Live systems and NVIDIA graphics cards - Live systems and NVIDIA graphics cards - TUXEDO Computers

In general, NVIDIA graphics cards work directly with the Ubuntu live system without any intervention. Sometimes it may be necessary to enable the nomodeset option to boot the live ISO.

Before installation

You can do this already before the installation, the setting will be taken over into a completely installed Ubuntu system.

1. Boot the live system from the USB stick or DVD.

2. Select the second point for installation in the boot menu with the down arrow keys and press "e" to edit.

3. Move the cursor with the arrow keys to the line linux /casper/... as well. and then to the end of the line after splash --- and the space at the end.

4. Now add   nomodeset   to the line. A line break, if necessary, will be generated automatically and marked with a \ sign. (On some distributions you have to add   nvidia.modeset=0   instead of   nomodeset   )

5. Press F10 to save the changes in one step and boot the system.

Before installation without UEFI

1. Boot the live system from the stick or from the DVD.
By pressing any key on the start screen (small logo in the middle at the bottom) you reach a selection screen, which first opens a menu for language selection. Select your preferred language and confirm with Enter.

2. Press the F6 key to open a selection menu with frequently used boot options. These can be selected using the arrow keys and activated with Enter. Activated options are marked with a small "X".

3. Close the menu again directly without making any changes with Esc. A line with kernel calls is now displayed below the main menu, which you can change and extend manually.
Within the line you move the cursor with the arrow keys left and right. If new options are entered before the two hyphens (--) at the end of the given line, only the live system is started with these options.
To take over the options for a system installed with the Live-CD, enter them behind it.
Important: All options - including the hyphens - must be separated by a space.

4. There is already a space at the end of the line. So enter the option nomodeset after the two hyphens.

5. The system is started with the now adapted kernel call finally with Enter.

In an already installed system

To specify the option nomodeset permanently for an already installed system, edit the configuration file of the boot manager GRUB2, to be found under /etc/default/grub.

sudo nano /etc/default/grubThe following line is relevant:

GRUB_CMDLINE_LINUX=""You change these as follows:

GRUB_CMDLINE_LINUX="nomodeset"Press Ctrl+O to save and Ctrl+X to exit the editor.
Execute this to make sure that the changes in the /etc/default/grub file are also applied:

sudo update-grub
