4/17/2023 0 Comments Displaylink usb graphics r7 370![]() ![]() Nvidia’s and AMD’s proprietary drivers are still entirely incompatible with DisplayLink graphics on Linux. Toggling the screen on and off inside of your Display management UI usually solves this. When rebooting your Linux computer, or simply logging out and back in, your USB-attached displays will not always come back without having to disconnect and reconnect them.Ĭhanging the location of your DisplayLink screens in your virtual desktop can sometimes cause strange issues (like only half of the monitor rendering). Unfortunately, due to the discontinuation of Gnome 3’s fallback mode, that is no longer an option for improved performance.īesides the issues I mentioned above, there’s still a few other problems. Switching to a lighter-weight window manager or desktop environment (XFCE, LMDE, Mate, etc) results in a quite usable setup, provided your main display adapter is a recent Intel chip. But when all those pixels have to get processed by the CPU and sent over USB, it’s a huge hit. When you’re just going through a GPU, you’ll only notice battery loss. ![]() Compositing re-renders far more pixels than non-compositing desktops. Using a composited window manger(Gnome 3, Unity, Cinnamon, etc) will result in poor performance across all of your displays. Performance continues to be an issue with DisplayLink on Linux. ![]() You can also keep track of the USB Graphics situation under Ubuntu in this blueprint. It should be noted that the reason this is necessary is due to the Ubuntu team making some changes to the kernel that they ship with Ubuntu, resulting in broken DisplayLink graphics support. Simply enable them from System Settings like you would enable any extra monitor attached to your PC.Ī step-by-step guide to accomplish this will not be provided because switching away from your distro-provided kernel is something only expert users should attempt. Once this is done, DisplayLink graphics adapters will work in multi-monitor mode. In order to enable DisplayLink adapters to work on Ubuntu, one must download the latest Mainline Kernel build from the Ubuntu Kernel PPA, install it, and then reboot with that kernel. Ubuntu still has several issues with DisplayLink graphics, and they do not work out of the box. You should be able to connect one of our docking stations and create a plug-and-play multi-seat setup, or connect one of our display adapters, and expand your desktop to an extra monitor using the Arandr utility, or something similar. We noticed some regressions on Fedora 19, but these have largely been resolved in Fedora 20. 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.įedora has always provided the best support for DisplayLink graphics on Linux. 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 Nvidia proprietary drivers do not work under any scenario. Attempting multi-monitor setup with a DisplayLink adapter and an Nvidia graphics card results in garbage graphics being displayed on your DisplayLink-attached monitor. Nvidia graphics cards, when running the open source nouveau driver, only work in Multi-Seat mode. Intel is the most compatible, providing decent results under all configurations. For Nvidia and AMD, we tested both the open-source and proprietary drivers. Our test systems included Intel, Nvidia, and AMD primary graphics adapters. We used all Plugable products in the tests for this post. That said, it is possible to get things working in limited scenarios for USB 2.0 generation DisplayLink-based adapters. Unfortunately, it’s just not plug and play yet today, as it is on Windows. We’d recommend staying away unless you’re an advanced Linux user who is willing to play with different distros, install optional components and do hand configuration. You can find many distros and configurations where it just won’t work. Multi-monitor on Linux, especially with multiple graphics cards and USB graphics adapters, remains problematic. 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. A little over a year ago I wrote a blog post discussing the state of USB Graphics on Linux systems, specifically, Fedora 18. ![]()
