Known Issues and Solutions
This is a wiki post, please edit it when you find a solution to an issue you encountered
Mouse cursor is slow on Raspberry Pi
Due to a change in the Raspberry Pi kernels upstream, they no longer support FKMS. This can result in slow performance when using the FKMS drivers with the newer Raspberry Pi kernels.
Solution: Open /boot/config.txt, change fkms to kms in the dtoverlay line. Save the file and reboot.
Waydroid container cannot access internet
Cause: new default waydroid configuration issue, tracked here.
Short-term Solution:
- create
/etc/nftables.d/waydroid.nftwith the following contents:
#!/usr/sbin/nft -f
table inet filter {
chain input {
iifname "waydroid0" accept comment "Allow incoming network traffic from WayDroid"
}
chain forward {
iifname "waydroid0" accept comment "Allow outgoing network traffic from WayDroid"
ct state {established, related} counter accept comment "accept established connections"
}
}
- any time you launch waydroid, run the following after it has started:
echo "ip route add default via 192.168.250.1" |sudo waydroid shell
Old Issues
Plasma Dialer cannot answer calls
Sadly Plasma Dialer 22.02 has a serious regression with no known workaround. It’s not possible to accept incoming calls. Very sorry about this. Follow the upstream bug report. We will patch the package as soon as a solution is found.
Plasma Mobile - Black screen after update
We are seeing some reports about Plasma Mobile on the PinePhone only showing a black screen after entering the PIN after this update.
Workaround: Downgrade qt5-es2-wayland to 5.15.2+kde+r41 which is now back in Stable and Testing branch repositories.
New Breath theme not applying correctly
With the update to the new Breath theme, a migration package tries to apply the new theme correctly.
However this is not getting done for Plasma’s Lockscreen and the SDDM theme.
So please go through your settings after updating to make sure the themes are correctly applied.
Fix: manjaro-system should take care of this for you.
Plasma Mobile switch to ModemManager
With the PlaMo Gear 21.12 release, Plasma Mobile is now using ModemManager as the telephony stack. So in order to use SIM capabilities, you need to switch from using oFono to ModemManager.
Fix: Run sudo systemctl disable --now ofono ofonoctl && sudo systemctl enable --now ModemManager. You might have to reboot your phone for Plasma Mobile to pick up this change.
Plasma Mobile has does not launch after update
This was caused by an error in kwin 5.23.2 which only affects installs based on openGLES (qt5-es2).
Fix: Update to kwin 5.23.2-1.2 or above.
No ethernet on rk3399 boards
A recent kernel regression has resulted in built in ethernet on rk3399 based boards, such as RockPro64 and Rock Pi 4’s, no longer works on kernel 5.14. This is an upstream issue that has not been fixed yet.
Fix: Update to linux-5.14.1-2 or newer.
Vivaldi no longer working
The issue is present in all chrome based browser (except Chromium that got a patch for it).
It’s an issue with systemd-resolved and has been reported in the Arch Linux Bug Tracker.
Needs to be fixed by Vivaldi updates in the future.
Fix: Vivaldi 4.1.2369.21 fixed this issue.
Modemmanager-pp dependency issue
modemmanager-pp 1.16.10 depends on libqmi-pp and libmbim-pp, but they are no longer found in the repo.
Fixed by updated to modemmanager-pp 1.18rc1+2+ga20f2c05-2.
systemd-hook unsuccesful after pacman 6 update
After the pacman 6 update, updates will create this message in the post-transation hooks part:
Running the command manually works and there has been no issues reported as the result of this. This will either get fixed at some point in Pacman or SystemD.
Should be fixed with pacman-6.0.0-4
Keyring issues
If you have some gpg keyring issues, you can run sudo systemctl start pacman-init.service which will regenerate your keyring. Will take a few minutes to complete.
Should be fixed with manjaro-system-20210716-1
Plasma Mobile no longer boots
The current update to qt5-es2-base results in Plasma Mobile no longer booting, showing a screen that says to run a loginctl command to login.
Fixed by updating to qt5-es2-base-5.15.2+kde+r199-3.1 and qt5-es2-declarative-5.15.2+kde+r28-3.1.
Kwin crashes on startup on Pinebook Pro
This seems to be related to Mesa 20.3 and the Pinebook Pro support in kernel 5.10, as this does not seem to happen on other devices.
It does not impact 3d performance as far as I can tell. Just the OpenGL compositing in Kwin.
Fixed with mesa 20.3.2-2.
My VPN no longer connects
OpenVPN 2.5.0 changed how VPN routes work.
Workaround is to downgrade to previous version (2.4.9):
sudo pacman -U /var/cache/pacman/pkg/openvpn-2.4.9*
DP Alt Mode no longer works on Pinebook Pro
This is a known issue, the hacky patch we had to enable this has broken in recent kernels.
@tsys and Ayufan are looking into it.
As a workaround you can install linux-pinebookpro again.
FIXED with linux-5.9.12-4 and linux-rc-5.10-rc7-2 and above.
brcm-patchram-plus and pi-blueooth are in conflict
See this post for workaround:
[ARM Testing Update] 2020-11-16 - Bitwarden, Mesa-Git, Pacman and kernels - #10 by Darksky
Plasma Mobile Keyboard
The plasma mobile onscreen keyboard does not work with QT 5.15.0.
This is fixed by updating to kwin 5.19.3-1.1.
PinePhone uboot
This update to the PinePhone Uboot package (2020.04-2), changed how the DTS is loaded from the kernel, since the Kernel DTS for the Pinephone also changed. When doing this update on the PinePhone images from Alpha5 and back, please make this change to the /boot/extlinux/extlinux.conf before rebooting:
-
sun50i-a64-pinephone.dtbtosun50i-a64-pinephone-1.2.dtb -
root=LABEL=ROOTtoroot=LABEL=ROOT_MNJRO
Manual interventions:
The nss and zn_poly packages prior to version 3.51.1-1 and version 0.9.2-2 respectively, were missing a soname link each. This has been fixed in 3.51.1-1 and 0.9.2-2 of these packages, so the upgrade will need to overwrite the untracked files created by ldconfig. If you get any of these errors
nss: /usr/lib/p11-kit-trust.so exists in filesystem
zn_poly: /usr/lib/libzn_poly-0.9.so exists in filesystem
when updating, use
pacman -Syu --overwrite /usr/lib/p11-kit-trust.so --overwrite /usr/lib/libzn_poly-0.9.so
to perform the upgrade.
Device stopped booting after Uboot update
The uboot update included a change to the extlinux.conf file. This change will be incompatible with the old 1 partition layout of some devices.
So if you are updating installs made with images 20.02.1 or older, you need to apply this fix before rebooting!
To fix this please edit your /boot/extlinux/extlinux.conf file and add 2 periods in front of each first slash, like so:
KERNEL ../Image
FDT ../dtbs/ #etc.
APPEND initrd=../initramfs-linux.img #etc.
Save the file and reboot.
