lorenzo.chianura, the next step is to fully reverse commit bisect from kernel 4.2 to 4.3-rc7 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

lorenzo.chianura, thank you for reporting this and helping make Ubuntu better. To advise, at this point, this is not considered a duplicate of another report, or vice versa. Despite this, as per http://support.lenovo.com/us/en/products/laptops- and-netbooks/lenovo-z-series-laptops/lenovo-z50-70 an update to your computer's buggy and outdated BIOS is available (91). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 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. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** This bug is no longer a duplicate of bug 1492764 [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) ** Tags added: bios-outdated-91 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509794 Title: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) Status in linux package in Ubuntu: Incomplete Bug description: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) in a kubuntu 15.10 x64 fresh installation, on a Lenovo z50-70 (intel HD4400/ nVidia 840M) Not sure if it is related, but I'm experiencing lots of graphical glitches.

[Kernel-packages] [Bug 1509794] Re: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0)
I've just successfully updated the BIOS, but the problem is still here. The output of sudo dmidecode -s bios-version give me: 9BCN91WW and then sudo dmidecode -s bios-release-date give me: 07/21/2015 If it could be useful, I can attach a new dmesg log file, although I found that excluded the line that describes the BIOS version, nothing has changed. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509794 Title: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) Status in linux package in Ubuntu: Confirmed Bug description: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) in a kubuntu 15.10 x64 fresh installation, on a Lenovo z50-70 (intel HD4400/ nVidia 840M) Not sure if it is related, but I'm experiencing lots of graphical glitches.

[Kernel-packages] [Bug 1509794] Re: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0)
lorenzo.chianura, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel 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 issue 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 X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for the fast response. As you have suggested I searched for a safe method to update my BIOS without using Windows, following https://help.ubuntu.com/community/BIOSUpdate, but it seems that there is not a "BIOS update CD" image for my laptop model. So I will install Windows on my machine to safely perform the BIOS update and then reinstall Kubuntu 15.10 so I can see if the fix worked. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509794 Title: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) Status in linux package in Ubuntu: Incomplete Bug description: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) in a kubuntu 15.10 x64 fresh installation, on a Lenovo z50-70 (intel HD4400/ nVidia 840M) Not sure if it is related, but I'm experiencing lots of graphical glitches.
