Nvidia 340.24 Add Support For G-SYNC Monitors

Last updated: July 12, 2014

Nvidia has just announced the release of driver 340.24 for Linux with numerous improvements and fixes. One of the exciting news is the initial support for G-SYNC monitors.

Nvidia 340.24 was released on July 8th, 2014 with following changes:

Fixed a bug that prevented 3D Vision stereo and ultra low motion blur modes from working on G-SYNC capable monitors in some cases.

Fixed a bug that caused the “Allow G-SYNC” checkbox to be displayed in nvidia-settings even if the GPUs in the system are not capable of G-SYNC.

Fixed a kernel crash when running some applications with IOMMU functionality enabled.

Fixed a floating point exception in the OpenGL driver when running “Risk of Rain” under Wine.

Made various improvements and corrections to the information reported to GL applications via the KHR_debug and ARB_debug_output extensions.

Fixed a bug that caused GLX applications which simultaneously create drawables on multiple X servers to crash when swapping buffers.

Updated nvidia-settings to report all valid names for each target when querying target types, e.g. `nvidia-settings -q gpus`.

Added support for controlling the availability of Fast Approximate Antialiasing (FXAA) on a per-application basis via the new __GL_ALLOW_FXAA_USAGE environment variable and the corresponding GLAllowFXAAUsage application profile key. See the README for details.

Fixed a bug where indirect rendering could become corrupted on system configurations that disallow writing to executable memory.

Updated the nvidia-settings Makefiles to allow nvidia-settings to be dynamically linked against the host system’s libjansson. This option can be enabled by setting the NV_USE_BUNDLED_LIBJANSSON Makefile variable to 0.Please note that nvidia-settings requires libjansson version 2.2 or later.

Removed the runlevel check from nvidia-installer: the installation problems formerly associated with runlevel 1 no longer apply.

Added initial support for G-SYNC monitors.Additional details and system requirements can be found at:http://www.geforce.com/hardware/technology/g-sync

Improved support for running the NVIDIA driver in configurations where writing to executable memory is disallowed.Driver optimizations that require writing to executable memory can be forcefully disabled using the new __GL_WRITE_TEXT_SECTION environment variable.See the README for more details.

Fixed an X driver bug that caused gamma ramp updates of the green channel at depth 15, on some recent GPUs, to be ignored.

Fixed a regression, introduced in the 340.17 public beta release, that caused the NVIDIA X driver to access freed memory when exiting a GLX application that used either of the GLX_NV_video_out or GLX_NV_present_video extensions.

Install Nvidia 340.24 in Ubuntu:

IMPORTANT NOTE: If you’re just looking for a working drive for your Nvidia card in Ubuntu Linux, please search for and install nvidia-current in Ubuntu Software Center.

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, do:

1. Remove the previous installed proprietary driver and install the latest updates-dev package. Then restart your computer

sudo apt-get purge nvidia*; sudo apt-get install nvidia-331-updates-dev

2. Download the driver:

32 bit Linux | 64 bit Linux | 32 bit ARM

Check the release note for the supported GPUs.

3. Press Ctrl+Alt+F1 (~ F6) to switch to command console and log in.

4. Stop the graphic session by running:

sudo service lightdm stop

Replace lightdm with gdm or mdm if you’re using Gnome display manager or Linux Mint.

5. Now give executable permission and run the downloaded package:

chmod +x ~/Downloads/NVIDIA-Linux-*-340.24.run && sudo sh ~/Downloads/NVIDIA-Linux-*-340.24.run

Follow the onscreen prompt and you’re done.

(Optional) If for some reason the new driver does not work properly, remove it via:

sudo sh ~/Downloads/NVIDIA-Linux-*-340.24.run --uninstall

For easier way, wait the driver to be built into xorg edger PPA. By then, you can install it via 3 commands:

sudo add-apt-repository ppa:xorg-edgers/ppa

sudo apt-get update

sudo apt-get install nvidia-340

Try Evolve OS Budgie Desktop in Ubuntu 14.04

Last updated: July 8, 2014

Budgie is a lightweight GTK3 desktop session using libmutter and a bottom panel. It’s the default DE for Evolve OS, a new desktop Linux distribution.

Budgie desktop has a single panel budgie-panel which uses trivial amounts of RAM (in the region of 7MB) when started. However, when you first open the menu, GTK actually loads the images. This needs to be hacked a bit, as it delays the first open, and should be done in an asynchronous manner.

Budgie’s window manager is currently based on libmutter, so naturally with 3.12 will gain support to be a Wayland compositor.

Budgie Desktop integrates with the GNOME stack, and as such requires certain components to operate correctly. Your distribution should provide an autostart file for gnome-settings-daemon in its package.

budgie-session will attempt to parse the file and launch it if it is found, which is guessed to be living in: /etc/xdg/autostart/gnome-settings-daemon.desktop

If budgie-session cannot locate the file, gnome-settings-daemon will not be launched, and dynamic settings for themes, etc, will not work until it is launched.

Ubuntu users: It is highly likely your theme or Ubuntu setup can affect the usability of budgie-panel.

If you have focus/use issues with the panel (i.e. not taking input), disable overlay scrollbars by running below command in a terminal window:

gsettings set com.canonical.desktop.interface scrollbar-mode normal

Install Budgie Desktop:

NOTE: Budgie is still in early development stage. It has a lot of to-do things, only install it on test machine before it gets table!

To install it (from a third-party PPA), press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run commands below one by one:

sudo add-apt-repository ppa:sukso96100/budgie-desktop

sudo apt-get update

sudo apt-get install budgie-desktop

If you like Budgie Desktop, please contribute or report to: github.com/evolve-os/budgie-desktop

sudo add-apt-repository "deb http://www.bunkus.org/ubuntu/trusty/ ./"

wget -O - http://www.bunkus.org/gpg-pub-moritzbunkus.txt | sudo apt-key add -

sudo apt-get update

sudo apt-get install mkvtoolnix mkvtoolnix-gui

After that, running regular Ubuntu updates (via Software Updater) will upgrade the app if there’s a new release.

2. Hate Linux commands? Well here is a step by step guide in graphical

1.) Open Unity Dash, search for and open Software & Updates

2.) Under “Other Software” tab, click Add button and then paste below line and click the Add Source button.

deb http://www.bunkus.org/ubuntu/ trusty main
