missing Font?

[reggler]

I can't even pull ip Portal in Muon and the installed files for oxygen-gtk are:
/usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/engines/liboxygen-gtk.so
/usr/share/doc/gtk2-engines-oxygen/README.gz
/usr/share/doc/gtk2-engines-oxygen/changelog.Debian.gz
/usr/share/doc/gtk2-engines-oxygen/copyright

It seems odd that you can't find Portal in Muon. I have no explanation...

Well when I enter Portal, I get a whole bunch of entries but none called "Portal"

Filter by 'Status' and then further with 'Installed' only. You can see this in the screenshot I posted earlier.

Yes, it ran just fine before I updated to Kubuntu 12.04 (on 11.10)

Do you have access to another machine, one where the application in question operates normally? If so, one technique to find out how the two installations differ is to use the tool lsof. If the name of the running program is portal, then you can show all files that the program has opened with the command

lsof | grep portal

lsof has many options; a quick study of the man page would be useful. Compare the output of this command on the system that runs properly to the output of this command on the system that isn't running properly. Are there any differences?

Oh, just thought of something else...occasionally I've seen instances where the Gtk theme files don't load because of improper environment variables or hidden directories in your home folder. What's the output of

env | grep -i gtk
ll .gtk*

[reggler]

I unfortunately have no other Linux machine where this software is working correctly at this time...
Since I'm running this program under root(due to required USB access), I also will need to check the environment variables of root, right:

root@desktop-reg:~# env | grep -i gtk
root@desktop-reg:~# ll .gtk*
-rw-r--r-- 1 reg reg 82 May  1 16:54 .gtkrc-2.0-kde4
root@desktop-reg:~#

And as user I get this:

reg@desktop-reg:~$ env | grep -i gtk
GTK2_RC_FILES=/etc/gtk-2.0/gtkrc:/home/reg/.gtkrc-2.0:/home/reg/.gtkrc-2.0-kde4:/home/reg/.kde/share/config/gtkrc-2.0
GTK_RC_FILES=/etc/gtk/gtkrc:/home/reg/.gtkrc:/home/reg/.kde/share/config/gtkrc
reg@desktop-reg:~$ ll .gtk*
-rw-r--r-- 1 reg reg 82 May  1 16:54 .gtkrc-2.0-kde4
reg@desktop-reg:~$

[SteveRiley]

Well, all that looks fine. At this point, I'm not sure what else to suggest...

[bra|10n]

Out of curiosity I ran the following and highlighted the difference to the OP's,

root@Aspire-5750-Precise:~# env | grep -i gtk
root@Aspire-5750-Precise:~# ll .gtk*
-rw-r--r-- 1 [COLOR="#FF0000"]root root[/COLOR] 292 May 11 19:34 .gtkrc-2.0-kde4
root@Aspire-5750-Precise:~#

[SteveRiley]

Whoa, wait...that's curious. While I'm not sure that's the root of the problem, it's worth fixing.

Reggler, please:

sudo chown root:root /root/.gtkrc-2.0-kde4

Are there any other files in /root that are owned by someone other than "root"?

[bra|10n]

Would this not have broken gtk linking?

[SteveRiley]

I can't say for sure, as I don't have a .gtkrc file in /root at all. But this is on my X1, with KDE packages installed by hand. A normal Kubuntu install, I suspect, would appear like yours -- I'm not near my T520 to verify at the moment.

It is odd that a file in regger's /root is owned by a non-root account...

[bra|10n]

I thought this 'scenario' was probably a workaround of sorts prior to the introduction of gtk3 and the subsequent changes it brought.
And on that assumption figured it may now not work on 12.04...

[bra|10n]

Probably a pointless exercise, but what happens if you run,

gksudo portal

[SteveRiley]

gksudo is not typically installed in Kubuntu...

[reggler]

Whoa, wait...that's curious. While I'm not sure that's the root of the problem, it's worth fixing.

Reggler, please:

sudo chown root:root /root/.gtkrc-2.0-kde4

Are there any other files in /root that are owned by someone other than "root"?

Well, first see this:

root@SemiosDesktop-reg:~# pwd
/home/reg
root@SemiosDesktop-reg:~# ll .gtk*
-rw-r--r-- 1 reg reg 82 May  1 16:54 .gtkrc-2.0-kde4
root@SemiosDesktop-reg:~# cd /root
root@SemiosDesktop-reg:/root# ll .gtk*
ls: cannot access .gtk*: No such file or directory
root@SemiosDesktop-reg:/root#

So I didn't do change the owner for the files in "~" which even as root is /home/reg
