How To Hiberante Ubuntu? | Enable/Disable Hibernation | Show Hibernate Option In Power Menu

Ubuntu Hibernate Main
Short Bytes: In the Ubuntu Linux distro, the hibernation feature is disabled by default since the release of Ubuntu 12.04 on the machines which are not certified for Ubuntu. But the hibernation option is not gone forever. You can enable or disable the hibernation feature in Ubuntu 16.04 and its derivatives using the command line and text editors. It will also show up in the power menu.
Later versions, since 12.04, of the Ubuntu Linux distribution have the hibernation option disabled by default. One of the reasons is the lack of compatibility between Ubuntu and the computer hardware which is mostly dominated by Microsoft Windows. In fact, Windows itself doesn’t enable the hibernation option by default.
The process of hibernation in the case of Ubuntu involves copying what’s stored in the RAM and writing it to the swap partition before powering off the machine. This helps it retain the system state after it’s turned on. But it has been observed that hibernation option doesn’t work well. When the device is powered on, sometimes, all the open files and folders get lost. This has been a cause of my frustration many times. Similar is the case of the Suspend option.

How to Hibernate Ubuntu 16.04?

Ubuntu Hibernation show
For all the needs, the command line is the ultimate destination. You can enable hibernation in Ubuntu by typing the following command in the terminal:
sudo pm-hibernate
Note: Save your work before running this command.
Your machine will turn off automatically after the command execution finishes. Restarting the machine would bring you to the same state where you left, i.e. all the applications and files would be as it is. If this happens then the hibernation process has done its job. If not, your machine would look as if you’ve restarted it with all the open applications gone.
In case, your computer is taking excess time to hibernate, you need to interrupt the hibernation process and turn it off manually using the power button.
Now, the thing is that you would have to type the command every time you want to hibernate your Ubuntu system. However, there is a way to enable to hibernation option forever and also show it the power menu.

How to enable hibernation in Ubuntu 16.04 permanently?

To make the Ubuntu hibernation process permanent, you need to create a new file using a text editor on the command line:
sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
The system requires root privileges to enable the hibernation option, hence, the command sudo should be added. You can use other text editors like vi, gedit, emacs, etc.
Now, copy and paste the following text to file (use the mouse, keyboard shortcuts won’t work):
[Re-enable hibernate by default in upower] Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
[Re-enable hibernate by default in logind] Identity=unix-user:*
Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
ResultActive=yes
Press CTRL+O to save and CTRL+X to exit the nano editor.
Ubuntu Hibernation Enable
Now, logout of your system and then login again, you’ll start seeing a hibernate option along with the Shut Down and Suspend options.

Experience the Front Row in In Current VR technology most commonly uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. The Virtual Reality Modelling Language (VRML), first introduced in 1994, was intended for the development of "virtual worlds" without dependency on headsets. The Web3D consortium was subsequently founded in 1997 for the development of industry standards for we

Intel Ice Lake-U mobile processor to have 10nm architecture and improved graphics

-
It hasn’t even been a year since Intel’s Coffee Lake architecture was released and we are already hearing news about the upcoming architecture. It is speculated that Canon Lake would likely be the next architecture range from the company, however a new leak has revealed information about Ice Lake. This new upcoming range, unlike Canon Lake, would fall under the 9th-generation of Intel processors. According to the leak , the Intel Ice Lake-U processor is expected to feature new core and graphics uArch. The unnamed chip comes with UHD (4K resolution) Gen11 LP integrated graphics processor, has 48 execution units, 768kB of L2 cache 6GB of shared system memory and base frequency of 600MHz. This is a healthy jump and while the boost clock is still unknown, there is the mention of DDR4 SODIMM memory. The current generation has 512kB of L2 cache, and a base clock speed of 300Mhz. Reports suggest that Intel has managed to achieve this boost thanks to the adoption of 10nm

Intel Ice Lake-U iGPU May Feature 48 EUs

-
Intel Ice Lake iGPU Leaked Over the past couple of years, CPU performance has largely stagnated. Instead, the new area of focus is the iGPU. Graphics are increasingly important to users as graphical demands increase. Nowhere is the need for improved graphics more poignant than for mobile laptops. To meet this new demand, Intel is reportedly working on improved iGPUs for Ice Lake CPUs. The new iGPUs will feature up to 48 EUs for the U-series of chips. The information from a SiSoft Sandra online database entry for a new prototype Ice Lake chip. The new iGPU is a UHD graphics with Gen 11 graphics. That should a major architecture upgrade over the current Gen 9.5 graphics in Kaby Lake and Coffee Lake. Due to the new architecture, performance should see a good bump. The bigger improvement should come in the increased number of execution units. The count jumps up from the 24 EUs in current U-series chips to a total of 48 EUs for Ice Lake U. Ice Lake iGPU Features Double
