2016-03-19 Thread Christopher M. Penalver
stinger, it will help immensely if you filed a new report with Ubuntu by 
ensuring you have the package xdiagnose installed, and that you click the Yes 
button for attaching additional debugging information running the following 
from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see

2016-01-30 Thread mjh
I saw there were .debs there and, against my better judgement, installed the 
latest (4.5.0-040500rc1)
It fails to boot, giving me a black screen after "loading ramdisk.."

[Touch-packages] [Bug 1525390] Re: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A

2016-01-29 Thread Christopher M. Penalver
mjh, in order to allow additional upstream developers to examine the issue, at 
your earliest convenience, could you please test the latest upstream kernel 
available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please 
keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the 
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was 
released upstream.
4) Install instructions are available at 
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

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, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

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 your understanding.

** Tags removed: bios-outdated-4.0.1
** Tags added: latestbios-4.0.3

** Changed in: xorg (Ubuntu)
   Importance: Low => Medium

[Touch-packages] [Bug 1525390] Re: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A

2016-01-13 Thread Shivam Kakkar
I am also facing the same problem on Lenovo Z50 70, although not as frequent as 
OP.
I have attached my log (grep 'Atomic' in the log).
The command `sudo dmidecode -s bios-version && sudo dmidecode -s 
bios-release-date` gives this output.
9BCN91WW
07/21/2015
which is latest, and can be checked from here:
http://support.lenovo.com/in/hi/products/laptops-and-netbooks/lenovo-z-series-laptops/lenovo-z50-70/downloads/ds100528.
I don't know if it is related but google-chrome crashed while playing video in 
full screen when I pressed [Esc] to return to normal display. I had to kill 
compiz and google-chrome to get it back.(Using tty1)

Shivam Kakkar, it will help immensely if you filed a new report with the Ubuntu 
repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.

Hi,

Since making the bug report, I've updated the BIOS, without any apparent
improvement.

[Touch-packages] [Bug 1525390] Re: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A

2016-01-08 Thread Christopher M. Penalver
mjh, thank you for reporting this and helping make Ubuntu better.

As per http://www.dell.com/support/home/us/en/19/product-
support/product/inspiron-15-3552-laptop/drivers an update to your
computer's buggy and outdated BIOS is available (4.0.1). 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. As well, 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 New. If it's not reproducible, please mark 
this as Invalid.

Thank you for your understanding.
