Release Linux driver source code to the community
Your "Ubuntu" driver package works inconsistently, fails every time there is a system update to the kernel or the X server, and performs badly. It's clearly not a priority for your development team, who likely have orders to focus their efforts on the larger market-share platforms. The open-source community is packed with talented developers who will work for free to help you deliver a more polished product, providing a better experience for your users, and ultimately resulting in more product sales.
I fully agree. I really like some of the DisplayLink products (e.g. ASUS MBR16AC). However, driver support for Linux is completely inconsistent. As a consequence, I don't buy DisplayLink products for my company.
