I've searched and haven't seen this posted anywhere else, perhaps it's something wrong on my end. So I burned the most recent BT3 beta and booted up off the live cd. Upon loading KDE the toolbar is about 2/3 from the top of the screen just kind of floating around, and it doesn't extend all the way across the screen. The screen is 15.4 and it looks like the right resolution was set (1680x1050) but the desktop itself is limited to 1024x768, which is the highest I can set it to in the Configure Desktop properties. I can also drag windows and programs around the outside of the toolbar and it's not like they disappear. Any ideas?
UPDATE: Fixed, I changed the option for Xinerama from '1' to '2' and it seemed to position the bar correct.
Yeah you could also have tried to boot in VESA mode i think, seeing as it looks like
you are using a kind of wide screen or am i wrong? I've seen similar problem once which
needed the VESA boot instead in BT3.
