longer ship with /etc/X11/rgb.txt. See the following bug report for
details:
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/300935

I copied /usr/share/pixmap/rgb.txt to /etc/X11/ and restarted X. Now
Tcl/Tk gui works, but there are still problems with nviz:

nviz -q

Error in startup script: Togl: couldn't get visual
    while executing
"togl $Nv_(TOP).canvas -rgba true -double true -depth true"
    (procedure "Nv_makeGUI" line 56)
    invoked from within
"Nv_makeGUI $Nv_(AREA)"
    (file "/usr/local/src/grass6_devel/dist.i686-pc-linux-gnu/etc/nviz2.2/scripts/nviz2.2_script"
line 1052)

Thanks for the tips, I'm making progress. Any more ideas about the
remaining nviz error?

Solved by removing the package libgl1-mesa-dri. You can't do direct
rendering on a remote display!

Note to self: First check if glxgears works before blaming GRASS :slight_smile:
