Linux

• https://0x.tools/ 0x.tools (GitHub) is a set of open-source utilities for analyzing application performance on Linux. It has a goal of deployment simplicity and minimal dependencies, to reduce friction of systematic troubleshooting. No need to install kernel modules or heavy monitoring frameworks. 0x.tools allow you to measure individual thread level activity, like executed code, sleep states, system calls and wait locations - by tracking (not tracing) and then sampling the right events at the right time.

• veraltete Snaps löschen:

  for i in $(snap list --all | grep deaktiviert$ | tr -s " " | cut -d " " -f 1,3); do OLDIFS=$IFS; IFS=" "; set -- $i; name=$1; rev=$2; echo snap remove --revision=$rev $name; IFS=$OLDIFS; done

cat /sys/power/mem_sleep
cat /sys/power/state

Wenn die Ausgabe

s2idle [deep]
freeze mem disk

ist dann kann man probieren:

sudo echo s2idle > /sys/power/mem_sleep
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=s2idle"
sudo update-grub
