Crontab without Continuous Operation

Submitted by h2b on
System
OpenSUSE
Version
11.3
Symptom

Events triggered by crontab will not happen, if the PC is off-state at the time specified.

Unix systems including Linux have a mechanism that automatically can execute programs at a specified time – for instance daily at a certain time of day or weekly or monthly at a given day and here again at a certain time of day. All of this is triggered by a file named crontab which usually resides in the directory /etc (i. e., /etc/crontab) and contains the particular indications.

Problems when Configuring the Login Screen by the KDE4 Login Manager

Submitted by h2b on
System
KDE 4.3 / KDE 3.5 / KDM
openSUSE 11.2 (x86_64)
Symptom

Settings taken by the KDE4 login manager have no effect on the login screen.

After updating a KDE3-based Linux system (in my case openSUSE) to a new version based on KDE4, it may happen that the login screen cannot be changed by the login manager of KDE4 (System Settings|System|Login Manager) anymore. Even though the settings taken there are stored correctly at the dedicated location

/usr/share/kde4/config/kdm

Sound problems after updating KDE

Submitted by h2b on
System
KDE 4.3.1
openSUSE 11.2 (x86_64)
Symptom

KDE sound ringing out only sporadic, although working with non-KDE programs.

After updating from openSUSE 11.1 to version 11.2 and the incorporated transition from KDE 3.5 to 4.3 on one PC the sound generated by KDE applications (including system notifications) only worked every once in a while: when logging in it was there or it was not until the end of the session, where this behaviour appeared to be arbitrary and non-reproducible. At the same time, non-KDE programs did not show such bugs, their sound happened to perform faultless.
