Desktop Config panel Bottom Section, Login Screen General: Uncheck Use Theamed Greeter Pretty much done, unless you want to fiddle with some other tabs. It then says Welcome to [machine] at [network] on the login screen.

Oops. These directions apply to 3.12, so you will have to look for the same settings in Leap.

Thanks John - I did find something like that, although I don't see an option for using no themed greeter. The default themes are pretty boring too. And slow - even just accessing the overview screen with the themes took more than a minute. @Felix, for testing I think I want to stick to sddm, the preferred DM for Plasma.

Revisting this thread:

I have not yet found an easy way to simply display the local hostname of the machine my leap 42.2 is running on. Fresh 42.2 install for example, the internet is not even straight about if its supposedly an sddm thing to look for or a kde plasma 5.8? thing or whatever. Is there a way to simply add the hostname, like that clock for example is showing the current time? I don't want to draw pixels or stuff, so I wondered if it was possible to simply display some user configurable text on screen?

Ah, sorry, I didn't read properly.

the problem here i describe is not a changing hostname of some sort. but to merely print some say courier fontfaced text with a constant string. pretty simple. but how to put it without editing the jpeg or whatever graphics files of some designs of kde and so on? how to only add some simple text ontop?

That is where I try to show a simple text for the user to be able to tell what machine she is accessing for example at the lock screen. Or better say logon screen.

How about replacing the default background picture? I think we can find a CLI command to add text to a graphic. Needs finding where the picture is saved or if it is configurable. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" (Minas Tirith))

You could also have a look at lightdm; that one displays the host name by default (at least on my Leap 42.2 test installation - where also XScreenSaver displays the host name on the (un)lock screen by default). -- Cahn's Axiom: When all else fails, read the instructions. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

yes indeed i found some other machine that had some previous open suse versions installed before and although it has itself arrived at 42.2 it was still using in etc/sysconfig/ displaymanager and windowsmanager some kdm and kde-plasma as settings/values, and it showed the hosts machien name on the logon screen which looks a bit different from vanilla 42.2 install state. what is the deal with kdm and sddm and this other setting my machines have had differing from each other: plasma5 and kde-plasma or so it was called. this is getting too complicated for me if i am not to read first the history of decades woth unix graphics stack land and linux land as well and understand all those components and bits and pieces of software. tia -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I asked the original question - I'm using KDE, sddm and no screensaver. If there's a man page that'll help me put the hostname on the login and lock screen, do tell!

Well , looking at the "sparse" docu / man-pages, (joke! I tell you.) even looking at the code upstream (https://github.com/sddm/sddm), it looks like either your theme provides a special space for the hostname, or you are out of luck. AFAICT, there is no theme that provides a placeholder for a "hostname". So, no-go with the hyped sddm for this case.

Well, yes. I even remember SUN workstations back in the 3meg Ethernet days that were 'roaming login' or whatever the term that Microsoft has made popular. The workstation was minimal and /usr (as the $HOME was termed back then) was loaded via NFS. I forget what else was loaded, but IIR the RootFS had lots of symlinks that became live when the login completed. I've also worked at places that supplied me with a laptop that had enough for me to do basic work on local files but also had that 'roaming login' to any part of the (multi-site) network. [As a sidebar, I'll mention that they ran SAMBA on a pair of HP-500 HP/UX series machines.] What is significant about that is that when I logged in the remote host not only handed out local shares and my network workspace and shared spaces, but also rammed some executables down. [That was fine so long as I was running the "Corporate XP". It was when I tried logging in with my own Linux laptop running a slightly alter model version of SAMBA that the problems arose :-(] I'm aware that the DHCP protocol and deal with hostnames in a number of ways. Either my "personalized" workstation can tell the DHCP server my hostname and it perhaps it responds in a custom fashion. Alternatively the server gives me a hostname for the duration of the session. In either case the hostname should be available before the login screen appears. Which gets back to the OP question of why don't the other login screen mechanisms, themes allow for the text to be easily modified. Rather than being simply declarative (as was the case with kdmrc) is now seems to be procedural, using QtQucik2. Yes, this means that it can be compiled with language packages, so we get lines like errorMessage.text = textConstants.loginFailed What was that about adding a level of indirection? And so too in, for example, /usr/share/sddm/themes/maldives/ Main.qml we find text: textConstants.welcomeText.arg(sddm.hostName) There is similar in the code for "breeze", but it is a procedurally more complex and obscure instance. All this is, I suppose, logical, a logical progression. An emergent property of internationalization. But it is also written in QtQuick2, so it means another language to learn, with its specific quirks. Why not something like Ruby, which I enjoyed learning and which we already have as the basis for Yast? Its already an interpreter. The QtQuick script reminds me of Ruby in many ways. I suppose the answer is that Ruby isn't a particularly fast interpreter because its a OO language. I think that's a weak answer. Whenever you are dealing with user input then the user typing speed is the limiting factor. There does seem to have been a trend among developers recently to move away from systems and details that are for the convenience of end users and administrators. The absence of the arrow icons at the end of scroll bars is one example of that which has already come up in other threads. Sorry to be so rambling.

It's all about finding out if you are on the right machine - for instance, when at a KVM with 8-12 machines attached, or in an office environment with 20 desktops. A quick check on the login screen will tell you if you are on the right one. Or you can tell support which machine you're trying to log into. Etcetera.

I had a look at "/usr/share/sddm/themes/breeze-openSUSE". There is a "theme.conf" file, which contains:

background=components/artwork/1920x1080.jpg

which is a relative path. In that location there is a symlink to the actual picture. So you just need to take the picture and add a text to it. No need to create a new theme, just alter one.

On every machine I install? What if the hostname changes?

As to the lock screen . what displays it? I think it is the screensaver. So just choose one that displays a photo. Can be a full black with a text.

I asked about screensavers a while ago, I'm sure I was told they're all gone. No need or no interest.

Perhaps you could create a script that hacks this in any machine reading the current hostname.

Hum. Good point. Then the script has to run on every boot, creating your copy of the background. On /etc/cron.d/something @boot, perhaps.

Make the theme point to your file (probably with sed or something), and make sure the file contains the correct text.

I'm sure I can solve the problem if I put my mind to it, but I want to keep things minimal and simple. It has to be repeated on every install and the list of customisations is only growing longer and longer. I was hoping to be able to add '$hostname' to some file somewhere :-)

Ah. Maybe on KDE, but certainly not on XFCE (and I guess Gnome). It is xscreensaver which locks the display for sure. I can see it in "ps afxu" output.

The software that locks the screen is still installed by default, but there is no "screensaver" in the traditional sense of the word: https://en.wikipedia.org/wiki/Screensaver

I don't run KDE, so I can't verify what app or thing displays the lock screen. What do you get when it locks, black? diplay powers off? What happens when you push a key, what do you get? A prompt text? No image?

When it locks, the screen goes black, later the monitor goes into power saving mode. When I hit a key, the lock/login screen is shown with the time and date and a field for the password.
