I did software update from the GUI pop-up notification - updated everything suggested except nvidia drivers (I had nvidia-375 installed, my GPU is nvidia Geforce 920M), and nvidia opencl libs.
After reboot it threw me that
The system is running in low graphics mode
So as I thought nvidia drivers should be also updated (to 378, or 384), because Xorg would require fresh nvidia libs - I did remove the current nvidia driver, then installed newer ones (378 then 384) but that didn't changed anything ...
Restarting lightdm not showing unity log-in gui, instead in the terminal I'm getting this:
No suitable _DSM call found
(also was getting this error during each boot with nvidia-settings and nvidia-prime installed, and was NOT getting when these packages are not installed)
As an additional info I have a nouveau driver blacklisted as so in /etc/modprobe.d/blacklist.conf
blacklist nouveau
Also in the Xorg.0.log I can see the following
Fatal server error:
[26.673] (EE) no screens found(EE)
Is this issue related to lightdm???
What's the root of the problem?
How to fix this?
