I can't remember exactly, but in this case you must enable acpi management in grub editing the corresponding line of your os in /boot/grub/menu.lst do a google search about activating acpi in the selected OS in GRUB... Gock ;) <div>2007/11/5, Alex Janssen <<a href="mailto:alex@ourwoods.org">alex@ourwoods.org</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Since installing Gutsy 2 weeks ago, I cannot hibernate or reboot the computer. Both functions lock up after starting into the sequence. They get as far as returning to the text screen. I used to be able to do these things with Feisty. The only thing I can do now is just shutdown. What log files should I look in and what am I looking for? I'm hoping I can simply reinstall something to fix this. :-) Thanks, Alex -- <a href="http://Ourwoods.org">Ourwoods.org</a> Why should I waste my time reliving the past when I can spend it worrying about the future? - Jasper Dangle (328) -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com </a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> -- Andrés "Majes" Mochi Mella Administrador de <a href="http://www.MeHaDejado.com">http://www.MeHaDejado.com</a>
