I've been using xrandr -o right for portrait viewing and not had a
problem with it with the previous release (Lucid Lynx)

4)

After upgrading to 11.4, sometimes xrandr -o right works perfectly,
intermittently it rotates the screen contents, but the display is
distorted with the content appearing twice (one copy above the other) in
the top and bottom half of the display.  And there seems to be a kind of
"venetian blind" effect too, with display line being alternately plain
gray and containing the displayed content.

Mercifully xrandr -o normal always (fingers crossed) returns the display
to normal, though I notice all programs appear to have been collapsed
into workspace 1 (of 4).
