Public bug reported: 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.
