This work for me. I updated the boot parameters by following the guide on https://wiki.ubuntu.com/Kernel/KernelBootParameters
Permanently Add a Kernel Boot Parameter
- Log in to the system and start a terminal window.
- Edit the /etc/default/grub file >>sudo nano /etc/default/grub
'## If the file /etc/default/grub appears to be empty or does not exist, see the instructions for earlier releases above in https://wiki.ubuntu.com/Kernel/KernelBootParameters.
- In the editor window, use the arrow keys to move the cursor to the
line beginning with "GRUB_CMDLINE_LINUX_DEFAULT" then edit that line,
adding your parameter(s) to the text inside the double-quotes after the
existing text (to disable Power Saving Mode add consoleblank=0 inside
the quotes)
GRUB_CMDLINE_LINUX_DEFAULT="nomdmonddf nomdmonisw consoleblank=0"
its a good practice to add a comment line to explain what you did. Use
the '#' character at the start of the line to indicate it is a comment.
'# added consoleblank=0 20180224 to stop power saving mode'
- overwrite the nano file ctrl+o and exit nano ctrl+x
- update grup >>sudo update-grub
- Restart the system.
Note: The parameter(s) you've added to the GRUB_CMDLINE_LINUX_DEFAULT
line are persistent, and will be in effect for every subsequent boot
session (unless you remove them by repeating the procedure above).
