Tips and tricks

  • Sign in to multiple teams
    You can use the app to sign in to multiple Slack teams. Simply click your team name to open the Team Menu, then click Sign in to another team… to get started.
  • Use the Team Switcher
    If you’re signed in to multiple teams, you can easily switch between them by using the Team Sidebar. You can even use keyboard shortcuts Ctrl 1, Ctrl 2, and so on, to switch even faster. You can even drop the team icons to reorder them.
  • Launch Slack at login
    You can choose to have Slack start automatically when you log in to Linux. Just click your team name to open the Team Menu and select Preferences. Next, click the Linux App tab, and check Launch app on login.
  • Mark messages as unread
    Set a message as your oldest unread message from the comfort of your keyboard. Just press Ctrl Alt and click a message. 
  • Calls and spellcheck
    Slack Calls and spellcheck are not available on Ubuntu 14.04 — there are issues with the version of libstdc++ required for these features. As a workaround, you can use Slack Calls in Google Chrome.

 

Troubleshooting

Having trouble? Here's what to try first:

  • Refresh the app with Ctrl R.
  • Make sure you're running the latest version of the Linux app. Check for the latest version at slack.com/downloads.
  • If you're running into striations, pixelation, or rendering issues with the Linux app, try running "slack &" from the command line. If you're seeing better results, follow these steps:
  1. Go to "/usr/share/applications/slack.desktop"
  2. Change "Exec=/usr/bin/slack --disable-gpu %U" to "Exec=/usr/bin/slack %U"

You can also make a local copy in "~/.local/share/applications" and edit that copy.
