Binary package hint: displayconfig-gtk
Hardy alpha 6 installed on a Core 2 Duo system with an Nvidia GeForce
7600GS graphics card. Primary monitor is a Mitsubishi Diamond Pro 920
(CRT). I've tried two secondary monitors, both LCDs - a Videoseven 17
inch (1280x1024) and an unbadged 15 inch (1024x768). In both cases
attempts to set up the secondary monitor via displayconfig-gtk have
failed.
displayconfig-gtk is at version 0.3.7
Steps to reproduce:
At start the primary monitor is working correctly, The secondary monitor
indicates it's input is out of range and nothing is displayed.
Run displayconfig-gtk
- Screen 1 is listed correctly. Screen 2 is disabled.
Click on screen 2.
Set monitor to LCD 1024x768
- note that "detect" button in monitor selection dialogue is greyed out.
Set resolution to 1024x768 at 60 Hz
Click "Secondary screen" radio button
- Extend default screen to the right is already selected so leave it
Click on Test
- Primary screen blanks momentarily.
- Secondary screen blacks out (backlight goes off then on) and then returns
to indicating input is out of range.
- Then get message as follows:
Configuration test failed
Please verify the selected devices and configuration
If displayconfig-gtk is run from a console via sudo the following text is
printed:
--- START QUOTE---
~$ sudo displayconfig-gtk
on_button_test_config_clicked()
xauth: creating new authority file /tmp/dcg-R8odej6090/xauthority

False
Sorry, this configuration video card driver
and monitor doesn't appear to work:
Messages from the X server:
Fatal server error:
--- END QUOTE ---
Note - there is just a blank line after the line "Fatal server error:"
At no point is anything displayed on the secondary screen except its own
message that the input signal is out of range. No combination of
resolution and refresh frequencies tried alters this.
