nxagent fails to run with "Could not open default font 'fixed'" #84

Open sunweaver opened 8 years ago

From X2Go Bug #884: http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=884

Yes, I am talking about Gentoo specific packaging issue. I have filed

https://bugs.gentoo.org/show_bug.cgi?id=559370

to track it down. As I mentioned, the specific files being talked
about are the font files in /usr/share/fonts/misc
(/usr/share/fonts/X11/misc on Ubuntu) which are character encodings
specific e.g. 9x15-ISO8859-*.pcf.gz. nxagent can not load a fixed
size font '9x15' without the presence of these files. It looks like
these are abandoned by modern X code because both Xorg and Xvnc work
fine without these files.

-devsk

Thanks for explaining the above. However, I think that we should get
this issue also solved upstream as most systems work on UTF-8 basis
and the more local encodings are rather historical than
current-state-of-the-art.

Let's leave this bug open and address it for 3.6.x of nx-libs instead
of dealing with it as a Gentoo specific bug.

The real work to fix this is backporting this X.org patch: https://cgit.freedesktop.org/xorg/xserver/commit/?id=49b93df8a3002db7196aa3fc1fd8dca1c12a55d6

Reopening, because this doesn't seem to be fixed.

Seen with nightly nx-libs versions on a Devuan Jessie system for some odd reason.

This is odd, indeed. The code for that error message is gone afair. Please do some more investigation if possible.

Thanks, Mike

There are still several references to the "fixed" font in the code, e.g. as the default font that is used for font replacement or as the default font that is compiled in:

/nx-X11/programs/Xserver/include/site.h:#define COMPILEDDEFAULTFONT    "fixed"

Also the basic error message is still there:

./nx-X11/programs/Xserver/dix/main.c:       FatalError("could not open default font '%s'", defaultTextFont);
Bdot42 commented 1 year ago

The 'Could not open default font 'fixed'' still occurs on OpenSuse, x2goserver-x2goagent: 3.5.99.24 (from x2goserver-x2goagent-4.1.0.7-0.0x2go1.0.git20230823.1996.heuler.x86_64 = latest nightly build). Is there anything I can do to analyze that further? Is there a workaround to get the server to run?

I too had a similar problem. I was trying to connect to Debian with Manjaro. As it turned out (thanks to stackoverflow!) - remote connection takes local fonts. So I just had to install some packages in Manjaro to get the fonts I needed and update the cache (fc-cache).

uli42 commented 10 months ago

It really should not happen anymore. 3.5.99.24 is very old, please update to 3.5.99.26 or .27

My nxagent version is 3.5.99.26-5+deb12u1. I connected to the server via SSH, ran nxagent :55 and got the error "Could not open default font 'fixed'" until I found out that the problem was a lack of client-side fonts and installed additional packages. After that, both the nxagent command and the x2goclient call started working for me.

uli42 commented 10 months ago

Was referring to the latest comment mention 3.5.99.24. However, you are right, the corresponding code is still existing in recent builds. Hmm.

And it is also still part of the upstream Xserver code - despite various people mentioning the fixed font is not required for current Xservers. Must do some research here, it seems...

See e.g. https://www.x.org/wiki/FAQErrorMessages/#index1h2

uli42 commented 10 months ago

On my Debian 12 system I cannot provoke the "could not open default font 'fixed'" even by removing all fonts. You can verify this by running nxagent -ac :55 and then DISPLAY:55 xlsfonts - you will still see the fixed fonts because they are built into libXfont.

So maybe on your system there's something wrong with libXfont?

MAH69IK commented 10 months ago

Debian 12 - is my server. I needed to install fonts on the client, Manjaro, which would solve the problem. I used the command pacman -S xorg-fonts-100dpi xorg-fonts-75dpi xorg-fonts-cyrillic xorg-fonts-type1 xorg-fonts-misc. I think xorg-fonts-misc was sufficient. I had libxfont2 installed, it was fine. 2.0.6 on the client and on the server.

EDIT: This seems to work: $ nxagent -ac -fn lucidasanstypewriter-10 -fc lucidasans-24 :55

but not this: $ nxagent -ac -fn fixed -fc cursor :55

While this workaround gets it to open and run, I don't know how to make x2go call those kwargs so I will have to file this under interesting but not immediately helpful.
