    Ubuntu 18.04

    Works flawlessly. Battery life isn't great (about 4 hrs). Could be the FHD touchscreen or the non-OEM replacement battery.

    1. 19.10, 18.10 and 18.04, all worked
    2. Dell
    3. E7440, rest of the details in my signature.

    The only thing I haven't tested is HDMI.

    General advice for laptop users: Keep your BIOS firmware and OS up-to-date. Create a separate partition for future upgrades: You can download any Linux distro ISO file there and let GRUB boot it (GRUB can boot any ISO!), thus no need for USB stick, external disk to install new Linux distro. Use UEFI. Usage of rEFInd to combine several OS is tricky. Use separate GRUB config files for each distro, don't use one for all, because everytime when a kernel is updated, GRUB must be modified in that distro which will be inconsistent in the other(s).

    To get maximum performance from a laptop with SSD like and increase its hardware life time: use lightweight distro (Lubuntu), reduce swap usage by adding vm.swappiness=1 to /etc/sysctl.conf, uninstall as many programs as possible. Almost all of the systemd services are needed - no chance there. Keep cron, anacron, postfix running. Disable harddisk cache, enable memory cache for Firefox - this will reduce continous SSD activity. You can use tmpfs (RAMDISK) for any purpose! Check your dmesg and /var/log/syslog from time to time. There might be chance to uninstall or configure a package to fix or speed up.
