Keep running programs but suspend while not consuming almost at all battery

[Benjamin-Loison]

At least twice I suspended my Linux Mint 22 Cinnamon Framework 13 with 5% of battery and try resuming it afterwards but it shutted down.

According to Benjamin_Loison/Debian/issues/105, I am looking for S4 state.

Related to #115 and Benjamin_Loison/linux/issues/29.

systemctl hibernate

Call to Hibernate failed: Not enough suitable swap space for hibernation available on compatible block devices and file systems

htop shows 33 G of swap and 4.17 GB of RAM used over 31.3. So as the mentioned person uses a swap partition, it may require a swap partition and not a swap file.

ls -lh /file.swap

-rw------- 1 root root 32G Mar 10  2024 /file.swap

[Benjamin-Loison]

[Benjamin-Loison]

According to the person on another OS booted from the same disk when hibernate the home folder is shown as encrypted by ecryptfs (after ecryptfs-migrate-home).

Unclear if have to decrypt swap then home folder or the other way around, as possibly decrypting swap requires decrypting the home folder first or the other way around according to the person.

So according to the person have to specify 2 passwords. Maybe 2 passwords as the purpose of swap is to be common to all users but not the home folder.

As the swap is encrypted in theory, we reach strong encryption while keeping running state it seems.

[Benjamin-Loison]

The person achieved with 40 GB of swap for the 32 GB RAM work laptop.

Description: ext2/ext3/ext4 file system utilities
 The ext2, ext3 and ext4 file systems are successors of the original ext
 ("extended") file system. They are the main file system types used for
 hard disks on Debian and other Linux systems.
 .
 This package contains programs for creating, checking, and maintaining
 ext2/3/4-based file systems.  It also includes the "badblocks" program,
 which can be used to scan for bad blocks on a disk or other storage device.

So the version is fine.

Shrinking the next big encrypted Debian partition does not look like a good idea but the previous partition with Windows using BitLocker may be better.
It does not propose shrinking Windows. Let us try temporarily disable BitLocker.

The person let about 90 GB for Windows.

Is this screenshot from another OS instance? If not, should try another OS instance.

I would say that it is the same OS as trying to reproduce the screenshot leads to a very similar result:

So let us try on currently installed Ubuntu.

Maybe opening the encryption helps.

NAME
       lvreduce — Reduce the size of a logical volume

SYNOPSIS
       lvreduce option_args position_args
           [ option_args ]

DESCRIPTION
       lvreduce  reduces  the  size  of  an LV. The freed logical extents are returned to the VG to be used by other LVs. A copy-on-write snapshot LV can also be reduced if less space is needed to hold COW
       blocks. Use lvconvert(8) to change the number of data images in a RAID or mirrored LV.

       Be careful when reducing an LV's size, because data in the reduced area is lost. Ensure that any file system on the LV is resized before running lvreduce so that the removed extents are not  in  use
       by the file system.

       Sizes will be rounded if necessary. For example, the LV size must be an exact number of extents, and the size of a striped segment must be a multiple of the number of stripes.

       In the usage section below, --size Size can be replaced with --extents Number.  See both descriptions the options section.

           [    --version ]

OPTIONS
       -A|--autobackup y|n
              Specifies if metadata should be backed up automatically after a change.  Enabling this is strongly advised! See vgcfgbackup(8) for more information.

       --commandprofile String
              The command profile to use for command configuration.  See lvm.conf(5) for more information about profiles.

       --config String
              Config  settings for the command. These override lvm.conf(5) settings.  The String arg uses the same format as lvm.conf(5), or may use section/field syntax.  See lvm.conf(5) for more informa‐
              tion about config.

       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file and/or syslog (if configured).

       --devices PV
              Restricts the devices that are visible and accessible to the command.  Devices not listed will appear to be missing. This option can be repeated, or accepts a comma separated list of devices.
              This overrides the devices file.

       --devicesfile String
              A  file  listing  devices that LVM should use.  The file must exist in /etc/lvm/devices/ and is managed with the lvmdevices(8) command.  This overrides the lvm.conf(5) devices/devicesfile and
              devices/use_devicesfile settings.

       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.  For testing and debugging.

       -l|--extents [-]Number[PERCENT]
              Specifies the new size of the LV in logical extents.  The --size and --extents options are alternate methods of specifying size.  The total number of physical extents  used  will  be  greater
              when  redundant data is needed for RAID levels.  An alternate syntax allows the size to be determined indirectly as a percentage of the size of a related VG, LV, or set of PVs. The suffix %VG
              denotes the total size of the VG, the suffix %FREE the remaining free space in the VG, and the suffix %PVS the free space in the specified PVs.  For a snapshot, the size can be expressed as a
              percentage  of  the  total size of the origin LV with the suffix %ORIGIN (100%ORIGIN provides space for the whole origin).  When expressed as a percentage, the size defines an upper limit for
              the number of logical extents in the new LV. The precise number of logical extents in the new LV is not determined until the command has completed.  When the plus + or minus - prefix is used,
              the value is not an absolute size, but is relative and added or subtracted from the current size.

       -f|--force ...
              Override various checks, confirmations and protections.  Use with extreme caution.

       -h|--help
              Display help text.

       --journal String
              Record  information  in the systemd journal.  This information is in addition to information enabled by the lvm.conf log/journal setting.  command: record information about the command.  out‐
              put: record the default command output.  debug: record full command debugging.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       -n|--nofsck
              Do not perform fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with this option.

       --nohints
              Do not use the hints file to locate devices for PVs. A command may read more devices to find PVs when hints are not used. The command will still perform standard hint file invalidation  where
              appropriate.

       --nolocking
              Disable locking. Use with caution, concurrent commands may produce incorrect results.

       --noudevsync
              Disables  udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible udev processing in the background. Only use this if udev is
              not running or has rules that ignore the devices LVM creates.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --verbose.  Repeat once to also suppress any prompts with answer 'no'.

       --reportformat basic|json
              Overrides current output format for reports which is defined globally by the report/output_format setting in lvm.conf(5).  basic is the original format with columns and  rows.   If  there  is
              more than one report per command, each report is prefixed with the report name for identification. json produces report output in JSON format. See lvmreport(7) for more information.

       -r|--resizefs
              Resize underlying filesystem together with the LV using fsadm(8).

       -L|--size [-]Size[m|UNIT]
              Specifies the new size of the LV.  The --size and --extents options are alternate methods of specifying size.  The total number of physical extents used will be greater when redundant data is
              needed for RAID levels.  When the plus + or minus - prefix is used, the value is not an absolute size, but is relative and added or subtracted from the current size.

       -t|--test
              Run in test mode. Commands will not update metadata.  This is implemented by disabling all metadata writing but nevertheless returning success to the calling function. This may  lead  to  un‐
              usual error messages in multi-stage operations if a tool relies on reading back metadata it believes has changed but hasn't.

       -v|--verbose ...
              Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr.

       --version
              Display version information.

       -y|--yes
              Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution.  (For automatic no, see -qq.)

VARIABLES
       LV     Logical Volume name.  See lvm(8) for valid names.  An LV positional arg generally includes the VG name and LV name, e.g. VG/LV.

       String See the option description for information about the string content.

       Size[UNIT]
              Size  is an input number that accepts an optional unit.  Input units are always treated as base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.  The default in‐
              put unit is specified by letter, followed by |UNIT.  UNIT represents other possible input units: b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P
              is PiB, e|E is EiB.  (This should not be confused with the output control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES
       See lvm(8) for information about environment variables used by lvm.  For example, LVM_VG_NAME can generally be substituted for a required VG parameter.

EXAMPLES
       Reduce the size of an LV by 3 logical extents:
       lvreduce -l -3 vg00/lvol1

DuckDuckGo and Google search Linux reduce physical volume.

[Benjamin-Loison]

As I don't know how to reduce LVM size to the logical volume of it, let us try with default ext4, as on the laptop owned by the person:

Face:

systemctl hibernate

Call to Hibernate failed: Not running on EFI and resume= is not set. No available method to resume from hibernation

without having specified Firmware UEFI in Virtual Machine Manager, so as htop shows correctly the request password at boot encrypted swap, it should work on an actual computer.

I accordingly proposed to the mentioned person to encrypt his laptop, see Signal of 19/06/25 at 12:00.

The person orally told me that not much interested finally.

[Benjamin-Loison]

Maybe searching Linux Mint hibernation with full disk encryption would help.

[Benjamin-Loison]

on my Debian 12 GNOME work laptop.

Can't have 2 partitions under the same LUKS encrypted container?

So contrarily to Linux Mint 22.1 Cinnamon, see #issuecomment-2600090787, Debian 12 GNOME does not use LVM intermediary container, so it is not a must.

[Benjamin-Loison]

It is what Linux Mint 22.1 Cinnamon does on disk encryption install with LVM but as shown above does not work. So the question is more precisely can we put 2 partitions like ext4 and swap without LVM in a singled dncrypted LUKS container?

The aim being to request a single password assuming a single user usage, especially the case on work laptop.

[Benjamin-Loison]

If I remember correctly since I established this setup on my Debian 12 GNOME work laptop, I sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y and installed a new kernel and before and after this new kernel install systemctl hibernate and resuming from hibernation works fine.

[Benjamin-Loison]

Related to Benjamin_Loison/openssh/issues/40.

[Benjamin-Loison]

nvidia-smi

works fine with secure boot disabled even after reboot.

[Benjamin-Loison]

Maybe related to Benjamin_Loison/Debian/issues/129.

Let us try to add graphical button to hibernate as in work tutorial at:

/etc/polkit-1/rules.d/ was already existing but adding to /etc/polkit-1/rules.d/10-enable-hibernate.rules:

polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.login1.hibernate" ||
        action.id == "org.freedesktop.login1.hibernate-multiple-sessions")
    {
        return polkit.Result.YES;
    }
});

have not graphically added an option even after a reboot on Debian 12 GNOME.

does not know how to shrink LUKS (he only knows how to do for LVM with documentation) but he is fine taking 30 minutes to do so it seems.

[Benjamin-Loison]

According to the person:

an alternative concerning LUKS would be to delete and recreate shorter but then have to copy the data elsewhere.

According to this person the hibernate button should work fine on GNOME even if I told him that no. As far as I remember he uses XFCE on Ubuntu 24.
