I just installed Ubuntu on my Intel Latitude D620 and put WINE on it so that I could run some of my games that I had when it ran XP. The problem is, most of the games have major problems with the graphics; primarily, the 3D ones. I have yet to find any drivers with which I've had any amount of success (I've tried mesa, xc, and a couple others, none of which I've managed to compile, or even configure.)

Can anyone help me work this out?

(Note: Other people have reported perfect success with these same games, so I know it's not WINE.)

The driver for your card should be installed by default in Ubuntu, as you can verify with:

I recommend a dual boot with Windows for your gaming needs. If you tell us the name of the games, maybe someone can help you... (not me though, I am not a Windows gamer)

That's odd, considering when I go to System Settings < Detail < Graphics it says "Driver: Unknown".

Also, Civ4 and Operation Genesis. Both of which aren't major games and many people have gotten to work with WINE. But, they are also the only two which use 3D graphics to a large extent.

If there are errors they'd show up in /var/log/Xorg.0.log I believe.
But I'd be surprised if there were since the Intel 945GM is a *very* common piece of hardware well-supported by all Linux distros.

Try this terminal command:

I see 'i915' next to video, indicating the Intel 915 driver is loaded and in use for my Intel Corporation Mobile 945GM/GMS card.

Please post the output of

lsmod | grep video:
glxinfo | grep render
/var/log/Xorg.0.log:
There was quite a bit in there. One i did see a lot was:
The the 2D graphics work exelently, the problem is when I try and do anything with 3D.

Install mesa-utils, like suggested with and try again.

Also, I tried running it again with that, still could load the 3D.

The output of glxinfo shows that your card is working and should deliver 3D acceleration. Can you run native 3D applications?

Such as what?

Maybe try Tuxracer.

Couldn't find it, but I'm also looking into WINE DLLs now.

Sorry, they changed their name to Extreme Tuxracer, the package name is extremetuxracer.

There are several WINE registry tweaks you can do to try and squeeze some extra power out of WINE and Windows based applications, but it won't be much:

I've had very little luck telling the difference between using these options and not using them. For some Windows applications, it's just best to knuckle under and dual-boot.
