[Kernel-packages] [Bug 1251580] Re: Display is heavily distorted after kernel upgrades
The solution I used (as an idiotic layman) was to upgrade (instead of downgrading) the kernel to a version =3.15 by using the deb files which may be found at http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D Pick a subdirectory with high enough version (e.g. v3.15.3-utopic/ ). You need 3 .deb's from that page: the headers-all package and the image and headers packages appropriate for your architecture (presumably x86_64 if you are using the same Optiplexs as above). Download the .deb's and install them by typing (from the directory where you downloaded them): sudo dpkg -i linux* Even if this version is not intended for the distribution I had, it still worked perfectly (my distribution was a quantic and the kernel says it goes for utopic). You do not need to reinstall anything. From the post mtornos made on the Ubuntu forums, I gather it worked for him too. This update will (but again I am speaking as an idiotic layman, so maybe it won't) be automatic at some point: the kernel version keeps being updated via official updates. For example, on my other computer I am now at kernel 3.13 by just keeping to the official updates. The problem is that you might have to wait for a year or two before it reaches 3.15.x, unless you do not do it manually. -- 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/1251580 Title: Display is heavily distorted after kernel upgrades Status in linux package in Ubuntu: Triaged Bug description: The bug is present already at boot (even from a USB stick boot without installing) in all Ubuntu (and variants) relying on Linux kernels 3.10 to 3.12 (- still present in 3.13).

Is there any progress on publishing a fix to this in the lts-trusty HWE for precise (or alternately providing lts-utopic for precise)? This is currently an issue for some systems I am supporting. Downgrading them to a 3.11 kernel or changing distributions is not currently an option for me, and it looks like lts-utopic is not available for precise. -- 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/1251580 Title: Display is heavily distorted after kernel upgrades Status in linux package in Ubuntu: Triaged Bug description: The bug is present already at boot (even from a USB stick boot without installing) in all Ubuntu (and variants) relying on Linux kernels 3.10 to 3.12 (- still present in 3.13).

Antoine, unfortunately I couldn't speak to mainline-build-one, as I frankly don't use it when bisecting, and I didn't write that section.

Dear Christopher, I made a mistake by not quoting precisely enough the machine type: 41R66X1 This is(are) an Optiplex 9010 AIO (All-in-one) and was the reason for the strange error message Cannot update a OptiPlex 9010 with a BIOS for OptiPlex 9010 from my previous comment. I made the BIOS update to the latest available on http://www.dell.com/support/home/us/en/19/product-support/servicetag/41R66X1/drivers namely version A15. The bug is intact and persists; nothing changed. The output of sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date is A15 05/05/2014 Please keep me posted on what I could do further.

[Kernel-packages] [Bug 1251580] Re: Display is heavily distorted after kernel upgrades
Antoine, could you please test the latest upstream kernel available (the one all the way at the top, and not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.15-rc8 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

The leftmost part of the screen remains legible as the distortion effect is smaller there but the rightmost part is impossible to read. A straight vertical line looks like sine wave, the time frequency of this wave varies with time, the amplitude is always increasing linearly as one moves to the right of the screen.

Dear Christopher, many thanks for your help and (probable) identification of the problem. I tried to follows the instructions for the various option to install the update via FreeDOS. I can run the update .exe (obtained from the Dell website) but then I get the error message Cannot update a OptiPlex 9010 with a BIOS for OptiPlex 9010 Do you have any other suggestions on how to make those update package run (without installing windows)?

For non-correctly-displaying computers: dtiming: 1920x1080@68 For correctly-displaying computers: dtiming: 1920x1080@60 For the record, there is no other ctiming or dtiming line in the output of ddcprobe. The configuration are otherwise strikingly similar. The other differences which seemed of significance (i.e. not mentionning hard drives partitions and serial numbers) is that uncorrectly working computers have the following extra line in lspci 00:16.3 Serial controller: Intel Corporation 7 Series/C210 Series Chipset Family KT Controller (rev 04) Correspondingly, the lshw of these computers have the following extra section: *-communication:1 description: Serial controller product: 7 Series/C210 Series Chipset Family KT Controller vendor: Intel Corporation physical id: 16.3 bus info: pci@:00:16.3 version: 04 width: 32 bits clock: 66MHz capabilities: pm msi 16550 bus_master cap_list configuration: driver=serial latency=0 resources: irq:19 ioport:f0e0(size=8) memory:f7d3a000-f7d3afff Lastly, in the *-pci section. Also, the *-memory *-bank:n (for n an integer) are not of the same vendor (Samsung or Nanya technologies for correctly-displaying computers and Hynix/Hyundai for non-correctly- displaying ones). The visual distortion is roughly as follows: every line gets horizontally enlarged by a factor t. This factor varies with time and with the height of the line to make nice sine curves out of straight vertical lines. Actually there is a phase difference between even and odd lines. The leftmost part of the screen remains legible as the distortion effect is smaller there but the rightmost part is impossible to read. A straight vertical line looks like sine wave, the time frequency of this wave varies with time, the amplitude is always increasing linearly as one moves to the right of the screen.
