I have been using FreeBSD since 4.x. I have had a lot of weird issues through the years, but this is one I am not able to resolve. If I enable cups or webmin, I get a small line of random graphics across the top of my screen. The line does not affect the system stability, but it's extremely annoying. It takes up anywhere from 10 to 20 lines of my display, and displays random colors from red, green, blue to purples and yellows. I attempted to post a picture with my last post on this issue, but pictures appear to be forbidden in the list. I did however find a page that seems to document the problem, although the way the problem happens is different from how I trigger it on my system. The URL is here: http://www.freebsd.org/cgi/query-pr.cgi?pr=usb/95348 A quick quote: Unplugging the USB keyboard causes a thin and irregular horizontal stripe appear near the top of the screen (xorg 6.9.0) across almost all its width. Moving the mouse (either USB or PS/2) causes this noise to change shape. The consistency of the system doesn't seem to be affected by this stripe, though. Occasional random characters have been noticed coming from the USB keyboard, like a stuck key, once replugged, but I couldn't repeat it reliably. The noise on the screen is of one uniform colour (red on my desktop, green on my laptop). Looks like someone is spilling data on the frame buffer. This is exactly what I see, but on my system it is not triggered by USB devices. Has anyone else experienced this? Is there a fix? I don't mind not having webmin, but cups is fairly important.
