View Full Version : 1.0-9746, Sun Ultra20, Quadro FX1500 8-bit overlay problem

01-23-07, 01:08 PM
We have an Ultra20 with dual Acer 1680x1050 monitors. When an 8 bit overlay window is moved to the second monitor, the contents of the window is shifted to the right about 1/8 inch, so that it extends outside the right edge of the window. This is with a gui type window. With a 8 bit window displaying graphics, the contents of the window appears shifted the same, but in addition, when displaying a graph over top of a seismic data display - the points on the graph, displayed using X's, do not line up with the graph line. We have had to revert to 1.0-8776 to get rid of this problem. Unfortunately 8776 has a different problem with 8 bit overlay mode; it regularly causes the desktop to freeze up, requiring Xorg to be restarted.

Which application is required to reproduce this problem?

It's seismic data processing software called "Focus" made by Paradigm (www.paradigmgeo.com). I doubt that helps much. It's the only program we use that needs the 8 bit mode.

I've managed to find a remedy for this problem. None of the newer drivers are a fix.

The problem goes away as long as the following option line is added to the xorg.conf:

Option "TwinViewOrientation" "LeftOf"

Older drivers do not exhibit this behavoir.
