NX (www.nomachine) Errors after upgrade to 10.2

linux_junky · 12-15-2006, 03:12 PM

Hi,

Last Friday, I upgraded to openSUSE 10.2--basically everything is going fine--have been using that distro since 9.3.

What's bugging me is that the Nomachine NX client is not working anymore--have not been able to figure out what is wrong.

Background: I have upgraded the nxclient, nxnode, and nxserver to the latest patch releases.

I get the following error when I test with my remote and localhost:

/***** log begins here

Any ideas?
Thanks in advance for your help.

I'm having a similar error here. I hope it isn't caused by the X.org 7.2 release openSUSE 10.2 ships..

And when I enable the syslogging I see the following lines in /var/log/messages:

Basically I'm logged out when I try to login.

I've managed to fix this problem

first check in $HOME/.nx/F-.... for a 'session' file. It's a log of the session. Mine ended with the error message:

Quote:

Fatal server error:
could not open default font 'fixed'

With the new X.org all fonts are in /usr/share/fonts. I've ran "fc-cache -fv" and "/sbin/conf.d/SuSEconfig.fonts" to update the fonts, and finally decided to move all remaining TFF fonts at /usr/X11R6/lib/X11/fonts to /usr/share/fonts, and change /usr/X11R6/lib/X11/fonts into a symlink that points to /usr/share/fonts. Ran fc-cache and SuSEconfig again, and now NX works

yapp,
Thank you so much for your reply and most of all SOLUTION!

Would you be able to break that down into a command line-by-line directive for me? Otherwise, I'll take the ball and run with it.

Again thanks and Happy Holidays to you!!

Well I would try the following:

- first see if there are any interesting files left in /usr/X11R6/lib/X11/fonts/ e.g. I still had some Windows truetype fonts there. Copy those to your new /usr/share/fonts directories.

- then:

Code:

fc-cache -fv
/sbin/conf.d/SuSEconfig.fonts

cd /usr/X11R6/lib/X11/
rm -Rf fonts/
ln -s /usr/share/fonts .

fc-cache -fv
/sbin/conf.d/SuSEconfig.fonts

But I recommend inspecting the session logs first and inspect the font folders before running the commands blindly.

Happy holidays to you too

linux_junky · 12-23-2006, 09:10 AM

This is the tail of what I see in the 'session' log for my last attempt--does this correspond with your issue--seems like the same thing? (thanks yapp!):

That did it yapp (wooo hooo!)
Thanks for the XMAS gift!
Best!

vakanderson · 12-29-2006, 12:58 PM

The solution worked for a clean install of openSuSE 10.2 also! Have a great New Year's celebration!

linux_junky · 12-29-2006, 01:36 PM

Great.
Yes I did another install of 10.2 and straight up it works with the above steps.
Happy New Year Folks!

Hi All,

After few dates of googling, I found the solution:

Removing package artwiz-cursor NX and all works OK

apt-get remove artwiz-cursor
