    Angry System constantly runs so slow

    I thought it was maybe a problem with not enough RAM, but from responses I got here in Hardware section, it seems that is not the problem. Doubt that it's over heating, in BIOS the temperature readouts are 32*C CPU and 17*C system. Using lmsensors I get readouts of 0*C CPU and -10*C GPU, which is obviously NOT correct.
    I currently have the open source video driver, heard lots of other people saying that the fglrx driver causes the system to not boot into gui or not boot at all.
    Is the whole problem due to graphics driver? Or something else?

    The machine is a CybertronPC Assault A46 (got mine from Best Buy)
    http://www.amazon.com/CybertronPC-As.../dp/B00NC07BTI

    Here is the hardware it's running

    Mobo (has latest revision BIOS v32.7)
    http://www.newegg.com/Product/Produc...82E16813130762

    APU (I'm looking into upgrading it to an A8 or maybe an A10 unlocked)
    http://www.newegg.com/Product/Produc...82E16819113349

    PSU (the stock one was what is included with the case, cheap 350 watt junk with no over volt, over current or active PFC)
    http://www.newegg.com/Product/Produc...82E16817703013

    HDD (KInfoCenter shows it as IDE bus)
    http://www.newegg.com/Product/Produc...82E16822149380

    SSD (not currently installed or in use, will take a performance hit from mobo having only SATA II ports, have to learn how to install for SSD as boot and HDD for storage.. and noticing this shows as 256GB, mine is 128GB)
    http://www.newegg.com/Product/Produc...82E16820227791

    RAM (I'm planning to upgrade this to 2x 8GB DDR3-1866.. been looking at G.Skill and HyperX)
    http://www.crucial.com/usa/en/ct51264ba160b

    At boot up and during reboot I see the following message show on my screen.


    In case it's hard to see it says
    [firmware bug]: AMD-Vi: IOAPIC[0] not in IVRS table
    [firmware bug]: AMD-Vi: No southbridge IOAPIC found
    AMD-Vi: Disabling interrupt remapping

    I ditched the stock CPU cooler that came on it (tiny aluminum) for a stock PhenomII X6 cooler (copper base, aluminum fins and copper heat pipes). Thermal compound was all dried up and full of dust buildup, it now has fresh Arctic Silver 5 compound.

    in a console/Konsole run top and see if some process is eating the CPU. That also will show if all cores are working

    did you install the ati propitiatory drivers (I'm not sure if they work with build-in and gpu's they should)
    unlike intel's build-in gpu which is supported nativly by the Linux Kernel amd's are not see this page

    no I have not installed amd/ati proprietary driver
    in KInfoCenter I can see for Graphical Information - OpenGL it lists 3D accelerator 'unknown' and Renderer as 'Gallium 0.4 on AMD ARUBA'
    OpenGL/ES version 3.0 Mesa 10.3.7

    the worst seems to be with anything that is flash based (firefox won't even display, chromium is the only browser I can really use, chrome wouldn't even install).. while any flash content loads the screen just shows blank background and I have to minimize the browser then restore it for anything to even show up. network shows a downspeed of 1.8MB/s (I guess that is the max speed I can get on this N300 wireless adapter?), it's almost as if the CPU is pausing momentarily every few seconds or so.

    Here's what I see for readout of 'top'
    no idea what half of that is or if it should even be there.

    Apparently AMD has a problem.

    This Ubuntu Forums solution should apply here as well, with modifications for openSUSE
    http://ubuntuforums.org/showthread.php?t=2254677

    Open the following file in your text editor of choice
    Code:
     /etc/default/grub
    Find the line "GRUB_CMDLINE_LINUX_DEFAULT="
    and edit it as follows
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivrs_ioapic[7]=00:14.0 ivrs_ioapic[8]=00:00.1"


    After editing and saving your changes above, run the following to update your grub
    Code:
    grub2-mkconfig -o /boot/grub2/grub.cfg
    Now you can reboot to test whether your new grub resolves the errors you've seen.

    it won't let me save the edit to that file, gives an error saying that I either don't have permission to write or the disk is out of space

    You can edit that with Yast2-bootloader in > Kernel Parameters > Optional Kernel Command Line Parameter
    or by editing the file with superuser rights, like opening a terminal and typing:
    Code:
    su -
    <root password>
    nano /etc/default/grub
    edit as required, then Ctrl+O, <Enter>, Ctrl+X.
    You might have to install "nano" or use your favourite editor if you can't do that.
    Then refresh grub as written by tsu2.

    OK, made the change via Yast2-bootloader
    updated the grub as tsu2 said
    rebooted machine (that was the longest reboot I've ever seen since an old Intel Pentium machine)

    it still shows the same bug problem and everything still seems to be crawling like a snail... it still keeps flashing the HDD activity LED almost non stop as well.

    in a console run top and see what process is eating the cpu cycles. perhaps it is the indexer it can take time to index things and can use a large amount of resources.

    I had already posted before the readout of top. It hasn't changed any. From what I see 8.357% is the highest CPU use. Should there really be such a huge gap of nothing like that between where I put in the command and it actually starts outputting info?
    I think they just make hardware and software far too complicated and they should try simplifying it.
