Debian linux mint, resume after hibernation fails

0

When your hibernated session fails to resume, most of the time your resume partition is wrongly configured in initramfs.

cat /etc/fstab and look for a line like:
# /dev/sda7
UUID=3a3ee660-d330-4c36-847e-54fe39f1d45c swap swap sw 0 0

edit /etc/iniramfs-tools/conf.d/resume
Make sure you have the correct uid;
RESUME=UUID=3a3ee660-d330-4c36-847e-54fe39f1d45c

And update your initramfs;
sudo update-initramfs -u

Done.

0

At this moment the edgescrolling and tap on the touchpad in Linux Debian Mint is disabled.

To enable it you must edit /usr/share/X11/xorg.conf.d/50-synaptics.conf and add

Option “VertEdgeScroll” “true”
Option “TapButton1” “true”

Logout and log back in again to reload xorg.

IF you need to encode parts of a POST url:
SUM=$(md5sum $APPNAME.tar.gz.gpg 1> /dev/null)
SUMENC=$(echo $SUM’ /*$$[]’ | perl -MURI::Escape -lne ‘print uri_escape($_)’)

Resize an ext4 partition manually.

0

As gparted doesn’t seem to support ext4 you should resize your partition manually.
It sounds difficult but is trivial.
First delete the partition with fdisk, then recreate it again in the desired size, resize the filesystem, done.

In some more detail, assuming the partition is /dev/sdb3

umount /dev/sdb3

sudo fdisk /dev/sdb
(remove sdb3)
(recreate sdb3 with the same start position as the previous one)

resize2fs /dev/sdb3 (when no size given the whole partition is used)

mount /dev/sdb3

That’s it.
