Laptop graphics chipsets
I'm shopping for a new laptop, and considering the Inspiron 4100 or 8100 with UXGA screen. I'll be running Linux on it.
Among current Dell offerings (ATI Mobility Radeon, NVidia GeForce2 Go, ATI Mobility Radeon 7500), what's best supported under Linux? My concerns (in order of importance) are stability, correctness, performance, ability to run a separate X display on an external display, and avoiding closed-source software.
Another question: How much am I going to notice performance differences between different cards, given that I'm not a gamer? My current laptop is sluggish when viewing and editing digital photos, running VMware, or scrolling in complex PDFs; I'm not sure whether boosting the graphics in a new laptop will make me happier, or whether these tasks are CPU-bound and the CPU is all that'll really make a difference.
