This quick tutorial is going to show you how to display or re-hide ‘hidden’ startup applications in Ubuntu 13.10 Saucy Salamander.
There’s a built-in utility in Ubuntu, which allows to add, remove, and edit additional startup applications. By default the system auto-start services are hidden, here’s how to show it in the box.
Before:
no apps in startup applications utility in ubuntu 13.10
After:
show hidden apps in startup applications
To get started, press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run command below:
sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop
Then re-open the utility and you’ll see all ‘hidden’ apps.
If you just want to change some settings and then hide them again, run this command in terminal:
sudo sed -i 's/NoDisplay=false/NoDisplay=true/g' /etc/xdg/autostart/*.desktop
The latest Nvidia Driver for Linux 331.20 has been released today with lots of changes. Here are new features and how to install it in Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.04 and Linux Mint.
What’s New in Nvidia Linux 331.20:
This Long Lived Branch version 331.20 brings following changes:
Added support for NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL). This library provides a high performance, low latency interface to capture and optionally encode the composited framebuffer of an X screen. NvFBC and NvIFR are private APIs that are only available to approved partners for use in remote graphics scenarios. Please contact NVIDIA at GRIDteam@nvidia.com for more information.
Fixed a bug that prevented configuration files containing application profiles from being loaded when directories were present in the application profile configuration search path.
Deferred initialization of libselinux in the NVIDIA OpenGL driver, in order to avoid a problem where libselinux might not be ready when the NVIDIA libGL shared library is first loaded.
Fixed a bug that could lead to memory exhaustion in OpenGL applications running on 32-bit systems.
Added nvidia-uvm.ko, the NVIDIA Unified Memory kernel module, to the NVIDIA Linux driver package. This kernel module provides support for the new Unified Memory feature in an upcoming CUDA release.
Fixed a bug that caused the X server to fail to initialize when DisplayPort 1.2 monitors were assigned to separate X screens on the same GPU.
Fixed a bug that could cause a deadlock when forking from OpenGL programs which use some malloc implementations, such as TCMalloc.
Fixed a bug that prevented Warp & Blend settings from being retained across display configuration changes.
Fixed a bug that prevented some settings changes made via the nvidia-settings command line interface from being reflected in the nvidia-settings graphical user interface.
Fixed a bug in MetaMode tracking that could cause spurious error messages to be printed when attempting to add or delete Metamodes via NV-CONTROL.
Fixed a bug that caused the NVIDIA X driver to attempt to load the X11 “shadow” module unconditionally, even in situations where the driver had no need to use the module. This could result in the printing of spurious error messages, on X servers where the module was not present.
Fixed a bug that prevented display configuration changes made with xvidtune(1) from working correctly.
Fixed a bug that occasionally caused display corruption in GLX applications while changing the display configuration.
Fixed a bug that prevented glReadPixels from working correctly when reading from Pixel Buffer Objects over indirect rendering, when the image width is not a multiple of 4.
Added a new NV-CONTROL attribute, NV_CTRL_BACKLIGHT_BRIGHTNESS, for controlling backlight brightness.
Fixed a bug that prevented nvidia-settings from creating display device configuration pages for newly connected DisplayPort 1.2 Multi Stream Transport downstream devices.
Added GPU utilization reporting to the nvidia-settings control panel.
Fixed a bug in the nvidia-settings control panel that prevented users from configuring stereo, when stereo was not already configured.
Added support for reporting the tachometer-measured fan speed on capable graphics boards via nvidia-settings and the NV-CONTROL API. The preexisting mechanism for reporting fan speed reports the speed of the fan as programmed by the driver.
For example, `nvidia-settings –query=[fan:0]/GPUCurrentFanSpeedRPM`.
Fixed a regression that caused GPUs that do not support graphics to not appear in nvidia-settings.
Fixed a bug that caused DisplayPort 1.2 multi-stream devices to stop working if they were unplugged and plugged back in while they were active in the current MetaMode.
Added support for multiple NVIDIA kernel modules. This feature allows users to assign different GPUs in the system to different NVIDIA kernel modules, potentially reducing the software overhead of coordinating access to multiple GPUs.
Added support for the EGL API on 32-bit platforms. Currently, the supported client APIs are OpenGL ES 1.1, 2.0 and 3.0, and the only supported window system backend is X11.
Add a new option, AllowEmptyInitialConfiguration, which allows the X server to start even if no connected display devices are detected at startup. This option can be enabled by running “sudo nvidia-xconfig –allow-empty-initial-configuration”
This option is useful in RandR 1.4 display offload configurations where no display devices are connected to the NVIDIA GPU when the X server is started, but might be connected later.
Updated nvidia-installer to provide a scrollable text area for displaying messages from the /usr/lib/nvidia/alternate-install-present and /usr/lib/nvidia/alternate-install-available distro hook files. This allows for longer messages to be provided in these files.
Updated nvidia-installer to avoid recursing into the per-kernel “build” and “source” directories when searching for conflicting kernel modules in /lib/modules.
Added a system memory cache to improve the performance of certain X rendering operations that use software rendering fallbacks. The X configuration option “SoftwareRenderCacheSize” may be used to configure the size of the cache.
Removed the “DynamicTwinView” X configuration option: dynamic reconfiguration of displays is always possible, and can no longer be disabled.
Fixed a bug that caused nvidia-settings to display incorrect information in its display configuration page when all displays on an X screen were turned off.
Updated nvidia-installer to only install the libraries libvdpau and libvdpau_trace if an existing installation of libvdpau is not detected on the system. This behavior can be overridden with the –install-vdpau-wrapper and –no-install-vdpau-wrapper options.
Future NVIDIA Linux installer packages will no longer include copies of libvdpau or libvdpau_trace: VDPAU users are recommended to install these libraries via other means, e.g. from packages provided by their distributors, or by building them from the sources available at: http://people.freedesktop.org/~aplattner/vdpau/

Linus Torvalds finally announced Linux Kernel 3.12. Here’re the new features and how to install / upgrade to Kernel 3.12 in Ubuntu 13.10, Ubuntu 12.04, Ubuntu 12.10 and Linux Mint.
I was vacillating whether to do an rc8 or just cut the final 3.12, but
since the biggest reason to *not* do a final release was not so much
the state of the code, as simply the fact that I’ll be traveling with
very bad internet connection next week, I didn’t really want to delay
the release. Sure, we had a number of driver reverts, and there was an
annoying auto-NUMA memory corruption fix series, but none of it was
really worth delaying 3.12 for.
But the fact that I’m going to be (effectively) off-line next week
means that I’m *not* opening the merge window for 3.13 yet …
…
What’s New in Linux Kernel 3.12:
The Radeon open-source kernel graphics driver has improved Dynamic Power Management, but it won’t be until Linux 3.13 where Radeon DPM is enabled by default along with HDMI audio.
A brand new DRM/KMS driver in the form of the Snapdragon MSM driver written by Rob Clark to go along with his reverse-engineered Freedreno driver for Qualcomm Snapdragon/Adreno graphics.
Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
Experimental DRM render nodes support done by David Herrmann over the summer.
AMD Berlin APU support as the first APU built upon AMD’s Heterogeneous System Architecture (HSA).
The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
zRAM has been promoted out of the staging area of the kernel. ZRAM supports a compressed block device in RAM to avoid paging to disk and is mostly of benefit for systems with limited amounts of system memory.
Various staging driver updates and sound driver work and other glorious work.
