Thread: openSUSE LEAP 42.3 KDE - Oyranos-compat-gnome segfault entry in dmesg

    Default openSUSE LEAP 42.3 KDE - Oyranos-compat-gnome segfault entry in dmesg

    Hi all,

    I'm requesting help regarding a clean install of openSUSE LEAP 42.3 KDE in which I installed kolor-manager so that my monitor can properly utilize its colour profile. kolor-manager has various Oyranos dependancies and one of them is causing a segfault message in dmesg:

    Code:
    [   59.037179] oyranos-compat-[2283]: segfault at 0 ip           (null) sp 00007fff794fc678 error 14 in oyranos-compat-gnome[400000+3000]
    The colour correction is working properly and everything else seems to work but I'd also like to find out the cause of the segfault.

    Thanks in advance.

    Hi all,

    Thought I would reply with what I think is a better solution. Instead of kolor-manager,
    Code:
    zypper install colord-kde
    this will place a module in System Settings > Hardware > Color Corrections where you can load your profile. You can also install, if you wish, gnome-color-manager which will let you calibrate your monitor if you have an appropriate calibration device.

    As an aside, I think this should be included in the default openSUSE LEAP KDE install, then it would have the same "out of box" monitor color calibration as the Gnome desktop but now I know and maybe this will help some other people.

    Cheers.

    "kolor-manager" is a KDE4 Plasma application -- with a normal user's CLI use "zypper info --requires kolor-manager" to notice that "kdebase4-runtime >= 4.14.0" is required.
    • "kolor-manager" is **not** a KDE Plasma 5 (KF5) application . . .


    Yes, "colord-kde" (the KDE front end to "colord") is a KF5 application -- "requires": 'libKF5Service.so.5()(64bit)' for example.

    Thanks for the hint: I was about to re-investigate the KDE Colour Management world for KF5 -- up until now I've been manually adjusting the colour balance in the System Settings "Monitor Gamma settings".

    My requirements do not list "kdebase4-runtime >= 4.14.0". Strange. Maybe I'm reading this wrong?

    No, you read it correctly.
    dcurtisfra is wrong, kolormanager has been ported to Qt5/KF5 in 42.3.

    That's unrelated to the crash (of oyranos-compat-gnome) anyway though, which you can just ignore (if everything is working) I suppose.

    Oh! I was inspecting "kolor-manager" from this Leap 42.2 system plus the openSUSE Software URLs -- missed that the version change from 1.0.2 to 1.1.0 included the KF5 port.

    Whoever does things, occasionally breaks something . . .

    I've been having some problems with KDE5 colour management on 42.2. I use displaycal for calibration and found that after I installed it and oyranus that displaycalc was timing out when it informed the kde management about a new profile. Oyranus and the now user local settings went fine.

    I fixed this by installing from development section of the web software search page by installing from wolfie's repo. This caused some confusion as I had just installed a new monitor and had done a 2nd profile. Color Management in settings didn't seem to retain the change it and the apply button was greyed out. Logging out of kde and back in picked up the correct one though.

    My image editors were clearly using the correct profile but I had problems with some image viewers. Gwenview wasn't using it so have switched to Ristretto. I still need to get that to retain it's settings.

    I wouldn't recommend that, unless you install everything from my repo.

    Better use the "official" version from multimedia:color_management.

    But this thread is about 42.3, not 42.2, which comes with the latest version anyway.

    I did try the official version and posted because anyone running 42.3 wouldn't read the post I made about problems on 42.2. Just to warn about checking that image viewers are working correctly. I noticed because I happened to be working on fairly gaudy shot of a church window and noticed a significant drop in saturation which might also be down to an increase in brightness or some combination of the two. An odd problem to have.

    I keep getting the exact same segfault as the OP. It has been happening for quite some time.

    Shouldn't that be reported as a bug?
