Using Crossover, LoG installs perfectly, but then throws a D3D error, I guess because the driver for Intel card doesn't support many things. But all is not lost ! Download Swiftshader from Transgaming, replace ~/.cxoffice/Grimrock/drive_c/windows/system32/d3d9.dll with the d3d9.dll from swiftshader, and launch LoG: it WORKS !
EDIT: I forgot, you need to go to Wine Configuration panel and force d3d9 to Native rather than built-in.
Well, if you're like me and have a relatively low-powered i5 laptop, it works but it's too slow to be playable. If you're happy enough to have a beefier machine, you might get better results.
Oh well, was worth a try
