    Default system policies prevent you from getting the brightness level

    Hi I hope this is the correct place to post this question fairly new to Linux
    I keep getting this request from the system to enter the system password

    "system policies prevent you from getting the brightness level "

    I have read a number of posts about this problem for 11.2
    one said it might be a bug
    I did try to implement some of the repairs most of witch ended in "No such file"

    This system has just been update from 12.2 using the online update to 12.3, 64 bit amd
    I did see this system request a couple of times before the update and hoped the update would fix it,

    Any help would be wonderful

    That's impossible.

    An upgrade of 12.2 to 12.3 has to be done necessarily in one of these
    documented ways:

    Online upgrade
    method

    Offline upgrade
    method


    Chapter 16. Upgrading the System and System Changes



    An online update can not do a system upgrade. If you tried, your system
    is broken.

    Just a guess: Maybe your user session isn't registered with logind.
    Could you please post the output of the following command in a terminal window:
    Code:
    loginctl

    I believe I used that page to update from the 12.2 to 12.3 I know it was through the supper user konsole
    Might it be broken that is a possibility from what you say (respecting your superior knowledge in this matter)
    It appears to be working the only other issues known about is Thunderbird is slowing down to a crawl and the Brother dcp j925dw scanner is not being recognised the printing works,

    That looks ok.

    Then maybe your system policies are just not set to the defaults...
    What does the following say?
    Code:
    pkcheck --action-id org.kde.powerdevil.backlighthelper.brightness --verbose
    I assume you are using KDE here. If not, please tell so.

    PKCHECK(1) pkcheck PKCHECK(1)



    NAME
    pkcheck - Check whether a process is authorized

    SYNOPSIS
    pkcheck [--version] [--help]

    pkcheck [--list-temp]

    pkcheck [--revoke-temp]

    pkcheck --action-id action {--process { pid | pid,pid-start-time } | --system-bus-name busname}
    [--allow-user-interaction] [--enable-internal-agent] [--detail key value...]

    DESCRIPTION
    pkcheck is used to check whether a process, specified by either --process or --system-bus-name, is
    authorized for action. The --detail option can be used zero or more times to pass details about
    action. If --allow-user-interaction is passed, pkcheck blocks while waiting for authentication.

    The invocation pkcheck --list-temp will list all temporary authorizations for the current session
    and pkcheck --revoke-temp will revoke all temporary authorizations for the current session.

    This command is a simple wrapper around the polkit D-Bus interface; see the D-Bus interface
    documentation for details.

    RETURN VALUE
    If the specified process is authorized, pkcheck exits with a return value of 0. If the
    authorization result contains any details, these are printed on standard output as key/value pairs
    using environment style reporting, e.g. first the key followed by a an equal sign, then the value
    followed by a newline.

    KEY1=VALUE1
    KEY2=VALUE2
    KEY3=VALUE3
    ...

    Octects that are not in [a-zA-Z0-9_] are escaped using octal codes prefixed with \. For example,
    the UTF-8 string føl,你好 will be printed as f\303\270l\54\344\275\240\345\245\275.

    If the specificied process is not authorized, pkcheck exits with a return value of 1 and a
    diagnostic message is printed on standard error. Details are printed on standard output.

    If the specificied process is not authorized because no suitable authentication agent is available
    or if the --allow-user-interaction wasn't passed, pkcheck exits with a return value of 2 and a
    diagnostic message is printed on standard error. Details are printed on standard output.

    If the specificied process is not authorized because the authentication dialog / request was
    dismissed by the user, pkcheck exits with a return value of 3 and a diagnostic message is printed
    on standard error. Details are printed on standard output.

    If an error occured while checking for authorization, pkcheck exits with a return value of 127
    with a diagnostic message printed on standard error.

    If one or more of the options passed are malformed, pkcheck exits with a return value of 126. If
    stdin is a tty, then this manual page is also shown.

    NOTES
    Since process identifiers can be recycled, the caller should always use pid,pid-start-time to
    specify the process to check for authorization when using the --process option. The value of
    pid-start-time can be determined by consulting e.g. the proc(5) file system depending on the
    operating system. If only pid is passed to the --process option, then pkcheck will look up the
    start time itself but note that this may be racy.

    AUTHENTICATION AGENT
    pkcheck, like any other polkit application, will use the authentication agent registered for the
    process in question. However, if no authentication agent is available, then pkcheck can register
    its own textual authentication agent if the option --enable-internal-agent is passed.
    Manual page pkcheck(1) line 1 (press h for help or q to quit)


    I believe this is a kde set up excepted the default set up from the original disk
    I hope this is what yopu wanted
    Also sorted the Thunderbird issue out that was a root kit scanner playing badly,

    This is not the output needed but it seems the command is malformed so we will have to wait for wolfi323 to give you a different command to try.

    Right. I made a mistake, sorry!

    I wanted to have the output of:
    Code:
    pkaction --action-id org.kde.powerdevil.backlighthelper.brightness --verbose
