Hello,
I have some problems and questions running a linux SMP kernel and X. I built a SMP
kernel from linux2.2.6 without any problems. Everything boots fine, but X acts funny.
The window manager (does not matter which one, afterstep, fvwm, olwm, etc.) does not
track the window focus. I move the mouse and the focus does not change to the new
window. I even single click on the title bar and the window still does not get the
focus.
If I build a 2.2.6 kernel without SMP the windowing system works fine. Argg. Me
thinks it has to do with interrupts.
I'm running an older INTEL system that uses dual Pentium 166 Mhz processors. It
supports Intel MultiProcessor Specification v1.4 . Below is the boot info from dmesg
and the info from "cat /proc/cpuinfo" .
Has anyone ever had this problem?
Cheers,
Curt
