When I restart my computer and log in gnome, I'm getting following error :
Could not look up the internet address for host_xxxx this will prevent GNOME from operating correctly. It may be possible to correct the problem by adding host_xxxx to the file /etc/hosts
I tried to add a hostname to the file /etc/hosts but nothing changed cause I'm using a USB modem and every time I restart my computer, I'm getting an IP and hostname from the DHCP server.
How can I solve this problem?
