  • Thanks, I didn’t know that x8 pcie was a thing now… also resizable bar support – something else to research.

    I cleaned up the dust and I haven’t noticed those “jerky cursor” problems for a bit, so hopefully that was it. It wasn’t even that much dust, so we’ll see how long 'til the system does it again. I am not trying to play any specific games, just trying to use the OS, file picker, etc., without lag.

    The PSU is a Corsair TX750

    I would like a linux desktop that “just works” ™ when I upgrade, but doesn’t have to play heavy games or pull heavy workloads. I thought a steam machine might be a decent choice for that, but hopefully this desktop has a few more years left in it.






  • Thank you for the link to explaining computers – I’ll check it out!

    For motherboard, it appears to be this Gigabyte . I found this command online: dmidecode

    $ sudo dmidecode -t 2  
    # dmidecode 3.5

    I will try to figure out the PSU soon. EDIT: Corsair TX750


  • Thanks, that would probably attract attention lol. I was looking at System Monitor when the stuttering happens and I didn’t see a big CPU spike, but I am at a loss.

    EDIT:


  • It doesn’t struggle with web browsing per se., just with opening and closing windows mostly. I just experienced it – I open the file browser, the system hangs for a moment or two where I can’t move the mouse. Then the mouse jerks around for a bit. Then the system is smooth again. I looked in System Monitor right after this happened and didn’t see any big spikes in storage, CPU, or memory, so I am assuming GPU.

    It is probably not physically clean. I should address that first.

    It is running on a Samsung SSD 830 series. I tried enabling write cache. I ran into the system stuttering problem (described above) clicking ‘cancel’ on a random dialog.

    I have had a lot of problems with codecs, and video playback being choppy everywhere, which is why I am focused on getting good hardware codecs that are supported under linux.

    The CPU/motherboard definitely does have a built-in iGPU. I think I could try it out with prime-select. Maybe that is worth experimenting.
