Hi,

I use Slackware64 14.1 that I just upgrated from 14.0. Then, I upgraded the nvidia driver, before launching X. Apparently, all went well. Then, using KDM, I tried to connect to MATE as usual.

However, only the desktop background appeared, while I was greeted by a dialogue box saying "No system tray detected on this system, unable to start exiting" and get stuck here.

Then, I tried a KDE session which works fine, without issues.

What is the problem? I use MATE from the slackbuild along with KDM and it workers without problems till now.

I found that this error is linked to hplip, for managing printing. I wasn't sure that I had it installed but then I saw it on the desktop pannel of my KDE session. The issue is the same as here http://askubuntu.com/questions/10182...t117723_101828 but since I use slackware, I wonder how can I fix it.

Hello,

You can try :

1. to remove the directory ~/.hplip as stated in this post from this thread

Code:

rm -rf ~/.hplip

2. To mimic the workaround given in the link you have posted, you can try to add a delay in/etc/xdg/autostart/hplip-systray.desktop. Edit this file, and change the line:

Code:

Exec=hp-systray -x

by :

Code:

Exec=/usr/bin/sleep 45 && hp-systray -x

Note:There's strictly no guarantee this will work.

3. if you don't need hplip, you can :

a. remove it :

Code:

$ removepkg hplip

b. disable it. For that, you need to rename the file /etc/xdg/autostart/hplip-systray.desktop, for instance :

Code:

$ mv /etc/xdg/autostart/hplip-systray.desktop /etc/xdg/autostart/hplip-systray.desktop.disabled

I removed hplib, whilst all the directories having been deleted by removepkg, I didn't have to do it.

However, after reboot, whilst the annoying dialogue box has disappeared, only the desktop background of MATE appears...

Which version of mate do you use?

Unfortunately, I don't know how to check the version...

Fine, it is mate-desktop-1.6.1-x86_64-1_msb

Since you upgrade to 14.1, i would recommend you to upgrade to 1.8
Other solution if you want to keep using 1.6 is to rebuild mate from source so that it links to the correct libraries in your system

Then, I will install 1.8 from the slackbuild, but will this upgrade the old version (eliminating it) or keep it and cause conflict?

EDIT: I found upgrade.txt.

From KDE, I tried to run caja and with the following reply:

caja: error while loading shared libraries: libxcb-util.so.0: cannot open shared object file: No such file or directory


Strangely, I miss some libraries, which may be the reason of the inability of MATE to work. I may use slackpkg reinstall slackware64 but I'm afraid this command will eliminate the multilib system in place.

Else, can I see all the missing libraries?

Don't forget to remove some packages mentioned on upgrade.txt

Just to be sure, did you upgrade to 14.1 or current?
When you upgrade to a newer version of Slackware, many libraries, including X-related gets upgraded as well and since MATE is built against a certain version of Slackware (14.0 in your case), some will not work properly under new version of Slackware (14.1) since it still linked to the old one. The solution will be upgrade your MATE or rebuilt MATE as i mentioned before

I have dealt with this HPLIP system tray message on a much simpler level when I'm using a desktop/window manager that lacks "system tray" capability.

It has nothing to do with functionality, only with eye-candy. I ignore it and it goes away.

Finally, I upgraded MATE and now everything works fine.
