I have an Acer Asipre S7 with Ubuntu 14.04 LTS, and after updating and rebooting, some unusual behavior occurs when I use the arrow keys or Delete. What seems to be the TouchPad indicator appears in the upper right, and the up and down arrows don't work, nor the delete key. The machine worked just fine last week.
It happens when I try and up or down arrow in a text document too, although left and right work fine.
Edit: I found the Keyboard Layout chart, and the up, down and right arrows don't light up when I push them. If I hold the hey and press down the volume does go down. If I hold and press the up arrow, Chrome launches.
I have looked in the Keyboard settings, but keyboard shortcuts, and nothing looks awry. I'd really appreciate some help!
Edit 2: Just learned about keyboard-configuration, but it doesn't seem to help:
Edit 3: Here is the content of /etv/keyboard/default
# Check /usr/share/doc/keyboard-configuration/README.Debian for # documentation on what to do after having modified this file. # The following variables describe your keyboard and can have the same # values as the XkbModel, XkbLayout, XkbVariant and XkbOptions options # in /etc/X11/xorg.conf. XKBMODEL="acer_laptop" XKBLAYOUT="us" XKBVARIANT="" XKBOPTIONS="" # If you don't want to use the XKB layout on the console, you can # specify an alternative keymap. Make sure it will be accessible # before /usr is mounted. # KMAP=/etc/console-setup/defkeymap.kmap.gz
