[gm45] intel xrandr dual head auto config only configures part of one screen on Dell Lattitude E4300

[evanjfraser]

Binary package hint: xorg

I have a Dell Lattitude E4300 (Intel GM45 chipset).

When logging in with it plugged into the Dell docking station with two Dell DVI 1600x1200 monitors connected, Only the Left hand monitor powers up, and although it displays the full resolution, the mouse is only moveable within a small section (about 1024x768? from the top left hand corner).

When I then bring up the Display control panel, it shows me that both monitors are enabled (and laptop screen disabled). But for me to be able to use the full LH screen and for the RH screen to power on I have to disable the RH screen, hit apply, and then re-enable the RH screen and hit apply.

Thanks, Evan.

Does moving a window across the border enable the mouse to enter the area?
Are you using compiz?

Hello,
The behaviour has changed slightly since the bug was reported, due to package updates I suspect.

The current behaviour is now that the Left screen remains in standby, and the Right hand screen powers up and shows the right hand side of the extended desktop. However, the desktop wallpaper is shrunken and tiled.

As such I can't actually open a window to try to move it, but I believe that this didn't work before the behaviour changed.

No I am not using compiz.

I'll attach some screenshots shortly.

Thanks, Evan.

This is what the extended desktop is meant to look like.

[evanjfraser (evanjfraser)]

This is what the desktop looks like on bootup.

Left hand monitor is off, and there's something weird going on with the RHS. I can't move the mouse over into the screen that's on.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

It seems likely to me this bug is gone; the -intel driver has improved immensely in Karmic and a lot of bugs are being reported as no longer present. So hopefully that's the case here too.
