hello everyone ,I have some problem in starting qt4 designer,when I start it in root ,it shows:
"session management error,Authoentication Rejected,reason:None of the authentication protocols specified are supported and host-based authentication failed"
but when I start it in normal user,everything is ok except that I can't input chinese,though I can do it in my program.
