IBM Thinkpad X41 & docking station >> no joy :-(

[thinkpad]

(docking station: x4 dock type 2506)
With Win XP Pro SP3, X41 dock & undock without any problems.

In Ubuntu, however, when pressing the blue undock button on the docking station:

 - The screen goes blank (with backlight remaining on),
 - with some SSD/HDD activity;
 - ctrl alt del causes a shut down after ... seconds, indicating that the system itself hasn't "crashed" but is still (somewhat ?) responsive.

Thank you.

btw, the symptoms are the same even with the DVD drive physically removed from the docking station...

thus, I think DVD / CD drive (un-)mount issues can safely be ruled out...

New data:

I had another go at warm (standby) docking / undocking (with and without the DVD drive).

First I was excited to have found a workaround solution: go into standby and then just press the mechanical eject (2) button (instead of the blue electronic button (1) ) - but that solution soon turned out to be only slightly more promising:

The system wouldn't appear to crash immediately - however, it would _NOT_ go back into standby again (either it would end up showing the login-screen, or it would crash (half-moon blinking for eternity)), - when attempting standby in the undocked state.

:-(

Feel like throwing the docking station out of the window... but then: the hardware's not the problem: it works on windoze.

:-(

Anybody out there?

Hi thinkpad,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 691272

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi Jeremy Foshee,

Thanks for your (automated) reply.

I would like to help - but I have only a small SSD on my X41 and hence wouldn't like to install daily or nightly dev builds or mainline kernels - or even debian, for testing purposes - on my main up-to-date maverick installation.

Would running the apport-collect -p linux 691272 command in my current maverick installation be of any additional help to you? Or has this already been done in the process of filing this bug?

"expires in 36 days" ?

I hope not - not as long as it isn't solved.

For me this is important, albeit not urgent. But I would not like to see it being forgotten about !

THANKS,

:-)

USB issue ?

Any ideas for a good work-around ?

I have the same issues with a X41.

If I use an older kernelversion (2.6.31),
there aren't any dock and undock problems,
but with the latest kernel in Maverick this problem still exist.

Maybe there will be a workaround or solution for this bug?

Best regards
