I'm using a Lenovo ThinkPad X200s with Lubuntu. Yesterday I updated my system to Version 19.04, but the ThinkLight won't work any more using the short cut.

Trying to set it manually by changing to

/sys/devices/platform/thinkpad_acpi/leds/tpacpi::thinklight

and setting echo 255 | sudo tee brightness won't change anything. (But works).

Do I have to set anything new? Thank you

No changes - I assume the Update did something – Qohelet Jul 07 '19 at 08:02
You can install an older kernel version that had support: https://askubuntu.com/questions/119080/how-to-update-kernel-to-the-latest-mainline-version-without-any-distro-upgrade/885165#885165 – WinEunuuchs2Unix Jul 07 '19 at 14:29
