I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.



This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.



I marked the delay point with --delay--. Just roll down and you'll see it.

kde startup kubuntu plasma5

    I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.



    This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.



    I marked the delay point with --delay--. Just roll down and you'll see it.

      I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.



      This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.



      I marked the delay point with --delay--. Just roll down and you'll see it.

      kde startup kubuntu plasma5







      share|improve this question
















      I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.



      This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.



      I marked the delay point with --delay--. Just roll down and you'll see it.
