XPS 13 9350 Unity freeze

[Alexandre Strzelewicz]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0].

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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hello Joseph,

I received my XPS 2 days ago, there was already Windows 10 installed. I downloaded Ubuntu 16.04, created an ubuntu usb key (with unetbootin) and installed the system as is.

I have not made any kernel upgrade.

How to test the latest upstream kernel? If you have any link describing how to do this, its welcome.

[Alexandre Strzelewicz (strzelewicz-alexandre)]

Alright I found the link, I will try to upgrade and will keep you informed

[Alexandre Strzelewicz (strzelewicz-alexandre)]

Ok I just tried it:

shant@onyx:~$ uname -a
Linux onyx 4.6.0-040600rc2-generic #201604031130 SMP Sun Apr 3 15:32:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

And the bug still exists (happened 2 times during 5/10 secs)

If I can be of any help to diagnose this bug, please let me know,

[Alexandre Strzelewicz (strzelewicz-alexandre)]

4.6 rc3 installed, been one hour playing around, no freeze at all!

[Alexandre Strzelewicz (strzelewicz-alexandre)]

Sometimes the lag is there, but it's much more usable than before

[Alexandre Strzelewicz (strzelewicz-alexandre)]

It stopped working (total freeze), if I can be of any help please let me know

Alexandre Strzelewicz, as per http://www.dell.com/support/home/us/en/19/product-support/product/xps-13-9350-laptop/drivers?os=biosa an update to your computer's buggy, insecure, and outdated BIOS is available (1.3.3). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.
