How do I set 'nomodeset' after I've already installed Ubuntu?


I know that editing the boot options line and adding 'nomodeset' solves my laptops problem during LiveCD mode, what I don't know is how to set it at boot up through Grub2 after I've installed Ubuntu.

So, my question is, how do I set nomodeset before I boot into Ubuntu?


To edit Grub2 during the boot process try the following:

Immediately after the BIOS splash screen during boot, press and hold the SHIFT button. This will display you grub containing a list of kernels and recovery options

Press e to edit the first kernel displayed

Find the line ending with quiet splash. Add your boot option before these key words - i.e. so the line looks like [...]nomodeset quiet splash Press CTRL + X to boot

Follow the steps in Coldfish's answer on how to fix the nomodeset boot option permanently so that you don't have to go through this manual procedure again.

You should add this option to /etc/default/grub, firstly:

When the boot menu comes up for the live CD I can use F6 to set "nomodeset" and that is the only way the live CD will run.

I've used this to install ubuntu 10.10 to the hard drive, there are no other operating systems or partitions (default swap/exf1). I've installed and reinstalled grub, and grub-install -v gives:
grub-install (GRUB) 1.98*20100004-5ubuntu3

So when I boot from harddisk I need to use nomodeset, and I can't figure out how to do this. /boot/grub has no menu.lst file and I don't get a GRUB menu, which isn't important except that any instructions I've found are from the GRUB menu.

I can run the live CD, or boot to microubuntu prompt, but from either I don't know how to set my boot or cause a boot with nomodeset. Command line is fine, but I'd also like to know how to permanently make the HD boot with nomodeset as well in case I can't get a proper driver or whatever once I boot into...

I am trying to use a RX560 with Ubuntu 16.04.3 64bit. First off, I could not get the default Ubuntu installer to work, I had to edit a init kernel options to add nomodeset and then it started up so I could install Ubuntu. Even after installing and updating my Ubuntu, I still have to set nomodeset in my /etc/default/grub file as part of the kernel options for boot.

If I dont set nomodeset, shortly after GRUB menu selection is made/done it goes to blank screen and freezes.

I came across a post on these forums suggesting to use Linux kernel : 4.8.0-58-generic

I have tried the following kernels all of which experience the same problem:

4.13.0-32-generic (lastest kernel introduced through updates)

4.10.0-28-generic (kernel installed by installer)

4.8.0-58-generic (recommened kernel that user said worked for him)

So with the < 4.10 versions, I could not run the AMGGPU-Pro 17.40 installation successfully (by executing...

This is what’s gonna give you headaches. Leap 42.3 ships with kernel 4.9. I don’t own any nvidia hardware and try to get it working in linux but I found documentation that might give you good starting point.

Read up on it here, linked for convenience.

1.4 Update of Kernel Graphics Stack

On openSUSE Leap 42.3, the upgrade of the graphics stack up to 4.9.x kernel code is provided via the package drm-kmp-default instead of backporting many patches into the kernel itself. Usually, this package is installed automatically during the OS installation when a corresponding graphics device is found on your machine.

The KMP gives users also another benefit: You can roll back to the 4.4.x kernel code by uninstalling this package. If you face critical issues, like a hung GPU, try to uninstall the package as shown below, then reboot and retest:

NVIDIA Linux driver 375.39 and 378.13, the latest long-lived and short-lived branch versions, were both released yesterday.

Both drivers add support Quadro GP100, P4000, P2000, P1000, P600. P400, M1200, M2200 GPUs support. NVIDIA 378.13 also supports Quadro P3000.

Besides adding new GPUs support, Nvidia 375.39 only brings fixes to hot-plugging displays and resuming from suspend issues.

Nvidia 378.13 adds support for viewing configured PRIME displays in nvidia-settings, support for X.Org xserver ABI 23, and various other changes and fixes. See HERE for details.

Download & Install Nvidia 375.39 / 378.13:

NOTE that following steps is not recommended for beginners! Installing the proprietary drivers may cause blank screen and you have to know how to troubleshoot, such as

setting NOMODESET in grub

, or remove the driver from command console.

Besides using the official installers from the NVIDIA website, the “Graphics Driver” team...

This is a how to guide on fixing the booting error of the fresh Ubuntu 14.04 LTS installation (or upgrade) please follow the video and you will understand it.

Hello guys,

I am gonna show you how you can fix the bug when you've
already installed Ubuntu 14.04 LTS, and you want to load
it up for the first time, but then an error pops out.

Well here it is....

First what you want to do is turn off your PC and reboot it

Then (if dual booting) select Ubuntu. After you done that,
the Ubuntu GRUB will come up (the purple screen with 2
options "Ubuntu" and "Advanced booting options") you will
touch nothing. Just press the key "e" on your keyboard as
it stands for "edit". Move with your arrows and navigate
to the line
linux /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321
loop=/ubuntu/disks/root.disk rw quiet splash $vt_handoff

in this line you will find the RO part....change that...

After Installing Ubuntu 14.04 Trusty Tahr, there are a wealth of things that need to be dealt with, including Hardware Drivers, DVD, Audio and Video Codecs, Archiving formats, generally useful stuff.

These instructions presume you are proficient with PPAs, .Debs, and other terminal commands, Ubuntu Tweak, and require a full set of video, audio, and archive codecs, as well as Skype, Flash, and a truck-load of wallpapers.


Using the sudo command can result in severe system damage. Read all instructions and confirm you understand before executing any commands.

Make sure you type commands correctly, or copy and paste the entire code. Your first click will highlight all the code, or you can double click in the code area to do it again.

This guide is to set nomodeset parameter into the boot process which is very useful for the AMT

dedicated servers

and will allow the server to display the screen onto the VNC viewer plus correctly.

1. Install the O/S. In Debian choose the normal installer with out graphics. In Ubuntu just run through the installer like normal.

2. After completion reboot the server as normal but interrupt the default boot in GRUB by hitting the arrow keys.

3. Highlight the very first, top option and hit 'e'

4. Scroll down on the editor and look for the line that starts with 'linux'. Once found append to the end of the line with 'nomodeset'

5. Press 'F10' to boot. The server should boot and not disconnect if done correctly.

6. Login as 'customer' and switch to 'root' either by executing 'su' or 'sudo su' in Ubuntu

7. Execute 'nano /etc/default/grub'

8. Look for the line 'GRUB_CMDLINE_LINUX_DEFAULT=""' and change it to...

I'm new to Ubuntu but wanted to try it on my Intel NUC NUC5i5RYH. I've tried to install 14.04 LTS and 14.10 from a USB stick I made, but with both of these during the installation process all the onscreen UI (like the 'next', 'continue', 'ok' buttons) are blacked out and the window where the installation dialogue should be is just a black empty window. This meant I wasn't able to complete the install as I didn't know where to click to proceed. I tried instead running Ubuntu from a live CD and on the desktop the onscreen UI (like the maximise and close buttons) are all similarly messed up/glitchy.

I have managed to get the Ubuntu 15.04 beta to install from a USB stick and this seems to fix whatever problem is occurring but I'd prefer to be running 14.04/14.10.

Ubuntu 17.04 is finally here with a number of major changes like app installation via snaps, the use of swap files, and an updated Linux kernel 14.0.

Apart from major bug fixes, performance improvements, and UI tweaks here and there, Ubuntu looks pretty much the same. Nevertheless, this article aims to provide new Ubuntu users with a sense of direction while providing an avenue for long-term users to share their set-up preferences.

So, without further ado, let’s get to the First 10 Things you should do after installing Ubuntu 17.04 (Zesty Zepus).

1. Check for Updates and Install Graphic Drivers

This is to make sure you have the latest security patches, bug fixes and support for software integration features. It is also important for you to make sure that you have the latest graphic drivers installed as they will allow you make the best use of your computer’s performance whether you’re using its processor features, GPU, or WiFi.

I installed Ubuntu 11.10 as a partition on the same HD as my Windows 7; after rebooting the HD would not boot into either OS. I've tried to set partition flags to 'boot' but it does nothing. Should there be some files I need in /boot ?

I'm able to mount and access the files on either partition but I can't boot into them. (Only able to boot from USB).

Please help.


edit: I've added boot info script and here's the result:
