OTRS does provide agent statistics to show on the dashboard. However, this settings is not active by default, so you’ll have to enable this feature in
Admin->SysConfig under the UseAgentElementInStats identifier first.
Go and search for it, using the upper left input field, as usual, then switch it on.
I’m not very much into suse linux, only lately for a couple of times. However, I want to share these settings to be injected on each and every new system for essential readabilty of some console screens. Problem is, for some apps, midnight commander and yast so far, the default color scheme settings provide that less contrast, see below, that you’re literally guessing pixels instead of just reading text.
As given in the referenced posts, only small tweaks are actually necessary to achieve much better results, I’ll give examples as well, so go for it, don’t postpone to the next and the next and the next… login 😉
LauncherFolders (http://unity-folders.exceptionfound.com , https://itsfoss.com/group-apps-unity-launcher-launcherfolders) is a great extension to the unity launcher, in being lightweight abd shipping a lot of bang when it only comes to set up containers organizing your apps. However, obviously the code has been crafted back in the Ubuntu 14.04 era, leaving open issues for installation on more modern Ubuntu releases.
First of all, the official ppa (ppa:asukhovatkin/unity-launcher-folders) will no longer register successfully for security reasons such that one has to ressort back to the original deb installation medium (http://unity-folders.exceptionfound.com/unity-launcher-folders_1.0.3_all.deb).
The next fixes, run the app from the console to see the error messages, are documented in (https://askubuntu.com/questions/934916/ubuntu-launcher-folder-not-working) and (https://ubuntuforums.org/showthread.php?t=2325175 , comment #5):
sudo apt install python-gobject python-pil
gksudo gedit /usr/lib/python2.7/dist-packages/unity_launcher_folders/generateIcon.py
#17 change: "import Image" -> "from PIL import Image"
Getting this far, the app itself comes up and is operable as expected. Pity is but, that the folder pane does not show up when clicking the generated launcher item (though it worked in the preview mode). The launcher item itself is nothing more than some .desktop file in (
~/.local/share/applications/Browser.desktop). On inspection, we have this exec entry:
Giving it another console output run reveals another missing python dependency:
There is an issue around currently for Red Hat based systems, Oracle Linux here, in version
219-30.0.1, having a
reboot seemingly hang on a failed swap unit (deallocation). A lot of posts on the net discuss the issue, After switching to Ubuntu 15.04 laptop won’t shutdown suggested the w/a, doing a
swapon bounce in advance, that worked for me, referencing reboot hangs at ‘Reached target Shutdown’. Systemd: Hangs indefinitely on >90% of reboot attempts comprises in in-depth analysis.
I’m not shure, though, whether tmp.mount.hm4: After swap.target is releated, really, because the implemented change is already present on my systems (
systemd‘s). I’m much more tending to suspect widespread storage fragmentation on the swap area to cause the relatively long term swap off run-times. In addition, I almost only experienced the issue for systems that have been up for a longer number of days, say from 90 days onwards.
