Speaking of swap... is there a way to get rid of it altogether?
I know you can set the ”swappiness” but I would rather have all space on SSD available.
I have a laptop with 16 GB ram and there is no need for any sort of swap.

This post was moved here from another thread on the forums. To remove swap completely: sudo swapoff -a -v
sudo rm /swapfile
# back up /etc/fstab:
sudo cp /etc/fstab /etc/fstab.bak
sudo sed -i '/\/swapfile/d' /etc/fstabI am assuming in fstab the swap file is called swapfile. You may want to open the file in a text editor and verify that, if it is called something else use that name in the above set of commands. If you can reboot and all works ok you are good to go. You can safely remove the fstab.bak if you wish. |

I dunno if it matters, but I think (I defininteily could be wrong) you need a swap partition in order to be able to hibernate? But I dunno how that relates to a swap file.

Thank you. It worked.. I'm a bit tired to study the purpose of sed so that would be for another day.

But anyway he asked the question, I answered and it is useful information. After all I don't even use hibernate, but i do keep a swap file around. I haven't looked but hopefully if ya can't hibernate that option in the menu is greyed out and inactive. I think you can get better performance if you move the swap file to a Ram disk or something, if you have the mem to spare. I will leave that topic and tweaking swap in general to others if they wish to elaborate. |

Hibernation is disabled by default in Ubuntu. Clicking the hibernate button does not work in Moksha, but it's not greyed out.

We need to fix that, perhaps not even display that on Bodhi. I will have to look into it. Thanks For now all you need to do is open the file /etc/enlightenment/sysactions.conf as root and comment out the line: action: hibernate sudo pm-hibernateBodhi by default is using pm-utils to do this kind of stuff. But you can change this file to use systemctl if you wish. For an experiment I created an enlightenment deb file that could coexist with moksha. Enlightenment installed to /usr/local. I placed this in BL5.0 testing repo and in doing so I had to change the /etc/enlightenment/sysactions.conf to use systemctl as that is what enlightenment wants to use. Whatever the case the action: hibernate line needs commented out and then the menu item for Hibernate will be inactive and grayed out. However it doesn't hurt to leave it as it is as you note it does nothing. If you are brave and your system can actually safely hibernate you are free to enable Hibernation in Bodhi. Easy enough to find out how to do so on Ubuntu online. |
