#### 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

#### fcitx漏字

安装fcitx-gtk


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

#### 很多软件无法fcitx键入
指定环境变量启动
```shell
QT_IM_MODULE="fcitx" GTK_IM_MODULE="fcitx" XMODIFIERS="@im=fcitx" command
```
### 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
