I tried the 295.59 today, login fine, dual monitors fine.
Also keeping in mind that my test user account logs in fine with 302, and dual monitors are fine, and no flickering occurs as I assume xrandr is run. I'll search for xrandr in my main user . files.
When in 295.59 I get this:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 2560 x 1024, current 2560 x 1024, maximum 2560 x 1024
default connected 2560x1024+0+0 0mm x 0mm

I have to also note I am still using kde 3.5.9, never changed to kde 4.x, yet anyway. 302.xx shows each monitor resolution by the way, not the total as it did previously.
I'll post the xrandr for the 302 for the user that works and the main user account a bit later, have to do some work stuff now.
