It is installed But I checked ymessenger was not the problem for X crash.
Well, I suspect ymessenger is the culprit, for some reasons it created a blank .xinitrc.
yaa ymessenger was the culprit (philip has given the same reason yesterday and I have tested). ymessenger creates blank .xinitrc file in home directory. and That was the problem.
Is the problem related to SUSE only?Becoz i had installed yahoo on my gentoo sys.It worked fine.
