Thread: system crash

  1. #1

    Default system crash

    Switching from xp (that has worked fine) to Linux got me into a major trouble: First, I installed Ubuntu that didn't reboot. After a forced rebooting, it failed to recognize the CD-ROM. I installed then openSUSE that worked fine, except the broadcom wireless (and NDIVIA graphic) card. Several attempts to configure the wireless failed and the reboot problem returned. So I tried to reinstall openSUSE, but the installation broke down and now the system wouldn't boot at all. I got the "grub rescue>" prompt. "ls" provides (hd0) (hd0, msdos1, 2, 3 and 5) (hd1) (hd1,msdos1, 2, and 3), but insmod with anything I tried provides only "unknown filesystem". How can I resuscitate the system, wipe clean the hard drive and install the OS anew? I am new to Linux, so if you can help, please by step-by-step instructions.

    Just boot the installation media, and when it asks where to install,
    tell it to use the entire disk - assuming that you do not have anything
    at all on that disk that you want to keep.

    If you do want to keep things, well, then we will need details of what
    you have, what you can destroy, what you want to destroy - based on the
    output of "fdisk -l" from a Linux live system.


    Mind: there is the possibility that your hard disk is old and has bad
    sectors. This would be bad news.

    Carlos, unfortunately, I cannot boot: Interrupting the boot process by F1 gives me 3 boot options: From SATA0, SATA3, or onboard or USB CD-ROM (as I have 2 hard drives). The last one, however, gives an error message: "selected boot device is not available, strike F1 to retry, F2 to setup and F5 to debug." I ran into he same problem when I tried re-installing Ubuntu, but I was still able to access the CD-ROM and install the OS with the openSUSE DVD in the drive. Now I have the same problem with openSUSE and booting from the HD gives me the grub prompt. Thanks, M

    If you can not boot from external media, there is very little that can
    be done.

    If your machine is recent enough, it can boot from USB sticks, and that
    is the preferred option. You can create a boot stick using the
    downloaded openSUSE image using the instructions at

    http://software.opensuse.org/131/en
    https://en.opensuse.org/SDBownload_help
    https://en.opensuse.org/SDB:Live_USB_stick

    Carlos, I have no idea what happened, but I was able to reinstall openSUSE 13.1 from the dvd (i.e., I didn't need the stick). Now I am concerned not to screw it up again, as the reboot problem and the crash was due to monkeying around with the wireless without understanding what I was doing. At this point I need advise how to get my broadcom 43222 and the NVIDIA G98 [GeForce 9300 GE] cards working. The latter is for the dual display that the system apparently recognizes, but is not working, as I guess the driver is missing. M

    Ok, each are different questions that must be asked separately :-)

    First, there is a wireless network forum here, with a few stickies. You
    have to read them, apply, and in doubt, ask in that forum. I think the
    stickies or faqs tell you what information they need.

    If you don't have it clear, ask them :-)


    And, about the video, well, there is a wiki page at openSUSE that
    explain an "easy" way and a "hard" way:

    http://en.opensuse.org/SDB:NVIDIA

    I use the easy way. Basically, you add the nvidia repo from the list of
    community repos in yast, and it automatically adds the appropriate
    packages if your card is on the list.

    Again, if you don't understand the doc, ask, but in the install-login
    subforum here.

    Each time give your question an appropriate tittle so that the people
    that know about that subject can easily find it and help you.

    I resolved both, the wireless and the graphic driver problem. With the system now up and running, I have the problem of software installations. In particular, after a few failed installations, the system slowed down noticeably. Any suggestion how to troubleshoot the problem? Maybe I started background processes that should be killed permanently. How can I identify and remove them?

    Well... Typical candidates are:

    A process taking a lot of cpu. This can be found, for example, by
    running "top" in a terminal. The busiest processes are at the top of the
    list, with the percent of cpu they use.

    Another candidate is a process not taking a lot of cpu, but crawling the
    disk to find out what you have stored in there, so that you can later
    quickly search for files either by name or by content. These are more
    difficult to locate. I'm sleepy now, I don't remember if there is an app
    to find them out easily.

    Another one could be that the graphics are complex to draw and you are
    not using the proprietary nvidia driver. Worst case would be that you
    were using the framebuffer or vesa fallbacks.

    In any case, it is usually best to start a new thread specifying in the
    title that your system is too slow.

    Carlos, this is part of the learning curve: The sluggishness turned out to be the result of replacing my Dell wired mouse by a Logitech wireless one. It has never been a problem with Windows. Do I need a keyboard/mouse driver for Linux? How about bluetooth keyboard/mouse? Thanks, M

    Ugh. I would stay away of anything bluetooth in 13.1, for the moment.

    KDE is broken regarding bluetooth on this release, and this is explained
    in the release notes. Today I learned that it is also broken on XFCE
    (and the release notes say nothing about this). It works in Gnome, they say.

    I have never used bluetooth mouse or keyboards, so I can not guide you
    on how to use them.
