Touchpad functionality dissappeared for no apparent reason!
Until recently, my Dell Latitude L400 touchpad was being happily detected by my Linux
kernel (2.6.7) at bootup, and was working fine in X, but then mysteriously dissapeared?
I suspect a blundering apt-get install of udev which appeared to erase /dev/fd0.
However, I was able to recreate /dev/fd0 by re-booting with the floppy drive attached,
(after apt-get purging udev), but re-booting without my USB mouse attached has not
revived my touchpad :-(
Attached is a relatively short diff of my last touchpad-successful boot compared with the
following unsuccessful one. As can be seen from the diff, it was being recognised as a
"SynPS/2 Synaptics TouchPad on isa0060/serio1". Since then it hasn't been recognised
once!
If you think my suspicions may be correct and I need to recreate the device file somehow,
how would I do that and what would I call it?
Any help much appreciated!
TIA
