独立显卡装上后怎么黑屏啊???急,独立显卡安装好了但是电脑开机黑屏

LightDM

For the LightDM display manager:

/etc/lightdm/display_setup.sh #!/bin/shxrandr --setprovideroutputsource modesetting NVIDIA-0xrandr --auto

Make the script executable:

# chmod +x /etc/lightdm/display_setup.sh

Now configure lightdm to run the script by editing the [Seat:*] section in/etc/lightdm/lightdm.conf:

/etc/lightdm/lightdm.conf [Seat:*]display-setup-script=/etc/lightdm/display_setup.sh

Now reboot and your display manager should start.
