Regarding the "Can't get resolution higher than 1280x1024" thread...I can only speak about my case and probably the OT's. The problem is two-fold. First, the monitor has a bug which causes delivery of incorrect EDID information to X when probed. It manifests itself when the connection is digital and the OS is 64-bit. Analog connection to the same monitor does not seem to suffer from this problem in either 64-bit or 32-bit. A possible workaround is to have X ignore the EDID data and manually set up the parameters in xorg.conf. I was not able to get this option to work. That is the second problem. Whether this is a bug in Xorg or in the nv driver (that I use), I have no idea. There was a thread relating to the EDID issue (unable to ignore) in the LKML in February. Akemi
