Re: [CentOS] Getting hibernate to work on a new CentOS 7.2.1115 install
Hi, I wanted to see if anyone had any suggestions on what I could do to get hibernate working. Just as a reminder, I get: > cat /sys/power/state: freeze mem > cat /sys/power/disk [disabled] > The first should include 'disk' and the second should say enabled or some such. So, clearly this is not set correctly. How do I make these changes, if I am allowed to? > Note that hibernation is probably not supported by theCentOS kernel if this > is on a UEFI computer with Secure Boot enabled (it's not supported by Fedora kernels) as it's a possible vector to defeat the point of Secure Boot. I do have SecureBoot disabled (the computer would not boot after installation otherwise) and that is when I found the hidden "flag" to disable SecureBoot. > And yet another thing is that it's possible the initramfs isn't using resume= which is currently a problem on Fedora. So you might need to add this to the grub.cfg on the kernel command line, something like resume=/dev/VG/swap or wherever it is. If it's a /dev/sdXY, i.e. on a regular partition, then use UUID. I know how to get it working on Fedora (modify /etc/default/grub and grub-instlall) or so I believe. Should I have to do the same thing on CentOS? Thanks again! - ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Do you have sufficient SWAP configured on your system? ___ Thanks! The machine in question has 2 GiB of memory. I asked for an automatic partitioning of the disk during installation and the installer chose 3.some GiB. I usually use twice the RAM but I let it go this time since it was what was recommended by the automatic anaconda. What swap should I go for there?

[CentOS] Getting hibernate to work on a new CentOS 7.2.1115 install
Hi, I am a new CentOS user (quite familiar with Fedora 1-23+) and I decided to try a new install of CentOS on a ASUS R503U. However, I can not get hibernate to work. I try: systemctl hibenaate and I get: Failed to execute operation: sleep verb not supported Btw, the problem does not go away with super-user. I was wondering how to get around this issue. I would like the abililty to hibernate and come back in the last state. Thanks! ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] CentOS 7.1 How to change panel background
Hi, I just installed CentOS and have been trying to change the desktop panel background (in gnome classic) to black. How do I do this? Holding the alt button while right-clicking on the mouse does not seem to do anything. I do not have anything installed (other than what came with the LiveCD). Many thanks! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
