• If you run mongodb-compass on Linux desktop other than Gnome (xfce, KDE, etc.), you will encounter keyring issue and see this error:

MongoDB Compass has encountered an unexpected error: MongoDB Compass version 1.45.0
Stacktrace:

Follow this link and fix it:

• https://github.com/mongodb-js/compass/issues/1911
• Since I don't have GPU in my VM, I also add --disable-gpu.

mongodb-compass --disable-gpu --ignore-additional-command-line-flags --password-store="gnome-libsecret"
