Comment 9 for bug 1550893

Same problem here, even worst. As soon as webbrowser starts it can freeze the desktop screen, keyboard and mouse.

1) At first I was able to login with a second system (or a smart-phone with ssh) and reboot the system, but now not even this works.

2) Amazon and other "channel" web apps depends on this so I am afraid that any Web apps that uses this can freeze the system "without notice".

3) looking at the syslog/auth.log, other than some hardware conflicts I already had before, I can't spot any traces of what is causing the problem. I suspect only this in auth.log:

lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory

lightdm: PAM adding faulty module: pam_kwallet.so
lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "jxxx"

4) My system has this configuration:
