Comment 1 Greg McGee 2013-02-10 10:19:00 CET

Duplicate, 

Possibly related: I recall selecting "kscreen" (v0.0something) vs. the alternative when I ran updates on a fresh install.

Comment 2 Greg McGee 2013-02-10 10:21:17 CET

note Fresh install was due to HDD upgrade, not bad MGA behaviour.

Comment 3 Nicolas Lécureuil 2013-02-10 14:17:28 CET

Please install kscreen-debuginfo

Comment 4 Greg McGee 2013-02-10 22:20:35 CET

No package named kscreen-debuginfo.

Kscreen MGA current version is shown as 0.0.71...

I'm about to reinstall as I can't figure out what the alternative dependency is, and with kded dead, quite a few things no longer work.

Comment 5 Greg McGee 2013-02-10 22:24:53 CET

Found fix: Missing kscreen configuration library, missing dep:libkscreen

Comment 6 Greg McGee 2013-02-10 22:26:30 CET

No longer crashes kded with libkscreen installed.
(sorry about the multiple posts, working 2 keyboards and coffee deficiency)

Comment 7 Greg McGee 2013-02-10 22:36:04 CET

The update loaded, still works, is the dependancy for libkscreen fixed?

(some comments don't seem to be showing up)

Comment 8 Rick Bailey 2013-02-10 22:41:19 CET

Tried installing kscreen-debuginfo
"[root@fatboy ~]# urpmi kscreen-debuginfo
No package named kscreen-debuginfo
[root@fatboy ~]# urpmi kscreen
Package kscreen-0.0.71-3.mga3.x86_64 is already installed"

However after the latest updates the bug no longer exists, as Greg McGee reports the missing libkscreen has fixed it.

Comment 9 Luc Menut 2013-02-10 22:49:54 CET

(In reply to comment #7)
> The update loaded, still works, is the dependancy for libkscreen fixed?
> 

Yes, it's fixed with kscreen-0.0.71-3.
I added the dependency on libkscreen through '%arch_tagged KSC_XRandR.so' to ensure the install of libkscreen from the same arch as kscreen.

regards,
Luc

Comment 10 Greg McGee 2013-02-10 22:55:09 CET

Cool, this one can probably be closed then.

<1 day bug>fix is not bad at all ;-)

Luc Menut 2013-02-10 23:36:48 CET

Status: NEW => RESOLVED
Hardware: x86_64 => All
Resolution: (none) => FIXED
