hello,

i am using windows xp and suse 10.2 with dual boot via grub loader on my computer.

under linux there is a option "suspend to disc", so that i can switch off the computer and start working at the same position after a restart.
my problem is, i want to use this option for conveniency to switch to windows system.

this is so far not possible, since after "suspend to disc", the computer automatically boot into linux partition, without ask me for the selection of the OS.
i can see the first two lines of grub loader, but then the computer directly starts linux.

how can i solve this problem?

thanks for answers.

I don't think you can. My Fedora 7 box does this too. I think the only thing you can do, if you want to be able to start Windows the next time you boot your computer is to shut it down completely. I am not sure about this, though, someone might have a solution for you, that actually allows you to use both suspend to disk and allows you to choose OS at boot time.

In the mean time you could set KDE to restore previous session under Control panel --> KDE components --> session manager. If suse has some kind of special control panel, either find your way around that by your self, or start the KDEs standard one with alt+f2 and the command
$ kcontrol

It seems to me that "suspend to disc" is intended to save your environment so that you can go back to it later. This has no value or meaning if you are going to go back to Windows--or even to another Linux distro.

If you tell us what you are trying to do, then there might be another solution.

Note that SUSE has an option in the shutdown menu to automatically restart in other OSes.

I think the reason for this behavior (you should Google) is that the "state" of your system is saved to your /swap partition (by default) and since other distros might be installed and they would use the same swap partition this behavior keeps the "saved to disc" image from being over-written if one of the other distros were loaded. That you want to load Windows which is not using /swap is not handled by grub.

Hi bussard vago,

I concur with you that being able to suspend to disk in Linux and reboot in another operating system is important!

And I claim it is easily possible and safe.

The reason why by default it does not work is that the pm-utils utilities modify the GRUB loader upon suspension, in order to have the suspended system rebooted automatically the next time.

This is done by a script that can be modified.

Here is the procedure

• Become super-user.
• Go to the directory /usr/lib/pm-utils/sleep.d
• Locate a file called something like 99Zgrub
• Make a copy of this file for security, NOT in the same directory.
• Edit the file and locate in it the function
  grub-once()
  {
  ....
  }
• Comment all the code of the function using # characters
• Write below another grub-once() function as follows:
  grub-once()
  {
  echo -e "savedefault --stage2=/boot/grub/stage2 --default=$1 --once\nquit" | grub --batch
  }
• Save the file.

You can now suspend to disk. Upon reboot, you will be offered the GRUB menu and be able to choose Linux again (and the system will resume from disk) or to choose another operating system.

Disclaimer: I tested this solution under OpenSuse 10.3; I am not sure it works also under version 10.2; but it should.

Cheers
