<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">If you
are unsure if your computer is setup correctly, it is suggested that
you run all of these tests and verify that each of them passes. If,
for some reason, one or more of these tests fail, please refer to and
follow the instructions below.</FONT></P>
<H2 CLASS="western">Make sure that your video card has working 3D
acceleration 
</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Some
on-board and lower end video cards may fail the 3D acceleration test
even when they are working correctly. Cedega's video card test
threshold is set too high for certain cards. To manually test your
video card please follow the steps below. </FONT>

<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">To test
your graphics card for OpenGL support execute the following command:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>$
glxinfo | grep &quot;direct rendering&quot;</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">output
will return &quot;direct rendering:&quot;</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">If this
is 'Yes' or 'Enabled' then OpenGL is likely set up correctly. If it
is listed as 'No' or 'Disabled' then double check your 3D setup.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">You may
also want to try a performance test. Type the following to run a
simple benchmark included on most popular Linux distributions:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>$
glxgears</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">The
glxgears program will output an FPS (Frames Per Second) rating to the
command line. If 3D acceleration is correctly enabled for your video
card then the reported FPS should be well over 500 FPS, at the
default window size. If the output shows less than 500 FPS then you
should double check your 3D setup.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">If you
are on a 64-bit machine, and your machine succeeds in the previous
two tests but failed the 3D acceleration test in Cedega, then you may
also wish to check that you have 32-bit OpenGL libraries installed. 
See below for more details.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">In some
cases it is possible to have multiple OpenGL libraries installed on
your system. If you are having problems with Cedega, you may wish to
check whether this is the case for your system. You can do so by
executing:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>$
locate libGL</I>.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">This
will display a list of all of the OpenGL libraries you have on your
system. In particular, you should be wary of having libGL in both
/usr/lib and /usr/X11R6/lib. Sometimes the software-only Mesa OpenGL
libraries are installed in /usr/X11R6/lib, and hardware accelerated
drivers are installed elsewhere. We do not recommend removing the
Mesa libraries from /usr/X11R6/lib unless you are seeing slow
rendering in games running under Cedega.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">If you
are running a 64-bit distribution of Linux, and only see entries in a
directory like /usr/lib64 and not /usr/lib, then this is a good
indicator that you are probably missing 32-bit versions of the OpenGL
libraries.  If you are using a NVIDIA video card, then installing the
32-bit libraries means reinstalling your drivers and selecting &ldquo;Yes&rdquo;
when prompted as to whether or not you wish to install 32-bit
libraries.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">If you
are using a NVIDIA video card, please make sure that the latest
drivers from http://www.NVIDIA.com have been installed on your
system, and that OpenGL is working properly. Some distributions
custom build versions of these drivers for use with only their
distribution. These builds can sometimes cause conflicts, and users
may wish to use the drivers available directly from NVIDIA.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Users
with ATI Radeon 8500 or above video cards should use the proprietary
ATI drivers available from </FONT><FONT COLOR="#000080"><U><A HREF="http://www.ati.com/"><FONT FACE="Arial, sans-serif">www.ati.com</FONT></A></U></FONT><FONT FACE="Arial, sans-serif">.
Some distributions build versions of these drivers for use with that
specific distribution. These builds can sometimes cause conflicts and
users may wish to use the drivers available directly from ATI.</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Other
video cards may only be able to use open source drivers such as
MESA/DRI to enable 3D acceleration. A number of conflicts between
Cedega and these drivers remain, so users should expect increased
setup times and non-working games when using these cards. TransGaming
does not recommend using Cedega with these video cards. </FONT>

<H2 CLASS="western">Check your CD/DVD devices and mount points for
permissions</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Many
Windows games use copy protection systems that require Cedega to have
'read' access to your CD/DVD device, as well as 'read' and 'execute'
access to your CD/DVD mount point. Check your CD/DVD devices and
mount points to ensure that Cedega has appropriate permissions. Some
forms of copy protection require the ability to see hidden files on
the disc. To make these files available to Cedega, you will also need
to add the &ldquo;unhide&rdquo; option to the CD/DVD fstab list. (In
particular, SuSE 9.3 users should note that the unhide option is
incompatible with the subfs auto mounting solution provided with this
distribution. SuSE 10 and later do not share this drawback, although
SuSE 10.1 has other issues with hybrid discs.  TransGaming recommends
upgrading such systems to SuSE 10.2 instead.) You will need root
permissions to make changes to your /etc/fstab. </FONT>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">To
ensure that the correct permissions are available:</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Check
the /etc/fstab file for the line that represents your CD/DVD drive.
That line should indicate the device such as /dev/hdc or /dev/scd0. </FONT>
</P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">For
example:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>/dev/cdroms/cdrom0
/mnt/cdrom iso9660 user,unhide,noauto,ro 0 0</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">In the
above example the device is /dev/cdroms/cdrom0</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Perform
ls -la /dev/DEVICE on the CD/DVD device. Check to see if all users
have rx permissions. The example below does not have the correct
permissions:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>brw-------
1 wulfram disk 22, 0 Aug 26 06:20 /dev/hdc</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Your
permissions should look like:</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>brwxr-xr-x
1 wulfram disk 22, 0 Aug 26 06:20 /dev/hdc</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">(you may
also have W permissions, but they are not necessary for Cedega to
run).</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">To
change the permissions on your device and mount points, execute the
following commands as 'root':</FONT></P>
<P STYLE="margin-bottom: 0cm"><I><FONT FACE="Arial, sans-serif">$
chmod a+xr <B>[device]</B></FONT></I></P>
<P STYLE="margin-bottom: 0cm"><I><FONT FACE="Arial, sans-serif">$
chmod a+rx <B>[mount point]</B></FONT></I></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">In some
cases the device may be a symbolic link to another device (indicated
by -&gt; /cdroms/cdrom0 for example) If this is a symbolic link, you
will also need to check the permissions on the linked device.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">For
example: </FONT>

<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif"><I>lr-xr-xr-x
1 root root 13 Aug 21 14:45 /dev/cdrom -&gt; cdroms/cdrom0</I></FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">In this
case, you would check the permissions of /dev/cdroms/cdrom0 as well.</FONT></P>
<H2 CLASS="western">Check your XF86Config-4 or Xorg.conf file 
</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Games
often attempt to change your screen resolution to fit their needs.
Make sure that the 'Screen' section of your X config file has a
number of resolutions. The most common resolutions are: 1600x1200,
1280x1024, 1024x768, 800x600, 640x480. If the game is not running at
full screen, check the game settings to see what resolution it is
attempting to use, and make sure you have that resolution listed in
the configuration file.</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Note:
You may experience improved performance with some games on older
cards when running the X server at 16-bit color depth, however most
modern games require 24-bit color depth for correctness. Games which
require pixel shaders, in particular, will typically require 24-bit
color depth.</FONT></P>
<H2 CLASS="western">Disable Sound Servers</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Many
Linux desktop systems such as KDE and Gnome run sound servers such as
'ARTS', 'esd', or 'JACK'. These sound servers can cause sound
problems within Cedega by reserving exclusive access to the sound
device. If you are having sound problems, make sure to disable any
sound servers or other applications that may be using sound, such as
'xmms'.</FONT></P>
<H2 CLASS="western">Check free disk space limitations</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">Some
systems may be set up with restrictive disk space quotas on the /home
directory. These limitations can cause Cedega to incorrectly report
available free space. You may experience problems installing games if
the available space is reported incorrectly, or if there is not
enough space available on your system. If you experience any error
messages reporting that there is not enough hard drive space to
install a game, then disable quotas, or symbolically link to a device
with more free disk space available.</FONT></P>
<H2 CLASS="western">Pthreads</H2>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">By
default, Cedega should be able to detect automatically whether your
Linux distribution requires you to use pthreads or not. If no
installer or game seems to be working for you, it is possible this
detection scheme isn't working on your distribution.</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">You can
try forcing pthreads to be on or off, thereby not relying on the
autodetection scheme. Edit ~/.cedegarc, and add (or modify) a
pthreads_forced line under the [transgaming] header, like this:</FONT></P>
<P STYLE="margin-bottom: 0cm"><BR>
</P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">To force
pthreads usage on:</FONT></P>

<P><FONT FACE="Arial, sans-serif">Some distributions' versions of
mount now run with the &ldquo;noexec&rdquo; option unless otherwise
specified. Running games from a partition mounted with noexec can
cause an error = 21 message.</FONT></P>
<P><FONT FACE="Arial, sans-serif">To fix this issue, edit /etc/fstab
and modify the partition line by changing 'noexec' to 'exec' in the
mount options.</FONT></P>
<P STYLE="margin-bottom: 0cm"><FONT FACE="Arial, sans-serif">For
example, change:</FONT></P>
