Telegram is a cloud-based instant messaging service and is available for both mobile (Android, iOS, Windows Phone, Ubuntu Touch) and desktop systems (Windows, OS X, Linux). Users can send messages and exchange photos, videos, stickers and files of any type. Telegram also provides optional end-to-end encrypted messaging with self-destruct timers.
Tricks and Tips
Portable Version (Windows)
Windows Portable - So you don't have even bother installing it.
Currently only available on iOS, Android and Windows Phone, see here for details.
Launch Without Displaying Main Window (Linux)
Add the command line option
/home/user/Bin/Telegram/Telegram -startintray -- %u
Telegram will start minimised (using the option above) but will not open from the tray. To circumvent this issue in order on the menu:
Click 'Open Telegram' | Click 'Minimize to tray' | Click 'Open Telegram'
Yes it is a pain but after doing so Telegram will minimize/maximize on command.
Create Menu Entry (Linux)
Download and extract Telegram to the root of your user profile.
Create a dash/start menu entry:
nano .local/share/applications/telegram.desktop [Desktop Entry] Encoding=UTF-8 Type=Application Terminal=false Name=Telegram Exec=/home/username/Telegram/Telegram -startintray Icon=/usr/share/icons/suru/apps/scalable/telegram-symbolic.svg Type=Application Categories=Network;
Save (Ctrl+o) and exit (Ctrl+x).
