Sent the gathered data to you and intel-gfx. Don't have e-mail addresses

OK.

Short story: bug still present.

Long story:

These kernel files were downloaded and installed...
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc2+cod1-wily/
total 56M
-rw-rw-r-- 1 contact contact   66 Nov 25 17:15 linux-4.4-rc2+cod1-wily.txt
-rw-rw-r-- 1 contact contact 745K Nov 25 17:13
linux-headers-4.4.0-040400rc2-generic_4.4.0-040400rc2.201511231054_amd64.deb
-rw-rw-r-- 1 contact contact  55M Nov 25 17:14
linux-image-4.4.0-040400rc2-generic_4.4.0-040400rc2.201511231054_amd64.deb

As ever, everything seemed OK when suddenly, when I was using the system in
Firefox, the screen became corrupted with junk and the mouse pointer
disappeared.

IDEA: Will try running system with Firefox set _not_ to use graphical
hardware acceleration.

BW,


Ian

Re: [Kernel-packages] [Bug 1514102] Re: Intermittent graphics corruption

[Ian Bruntlett]

Hi Christopher,

Good news! An Intel graphics specific kernel arrived and I installed it. So
far, the graphics are working fine. However, I must point out that more
testing is required.

Here are the details of the files involved etc:-

linux-headers-4.3.0-997-generic_4.3.0-997.201511202100_amd64.deb
linux-image-4.3.0-997-generic_4.3.0-997.201511202100_amd64.deb

Files from:-
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/

This error message whilst running sudo dpkg -i *.deb

Which kernel version specifically?

There is one now available for 4.4-rc2.

1. Even with that kernel, graphics problems are still present.

2. Will keep an eye out for the .debs of the kernel you'd like me to

Hi Christopher,

Spent a lot of today learning how to edit files using vim.

I could not find the kernel deb packages. I've looked everywhere I could
think of including:-
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc1-wily/

What would you recommend?

Also, you previously asked me to try testing drm-intel-nightly and I have
the same problem - can't find .deb packages is here:-
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/

My weekend is clear so, when you pass on the info about the kernel deb
files, I should be able to get back to you a bit quicker :)

BW,


Ian

[Kernel-packages] [Bug 1514102] Re: Intermittent graphics corruption

[Christopher M. Penalver]

Ian Bruntlett, if they don't exist, then usually one has to wait for
them to populate, or until the next kernel release (which will populate
drm-intel-nightly also).

Apologies - the results I gave you were for without the workaround.

Does this mean you want me to test a kernel from here:-
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/

I'm a bit busy at the moment but I may have some results for you on
Wednesday night.

BW,

Ian

Re: [Kernel-packages] [Bug 1514102] Re: Intermittent graphics corruption

[Ian Bruntlett]

Squeezed in a bit more work today...

1. Tried kernel 4.3.0 today (the one you recommended me a few e-mails ago)
with the "nomodeset" parameter and the graphics system went into 640x480
mode, couldn't change it from the desktop. However, the graphics _worked_ :)

2. Viewing menus in GRUB. Did this in /etc/default/grub:-
GRUB_TIMEOUT=-1
commented out GRUB_HIDDEN_TIMEOUT with a '#'
Now I can choose which kernel to boot from :)


Ian

That's quite worrying as a fair number of my friends use 32 bit CPUs.
However, to be more accurate, they tend to be some kind of Pentium or Atom.
Will the 586 CPUs still be supported in future releases of  Lubuntu Linux?

OK, done that.

Short story: Bug still present.

Also, try as I might, I couldn't get a boot menu listing the different

HTH :)

Is there anything else I can do for you?

BW,


Ian

[Kernel-packages] [Bug 1514102] Re: Intermittent graphics corruption

[Christopher M. Penalver]

Ian Bruntlett:

>"BTW, the PC in question was originally running (32 bit) Windows XP. As
we are experiencing problem with graphics when running 64 bit software,
perhaps I should install Lubuntu 15.10 i386 and see if that works?"

While you are welcome to do that as a test (as the release and
architecture are supported downstream via the L/Ubuntu Community), it
wouldn't be recommended to use a i386 architecture going forward as it
is deprecated upstream.

Despite this, 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 your understanding.
