Hope someone can help me with this unusual problem. I installed Ubuntu 12.04 server on a Gigabyte GA-H61M-USB3 motherboard. This all went well. I subsequently installed Apache, MySQL and PHP. This also went well. I am using the UFW kernal firewall instead of the recommended Shorewall (could not find the repository during installation). I thought I had a working server until I relocated the box and attempted to log in using PuTTY. Turns out that the server does not boot without a monitor and keyboard connected. I don't believe there is anything in the motherboard that is preventing the boot. Has anyone else seen this behavior and what was your fix. Thanks.


Have you verified that the system does not boot? For example add something like


to /etc/rc.local and check that file after reboot.

Are you using the correct IP to connect via Putty (static vs dhcp configuration)?

  • Yes, it is not fully booting. I don't know how far into the boot process it is getting to before it fails. I can try your suggestion to be sure. When I reconnect the monitor and keyboard it works fine. I am using a static IP in the server. PuTTY works fine when attached to the monitor and keyboard through a KVM switch. – jim Apr 30 '13 at 12:37
