Touchbar stops working after reboot

[Rom888]

After this command it starts working: sudo touchbar --restart

$ journalctl --boot=0 | grep tiny-dfr

Does running sudo touchbar --restart turn it on?

[Rom888]

Yes

[AdityaGarg8]

Run this whole command:

sudo touchbar --restart

[AdityaGarg8]

Then see if this is fixed or not

[Rom888]

It worked after the first reboot, but didn't work after the second.

[AdityaGarg8]

again, is is working if you run sudo tiny-dfr after second reboot?

[Rom888]

sudo tiny-dfr or sudo touchbar --restart ?

[AdityaGarg8]

Either works

[AdityaGarg8]

If yes, then try this. Note that it would delay the turning on of touchbar by 7 seconds, so be a bit patient.

sudo touchbar --restart

[Rom888]

no, doesn't work after: sudo touchbar --restart

[AdityaGarg8]

what does sudo tiny-dfr show.

[Rom888]

if I run sudo tiny-dfr touchbar stars working but I don't get control back in the terminal, no response

[AdityaGarg8]

ctrl+c to get control of terminal (this will turn off the touchbar). And run the command I sent which delayed it by 7 seconds

[AdityaGarg8]

After running that command, restart.

[Rom888]

it doesn't work after reboot

[lemmyg]

Has stop working after Ubuntu pkg update. Did you try to remove the config in /etc/tiny-drf.conf and reinstall the pkg?

[AdityaGarg8]

if you do this:

Run sudo systemctl disable --now tiny-dfr

Then restart. The touchbar won't turn on after restart.

Then run sudo systemctl enable --now tiny-dfr and wait for 10 sec, does touchbar turn on?

[Rom888]

Did you try to remove the config in /etc/tiny-drf.conf and reinstall the pkg?

No

[lemmyg]

Try to remove and reinstall

[AdityaGarg8]

make sure you remove /etc/tiny-dfr.conf.orj before you reinstall

sudo rm /etc/tiny-dfr.conf.orj
sudo apt remove tiny-dfr
sudo apt autoremove
sudo apt update
sudo apt install tiny-dfr

[Rom888]

I don't have /etc/tiny-dfr.conf.orj only /etc/tiny-dfr.conf

[Rom888]

Reinstalled, touchbar starts working then ran sudo systemctl disable --now tiny-dfr then restarted, but the touchbar turned on after restart.

[AdityaGarg8]

So your problem is fixed now.

[Rom888]

I reconfigured it using touchbar --mode and after that it doesn't work

$ sudo tiny-dfr
thread 'main' panicked at src/main.rs:620:53:
called `Result::unwrap()` on an `Err` value: TOML parse error at line 11, column 23

[alex-007]

I see that in the /etc/tiny-dfr.conf the headers of the section doesn't close ']'

[time]
use_24_hr = 1

[layers.primary_layer = "specialextended"
buttons = [
    { label = "F1", key = "Key::F1", mode = "text" },
...

[alex-007]

BTW reverting back to tiny-dfr to 0.1.3-5 and sudo cp /etc/tiny-dfr.conf.orj /etc/tiny-dfr.conf restores the touchbar after reboot

[alex-007]

OK. I found the following:

1. when you install the new tiny-dfr, it puts the new config which is OK
2. you can change it manually and it immediately shows the changes in the touchbar (I changed the layers.tertiary2_layer_buttons to show F7-F12 buttons for the debugging my applications and it worked)
3. But when you try to modify the config with help of touchbar (like sudo touchbar --mode) it ruins the config. First 2 sections received the names [layers.primary_layer = "specialextended" and [layers.secondary_layer = "function" (no closing brackets ']')

[alex-007]

I couldn't find where to put patch for touchbar. So here it is to fix the issue

'touchbar --mode' works now

Let's try this. In case the touchbar is not able to start on boot, it waits for 5 sec and starts it again, and in total makes 5 such attempts. So wait for a min after restarting.

You are using an LTS kernel, tiny-dfr won't work on that. Remove it by running sudo apt remove tiny-dfr

After removing, boot into macOS and then back to linux
