After installing the latest NVidia proprietary driver (version 390) using Software & Updates > Additional Drivers, it wasn't possible to change the backlight intensity/brightness of the screen.

The solution that worked for me was to run: sudo setpci -H1 -s 00:01.00 BRIDGE_CONTROL=0. If that solution works for you too, then you may want to make the change permanent. Otherwise, you will have to run the same command each time you power on your Macbook.

Steps to make the change permanent:

1. Open "Terminal"
2. Run sudo gedit /etc/rc.local
3. Enter:

1. Open qjackctl
2. Click Setup...
3. Choose "alsa" as the Driver
4. Choose the analog interface as the Interface (in my case it is hw:PCH,0)
5. Go to the Advanced tab
6. Enter the number of inputs in the first textbox next to Channels I/O (2 in my case)
7. Enter the number of outputs in the second textbox next to Channels I/O (2 in my case)
8. Click OK
9. Click Start
10. Start Bitwig and select "JACK" as the Driver model

If you need/want to generate an AppImage for Bitwig on a non-Debian Linux:

1. Download or clone https://github.com/AppImage/pkg2appimage
2. If you don't have Docker installed, install it
3. Start Docker
4. Run ./pkg2appimage-with-docker recipes/Bitwig-Studio.yml (for some reason AppImage already has a recipe for Bitwig)
5. If it fails, and asks you to set the environment variable ARCH: add the line ENV ARCH=x86_64 (or your architecture) to ./Dockerfile, below DOCKER_BUILD=1

Just in case it's not clear: you have to follow the steps on a terminal, at least step 4.

Solution to copy & paste on the Terminal

flatpak override --user --env=PROTON_NO_ESYNC=1 com.valvesoftware.Steam

Explanation

I tried to play World of Warships on Clear Linux using the flatpak of Steam, but the game never started. So, I ran flatpak run com.valvesoftware.Steam on the Terminal to see if there was any useful information. The error that called my attention was eventfd: Too many open files. I did a google search and found some mention about setting PROTON_NO_ESYNC=1 as an environment variable. So, I ran flatpak override --user --env=PROTON_NO_ESYNC=1 com.valvesoftware.Steam on the Terminal, to set the environment variable PROTON_NO_ESYNC=1 for com.valvesoftware.Steam. I tried again and it worked.

I needed to use a TextInput in a CreateView for a ManyToManyField and I couldn't find a simple good solution. After looking through the Django source code I noticed that value_from_datadict() is used for ManyToManyField inputs.

In the forms.py file you need something like:

from django.forms import ModelForm, TextInput
from .models import Product

class ManyToManyInput(TextInput):
  def value_from_datadict(self, data, files, name):
 value = data.get(name)
