GPU issues
I had a thread earlier about this, but this is becoming an everso evolving issue for me. I've got a setup that uses an Intel HD Graphics 4000 paired with a Nvidia GeForce GT 640M and I am having issues getting either to work with Ubuntu (installed with wubi). This is what I have tried:
-Updating just the Nvidia driver. Rebooted and gave me a black screen I could not fix. Was using 12.10 on this attempt.
-Updating using Bumblebee and primus. I tried it on 12.04 and it gave me a black screen. I tried it on 12.10 and it got through, however it told me it could not access my secondary GPU. Primus was also giving some fatal errors saying it could not contact Bumblebee. Weirdly enough, using primusrun firefox was able to boot no problem.
-Updating just the intel driver. I followed the steps provided on Steam Support and updated the files. Installation finished fine but rebooting led me to a black screen that I could not fix.

So right now I am led to believe there is some mass incompatibility with the setup causing it to stop functioning. With that last attempt not working, I am running out of options. Any solutions to this predicament? Would perhaps switching to a proper install of Ubuntu fix any of this?

If they are two seperated GPUs, I guess you can only use one of them. at least that is what i have read so far. So try using only the nvidia driver.... if it is hybrid i have no clue why it isnt working.

Does 'optirun' works? It might give you more information about the error. You can enable more debugging information by calling 'optirun -vv'. Anyway, I think it will be better to google answer or ask on bumblebee forum because it is not actually a Steam issue.

It uses Optimus, so one is integrated while the other is dedicated. I tried just going for the 640M Linux driver in the past (was also my first attempt) and it gave a black screen upon reboot.

I believe optirun was the one that told me it could not access the secondary GPU. I'll try posting this on the Bumblebee forum and see where it takes me. I tried askubuntu, but I didn't get a reply.
