Sometimes on startup, Ubuntu does not recognize my USB Keyboard & Mouse. This problem is frustrating as Windows seems to recognize them.

It took me a while to recognize the root of the problem was with the USB 3.0 ports on the Motherboard. By moving the usb connections to the USB 2.0 ports on the motherboard this problem was solved.

Problem: USB Keyboard and Mouse dont work on boot up.
Solution: Move the connectors to the devices from a standard USB 3.0 port to standard USB 2.0 port(check with your motherboard manual for specifics)

Using Phone LED As FlashLight: Android

One of the most attractive features of my Galaxy Ace is its LED Flash. This bright light can be used as a torch when needed, unfortunately there is no default app available to make it work.

Whats worse? I could only discover a single app that made this operation possible.  The app goes by the name “Tiny Flashlight + LED” and is available in the Android Market.


The app also provides a handy widget that allows you to turn on the torch right from the home screen


The creators of the app say that it works with these phones:
Samsung Epic 4G Galaxy S II S2 SII GS2 GSII Tab 7.0 8.9 10.1 Ace Cooper Fascinate Moment Acclaim Transform Mesmerize Charge Behold 7500 Moment, LG G-Slate Ally Apex GW620 KH5200 EVE Shine Plus Optimus 2x G2x Speed, Motorola XOOM Atrix 4G Droid Bionic X 2 i1 Pro R2D2 Backflip Cliq XT Milestone Defy, Nexus, N1, Sony Ericsson XPERIA X10 X3 Neo Pro Play Arc, HTC Incredible G2 Desire HD HD2 EVO Shift 3D myTouch Slide Wildfire Legend Thunderbolt Inspire Sensation Merge, Bright Flashlight, Dell Streak 2.1, Sharp IS01 JN-DK01 SH-10B Lynx IS03 SBM003SH SBM005SH, Pantech Vega SKY X, Sanyo Zio, Toshiba Regza T-01C, bright flashlight, bright led, Garmin Asus A10, Huawei Ideos X5 U8800, Archos Coby Kyros 7015 LED, Acer Iconia A500.

Fixing the HP Tx1000 series Laptop boot problem…

The HP Tx1000 series laptop has a unique problem with its Nvidia chip. Due to a really poor design wrt to the heat sink to the GPU, the chip reaches very high temperatures during operation causing the system to not boot properly. This problem is apparently very common and occurs within about two years of moderate use.

HP will replace the motherboard if the laptop is in warranty, if not their recommendation is a 400$ replacement of the motherboard. The laptop is awesome bar this problem and that solution is simply ridiculous…

Here is an alternative solution that worked for two of my friends and me. We all had different versions of the tx1000 series laptop and the system is working perfectly now… As an added bonus the system has better heat emission and easily reduces the temperature of the GPU by over 25%
