IzZy's questions

I started to trying optymalize my boot time. When I put command systemd-analyze plot >bootup.svg, I saw that swap.target continues for more than 1 min. So what can I do with that?

EDIT:

grep swap /etc/fstab output:

# swap was on /dev/sda4 during installation
UUID=6b06a63a-e66b-489c-834d-04b5ab909160 none            swap    sw              0       0

sudo blkid | grep swap output:

/dev/sda4: UUID="8fb26a5f-62fc-4c3a-8df5-421f884844b7" TYPE="swap" PARTUUID="d9fa2484-04"

'dmesg' part of output:

I know that there was many similar topics but I haven't find answer yet. On my Ubuntu, sd cards are everytime read only, I can't write on it or format. I can do everything on other devices (Android, Windows). When I try to format it on gparted, I get following error:

error checking file system on /dev/mmcblk0p1: error when trying to detect filesystem on'/dev/mmcblk0p1': Failed to open device '/dev/mmcblk0p1' (udisks-error-quark, 0)

I tried 'sudo hdparm -r0 /dev/mmcblk0' but without succes. Any ideas?

EDIT: I can make this:

sudo hdparm -r0 /dev/mmcblk0p1
sudo mount -o remount,rw /dev/mmcblk1 /media/adrian/1C14-3325/

Then I can write and delete on disk, but I have to repeat this everytime I unmount card and still no possibility to format or use dd command.
