I am using Ubuntu Server 12.04 in a virtual machine (VMware Workstation) and it seems like the system goes to standby, at least the first request on a webserver installed on it takes quite long and the "virtual monitor" goes to standby.
How can I disable this sleep mode?
Please note I alraedy searched for this problem and had a look at Ubuntu Server goes to standby mode, however that didn't help in my case ): Thanks for any hint!
