Filed under
HowTos

Even if you boot in single user mode it will ask root password for maintenance, and just imagine you do not have a backup of /etc/shadow file. How will you fix such problem in a production environment where time is critical factor? Relax here I will explain how to recover deleted /etc/shadow file in five easy steps. It will take around 10 min. to fix problem.

  • The Best Graphics Card Brands For NVIDIA/AMD GPUs As A Linux Consumer?
    One of the most frequent topics I'm emailed about is any brand recommendations among NVIDIA and AMD AIB partners for graphics cards. For Linux users, is there a particular brand preference for graphics cards? The short story is, no, there isn't one particular brand when selecting either a GeForce or Radeon graphics card that a Linux gamer/enthusiast should go with over another AIB partner. Over the past 12 years of running Phoronix, there has been no single AIB partner that superbly stands out compared to the rest when it comes to graphics card AIB partner brands like ASUS, Zotac, HIS, MSI, etc. They all work under Linux, rarely the AIB differences extend beyond the heatsink/cooler and any default clock speed differences, and I haven't seen one that's over-the-top crazy about Linux. I also haven't seen any major partner consistently put the Tux logo or other Linux markings on their product packaging, let alone incorporate any Linux drivers onto their CD/DVD driver media.
