Title:
10de:08a2 Screen corruption on Macbook Air (Nvidia 320M)
Status in Linux:
Invalid
Status in linux package in Ubuntu:
Invalid
Bug description:
Binary package hint: xorg
I just got a Macbook Air and tried to install Ubuntu on it. Booting
up the main install disk resulted in some crazy screen corruption, and
the left inch and a half or so was completely useless, since it did
not appear to update other than randomly moving bits (described
below).
It is hard to describe. It looked as if I had a normal desktop, but
overlayed on top of it was a series of 3cm vertical 'bands'. There
was a staircasing effect between bands, as a small horizontal line
connected them but fell between successive bands. On top of all this,
pixels seemed to 'move' awkwardly, like they were dancing around after
too many beers. If I had to guess, I would say my video card and
display device disagreed on the resolution, and on top of that
somebody Snow Crashed my desktop.
Switching back to the console via ctrl-alt-f1 does not fix the
problem; my console was messed up in similar ways, though it looks
more like just plain Snow Crash then. There was no color in the
console, of course, so I guess it just must be hard to see any banding
artifacts, even if they are still there.
I guess is the wrong place to mention it, but as a side note: the xorg
folks semi-recently made "DontZap" the default, i.e. disabled ctrl-
alt-backspace. Please make it the default on Ubuntu, it's a real pain
to debug this kind of thing when you can't kill X.
The fix is simple: remove "quiet splash" from the grub boot lines.
Everything works then -- with both the nvidia proprietary drivers and
nouveau.
It might be important to note that my screen seemed fine until X
started up, so it seems to be some poor interaction between the splash
screen (I guess) and X's KMS?
This is 10.10, maverick. I didn't try an update after installing from
the CD, because it was too difficult to see what I was typing.
