为什么我的登录（用户名）页面上没有齿轮图标或齿轮登录按钮？

我有 Ubuntu 22.04.3 LTS、Gnome 42.9、窗口系统 X11。我尝试使用 Wayland，但我无法切换到它，因为我的登录（用户名）页面上没有齿轮图标或齿轮登录按钮。

我的设置：

/etc/gdm3/custom.conf：

这是否意味着我的GPU 与 Wayland 不兼容？ 我应该怎么办 ？

答案1

这确实意味着您当前的 GPU 与 Wayland 不兼容。NVidia 对 Wayland 的支持还很新，并且还不完整。

我应该怎么办 ？

继续使用 Xorg。

答案2

事实并非如此，答案是@钒完全是胡扯。楼主只是漏掉了gnome-session-flashback软件包。图标的存在/不存在怎么会与硬件组件相关？在主登录屏幕上甚至更多！拜托，我们不是在 iOS 上。
