Public bug reported:
Binary package hint: xserver-xorg-video-intel
It's a weird bug. I have quite specific situations and can easily reproduce it.
I don't know how to proceed to nail it down further, but would be happy to
follow instructions.
Steps to reproduce:
1. After boot (or login, or startx), mouse cursor is invisible. Moving the
mouse works - I see highlighting of things under the mouse and can click them,
but don't see the cursor.
2. After launching gnome-terminal, and pressing any key in it, moving the mouse
over the gnome-terminal window restores the cursor! This also works in
emacs-snapshot-gtk, but not in most other windows - not in xterm, nor in
firefox.
3. The mouse cursor also frequently becomes invisible after resolution
switching using Display Preferences. It happens approximately half the times,
but I haven't found a simple pattern. This does not happen when using xrandr
to switch resolutions on the command-line.
When the cursor is invisible, and 2 displays are active (LVDS - internal panel,
and VGA external display), it will only be invisble on one display, on the
other it can be seen. Sometimes it will be on the internal only, sometimes
external only.
When only one display is enabled (internal or external), it will be invisible
on that display.
Doing "xrandr --auto" to activate the second output (both overlapping starting
at (0,0)) will leave the cursor invisible on the original display and show it
on the other one.
[This resembles Bug #145186, but the symptoms here are more complicated.]
This started happening since ~beta6 of karmic, still happens on up-to-date
stable karmic.
It happened with only one out of 2 users on this system! I don't know the
reason for the difference.
I now created a fresh new user, and the bug does happen for the new user.
I'm not sure the problem is in the "intel" driver (user dependency seems
weird), but it doesn't occur with "vesa" driver.
I tried adding:
Option "HWCursor" "False"
to xorg.conf, but the intel driver says it doesn't support it.
