[Bug 1441305] Re: Stuck with black screen on boot (no signal)
** Description changed:
Recently, the following problem appeared suddenly:
- Start computer
- Ubuntu splash screen appears with dots
- Screen turns black and switches off (no signal)
This happened on every boot. Previously I had removed all but the latest
kernel [linux-lts-trusty (3.13.0-48.80~precise1]), but this may be a
coincidence because that kernel started without problems before.
Note 1: My OS starts from an SSD.
- Note 2: The same problem also appeared at the same time on Ubuntu 14.04 LTS 64 bit installed on a different SSD on the same computer. However, there the black screen only appears on every *first* boot. The second boot will be fine.

I could not even start my computer in recovery mode, as it hung after
mounting additional HDDs (may be related or not). In the end I was able
to start it in text mode by adding "nomodeset" to the GRUB boot options.
Switching the display manager to gdm then fixed the problem for me.
