monitor says "SIGNAL: NOT VALID" during boot up process

[klerfayt]

SIGNAL: NOT VALID
CABLE CONNECTED OK
92.6KHZ 58HZ

Is what I see on the monitor during the entire Xubuntu boot up process, although shut-down is fine and visible all the time.

monitor is DELL P790

if it helps then I can attach an old xorg.conf file

[klerfayt (klerfayt-deactivatedaccount)]

Just for clarification - I do not use xorg.conf at all as is default behaviour in Ubuntu Oneiric Ocelot

[klerfayt (klerfayt-deactivatedaccount)]

Workaround is to edit /etc/default/grub like this:

GRUB_CMDLINE_LINUX_DEFAULT="vga=normal nosplash"

GRUB_GFXMODE=1024x768

klerfayt, 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 images are available from http://cdimage.ubuntu.com/daily-live/current/ .

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 (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine 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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

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

As well, please remove the tag:
needs-upstream-testing

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.
