Do you run a nvidia linux driver? try nomodeset in kernel boot line.
To set kernel boot options, you must edit your grub configuration.
You can do this temporarily for a single boot by entering the grub menu.
If you do not get to see the grub boot menu after the bios automatically,
you may have to press SHIFT key after the bios logo to get in to grub:
Select the default ubuntu kernel (usually the top one), and rather than
pressing enter, press E to edit.
Press DOWN ARROW until you get to the line that starts with Code:linux /boot
and press END keys to position your cursor at the end of the that line
usually
ending with “quiet splash”.
Now you can type in additional kernel option: nomodeset
Press control+X to boot the modified grub entry
To permanently change the default kernel boot options, press ALT+F2 or open
a terminal from system > accessories > terminal.
Type in the following command:
Code:
gksudo gedit /etc/default/gruba text editor will open with the grub
configuration file. Near the top of that file you will see something very
similar to this:
Code:
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""add your custom boot options to the
GRUB_CMDLINE_LINUX_DEFAULT line, so for instance:
Code:
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
GRUB_CMDLINE_LINUX=""Save the file and exit gedit. If you have to add kernel
options that contain quotation marks, add them as such:
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_osi=\"Linux\""Now in
the terminal, run the following command to update your grub configuration
with the new default settings:
Code:
sudo update-grub
