    <h1> <u>Installing the software on Linux with X11<br>
      </u></h1>
    <br>
    You will need to unpack the downloaded file in the location you have
    chosen to hold the executable files. Typically this might be in <span
      style="font-style: italic;">/usr/local/</span>, or perhaps <span
      style="font-style: italic;">$HOME/bin/</span>. You would then
    unpack the files using <span style="font-weight: bold;">tar -zxf</span>
    <span style="font-weight: bold;">archivename.tgz</span>, which will
    create a directory <span style="font-weight: bold;">Argyll_VX.X.X</span>,
    where X.X.X is the version number, and the executables will be in <span
      style="font-weight: bold;">Argyll_VX.X.X/bin</span> You will also
    have to configure your $PATH environment variable to give access to
    the executables from your command line environment. The .tgz file
    also contains several useful reference files (such as scanner chart
    recognition templates, sample illumination spectrum etc.) in the ref
    sub-directory, as well as all the current HTML documentation in a
    doc sub-directory. You may want to copy things to more standard
    locations such as /usr/local/bin, /usr/local/argyll/bin etc.,
    depending on the conventions used on your system.<br>
    <br>
    <big style="color: rgb(51, 102, 255);"><span style="font-weight:
        bold;"><a name="bell"></a>Note on the system bell:</span></big><br>
    <br>
    When reading strips using the Eye-One Pro or ColorMunki instrument,
    the system bell is used to indicate when the instrument the ready to
    be used, and to provide feedback on any problems. On some Linux
    installations the system bell may be disabled. As well as checking
    the terminal and GUI sound preferences, you may have to enable the
    used of the PC speaker driver, which can be done by adding the
    command <span style="font-weight: bold;">/sbin/modprobe pcspkr </span>to










    the <span style="font-weight: bold;">/etc/rc.local</span> startup
    script. You may also have to run <span style="font-weight: bold;">xset










      b 100 1000 100</span> in your local setup, if you are running in
    an X11 environment. You can check that the system bell is operating
    by doing an "echo ^G", where ^G is ctrl-G.<br>
    <br>
    <big style="color: rgb(51, 102, 255);"><span style="font-weight:
        bold;"><a name="multimonitor"></a>Note on X11 multi-monitor
        setups:</span></big><br>
    <br>
    When working with a multi-monitor X11 configuration, note that you
    will only be able to individually calibrate monitors if the
    multi-window extension you are using (if any), supports access to
    the individual screen Video LUT tables that are used for
    calibration. The native X11 multi-screen addressing supports this,
    as does the Xinerama extension, and XRandR V1.2.<br>
    <br>
    The proprietary NVidia TwinView and ATI MergeFB extensions do not
    currently support access to the individual screen Video LUTs, so
    calibration of each screen independently is impossible if either of
    these extensions are running. You can switch to using Xinerama to
    solve this problem, or you can try doing a calibration for the
    screens that do have accessible Video LUTs with these proprietary
    extensions, or ignore calibration and rely purely on display
    profiling. Use the dispwin tool to figure out what works on your
    system. The NVidia ATI binary drivers do not seem to properly
    support XRandR V1.2 either, even though they claim to do so. You may
    have to set the <span style="font-weight: bold;"></span><span
      style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
    environment variable if the XRandR V1.2 extension is faulty.<br>
    <br>
    If these limitations trouble you, then as a valuable customer of
    NVidia or AMD/ATI, perhaps you should contact them and urge them to
    fix the problems with Video LUT access in their proprietary
    multi-monitor extensions and XRandR implementation, bringing their
    support for multi-monitors on X11 up to the same standards as other
    operating systems. Ask them to add full and correct support for the
    XRandR V1.2 extension.<br>
    <br>
    <big style="color: rgb(51, 102, 255);"><span style="font-weight:
        bold;"><a name="VideoLUTs"></a>Fixing access to Video LUTs:</span></big><br>
    <br>
    Some users have noted that their default X11 installation doesn't
    properly enable access to the video card Video Lookup Tables
    (RAMDAC). The Video LUTs are used for display calibration purposes,
    and a warning will be issues by the <span style="font-weight:
      bold;">dispcal</span> and <span style="font-weight: bold;">dispread</span>
    tools if there is a problem with this. Without access to the
    VideoLUTs, you won't be able to use display calibration.<br>
    <br>
    The problem may be because certain X11 extensions aren't being
    loaded by default. You may want to check that you have<br>
    <br>
    <big style="color: rgb(51, 102, 255);"><span style="font-weight:
        bold;"></span></big>&nbsp; Load&nbsp; "extmod" <br>
    <br>
    in&nbsp;the&nbsp;appropriate&nbsp;(or&nbsp;any)&nbsp;section&nbsp;of
    your Xorg.conf file, to allow the XF86Video&nbsp;LUT
    extensions&nbsp;to function correctly.<br>
    <br>
    Another source of problems is if the display isn't configured with a
    suitable visual. Typically for high quality color you need to be
    using at least <span style="font-weight: bold;">24 bits</span> per
    pixel (8 Bits for each of Red, Green and Blue channels), but more
    importantly the number of entries in the the VideoLUTs needs to
    match the depth of the screen. So if the VideoLUTs have 256 entries
    per channel, then the screen must be using 8 bits per channel to
    match. Or 64 entries and 6 bits. Or 4096 entries and 12 bits, etc.
    Running "dispwin -D" may give some clues as to what the nature of
    the problem is. You might have to look into your xorg.conf or XRANDR
    setup, or on some distributions there will be some configuration
    program that will let you choose the display configuration (ie. YaST
    or SaX2 on openSUSE, etc.).<br>

    inaccessible to user mode programs, so it is necessary to make some
    modification to your permissions so that Argyll tools are able to
    access the Color Measurement Instruments. In order from newest to

      </span></h5>
    <span style="color: rgb(204, 51, 204);"> </span>Recent Fedora based
    systems include Gnome Color Manager, which comes with a udev rule
    for color instruments. You can check this by looking for the <span
      style="font-weight: bold;">/etc/udev/rules.d</span> or in <b>/usr/lib/udev/rules.d/69-cd-sensors.rules</b>
    file. If this exists and is up to date enough to include the
    instrument you want to use, then all you have to do is add yourself
    to the <b>colord</b> group, ie:<br>
    <br>
    &nbsp;&nbsp; sudo usermod -a -G colord $USER<br>
    <br>
    If the <b>69-cd-sensors.rules</b> file is out of date and does not
    include the latest instruments supported by Argyll, then the
    simplest thing to do is to replace the <b>69-cd-sensors.rules</b>
    file with the <span style="font-weight: bold;">usb/</span><span
      style="font-weight: bold;">55-Argyll.rules</span>. You will need
    to do this as root, and set the owner as root, group root,
    permissions 644. You may need to re-plug in your instrument to get
    changes to the udev rules recognised.<br>
    <h5><span style="color: rgb(204, 51, 204);"><a name="udev2"></a>USB
        instruments access using udev, with no existing <font
          color="#330033">/etc/udev/rules.d</font> or <font
          color="#330033">/usr/lib/udev/rules.d/69-cd-sensors.rules</font>
        file.<br>
      </span></h5>
    Most recent systems use udev to manage device names and permissions,
    but by default color instruments may not be accessible to normal
    system users.<br>
    To solve this a udev rule file needs to be added that modifies the
    group and permission of any Color Measurement Instruments, and you
    may then need to add yourself to that group.<br>
    <br>
    First check whether other rules are in <span style="font-weight:
      bold;">/etc/udev/rules.d</span> or in <b>/usr/lib/udev/rules.d</b>,
    and use the appropriate directory.<br>
    (You may also want to check in that directory whether
    55-Argyll.rules or some other .rules file that is setup to enable
    color instruments already exists in that directory.)<br>
    <br>
    <span style="font-weight: bold;"></span>Copy the file <span
      style="font-weight: bold;">usb/</span><span style="font-weight:
      bold;">55-Argyll.rules</span> from the binary or source
    distribution into <span style="font-weight: bold;">/etc/udev/rules.d/55-Argyll.rules</span>
    or <span style="font-weight: bold;">/usr/lib/udev/rules.d/55-Argyll.rules



    </span>(as appropriate) with&nbsp;owner root, group root,
    permissions 644.<br>
    <br>
    If you are on an <span style="font-weight: bold;">older system</span>
    that uses a udev that doesn't recognize the syntax used in
    55-Argyll.rules, or that doesn't have rules to create the libusb
    /dev/bus/usb/00X/00Y device entries, you should install the <span
      style="font-weight: bold;">usb/45-Argyll.rules</span> file instead
    - See below.<br>
    <br>
    On recent systems the new rules file will be notices as soon as you
    plug the instrument in again.<br>
    On older systems you may need to run <b>/sbin/udevtrigger</b>,&nbsp;











    <b>/sbin/udevcontrol reload_rules</b> or&nbsp; <span
      style="font-weight: bold;">/sbin/udevstart</span> or reboot to get
    the new file noticed.<br>
    <br>
    (You may want to refer to <a
      href="http://reactivated.net/writing_udev_rules.html">this
      document</a> for more guidance on modifying udev rules, as well as
    <a
href="http://www.google.com/search?hl=en&amp;q=man+udev&amp;btnG=Search&amp;meta=&amp;aq=f&amp;oq=">this</a>.)<br>
    <br style="font-weight: bold;">
    <span style="font-weight: bold;">YOU THEN MAY NEED TO:</span><br>
    <br>
    If your system is <span style="font-weight: bold;">not</span> using
    the ACL to manage device access for console users (the file <span
      style="font-weight: bold;">/var/run/ConsoleKit/database</span>
    doesn't exist on your system), then you will <span
      style="text-decoration: underline;">need to add</span> yourself to
    the <span style="font-weight: bold;">colord</span> group, if you
    are not already a member of it. You can do this either by using a
    "Users and Groups" system administration tool, or on the command
    line running as root:<br>
    <br>
    &nbsp;&nbsp; sudo usermod -a -G colord $USER<br>
    <br>
    or<br>
    &nbsp;&nbsp;&nbsp; su root<br>
    &nbsp;&nbsp;&nbsp; usermod -a -G colord $USER<br>
    <br>
    (If the usermod program isn't found as root, it might be in
    /usr/sbin, ie. use /usr/sbin/usermod .... etc.<br>
    &nbsp;If usermod doesn't recognize the -a flag try "usermod -A
    colord $USER".<br>
    &nbsp;If this doesn't work you will have to run "id yourusername" to
    list the current supplemental<br>
    &nbsp;groups, and add them plus colord using just "usermod -G
    group1,group2,... yourusername")<br>
    <br>
    You may find that the <b>colord</b><b></b> group doesn't exist on
    your system, and if so you will need to create it:<br>
    <br>
    &nbsp; sudo groupadd -r colord<br>
    <br>
    and then add yourself to the <b>colord</b> group.<br>
    <br>
    You may have to log out and then in again for the groups to become
    effective.<br>
    <br>
    You can check whether the instrument is being recognized and set to
    the colord group by comparing the output of <span
      style="font-weight: bold;">ls -l -R /dev/bus/usb</span> without
    and then with the instrument plugged in.<br>
    <br>
    You can test whether your instrument is accessible by plugging it in
    and then running "spotread -?" and looking for it listed after the <span
      style="font-weight: bold;">-c</span> option.<br>
    <h5><span style="color: rgb(204, 51, 204);"><a name="hotplug"></a>USB

        access using hotplug:<br>
      </span></h5>
    Under <span style="font-weight: bold;">much older versions of Linux</span>,
    you should look into the hotplug system configuration for USB
    devices. You know you are running this because the <span

    your system.<br>
    <br>
    Assuming we want to configure for all Argyll supported USB

      style="font-weight: bold;">Argyll.usermap</span> from the binary
    or source distribution into&nbsp; <span style="font-weight: bold;">/etc/hotplug/usb/Argyll.usermap</span>

      style="font-weight: bold;"></span><br>
    <br>
    <br>
    &nbsp;(For even older versions, append the lines above to <span
      style="font-weight: bold;">/etc/hotplug/usb.usermap</span>, and
    you may have to run <span style="font-weight: bold;">update-usb.usermap</span>)<br>
    <br>
    Then copy the file <span style="font-weight: bold;">usb/</span><span

instruments











        access:</span><br>
    </h5>
    If you have a serial instrument then you may find that by default
    you don't have permission to access the serial ports or a Serial to
    USB adapter. Most systems make the serial ports available to any
    user in the <span style="font-weight: bold;">tty</span> and <span
      style="font-weight: bold;">uucp </span>group, so the best way of
    getting access to the serial ports is to add yourself to those
    groups. You can do this either by using a "Users and Groups" system
    administration tool, or on the command line using "usermod":<br>
    <br>
    &nbsp;&nbsp;&nbsp; su root<br>
    &nbsp;&nbsp;&nbsp; usermod -a -G tty,uucp $USER<br>
    <br>
    or<br>
    <br>
    &nbsp;&nbsp; sudo usermod -a -G tty,uucp $USER<br>
    <br>
    (If the usermod program isn't found as root, it might be in
    /usr/sbin, ie. use /usr/sbin/usermod .... etc.<br>
    &nbsp;If usermod doesn't recognize the -a flag try "usermod -A
    colord $USER".<br>
    &nbsp;If this doesn't work you will have to run "id yourusername" to
    list the current suplemental<br>
    &nbsp;groups, and add a tty or uucp group using just "usermod -G
    group1,group2,... yourusername")<br>
    <br>
    You may have to log out and then in again for the group to become
    effecive.<span style="font-weight: bold;"><br>
