Solve video tearing on Intel + Ubuntu (Unity and GNOME Shell)

Video tearing has been the bane of Linux’s existence on desktops and laptops, but the situation is vastly better than what it was a year ago. This post is related to fixing issues with the Intel HD3000 and HD4000 (Sandy Bridge and Ivy Bridge) series of graphics cards in Ubuntu. This is a clean fix that doesn’t involve any PPAs or experimental drivers, and has been tested on my HP Pavilion G4 running Ubuntu 12.04 on an Ivy Bridge i5. Continue reading

Installing CUDA 5 on Ubuntu 12.04

This is a follow up to my previous post which was aimed at CUDA 4.2 on Ubuntu 12.04.

I could have used the included setup CD, but that’s not how we roll! Today, I’m going to detail a few steps to get your DSL-2750U working via the web interface. Albeit a little daunting at first, the web interface is actually quite flexible once you get the hang of it. A lot of these steps are probably recyclable for other routers, more so for other D-Link products that use a similar interface. Continue reading
