    But you are doing that during the copy.

    The idea is that you run the copy in that terminal. I'd use 'mc',
    midnight commander.


    If what you mean is that the terminal is sluggish even before you start
    the copy job... well, that's bad.

    Oh right sorry my mistake. Let me go try.

    Okay so I ran cp from tty on the centos full dvd iso file and tried
    copying it from my 1TB drive to my SSD. When I went back to the GUI it
    was very laggy as normal BUT when I went back to tty I could do
    everything fine (aka input and output seem fine). I tested this by doing
    ls -R on my home directory.

    I forgot to mention that you have 6 text terminals available, from
    [Ctrl][Alt][F1] to [Ctrl][Alt][F6]. So you can run the copy in one
    terminal and do other things in the rest.

    Ahhh, that's what I feared. The terminal is not affected, it is KDE
    which is affected. I could theorize on the reasons, but I really do not
    know why.

    Hey, what you tried, a recursive directory listing is i/o intensive, so
    that was a good test.


    Well, you can try something else: try different desktops. XFCE needs
    installing the pattern, but there is a plain desktop that I think it is
    always installed on all machines; I don't remember the name. You could
    try that - when you can exit KDE, of course.

    The idea is to pinpoint if only KDE is affected by this or not, and then
    all you people affected by this issue can report in a Bugzilla.

    I think you are talking about IceWM and I just went to try it and it
    seems to be fine. I also have Gnome 3 installed so I tried in there too
    and it seems that there is no lag at all. I was able to do ls -R and
    spam paint in GIMP at the same time. Seems you are probably right, it
    looks like a KDE issue. I will be happy to report it if someone else
    using kde who experiences this can confirm that it does not happen in
    IceWM and tty.

    Sorry for double posting

    After some further testing in KDE I cant seem to reproduce my problem
    with the file copy (even tried a 7GB file). This is making me think it
    is either not KDE at all or it is something within that is triggering
    this problem in certain situations.

    I tried copying a 3.1 Gb iso in IceWM, but the behavior is the same, maybe not as bad as in KDE, but highly noticeable. I also tried copying on the same machine, but on Windows 8, but files are being copied with no problem whatsoever.

    Where can we report this issue? Because it's becoming frustrating!
    I transfer a lot of things, quite often & i don't want to switch to another distro just because of this.

    Offtopic:

    Does anyone know how to enable bluetooth on the HP Compaq 6910p ? I can't seem to find it in hardware information and bluedevil doesn't detect it.

    .
    There is guidance here on raising bug reports on openSUSE : http://en.opensuse.org/openSUSE:Submitting_bug_reports

    You can raise a bug report on openSUSE-13.1 if not done so already.

    You can use your openSUSE forum user name and password when logging on to bugzilla.
