Hi,

we&nbsp;do&nbsp;have&nbsp;a&nbsp;Dell&nbsp;Latitude&nbsp;D620&nbsp;notebook&nbsp;which&nbsp;is&nbsp;equipped&nbsp;with&nbsp;the&nbsp;

NVIDIA&nbsp;Quadro&nbsp;NVS&nbsp;110M&nbsp;video&nbsp;chipset.&nbsp;Onto&nbsp;this&nbsp;notebook&nbsp;we've&nbsp;installed&nbsp;

RHEL&nbsp;5.&nbsp;Video&nbsp;output&nbsp;is&nbsp;working&nbsp;fine&nbsp;if&nbsp;the&nbsp;notebook&nbsp;is&nbsp;not&nbsp;docked;&nbsp;on&nbsp;

the&nbsp;internal&nbsp;display&nbsp;and&nbsp;the&nbsp;connected&nbsp;NEC&nbsp;TFT&nbsp;(using&nbsp;the&nbsp;analog&nbsp;

output).&nbsp;However&nbsp;if&nbsp;the&nbsp;notebook&nbsp;is&nbsp;being&nbsp;docked&nbsp;to&nbsp;the&nbsp;port&nbsp;replicator&nbsp;

we&nbsp;only&nbsp;get&nbsp;a&nbsp;corrupted&nbsp;X&nbsp;screen&nbsp;on&nbsp;the&nbsp;NEC&nbsp;LCD&nbsp;(using&nbsp;the&nbsp;digital&nbsp;port&nbsp;

of&nbsp;the&nbsp;port&nbsp;replicator).&nbsp;If&nbsp;we&nbsp;switch&nbsp;back&nbsp;to&nbsp;the&nbsp;text&nbsp;console&nbsp;the&nbsp;

console&nbsp;is&nbsp;initially&nbsp;corrupted,&nbsp;too.&nbsp;After&nbsp;blindly&nbsp;entering&nbsp;the&nbsp;login&nbsp;

credentials&nbsp;on&nbsp;the&nbsp;text&nbsp;console&nbsp;we&nbsp;get&nbsp;a&nbsp;proper&nbsp;prompt&nbsp;in&nbsp;text&nbsp;mode.

We've&nbsp;compared&nbsp;the&nbsp;Xorg&nbsp;log&nbsp;files&nbsp;when&nbsp;docked&nbsp;and&nbsp;not&nbsp;docked&nbsp;and&nbsp;found&nbsp;

only&nbsp;the&nbsp;obvious&nbsp;differences&nbsp;(analog&nbsp;output&nbsp;instead&nbsp;of&nbsp;digital).

We&nbsp;also&nbsp;tried&nbsp;the&nbsp;NVIDIA&nbsp;proprietary&nbsp;drivers&nbsp;but&nbsp;these&nbsp;just&nbsp;create&nbsp;a&nbsp;&quot;No&nbsp;

signal&quot;&nbsp;on&nbsp;the&nbsp;LCD.&nbsp;We've&nbsp;already&nbsp;replaced&nbsp;the&nbsp;port&nbsp;replicator&nbsp;with&nbsp;a&nbsp;

known&nbsp;good&nbsp;one.&nbsp;Didn't&nbsp;help&nbsp;either.

Windows&nbsp;XP&nbsp;is&nbsp;also&nbsp;not&nbsp;showing&nbsp;this&nbsp;issue;&nbsp;i.e.&nbsp;everything&nbsp;works&nbsp;as&nbsp;

expected&nbsp;when&nbsp;the&nbsp;notebook&nbsp;is&nbsp;docked&nbsp;and&nbsp;the&nbsp;display&nbsp;is&nbsp;connected&nbsp;to&nbsp;the&nbsp;

port&nbsp;replicator.

Anyone&nbsp;got&nbsp;any&nbsp;suggestions&nbsp;on&nbsp;what&nbsp;to&nbsp;try&nbsp;else?

Thanks&nbsp;&&nbsp;Kind&nbsp;Regards,

Dirk
