Ubuntu – Stop Ubuntu from loading GUI

14.04bootgui

I have read all the other info about this subject but can't get this to work.

I have a Tegra Jetson TK1 board with Ubuntu 14.04 on it, I tried to update and upgrade Ubuntu, but now I can no longer see anything on my screen after the initial start (the list of tasks in text mode and NVidia logo shows up and then the screen goes black).

I tried to hold the shift key while booting, push Ctrl-Alt-F1 among other things, but I can not stop the GUI to load.

Anyone knows hoe I can get a terminal so I can recover the OS?

Really appreciate you help.

I've worked with the Jetson TK1 and upgrading/updating Ubuntu is a known issue. The libglx.so file gets overwritten. You need to run: "sudo apt-mark hold xserver-xorg-core" before updating. See wiki page here for more info: http://elinux.org/Jetson_TK1#An_important_step_before_connecting_the_Jetson_to_Internet

Apparently this has been solved with the latest TK1 image provided by Nvidia.

I've had the best luck flashing the device using the JetPack. (https://developer.nvidia.com/jetson-tk1-development-pack). It requires Ubuntu 12/14 64-bit. And for some reason it takes up a many gigs of disk space and I can't seem to get rid of it even after uninstalling. You might want to take a snapshot before installing if you're using a VM.

Hope that helps.

Ubuntu – Ubuntu stops loading

Setting nomodeset in the F6 menu on booting solved the problem.

Safe Graphics Mode. A new option is added to the GRUB menu in 19.04 and later which will boot with nomodeset on. This may help you resolve issues on certain graphics cards and allow you to boot and install any proprietary drivers needed by your system.

From the purple ubuntu screen press the F6 key. If you don't see this screen, shutdown, boot from the Ubuntu live USB again, and immediately after the BIOS/UEFI splash screen during boot, with BIOS, quickly press and hold the Shift key, which will bring up a GNU GRUB menu screen. With UEFI press (perhaps several times) the Esc key to get to the GNU GRUB menu screen. Sometimes the manufacturer's splash screen is a part of the Windows bootloader, so when you power up the machine it goes straight to the GNU GRUB menu screen, and then pressing Shift is unnecessary.

If the Ubuntu installer either does not start or starts and then freezes, press the F6 key and enable the nomodeset kernel boot option by following the instructions in the nomodeset tag wiki.

Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. Rufus can be especially useful in cases where bootable media created in Windows by other GUI Linux live USB creators such as Universal USB Installer and UNetbootin gets stuck and won't boot. Rufus is the recommended application at the official Ubuntu website for making a bootable live Ubuntu USB on Windows. Rufus can also make a bootable Windows 10 USB.

System requirements

Windows XP or later, 32-bit or 64-bit

Usage

You will need a 2GB or larger USB flash drive and an Ubuntu iso file. For Ubuntu 18.04 and later the USB flash drive should be 4GB or larger. Download the Rufus executable file for Windows from here and run it. No installation is necessary.
Select your device volume label.
Click the drive image to select the Ubuntu .iso file.
If it's an Ubuntu .iso, Rufus will automatically select the FAT32 file system.
Click Start, and a message will appear saying that all of your USB data will be deleted and the USB drive will be formatted.
Click OK.
Click Close.

Rufus is not the strongest of all programs for creating an Ubuntu live USB that will boot without fail. The strongest method is to use a terminal program called dd to write the Ubuntu Minimal CD to a USB flash drive. Unfortunately dd is not a Windows program unless you have Windows Subsystem for Linux (version 2 or later recommended) or Cygwin installed in Windows.

Ubuntu – Broken 14.04 LTS while upgrading to 16.04

You could try booting into an older kernel from the grub menu. Holding the shift key while booting should give you the grub boot menu.

Hopefully you will see a newer kernel that was installed as part of the upgrade and also an older kernel version to boot into.

If the older kernel is an option then boot into it. Then you can try to fix any broken packages with

sudo apt-get -f install

From previous experience I normally give up and do a clean install if things don't go smoothly when upgrading. In fact when I went from 14.04 to 16.04 I just choose the clean install option. You may be able to perceive and fix the boot problem only to find other issues exist and you may spend more time than its worth fixing them.

Worst case (and probably easiest option) I would suggest using a live cd to boot and get all your files off onto a USB drive then clean install.
