图形部分设置 | 关于Ubuntu 20.04 中的 Wayland 下的页面让我感到困惑。
它声称我正在使用英特尔图形，而所有其他系统信息表明我正在使用英伟达图形。
当我登录 Wayland 会话时，图形部分显示：
Mesa 英特尔® UHD 显卡 620 (KBL GT2) / Mesa 英特尔® UHD 显卡...
但是，当我登录 XOrg 会话时，图形部分显示：
NVIDIA Corporation GP108M [GeForce MX150] / Mesa Intel® UHD Gra...
在 Wayland 和 XOrg 会话下，软件和更新应用程序始终显示：
使用来自 nvidia-driver-455 的 NVIDIA 驱动程序元包（专有，已测试）
Ubuntu Wayland 中的“设置”|“关于”页面上未列出 NVIDIA，这正常吗？
或者我忽略了什么？
为了确保 Nvidia 能够在 Wayland 中活跃，我采取了以下步骤：
使用以下方式安装 Nvidia 驱动程序：
ubuntu-drivers --gpgpu autoinstall nvidia在 GDM 上启用了 Wayland 选项
/etc/gdm3/custom.conf。grep "WaylandEnable" /etc/gdm3/custom.conf WaylandEnable=true删除了在 GDM 中使用 Nvidia 禁用 Wayland 的规则
/lib/udev/rules.d/61-gdm.rules。grep "DRIVER" /lib/udev/rules.d/61-gdm.rules # DRIVER=="nvidia", RUN+="/usr/lib/gdm3/gdm-disable-wayland"在 Grub 中将 Nouveau 列入黑名单
/etc/default/grub。grep GRUB_CMDLINE_LINUX_DEFAULT /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=nouveau"
如果有帮助的话，以下是显示图形信息的各种命令的输出。
