Konsole: In KDE, both konsole and pull down konsole launch but when you enter text, it disappears after the first few words typed and and if does manage to take the command it does not print out any text…it usually causes the freezing before this but, if it does take it without freezing the systems text will disappear all together and eventually cause the system to crash. This is a confirmed issue that not only I’m having but two other friends that are this port as well…confirmed on not only there systems but also on the three of mine as well …both iBook G4 and PowerBook G4, both with clean installs, and PowerMac G5. Plasma-desktop meta packages install fine, but kde-applications , kde-networking, and telepathy-kde are broken on PowerPC32. I've confirmed this by installing the Plasma desktop and then kde-applications—errors saying too many dependency issues and does not allow the install to proceed on any of the three bundles of packages. The only successful set to install on clean system was the plasma-desktop bundle. Everything else has dependency issues, preventing further installation.

On top of that, I want to personally say thank you for everything you do. I was literally just talking about this project on the Arch Discord. Arch really should give this project more recognition and provide these as unofficial ports on their site, similar to how Debian does for ports. There's no reason that all this work should be shoved to the side. I don't know if you've seen Debian Sid lately on PowerPC, but it's an absolute broken package hot mess. Being able to install something and actually have the packages install is fantastic. I'm trying to find a good office suite to compile because LibreOffice isn't available. Any ideas, and I'm all ears. Appreciate you guys! When I get paid next Friday, I plan on chipping in some money. By the way, I have a last-generation PowerBook G4; it actually works really really well with KDE with the xf86-video-at driver. I know your mini has the Radeon 9200 in it but mine uses 9700 I know you said it was broken, but I've actually had decent performance with an SSD! Hoping the rest eventually will work. If there’s anything I can do contribute outside of me donating on Friday I am here for you guys as a Guinea pig.

I see some of the kde stuff is now in testing…do those get installed automatically or do I have to switch to the testing branch to install…sorry I’m coming from Ubuntu just wasn’t sure how the testing branch worked (still reading the manual on there wiki). Thanks in advance :)

@mrbubzie93 You need to enable the [testing] and [testing-any] repos that are commented in the shipped /etc/pacman.conf. Then just pacmna -Syu like you would on any Arch-like.

The new versions in [testing] to not solve the konsole issues though, I've been experimenting with debug builds but it's tough on 32bit systems with just 980Mbyte usable memory so haven't gotten any results other than finding out that drkonqi also can't submit crash reports on powerpc. :-/

Although I just installed the latest test, everything is actually working it’s really just Konsole, which is not a big deal because you can switch to the terminal when you're on the desktop with shortcuts. It's not really a big deal. It's pretty stable! I've been playing around with the testing branch, and I'm really happy with this and impressed. Power management is now working – I mean, it's still slow obviously, but you sir are doing the work of a god 😂. So thank you for making this possible. Couldn't get KDE under Debian, older versions of Kubuntu, or other PPC distro that offered KDE. This is absolutely insane how well it works on ancient hardware.

Just as a side note:

I'm currently working on Plasma 6 instead of fixing the old 5.x branch of things and the problem with Konsole seems to persist.

It's actually a two fold sword. I've been working on this on and off over the past month or so ($DAYJOB & $FAMILY).

qt6 has GPU accelleration disabled by default now as it was and always has been with qt5 as well (Void and a few others do this as well). Even so, konsole needed disabling the so called "BidiRenderer" to get it to work. I submitted a few crashes using drkonqi though in various circumstances. Let's see what comes off of that. (commit: 28df381)

When it comes to Plasma 6, which accelleration disabled in qt6 (commit: 34f0428) kwin_x11 can start on powerpc and render properly. Launch typical applications and all. However, startplasma-x11 won't work due to plasmashell crashing due to a buffer overflow pretty close to libc and I just haven't had the time to traverse the debug symbols down to what it could be.

My test chain for Plasma 6 is as follows:

  • launch X.org using the following .xinitrc
export QMLSCENE_DEVICE=softwarecontext
export QT_DEBUG_PLUGINS=1
KWIN_COMPOSE=N kwin_x11 &
#exec startplasma-x11 # the ultimate goal
exec xterm
  • launch prerequisites manually
/usr/lib/kglobalacceld &
/usr/lib/kactivitymanagerd &
  • launch plasmashell with debugging
plasmashell --no-respawn --qmljsdebugger

Hint: This won't be "fun" on actual hardware with less than 2GB RAM even when not using full debug symbols.

The lowest levels of the backtrace will get into libc territory where buffer overflow protection kicks in and kills the process. Someone with more time may want to have a look at this in more detail.

I am still open to it being a bug somewhere in Arch POWER of course and patches are welcome.
