Ubuntu: new system command for today

Check mainboard status

ptantiku@ptantiku-desktop:~$ acpi


Battery 0: Full, 100%
ptantiku@ptantiku-desktop:~$ acpi -V
Battery 0: Full, 100%
Battery 0: design capacity 5200 mAh, last full capacity 4089 mAh = 78%
Adapter 0: on-line
Thermal 0: ok, 34.5 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 89.0 degrees C
Cooling 0: LCD 0 of 7
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10

Check CPU info

ptantiku@ptantiku-desktop:~$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model  : 23
model name : Intel(R) Core(TM)2 Duo CPU     T8300  @ 2.40GHz
stepping : 6
cpu MHz  : 800.000
cache size : 3072 KB
...

Checking CPU Speed + Available speed (change cpu0 to cpu1 for another core)

ptantiku@ptantiku-desktop:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 
2400000
ptantiku@ptantiku-desktop:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq 
800000
ptantiku@ptantiku-desktop:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq 
2401000
ptantiku@ptantiku-desktop:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 
2401000 2400000 2000000 1600000 1200000 800000
ptantiku@ptantiku-desktop:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold 
95

meaning?  my current CPU runs at 800MHz which is minimum speed it can go.
if CPU load reaches 95%, it'll scale up to max speed.


Checking GPU Temp:

ptantiku@ptantiku-desktop:~$ nvidia-smi -a
