If you're facing graphical issues when booting your flavour of linux, you may need to enable nomodeset. This disables the graphics driver just for the boot, and then starts it once the OS is loaded. This prevents kernel incompatibilities with some drivers especially with newer GPUs.

What is Nomodeset in Linux?

Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded. This has no negative side effects: only your boot process will be a bit less beautiful.


How do you use Nomodeset?
Nomodeset boot option

In BIOS mode, highlight Start Linux Mint and press Tab to modify the boot options. Replace quiet splash with nomodeset and press Enter to boot. Repeat this operation post-install in your grub boot menu and read Hardware drivers to install additional drivers.


How do I remove Nomodeset from grub?
You need to change and update default configuration file. Save file then exit editor. On next boot nomodeset is active by default. When the driver issue will be fixed, you will have to edit file /etc/default/grub to remove nomodeset boot parameter option, and update grub using “sudo update-grub” in a terminal.


What is Nomodeset Xforcevesa?
The parameter “nomodeset” disables “the kernel mode setting” (tells the kernel to not set the graphic resolution, let X do that instead). The parameter “xforcevesa” enforces to use the VESA driver for X.


How do I permanently install Nomodeset?
Procedure to add nomodeset to grub:

Stop the installation to the grub menu.
Press e to edit the menu entry you choose (e.g Install Ubuntu) and it will lead to edit the boot parameters.
Find the line which ends with quiet splash and add nomodeset in front of it. …
Press Ctrl+X or F10 to boot with this new parameter.


What does Nomodeset mean?
nomodeset – tells the kernel to not start video drivers until the system is up and running.


What is Grub_cmdline_linux_default?
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” This line imports any entries to the end of the ‘linux’ line (GRUB legacy’s “kernel” line). The entries are appended to the end of the normal mode only. To view a black screen with boot processes displayed in text, remove “quiet splash”.


What is nouveau Modeset?
nomodeset disables more features than the nouveau drivers for the NVIDIA GPU and nouveau.modeset=0 disables only the nouveau drivers for making use of the NVIDIA GPU.
