I don’t know about Linux support since I have to use Windows on it but oh boy it is crap. The fans are always on whatever you do, the left part of the keyboard is frequently burning hot. Touchpad is mostly really good … when it works, because as soon as I wash my hands, it stops detecting anything. The audio part, at least on Windows, is pure random. USB docks randomly works and once a USB-C device is plugged in you are good for overheating near the connector.
For me it’s total garbage and I’m just waiting for it to die and my employer to change it for something better.
Our newest Dell laptops looks good but I’m never trusting this company again.
