    When I built a 5.3 kernel a week or so ago and it was lousy on this Thinkpad.
    Slower to boot and double the usual RAM usage, so I went back to 5.2.15.

    Just curious which Thinkpad was that…
    On my part I have so far tested 5.3.14 kernel on two Thinkpads: T410 and X61, with antiX Live encrypted. My subjective impression was that it did not seem slower than the default 4.9 on these Thinkpads. Also memory usage did not seem significantly higher if at all. I did not scientifically benchmark however…
    I am curious of experience of usage on other machines…

    Additionally: I did not detect any issues with 5.3.14 so far except Conky does not show WiFi part anymore on Thinkpad X61. It does on T410. Minor issue as Connman still connects.

    Additionally: I did not detect any issues with 5.3.14 so far except Conky does not show WiFi part anymore on Thinkpad X61. It does on T410. Minor issue as Connman still connects.

    Then you should check on the x61 what the Wifi interface is called:
    inxi -nxxx
    and correct this in the .conkyrc accordingly.

    This is py_mem.py for 5.2.21

    Thanks much for memory usage report…
    Mine was only a subjective impression, not supported by any measurement. Thinkpad L412 is equivalent to my T410, same processor at least.
    Now I would like to run this py_mem.py script across my laptops to see how much higher memory will kernel 5.3.14 demand… Perhaps someone can kindly help me find this useful memory utility, please…
    I did install antix-goodies-core, which is supposed to have this py_mem.py but when I am looking in /usr/local/bin it seems nowhere to be found. And how exactly to execute to get accurate measurement of memory use. I believe this would from terminal when nothing else is running or still better to run automatically at startup so measurements would be most accurate?
    I apologize this is a very basic question which I should know

    Sorry, my typo – it is ps_mem.py
    In my test, as soon as I get to desktop, I open terminal (urxvt) and su to root and type ps_mem.py

    Thanks much. I was mistaken then that it was still another one for memory measurement…

    Update: Interesting… In my case it is also reporting exactly twice higher memory use for 5.3.14 than 4.9: 345 M vs. 172 M… Mem use in Conky is about the same though…
    What makes me wonder though is that mem use reported through ps_mem is exactly double between these kernels. I would rather expect more random increase, such as e.g. 56% or 84%. So curious whether exact double mem reporting is some misinterpretation of this utility resulting from new kernel…

    Thanks. I will check .conkyrc shortly… However I am not sure why this would be happening. The same Live USB booted on one laptop shows Conky reporting WiFi and on another it does not. The same network SSID. It seems to have started happening after kernel update…
    Whatever the reason, WiFi continues to connect normally, just does not show in Conky…

    Thanks again for the tip male. Indeed .conkyrc did not have the right wlan interface. For some reason the interface name is wlan2 on this laptop while conky had wlan0 and wlan1 only…
