Now I don't know if the above driver would not work as well. File "/usr/bin/validity-sensors-firmware", line 59, in download_and_extract_fw

raise Exception('Hash mismatch for driver download!

It would be the driver from 3/23/2023 from Lenovo and in the ppa the last update was in 2022.

But thanks for the tool - it works also with the older driver.

Hi Arnold, the only thing python-validity is using from the Windows driver is a firmware file. Chances are, the new driver contains the same firmware file. And even if it's not the same, it may still still work fine with python-validity. Can you check and if it does work raise a PR to change the checksum?

Ok the firmware in the update from 23.3.23 is probably a different one - I have now only commented out the hash and then comes
