8086:2772 Intermittent graphics corruption without nomodeset

[Ian Bruntlett]

Every so often the screen would be corrupted with horizontal lines of junk.

WORKAROUND: Add to /etc/default/grub GRUB_CMDLINE_LINUX:
nomodeset

sudo update-grub
reboot
Now the system will only allow VGA 640x480 graphics.

No problem. On occasion I get confused as to which web page to do things on
but the lubuntu mailing list there are people who help me. You see, I have
schizophrenia and sometimes get a little confused.

Thank you for your patience.

I did this on "newton" computer.

And thank you for the link to the BIOS upgrade page...

There were 3 files listed for BIOS updates. I downloaded them all
1. BIOS update
2. Processor microcode update
3. Business Desktop BIOS utilities

I opened the BIOS update (1) in Archive Manager, it was called sp4423.exe.
I tried to extract a file from a folder within the exe file. It failed with
an error. Tried again, extracting everything to a sub-directory. It worked.

Went to the BIOS CD sub-directory and burnt a CD-R with the contents of
7D1_0161.iso

I did this on HP Compaq dc 7600 PC (hostname : aristotle).

* Booted PC from the BIOS update CD-R
* Got into the BIOS and flashed the BIOS

Updated. Rebooted. Changed GRUB_CMDLINE_LINUX to "". Rebooted. Back into
nice graphics. All I need to do now is use the computer for a while and see
if the graphics horizontal line problems have been fixed.

BW,

Ian

Hi,

To test this PC I reinstalled lubuntu 15.10 64-bit and used Synaptic
Package manager to install a few bits and pieces.

The PC is behaving much better now and graphics are OK.

Just in time to be given away to a friend who's PC's hard drives has failed
:)

Ian

PC graphics are still misbehaving.

One day I will know enough about Linux to be able to debug graphics drivers.

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? Someone.
somewhere may be misusing pointers leading to junk on screen.

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.

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?

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.

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 :)

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 :)

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).

[Ian Bruntlett (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.

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 test.

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.

Ian Bruntlett, to clarify https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1514102/comments/37 , was this tested to work without nomodeset?

Yes. In VGA mode (nomodeset present) the graphics were OK. Without it
(higher res mode), the graphics corruption occurred.

Ian Bruntlett, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate venue (TO: Daniel Vetter and Jani Nikula CC intel-gfx)?

Please provide a direct URL to your newly made report when it becomes available so that it may be tracked.

Thank you for your understanding.

Sent the gathered data to you and intel-gfx. Don't have e-mail addresses
for Daniel Vetter or Jani Nikula. Let me have them if you want me to pass
the report to them as well.

To advise, their email, and advice to do so, was provided in https://wiki.ubuntu.com/Bugs/Upstream/kernel :
"Please ensure you e-mail all maintainers of the driver in the TO: field, and CC the mailing list."
"A list of all kernel drivers and their maintainers may be found here."
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/MAINTAINERS

Also, please don't CC me on mailing list emails (instead post the upstream URL here as previously requested). Among many reasons, it gives the false impression that I'm going to swoop in and drop a code fix, I'm somehow a maintainer, or I advised you to do this (I advised sending TO maintainers CC list, not just e-mail the list).

OK, done that.

What is the upstream URL? Where and how do you want me to send it?
