It could also be the ROM itself, like if you downloaded it from the toolbox vs the website. Maybe the download from the ROM is the droid x one. Only one download for Liberty 2.0.1 shows up in the ROM. I just restored an old backup and I'm trying it again. If it doesn't work, I'm going to download it from the forum page.
I've tried the default launcher, adwlauncher, launcher pro, google sky map, the star wars 3d binoculars (the R2D2 app), and tricorder; all of which use the accelerometer and they all are messed up. For the camera, I've tried the google goggles, the camera app, barcode scanner, and a heart rate thing; all of which didn't work.
