gnome-display-properties: "Mirror screens" problems

thank you for your bug report, what ubuntu version, videocard and videodriver do you use?

Ubuntu Jaunty, video card intel Mobile 945GM with 'intel' driver.

This is on a Dell Latitude D620.

what monitors are used? do you have a dock station and try to use the laptop and an external screen? what resolution do you use for each of those?

Built-in monitor, and an external one on a docking station. I use the native resolutions on both: 1152x864 for the external one and 1280x960 for the internal one.

not confirming on jaunty using a dell d630, do you have any error on the command line when applying the settings?

After recent updates, I am no longer able to duplicate the problem. I'll assume it's fixed for now, and re-open if I encounter it again.

I'm getting the same error on Jaunty, using the rolled-back (Intrepid) version of the Intel driver (unfortunately, I'm one of those people whose graphics systems do NOT play nicely with Jaunty's updated Intel drivers). Anybody have any thoughts as to potential workarounds?

Graphics info:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Driver: Intel 2.4

Many thanks.

I have also experienced this problem. Trying to attach the external monitor after boot and setting the external monitor to mirror (800x600 on both internal and external) causes "Could not apply the selected configuration" "Method invoked for ApplyConfiguration returned FALSE but did not set error" on the gnome configure monitor applet. My system is an MSI wind (Intel 945) running Jaunty.

Hello all,

I can confirm this problem on a Lenovo T61 Thinkpad using Ubuntu 9.04 with Nvidia graphics card. I used to work with the proprietary driver (which worked rather fine) and wanted to try out how it works without, and as it occurs, it doesn't work.

I have Simon's problem. Lenovo T61 Thinkpad, Ubuntu 9.04 with Nvidia Quadro NVS 140M. I tried the nv driver because the proprietary driver doesn't support XRandR, but in this configuration, any attempt to make the laptop display to the built-in laptop screen results in this error.

With Ubuntu 9.04, on LG LS70 express laptop - with intel chipset, all updated - i have same problem.
BUT inputing "xrandr --auto" in terminal works fine and sets the 2 displays right.

Forgot to state in last post I'm connected to an external Samsung T240 Syncmaster.
By the way - at the login screen i do see the screens mirrored but as soon as I login - one of the screens goes to standby.

Hi,

I can confirm this on a Dell E6400 using Jaunty 9.04 (32 bit). This laptop has the Intel:

Mobile 4 Series Chipset Integrated Graphics Controller

Whenever I try with any external monitor to mirror screens, if I turn on that monitor before mirroring screens, I get the message

Method invoked for ApplyConfiguration returned FALSE but did not set error

Of course if I don't turn on the external monitor I don't get mirrored displays, but it doesn't complain.

If I restart X with the external display connected, it does work, but that is painful.

Thanks,

Rob
