Frequently Asked Questions - Ubuntu and it derivatives (e.g. Linux Mint)

A) How do I Install Envy?

1) Download and install the deb package:

double click on the deb package in Ubuntu (or Xubuntu) OR open Terminal or Konsole and type:

cd path_to_envy's_deb_package

sudo dpkg -i envy*.deb

2) Enable Ubuntu's "universe" and "multiverse" repositories. See Point E of this page.

3) Make sure that all the dependencies were installed by typing:

sudo apt-get install -f

NOTE: if the dependencies cannot be installed you will have to enable

4) Launch Envy's GUI (inside a Desktop Environment such as GNOME,KDE, etc.) by selecting it in the "Applications/System Tools" menu

OR if you need to use Envy's textual interface you will have to type:

sudo envy -t

B) Can I use Envy 0.9.x if I had installed the Nvidia driver via Envy version 0.8.2 (or lower) or via the Nvidia installer?

Yes, you can, but you will need to follow these steps:

1) Remove the older version of envy (you can skip this step if you only used the Nvidia installer):

sudo aptitude purge envy

2) Download and install Envy's deb package

3) Log out and press CTRL+ALT+F1 (so as to get out of the Desktop Environment, i.e. you'll see ONLY the command line)

4) Log in (if required)

5) Run Envy's textual installer by typing:

sudo envy -t

6) Choose to "Clean the Installation of any Nvidia driver" by typing "6" and press ENTER.

WARNING: if "Envy" seems to hang on Ubuntu's splash screen you will have to press Alt+F1. (this usually happens on Kubuntu)

7) Then you can use the "Install" function.

NOTE: you will NOT need to repeat the whole process next time you want to install the Nvidia driver (you should be able to use Envy's GUI)

C) What happens if you are no longer able to access your Desktop Environment (because of a blank screen at boot)?

Boot in RECOVERY MODE from the GRUB Menu (select it using your keyboard) almost as soon as you turn on your computer (it will take you to the command line).

Then you will need to type:

envy --uninstall-all

then simply type:


and boot as usual.

On next reboot the Xserver should work fine (but you will use the open source driver)

D) What happens if I upgrade Ubuntu to a newer release (e.g. from Ubuntu Edgy to Ubuntu Feisty)?

You will only have to follow these steps:

1) Launch Envy and use the "Uninstall" function to uninstall the Nvidia or the ATI driver

2) Uninstall the Envy from Synaptic/Adept or from the command line

3) Set the driver back to either "nv" ( instead of "nvidia", if you use a Nvidia card) or "ati" ( instead of "fglrx", if you use an ATI card) in the Section Device of your /etc/X11/xorg.conf which you can edit by typing:

sudo nano -w /etc/X11/xorg.conf

NOTE: press CTRL+X to exit (save the file)

4) Log out and press CTRL+ALT+Backspace (so as to restart the Xserver)

5) Log in and upgrade your Ubuntu installation

NOTE: if the Xserver crashes you will have to use "vesa" instead of "ati" or "nv"

E) What shall I do to enable the required repositories on Ubuntu?

You will have to enable Ubuntu's "universe" and "multiverse" repositories.

Have a look at this page to see how you can do it (read where it says Enabling Extra Repositories on that page): Enabling Extra Repositories

F) What happens if the kernel is upgraded (e.g. via system updates)?

You will only have to follow these steps:

1) Restart your computer and the Xserver will crash (since it will lack a module).

Say No if the system asks you whether you want to see the output of the error to debug.

NOTE: press ALT+F1 if all you can see is a black screen

Then launch Envy's textual interface from the command line by typing:

(if you're using Ubuntu)

sudo envy -t

(OR, if you're using Debian)

su -c "envy -t"

G) Shall I uninstall the ATI/NVIDIA driver before I install a new version of the driver through Envy?

Envy will do it for you. However if you want to uninstall the driver, nothing bad will happen ;)

Known Issues

Envy cannot be launched from the Applications menu on Debian Etch unless you add your username to the sudoers list

You can launch Envy by typing:

envy -g
