Matrix and IRC

From postmarketOS
Note Chat platforms other than IRC and Matrix are not official. We advise against proprietary platforms.

Please join our chat, so we can help you with using postmarketOS in real time. The chat is bridged between Matrix and IRC. We also provide an offtopic channel, which can be used to discuss your favorite pizza API and other non-related topics with the postmarketOS community.

Here's a list of channels. Either join them manually using a native client or click on the name to open a web client.

Topic IRC Matrix
Main channel, for user questions and general discussion #postmarketos
For device porting, getting kernels to compile, ... #postmarketos-porting
For discussing integration and development of systemd #postmarketos-systemd
For all other postmarketOS development, e.g. pmbootstrap, tools, ... #postmarketos-devel
Mainline kernel development #postmarketos-mainline
Bootloader hacking, assembly, etc. See also Category:Low-level #postmarketos-lowlevel
Announcements for maintainers, for testing new releases #postmarketos-release-party
Other topics #postmarketos-offtopic


Matrix client Element

In case you have no experience in using IRC, this is a method similar to mainstream chat platforms.

On postmarketOS phones, you can even try clients listed in Applications by category#Matrix.

The easiest is to join the Matrix space: (might not be supported by all clients). This groups all available rooms together.

After you register at any Matrix homeserver and join the channel, the offline history will be saved automatically. So, your questions can be answered even when you are offline!

Note: Our rooms are public & everyone can access the history even if you are not a registered Matrix user.


IRC client TheLounge

Point your client to OFTC using the following parameters:

  • Network address:
  • Port: 6697 (SSL)

The easiest is, if you're using a web client, to join all channels at once: join all channels On postmarketOS phones, you can even try clients listed in Applications by category#IRC.

Note Due to abuse, Tor users without a cloak are quieted. If you're connecting through Tor, you must register your nick and get a cloak before you can talk.

Help and guidelines for new IRC and Matrix users

As with every Matrix room and IRC channel, we encourage you to stay around for a while after you ask a question, and listen to the various discussions. Some people usually read everything that happens there, so it is likely that someone will answer you if they have the answer.

Due to this, please make extensive use of the off-topic channel to lower the noise in the others, and make the lives of those who read the entire backlog easier. Also note that everyone doesn't read every channel; if you want to draw someone's attention, type their name to ping them (doing this too often is considered rude, though). To prevent flooding the channel, please also use a service like instead of pasting your logs directly.

Remember that when you close your IRC client to go sleep, you miss out on half the planet. Please consider either setting up an IRC bouncer or using Matrix for offline history and better rich-media support.

Special note for Matrix users: You can set the notifications setting to "Mentions only" so that you will only disturbed when someone writes your name.

Register your username on IRC side

Some channels may not allow you to speak unless you register your nick.

  • Open a new chat with "NickServ" (Matrix: open a new chat with
  • Register your account by sending this to NickServ: register <password> <email> (example: register dhg235h234jbb
  • Verify your account at
  • Login by sending this to NickServ: identify <password> <nickname>

It's recommended to setup SSL CertFP on your client for automatic login. Instructions for IRC clients are here and instructions for automatic login (not SSL CertFP!) with Matrix are here.

Room robots

Rooms have a Matrix robot using the account which helps with administration (banning users, syncing rooms, etc.). Only team members can access the admin functions, but it will respond with useful context about pmaports issues or MRs if you refer to them by number like pma!345 for MRs and pma#567 for issues.
