Touchpad not working - SuSE 8.2 - Toshiba Satellite A30
Hi all,
I have a bit of an inexplicable problem....
Up until today, on my Toshiba Satellite A30 Laptop running SuSE 8.2 Professional, I had a dual mouse (USB Mouse / Touchpad) configuration in X and everything was running fine.
I booted the laptop today, and for some reason unbeknownst to me, the touchpad has stopped working.
Now.... it isn't a "hardware" issue. If I restart the X server, the Touchpad works UNTIL I move the USB mouse. Then the touchpad refuses to do anything.
If I log into KDE, and launch YaST2 Mouse config, selecting the PS2 mouse (i.e the touchpad) works whilst I'm testing it, but as soon as I apply it, bam, it stops working again.
All the while this is going on the USB mouse is working fine.
I have spent all afternoon inside vi fiddling around with XF86Config, but nothing seems to get things back the way they were.
Now... I have not done anything (to my knowledge) that should have messed things up. I have reverted to a backup XF86Config that was DEFINITELY working before, and the Touchpad still refuses to work. I have re-read the "Second Mouse in XFree86" HOWTO, and my settings are fine. I have booted with a "stock" SuSE kernel and the same problem is there. So if it isn't hardware and it isn't XF86Config, then WTF is it?!?!?
Any help would be greatly appreciated, because the laptop will soon be going out of the window!
Cheers all,
ZB

smcinit
SMCINIT(8) Linux IrDA SMCINIT(8)
NAME
smcinit - initialize the SMSC IrDA controler on various laptops
SYNOPSIS
smcinit [OPTIONS]
DESCRIPTION
Toshiba Satellite 1800, Satellite 5100, Tecra 9100 laptops and may be many other models are provided with a SMCS LPC47N227 SuperIO chip
which is IrDA SIR/FIR capable. The IrDA subsystem of the SuperIO chip is supported by the smc-ircc Linux kernel module. Unfortunately the
BIOS neither configurates the SuperIO chip IrDA subsystem (SIR port, FIR port, dma, irq, IrDA mode, power) nor sets the PCI-ISA bridge to
decode any usable port. Linux kernel is thus prevented to detect the second UART making impossible to use it in SIR mode. For the same
reason, the FIR mode smc-ircc is able to detect the SuperIO chip but, once found the IrDA subsystem unconfigured, fails to install.
While this problem will be fixed in Linux 2.6.x kernel series, the 2.4.x users are frustrated. Daniele Peri, Rob Miller and Paul Hampson
mananged to build little utilities that initialize the LPC47N227 SuperIO allowing smc-ircc IrDA kernel driver to detect and use the SMSC
chip.
My sole work was to put these utilities as one package, easy to install and use.
OPTIONS
-V, --version
Show program version and exit
-h, --help
Show a little help on options and exit
-v, --verbose
Increase the details about actions performed
-t, --tty=device
If specified, the serial device will be unbound from the kernel stock serial driver. It is there to replace an external call to setse-
rial(1) to unset the UART of the device. There is no default value.
-s, --sirio=IO
Set the SIR (serial infrared) I/O port address to IO. Default value is 0x3f8.
-f, --firio=IO
Set the FIR (fast infrared) I/O port address to IO. Default value is 0x130.
-i, --firirq=IRQ
Set the FIR (fast infrared) IRQ line to IRQ. Default value is 3.
-d, --firdma=DMA
Set the FIR (fast infrared) DMA channel to DMA. Default value is 3.
CONFIGURATION
When system startup a script is run from /etc/init.d and which run appropriate SMC intialization utility. This is done before PCMCIA
startup because on Tecra 9100 and other models the orinoco_cs wireless driver will block the I/O region used 47N227 SuperIO.
The only configuration file is /etc/sysconfig/smcinit and the variable SMCCONFIG can be set to "1800" or "5100". By default "5100" value is
used.
1800
for Toshiba Satellite 1800
5100
for Toshiba Satellite 5100 and Toshiba Tecra 9100
The next step is to configure the kernel IrDA stack package to attach the smc-ircc driver. This is Linux distribution specific. The main
thing is that the device should be set to "irda0". Run the following command:
irattach irda0 -s
Distribution specific configuration:
SuSE
Edit the /etc/sysconfig/irda and set IRDA_PORT=irda0
RedHat
Edit the /etc/sysconfig/irda and set DEVICE=irda0
NOTES
The smc-ircc driver is preloaded in kernel. I tested the package only on Tecra 9100 without any additional step, but for Toshiba Satellite
1800 Daniele Peri sugest to put the following line in your /etc/modules.conf (on one line):
options smc-ircc ircc_dma=3 ircc_irq=7 ircc_cfg=0x2e
ircc_sir=0x2e8 ircc_fir=0x2f8
After that run the command:
prompt# depmod -a
If the laptop enter suspend mode, then resume operation the smc-ircc driver will stop working. You need to stop IrDA service, then SMCINIT,
start SMCINIT, and finally start IrDA service. Simply put, the kernel driver must be unloaded, then reloaded.
FILES
/etc/sysconfig/smcinit
Configuration file for SMCINIT startup script. It's shell script.
