KDE on Pi5

Hi, I used gentoo after I built a desktop with an AMD 650 about 25 years years ago... I am back at it, no longer using a stage 1, 2, and 3 to get up and running.... Alot has changed since then obviously, and now I use raspberrypi 4 as as NAS and put gentoo on the pi 5. The install guide wiki written by NeddySeagoon is excellent and gentoo is happily running on it. But, for the life of me I can't get KDE going. I compiled the latest raspberrypi kernel (6.6.22-v8-16k+) and uname -a confirms it is running that kernel. Dmesg shows that DRI, vc4-drm is initialized, fb0:vc4drmfb frame buffer device found, getfacl shows my username, yet xinit shows no screens found. The lspci -k command does not show any video cards, but I have evdev, libinput, v3d, vc4 and fbdev in make.conf and dtoverlay=vc4-fkms-v3d in config.txt. The error reads "Cannot run in framebuffer mode.Please specify BusIDs" What am I missing? Thanks

purdman10,

Welcome back. We knew your would come, just not when :)

The lspci -k command does not show any video cards

That's correct. There are no video cards on the PCi bus.

Code: Select all

dtoverlay=vc4-fkms-v3d

The f in fkms is for fake. The Pi5 does not support that. Remove the f and reboot.

Did you miss the xorg.conf fragment?

Yes, that is correct, thank you for your response. I added the 99-vc4 file yesterday and kde is up and running. My issue now is a block cursor that shows in miniature what is running in kde. I can't seem to remove it to any other "normal" cursor, using Wayland. In X I get a sometimes blinking. or disappearing regular cursor as it moves. I have tried to modify the cursor in /etc/environment adding KWIN_DRM_NO_AMS=1 to no avail.

May I suggest that NeddySeagoon extend your wiki to help others with the setting up a graphical environment? I had to relearn gentoo commands and setup on the pi 5 using your wiki guide but it took me about 5 tries to get into a gui. I used Sakaki's genpi64 build to get my feet wet, then went for a new install, compiled a new kernel based on Sakaki's wiki on install for gnome, then went work on KDE.

purdman10,

That might be a good topic for a subpage but for KDE its already covered by KDE except for the Pi5 specific part of xorg.conf.

The intended scope of the Raspberry Pi Install Guide at least in my mind , is similar to the Gentoo Handbook.
Its gets as far as having an install the can boot and build other things, with the twist that that it must not execute any target code.

Its a good place for random gotchas too, as installers will see them before they discover them the hard way.

Anyway its a wiki. The page started out in my namespace. When I had tested it on a Pi4 and Pi5 I moved it to the main wiki.
That makes it everyone page now.

Thanks for helping me and others in these forums!
