Make X calls synchronous
I am not sure if it is about this
Normally a mobile phone is synchronized with an OS and not only a browser but repo might be right
For the login screen some versions and distros have special knobs at the desktop menu called users/groups and similar
There are checkboxes for login for root, admin and so on
The minimum login ID has to be set to 0 for normaly root ID is 0
But it might become 7777 in future
And for more explanation: first non-root user might become 10,000+
But I can also imagine chars, neg numbers (lol for lot of light)
/etc/nologin disallows logins
/etc/pam.d/login pam(8) configuration file
builtin(1), chpass(1), newgrp(1), passwd(1), rlogin(1), getpass(3),
I have to say further I havenīt used login command before just the Xserver desktop environment menu users/groups button at CrunchBang 8 (Ubuntu based) and that worked for me
The smaller LiveCD might be limited and is also available for several desktop builds at http://fedoraproject.org/de/get-fedora-options#desktops
Furthermost I have to add that I have no experience to sync a mobile phone with a computer nor any knowledge about linux OS on mobile phones
and if the browser crashes it simply crashes mostly by overload, no swap, little ram and such like.
I decided to have a short look on a distro and when its getting difficult than let this version be because there often is more to come!
I think I`ll stay with *Pup* 4.3.1 for 5. is said to be Ubuntu based.
All the best and much luck!
