I've had the pleasure to be working much closer with linux in the last few months and have decided in the spirit of advancing my tired old brain to run a couple of Ubuntu Linux Gnome machines for testing (and breaking) purposes.
An interesting thing I came across today was that one of the machines has something called nVidia optimus hardware, which means simply put that the "normal" 2D graphics are processed by the inbuilt Intel graphics chips whilst the intensive 3D stuff such as gaming or CAD is handed off to a nVidia graphics processor. How interesting. (Who remembers 3DFx VooDoo cards?...)
This is not current officially supported natively in Ubuntu 13.04 at this point and loading a vanilla setup will not give you full advantage of the nVidia card BUT as always with the linux community someone has done something about it. Enter Bumblebee.
So here is what I did:
1. Fresh install of Ubuntu Gnome 13.04
2. Now you'll have to add the repo's for bumblebee.
a. $ sudo apt-get-repository ppa:bumblebee/stable
b. $ sudo apt-get update
c. $ sudo apt-get install bumblebee virtualgl linux-headers-generic
3. add your user to the bumblebee group with
a. $sudo usermod -a -G bumblebee $USER
Now to run a program through the 3D graphics card just type 'optirun <app name>'
a. $ optirun glxspheres
See below a screen shot of the results.
glxspheres running normally reports using the MESA DRI Intel GL renderer and pumps out 67 FPS whereas the second time I've run it with $> optirun glxspheres it users the NVS 4200M as the GL Renderer at 137 FPS - twice the speed.
Well, even though it's over now I think that we've had probably the best summer since I've been living in the UK (7 years now!) Here are some nice wee pics from a day at Crammond with Wee P
What a good Christmas it's been this year , I've had the week off and I'm not back at work until next Wednesday, giving me plenty of time to spend with the kids and the wife. Got a very decent haul of pressies including a Kindle, Lego Star Wars: The Battle for Hoth from the Good Lady and The Hobbit board game and MtG: Dueling pack from some friends and Forza Horizon (xbox) along with the usual teeth-rotting haul of chocolate and cola....
Christmas dinner was at ours this year and we hosted the Mother-in-Law so it was a chilled out day. The Good Lady did a great job on the turkey dinner and we've been eating turkey ever since...
Major pressies for the tin lids this year from Mr S were a Doll's House for Wee P and a Little Tikes slide for the boy - although they spend more time playing with each others gifts I think...
The middle weekend of the Olympics - which has not been off our TV really. Some remarkable scenes tonight with Ennis winning the gold medal for the heptathlon. Big thing have been happening in the Shooter household as well: a few weekends ago was Wee P's 3rd birthday and we had a great little party over at Drum Brae leisure centre where we had free rein over the massive sports hall with a bouncy castle basketball hoops and loads of sports equipment!
Between then and now there has been a few weeks of self imposed hell where we took it upon ourselves to finally bite the bullet and teach Wee P to sleep in her own bed all night, as up to this point she would appear by our sides sometime between 12 am and morning. Well it took a lot of sleepless nights and a lot of tantruming but we've cracked it with the help of some tough love and shameless bribery. I've loosely documented what we did and will write about it separately for those of you interested.
Now we are working on the wee man as we have moved him into the room with Wee P and that's not going too badly either, one thing I've discovered: our bed is frigging HUGE...
Today I took my bike for a ride and broke the pedal right off the crank....that was a fun walk home. Tomorrow we are off to some of the festival activities to the CBC and Cbeebies shows with the kids. Should be fun.
The last couple of months have been really quite busy with a lot of things happening at work and home, I've had two work trips to London and Wee Jack who is now 6 months old is full of the beans and almost on the move!
As usual, I've have stuff up on BigRedBarrel, including a Diablo III review and the Uninteresting Life cartoons and here are the links:
