Re: [Bug 791833] Re: Dell ST2220T Monitor responds totouch only on warm boot from windows



this is the first time Benjamin and I hear about this device. From the report descriptors we found in a forum, it looks like the device should work properly with the latest version of hid-multitouch (patches submitted by Benjamin last week). To check this, one would just need to list the vid:pid of the device in has_special_driver in hid-core.c, then recompile/reinstall the hid module.
