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.
