This way your personal data can be easily protected against -unwanted access from others in case you loose your machine. - - -STATUS: - -Still in development, but should be useable. - - -REQUIREMENTS: - -- QDM needs Linux-PAM (Pluggable Authentication Modules for Linux) for - proper user validation. - -- the /dev/fb0 device has to writeable to everyone ;-( - - -INSTALLATION: - -Per default this little add-on is not enabled. You have to do so -yourself for now, by setting a compile option variable called -QT_QWS_LOGIN .

Just open -the .ui file and edit the look of the dialog as you like. You can, for -instance, change the logo pixmap. QDM should also be ready for i18n so -far. - -Other configuration stuff, eg welcome string in the upper right, and -user list can be changed in the qdm_config.h file. - - -USAGE: - -The QDM comes up, when the QPE is started, and if the QPE is started -as 'root'. Being started as any other user, the uid couldn't be -changed and the login dialog wouldn't be ofg much use. - - -CONTACT: - -http://www.lisa.de diff --git a/core/opie-login/qdm_config.h b/core/opie-login/qdm_config.h deleted file mode 100644 index bf5b5a4..0000000 --- a/core/opie-login/qdm_config.h +++ b/dev/null @@ -1,30 +0,0 @@ -//-- -*- c++ -*- -
