Hi Folks: I've got an weird problem: When one of my physical interfaces are up, firefox starts but seems not connecting to X, so it isn't shown. Any tip or way to debug this problem ? My interfaces: 02:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02) 02:03.0 Network controller: Intel Corporation PRO/Wireless 2915ABG Network Connection (rev 05) Ethernet: # cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=dhcp HWADDR=XXXXXXXXX :) ONBOOT=yes TYPE=Ethernet USERCTL=no PEERDNS=yes IPV6INIT=no NM_CONTROLLED=no # cat /etc/sysconfig/network-scripts/ifcfg-eth1 # Intel Corporation PRO/Wireless 2915ABG Network Connection DEVICE=eth1 ONBOOT=no BOOTPROTO=dhcp HWADDR=XXXXXXXX NETMASK= DHCP_HOSTNAME= IPADDR= DOMAIN= TYPE=Wireless ESSID=MYONE CHANNEL=6 MODE=Master RATE=Auto USERCTL=no IPV6INIT=no PEERDNS=yes NM_CONTROLLED=no firefox-2.0.0.10-3.fc8 xorg-x11-server-Xorg-1.3.0.0-40.fc8 kernel-2.6.23.14-107.fc8 Thanks a lot in advance Lucas Brasilino
