    How can my keyboard crash?

    Keyboard quit working. Logged out, restarted X, logged back in. And it works again. This is the second time this has happend. I have a laptop with a USB keyboard. Both the USB and the laptops built in keyboard crashed.

    Ideas?

    Re: How can my keyboard crash?

    Don't know. I have a USB mouse that sometimes doesn't work, because I have an old USB card. I just unplug it, and then plug it back in again, and then it works. You should try that before rebooting.

    Of course, that doesn't explain why the built-in keyboard's not working.

      I might try that with a USB keyboard, but my built in laptops keyboard doesn't unplug.

        Frankly, I doubt if the problem lies in the usb connector, or the keyboard, since it happens with two different keyboards, especially if it doesn't happen in windoze. If it really doesn't happen in windoze, I would suggest that you take a look at your /etc/X11/xorg.conf file. It's possible that you made a "minor' change, on some occasion and it's come back to haunt you. If so, run "dpkg-reconfigure xserver-xorg". BACKUP YOUR XORG.CONF FILE FIRST. If it does happen in both windoze and Linux, you might actually have a hardware problem!

          Since I restarted my X server, and the keyboards both started working again, I'm leaning away from hardware. I have made a few of xorg.conf changes, but only in the display settings.

            Check the "Input Device" stanza for the keyboard, in xorg.conf. If you'd like you can post it (the keyboard stanza, or stanzas) here so someone who knows what they're doing can take a look at it. I'm wondering whether your problem might be related to the fact that you've actually got two keyboards, the builti-in one and the USB one. If you only have one keyboard stanza, what tells the Xserver which keyboard to listen to?

            I have Dell laptop as well (Inspiron 600M, running Dapper). I have no trouble with the external (PS2) keyboard, but I find that it automatically activates the touchpad rather than the USB mouse unless I jiggle the mouse around (at a yet to be precisely determined point) during the boot sequence, which causes it to figure out that there's a mouse attached. Makes me feel like an even bigger idiot than usual, jiggling a mouse around during the boot process.

              I can type on one keyboard and imediatly switch to the other with no problems. I can type half a sentence on one, and switch to the other. ( Also the build in keyboard has the ble fn keys to raise and lower value ect.)

              Here is my entire xorg.conf
              Code:
              # /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#  sudo dpkg-reconfigure -phigh xserver-xorg

                Re: How can my keyboard crash?

                Hmm, I could have sworn that I said something about only posting the relevant stanza of the xorg.conf file. Anyhow, A bit of Googling seems to indicate that commenting out the line
                Code:
                	Option		"XkbOptions"	"lv3:ralt_switch"
                just might help. At least I don't have that line in the xorg.conf file for my Dell laptop and I only have problems with the mouse! The reason I don't have that line in my xorg.conf file is that I have a fully programmable keyboard from Avant, so I don't need it.

                Of course, my other comment is that, if you're editing xorg.conf anyway, you might as well get rid of all that wacom garbage to simplify debugging from the console.
