Thread: start up SLED

  1. #1

    start up SLED

    This is an issue I have seen in SLED 15.0 only.

    I can hybernate the PC, no problem. But when I start up fresh, from time to time, randomly, the boot goes fine to login, but thereafter stops before activating the desktop. A hard reset usually helps.
    Any idea how I can solve that?

    Hi
    Maybe a UUID issue with swap (assuming it's 1.5 times installed RAM), if you check the output from;

    Code:
    cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
    Does it use a UUID, if so try changing to the actual /dev/sdXN device name.

    1.) Deinstall rpm package kernel-default-extra (=> unsupported kernel modules).
    2.) Check your kernel "tainted state":

    # cat /proc/sys/kernel/tainted
    0

    # more /etc/modprobe.d/10-unsupported-modules.conf |grep -i -v ^#
    allow_unsupported_modules 0

    Modern hardware supports "UEFI Secure Boot". I recommend for security reasons the usage of "UEFI Secure Boot". For more information about "UEFI Secure Boot":

    Be aware that "UEFI Secure Boot" doesn't (yet) support Hibernation/hibernate. See comment 29:

    thanks for quick support.
    What is the consequence removing the kernel-default-extra?
    I need some software for work.

    I tried it, removed kernel.default.extra in package manager. Seems to work.
    Thanks for help

    Hi Malcolm, the unsupported Kernel was anyway not the reason.

    SWAP results are this:
    hans-christoph@linuxSLED:~> cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
    GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-uuid/e1659cee-7914-425d-b343-17172a04b02a splash=silent quiet showopts crashkernel=174M,high crashkernel=72M,low"

    I hope I can change it to device name:
    Size is: 17 Gb (I use SSD)
    name /dev/sda3

    What I can't understand is: The system boot up to login. The only what not happen is start the desktop. The system should be boot up complete?

    Yes, I use UEFI boot. I use SSD.

    see ...
    hans-christoph@linuxSLED:~> cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
    GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-uuid/e1659cee-7914-425d-b343-17172a04b02a splash=silent quiet showopts crashkernel=174M,high crashkernel=72M,low"

    Hi
    If as root user check the output from;

    Code:
    blkid
    Does the UUID correspond with your swap partition? Or you can change it to resume=/dev/sda3 in YaST bootloader, or via command line and rebuild grub.

    Hi Malcolm, thanks for support.

    Code:
    linuxSLED:/home/hans-christoph # blkid
    /dev/sda2: UUID="ef477c07-44f4-4f7b-a864-2e3db8ab1da5" UUID_SUB="4beb56de-ab60-493f-a58d-fbfaa80d71e1" TYPE="btrfs" PARTUUID="9b3964d6-99a7-4709-b03b-d74b5616e956"
    /dev/sda1: SEC_TYPE="msdos" UUID="1134-FED2" TYPE="vfat" PARTUUID="64ed5ad8-cd97-44e6-9bf8-5d34bdaa60a5"
    /dev/sda3: UUID="e1659cee-7914-425d-b343-17172a04b02a" TYPE="swap" PARTUUID="6960820f-3102-4297-8deb-bbedb9bc3238"
    /dev/sda4: UUID="32d4acc6-dff1-44fc-87f1-078867c6bc18" TYPE="xfs" PARTUUID="0cba231d-53e0-4b24-b2eb-56ecc1e52bab"
    linuxSLED:/home/hans-christoph #
    This number I found in DISKS as well for Swap:
    UUID="e1659cee-7914-425d-b343-17172a04b02a"

    My impression is X-Windows doesn't start. I had that before.
