Hi
I am running Ubuntu 16.04 and trinity.
There is an interesting app, called mathpix (which transforms png into latex)
https://snapcraft.io/mathpix-snipping-tool
It has to be installed via
sudo snap install mathpix-snipping-tool
I did this and when I start with ubuntu vanilla desktop I am able to start the app. However in trinity I find the start icon, in lost+found: I start the app
ps aux | grep mathpix
Tells me
oub 17567 0.1 1.7 3424960 143548 ? Sl 18:46 0:03 mathpix-snipping-tool
But nothing happens, no icon, no app is seen.
What shall I do?
Thanks

Hi Uwe,
Not a solution, but a starting point for getting it to work...
Go into the ubuntu vanilla desktop and copy all the settings and switches from wherever it's starting properly (menu item I'd guess?). Also, while in Ubuntu, start mathpix from the command line, using the command you copied, so you can see what is 'normal.' If it doesn't run, check/use the other menu item's setting/switches until it runs the same on the command line as the menu item.
Then, go into TDE and again start mathpix from the command line. If it works the same, then you can most likely manually create a menu item with all the copied information.
If that doesn't solve it, paste back the info from both the working Ubuntu command line and the non-working TDE command line. Also paste the results of "echo $PATH" from both desktops, just to see if it's a pathing issue.
Best, Michael

I had partial success. I copied the start icon

However now an icon should appear in the system tray (as it does in Ubuntu, say next to the network-icon, but it does *not*.
In Ubuntu that icon contains the interface, but trinity seems not to display it.
Last thing:
In /snap/mathpix-snipping-tool/36 I found command-mathpix-snipping-tool.wrapper
Which contains

Not sure what do with it.
So it seems that mathpix is not compatible with TDE, is this possible?

I realised that when mathpix is started I can use their key shortcuts Crt+Alt+M to convert math png to latex.
However there is no icon in the system tray, which is very unfortunate since, this icon would allow to configure the app.
Can somebody tell me, why the icon of this app does not appear in the system tray, but say the tde-networkmanager does?

This feature can be configured in the TDE Menu Editor. I forget if you can open it by run dialog, shortcut, or command, but it can be found by opening the start menu.
You can open the start menu, find mathpix (or any other program), then right-click on the icon. A little dialog with choices pops up:
<Add Item to Desktop> <Edit Item> <Put Into Run Dialog>
Click on the second choice, <edit item>, which takes you to the TDE Menu Editor for that program. Among the choices you see is a box with the label <Place in system tray>
Click that box; then be sure to choose <Save> or <Save and Quit>. (Look under the heading <File> at the left top corner.)
And now you should have it.

HUH. Okay, now you got me.
This may take more investigation. I don't generally put items in the system tray myself, and don't use mathpix (yet), but so far it always works for those few items that I *do* put in the tray.
I'll look into it tomorrow, as it's late here. Or maybe somebody else will know more.

Thanks! I really would appreciate any help. The app itself is very easy to install via snap (and quite cool I must say).

Another thing that you can try is to right-click on the system tray itself and unlock panels. Somewhere there is a dialog that allows you to add an item to the system tray.
You can add program, applet, whatever, but again, it takes some searching. However, I avoid touching my system tray once I have it set up - not even what I'm telling you now - because it invariably messes up everything, and takes for ever to get it back. All my icons are shifted round, etc., etc., etc. .... And once you get it set, lock the panels, and leave your tray alone!
Also you can add a quick launch folder to the tray.
If this doesn't work, then I must wonder if there is not some other issue. Another oddity: I did a quick search using apt-get, and mathpix doesn't come up. I am running Devuan Jessie, so maybe it's just not in those repositories.

Suppose I start tde-networkmanager, say from the command line, it then appears in the system tray, where I can access its configuration, that is to which wifi net I want to connect.
I want the same for mathpix, I can start it, but it does not appear in the system tray, and that is why I can use it (via its shortcuts) but not configure it because I cannot access the configuration menu.

It is not you have to install it via snap (so you have to install snap first) once you have installed snap, then
sudo snap install mathpix-snipping-tool
Will install it.

Okay, now I'm the one who needs help.
I am not familiar with snap, but it's always good to learn new things. So I did install it, then tried the command that you gave me to install mathpix:
sudo snap install mathpix-snipping-tool
And all I get are errors:

No, and I am sorry, but maybe this will not work for me. I run Devuan, so I can manage with Debian packages, but sometimes not Ubuntu. My apologies ...
When I search these other snap packages (listed above), I get tons more that will be installed, and I certainly don't want them all. It is against my religion to run non-free or proprietary software, although now and then I bend the rules a little for testing purposes, to solve some temporary problem, or just because I am too curious.
Maybe somebody else here can help you? somebody who runs Ubuntu and can install these packages?

Ok I understand. I usually share you philosophy but sometimes are hypocrite enough to install non free software (if is as cool as mathpix, well I have to see how often I will use it)

It seems that the problem I reported is not restricted to TDE, in XFCE it also does not work. So the mathpix guys did something very Ubuntu specific. sigh

Yeah, when I saw all those Ubuntu packages, I knew it was something like that. I gave up on all the 'Buntus a few years ago, although it was a good place to start and learn; but towards the end, it was becoming like Windoze Lite, and I spent a lot of time trying to figure out how to get my system *not* to contact Ubuntu or others without my permission ... and if I wanted all that "help" without my permission, I would still be running Windoze.
I am watching for the same thing to happen with Debian (like with the systemd controversy); so once again, I changed to Devuan.

In other words, in whatever Ubuntu's default desktop is these days, starting the program places an icon in the system tray which provides right-click or drag-and-drop functionality that goes beyond starting the program, and which you find useful.

I checked the developer's website ( mathpix.com ). The application appears to be closed-source. Snap ( snapcraft.io ) is a distro-hostile "universal" installer program that I wouldn't touch with a barge pole, and the developer's site does not offer the Linux version for download in any other format. Furthermore, the file it does offer is labeled as being for Ubuntu, which with people like these who probably don't know much about Linux means they only tested it on one version of the distro, and with all-default settings. They will not have tested TDE. They will probably not even have heard of TDE.
My guess would be that this thing is calling something that's specific to the default Ubuntu desktop rather than following the XDG specification for system tray icons (yes, it seems there is one). At this point, I'd install a third desktop environment (possibly XFCE or Lumina) and see if it works as expected there. If it doesn't, complain to mathpix.com that their application doesn't follow standards and hasn't been properly tested. If it does, well, we've at least narrowed the problem down to "what do these DEs do that TDE doesn't?"

Thanks for the heads-up on this one. I installed snap just to test this mathpix thingie, but it didn't install any other packages, so no harm done (I hope). I finally got my system running GNU/Linux with all free/libre software (not sure where TDE stands on this ...), so I wouldn't want to keep it on my system.
I don't mind testing, though, if it might help others.

As far as I know, the snap application itself isn't harmful, but it bypasses your distro's package manager, which is a recipe for all kinds of potentially bad things and just general weirdness. I've never looked into it in enough depth to find out whether it has any kind of license enforcement or whether anyone other than the person who packaged the program tests this stuff (my guess would be no and no). The only reason it exists is to allow people who want to write closed-source software for Linux to create only one package instead of having to produce a .deb and a .rpm *and* a properly versioned list of dependencies, oh the horror! ('Scuse me while I roll my eyes.)

In other words, in whatever Ubuntu's default desktop is these days, starting the program places an icon in the system tray which provides right-click or drag-and-drop functionality that goes beyond starting the program, and which you find useful.
Another oddity: I did a quick search using apt-get, and mathpix doesn't come up. I am running Devuan Jessie, so maybe it's just not in those repositories.
It is not you have to install it via snap (so you have to install snap first) once you have installed snap, then
sudo snap install mathpix-snipping-tool
Will install it.
I checked the developer's website ( mathpix.com ). The application appears to be closed-source. Snap ( snapcraft.io ) is a distro-hostile "universal" installer program that I wouldn't touch with a barge pole, and the developer's site does not offer the Linux version for download in any other format. Furthermore, the file it does offer is labeled as being for Ubuntu, which with people like these who probably don't know much about Linux means they only tested it on one version of the distro, and with all-default settings. They will not have tested TDE. They will probably not even have heard of TDE.
My guess would be that this thing is calling something that's specific to the default Ubuntu desktop rather than following the XDG specification for system tray icons (yes, it seems there is one). At this point, I'd install a third desktop environment (possibly XFCE or Lumina) and see if it works as expected there. If it doesn't, complain to mathpix.com that their application doesn't follow standards and hasn't been properly tested. If it does, well, we've at least narrowed the problem down to "what do these DEs do that TDE doesn't?"

Another reason to avoid snap, Docker and the like is that they typically include all of the associated libraries that the application uses in a package, and are intended to be installed into an individual's home filespace. That's fine for a system with only one user defined, but not so good if it has multiple users, where it would be better if the application used the system's shared libraries and installed into e.g. /usr/local/.

I contacted them and yes this is my impression too.

Good, idea. I installed XFCE and the same problems occur there. So it seems that mathpix did something very specific for Ubuntu.
