Pointer missing on login

[themusicgod1]

When I login there is no pointer. I unplug my mouse & replug again...pointer appears. Has happened a half dozen times now, but not every time. Might just be when I shut down after using the touchpad (usually I have the touchpad disabled). This laptop has a touchpad and an IBM mouse.

Bus 001 Device 008: ID 04b3:3107 IBM Corp. ThinkPad 800dpi Optical Travel Mouse

root@Hedy:/home/themusicgod1# xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=13 [slave pointer (2)]
⎜ ↳ HID 04b3:3107 id=15 [slave pointer (2)]
 ...

Has been happening for at least a month, probably longer, but seems like it started some time after October.

themusicgod1, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[themusicgod1 (themusicgod1)]

Because it was an intermittent problem it's unclear that I could tag one way or another whether it's fixed. I have began with 4.1.0-040100rc1 -- I cannot reproduce so far, I will continue down the list, though to see if I can reproduce with one of the earlier kernels, too.

[penalvch (penalvch)]

themusicgod1, could you please test the latest mainline kernel (4.1-rc1) and advise to the results?

[themusicgod1 (themusicgod1)]

could not reproduce on 4.1-rc1

[themusicgod1 (themusicgod1)]

I'm not convinced that 4.1-rc1 doesn't exhibit issue, given that it's intermittent (happens ~18% of the time?). Was able to reproduce on 4.0.0-040000rc1 though.

v4.0-rc1-vivid could reproduce
v3.19.6-vivid could not reproduce
v3.19.5-vivid could not reproduce

[themusicgod1 (themusicgod1)]

Aha. Reproduced on 4.1-rc1

[penalvch (penalvch)]

themusicgod1, did this problem not occur in a release prior to Vivid?

[themusicgod1 (themusicgod1)]

I had different hardware, then: different video card, motherboard/cpu/bios -- I think I upgraded hardware around September....I might not have restarted enough to have noticed it until October.

[Brad Figg (brad-figg)]

This change was made by a bot.

[themusicgod1 (themusicgod1)]

Upgrade to wily kicked me over to xfce(?) ...this hasn't happened since I've started using xfce4/its greeter. :. it's probably closer related to lightdm than linux.

[themusicgod1 (themusicgod1)]

( xfce4's greeter is lightdm, on wily that would be lightdrm 1.15.0-0ubuntu1 )

[themusicgod1 (themusicgod1)]

Pretty sure this hasn't happened since I upgraded to wily.
