Thread: Desktop Lag

  1. #1

    Default Desktop Lag

    Hey,
    During multitasking in desktop sometimes I experience lag even when just switching into different applications.
    Could this be due to my CPU?
    Currently running Intel Core i3-2100.
    RAM - 4ghz.
    Nvidia 550 Ti GTX
    Would running an AMD cpu fix the problem?

    Which Desktop are you running?
    With only 4GB, if the User is doing moderately heavy multi-tasking I generally recommend a lighter Desktop like LXDE or XFCE.

    If you want to add another Desktop to what you already have installed, just "zypper install nameofdesktop" for example the following
    Code:
    zypper install lxde
    Then, go to YAST > /etc/sysconfig editor, and disable auto-login (assuming you have it enabled)
    - search login
    - select auto-login
    - remove any name displayed and leave the field blank
    - Save your settings

    Then, reboot.
    When the screen displays to enter your Username/Password, you'll also see selections for various other options including your desired Desktop.

    HTH,

    Well then again I'm fine with Plasma 5 desktop for KDE.
    As far as hardware, which cpu is more suitable for Linux openSUSE Intel or AMD?
    Is it the same thing within the processors or is there a difference?

    Besides using another desktop is there a way to use tweaks with in the operating system to reduce lag?

    Check if your system is swapping. But with 4GB (if that 4hgz is a typo?) and "normal" usage, that should not rea;y happen.

    Several possibilities.

    You could e.g. run
    Code:
    top
    There is a heading line there about swap. Look at the 'used' item (it is 0 at my system at the moment, only having 2GB of memeory, on openSUSE 31.1 and 1 KDE user active).

    Or
    Code:
    /usr/sbin/swapon -s
    which also has a usage column.

    One of the machines (notebook) i use with openSUSE 42.1 x86_64 and KDE (Plasma 5.4.3) is based on an Intel Core2 Duo T9400 @2.53GHz and 4 GB memory. With just one KDE user and /tmp and browser cache placed in memory still 2.29GB of RAM and 100% of SWAP are unused. And i can see no desktop lag
    although the system performs not as fast as my desktop system (Intel 4790K with 32GB memory) does .

    Currently i do not have any systems with AMD CPUs so i can't tell whether they would give an even better performance.

    Best regards

    Should not matter about brand of CPU the clock speed and number of cores is what is most important. I prefer AMD but that is just a personal choice and my current CPU is a AMD black addition 6core I choose it basically because it had no GPU I hate CPU's with on-board GPU. It is was because I add a good GPU anyway and a on-board GPU is just a waste.
