[SOLVED] cancel resume from suspend

Hi,
I have suspended my machine instead of turning it off to boot temporarily into Windows. Now I want to go back to archlinux, but I don't want to resume the session, but restart normally. How can I cancel the resume process in arch? Everytime I reboot, it keeps dropping back into the password prompt to give the password to decrypt the swap file and resume, but I don't want to resume!

Removing resume=/dev/swap from grub does not solve my problem.

Any advice appreciated!

PS: What happens if I forget the password for resume? How would I be able to boot then?

I think what you wanna do is hibernate instead of suspend

Re: [SOLVED] cancel resume from suspend

I think that is what I am doing I thought suspend was the same as hibernate. I am using s2disk and then when I want to wake up, I just don't want resume, but reboot and abandon the RAM image...

No, suspend is s2ram and hibernate s2disk. So when you turn your computer back on after hibernating, does it start up as normal. What I mean is: does grub come up after turning on your computer after hibernating?

Re: [SOLVED] cancel resume from suspend

Try "noresume" in the kernel line in GRUB.

Re: [SOLVED] cancel resume from suspend

that didn't work, unfortunately:
First, I hibernated. Then, I turned the computer back on, and edited the kernel line in grub:

But I still get a password prompt:

Re: [SOLVED] cancel resume from suspend

Try "disablehooks=uresume" then.

Note that skipping resuming means no proper unmounting of filesystems, hence a risk of filesystem corruption and data loss.

Re: [SOLVED] cancel resume from suspend

yes, I realize that, thanks, lucke, since you mention it, here's why I need it:

I auto-mount my windows partition on my dual-boot machine when running in archlinux, and most of the time, I just hibernate linux by closing the lid of my laptop. Very rarely I boot into windows when turning the laptop back on. However, I am using qbittorrent to download to my windows partition, since it has a lot more space and I don't want to repartition, but I am downloading through archlinux. So when I hibernate, the files on the windows partition are still "open", and the filesystem is still mounted. Now if I boot into windows when I turn the computer back on, I will run into trouble if after that, I resume back into archlinux, because the files on windows will have changed and arch will be confused. In that case, I have to just throw away the resume-image in arch to start from scratch. Hope that made sense.

Re: [SOLVED] cancel resume from suspend

Yeah, I know the problem. I lost some files because of dual-booting that way myself. Alternatively, you could use pm-utils hooks to kill qbittorrent and unmount Windows' partition before hibernating, but it comes with its own problems and if you do it rarely enough, I suppose skipping resuming is better indeed.
