<title>Argyll Installation on Linux</title>
</head>
<body>
<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>
Some systems (Fedora ?) seem to be missing normal X11 libraries like
<b>libXss.so</b>, so you may have to install <b>libXScrnSaver</b>,
i.e. "sudo dnf install libXScrnSaver".<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> Load "extmod" <br>
<br>
in the appropriate (or any) section of
your Xorg.conf file, to allow the XF86Video LUT
extensions 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>

<big style="color: rgb(51, 102, 255);"><span style="font-weight:
bold;"><a name="InstAccess"></a>Setting up instrument access:<br>
<br>
</span></big>By default most Linux based systems make devices
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
oldest, the following sub-systems may need to be configured to
permit this:<br>

marked as COLOR_MEASUREMENT_DEVICE by the

probably need to disable libmtp (look in the udev configuration).<br>

chip that the <b>JETI</b> specbos <b>1511, 1501</b> use. You may
have to add yourself to the<span style="font-weight: bold;">

<h5><span style="color: rgb(204, 51, 204);"><a name="None"></a>No

A few systems have in place a security configuration such that
anyone logging in at the console of a machine has access to all the
local devices.<span style="color: rgb(204, 51, 204);"><span

<font color="#330033"> /usr/lib/udev/rules.d/69-cd-sensors.rules</font>
file.<br>
</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>
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 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>,
<b>/sbin/udevcontrol reload_rules</b> or <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&q=man+udev&btnG=Search&meta=&aq=f&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>
sudo usermod -a -G colord $USER<br>
<br>
or<br>
su root<br>
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>
If usermod doesn't recognize the -a flag try "usermod -A
colord $USER".<br>
If this doesn't work you will have to run "id yourusername" to
list the current supplemental<br>
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>
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
instruments
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
style="font-weight: bold;">/etc/hotplug</span> directory exists on
your system.<br>
<br>
Assuming we want to configure for all Argyll supported USB
instruments, copy the file <span style="font-weight: bold;">usb/</span><span
style="font-weight: bold;">Argyll.usermap</span> from the binary
or source distribution into <span style="font-weight: bold;">/etc/hotplug/usb/Argyll.usermap</span>
with owner root, group root, permissions 644.<span
style="font-weight: bold;"></span><br>
<br>
<br>
(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
style="font-weight: bold;">Argyll</span> from the binary or source
distribution into <span style="font-weight: bold;">/etc/hotplug/usb/Argyll</span>
with owner root, group root, permissions 744.<span
style="font-weight: bold;"></span><br>
<br>
<span style="font-weight: bold;">YOU THEN NEED TO:</span><br>
<br>
You will then <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>
sudo usermod -a -G colord $USER<br>
<br>
or<br>
su root<br>
usermod -a -G colord $USER<br>
<br>
<br>
(If the usermod program isn't found as root, it might be in
/usr/sbin, ie. use /usr/sbin/usermod .... etc.<br>
If usermod doesn't recognize the -a flag try "usermod -A
colord $USER".<br>
If this doesn't work you will have to run "id yourusername" to
list the current suplemental<br>
groups, and add colord using just "usermod -G
group1,group2,... yourusername"<br>
Another option may be to use gpasswd -a $USER colord))<br>
<br>
You may find that the <span style="font-weight: bold;">colord</span>
group doesn't exist on your system, and if so you will need to
create it:<br>
<br>
sudo groupadd -r colord<br>
<br>
and then add yourself to the colord group.<br>
<br>
You may have to log out and then in again for the groups to become
effective.<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>
<span style="font-weight: bold;"></span> <br>
<h5><span style="color: rgb(204, 51, 204);"><a name="serial"></a>Serial
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>, <span
style="font-weight: bold;">uucp </span>or <b>dialout </b>group,
so the best way of getting access to the serial ports is to add
yourself to the correct group. (You can identify the correct group
by looking at the group name shown by <b>ls -l /dev/ttyS*</b> )<b><br>
<br>
</b> You can add yourself to a group either by using a "Users
and Groups" system administration tool, or on the command line using
"usermod":<br>
<br>
su root<br>
usermod -a -G dialout $USER<br>
<br>
or<br>
<br>
sudo usermod -a -G dialout $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>
If usermod doesn't recognize the -a flag try "usermod -A
dialout $USER".<br>
If this doesn't work you will have to run "id yourusername" to
list the current suplemental<br>
groups, and add a tty, uucp or dialout group using just
"usermod -G group1,group2,... yourusername"<br>
Another option may be to use gpasswd -a $USER dialout)<br>
<br>
You may have to log out and then in again, or even re-boot your
system for the group to become effective.<span style="font-weight:
