I think your L521X is sporting the older Ivybridge CPU correct? If it's got the new Skylake model instead they're having all kinds of issues atm with Intel fiddling around with the BIOS/UEFI updates. Either way, first thing I'd do is check that you've flashed the later version as a matter of course. Have you switched the ATA mode from "Smart Response" to "AHCI" in the BIOS/UEFI? That's required for Ubuntu to work on this model. Some XPS models don't like installing from USB boot media in the USB3 ports, so try the USB2 or the combo esata port you find on some Dells instead. Disable secureboot and check the CSM settings as well while you're at it - be warned, this can render your existing Win10 install unbootable (as can the ATA mode change) until you toggle the options back or reinstall Win10 with the new settings. All the XPS/Precision M Dell laptops I've used recently have switchable graphics (Optimus/Bumblebee) which absolutely blow under Linux. You might have to try different strategies depending on the model to get it to work including specifying no KMS on the grub boot stanza in the installer. Nouveau *should* support the onboard Nvidia card well enough to at least drag itself through the install wizard though. Have you tried any other distros? Something a bit more bleeding edge like Arch might have better support. But definitely check up on disabling Intel RST, I'd bet that's going to be your problem: http://ubuntuforums.org/showthread.php?t=2060108 Cheers -- The Mailing List for the Devon & Cornwall LUG https://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
