Date: Tue, 2 Jun 2015 22:45:47 +0200 From: Luis Rocha <luiscrocha@...il.com> To: john-users@...ts.openwall.com Subject: Re: Multiple GPU and Fork I'm running Ubuntu 14.04.2 LTS and In this case I had X running. So, I disabled the x11-common service and added the line GRUB_CMDLINE_LINUX_DEFAULT="text" to /etc/default/grub. Upon restart the system does not start X. I launched JtR, but the same behavior. Interesting, without X, JtR is slower starting ... on a different topic not having X breaks oclHashcat1.36 - ADL_Overdrivev5_CurrentActivity_Get() Any other things I could try? PS: I am running this version of Ubuntu and Cat Driver (14.9) in order to have the latest oclhashcat capability.
