I play a game called Quake Live (Browser Based fps).
I tried getting it to work in Chrome (Linux version) but it shows as grey screen.
I downloaded the Quakelive plugin for Linux and tried the dedicated browser called QLPrism. The game worked but the graphics did not. This may stem from the video drivers not being installed, in which case I could use some help on that. I have NVIDIA GeForce GT 520.
I tried this a while ago with Unreal Tournament and had a similar graphic issue (used Wine for that)
Are games like that common on Linux/Ubuntu?
