Hi, I have a big problem with glxgears and my laptop. whenever I start glxgears I get a high pitch tone coming from my laptop screen. If I move the window to the corners the frequency of the tone rises. is this a xfree driver error or is my gpu or my display broken? I'm using Xfree 4.3.99 snapshot 13 on a linux 2.6.0-test7 kernel. I tried different AGP modes (1,2,4) but the behaviour is still the same. playing games like tuxracer doesn't show this problem. andreas _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
