Emerge

Install net-im/signal-desktop-bin:

root #emerge --ask net-im/signal-desktop-bin

Troubleshooting

Failed to map segment from shared object

It is possible to get the following error when starting signal-desktop if /tmp has been mounted with the noexec mount option:

Uncaught error or unhandled promise rejection: Error: /tmp/.org.chromium.Chromium.xxxxxx: failed to map segment from shared object

To solve the issue remount /tmp without the execution restriction:

root #mount -o remount,exec /tmp

In order to make the change persist across reboots, it will also be needed to remove the option from /etc/fstab.

Unable to add attachments due to File Chooser not opening

If selecting the "Add attachment" icon (the 'paperclip' icon) has no effect, and doesn't open a File Chooser dialog, ensure that a xdg-desktop-portal frontend implementing the FileChooser interface is installed (e.g. sys-apps/xdg-desktop-portal-gtk) and that xdg-desktop-portal is configured to use it, via $XDG_CONFIG_DIR/xdg-desktop-portal/portals.conf:

FILE ~/$XDG_CONFIG_DIR/xdg-desktop-portal/portals.conf

[preferred]
default=wlr;gtk;gnome
org.freedesktop.impl.portal.FileChooser=gtk

Removal

Uninstall Signal Desktop by issuing:

root #emerge --ask --depclean net-im/signal-desktop-bin
