What is the "root" user account password?
I browsed through this thread, and it seems to been asked, but never answered.
He usually gives it in the README info on his github, or it can be found on the Software Releases wiki page. It may still show an older version, but the login is unlikely to be changed.

IIRC the default root password is unset.

You're right, I must've been thinking of the default user.

This is definitely the best OS for the Pinebook Pro so far. Does anyone have any tips for eliminating screen tearing?

That’s work fine for me. I was concerned that all the required packages might not be present. However if the are all there, I have no issues installing in this manner.
Ditto- the bionic-minimal arm64 (for rockpro64) worked for me, though I used tasksel and then just grabbed the board support packages for PBP afterwards.
Added bonus: Signal Desktop is _much_ easier to build on arm64, there are semi-regular third-party Tor Browser builds, and building a custom kernel would likely be easier, too (though I haven't needed to do so yet).

So apparently the APIC on rk3399 doesn't handle interrupts broadcast to multiple cores very well. When it receives a broadcast interrupt for multiple possible cores it just hands it to the first core in the given range without broadcasting to all of them. The default range for interrupts is set to all cpu cores (0-5) so almost all interrupts are presently being serviced by poor frequently-interrupted cpu0.
I tried running irqbalance last night to solve this easily but apparently irqbalance also likes to assign ranges of cpus or it's otherwise not functional out of the box without :effort: so I cribbed some of armbian's simple boot-time performance code and distributed interrupts manually. Desktop performance is noticeably less laggy, and while it's not anything amazing it's a decent improvement.
If anyone's interested in trying this out here's the irq assignment script and boot-time service file:
https://gist.github.com/foundObjects/76d72917f348b04b3a75c781e80f1eb8
Instructions are commented in each file. Comment out the root remount line, you probably don't need it. You might also want to juggle the cpu cores pcie, mmc1 and USB3 land on depending on which you're using on your system. Cores 0-3 are the little cluster, 4-5 big.
This really isn't the optimal way to distribute interrupts but it's better than nothing at all, let me know if there's anything obvious I missed.
edit: If you just want to try this out without installing it for every boot just read the script then run it once as root, interrupt assignment only stays in effect until reboot.

@Arglebargle, Thank you. Quite interesting.

Code:
echo 1 > /sys/devices/system/cpu/cpufreq/policy0/interactive/io_is_busy
echo 1 > /sys/devices/system/cpu/cpufreq/policy4/interactive/io_is_busy Perhaps replace the governor directory with *.

If you want to install the latest KDE, follow these steps: https://forum.kde.org/viewtopic.php?f=309&t=135278
I tried it just after installing Ubuntu MATE and it works, it looks like I have KDE Neon. Not rock stable, but it runs fine, only a few apps are crashing, but not too often.
RE: 0.9.14 Release: Ubuntu 18.04 with Mate & LXDE Desktop - stealthbanana - 11-26-2019
I've been running Neon for the last few weeks, and almost rock solid. Could you try something for me?
Open Konsole and use the dmesg command. Does it crash Konsole? Works fine with any other terminal emulator showing there was an alignment fault.
I'm using the 32bit version as I like to watch Netflix, but have installed the 64 bit on an SD card, works just as well, no real performance increases in use, but that may be down to the speed of the card I am using.
