Public bug reported:
This is the first time I've used the Nouveau driver as this is really
the first time I've felt it good enough to use full time (I haven't
tried it since 10.04). But now that I've done a brand new install of
Precise on my Alienware M15x with the nVidia GT240m GPU, I'm running
nouveau.
It's not a major issue, but I do see a lot of garbage, presumably left
over in video ram when I log in to Ubuntu. This goes away after several
seconds (somewhere between 5 and 10 seconds) but A: it looks very
concerning when it happens, and B: if you look close enough, it's
possible that someone logging into the system could catch snippets of
private information as it's dumped to the screen between hitting enter
on lightdm (after entering the password) and the desktop fully loading.
So there's a very slight security/privacy concern there.
I am not sure what causes this, I'm thinking it's cached or left over
vram data perhaps, but the person logging in will get to see bits and
pieces of previous desktop sessions, including text, pictures, etc.
So on the one hand, it looks scary, and may be daunting and provide bad
associations to new users with similar hardware, and on the other hand,
as mentioned above, there is a slight concern for privacy and security
if someone else is logging onto the machine and getting to see bits of
the last person's desktop.
