xinput:


if your input from the trackpoint is too slow on linux, you could try to modifiy your mouse.pointer.matrix.

with xinput set-prop dev-id option-id x 0 0 0 x 0 0 0 1 where x is your variable.


xinput list-props 14
Device 'PS/2 Generic Mouse':

Coordinate Transformation Matrix (191):	
xinput set-prop 14 191 2 0 1 0 2 0 0 0 1


while missing the button 3 is solved by emulating the 3d button with the 2 one, youre still missing the 3rd:

libinput Middle Emulation Enabled (362):
xinput set-prop 14 362 1



startup .xsessionrc


this setup has flaws, in unpredicible behavior,...

lvmresizepart:



resize of 2 partitions with lvm on debian 12, on a running system-

the job was to free more space for the root partition.
so, i was shrinking the home and extended the root.

home was 897G
root was 28G

20G Volume got resized.

first, B a CK UP!


umount /home

e2fsck -f /dev/mapper/zmw--server02--vg-home 

resize2fs /dev/mapper/zmw--server02--vg-home 877G (that is -20G)

lvresize -L 877G /dev/mapper/zmw--server02--vg-home

lvdisplay

lvextend -l +100%FREE /dev/mapper/zmw--server02--vg-root

resize2fs -p /dev/mapper/zmw--server02--vg-root

df -h

+
it run very smooth. the lvm seems to be very reliable.
