Also lots of locking up of the system and now as of today its stopped working altogether since the last update.What follows is an update on the situation, looking at both Fedora 20 and Ubuntu 13.10, and examining how far we have come, and how far we still have to go.
![]() Displaylink Linux Install Optional ComponentsWed recommend staying away unless youre an advanced Linux user who is willing to play with different distros, install optional components and do hand configuration. Unfortunately, its just not plug and play yet today, as it is on Windows. Our test systems included Intel, Nvidia, and AMD primary graphics adapters. For Nvidia and AMD, we tested both the open-source and proprietary drivers. Nvidia graphics cards, when running the open source nouveau driver, only work in Multi-Seat mode. Attempting multi-monitor setup with a DisplayLink adapter and an Nvidia graphics card results in garbage graphics being displayed on your DisplayLink-attached monitor. The Nvidia proprietary drivers do not work under any scenario. The AMD open-source drivers work under both multi-seat and multi-monitor setups, but the performance, at least in our tests, is significantly worse than with the Intel drivers. The AMD proprietary drivers are unavailable in any easy to install package under Fedora 20, but we installed them in Ubuntu, and were unable to get any results, they simply do not work with DisplayLink graphics. We noticed some regressions on Fedora 19, but these have largely been resolved in Fedora 20. Once this is done, DisplayLink graphics adapters will work in multi-monitor mode. Using a composited window manger(Gnome 3, Unity, Cinnamon, etc) will result in poor performance across all of your displays. Compositing re-renders far more pixels than non-compositing desktops. When youre just going through a GPU, youll only notice battery loss. But when all those pixels have to get processed by the CPU and sent over USB, its a huge hit. Toggling the screen on and off inside of your Display management UI usually solves this. Displaylink Linux Free To CommentWe dont recommend or support USB graphics on Linux yet, because of the problems above but if you do have questions, please feel free to comment below. We want to get as much information out as possible about what works and doesnt, so things can improve here. Theres no reason Linux cant have the same or better multi-monitor support as any other platform in time. If you can add your name and request for hardware here: we try to send out as much free hardware as we can. Thanks. With all the things mentioned here about the speed, but it works.
