Hello,

After I updated the driver to 430.26, the monitor shows black screen with a blinking cursor.
I still can reach the computer over the network.

Above is the failing log ox Xorg

nvidia-installer.log (992 Bytes)

Did you install the non-GLVND GLX libraries? I can’t tell from your log because glxinfo is not installed and your installer log is from an install that was aborted because an X server was running.

If you did, please try reinstalling and selecting the GLVND libraries instead.

This is an error in the Ubuntu 16.04 packages, they’ve bundled the broken non-glvnd libs. See this how to fix it manually:

This did it! Thank you
