On 10/31/2025 at 1:32 PM, Jean-Francois Lessard said: Latest driver version now use line-display library (expected upstreaming requirements), therefore there is no more sysfs value attribute. This has been replaced with the line-display message attribute. @snowbody you are using an older version of the driver with the current version of the display-service. That won't work. Since you are on 6.12 kernel, start by cloning the main branch of https://github.com/jefflessard/tm16xx-display.git it already contains the line-display backport. 0 Quote
