Re: Computer doesn't turn off automatically when shutdown
Someone recently asked why their computer doesn't turn off automatically when they issue a shutdown command. In my case, it was because I installed SuSE with failsafe settings, and during installation when the SuSE installer created the /etc/lilo.conf file it added the failsafe settings to the default kernel, /boot/vmlinuz this is what that section of the /etc/lilo.conf file looked like: image = /boot/vmlinuz label = linux root = /dev/hda3 vga = 791 initrd = /boot/initrd append = " ide=nodma apm=off acpi=off hdd=ide-scsi" I believe that the automatic turning off of the computer is handled by APM (Advanced Power Management) or ACPI (Advanced Configuration and Power Interface). Although APM is enabled in my BIOS, it was turned off in the kernel by the "apm=off" kernel boot parameter, so when my computer reached runlevel 0 (halt) it did not turn off automatically. I edited my /etc/lilo.conf file and removed the parameters "ide=nodma apm=off acpi=off" from the append line of the default kernel, and my machine now automatically turns off when it reaches runlevel 0. I believe the "apm" parameter was responsible for this change, but it may have been the "acpi" parameter or both (I'm too new to Linux to know). Steve D
Thanks, these are good possibilities, but I'm using grub without the additional parameters. All I have is ide-scsi. Though I did notice that my vmlinuz is the same size as vmliniuz.suse. On Monday 27 May 2002 13:36, you wrote:

I wish it were that simple. Yes, I *had* to use failsafe to be able to install S-7.3, but I since long have discarded that " ide=nodma apm=off acpi=off " and my computer **still** doesn't shut off automatically. What bugs me even more is that S-7.2 (not to mention Win98) does it perfectly. If 7.2 can do it, why can't 7.3? P.S.: That failsafe setting (in my case) is needed *only* for the installation from the CD. Once the system is in the HD, it's not needed. Funny, isn't it? -- Regards, gr, in /usually/ sunny, balmy Florida's Suncoast. "I know all. My problem is that rarely can I recall any of it." /RHW/
