[$] Synaptics patent claims stop work on DisplayLink drivers

Mike Lothian owns a docking station (or dock) that uses a DisplayLink chipset that had, at least in his opinion, subpar performance on Linux. He decided to try improving the Linux driver, with LLM assistance, but ran into one problem that he could not solve—so he asked for help, hoping that Synaptics's developers would lend a hand. (DisplayLink was acquired by Synaptics in 2022.) Rather than help him in improving the driver, however, the Synaptics legal team responded with patent infringement claims, a demand that he cease unauthorized implementation of DisplayLink technology, and threats of expensive legal penalties. For now, it appears that Linux users of the company's docks will have to continue to live without feature parity with other platforms.
