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

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

Can somebody tell me, why the icon of this app does not appear in the

Suppose I start tde-networkmanager, say from the command line, it then

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.

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. 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. 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?"

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.)

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. 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,

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/.

But only the start icon.
Maybe we have a misunderstanding here.
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 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.
