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.

Get back the ability to free webcams/capture cards when not in active use

As of 4th of December 2023 OBS on Linux (v 30.0!!!) still has no way to disable v4l2 devices when those are not in active use.
The most baffling thing is that the patch was made by julijane almost four years ago. Insane, right?

Anyway, this patch is for OBS 30.0 (more specifically the master branch) and all it does is gets in Julijane's changes. Clone OBS, apply the patch via git and build. Onec done, you'll have that sweet "Disable when not showing" checkbox you love so much back.

In case you have no idea how to apply patches:

# Switch to the branch where the changes should be applied
$ git checkout master

# Apply the patch
$ git am bugfix.patch

# Check what has happened in the commit log
$ git log

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.

#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 GPU fan running at 50C by manually controling fans

  • install nvfancontrol
  • setup it in ./config/nvfancontrol.conf with "temp speed" values
  • add this thing to /home/USER/.config/autostart/ [Desktop Entry] Type=Application Name=NV fan control Comment=Enables windows-like GPU fan control. ~./config/nvfancontrol.conf has temp-speed settings. Exec=nvfancontrol Terminal=false Categories=System

fix telegram-desctop needing protobuf v25:

#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.

no scrollbar buttons anywhere!

fnid your theme in usr/share/themes and search for something like this in main.rc or main.css:

GtkScrollbar::has-backward-stepper = 1 (change value from 0 to 1)
GtkScrollbar::has-forward-stepper = 1 (change value from 0 to 1)

If you encounter any imports from a resource:// schema, go there in Thunar and search for "stepper" to know what to add.

On gtk2 it looks like described above. On gtk3 it looks like this:

* { -GtkScrollbar-has-backward-stepper: true; -GtkScrollbar-has-forward-stepper: true; }

Experiments are your friends now.

system-wide noise cancellation

install pulse-effects (pulse) or easyeffects (pipewire) This helped me: noise gate + RRNOISE + maximizer.json

Clicking scrollbar makes it jump there instead of page up/down

Edit (or create) the file:

~/.config/gtk-3.0/settings.ini

And add the following:

[Settings] gtk-primary-button-warps-slider = false
