Manjaro LXDE/LXQt on RPi4

[0n0w1c]

Picom helps with the desktop experience on the RPi4. I run it via autostart, with no effects, just to help with window tearing and laggy window movement.

/usr/bin/picom --config /dev/null --daemon --dbus --backend glx --log-level error

However, with kms, there is a blinking effect that seems to be driver related. fkms performs better, no blinking. However, it has an issue with blasting the Xorg.0.log file with pageflip error messages. So I created the following to disable pageflip:

$ sudo nano /etc/X11/xorg.conf.d/50-pageflip.conf

Section "Device"
    Identifier "vc4"
    Driver "modesetting"
    Option "kmsdev" "/dev/dri/card0"
    Option "PageFlip" "off"
EndSection

It does stop the spaming and seems to work well enough… except for watching videos. You will want to stop picom. Far too many dropped frames with it running. But the general desktop experience is improved.

Edit: I find that enabling Webrender in Firefox improves the dropped frame rate to an acceptable enough level, even with picom running.

LXQT is available in the Installer. But it’s a different setup, than the x86_64 one is. All of our editions are.

I found the ARM profile for LXQt easily enough and I am considering forking it. Is there a similar profile for x86_64, or is the use of profiles limited to ARM? Maybe x86_86 just uses a package list for the desktop installation on a minimal install? Unfortunately, it would seem LXQt finds little favor with the Manjaro users, or maybe there is a technical reason I am unaware of?

There is an x86_64 profile here.

Not that I know. I think it’s just not as popular, as it does not have it’s own window manager, but needs a third party one, like OpenBox.

hmm, i wonder how well lxqt would play with i3.
i currently have xfce4+i3, might have to give lxqt+i3 a try tomorrow.

i’m trying to grab lxqt but we’re having internet issues so it’s slow going.
let you know how lxqt+i3 go’s later.

[kerry_s]

it’s like 2 peas in a pod, so easy to set up.
i just need to fine tune things add a background app and it’s good to go.

okay my thoughts on lxqt+i3-wm.
it works & is easy to setup. lxqt widgets sucks when it come to system monitors.
opted to use i3status for decent system info.

[kerry_s]

off topic.
this little experiment got me thinking about raspberry os(standard 32bit) + i3-wm, the thing i hated the most in raspberry was window management, sure there’s a keyboard shortcut to move windows left or right, no drag to the sides.
anyways.
