Fedora 28 ran great and the 4K screen is beautiful but the laptop had some issues so I sent it back. Issues: - the CPU throttles when putting it under load. The "fix"was to undervolt the CPU, turn off Turbo speed in the BIOS and turn off HT in the BIOS. This issue seems similar to the thermal problem the latest MacBook Pro had. IIRC Apple fixed it in a BIOS update. I don't know if/when Dell will fix it (or if they even can fix it). - fingerprint reader does not work. With the latest XPS13 (9370) Developer Edition, Dell "fixed" it by removing the fingerprint reader. - no separate PageUp and PageDown keys. The latest XPS13 does have them but on the XPS15 there were 2 gaps in the keyboard where those keys should be but aren't. - it's not possible to open the screen 180 degrees - the webcam at the bottom of the screen (aka NoseCam) is really annoying As an alternative to the XPS15 there's the new Inspiron 15 7000 series and the Lenovo Thinkpad X1 Extreme (though I have no idea if either of them runs CentOS 7).

I am running CentOS 7 on it. I was told that it has the same hardware of XPS 13. Most things work well out of the box: wifi, suspend-to-ram, HDMI output, Audio over HDMI, touchscreen, etc. I don't remember tweaking anything. The only thing not working perfectly I could find: the screen doesn't automatically rotate when being folded into tablet mode, but I just go into GNOME settings and rotate the screen myself. Not a big deal. Then I can watch Twitch using it like a tablet. I'd check the XPS 15's wifi module before buying it. The Inspiron 13 I have has Atheros, which doesn't require a proprietary binary driver. Intel's are even better. I know sometimes Dell throws in Broadcomm wifi modules, which require the proprietary wl driver. -- Yan Li
I have a Dell XPS 13 9360, though I am running ubuntu 18.04 on it.? I remember there being a patch to the mainline kernel which addressed many of the wireless problems. I'm not sure if those changes ever made it into the CentOS kernels. Some of the Dell XPS 13's had removable ethernet interfaces while most of the more recent ones had the killer interfaces on the motherboard.? I'm not sure about the 15 inch models.? Mine had a removable interface and I replaced the killer card with an intel card and that helped quite a bit. Regarding the CPU throttleing issue, there are a bunch of posts out there that claimed that the thermal pasted was not well applied to the CPU heatsink and some people had success with carefully removing the heatsink and applying a good quality thermal paste and then reinstalling the heat sink. Would be much better if Dell support would address these issues properly, but the response from Dell on these issues have been very hit or miss.? Some people have had them fixed by Dell and others, including myself never reached a customer support person willing to address them. Nataraj

Is anyone running Centos on the Inspiron 15 7000 mentioned?

Anyone running Centos 7 on this machine?
