[Bug 1053269] Re: black boot
@Lucazade- Thanks very much for reporting this regression. We're reasonably sure that the problem was introduced by one of the two backlight patches which were included in the 3.5.0-15.22 kernel. I've prepared two new test kernels -- each has just one of those patches applied: http://people.canonical.com/~kamal/lp1053269/patch1only/ http://people.canonical.com/~kamal/lp1053269/patch2only/ Please try both of those test kernels, and let us know which one causes the problem. (Its not likely that the problem will occur with both, but please do test both to confirm that). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1053269 Title: black boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1053269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1053269] Re: black boot
@Kamal: tried both kernels you provided but unfortunately none of these works.. still a blank screen from post-grub to X.. no VT or plymouth are visible. tried again the -21 release just to be sure it always work and it is ok.. let me know if I can provide any log to debug it better! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1053269 Title: black boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1053269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1053269] Re: black boot
@Lucazade- I'm very surprised that neither of those fixes it! For each of those test kernels (patch1only and patch2only), please install and boot that kernel, capture the output from 'dmesg' , and post that here. Also, please clarify exactly what happens... Are you saying that the black screen occurs post-grub, and then it *stays* black even after it has booted up all the way to the X login screen? Or are you saying that the screen goes black during the boot sequence but then lights itself up again at some point? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1053269 Title: black boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1053269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1053269] Re: black boot
i'll gather both dmesg and paste it here asap ;) I'm saying that the screen goes black during the boot sequence (just after grub) but then lights itself up again at lightdm (so when X goess up) In that black period I don't see the usual plymouth splashscreen neither i'm able to switch to any virtualterminal to see what is happening.
