mx23 respin for Raspberry Pi 5, systray brightness.
Posted: Sat Jun 22, 2024 11:29 am
by susan707
I've been running mx23.1 respin for arm on a Raspberry Pi5 for quite a few months, I installed PyCharm, GDLauncher for Minecraft and loads of other stuff, it's amazing.
But since I installed mx 23.1 on the Pi the brightness systray control for the screen does nothing, the menu comes up but the adjustments do nothing and I recently tried downloading mx23.3 hoping the issue was fixed but it's not.
Can anyone tell me how to fix this as I would love to be able to start rhythmbox and the radio at night and then dim the screen right down, any help would be very welcome thanks.

Hi --
I was going to ask you to post on the Forum when I wrote my YT comment this morning but forgot. I'm glad you have posted because I tested later and can confirm that the Brightness Systray appears to have no effect on the Pi 5 (haven't tried the Pi 4 yet). @dolphin_oracle

That's good, thanks for looking at it @Jerry3904, lets hope someone has already solved this as it's a really handy adjustment to have on any system.

I would have thought the software brightness part would work. But the hardware backlight probably wouldn’t unless the display had an accessible interface. Most external devices do not.

@dolphin_oracle The display is HDMI 24" XG24IPS gaming monitor.
So when you say "But the hardware backlight probably wouldn’t unless the display had an accessible interface. Most external devices do not" are you saying that the brightness systray makes adjustments via the monitor's backlight?

I’m not near a pc but it’s likely there is no accessible external interface for the hardware backlight. Or at least not one the brightness tool can use.

@dolphin_oracle Forgive me, but I'm not sure what you are talking about exactly, for example if I create an image jpg whatever, and it's totally black, and I display it full screen, the screen effectively goes dark, but I can see that the backlight is still working if I'm sitting in the dark.
So I'm not entirely sure what you mean, do you know if the brightness systray works via controlling the backlight?
So I just tried using the brightness systray from MX tweaks on another computer that I'm running MX23 on and it works fine, when I turn the brightness down to 0, I can tell that the backlight is still working but whether it's at full brightness I can't say.

There are two functions. The backlight control and a software control that affects how the x server displays brightness. The software one I would think would work. The backlight one probably not.

Thanks @Jerry3904 for your attention to this problem, I read the post on Raspberry Pi forum, Wayland on Raspberry Pi OS etc.
I'm going to wait until someone sorts this problem out for the MX 23 respin, until then it's a piece of cardboard covering the front of the monitor held there by magnets.

OK, Susan. I would like to point out that that RPi Forum thread seems to make clear that the problem is not limited to MX-Linux or perhaps even to the Pi 5, but is inherent to RPi itself. We'll try to chase this down.

To add a data point: I tested this tool on the Official Display that runs on a Pi 4b. It had no effect on either the Buster or the Bookworm version.

i went commandline and that didn't work either. the xrandr software Brightness value was saved and set to the X session, but has no effect. Its either the way the X server is compiled or the display driver, I don't know which. Given the pi's unique graphics hardware, I tend to think target the display driver, and I'm not sure how motivated the pi folks will be to change the situation.
since all displays on the pi are external, I would be very surprised if the backlight function worked at all.

command is correct, its just not utilized.
given the target for pi devices, mostly being headless, I imagine it was totally left out of the display driver. I really don't know how all this works, but the display brightness was set.
you could try messing with gamma, which is old school but is at least a different path.

OK. I've looked at a bunch of web suggestions and at various "backlight" packages in Synaptic, but the big problem I see is that there is nothing in /sys/class/backlight/ to manipulate. I do see some 70 pkgs in a Thunar search on "backlight" but nothing I would ever know to mess with.

that's what I'm saying, its very rare you can manipulate the backlight of an external device. I think some displayport monitors can do this, but mostly no. an external monitor should have its own controls though. (don't know if the little official or kit style monitors would though).

Thanks, I wasn't getting that.
I conclude that there is a reason that RPi has no app for this...
