How to upgrade OpenGL?

Hi, I am using precise 5.7.1 - and since last posting questions I have been happily learning and playing around with linux and linux puppy using the live CDs which forgive my many errors! (one of the reasons I love using puppy
At the moment I'm wondering - can we upgrade the version of OpenGL by using the ppm or 'manually' or something else? I have a game that tells me I need 'at least' OpenGL 2.0 - and the version I have is 1.4 (1.4 Mesa 8.04 is the string that returns when i ask for the glxinfo in terminal).
Thank you for any input.
ps - thank you to everyone who helped me over the years - I tend not to post back once I'm off and learning from what's been said - I'll try and make a resolution to change that - the help has been appreciated!

You got it a bit wrong (blame glxinfo devs

)
glx stopped at 1.4 and is used only for indirect rendering.
What you should look at are :
OpenGL version string: 2.1 Mesa 8.0.4
OpenGL shading language version string: 1.20
on the machine I post now. Version and shading version are directly related.
If you know you installed the best driver for your card (sorry but you are a bit cheap on info) install driconf and after that modify .drirc file to match your videocard capabilityes
In general OpenGL and DirectX versions are printed on the backcover of your videocard and in manual..
Thanks for the clarification

Hi, yes, sorry, I was 'cheap' with the info - I'm not to clear how much I have to give about any question since I'm not sure what connects with what - but I realize more info is better!
Good to know glx stopped at 1.4 -
Though when I figured out what video card I had in this old ThinkCentre -
Intel Corporation 82915G/GV/910GL
it turns out that only supports up to 1.4 openGl anyway
Still knowing this explains why when I bypass the selection for intel video and just press cancel on start up that nothing really changes in the puppy experience. And also why my other computer with a better card can run the games I'm wanting to play.
Sigh - I was avoiding repairing the other computer since I have to buy a power supply but I suppose I'll just have to get to it!
Thank you for the input - and I will try to remember more info is better!

82915G is really dated. I read that the linux driver for this was not updated in years.
If you need to still use that machine i would reccomend buying an mid-range to top-range ATI or nVidia graphics card from 2005-2008 era from an discarded depot or something like that. Any newer will start revealing severe CPU bottlenecks.
I don't use intel graphics at all (or disable it on BIOS if one accidentally exist) so, from here on, maybe someone more versed with intel IGP would help you.
Edit : Since puppy precise is based on Ubuntu precise you can search ubuntu forum for advices/solutions related to your chipset.
