• XPS 13 on Gnome DE - Slow and Laggy

    Hello Everyone,

    I have a Dell XPS 13 with the following specs:

    Intel Core i5-6200U (Skylake)
    8GB Memory
    256GB SSD

    I am running Antergos with the Gnome DE. For some reason, after I’m booted into my system and have my usual apps open (Chromium, Spotify, Terminal, etc.) it seems like my system gets really laggy after 10-20 mins. I know there is a memory leak on Gnome 3.28.x version currently, but not sure if this is connected to that or not.

    Is there any way I can do some profiling or see what is actually going on underneath the hood per se easily? I know I can run TOP, but looking to see if there is a better way to identify maybe what is actually slowing down my system.

    Thanks in advance to everyone for your time and help. It is greatly appreciated!

    htop shows the memory and swap usage quite clearly. Also glances is good for doing about the same.

    Use the tool right after boot, and later when the system is slow. Then compare the results, hopefully you’ll find the reason.

    If you have Gnome extensions, one or some of them may be the reason, too.

    I use Xfce, and have never noticed any slowing down.

  • watching the live journal can be helpfull too:
    journalctl -f

  • Hey Everyone,

    Attaching some HTOP screenshots to help in the troubleshooting. More details below:

    Image 1 - Fresh Boot (6 minute uptime):

    Image 2 - 12 Hour uptime:

    Image 3 - 1 day and 12 Hour uptime:

    These are with my usual applications open. I can see chromium taking up a lot of memory, but not sure if anything else jumps out at anyone. Thoughts?

    Thanks again everyone for your time ad help, it is super appreciated!

  • @a4orce84
    What if you try to reduce a program or its extension one by one, does the lagging stop at some point?

    For example, Gnome extensions may be candidates to try that.

    Another is chromium extensions, like PepperFlash. And if you don’t really need Flash, just remove it for good.

  • Thanks @manuel, I’ll give that a shot. But with my previous question, is there anything in the htop command that jumps out as a potential memory hog application or process?

    Thanks again for everyones time and help, it is greatly appreciated!

  • @a4orce84
    Not very much, only chromium as you already mentioned. But chromium’s memory consumption doesn’t seem extraordinarily high.
    You do have some swap usage (still not alarming amounts), but can you somehow see what’s causing it?

    Maybe show the output of

    lsblk -fm

    Also the journalctl what Joe suggested might show you some useful info.

    lsblk -fm

    Output of the lsblk -fm command below:

    Please let me know if I can provide anything else to help in the troubleshooting process.

  • @a4orce84 I would also suggest sorting by memory with the a descending order, so the highest memory using applications are on top.

  • I can’t see anything special with those outputs. Maybe @n_mag’s suggestion brings some more light.

  • top -o %MEM

    top -o %MEM


    Please let me know your thoughts! Thanks again everyone!

    From Judd’s links it may be a problem with the latest kernel.
    If that is the case here, you could try changing the kernel to LTS kernel (if you are using the default kernel). Don’t know if that helps though, since someone said that the same modifications were done to LTS kernel, too. But worth a try I think.

    To install LTS linux:

    sudo pacman -S linux-lts  # and optionally linux-lts-headers

    and reboot to the lts kernel (in the boot submenus).
