monitor off after grub

[Markus Mitsch]

on my main machine the monitor shuts off after grub, but the system boots in background. the monitor wont come back on so i have to power it completely off and on again. if i do this early enough i can see the glowing kubuntu logo. i tried various "video=" kernel options among other things but with no success.

WORKAROUND: Edit /etc/grub.d/10_linux and change:
vt_handoff="1"

to:
vt_handoff="0"

then do sudo update-grub and restart.

the output of the commands:

Markus Mitsch, did this problem not occur in a release prior to 15.04?

[Markus Mitsch (markusmitsch86-m)]

i feel a bit stupid as i now found out where this comes from and i didnt try that before. my linux boot command line included "$vt_handoff". removing it made everything work as expected. so it is definitly not a kernel problem i think.

Markus Mitsch, just to advise, having to remove the vt_handoff kernel parameter would still be considered a bug. However, if you wouldn't like this issue investigated and fixed so you don't have to remove vt_handoff, then Invalid would be the appropriate status as defined in https://wiki.ubuntu.com/Bugs/Status .

[Markus Mitsch (markusmitsch86-m)]

ok, so i my final workaround is editing /etc/grub.d/10_linux and changing the line vt_handoff="1" so that it reads vt_handoff="0". then a sudo update-grub and it works without editing the command line every boot.

Markus Mitsch, 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 XY 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 upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.
