TL;DR: Installed Ubuntu yesterday for the first time. When I use eGPU system gets sluggish AF. Don’t know how to even begin to try to troubleshoot. Should I look for help? Or should I get back to Windows, where I belong? ​ I’m a mediocre Windows user at best, even worse at macOS. I been using an Intel NUC Skull Canyon for the past few years with an eGPU (1070x AkiTio Node 3). My displays would occasionally shutdown or blink for a couple of seconds, but they would eventually come back on. It was rather infrequently, so I lived with it because as far as I knew I had all the latest drivers I could find at the time. I was under the impression that this issue was limited to using the eGPU (which I did, all the time, bypassing the iGPU 100% of the time). I figured if push came to shove, I could just plug one of my display directly into the iGPU HDMI port. Fast forward to a couple of days ago, and push came to shove in the worst kind of way. My displays are off most of the time occasionally blinking on for a second or two. I figured, no biggie, I’ll just use my iGPU, look up some drivers and get on with life. However, it turns out the iGPU is as bad or worse than the eGPU. The iGPU offers less on time because it flashes on less frequently than the eGPU -but neither situation is conducive to sufficient use time for researching and fetching drivers and whatnot. For a minute, I suspected maybe it was faulty hardware. As I investigated the situation, I wound up looking at the BIOS. While staring at the setting it dawned at me that it likely isn’t the hardware, since the display doesn’t shutdown on me while I look at the BIOS, so I did what any irrational person would do. I googled which Linux distro was the right one for newbs. Ubuntu came out on top, so I downloaded it using my laptop, put it on a flash-drive, and installed it on my NUC. As expected, it works fine with the iGPU. When I plugged in the eGPU, it quickly flashed a notification where it reported an unauthorized thunderbolt 3 blah blah… I couldn’t figure out where in the settings I could get at Thunderbolt or eGPU settings, so I decided to unplug and plug the eGPU in again, to provoke the message. It worked. It took me several tries, but eventually after several un/replugs I managed to quickly click on the notification, which then got me access to the Thunderbolt settings where I finally authorized my eGPU. It works. Kind of. The computer is impossibly sluggish when using eGPU for both displays. Sometimes one of the displays is fine but the other looks all kinds of wrong: bottom half is off and top half is distorted pixelation. ​ When I peruse settings, I don’t see an immediately obvious way to try to deal with this. I was wondering whether Ubuntu and I are a bad mix, because right now I don’t have the time to pore over manpages looking for the solution. Does anyone know if there is a quick fix for this? Or should I install a different Linux Distro? ​ Thanks! submitted by /u/Gavinaldi [link] [comments]
