    System hibernates during startup

    Hello,

    I already had good experince with lubuntu in virtual machines but am having a little trouble on my 1st physical installation:

    Asus Aspire One S150 (AtomN280; 1GB RAM)

    I installed the current Lubuntu Image from USB (18.04.3 LTS) with standard installer (no advanced Settings) and it went all good. Lubuntu boots but:

    When I power on the Netbook, it shows the boot-splash screen of lubuntu and then goes into hibernate-mode. After a few seconds I wake it up by any keyboard key and it continues to boot until the login screen. After entering my creds, it hibernates again. Waking it up again by keyboard key I am on my desktop. From now on everything is fine.

    Has anyone an idea, how this behavior is caused and how to stop it?

    Thx in advance

    Hold down Shift while booting to get to grub. Hit 'e' and replace "quiet splash" with "nomodeset". Ctrl+x to boot.

    Re: System hibernates during startup

    Rather than looking for clues in boot messages as @milesweb has indicated (during boot), I'd just scan `dmesg` for clues, next I'd also scan `journalctl`..

    I suspect it sleeps rather than hibernates (hibernate requires a power-key to be pressed in my experience, and not a keystroke)

    Since `dmesg` only contains boot messages (since cold-boot), I'd look for something like the following found in my journalctl for a recent 'sleep', then start looking backwards for clues..

    Code:
    Oct 15 00:31:21 d960-ubu2 systemd[1]: Reached target Sleep.
    Oct 15 00:31:21 d960-ubu2 systemd[1]: Starting Suspend...
    I don't know what caused it, but I'd hope to find clues in `dmesg` or `journalctl`, or at least clues on where I'd look next.

    Thx for your hints. I copied the dmesg log and found a few entries about 'sleep' - but have no clue where to look next:
