plymouthd does not quit on starting kdm

[molostoff]

Binary package hint: plymouth

Just after login into KDE sc4.5 I see plymouthd --mode=boot still running and eating 'wakeups' (in terms of powertop) about 20% cpu. Since I do not know a way to disable it I need manual kill -9 action to stop it.

According to /etc/init/plymouth-stop.conf plymouthd should quit on starting kdm, but it won't.

In fact, what /etc/init/plymouth-stop.conf shows that it's kdm's responsibility to kill plymouthd. If kdm hasn't done this, it's a bug in kdm. Reassigning to that package; the kubuntu folks should feel free to reassign this back to plymouth if they show that kdm is doing the right thing, but at the very least it'll be easier for the kdm maintainers to reproduce this issue than the plymouth maintainers, and there haven't been reports of this with gdm.

[Steve Langasek (vorlon)]

oh; but you mention KDE sc4.5, where Ubuntu 10.04 only shipped sc 4.4. It sounds like maybe you've installed a newer kdm that was packaged improperly for use on Ubuntu?

[molostoff (molostoff)]

Yep, should it redirected to kubuntu-ppa, according to http://www.kubuntu.org/news/kde-sc-45, or I have to repost bug again there?

I have temporarily fixed it:

pre-start script
    case "$JOB" in
    gdm|0kdm|ubiquity|oem-config)
        exit 0
        ;;
    *)
        exec /bin/plymouth quit
        ;;
    esac
end script

Added a kubuntu-ppa task, and since maverick has the same configuration you can leave the ubuntu task open.

Just another confirmation for this.

@molostoff, comment #4:

is the "fix" code meant to replace the content in "/etc/init/plymouth-stop.conf"?

Thanks in advance, Nikos

[molostoff (molostoff)]

Yes, it is /etc/init/plymouth-stop.conf, I suppose they will fix this file later anyway.

[molostoff (molostoff)]

indeed, not all the file, but kdm - 0kdm (disabling kde match in case construct)

[Steve Langasek (vorlon)]

This bug appears to also apply to the 4.5 packages present in maverick.

[Harald Sitter (apachelogger)]

Fix pushed to branch.

This bug was fixed in the package kdebase-workspace - 4:4.5.1-0ubuntu1

---------------
kdebase-workspace (4:4.5.1-0ubuntu1) maverick; urgency=low

  [ Felix Geyer ]
  * New upstream release.
  * Drop patches that are applied upstream:
    - kubuntu_115_loginscreen_kcm_no_rootonly.diff
    - kubuntu_117_no_malloc_check.diff
  * Update install and symbols files.

  [ Harald Sitter ]
  * Drop CVE-2010-0436_fix_kdm_local_exploit.diff for good, the remaining
    portion of this patch was applied at another position within the same
    file which essentially made the variable set twice.
  * Update kubuntu_34_kdm_plymouth_transition.diff to quit plymouth when
    startServerSuccess is called, which should be called whenever successful
    startup was archived. (LP: #618450)
