Have the telegram-desktop installed via pacman on the Arch Linux.
After starting – no systray’s icon present and thus can’t see new messages and even can’t exit in a normal way.
This issue is not specific for the Arch Linux and happens on any Linux systems.
Go to the Google and make search with “telegram linux no systray” – the very first result will lead you to the 2017’s year discussion on the Github.
So the solution is just to install the sni-tq:
[simterm]
$ sudo pacman -S sni-qt
[/simterm]
Kill Telegram:
[simterm]
$ ps aux | grep tele setevoy 3754 0.2 2.0 2382584 331040 tty1 Sl Feb26 13:58 telegram-desktop $ kill 3754
[/simterm]
Re-run it::
[simterm]
$ telegram-desktop
QApplication: invalid style override passed, ignoring it.
Available styles: qt5ct-style, Windows, Fusion
(process:21848): Gtk-WARNING **: 12:03:52.331: Locale not supported by C library.
Using the fallback 'C' locale.
[/simterm]
Done.
