Which groups are those? Maybe the problematic user does something during
X startup which the new user cannot do.

The warnings should not keep the X server from starting. The last error
is to be expected with the vesa driver and not critical AFAIK.

That looks like it is really the X server that crashes and not a user
process. I think Micheal was on the right track when asking about the
detailed group memberships of the two users.

Yes, it looks like the Chrome 9 support might still take a while:

No obvious problem here. Grasping for straws, you could try if disabling
"ShadowFB" and/or "ModeSetClearScreen" makes a difference (see "man
