I have recently installed Ubuntu 12.04LTS on an old Toshiba laptop. In order to do this, through trial and error I have found I must set acpi to off. Now, whenever I try to boot, I must also set acpi=off in the GRUB boot options.
Is there a configuration file that I can modify with acpi set to off, so that I don't have to do it each time I boot?
Thanking you in advance,
