Adding boot parameters to grub

To add a boot time parameter to grub you can select the Q4OS boot entry (usually already selected) and then press e which will put you in edit mode, you will then be presented with a screen like the one below

To add a boot parameter simply locate the line that begins linux    /boot/vmlinuz... and add at the end of that line the parameter ie "acpi=off" like in the screenshot below.

and then press Ctrl-x or F10 to boot the system.
This will add the boot parameter for this session only.

To make this change permanent:

From a terminal (konsole) run:

sudo nano /etc/default/grub

and enter your password.
Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and append acpi=off (for this example) to its end. For example:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

Save the file and close the editor (press Ctrl-x then type y followed by pressing enter).

Finally, start a terminal and run:

sudo update-grub

to update GRUB's configuration file.

Re: Adding boot parameters to grub

Someone from North America!

Glad that worked as its a common problem with older laptops and bios.

RJ45 doesnt work, thats curious as Ive never had that issue with that system.

Trying to remember but I think it uses a Brioadcom Lan driver so we may need to install a Broadcom driver but typically Ive only seen them for wireless chipsets.

Glad youve got WIFI.

Re: Adding boot parameters to grub

I believe youre using the Broadcom BCM4401 ethernet controller so might find this article from 2010 interesting,

http://askubuntu.com/questions/14970/br … -tx-issues

It could also be that there isnt a driver available as I dont see the b44 driver listed in Synaptic.

So far Q4OS has been fine with all my Dell laptops that use Broadcom chipsets but many use Intel chipsets for ethernet.

Heres the tech manual for your laptop,  http://tim.id.au  click on laptops, then in the right column click on Acer, slide down the page and under Travelmate click on the 4500 pdf.
