From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

eGPU docks? (programming.dev)

Hi all,

Just wondering how progress is on eGPU docks? I want to upgrade my GPU at some point and thought it might be cool to put it in a dock and connect it to a laptop. The laptop has a couple thunderbolt ports.

How's compatibility these days?

Disclaimer: I have exactly 0 personal experience with eGPU’s.

According to the archwiki:

While some manual configuration (shown below) is needed for most modes of operation, Linux support for eGPUs is generally good.

Can confirm, I'm using a dock (from Razor) daily without problems. Hot switching doesn't work though, you need to restart X/your display manager to connect or disconnect the eGPU. I'd recommend the gswitch utility to configure the graphics card to be used (on X11). Haven't tested much on Wayland, but I know that at least Gnome (Wayland only) has trouble mixing eGPU and the internal display if that is important.

I don't think hot switching is an issue. It would be setup and not disconnected unless I'm traveling. Does it use the egpu for everything when its connected? Or can you set it up like hybrid where it'll only use it for games etc?

I use it for everything, because I connected my external monitors through the eGPU. https://wiki.archlinux.org/title/PRIME has a few methods for running only selected applications via the eGPU, but I haven't tried them. Edit: See also https://wiki.archlinux.org/title/External_GPU#Xorg for eGPU specific setups.

Perfect. Thanks!

If you use X and need to restart it, you can probably preemptively use XPRA to proxy your Xclients and move them to the new Xserver, except maybe for those that need low latency or DRM (e.g. games)
