[Bug 667725] [NEW] old framebuffer contents show momentarily on reboot

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

When I boot my computer, between plymouth and gdm, there is a momentary
display of the contents of the framebuffer of the end of the last
session. This generally won't happen if the last shutdown was normal, as
it's probably a blank screen or something. There are a few conditions
for this to happen:

- using nouveau driver with KMS
- it helps if the VTs are using the same resolution as X (using vga=) so that resolution change doesn't hide it
- happens the most on hard reboots like SysRq+B

So basically, what I mean is that, say I had, a picture open, and I hard
reboot my computer, I will see the contents of my screen, with that
picture, between plymouth and gdm.
