Gang, I recall a few weeks back hearing about some black listed video cards due to driver problems in X11R4 (and possibly other versions). As I am about to buy a new laptop, I just want to check to see if the one I am planning to purchase will have this problem. I am looking at one of the IBM T20 series laptops with an "S3 Savage IX8" video controller. I will be using X11R3.X (probably) on it. Has anybody had any trouble with this combination, or can anybody suggest whether I am likely to have trouble with it? I am planning to do some serial communications testing with the laptop, so I will need a deterministic response within reason (latencies measured in microseconds not seconds, please). Any experiences others have had or any advice is greatly appreciated.
