Hi guys,

from about a week on my notebook tlp do not auto recognize ac/batt state and it don't auto load the config. If i restart the daemon manually after an ac/batt switch it will work well.

Any idea to fix it? I'm on a Lenovo G50-70

Greetings, Giuseppe

There's already a bug report about it [1]. I'm going to see to that tomorrow. Note that, for the same reason, tlp-rdw doesn't work as intended either.

Status update: The issue is caused by a change in udevd v221 making forked subshells unusable. Udev rules will need a non-trivial rewrite to work again. Thomas Koch (the author) has already made good progress, and restored correct behavior on battery events. However, there are still some issues with USB autosuspend and the exclusion of the usbhid driver, which could result in some unresponsive input devices. You can use tlp-git from AUR [1] until a fully working fix is available but beware of the aforementioned issues. In case you run into them, consider disabling USB autosuspend in TLP's configuration. Also forget about what I said about tlp-rdw, it is unaffected by the udevd changes, it was my mistake. [1] https://aur4.archlinux.org/packages/tlp-git Cheers, -- Maxime
