Public bug reported:
I upgraded to 8.10 a few days ago, and at first I thought I was having
random keyboard/mouse lock-up issues. I then thought this problem only
happened when I switched to battery power. I have finally figured out
that this problem only happens when I use the function keys on my
keyboard to change the display brightness. If I use the LCD brightness
app I do not have a problem.
When this problem happens Ubuntu no longer accepts any input from the
keyboard (except ctrl+alt+bksp to kill X11), the mouse still moves and
allows me to perform left mouse clicks inside of applications and to
items in the status bars, but menu items will not appear when clicked
(the menu item depresses, but the listing never shows).
I have worked around this problem for now by disabling the auto dim when
switching to power mode, and only using the lcd brightness app, but out
of habit I accidentally still hit the function keys on the keyboard, so
this still bites me sometimes.
Restarting X11 fixes this issue.
System Info:
Dell Inspiron 6400
Nvidia GeForce Go 7300
Upgraded from 8.04 to 8.10
Please let me know if there is anything more that I should include.
Thanks
Eric
