我有一台配备i7-8750H和Nvidia Quadro P2000 GPU（以及英特尔集成显卡）的Dell Mobile Precision 7530笔记本电脑。操作系统是Ubuntu 18.04（操作系统和GPU由Dell一起安装）。
sudo apt-get install nvidia-driver-440
the laptop, on boot-up, just shows a black screen with the message "Started bpfilter". I can still access the command line with ctrl-alt-F1; if I do this and uninstall the drivers with
sudo apt-get remove --purge nvidia-* the computer is able to boot up normally. I used nvidia-driver-440 because this was listed as recommended in
ubuntu-drivers devices but I've also tried 390 and gotten the same issue.
我也无法在此笔记本电脑上使用外接显示器，我认为这是一个相关问题。在未安装Nvidia驱动程序的情况下，如果我通过HDMI插入外接显示器，则无法识别。如果随后打开系统设置，则桌面会变黑，并显示相同的“ Started bpfilter”消息。如果然后拔下监视器的电源，则会被踢出Ubuntu登录屏幕。
- Tried modifying /lib/modprobe.d/nvidia-kms.conf as described in this post on the Dell Community forums. Did not seem to have any effect.
- Installed driver using the .run file from the Nvidia website. Gave the same "Started bpfilter" hang.
- As recommended in this post, I tried modifying /etc/gdm3/custom.conf, and tried the lightdm, gdm3, and slim display managers. Lightdm gives me the same result. slim gives a black screen on boot-up (no "Started bpfilter" message). With gdm3 activated, (and with the "WaylandEnable=false" line in /etc/gdm3/custom.conf commented out), I am able to get to the log-in screen with the Nvidia driver installed. However, I cannot log in - after entering my password I get sent back to the log-in screen.
