<FONT COLOR="#000000">> Hi all,</FONT>
<FONT COLOR="#000000">> I have several systems connected to a Level1 KVM switch. According</FONT>

<FONT COLOR="#000000">> Now I have connected several Linux systems to this switch with different</FONT>

<FONT COLOR="#000000">> I get a resolution of 1920x1200 with all the systems. As soon as I connect</FONT>

<FONT COLOR="#000000">> Looking into the log files I can see, that the switch is reporting to</FONT>

<FONT COLOR="#000000">Add a monitor section to your config with the appropriate sync ranges</FONT>

The monitor section was already there. So I added the following lines (Values taken from monitor spec):<BR>
<BR>
HorizSync 30-94<BR>
VertRefresh 48-85<BR>
<BR>
<BLOCKQUOTE TYPE=CITE>

<FONT COLOR="#000000">and modes for your monitor </FONT>

How do I insert the correct modes here? Using Modeline? Every Modeline I use lets X crash immediately after starting it.<BR>

<FONT COLOR="#000000">then specify the modes you want in the</FONT>
<FONT COLOR="#000000">display sub-section of the screen section of your config. That should</FONT>
<FONT COLOR="#000000">do the trick.</FONT>

My screen section looks like the following including the modes.<BR>
Section "Screen"<BR>
Identifier "aticonfig-Screen[0]"<BR>
Device "aticonfig-Device[0]"<BR>
Monitor "aticonfig-Monitor[0]"<BR>
DefaultDepth 24<BR>
SubSection "Display"<BR>
Viewport 0 0<BR>
Depth 24<BR>
Modes "1920x1200" "1600x1200" "1280x1024"<BR>
EndSubSection<BR>
EndSection<BR>
