How to Install MuPDF 1.8 in Ubuntu:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

sudo apt-get update

sudo apt-get install mupdf mupdf-tools

Method 2 For those who don’t want to add PPA:

Depends on your Ubuntu edition (e.g., 15.10, 15.04, 14.04, and 12.04), and OS type (i386.deb for 32-bit and amd64.deb for 64-bit)

select download the .deb packages for mupdf and mupdf-tools from the link below:

To set default, go to file’s context menu -> Properties -> Open With tab -> select MuPDF from list -> finally click ‘Set as default’ button.

For mouse behavior and key bindings run man mupdf command in terminal.

Nvidia Driver 352.30 Released with Various Fixes [PPA]

Last updated: August 29, 2015

Nvidia announced the 352.30 release of its Linux driver yesterday with GeForce 910M support and various important fixes.

Release highlights of Nvidia 352.30:

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.

Install Nvidia 352.30 from PPA:

For Ubuntu 15.10, Ubuntu 15.04, Ubuntu 14.04 and derivatives (e.g., Linux Mint 17.x, and Elementary OS Freya), the new driver can be easily installed from an PPA repository:

1. To add the PPA, open terminal from the Dash/Launcher/Ctrl+Alt+T. When it opens, run command:

Last updated: July 26, 2015

Ubuntu 14.10 Utopic Unicorn finally reached the end of its life on July 23, 2015. No more package updates will be accepted to 14.10.

Ubuntu 14.10 was released 9 months ago, on October 23, 2014. As a non-LTS release, it has a 9-month month support cycle and, as such, the support reached the end of life on last Thursday. Users of Ubuntu 14.10 may upgrade to Ubuntu 15.04 (ends on January 2016), or install Ubuntu 14.04 LTS which has a 5-year support (until 2019).

To upgrade to Ubuntu 15.04, see:
