#### solution

安装cuda12.4

    wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
    sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
    wget https://developer.download.nvidia.com/compute/cuda/12.4.0/local_installers/cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
    sudo dpkg -i cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
    sudo cp /var/cuda-repo-ubuntu2204-12-4-local/cuda-*-keyring.gpg /usr/share/keyrings/
    sudo apt-get update
    sudo apt-get -y install cuda-toolkit-12-4

    解决方案 安装gst-plugins-libav 或者安装gst-plugins-meta 并打开USE=ffmpeg
    
        sudo emerge media-plugins/gst-plugins-libav

#### fcitx漏字

安装fcitx-gtk


<a id="org828deb3"></a>

### gnome


<a id="org3ccf1e1"></a>

#### 关于Gnome下wayland的问题

1.  nvidia

    首先安装nvidia驱动 然后rm /usr/lib/udev/rules.d/61-gdm.rules 然后在/etc/gdm/daemon.conf下WaylandEnable=true
    运行软件的时候
    
        __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia COMMAND

#### btd<sub>service</sub><sub>connect</sub>() a2dp-sink profile connect failed

bluetooth缺少pulseaudio支持 安装对应的包

    sudo pacman -S pulseaudio-bluetooth


## 编译问题
### ninjia
#### ninja: error: manifest 'build.ninja' still dirty after 100 tries, perhaps system time is not set
这是系统时间的问题 可以先将系统时间设置到未来 再使用ninjia编译
```shell
date -s "2077-06-11 15:30:00"
```
