    KDE frozen after update Fedora 28

    Hi everyone,

    After installing, reported as successful, the updates on 6/25/18, my KDE desktop loads and then freezes. I can boot into a terminal w/o issue. Weirdly, dnf history does not show the 6/25 update; it records it as on 6/19. The system date and KDE clock settings are correct and KAlarm and KOrganizers pop up and freeze. I've not been able to rollback or undo the update (some 135 files) since a version of NetworkManager is not available. Is there a way to skip the unavailable package and do an undo? Or do I need to remove and reinstall KDE, which may or may not solve the problem? I've looked at the logs in /var/log but don't see anything obvious. But I'm not sure what I'm looking for, either.

    And to further complicate things, my backup machine, also running F 28, is also freezing after the most recent updates; the Gnome desktop on that machine seems fine. So it appears to be a KDE issue. Any suggestions/tips? I haven't found anything online or in any forums that discusses this.

    Thanks much.

    Try to do another update in terminal. It is possible that this could fix your problem.

    If that doesn't work, you could install another desktop-environment. Follow this Fedora wiki: https://docs.fedoraproject.org/quick...ironments.html

    Re: KDE frozen after update Fedora 28

    Donatom,

    Thanks for your response. When I tried another update this morning, dnf listed the eight kf5- files that are (apparently) causing the problem but says that dnf cannot install the best update due to conflicts and/or not available. Very confusing. I looked at doing an update with the --allow-erasing option but that would appear to strip away many of the KDE app's I use most. Very confusing. And, yes, I decided earlier to add another desktop environment as a workaround. Hopefully, the folks who know about this stuff will come up with a fix so I can go back to KDE.

    And maybe someone will have a suggestion other than the alternate desktop so I'm going to leave this thread open for a while longer.

    Thanks again.

    Show the results of "# journalctl -b" which will show all logs since the most recent boot.

    Re: KDE frozen after update Fedora 28

    Okay. I'll apologize in advance: the journalctl -b output almost 1800 lines of code and I don't see how/where I can attach a file here. So before I provide that vast amount of data, here's a "script" transcript of what happens when I try to update. I see the identified problems; I don't know how to fix them. :-( (I also do not know another way to capture the screen output other than with script.)

    Thanks much for looking at this!

    Re: KDE frozen after update Fedora 28

    The problem would seem to stem from the fact that you have the epel repo installed and enabled. Packages from there are in conflict with the packages from the Fedora repos. Disable the epel repo and try the check-update again.

    Re: KDE frozen after update Fedora 28

    Hi Pablo,

    Thanks for the suggestion. I disabled the epel repo and ran check-update again and then update; no errors were reported. I rebooted but, unfortunately, the desktop remains frozen after it loads. the reminders from KAlarm pop up but I can't do anything with them (or anything else on the desktop). The mouse works; don't know about the keyboard, tho it works fine when I move to a different desktop (CA+F2). I'm now wondering if I should just start disabling repo's to see if that solves the problem, at least temporarily?

    Thanks again.

    Sid

    Re: KDE frozen after update Fedora 28

    Well, with the most recent updates, everything seemed to work fine. Until I rebooted at which point the desktop froze on loading. All the updates are from the Fedora and Updates repos. Anyone have another suggestion? I'm not opposed to reinstalling KDE - I just don't know if that'll solve the problem.
    Thanks.

    Re: KDE frozen after update Fedora 28

    To be clear, my advice to disable the epel repo was to correct the problem you were having with doing dnf updates you posted, and not as a cure-all to fix the freezing problem as well. For that, I really don't have any advice to offer.

    Re: KDE frozen after update Fedora 28

    I understand and do appreciate your suggestion. When I did the update this morning, the conflict messages no longer appeared so your advice was spot-on and I thank you again for it. I just need to either keep searching for an answer or bite the bullet and do a reinstall.

    Re: KDE frozen after update Fedora 28

    Hi,
    I'm having the same issue when booting to default kernel after recent updates. It's a weird thing, if I select the last 4.16 available kernel from the boot menu everything goes OK. It seems to be a kernel related issue. Any additional help will be appreciated.

    Re: KDE frozen after update Fedora 28

    UPDATE! I used LXQT instead KDE and I had no freezing issues but... I was not able to connect to my WIFI network. Back again to KDE I realized my computer hangs while trying to connect to my WIFI network. I'm using an USB WIFI adapter with Realtek R8188EU chipset (r8188eu module), if you're using a similar adapter it could be a good idea to move this thread to the Hardware forum.

    Re: KDE frozen after update Fedora 28

    After a bit more experimentation I found the freezing issue is more likely related to the USB WIFI adapter.
    - My computer boots without issues if the adapter is unplugged
    - If I plug the WIFI adapter after a successful boot the computer freezes after a couple seconds
    - I don't have this issue with other computer which uses a different WIFI integrated adapter (Intel), both computers have Fedora 28 KDE up to date installed with almost exactly the same packages installed.

    What would be better? To start a new thread in the Hardware Forum or to move this? I'd prefer not to do double posting.

    Re: KDE frozen after update Fedora 28

    Luispa,

    Thanks for the suggestion! I had assumed the problem was exclusively a KDE issue and didn't consider using an earlier kernel. I had to go back two kernel releases to "correct" (unfreeze) the desktop. My MB does not have any WiFi capability; however, since WiFi packages install automatically with the updates, I'm now wondering if one or more of the WiFi packages is the root cause of the issue for me. Since this computer will always be hard-wired to a network, maybe removing all the WiFi packages is a permanent solution. If you know, is that possible and, if so, how is it done? Is there a way to remove all the WiFi modules from the kernel?

    As for starting a new thread, I think the topic might best stay here since we're using different hardware setups. But that's only a guess on my part.

    Thanks much, once again.

    Sid

    It seems something goes wrong when the r8188eu module tries to load the firmware file. If this is the issue the problem could be present when using hardware which requires to load external firmware files.
