Marien Zwart, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test 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. 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-v3.11

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.

Title:
  viafb and vga16fb turn off lcd on an acer aspire 1350

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading from karmic to lucid my laptop turns off its lcd panel
  early during boot, after which I cannot figure out a way to turn it
  back on. X starts (I can hear the gdm drums and log in blindly), I can
  ctrl+alt+f1 out of X and alt+f7 back into X, but during all this I get
  no output on the screen. Blacklisting the viafb module gives me a
  garbled framebuffer. Blacklisting vga16fb too makes everything work.

  Fixing this is a little annoying because just disabling X still does
  not give you a working shell (I used a rescue cd to edit
  /etc/modprobe.d/blacklist.conf). So it might be nice to fix this
  before lucid is released, even if it involves disabling viafb on more
  systems than strictly necessary.

  I'd be happy to test any patched kernel images that might avoid this
  bug.
