[kde-freebsd] Screen goes black after logout

[Steven Friedrich]

I'm using kdm on KDE 4.3.4 and FreeBSD 8-Stable.

On my mom's computer, when she logs out, the kdm login screen appears, but 
then the screen goes black. I am able to log in again by blindly entering her 
password again, and then I can shutdown instead of logging out.

Her machine has a Matrox G550.

My laptop, which has an ATI something or other, DOESN'T exhibit this anomaly.

On each machine, the default resolution is 1280 or higher (the laptop is 
1440x900, her machine is 1280x1024).

On each machine I have used KDE System Settings to set the resolution to 
800x600.  She needs that on her machine due to eyesight. She's 76 yrs old and 
far-sighted.

So I believe this anomaly is a bug in the xorg video driver for the Matrox.

I'd like the community to try this on their machines so we can ascertain which 
video drivers suffer this malady.

Her machine was updated to the latest -stable and ports just yesterday.
