The skinny is this, if I run any of the following programs, I can't
interact Linux from that point on:
My system is:
Base RedHat 5.2 system, Upgraded to 2.2.5-2 Kernel successfully. Added
Gnome1.08 stuff from packages put together under Redhat 5.2 files on
www.gnome.org. Built my own custom kernel to do all the APM stuff. Added
a /etc/rc.d/init.d/gdm file to start the gnome "xdm" like program.
Pentium II 300 Mhz
This system was stable and working Great. I was using enlightenment /w
additional themes. AND THEN...
As the machine was booting up, my son (2 years old) wiggled his new
HotWheels mouse (a serial mouse which I had forgotten was plugged into
cua0, the modem's port). I didn't see him move it, I noticed the reverse
video character move on the screen in the brief instant between when gpm
is loaded and gdm takes over.
I thought "Oh great!" because I remembered something about gpm
automatically recognizing serial mice. I figured that I might have do
"deconfigure" something because my modem uses cua0. But when gdm came
up, There was a surprise awaiting me. Linux now refused to take
ANY input from either the keyboard, nor the mouse. I was forced to turn
the power off via the switch on the back of my computer, because the
normal button was putting my Linux to sleep and waking it back up (APM
was working at least).
I expected it to work upon reboot, because I had unplugged the Hotwheels
Mouse. I was wrong. Reboot, fsck a 2Gb and a 1Gb partition. This time
up in single user mode. Thankfully it worked.
I have no earthly idea why, but any program that attempts to even read
/dev/psaux prevents ALL keyboard I/O. I have checked the device file and
it is Major Number 10 Minor Number 1, with permissions as follows:
crw-rw-r-- 1 root root 10, 1 Apr 29 15:13 psaux
lrwxrwxrwx 1 root root 5 Jan 26 1998 mouse -> psaux
I am hoping that someone out there knows what is going on, and how to
PS This is my machine at work, similarily configured, and working
correctly (no Hotwheels Mouse here).
My son was saying "Race'a Race Cars Daddy'o!" when he wiggled the mouse.
I guess this is ONE time when I would have been better off booting the
Evil Empire's OS instead, and just raced cars with my son.
