[Panic] Create softbuffer surface for window: PlatformError(Some("Visual 0xb3 does not use softbuffer's pixel format and is unsupported"), None)

[Hoerli1337]

Hi!
I have installed the application according to the instructions.

1. sudo apt install lm-sensors

wget https://raw.githubusercontent.com/wiiznokes/fan-control/master/resource/linux/60-fan-control.rules
sudo mv 60-fan-control.rules /usr/lib/udev/rules.d
sudo udevadm control --reload-rules && sudo udevadm trigger

3. Install over Application management
4. Start fan-control >> Nothing :(

Running all in a terminal:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=fan-control io.github.wiiznokes.fan-control

Hi,
the panic indicate that the renderer doesn't support your display apparently. I don't really know much in this but maybe it could be fixed with wayland, a fix in softbuffer, or switching to wgpu. But wgpu is currently deactivate because it cause seg fault on flatpak.

The other errors probably indicate that the udev rules doesn't works.

If you really want to use fan-control now, you can try this (with no UI):

# change 7 with the right number (depend on the PC)
sudo chmod -R a+w /sys/class/hwmon/hwmon7
flatpak run io.github.wiiznokes.fan-control --cli

[Hoerli1337]

Thanks for the info.
At the moment I can still make do with LibreFan.
The project was just discontinued, so I wanted to give fan-control a try.

Hopefully you will get it fixed :)

I ran into the exact same problem (minus the sensor errors). Following the same installation steps as noted by the first user and resulting in the same error.

This is very unfortunate, there are already 3 users that reported this issue. I made an issue here FYI: rust-windowing/softbuffer#215

[wiiznokes]

@yggdrasil75, @Hoerli1337, @darkraisisi , @miguelccoelho

Hi, sorry for the notif, a question was asked in the related issue: rust-windowing/softbuffer#215

@wiiznokes Can you please share the output of xdpyinfo on the affected system?

Please subscribe to it in the future if you want as i can't provide information

This is somewhat strange, as I don't see 0xb3 in this list. It looks like somehow the visual 0xb3 is being passed into softbuffer... which it rejects because it doesn't exist.

Can you run xtrace with the failing application and post the logs?

[darkraisisi]

I tried running xtrace but i honestly don't know if this error is related or not. Please inform me on how to do it properly if need be, rtfm didn't help me.

xtrace /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=fan-control io.github.wiiznokes.fan-control

also running the cli version askes for a config file, where can i find this?
flatpak run io.github.wiiznokes.fan-control --cli There is no active configuration defined You can define one in /home/popper/.var/app/io.github.wiiznokes.fan-control/config/fan-control directory, Or specifie a config to use using an argument

[wiiznokes]

also running the cli version askes for a config file, where can i find this?

The are example in this directory. I plan to add some doc for it some day. Don't forget to change current_config in settings.toml, or point to it via command line (see the --help option).

Please, open another issue if you have further questions

[wiiznokes]

@notgull I also get this bug with x11

[Vaaarna]

same issue, i will blow my brains bc fan is right by my face and has no chill (statement for comedic effect and to add a +1 to the issue, i am chilling and wish yall a good day)

[wiiznokes]

hi all, i've just pushed an update on flathub, with the wgpu feature activated. This should solve this issue for most of you.

Edit: the udev rules have also been updated latelly, so make sure you reinstall them for better compatibility

[zhangjing-GitHub-Code]

Well, On my Arch Linux x86_64, when I login KDE6 with X11, it has this error, but the app starts when I use Wayland.
Wiiznokes, are you using x11 or wayland?

[wiiznokes]

The bug is only present on x11. But now that wgpu is active, if you have a GPU, you should not be affected
