Often, something will not be quite right when you initially fire up the
|
|
X server. This is almost always caused by a problem in your <tt>XF86Config</tt>
|
|
file. Usually, the monitor timing values are off, or the video card
|
|
dot clocks set incorrectly. If your display seems to roll, or the edges
|
|
are fuzzy, this is a clear indication that the monitor timing values or
|
|
dot clocks are wrong. Also be sure that you are correctly specifying
|
|
your video card chipset, as well as other options for the <tt>Device</tt>
|
|
section of <tt>XF86Config</tt>. Be absolutely certain that you are using
|
|
the right X server and that <tt>/usr/X11R6/bin/X</tt> is a symbolic link
|
|
to this server.
|
|
<P>
|
|
If all else fails, try to start X ``bare''; that is, use a command such as:
|
|
<P><TT> <code>X > /tmp/x.out 2>&1 </code>
|
|
<P></TT>
|
|
You can then kill the X server (using the <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img292.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img293.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img294.gif">
|
|
key combination) and examine the contents of <tt>/tmp/x.out</tt>. The X server
|
|
will report any warnings or errors---for example, if your video card doesn't
|
|
have a dot clock corresponding to a mode supported by your monitor.
|
|
<P>
|
|
The file <tt>VideoModes.doc</tt> included in the XFree86 distribution contains
|
|
many hints for tweaking the values in your <tt>XF86Config</tt> file.
|
|
<P>
|
|
Remember that you can use <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img295.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img296.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img297.gif"> and
|
|
<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img298.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img299.gif">-<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img300.gif"> to switch between the video modes
|
|
listed on the <tt>Modes</tt> line of the <tt>Screen</tt> section of
|
|
<tt>XF86Config</tt>. If the highest resolution mode doesn't look right,
|
|
try switching to lower resolutions. This will let you know, at least,
|
|
that those parts of your X configuration are working correctly.
|
|
<P>
|
|
Also, check the vertical and horizontal size/hold knobs on your monitor.
|
|
In many cases it is necessary to adjust these when starting up X. For
|
|
example, if the display seems to be shifted slightly to one side, you can
|
|
usually correct this using the monitor controls.
|
|
<P>
|
|
The USENET newsgroup <tt>comp.windows.x.i386unix</tt> is devoted to
|
|
discussions about XFree86. It might be a good idea to watch that newsgroup
|
|
for postings relating to your video configuration---you might run across
|
|
someone with the same problems as your own.
