Hello,

I confirm this bug on my Dell XPS12 Duo, with same Xorg output as above. I don't know if this is related, but the two-finger gestures are not available on the touchscreen display either.

I'd be most grateful if this could be fixed.

Many thanks and all the best

Carlo

Unfortunately, the Sputnik project relates only to the Dell XPS 13. For support on other models, you may have more luck opening a bug against vanilla Ubuntu.

Status changed to 'Confirmed' because the bug affects multiple users.

Reassign "Affects" to "linux-image-generic" base on Kyle's recommendation (https://bugs.launchpad.net/dell-sputnik/+bug/1103594/comments/3)

Status changed to 'Confirmed' because the bug affects multiple users.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hello,

After installing request kernel:

# dpkg --get-selections | fgrep 3.8.0
linux-headers-3.8.0-030800rc5 install
linux-headers-3.8.0-030800rc5-generic install
linux-image-3.8.0-030800rc5-generic install
linux-image-extra-3.8.0-030800rc5-generic install

It is impossible to boot, supposedly because of i915/Intel HD4000 issues. "Normal" boot leads to black screen (backlight turns off); "Recovery mode" leads to garbled output.
I tried disabling KMS, RC6, FBC: no change

Should I file a separate bug addressing the this i915/Intel HD4000 with the XPS 12?

Hello again,

I eventually have the i915/Intel HD4000 work along the 3.8 kernel: one must pass "i915.invert_brightness=1" kernel parameter

As for the Cypress Trackpad, it got even worse: it is now recognised a "ImPS/2 Generic Wheel Mouse", which is a regression compared to Quantal 3.5 Kernel:

# xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Atmel Atmel maXTouch Digitizer id=9 [slave pointer (2)]
⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
[...]

ERRATA: 'i915.invert_brightness=1' is *not* the way to go. Brightness is actually handled correclty... but when booting the XPS 12 with 3.8rc5, brightness is by default set to its minimum value (iow. off). One just needs to increase it with Fn+F5 to have the panel "wake up".

Note that this issue is also solved in the Quantal kernel, which, if I read correctly, incorporates all the quirks - for the brightness, trackpad, etc. - that have been developed as part of the Dell/Ubuntu Sputnik project (for the XPS 13). It appears none of this quirks are mainstream as per 3.8rc5 :-(

Thanks for reporting this issue. I will investigate.

FYI, the Cypress PS/2 Trackpad driver is queued up for inclusion in mainline Linux 3.9, but my expectation is that that version will exhibit the same problem as you're seeing in the Ubuntu kernels. (So further testing of mainline kernels isn't necessary at this time).

@Cédric - Yes, please do file a separate bug for the i915 brightness problem.

How do we test this fix?

This bug was fixed in the package linux - 3.8.0-7.15

The fix to enable the Cypress PS/2 trackpad in the Dell XPS12 (and possibly other laptops) now appears in the standard Ubuntu Raring kernel (as of 3.8.0-7.15) and is pending inclusion upstream in the mainline Linux 3.9 kernel.

The fix will also be applied to the standard Ubuntu Precise (12.04) and Quantal (12.10) kernels in the near future. In the meantime, the fix for those Ubuntu versions will be available via the Sputnik Project kernel PPA. Sputnik kernel version "kamal14" (available within a few hours) enables the Cypress trackpad on the XPS12:

My XPS 12 now works beautifully under Xubuntu 12.10 (quantal)
Thank you very very much!

This resolved my touch pad issues, but it broke a work-around that I had been using to get some multi-touch on the screen. I don't want to hijack this thread, but can anyone point me towards some information on getting the touch screen on the XPS 12 working correctly (two-finger scroll, re-sizing, etc)?

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi XPS12 users- We'd like to have this fix verified for the standard Ubuntu Precise (12.04) and Quantal (12.10) kernels, as noted by Steve above. Unfortunately, I don't have access to an XPS12, so I need your assistance...

If you're running the Sputnik kernel (for Precise or Quantal), then the latest version can be used to verify the bug fix. Check that the command 'uname -a' output a line which includes "kamal16".

If instead, you're running the standard Ubuntu Precise or Quantal kernel (not the Sputnik kernel), then you can verify the fix by installing the -proposed kernel (See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed).

For either case, verify that the command 'xinput' includes a "CyPS/2" line, and that the touchpad works as expected, then report back your results and the kernel version you tested here.

Thanks in advance for your help!

I have the Sputnik PPA and last time I checked I had the Kamal kernel. Because of this however, I just discovered I need to pay more attention to my updates. Anyway, I'm showing the CyPS/2 trackpad with the gemeric kernel, so I'm not sure if this confirms or denies anything.

@GaryParr,

That is not the -proposed kernel which is the one we'd like tested. If you could install that and confirm life is good, that would be most helpful.

I can confirm, using the quantal kernel with -proposed. I don't know if there are any new fancy features I should be looking out for with the touchpad, but two-finger vertical scrolling, and three-finger moving of windows both work and I have noticed that there is a Pointing Devices control panel now, with a CyPS/2 set of options for things like palm detection.

I hope that helps.

@GaryParr and @amcmorl, thanks for your help. Amcmorl's verification from the kamal16 kernel (which is based on 3.5.0-28.47 -proposed) is sufficient for Ubuntu Quantal.

(So we're still looking for an XPS12 user running Ubuntu Precise 12.04.)

We've been unable to find anyone running Precise on this particular hardware. However, this patch has been upstream for a while and the testing on Quantal has been good. Also, this is a pretty small patch which has been reviewed by several people so I think we can accept it for Precise.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
