I'm using Ubuntu 8.04 and after trying stepmania and zsnes to use 1024x768 they either get buggy and end up getting sandwiched between the panels or even freeze the system. My graphics card is an NVIDIA GeForce 6100 nForce 405. However, whenever I reboot, Ubuntu seems unable to recognize the card but if I reinstall the driver, everything seems to go back to normal. Does anyone know of a fix for this?
