[Anmar Oueja]

As much as I love to have this fixed in the final release, I understand
Daniel's hesitation.   The point is to try and keep things as stable as
possible prior to releasing. Good news it is fixed and it is just a
matter of time before it is released.

[Kernel-packages] [Bug 1763156] Re: Bluetooth doesn't reconnect to my headsetup post resume from sleep

[Anmar Oueja]

The following patches were added to the 5.48 version in Fedora and they
did fix the problem. Perhaps worth you adding them as well. Please see
https://koji.fedoraproject.org/koji/buildinfo?buildID=1040106 and the
bug https://bugzilla.redhat.com/show_bug.cgi?id=1534857

Title:
  Bluetooth doesn't reconnect to my headsetup post resume from sleep

Status in bluez package in Ubuntu:
  New

Bug description:
  Steps to repro:

  * Cold boot the laptop
  * Pair it with bluetooth headset
  * Listen to music
  * Turn off the headset or turn off the bluetooth on the laptop
  * Play music, sound comes out of the laptop speakers
  * Turn on the headset back on or the bluetooth on the laptop
  * Headset reconnects with the laptop and audio plays from the headset

  -- all the above is expected --

  * Suspend the laptop
  * wait a minute or two for the headset to power down
  * Resume the laptop
  * Turn on the bluetooth headeset
  * It doesn't automatically reconnect to the laptop (not expected behaviour)
  * Launch Gnome Settings and select Bluetooth and force the headset to connect
  * It connects for 2 seconds then disconnects (not expected behaviour)

  The only to get the headset to reconnect again is by restarting the
  bluetooth.service using systemctl.

Re: [Kernel-packages] [Bug 1718936] Re: Can't boot Artful 17.10 live images on XPS 15 (9560)

[Anmar Oueja]

link textThe soln to this is to turn the nouveau driver modesettings and
leave things up to the Intel board.

To do that, you need to edit the /etc/default/grub and add
nouveau.modeset=0 to the GRUB_CMDLINE_LINUX

so it looks like this: GRUB_CMDLINE_LINUX="nouveau.modeset=0"

Once done, just run update-grub to update and reboot.

Good luck!

  Can't boot Artful 17.10 live images on XPS 15 (9560)

Bug description:
  I usually test Ubuntu beta releases. With Artful, I haven't been able

  The boot proceeds properly if I pass the "nomodeset" kernel boot

[Anmar Oueja]

The fix is easy enough. here is what you need to do.

== Booting a live image
* Enter the boot prompts by presseing Esc
* Edit the boot prompt and append nouveau.modeset=0 to the linux boot command 
line 

== Once installed, you need to do the following:
* Log into the system, assuming it work, if not, do the steps outlined above.
* edit /etc/default/grub file and locate the GRUB_CMDLINE_LINUX= line
* add nouveau.modeset=0 to it
* it should look like this: GRUB_CMDLINE_LINUX="nouveau.modeset=0"
* Save the file
* run sudo update-grub 
* Reboot and enjoy

Re: [Kernel-packages] [Bug 1697556] Re: Computer freezes after login - 4.10.0-22-generic

[Anmar Oueja]

Hopefully future kernel releases don't need the nouveau.modeset=0
option. But until then, 17.10 is rock solid (been full time on it for
the past 3+ weeks) without issues. Kudos to the Ubuntu and Canonical
teams for doing such a great job.

[Anmar Oueja]

I agree with Kai-Heng. 17.04 is getting old and given all the good
work that went into the 17.10 release, I recommend you switch to it
Hagen.

BTW, in 17.10, there is a problem on the XPS 15
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1718936) booting
from live CD and general use. You need nouveau.modeset=0 to the kernel
boot options.

[Kernel-packages] [Bug 1718936] Re: Can't boot Artful 17.10 live images on XPS 15 (9560)

[Anmar Oueja]

I have done some more testing and here are my findings:

* 4.12.14 works like a charm with nothing extra added to the command boot option
* 4.13.16 doens't boot and operate normally without nouveau.modeset=0 . The 
same go for 4.14-rc4

With nouveau.modeset=0, I can use the kernels that ship with 17.10 while
booting from USB stick, installing and normal use even if an external
monitor was plugged into the XPS 15.

Obviously something regressed but I can't tell what it is.

Title:
  Can't boot Artful 17.10 live images on XPS 15 (9560)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I usually test Ubuntu beta releases. With Artful, I haven't been able
  to boot the image on my XPS 15 (9560) Dell laptop because the boot
  process stops half way.

  The boot proceeds properly if I pass the "nomodeset" kernel boot
  option but that won't work because there is no more hiDPI support and
  dual display doesn't work.

  This has been ongoing for several weeks, around the 4.12 kernel.
  Please fix it. It would be a shame for this product not to boot Artful
  out of the box.

This bug shouldn't be fixed-released. Nothing got fixed. The live image
doesn't boot without the nouveau modeset kernel boot option. It
shouldn't be fixed until the live image boots without any tinkering.

[Anmar Oueja]

I just tested the "blacklist=nouveau modprobe.blacklist=nouveau" and the
"nouveau.modeset=0" separately and both of them the machine booted off
the USB stick. I had a live image running 4.12 kernel so I will test
today's images (with 4.13 kernel) and report back.

Here is  my dmidecode just in case anybody wants to confirm the type of
machine I am testing on especially that some of you couldn't boot it
with the above modeset mods to the kernel boot prompt.

Re: [Kernel-packages] [Bug 1718936] Re: Can't boot Artful 17.10 live images on XPS 15 (9560)

[Anmar Oueja]

I did that with yesterday's Ubuntu 17.10 live image and it did boot.

Q: Does that mean the acceleration is done by the Intel board instead?

[Kernel-packages] [Bug 1718936] [NEW] Can't boot Artful 17.10 live images on XPS 15 (9560)

[Anmar Oueja]

Public bug reported:

I usually test Ubuntu beta releases. With Artful, I haven't been able to
boot the image on my XPS 15 (9560) Dell laptop because the boot process
stops half way.

The boot proceeds properly if I pass the "nomodeset" kernel boot option
but that won't work because there is no more hiDPI support and dual
display doesn't work.

This has been ongoing for several weeks, around the 4.12 kernel. Please
fix it. It would be a shame for this product not to boot Artful out of
the box.

Title:
  Can't boot Artful 17.10 live images on XPS 15 (9560)

Status in linux package in Ubuntu:
  New

Bug description:
  I usually test Ubuntu beta releases. With Artful, I haven't been able
  to boot the image on my XPS 15 (9560) Dell laptop because the boot
  process stops half way.

  The boot proceeds properly if I pass the "nomodeset" kernel boot
  option but that won't work because there is no more hiDPI support and
  dual display doesn't work.

  This has been ongoing for several weeks, around the 4.12 kernel.
  Please fix it. It would be a shame for this product not to boot Artful
  out of the box.

[Kernel-packages] [Bug 1697556] Re: Computer freezes after login - 4.10.0-22-generic

[Anmar Oueja]

I just checked the the 17.10 live images on my XPS 15 (9560) and the
kernel still doesn't boot without using "nomodeset" kernel boot arg.

  Computer freezes after login - 4.10.0-22-generic

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have got a new Ubuntu 17.04 install on a Dell XPS 15 (Intel(R)
  Core(TM) i7-7700HQ CPU @ 2.80GHz) that was installed a couple of days
  ago. Login worked fine too.

  A couple of days later I installed the suggested kernel update
  "4.10.0-22-generic". With kernel 4.10.0-22-generic, the computer
  freezes right after login (i.e. after pressing enter, the background
  image with the mouse is shown, no responses to any key strokes).

  Note, this problem is observed with kernel 4.10.0-22-generic whereas it's not 
observed with 4.10.0-21-generic. As I was not able to login to my computer I am 
writing this bug report while it runs on kernel 4.10.0-21-generic. Therefore 
the information attached through the "ubuntu-bug linux" command here, are 
referring to the kernel that is actually working. I decided to nonetheless 
include that information as it might contain other kernel unrelated information 
that would help you troubleshooting.

Re: [Kernel-packages] [Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Anmar Oueja]

Have you guys tried uninstalling the Intel Xorg driver so you default
to kernel mode settings. That solved a lot of flicker issues for me.

$ sudo dpkg --purge  install xserver-xorg-video-intel

Guys, there is an entry on the Chromium site talking about xorg modesetting
vs intel xorg driver. By installing modesetting module and getting rid of
the intel driver, the flicker was gone completely on Ubuntu 16.04.

Yikes. In your case it isn't the browser for sure. I read somewhere that
the adaptive brightness control might be a culprit but don't count on that
being true unless confirmed.

Chrome flickers... but FF doesn't for me. Are you sure it isn't the
browser.

[Kernel-packages] [Bug 1572723] Re: Dell XPS 9350 Reboots upon resume with the latest 4.4.0-21 kernel update

[Anmar Oueja]

I have tested the following kernels:

4.6.0 - Works on resume without any problems. Zero failure rate
4.6.1 - Doesn't boot to lightdm. Erro with udev. Ignore it for now
4.6.2 - Boots but resume is the same problem. When I resume the laptop, the 
machine restarts. Could be i915. Not sure.

[Kernel-packages] [Bug 1572723] Re: Dell XPS 9350 Reboots upon resume with the latest 4.4.0-21 kernel update

[Anmar Oueja]

I just booted windows and re-applied the new BIOS (1.3.3) and the new
Thunderbolt Firmware so I am all caught up on the BIOS and firmware
settings on the board.

I also nuked all the HD and re-installed Ubuntu from scratch. I just
retested it and the crash still happens when you close the lid or issue
a suspend commend using the UI.

This is a critical regression that should be addressed and soon.

[Kernel-packages] [Bug 1572723] Re: Dell XPS 9350 Reboots upon resume with the latest 4.4.0-21 kernel update

[Anmar Oueja]

BTW, I did install i3 and tried it, to eliminate Compiz and the same
problem continues to happens so I am guessing it is the kernel and not
Compiz causing the problem (This issue happened but turned out to be
compiz last time I filed a similar report)

[Anmar Oueja]

I discovered that if you have tlp installed and running, you will get
screen flicker. If you disable it, or remove it, the flicker goes away.
Seems something to do with the power management and skylake.

[Kernel-packages] [Bug 1552304] Re: screen flicker on Dell XPS 13 9350 after kernel upgrade

[Anmar Oueja]

My BIOS is version 1.2.3 and the flicker continues to happen  even with
the -11 latest kernel update.  I just tested Ubuntu Gnome and the
flicker is gone. Interestingly , if you boot standard Ubuntu, with
unity, and spt-get install gnome-shell-session, then log out and log
back in the Gnome shell, flicker continues.

[Anmar Oueja]

I tried 4.5 kernel from the Canonical team PPA and it is still
flickering but to a lesser degreee. BTW, the flickering goes away when I
am on a video conference call such as google hangouts.

[Kernel-packages] [Bug 1291371] Re: thinkpad screen dims after unplugging external display, and won't re-brighten without leaving X

[Anmar Oueja]

I also confirm that problem continue to exists for Ubuntu 14.04 using th
standard Linux X1 3.13.0-30-generic #54-Ubuntu SMP Mon Jun 9 22:45:01
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux kernel.

The way around it is to go the console, adjust the brightness to desired
level, then go back to X.  Brightness adjustment doesn't work at all
when in X. Just console after I unplug the external monitor or reboot
the entire machine.

  thinkpad screen dims after unplugging external display, and won't re-
  brighten without leaving X

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  When I un-plug the external VGA cable from my Thinkpad X200s, the
  screen dims.  Hitting Fn-Home (the brightness-increase key) does
  nothing.  Suspending and resuming doesn't reset this, though a reboot
  will allow me to use the brightness controls again while in the POST
  and after.

  My current workaround is that every time I disconnect the monitor, I
  have to C-M-F1 to get to a virtual console, brighten the screen, and
  then M-left to get back to X.

Re: [Kernel-packages] [Bug 1098216] Re: Regression in brightness control on Lenovo Thinkpad X230 (+tablet) and X1 Carbon

[Anmar Oueja]

I just tested it on my Thinkpad X1 (haswell) and the fix works.
However, there is a side effect. Connecting and Disconnecting the
Power resets the brightness to maximum.  Not sure how to go about
working around this.

[Anmar Oueja]

On 13.10, the brightness works fine but the stepping is screwed up. In
other words, you don't get to access all of the brightness levels the
LCD offers. Instead, you get half the number of steps. It isn't a show
stopper by any stretch so go ahead and get your X1 carbon. It is the
best machine out there ;-)

Re: [Kernel-packages] [Bug 1221790] Re: Screen brightness is maximum upon fresh boot

[Anmar Oueja]

I did upgrade the BIOS a few weeks ago when I was running 13.10.
Unfortunately, this didn't change anything. I am now running 14.04
with the latest apt-get and the results are the same.

 What happened?

Upon cold boot or restart, the screen brightness is set to maximum
even if my setting wasn't.

 Output of the command sudo dmidecode -s bios-version  sudo
dmidecode -s bios-release-date

G6ET99WW (2.59 )
11/19/2013

One thing I noticed is that when the machine boots and the lenovo
logo is displayed, the screen brightness is set to maximum, which
leads to believe that UEFI runtime services may not be setting the
brightness variable properly so it isn't persistent.

I just confirmed that the problem continue to exist using Linux X1
3.11.0-8-generic #15-Ubuntu kernel. The 13.10 system is updated as of
2013.09.21.

 indicate in the bug if this issue still exists or not.

 You can update to the latest development kernel by simply running the

 sudo apt-get update
 sudo apt-get dist-upgrade

 If the bug still exists, change the bug status from Incomplete to

 Thank you for your help, we really do appreciate it.

[Kernel-packages] [Bug 1098216] Re: Regression in brightness control on Lenovo Thinkpad X230 (+tablet) and X1 Carbon

[Anmar Oueja]

I installed Ubuntu 13.10 running 3.11 kernel and I noticed the stepping
is still there.  The following fixed the stepping:

sudo sh -c 'echo -n 0 
/sys/module/video/parameters/brightness_switch_enabled'

Seems that the driver and the GNOME settings daemon, or some other user
space tool,  is issueing the same command so it is doubling up.  Should
I open another bug or continue to use this bug?

[Kernel-packages] [Bug 1221795] [NEW] brightness stepping is incorrect (double what it should be)

[Anmar Oueja]

Public bug reported:

Problem:  When I press the laptop screen brighteness, each step yield an
event that is displayed on the OSD but the screen brightness doesn't
change until the third press. Same happens for decreasing or increasing
the brightness.

Exepcted behaviour: Each press of the brightness button on the laptop,
yield a visible change in the brightness of the LCD scree.

Workaround: This seems documented and works perfectly. The work around
is to type this in terminal:

sudo sh -c 'echo -n 0 
/sys/module/video/parameters/brightness_switch_enabled'

More details are here: http://askubuntu.com/questions/173921/why-does-

Re: [Kernel-packages] [Bug 1221795] Re: brightness stepping is incorrect (double what it should be)

[Anmar Oueja]

BTW, this command line option (acpi_backlight=vendor) fixes the
problem so I am now not sure if this is a bug or not.

 Title:
   brightness stepping is incorrect (double what it should be)

 Status in “linux” package in Ubuntu:
   Incomplete

 Bug description:
   Problem:  When I press the laptop screen brighteness, each step yield
   an event that is displayed on the OSD but the screen brightness
   doesn't change until the third press. Same happens for decreasing or
   increasing the brightness.

   Exepcted behaviour: Each press of the brightness button on the laptop,
   yield a visible change in the brightness of the LCD scree.

   Workaround: This seems documented and works perfectly. The work around
   is to type this in terminal:

   sudo sh -c 'echo -n 0 
   /sys/module/video/parameters/brightness_switch_enabled'

   More details are here: http://askubuntu.com/questions/173921/why-does-

   I think this should be fixed in 13.10.

Re: [Kernel-packages] [Bug 1221790] Re: Screen brightness is maximum upon fresh boot

[Anmar Oueja]

This didn't used to happen. I believe it started with the 3.11 kernel
since there is new code in that area. I will try installing 3.10 and
some early 3.11 RCs and see where I land.  I know where to get the
earlier kernel packages (kernel team PPA) but how do I interrupt the
boot process to tell ubuntu to run an older release. Everything is
masked by the Ubuntu logo boot now.
