#### Default browser
[https://askubuntu.com/a/1076085/1085672]( https://askubuntu.com/a/1076085/1085672)

```
mkdir -p /usr/local/portage

```
add `PORTDIR_OVERLAY=/usr/local/portage` to `/etc/portage/make.conf`
- The folder structure in your overlay folder should be the same as found in /usr/portage so if you wanted to make an ebuild for a theme you would put that in /usr/local/portage/x11-themes.
```
// copy files to /usr/local/portage/CATEGORY_FOLDER/PACKAGE_NAME_FOLDER/PACKAGE.ebuild

# ebuild /usr/local/portage/CATEGORY_FOLDER/PACKAGE_NAME_FOLDER/PACKAGE.ebuild digest

#### Installing electron apps (example with Min)
```
sudo emerge -q nodejs && sudo npm install -g npm
npm install && npm run build && npm exec electron-packager . && sudo sh -c 'mv ./Min-linux-x64 /opt && ln -s /opt/Min-linux-x64/Min /usr/bin/min'

#### delete partition after mkfs
[https://superuser.com/a/1281363/1258400](https://superuser.com/a/1281363/1258400) [https://linux.die.net/man/8/wipefs](https://linux.die.net/man/8/wipefs)

#### Failed to load /dev/dri/card0
[https://forums.funtoo.org/topic/2904-failed-to-load-devdricard0/?do=findComment&comment=12821](https://forums.funtoo.org/topic/2904-failed-to-load-devdricard0/?do=findComment&comment=12821)
- get rid of the nomodeset in /etc/boot.conf      re-run `ego boot update` and reboot

#### grub2-install: "this GPT partition label contains no BIOS Boot Partition"
[https://superuser.com/a/1610045/1258400](https://superuser.com/a/1610045/1258400)
- You already have this tiny partition, so kk the first partition starts not with 1 but with 2048

```
/dev / sda1 2048 411647 409600 200M Linux file system (/boot)
```
You need to change the label type, from boot to bios_grub for example through parted:
```
parted /dev/sda
set 1 boot off
set 1 bios_grub on
q
```
Then again:
```
grub2-install /dev/sda
```

#### Audacious fix
- write (to turn on the arch)
  ```
  media-sound/audacious **
  media-plugins/audacious-plugins **
  ```
  into /etc/portage/package.accept_keywords/audacious
- add the gentoo_ice-wmms line from [https://gitweb.gentoo.org/repo/gentoo.git/tree/media-sound/audacious/Manifest](https://gitweb.gentoo.org/repo/gentoo.git/tree/media-sound/audacious/Manifest) into `/var/git/meta-repo/kits/media-kit/media-sound/audacious/Manifest`

> Test it with echo "$DBUS_SESSION_BUS_ADDRESS". If you get a directory as output, then you have a dbus session id for these programs to use.

        subject.isInGroup("power")) {
        return polkit.Result.YES;
    }
});
```

#### ElectronMail "No native build was found"
Package the app, even if you can't do it all the way. So just run
```
npm run electron-builder:dist:linux:rpm
```
even if it gives an error, the app should be working. To test, do `npm run start:electron`

#### clang undefined reference to `setupterm' ninja -v -j4 -l0 distribution failed
[https://github.com/dougpuob/cppnamelint/issues/24](https://github.com/dougpuob/cppnamelint/issues/24)
Rebuild llvm without ncurses flag

### circular dependencies
[https://forums.gentoo.org/viewtopic-t-1078738-start-0.html](https://forums.gentoo.org/viewtopic-t-1078738-start-0.html)
Try to emerge each one with `--nodeps`.

### piper and ratbagctl can't connect to ratbagd
[https://github.com/libratbag/piper/issues/559#issue-677712902](https://github.com/libratbag/piper/issues/559#issue-677712902)
`sudo usermod -aG games USERNAME` and reboot (logout is not enough!).

### libreoffice --draw and --impress show "loading component library libsdlo.so failed"
[https://bugs.funtoo.org/browse/FL-8035](https://bugs.funtoo.org/browse/FL-8035)
Emerge `app-office/libreoffice-bin` with the `zeroconf` flag. Potentially beforehand do `emerge -C app-office/libreoffice-bin && rm -rf /usr/lib64/libreoffice/`.
If that doesn't work, try installing libavahi. Draw doesn't use it and Impress uses it for Remote Control.

[https://forum.slitaz.org/topic/libreoffice-problems-libsdloso](https://forum.slitaz.org/topic/libreoffice-problems-libsdloso)

Only if **both** fail, you could try making a "blank" libavahi:
```
echo 'int avahi_client_new(void) { return 0; }' > libavahi-client.c
echo 'int avahi_threaded_poll_new(void) { return 0; }' > libavahi-common.c
gcc -c libavahi-client.c libavahi-common.c
gcc -shared -o libavahi-client.so.3 libavahi-client.o
gcc -shared -o libavahi-common.so.3 libavahi-common.o
cp libavahi-*.so.3 /usr/lib64/libreoffice/program/
```
