Hi Guix, I have a computer with the MATE desktop environment. My previous system generation was from May 25 on commit 22c229ff4e0869cdbcd5eabbe482fde7725e75e1, I just upgraded my system to commit 2d418933a46a92a545ccebe629470af0fc019c4b (from 3 days ago).
After rebooting and opening a MATE session, I have a repeated popup message saying "Authentication is needed to run /gnu/store/ra8zy5yqsq1k21ffxkjv7jd8mwczm2j4-mate-power-backlight-helper' as the super user" and asking me to type my password. If I do so, the popup may come back immediately 3 or 4 times, then again after something like 10 to 15s. When clicking on "details" in the window, I have additionally: polkit.subject-pid: 2205 polkit.caller-pid: 2498 Action: org.freedesktop.policykit.exec Profider: The polkit project The process with pid 2205 is mate-power-manager and the process with pid 2498 is mate/power/backlight-helper. Before updating the system, I had never seen that. My very rough understanding is that polkit is something to get permission to do some actions that may require superuser rights, from processes without superuser, and that some rules need to be configured for that, so it looks like some rule might be missing. Could it be that some new version of some part of the MATE environment requires some new rule, but that rule is not setup automatically? Or is it another problem? Note: I have manually copied the references to the commits (this email is not written from the concerned computer, as I haven't installed email on it yet), so there could be some mistake in the references. Thanks for any advice. David.
