Well, that was an hour of my life I'll never get back. Installed it on a spare bit of hdd on the Sony VGN A197VP lappy. Obvious problems:- Brightness/volume/zoom/soft DVD eject buttons do nothing. Hardward graphics acceleration missing. Now I might have been content to sit there playing round browsing and downloading shit trying to fix stuff but for the biggie:- touch pad absolutely useless, the cursor only responds when it wants to, most of the time doing nothing until I wiggle finger round trackpad like mad, then it moves, for a second, then back to being dead. I'll leave it to fester until I see someone has a fix. Or clobber it and put something else interesting [1] on. [1] Interesting from the point of view of a geek who likes fiddling with stuff and getting things working, but doesn't like things being *that* frustrating.
