Desktop background goes black after a screen lock

Post by shambam » Wed May 30, 2018 7:30 am

Just as the title says. I have a fresh install of 18.3, but every time my screen locks and I pword back in, the desktop background pic is gone and is just black. If I try go into the settings nothing works, clicking on any background choice makes no difference, it still remains black. Rebooting will bring the wallpaper back until the first screen lock.

Any help appreciated.

Hello again,
You have Nvidia graphics card but no Nvidia driver installed. This is what I would try first go to update manager and then the view tab, then kernels.
install the latest 4.15 kernel reboot and go to driver manager under Administration in the Menu and install the recommended Nvidia driver for you card.
if that does not fix the problem, you'll need to install a newer Nvidia driver than mint offers. Let us know and well tell you how to do that.
Do you know which Nvidia card is installed in the machine?
Please also list the out put of

Code: Select all

 lspci | grep VGA

This is strange because after installing the OS I opened the driver manager and selected the nvidia-381 driver which *apparently* it is using now. The card is a GTX1080. Should this not work or should I go ahead and update the kernel?

I'm afraid that the 1080 card is a problem in Linux but it can be overcome.
here is a page that tells you how to install cuda and proper driver for you card. It's technical so you'll need to take your time and digest what it is saying.
but it should do away with the black screens when you fininshed. good Luck
