I'm using a Dell Latitute D620, running Windows XP Professional 32x, using the Mobile Intel(R) 945GM Express Chipset Family. I've updated my drivers, updated my Java, Followed your guide and the guide located here:
ok try this:go to control panel. go to display. click settings. go to advanced. click troubleshooting. move it to the third lowest setting. done!
My work laptop is a Dell Latitude D820 with a 945GM card, and I got the Open GL error when trying to run Minecraft. The driver suggestion by the OP did not work, but the suggestion to change the slider in troubleshooting did work.
