complications of copying system

leftty · 10-02-2009, 12:55 AM

I copied my Slackware64-13.0 system to a partition on another disk using rsync -avxP. After modifying the fstab and re-installing lilo, the copied partition boots and everything seems to run as before. . .

except the (usb wireless) mouse requires replugging after x starts. The serial keyboard works before x starts, but I have to switch to a usb keyboard after starting x.

Why would this be?

Do you have the "hid", "usbhid" and "ff_memless" kernel modules loaded. I use a Logitech wireless mouse on my laptop. Grep'ing lsmod for 'hid' returned this modules.

Try using a different USB port. My wireless dongle works better on the left than the right hand side. One port may be better able to supply the power needed to the dongle.

For comparison, this is what the xorg.conf section looks like for my wireless mouse.

Code:

Section "InputDevice"
  Driver       "evdev"
  Identifier   "Mouse[1]"
  Option       "HWHEELRelativeAxisButtons" "7 6"
  Option       "InputFashion" "Mouse"
  Option       "Name" "Logitech VX Nano Laser Mouse"
  Option       "Pass" "3"
  Option       "Vendor" "Sysp"
  Option       "evBits" "+1-2"
  Option       "keyBits" "~272-287"
  Option       "relBits" "~0-2 ~6 ~8"
EndSection

Sometimes removing a device and reinstalling it it can help.

Since you did change Lilo, check your lilo.conf file. Some kernel options such as noacpi can cause some hardware not to function. Often because it can't receive an interupt.

What bothers me is that I never had to add a special section to my xorg.conf on the original system. The usb keyboard works before launching X, as does the serial. They both go dead when I start X the first time. The usb is repluggable, but not the serial.

The problem lies with module management. What about starting X is unloading the module needed to control my serial keyboard. What are some good tools/techniques that can tell you what modules are associated with which devices?

Are you using HAL?
