good day
from time to time i install eos on a new notebook: or better said on another notebook - (all those notebooks i own - they are not new… ) today i have got a
want to create a swap-temp on my enedavour-os that is installed on a old thinkpad T520
well i guess it is clever to create a swap-file here:
i did this once before: how to proeceed
btw: i try to show hw info of the notebook - with the following
Displaying Detailed Hardware Information
Here we will describe the commands, other than uname, that are used to extract detailed hardware information of your system:
Get Hardware Information with lshw
The lshw utility lets you fetch important hardware information, such as memory, CPU, disks, etc., from your system. Please run the following command as a super user to view this information:
and the command
$ sudo lshw```
but this does not work on endeavour at all
anyway: i have tried to create a swap-file . but see how and where it ended up:
dd if=/dev/zero of=/1G.swap bs=10M count=100 status=progress
mkswap /1G.swap
swapon /1G.swap
echo “/1G.swap none swap sw,auto 0 0” >> /etc/fstab
- see what i have got back:
$ dd if=/dev/zero of=/1G.swap bs=10M count=100 status=progress
dd: konnte ‘/1G.swap’ nicht öffnen: Keine Berechtigung

any ideas what is going wrong here - guess that the Lenovo ´T520 is quite tooo old - and does not contain too much hw - and especially memorey
what do you day!?
