switches to text VT before/after suspend

[Martin Pitt]

Binary package hint: pm-utils

Since recently, when I activate suspend, it switches to VT1 first, suspends, wakes up on VT1 again, and switches back to X. It is meant to stay on X all the time on a recent KMS system (i. e. if we do not have the "change VT" quirk).

I can't reproduce that any more.

[Chow Loong Jin (hyperair)]

I'm confirming and shifting to linux. This happens with kernels from Karmic's version upward to 2.6.34. pm-utils doesn't do any quirk, but i965 internally shows tty1 for a brief moment before suspending/resuming. If suspend/resume hangs at the kernel level, then it hangs showing tty1.

I had the same issue, it's usually unnoticeable with KMS due to how fast VT switching is, but it actually does VT switch on suspend at the kernel level. If you have an external display connected or one of the pm-utils hooks is taking awhile to complete for instance it's a lot more noticeable.

Martin Pitt, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

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.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Please let us know your results. Thank you for your understanding.
