Why do I always need to go to grub and enter in Ubuntu?

  • 772

I am using Ubuntu 18.04 LTS on Dell Vostro 15 - 3546.

uname -a :

Linux <laptop-name> 4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

When I open my laptop from shutdown the boot screen gets stuck. Hence I followed this and added nomodeset after quiet splash in /etc/default/grub . Then I further added acpi_backlight=vendor after that, due to brightness problems. Now, the line looks like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor"

After this, I need to manually hold Shift during the boot and need to Enter into Ubuntu. However, It still gets stuck on the boot screen, so I need to again hold the Power button and force shutdown. Then, when I again Enter into Ubuntu, I am finally able to open the device.

This procedure is too long and please help me solve this issue.

Thanks in advance.

  1. Try adding/substituting these lines to your /etc/default/grub
    GRUB_DEFAULT=0
    #GRUB_DEFAULT=saved
    #GRUB_SAVEDEFAULT=true
    #GRUB_TIMEOUT_STYLE=hidden
    GRUB_TIMEOUT_STYLE=menu
    GRUB_TIMEOUT=10

    Don't forget to run sudo update-grub before you reboot.
