Graphics freakout upon logout on Intel 5500 (Broadwell GT2)

[Daniel Convissor]

Got a new Lenovo x250 with HD Graphics 5500 (Broadwell GT2). Installed 15.04 ISO downloaded about a week ago. On a default install (which uses Unity, I imagine) had a situation on several occasions when logging out of an account or shutting down the computer, the graphics go berserk. The display rapidly cycles from right to left, like an old TV that's out of alignment.

Cool, a new BIOS. Looked for one when I first got the machine. 1.15 came out subsequently. Installed the new BIOS with the help of geteltorito. Here's the output you asked for. Thanks Christopher.

The problem persists.

[penalvch (penalvch)]

Daniel Convissor, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test 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 bug 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 this bug, 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 bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.
