Ooops, sorry. I left out the W - I am using a Samsung 940BW, whose
native resolution is 1440x900.
I tried ps3videomode from both root and non-root. I don't know of
any way a command would not even be found by non-root users. At the
worst, one might get a message saying that one needs to have
privileges to run it. I then tried a "locate" and "updatedb", finding
that these useful commands were missing.
I have been using kboot.conf to change resolutions. It is very time
consuming. In my investigations, I was hoping to write a script which
tries a mode for about 30 seconds and then switches back to a default
mode to avoid getting stuck in a non-functional video mode (that
happened last night and I needed to shut off the machine using the
switch.)
Thanks for the suggestion of adding 128 to the mode number - I'll
play with that.

Did you try switching to 'root' before running ps3videomode? I'm
pretty sure non-root users can't run it.
If you're using a Samsung 940b, you're native resolution is
actually 1280 x 1024 ( http://www.samsung.com/Products/Monitor/
LCD_Digital/LS19HABKBXAA.asp).
Also, if you add 128 to whatever mode you want to run in, you can
get the true resoultion expected. Normally, the PS3 compensates
for the overscan on Televisions that would make the edges of the
video be 'off screen'.
I run in 1080p mode with ps3video 131 (mode 3 + 128 for non-
overscan mode).
Try ps3videomode 140 on that 940B (1280 × 1024 with non-overscan
mode.)
Also, running ps3videomode from the enlightenment desktop would
screw up the video pretty badly for me. So try changing the
kboot.conf file to offer different ps3video options.

I have done some investigation of the various video modes on the PS3
(in Linux) and find that one is not very badly compromised when using
a standard computer monitor.
First, there are at least 3 VESA modes which are the same as standard
computer modes (at 60 Hz):
Mode 11 - 1280x768
Mode 12 - 1280x1024
Mode 13 - 1920x1200
I am considering trying numbers >13 to see what happens. After all,
the RSX is a modified NVIDIA GPU and they probably support lots of
modes in addition to the published ones. All I need is a working
"ps3videomode" command - it was not installed with the standard YDL5
installation (nor was "emacs", "locate" and a host of other nice
commands - does anyone know an easy way to get them all without
installing the RPMs individually?)
These three modes work on my Samsung 940B (using the digital port)
whose native resolution is 1440x900. I was blown away that the
1920x1200 worked, though the monitor put up a little message
complaining about it. Of course, they were all scaled and looked more
or less fuzzy (actually the 1920x1200 was best, but I got a headache
from the fuzziness using it for any time). I believe that using a DVI-
VGA adaptor should allow the monitor to avoid scaling at the expense
of a small dark border (on modes 11 and 12).
By the way, the Samsung monitor is HDCP compliant, but I find it hard
to believe that this matters for anything except (possibly) playing a
BlueRay movie. I am pretty sure it doesn't matter in Linux.
The bottom line is that one can get good video using a fairly cheap
1280x1024 LCD monitor (I have seen them for $150 or less). Video
acceleration is another matter...
