I can’t say about QC since merger. His LT is from late 2017 and came with Ubuntu 16.04 LTS installed (current model is 5530 with 18.04 LTS). My gripe is that the OS is a Dell spin, so it lacks features and ability to install other features. For example, I could not install GParted in order to partition the SSD to move /home. The spin has app called Disks which I could not figure how to partition. I ended up using live USB of Kubuntu with KDE Partition Manager which did the job easily. I probably need to get familiar with partitioning with fdisk.
Another gripe is that after restore and running apt-update leads to a core dump! There’s a fix for it, but I’d forgot that we saw this when we purchased and set up previously. My son remembered. IMO, that’s just crap. Ubuntu should be drop-dead-simple to install.
3rd gripe, Dell spin of Ubuntu (Unity) does not enable the meta (windows key) to display Unity Dash. Again, there’s a rather non obvious workaround to make it work correctly. One headache after another.
If this were my PC, I would nuke every bit of Dell software and pave with Kubuntu. I’m hoping that my son will embrace a nuke and pave with Ubuntu 18.04 or PopOS or Kubuntu before he heads off to College in the fall. And on that point, let me brag on his accomplishment of being accepted into the class of 2023 at Cornell. He is thrilled. Will major in physics.
