New Lenovo Z585 A10 laptop.

I can boot the 64 bit Live CD fine - Try Ubuntu - dmesg contains lots of acpi stuff, Suspend is available etc.

When I do the install I am unable to boot without acpi=off in kernel line. Of course when booted I hav no suspend, no battery status etc...

Seems that casper is doing a bunch of things on the Live CD boot that I am not able to do with my install.

Help !!

open up terminal

sudo gedit /etc/default/grub In the grub file, change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off Save exit sudo update-grub reboot and viola !

  • Well, yes that is what I did... but don't want to. I want my on disk install to have the same capabilities as detected by the boot process off the livecd.

  • Oh okay have you tried booting with acpi=ht? Or nomodeset ?

  • Tried acpi=ht and nothing. Addedd nomodeset and at least saw text of the boot that stopped on an ACPI line. Thanks BTW.
