  • Application share (Wayland)

  • Optimization for image/text or video when sharing your screen

  • Remote desktop control

  • Device connections

  • Virtual background

  • Hardware acceleration

  • Background noise removal

  • Call control of third-party headsets

  • Voicemail (Unified CM)

  • Contact Center support (Unified CM)

  • Webex Calling

  • Webex for Service Providers

Linux distribution support

We support the following distros:

  • Ubuntu 18.04 and Ubuntu 20.04

  • RHEL 8.2 and 8.3

Recommended minimum system requirements

  • Core requirements: Intel Dual-Core CPU 2.XX GHz or AMD processor (4 GB of RAM minimum recommended)

  • Display Protocols: x11 and Wayland

  • Desktop environment/Window Manager: GNOME/Mutter and KDE/KWin recommended.

Accessibility

To support the Orca screen-reader, you must include ACCESSIBILITY_ENABLED=1 in your environment.

Known issues

  • Currently only 16-bit depth audio input is supported. Microphones with 24-bit sampling aren't expected to be compatible.

  • Users on tiling window managers, such as i3, may experience focus issues when trying to search. It may require several mouse clicks into the search box to regain focus after typing.

  • Configuring proxies using KDE System Settings is not currently supported.

  • Linux clients aren't supported for end-to-end encryption.

  • Changing scaling using fractional scaling in the system settings isn't supported.

X11 limitations when sharing your screen or application

  • You can see the share control bar but you're not able to preview your share from there.

  • When you share certain applications, such as Google Chrome, the red border displays a shadow effect around the application window.

  • You're unable to change your system display settings while sharing your screen or application.

  • The resolution of the area you're sharing must be less than or equal to 4096 x 4096 p, regardless of what you're sharing.
