sddm 仅显示黑屏

我是 Arch Linux 的新手，想将 Plasma 5 桌面与 sddm 一起使用。
我可以startx毫无问题地启动等离子桌面，但是当我尝试使用 sddm 时，它只在启动时显示黑屏。

我尝试重新启动 sddm 服务，systemctl restart sddm但它仍然是黑色的。

当我运行时，sddm-greeter --test-mode --theme /usr/share/sddm/themes/breeze它显示欢迎屏幕，但我无法让它在启动时运行。

我的/etc/sddm.config看起来像这样：

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=
RebootCommand=

[Theme]
Current=breeze
CursorTheme=breeze_cursors

[Users]
MaximumUid=65000
MinimumUid=1000

并journalctl -b --unit=sddm.service给我以下输出

答案1

我不知道为什么 Elmo Todurov 写了评论而不是答案，但这确实是我唯一可行的解​​决方案，因此也是一个答案。

编辑文件：/usr/share/sddm/scripts/Xsetup

添加以下行：

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
