[Openchrome-users] openchrome-users Digest, Vol 46, Issue 5

Fri Aug 7 03:22:17 PDT 2009

The non-existent mouse is a bug/feature(I like it) that shows up when the driver is set to output to the CRT device, but the only available display is the DFP. This is actually a rather handy feature for touchscreens, where a mouse pointer just gets in the way. However, if you want to see see it, just put the following under the driver section of your xorg.conf file

Option      "ActiveDevice"    "LCD"

The problem with the distorted display is probably related to bad DDC info for the LCD in question. You could try specifying the exact timings and disabling the DDC check. Add the following to your xorg.conf file in the driver section

Option      "NoDDC"

Now just create a modeline that is appropriate for the LCD with gtf according to the Manufacture specs of the display.
