Raspberry Pi Desktop Computer 

Completed ... Solid, rarely tweaked - See Activity Log (below)

Recently replaced primary x86_64 Linux desktop with a RPi4 running Manjaro Plasma w/ SSD.  The little Pi is running surprisingly well - I've even done some video editing!  No step-by-step recipe here, simply an attempt to keep hardware & software profile up to date and possibly share hopes, dreams and struggles periodically - see Log below.

Migrated to new site summer 2021 - original  @ http://ventures.tpedersen.net/errata/raspberrypi/mipi

Project Status in a nutshell

Dec 2021:  New Card Reader & Case/Fan and ...
Issues!  MiPi is running hotter!  Some Freezes!
Feb 2021:  Tuneup:  MiPi RP4 is now overclocked. 

    config.txt:  over_voltage=6, arm/gpu_freq=2000/600

Jan 2021:  Had to print!  Forgot cups!  Manjaro Printing is not as easy as it should (Brother HL2395DW on network)

Nov 2020:  MiPi is now the primary system in my play-area ... Monitors, keyboard & mouse are front and center!

Aug 2020:  Manjaro is stable (again).  Now booting off of 240g SSD!  Slowly moving activities to MiPi.

Apr 2020:  Switched from Raspbian/Cinnamon to Manjaro/Plasma (64bit, Arch-based)

Level of Difficulty & Prep Time

Quite a bit of initial tweaking to get MiPi up and usable.  See Activity log below.  Probably not as time consuming today.

Manjaro ARM simplified the process significantly and is constantly improving - follow the project @ manjaro.org.  Moving closer and closer to 'Turn-key' desktop on an RPi.

Current Hardware/Software 

Software: Manjaro - RPi 4 KDE Plasma Version - Original Install/test notes.

Hardware:   RPi 4 Model B w/ 4g*

June 2022 - Update to 2022-05-31 Stable:  Mouse was skittish/sluggish, quick fix

Pretty big update .... details @ https://forum.manjaro.org/t/arm-stable-update-2022-05-31-electron-systemd-qt5-and-kernels/112504/4

Mouse was slow/skittish ... fix was in release notes:

Edit /boot/config/txt

#enable vc4

# TPed was here, changed fkms to kms below to fix sluggish mouse

December 2021 - New Hardware:  Different case + USB Card Reader, couple of software issues 

Couple of hardware tweaks (one in attempt to cool down the system, the other to simplify microsd imaging, I do a lot of that)

This thing has been running GREAT ... UNTIL ...  the past couple of weeks.  Now looking into a few of issues:

More to come 

April 2021 - Cosmetic touch-ups.  Libreoffice icons and KSystemLog

Finally getting around to fixing some cosmetic issues that have been bothering me

March 2021 - New Fan, Network weirdness, Samba issues and Tune-up, including final overclocking 

Fan started screaming!  It looks like they last approx 1 year!  Luckily, I bought a 2-pack.
I probably need to look into a better case w/ on/off switch, sleep mode or something

I'm not too sure about these constant updates ... periodically moving = one step forward, 2 steps back
March update #2, broke my Samba shares ... possibly the end to old client protocol (NT1).
This error when I was messing with SMB4k:

Mounting the share bshare on RNAS failed:mount error: Server abruptly closed the connection.
This can happen if the server does not support the SMB version you are trying to use.
The default SMB version recently changed from SMB1 to SMB2.1 and above. Try mounting with vers=1.0.
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Not sure Dolphin can even specify SMB vers=1.0 - https://bugs.kde.org/show_bug.cgi?id=339752

Another round of flaky wired network connection after a major update ... two issues here

Attempt to fix some annoying cosmetic issues and clean up warnings in logs ... I installed app called QT5 Settings ... THIS ENDED UP BAD!  Desktop icons disappeared and other strange visual issues ... undid it!  This is my reminder to see how all of the QT stuff fits together in the future

The QT_QPA_PLATFORMTHEME environment variable is not set (required value: qt5ct).


Everything has been running pretty well - time for a Tuneup!  Can't resist!

Exploring Overclocking ...

January 2021 - cups!  Printing
