Is there any specific tool for monitor CPU temperature?

save this code to some script and make it executable.

1. #!/bin/bash
   
2. Color_Off='\033[0m'        
   
3. Red='\033[1;91m'
   
4. while :
   
5. do
   
6.         clear
   
7.         T1=`cat /sys/devices/virtual/hwmon/hwmon1/temp1_input`
   
8.         T2=`cat /sys/devices/virtual/hwmon/hwmon1/temp1_crit`
   
9.         echo "――——―――———―――———"
   
10.         if [ "$T1" -gt "$T2" ]
    
11.         then
    
12.                 echo -e "CPU temp: ${Red}"$T1"${Color_Off}"
    
13.         else
    
14.                 echo "CPU temp:" $T1
    
15.         fi
    
16.         echo "CPU freq: `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq`"
    
17.         echo "――——―――———―――———"
    
18.         sleep 1
    
19. done

I've created a small minecraft server and after having stopped the server, kswapd0 takes 100% in my ...

I Create Swap also like this way with "sysctl vm.swappiness=0"
but nothing work. kswapd0 still running 100% after low Memory.

Only the Workaround with "echo 1 > /proc/sys/vm/drop_caches" works.

I have tried (RAID 0 - striping). It works, but to create or assembly raid
you need also compile kernel modules (because loboris images kernel doesn't support it),
for example raid0.ko for RAID 0 - striping.

Hi!
I'm trying to use a wifi dongle based on rt2870 using Ubuntu 15.10 image:

[   20.036549] phyla -> rt2x00lib_request_firmware: Error - Failed to request Firmware ('rt2870.bin').

I've put the requested firmware inside /lib/firmware but the kernel module but it fails to REQUEST the file... On my laptop is working flawlessy...

Is there some bugs in udev or the firmware requesting procedure? thanks

This was already answered couple of days before.
For now, firmware loading only works on Ubuntu 14.04 (Trusty) and Debian (unconfirmed).
Unfortunately, the search function does not work on this forum, you have to search manualy.

You have to give more detailes if you want help (does it works when you start it manualy, what exactly is the problem with rc.local, ...)
