>Description:
After starting through KDM, the KDE desktop loads, but then it goes black screen.

Whether in VMware or VirtualBox, the following situation occurs: After installing KDE using the commands below, upon reboot, the kdm login window is visible. However, during the first login, only half of the KDE program windows are visible, while the rest remain in a black screen state. Subsequent logins result in a purely black screen

********************************************************************************
Note that your system uses syslog. All of kdm's internally generated messages
(i.e., not from libraries and external programs/scripts it uses) go to the
daemon.* syslog facility; check your syslog configuration to find out to which
file(s) it is logged. PAM logs messages related to authentication to authpriv.*.
