I wanted to test the latest Ubuntu builds to see if there are any improvements for my Poulsbo hardware in the latest kernels, and it seems that I've struck a rather nasty regression. I tried three Ubuntu images so far, and the two latest ones don't even boot on my machine.
When I attempt to launch the LiveCD, the screen turns off and no input is accepted. Unfortunately, that also makes is difficult to find out what goes wrong. I even tried booting into runlevel 3, and it didn't help, either. All I can see is the first two lines that appear when I try to launch the LiveCD, and just when the VGA mode is about to be set to a new value, the screen goes dark, with no input being accepted.
I tested Alpha 3 and today's daily build, and both have this problem. On the other hand, Alpha 1 works just fine (or, well, as fine as it gets on this hardware so far).
The machine I'm testing this on is a Fujitsu Stylistic Q550 tablet, an Intel Oak Trail device. Since the graphics chip has always been trouble on these devices, I suspect that this problem has to do with the kernel updates, but then it strikes me as odd that it would fail like that even when I'm attempting to boot to runlevel 3.
Anyone else having this kind of a problem? Any way to find out what exactly is the cause of it? I guess I'll also try Alpha 2 and see if it worked or not, and perhaps the betas of other distributions, to see if the problem may be related to userspace after all.
EDIT: Apparently, Alpha 2 is no longer available. Hmm.
