Common troubleshooting for remote graphical interface xmanager login failure in Aix

Environment products: rs6000, platform Aix, model all, software version V4 or later
The problematic user logs on to Aix through remote graphics software (such as xmanager), and the user cannot log on. How can this problem be solved?
Answer
1. Run
/Usr/dt/bin/dtconfig-kill (disable the CDE process)
/Usr/dt/bin/dtconfig-D (do not enter the CDE interface next time you start the machine)
/Usr/lib/X11/xdm/xdmconf-E (enable the xdm function)
Startsrc-s xdm (start xdm)
PS-Ef | grep xdm (check that the xdm process is running)
PS-Ef | grep dtlogin (the CDE process should be stopped)

2. Edit xserversFile,
VI/usr/lib/X11/xdm/xservers

Remove the # Of the last line

#: 0 local/usr/bin/X11/X-Force
