Bug Description

Binary package hint: linux-source-2.6.15

If I turn off the monitor, linux doesn't boot until I turn it on again. The machine is very hot, with the fan at top speed, so it should be in a busy wait. I've waited up to 5 minutes without any result.

The kernel boots adding this option to the boot line:
video=radeonfb:ignore_edid

But then, when I turn on the monitor it can work only at 640x480. I've to reboot the machine to get it working at higher resolutions.

The solution is for radeon chips but I have a Intel 950 GMA chip which will have some other setting or might not support this option. Have someone solved this problem?

I can confirm that this also happens with gutsy. My project kind of hinges on my ability to un this computer without a monitor, so I hope there's a fix.

Boot Camp doesn't work without monitor: http://ubuntuforums.org/showthread.php?t=272967

It cannot easily be fixed by Ubuntu unless Ubuntu would get booted through elilo or grub-efi.

Maybe this is a feature request for the installer: Install efi boot loader on supported platforms.

Hi,
does that also happen with the latest Ubuntu developer version? You can download them at http://releases.ubuntu.com/8.04/

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Still no success. Ubuntu still doesn't use EFI to boot.

Hi akhilatmail,

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? Can you try 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 run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux-image-`uname -r` 173629

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
