[gentoo-user] kdm 4.2.2 not configurable?

[gentoo-user] kdm 4.2.2 not configurable?

[Roy Wright]

Howdy,

Well I just went back to using two monitors in twinview mode after a few
months of single monitor suffering.  But now when KDM start I get half a
screen of garbage on the left half of the left monitor and on the right
half of the right monitor.  OK, should just need to set the background
image.  So head over to Computer, System Settings, Advanced, Login
Manager but got a problem, everything there is disabled.  Docs imply
there should be an Admin button but it's not there (Have: Help,
Defaults, Reset(disabled), & Apply(disabled)).

Thinking, oh well, off to /usr/kde/4.2/share/config/kdm, edit kdmrc and
set GreeterScreen to -1 (the only multi display setting I saw) to see
what happens.  Ran genkdmconf.  Restarted xdm.  No change.

Any ideas?

TIA,
Roy

KDM does the same for me on a wide-screen monitor. In fact it could be
a security risk because after logging out of KDE, random pieces of
screen from the last session sometimes show up on the garbage parts on
the sides, including potentially sensitive information. It does not
appear to support any kind of screen size detection. What you need to
do is find (or make) a theme that is the same size/aspect ratio as
your display setup and then it'll be okay. It's trying to use a 4:3
theme on a 8:3 or 16:9 or whatever and apparently the KDM people
haven't gotten around to dealing with that yet.

For now, I simply edited kdmrc and set UseTheme to false.

Still haven't figured out how to use System Settings, Advanced, Login
Manager.  Can't get anything to be enabled for editing.  I've tried:

* chmod -R 755 the config directories (/usr/share/config &
/usr/kde/4.2/share/config)

* reset the config files with: genkdmconf --no-old

The ownership of the conf files is root:root, so am thinking the
permissions should be 775, but I've found multiple sources that state
the perms should be 755, which would make since if I had an Admin button
like they refer to.  Maybe a sudo setup or something...

Thank you,
Roy

KDE4 system settings has no support for allowing you to enter
Administrator mode from system settings, but some distros have their
own patch to enable this. I think it is planned to be added in KDE 4.4
officially.

For now you can open a "run" dialog and type "kdesu systemsettings" to
have the admin options enabled for editing.

That works great!
