External monitor on Dell Inspiron 8000 with older ATI video card running Ubuntu 10.04


Hi,

I've been trying to figure this out for a while so I thought I'd try and see if anyone else here has some luck solving this.

I am trying to get Ubuntu 10.04 to set my external monitor as the default for the logon prompt, etc or to have it <completely> mirror my LCD screen from boot.

I have a Dell Inspiron 8000 laptop with an ATI Mobility M4 video card which Ubuntu sees as a r128 when choosing the driver. The external monitor is an older CRT capable of 1280x1024 resolution as is the LCD screen.

The reason why I want to have the external CRT monitor mirror the LCD or become the default is because the LCD screen has stopped working and needs repair.

I have tried using xrandr but haven't had any luck so far.

I have been able to configure the xorg.conf file so that the external monitor shows up as "LeftOf" the LCD screen and all resolution settings are working without issue.

When Ubuntu boots the logon prompt shows up on my Laptop LCD screen. After logging on, the top and bottom panels appear on my CRT and it appears to be "to the left" of the LCD screen.

When I choose System->Preferences->Monitors the option for "Same Image in all Monitors" is grayed out.

Here is my xorg.conf file:

If the LCD screen isn't working, remove it from the Server Layout.
Code:
Section "ServerLayout"
Identifier "Default Layout"
Screen "Screen1"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
You don't need to remove the "Screen0" section, just don't use it.

Hi jschiwal,

Thank-you for the suggestion. I gave it a try. However, it didn't work.

After making the appropriate changes to the xorg.conf file and rebooting an error box was displayed with the following:

------------------------------------------------------------------
Ubuntu is running in low graphics mode.

The following error was encountered. You may need to update your
configuration to solve this.

(EE) Screen0 deleted because of no matching config section.
(EE) Device(s) detected but none match those in the config file.
------------------------------------------------------------------

Any other suggestions?

My memory goes back that far. The ati produced a r7000 which I bought in 2001. It was much better than the r128, and totally crap. agp is 4x(standard)

1280x1024@75hz may be faster than the dotclock will allow. For the modeline you have, the sums are
1688x1066x75 = 135mhz(rounded)
The r128 may not have an infinitely variable dot clock, just set spots. If you're into gaming, I'd suggest minesweeper, or chess :-).

I'd look for vesa modes, and try some of those. All that stuff is listed with the framebuffer package, IIRC.
