Thread: File Manager crashes under SU

    Default File Manager crashes under SU

    I'm running Suse 11.0 v3.1.34 (kernel 2.6.25.5-1.1-default).

    I was literally just using file manager as SU this morning. Now it is crashing every time. I get to the point where I enter my password, then it crashes with the following message:

    The application konqueror crashed and caused the signal 11 (SIGSEGV):

    what were you using it for: moving, deleting, looking inside files?
    what? where?

    i notice this is your first post here....*welcome*...but, i wonder how
    much experience you have with openSUSE and/or Linux...

    and, i wonder what you moved, deleted or changed...

    mostly, i wonder if you put it all back like it was before you started
    doing whatever you did in the file manager as root if it wouldn't be
    alright again..

    I'm a Windows vet trying to learn Linux. I'm becoming familiar with more of the linux commands, but am still very slow at it so I tend to use the file manager. New to Suse and <6 months with Linux in general.

    We have installed some custom software which should have zero impact on any system (root) files. The most recent item that I installed (in order to get my software to run properly) was qwt-4.2.0. To the best of my knowledge, i haven't deleted or moved any important OS files.

    Does that help?

    maybe..

    i wonder, when you say you haven't moved or deleted any important OS
    files, does that mean you know which ones are important/unimportant?
    [i would recommend you consider every file outside of /home as
    important and don't change them in anyway (including moving) until you
    have a safe backup of the original AND a foolproof recovery (move
    back) plan...btw, i've used linux most of 10 years and i STILL do it
    that way]

    and, i wonder how you installed qwt-4.2.0, because that doesn't
    require the use of a file manager...(so, i still wonder what you were
    doing with a file manager with root powers??)

    have you yet discovered YaST or Zypper? they are the preferred (and
    safest) way to install programs...as far as i know the qwt you mention
    is available as an rpm and once you have it local just right click it,
    select Actions > Install with YaST, give the root pass and sit on your
    hands--no file manager required..

    [if you downloaded a tar and compiled that qwt then you are working
    under the broadly believed idea that installing linux software is
    'difficult'...which is FUD]

    if you have not yet you should read http://en.opensuse.org/Concepts
    especially the part about software handling..

    since we don't know what was munged i believe i'd begin by trying to
    repair konqueror and dolphin...do that in YaST:

    YaST > Software > Software Management > search for konqueror and in
    place on the right side where you see a blue check mark next to
    something related to konqueror, right click it change the symbol to
    "Update" which should put all the right stuff back in the right place..

    and, do the same (search, right click, etc) for dolphin..

    hopefully that will solve those problems..

    i guess there is an outside chance that something about the qwt you
    installed messes with the Qt the system uses...but, i have no idea..

    come back.

    I've just noticed that other programs are not working either (either under root or user). I tried configuring my network card under "Network Settings". When I try to open the settings window, the computer thinks for a bit I can see it trying to open the network settings panel and then nothing happens. Same goes for "Install Updates". Not sure if this is a separate problem?

    This is a brand new install on two brand new 1TB HDs, 1GB RAM, dual 2.8 GHz processor, on-board video card. I'm also noticing that it runs very slow: windows freezing up/laggy. I tried to edit xorg.conf as suggested by another post.

    Code:
    Option "AllowGLXWithComposite" "True"
    Option "DisableGLXRootClipping" "True"
    Option "RenderAccel" "True"
    Option "AddARGBGLXVisuals" "True"
    I don't notice much difference.

    Right, I have not touched anything outside of user directory unless asked to. Most of our software packages require root access to set variables and the like, so I just logged in as root - which is why I was in the file manager as root. I am not used to making backups of files I edit, and will learn to do so quickly! What is a good way to recognize which should be backed up without going overboard? Anything outside of user directories?

    I installed qwt under my user account with rpmbuild:

    Code:
    rpmbuild -ta qwt-4.2.0.tar.bz2
    It then asked me to do the following:
    Code:
    cd /usr/src/packages/RPMS/i586
    su
    rpm -ivh qwt-4.2.0-1.i586
    rpm -ivh qwt-devel-4.2.0-1.i586
    I didn't get any sort of errors.

    well...i guess that means you have been logging into KDE as root, huh?

    in my most humble opinion that is something which should never be
    done, ever....my experience is that that always leads to a wide (very
    wide) range of little problems that are so very difficult to track
    down that it often requires one to start over, fresh format and install...

    you can solicit other opinions (some say it is ok as long as you are
    careful---but i don't know how to be that careful)...now i know the
    model that MS used for years leads folks to come to Linux and wanna
    wander around as root...my best advice is don't do that....also, many
    MS vets don't like the idea that they can't do with _their_ machine
    what they want, and then are frustrated when they do as they wish and
    it all turns brown..

    here is some stuff you probably ought to take the time to read:

    http://docs.kde.org/stable/en/kdebas...uide/root.html
    http://en.opensuse.org/SDB:Login_as_root
    http://tinyurl.com/6ry6yd
    http://tinyurl.com/8b9s6

    you do as you wish...but, if you want stable (ROCK SOLID) then never
    ever log into KDE, Gnome or any other *nix desktop environment as
    root...and, never even open a file as root until you have a BACKUP
    copy of it untouched (just opening a file in a file manager as root
    can/will change file permissions..

    oh, and you will find plenty of advice to get around permission
    problems by using chown (or other) and "magic" codes like 777...do NOT
    do it, until you have a valid backup and recovery plan..

    did the network ever work?
    during initial install were you connected to the local network or
    thereby the internet? usually if you have an ethernet cable plugged in
    and select DCHP it "just works" (*nix was networking before Windows
    for Work Groups was 'innovated')

    i suggest you repair all the damage you have done as su/root and then
    revisit the network problem...

    another post here? or?
    i GUESS you installed KDE4? if so i highly recommend something else...
    kde4 is one huge pile of bugs until you get to kde4.3, at least

    and, all that "laggy" is more likely a slow graphics card, what kind
    of graphic chip are you using?

    as mentioned, don't do that...instead log in as yourself and 'become
    root' the correct way..

    well, any file you change outside of your home directory can kill the
    system, or some part of it..

    and, for that matter, any file you change in the hidden directories of
    the /home can kill or radically change the operation, looks etc of
    that user....well, remember this: Linux is born a MULTI-user
    environment....you can have hundreds of users and each user can use
    Firefox, and mess with the settings s/he wants to see and all of those
    will be saved in /home/[a user]/.mozilla, and that user can go into
    that directory and throughly screw it up and never be able to use
    Firefox again (until repaired) BUT all the other users on the system
    can still use Firefox....BECAUSE the program itself is outside the
    reach of ALL users, except root.

    well, i don't even know how you could have installed it into /home..

    i've never used rpmbuild, ever....if i down load a source tarball i
    unpack it and read the README which gives step by step instructions on
    how to compile and install....no need to go through the process of
    building an rpm..

    but FIRST: i always search with YaST to see if there isn't a package
    already in the openSUSE repos ready made for openSUSE..and just click
    install done!

    second, i'd look via http://software.opensuse.org/search, but i do NOT
    recommend the "one click" install...rather opt to download and right
    click Action > Install with YaST, as previously mentioned.

    then maybe you installed it ok....i wonder though why you use 4.2 when
    5.2 is available..

    Those system specs are for the computer I'm doing this install on. The graphics card is the generic, on-board card. i.e. no dedicated graphics card.

    WRT running the most current updates/software, I would love to be doing that. However, I am told by my higher ups (i.e. well-seasoned Linux users) that the software they've developed on old OS versions of linux will not properly compile on newer versions OR it is possible for our software to not work due to differences between, say, Suse 9 and Suse 11 or qt3 vs qt4, etc.

    As per the network problem, I think I have it sorted out. I managed to get yast2 working (again - did a "zypper rm" and "zypper in") and set everything up using the GUI. I have 2 cards, one for internet (DCHP) and one for local hardware (static). I was having troubles with the static one.

    Thanks for your comments and assistance.
