From ArchWiki

Telegram is a cloud-based cross-platform instant messaging service with optional end-to-end encryption. Account creation requires a phone number.

Note: Although the telegram client(s) are open source, the server side is proprietary and centralised, therefore having privacy issues. Use at your own risk as data is controlled by a centralised company.

## Tips and tricks

### File chooser style

See Qt#Configuration of Qt 5/6 applications under environments other than KDE Plasma

### SVG icon theme in Telegram Desktop

This article or section is out of date.

Reason: telegram-desktop depends on qt6-svg (Discuss in Talk:Telegram)

If you want to use an icon theme based on svg image (e.g. papirus-icon-theme) install qt5-svg. See Qt#Icon theme is not applied for details.

### Wayland support

See GNOME/Troubleshooting#Cursor size or theme issues on Wayland.

See Wayland#Qt for generic instructions.

### xdg-open scheme handler

If you want to use xdg-open for `t.me` links and receive an error not finding a handler for `tg`, run:

    $ xdg-mime default org.telegram.desktop.desktop application/x-xdg-protocol-tg
    $ xdg-mime default org.telegram.desktop.desktop x-scheme-handler/tg

### Real-time priority

This article or section is out of date.

Reason: Latest openal supports rtkit that allows to set priority for unprivileged processes (Discuss in Talk:Telegram)

If you get the following error:

    $ telegram-desktop

    [ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)

Install realtime-privileges, add yourself to the `realtime` group and reboot. See Realtime process management#Configuring PAM for details.

### HiDPI scaling

The factual accuracy of this article or section is disputed.

Reason: This may lead to problems when opening files from Telegram (e.g. opening pdf with Okular will inherit the variable). (Discuss in Talk:Telegram)

This article or section is out of date.

Reason: These instructions are likely not relevant to the modern Qt (Discuss in Talk:Telegram)

If you have Qt scaling enabled on your system, and the scaling factor is not an integer, you may encounter problems like pixelated images and icons. you may need to disable high-DPI scaling for Telegram separately.

Unset `QT_SCREEN_SCALE_FACTORS` environment variable as follows:

    $HOME/.local/share/applications/org.telegram.desktop.desktop

    ...
    Exec=env -u QT_SCREEN_SCALE_FACTORS telegram-desktop -- %u
    ...
    DBusActivatable=false
    ...

You may need to perform Desktop entries#Update database of desktop entries afterwards.

Also consider disabling Default interface scale in Settings and enabling Enable precise High DPI scaling in Settings -> Advanced -> Experimental settings to avoid incorrect scaling when launch by `xdg-open` (e.g. opening `tg://` link).

### Audio backend

As Telegram makes use of OpenAL, it is possible to configure the audio settings by editing its config files, i.e. `~/.config/alsoft.conf`, or the environment variables listed here.

In case sound is not working due to an invalid audio backend being used, it can be overwritten by setting the environment variable `ALSOFT_DRIVERS` or the `drivers` property in the `[general]` section of the OpenAL config. The drivers value `"pulse,"` for example would try pulseaudio first and then fallback to the default driver list.

### Fcitx support for Qt 6 Telegram

Telegram-desktop is built against Qt 6 since 3.4.2-2. Users upgrading from an older version might notice Fcitx stop working for this application. To make it work again, install fcitx-qt6 or the fcitx-im group. If using Fcitx5, install fcitx5-im.

### Changing the default file browser

Telegram Desktop uses the File Manager DBus Interface to open the file browser. The spec does not allow to choose the preferred one, ensure you have only one file browser installed.

Do not confuse file browsers with file dialogs which are parts of toolkits and is covered by #File chooser style.
