# build obs from source
Install:
linux-headers (I have linux61-headers-6.1.60-1)
v4l2loopback-dkms (v4l2loopback-dkms-0.12.7-2 for me)
ninja cmake curl ccache zsh qrcodegencpp-cmake hiredis pkgconf libdatachannel libjuice rav1e-git dav1d-git decklink

Download and unpack CEF (for browse source) + clone and build obs in portable mode:
clear && cd "$HOME" && rm -rf "$HOME/portable_obs_build_dir" && mkdir -p "$HOME/portable_obs_build_dir/" && cd "$HOME/portable_obs_build_dir" && wget https://cdn-fastly.obsproject.com/downloads/cef_binary_5060_linux64.tar.bz2 && tar -xjf ./cef_binary_5060_linux64.tar.bz2 && git clone https://github.com/obsproject/obs-studio --recursive && cd obs-studio && rm -rf build && rm -rf "$HOME/.config/obs-studio" && rm -rf "$HOME/portable_obs_build_dir/release" && mkdir build && cd build && cmake -DLINUX_PORTABLE=ON -DCMAKE_INSTALL_PREFIX="$HOME/portable_obs_build_dir/release/" -DENABLE_BROWSER=ON -DCEF_ROOT_DIR="../../cef_binary_5060_linux64" -DENABLE_AJA=ON -DTWITCH_HASH=0 -DTWITCH_CLIENTID=selj7uigdty0j5ijt41glcce29ehb4 -DOAUTH_BASE_URL=https://auth.obsproject.com/ -DENABLE_BROWSER_PANELS=ON -DENABLE_DECKLINK=ON -DENABLE_FREETYPE=ON -DENABLE_HEVC=ON -DENABLE_JACK=ON -DENABLE_LIBFDK=ON -DENABLE_NEW_MPEGTS_OUTPUT=ON -DENABLE_PIPEWIRE=ON -DENABLE_PLUGINS=ON -DENABLE_PULSEAUDIO=ON -DENABLE_QSV11=ON -DENABLE_RNNOISE=ON -DENABLE_SCRIPTING=ON -DENABLE_SCRIPTING_LUA=ON -DENABLE_SCRIPTING_PYTHON=ON -DENABLE_SERVICE_UPDATES=ON -DENABLE_SNDIO=ON -DENABLE_SPEEXDSP=ON -DENABLE_UI=ON -DENABLE_V4L2=ON -DENABLE_VLC=ON -DENABLE_VST=ON -DENABLE_WAYLAND=ON -DENABLE_VST_BUNDLED_HEADERS=ON -DENABLE_WEBRTC=ON -DENABLE_WEBSOCKET=ON -DBUILD_TESTS:BOOL="1" -DENABLE_JACK:BOOL="1" -DENABLE_SNDIO:BOOL="1" -DENABLE_RTMPS:STRING="ON" -DCMAKE_BUILD_TYPE:STRING="RelWithDebugInfo" -DCALM_DEPRECATION:BOOL="1" -DENABLE_LIBFDK:BOOL="1" -DENABLE_UDEV=ON .. && make -j12 && make install && cd "$HOME/portable_obs_build_dir/release/bin/64bit/" && ./obs

Remove libva-vdpau-driver (segfaults obs on load don't know why):
sudo pamac remove libva-vdpau-driver

In the end rav1e-git and dav1d-git will probably complain about ffmpeg depending on them, but all three work just fine.
I've used a combination of pacman, pamac and pamac GUI to install all the needed things, cause none seect one would onlieg and do what I wanted it to do. 


# remove flatpak support
removing flatpaks from manjaro be like:

$ flatpak list

Remove a named app
$ flatpak uninstall io.lbry.lbry-app

Uninstall unused flatpaks
$ flatpak uninstall --unused

Uninstalling apps may not remove everything - so how much is left?
du -ch /var/lib/flatpak

If the total is more than a few MB you may want to cleanup leftovers
sudo flatpak repair

Disable flatpak support
$ sudo nano /etc/pamac.conf

Modify the last lines to look like below and save the changes (you will also find snap support) but as this is about flatpak leave as is.
  #CheckFlatpakUpdates
  #EnableFlatpak

Then remove flatpak packages using pacman
$ sudo pacman -Rns flatpak libpamac-flatpak-plugin

Then update your system
$ sudo pacman -Syu

Finally restart your system

# fix rust
failed to create directory `/.cargo/registry/cache/index.crates.io-6f17d22bba15001f`
means don't do it under root, stupid!
create the folder ~./cargo and use sudo on whichever command you're trying to issue.
If you're inside sudo mc - it'll freak out like that, demanding a place in / #oof

#fix bright as shit pamac-gui
install pamak-gtk3, that uses gtk3 themes 


# windirtree replacement
qdirtree

# fix brightness/contrast:
make ~.nvidia-settings-rc read-only

# fix stuttering in games:
- get mangohud and goverlay
- in goverlay:
    - disable vsync
    - set framecap to match your monitor

#nvidia led 
install that shit if you have nvidia LOGO on your GPU.
Else hope that OpenRGB works.
Their support is meh at best, tho

sudo make install


# No object for D-Bus interface

NTFS partitions can be that way even with no errors on them

`systemctl --user restart gvfs-udisks2-volume-monitor`

Also, 
- First, go to Dash (for Ubuntu) or run gparted using superuser, preferrably gparted-pkexec.
- Right click the partition, choose New UUID.
- Click the Apply button.

Update: Some people claimed that just by having gparted refreshing information, the problems are solved. You should try that first, as refreshing UUID screws up fstab.
