You can switch drivers by running the GUI Additional Drivers from the Software and Update app.
Or you can do it from the terminal commandline by running these commands:
$ ubuntu-drivers devices
This will show you your available drivers. Then pick the nouveau driver found and switch to it with this command:
$ sudo apt install [xserver-xorg-video-nouveau]
The [xserver-xorg-video-nouveau] is an example a nouveau driver that might be found.
If for some reason you have removed your nouveau drivers, you can reinstall them with (for example):
$ sudo apt install nouveau-firmware
You can verify the available nouveau drivers from the repository with this command:
$ apt search nouveau

1I cannot find any explanation of what `nouveau-firmware` is needed for exactly. It is not listed among dependencies of `xserver-xorg-video-nouveau`, and selecting `xserver-xorg-video-nouveau` with GUI Driver Manager does not install `nouveau-firmware`. Could it be useful to install `nouveau-firmware` manually? Does the Nvidia card model matter? – Alexey Feb 16 '19 at 19:09

You may be right that the particular driver may not be needed. The command lines (which I edited the answer to clarify) are intended as examples for installing drivers. – L. D. James Feb 17 '19 at 09:33

When I try to install `xserver-xorg-video-nouveau` it says: The following packages have unmet dependencies: xserver-xorg-video-nouveau : Depends: xorg-video-abi-23 Depends: xserver-xorg-core (>= 2:1.18.99.901) – Lucas Bustamante Jul 02 '19 at 17:23

That means your library configuration is broken. There are quite a few Q&A's that addresses fixing **unmet dependencies** issues. This is a carefully filtered Google search of this site that may help you get started: https://www.google.com/search?ei=wcsbXc2ZNoK0gge4lpiYDg&q=%22ubuntu%22+how+to+resolve+video+unmet+dependencies+site%3Aaskubuntu.com&oq=%22ubuntu%22+how+to+resolve+video+unmet+dependencies+site%3Aaskubuntu.com&gs_l=psy-ab.3..0i71l8.0.0..307347...0.0..0.0.0.......0......gws-wiz.b9VnL4hfPcE The first one (currently) on the list will likely resolve your issue. – L.

Run
sudo apt purge nvidia-driver-390
sudo apt autoremove
and reboot.
Another way is to do it in "Software & Updates" -> Additional Drivers tab.

1I've tried that but then when rebooting it doesn't enter to desktop. – Smeterlink May 05 '18 at 11:02

2That may mean that your video card is not perfectly supported by nouveau. – Pilot6 May 05 '18 at 11:24

Answer my own question: ubuntu-drivers and "Software and Update > Additional drivers" are broken on ubuntu 18.04. We'll have to wait until developers fix it. For now just use the proprietary nvidia driver which works ok.

On Xubuntu 18.04, "Software and Update > Additional drivers" worked for me, but I had to replace the /etc/X11/xorg.conf file by the original one, /etc/X11/xorg.conf.nvidia-xconfig-original, which in my case is just a blank file.
