Today, I must admit that things have seriously changed and distributions like Ubuntu are real gems of OS.
I coded some small programs many many years ago (1996… ouch!) when the text mode was the default interface and you had to type startx or something like this to launch a graphical interface that often didn’t start because the graphics card was not supported or because of another mysterious error. To be honest, I’m a total newbie with Linux. Three days ago I installed the latest version of Ubuntu (10.10 RC) on a dedicated PC (Core 2 Duo E8400 + GeForce GTX 260) to test it. UPDATE: FurMark is now available under Linux: GpuTest – Cross-platform GPU stress test and OpenGL benchmark.
