I’m showing 262144 Total and 65500 free with just terminal and firefox open
With cma-384 and a 4K monitor, I have:
CmaTotal: 393216 kB
CmaFree: 115964 kB
Let me try adding that.
ok so no change solely adding cma-384. Still shows 262144 kB
Tried adding your line dtoverlay=vc4-kms-v3d-pi4,cma-384
and now my TV reports resolution not supported… hmm
Test 2: Chaning to vc4-kms-v3d
only results in hanging at Starting TLP system.
Ok back to FKMS driver, had a space in there but now the CMA-384 is working properly. Still no thumbnails in widgets.
I think you need hdmi_group in addition to the hdmi_mode. If your hdmi cable is bi-directional, I would try removing the hdmi_mode and let the driver read the TV/monitor.
Grrr…
Did you try picking a different Plasma Style?
Yeah I did. I’m wonder if it could have any issues with the color space? I had UHD color set on the TV but just turned it off. no change. tvservice reports state 0xa [HDMI CUSTOM RGB lim 16:9], 3840x2160 @ 60.00Hz, progressive
Trying to decode the edid again.
I even tried switching to testing, updating, and tried installing QT6.
EDIT - - There’s no edidparser package … hmmm
I know I’m being picky and can just switch to conky or run XFCE instead, but I’m hoping that I found some kind of bug and can help out the community if we can get it solved.
Making some progress…

Things that make you go hmmmm
I cannot believe it… I got the thumbnails to show up in add widgets. However in all my testing, I broke the system monitor widgets lmao. I know I made progress because the Y-axis bars are there in the widget.
What I think finally fixed it was the commenting out QT_QUICK_BACKEND
in /etc/environment
but I changed that after I installed mesa-git and vulkan-tools. The problem is I also updated pretty much everything else to the -git variants. At least all of KDE, KF5 and plasma.
I also updated my config.txt to have gpu_mem=128
and cma-512
so TBH I don’t know what fixed it, but without doing a complete reflash I won’t know which one actually fixed it.
I’m going to reflash again fresh, stay on stable, update everything, and change just that to see if that does it.
YASSSSSS!
OK Folks. Here it is!
Fresh Manjaro Arm Install
- No Widget thumbs
Edit config.txt
Add cma-512, 4Kp60, hdmi_mode=97, hdmi_force_hotplug, overclock
- No widget thumbs
Update to mainline kernel
Run system updates.
- Flickering Screen.
SSH in and tvservice -p
System Settings → Display Settings → Set to 3840x2160 @ 60Hz
- Still No Widget Thumbs
Comment out QT_QUICK_BACKEND=software
Log out, Log Back in.
- WIDGET THUMBS ARE THERE!
- NETWORK SPEED WIDGET WORKS!
Yeah.
The Graphs need hardware acceleration probably, so by removing the QT_QUICK_BACKEND
thing from /etc/environment you enabled that.
I’m gonna put together an ultimate RPI4 desktop replacement HOWTO for here and I’ll make sure to add this information to it.
@Strit I just set up my VirtualBox VM with all the manjaro arm tools. Is this something that should be defaulted in the installer?
We are working on a plymouth screen, but yes, we will do this by default now. Last we tested, hardware acceleration didn’t work on the V3D driver yet. But I tested some stuff the last couple of days and seems to work pretty well now.
@Strit Awesome. I’d love to help, even if its with new background graphics or some fun stuff to help with. Maybe a manjaro-arm specific plasma theme.
We use the Manjaro KDE theme (Breath2). But thanks.
