As you may have noticed that there aren't much Gnome Shell themes in development now a days, this is because of quite fast development of Gnome Shell. But there are still some people who are working behind the scene to bring themes to make user experience much better with Gnome Shell. Aurora theme is kind of grayish color theme and it has two GTK versions one is complete gray and other one with dark title bar and there is only one Gnome Shell theme which is transparent. There are three versions of Aurora theme to support Gtk & Gnome Shell 3.12/3.14/3.16 versions, we've added all versions to PPA and version 3.12/3.14 available for Ubuntu 14.04 Trusty/Linux Mint 17.x/17 and Gtk & Gnome Shell version 3.14/3.16 available for Ubuntu 15.04/15.10 versions. This pack is works perfect under Gnome Shell and Cinnamon, and has some issues under other desktop environments such as Unity but you can still give it a try in other desktops. If you are using other distribution you can directly download theme and install it manually. You can use Gnome-tweak-tool to change icons/themes.

If you are sensitive about your digital data then you must know about Truecrypt(discontinued), a good utility which is no more available and not recommended to use because there are some security issues and won't be fixed. TrueCrypt was initially released as version 1.0 in February 2004, based on E4M (Encryption for the Masses). Several versions and many additional minor releases have been made since then, with the most current version being 7.1a, released 7th of February 2012. On 28th of May 2014, the TrueCrypt official website, began redirecting visitors to truecrypt.sourceforge.net and telling users to use BitLocker.
After end of life of Truecrypt, we see many forks of Truecrypt came as alternatives. Veracrypt is one of them and seems promising to continue development of the product. All issues have been addressed in Veracrypt which were found in Truecrypt and many others, since it is in development we see releases of Veracrypt from time to time, the most recent release of Veracrypt was on August 9th, 2015.
VeraCrypt is a free disk encryption software brought to you by IDRIX and based on TrueCrypt 7.1a. VeraCrypt picks up from where TrueCrypt left and it adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt.
This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. VeraCrypt also solves many vulnerabilities and security issues found in TrueCrypt. It can load TrueCrypt volume and it offers the possibility to convert TrueCrypt containers and non-system partitions to VeraCrypt format.

NVIDIA is well-known company all over the world regarding gaming cards. Sometimes it is really difficult to configure manufacturer drivers for NVIDIA cards in Linux, there could be many reasons for this such as kernel upgrade, and so. By default Ubuntu use the open source video driver Nouveau for NVIDIA graphics card. This driver lacks support for 3D acceleration and may not work with the very latest video cards or technologies from NVIDIA. An alternative to Nouveau are the closed source unified NVIDIA drivers, which are developed by NVIDIA. This driver provides excellent 3D acceleration and video card support.

Nvidia Drivers Ubuntu

Release Highlights of 352.30 Drivers for Linux:
  • Added support for the following GPU: GeForce 910M
  • Fixed a bug that caused poor video post-processing performance in VDPAU when operating on a large number of video streams simultaneously.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
  • Fixed a kernel memory leak that occurred when looping hardware - accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
  • Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
  • Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.


The way people respond to computers' operating systems is eerily similar to how people approach ice cream flavors: Most opt for plain vanilla or chocolate, even when pistachio or buttered pecan is there for the taking, simply because they are afraid to be disappointed with a new taste. Windows and Mac OS X are absurdly popular operating systems, commanding more than 98 percent of the market, and yet there is a supremely delicious alternative, Linux, waiting in the wings.
