Public bug reported:
Binary package hint: x11-xserver-utils
This problem is happening under GNOME, KDE, and Openbox window manager
sessions.
I've deleted any ~/.Xmodmap files, so these sessions are not modifying
the xmodmap prior to my execution of the described commands.
Steps to reproduce:
1. Start a new X login session. It doesn't seem to matter which desktop
environment is selected, as this bug is reproducible under KDE, GNOME,
and Openbox.
2. Open a terminal.
3. Type one of the following commands:
$ xmodmap -e 'clear Lock'
OR
$ xmodmap -e 'remove Lock = Caps_Lock'
Result:
An error message similar to the following is displayed:
X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 118 (X_SetModifierMapping)
Value in failed request: 0x17
Serial number of failed request: 11
Current serial number in output stream: 11
The serial number values vary but the other information is consistent.
Requested information:
1) Release info:
$ lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04
2) Package version:
$ apt-cache policy x11-xserver-utils
x11-xserver-utils:

3) Expected result
Prior to my recent upgrade to Lucid (Ubuntu release 10.04), I was able to
unmap the Lock modifier without problems. As a vim user I find it quite useful
to map the [CapsLock] key to Escape, and prefer to disable the Lock modifier
entirely: as I rarely write anything in all caps, I seldom have any use for it,
and an accidental activation of it can cause minor confusion when editing files
in Vim.
My previous ~/.xmodmap file used the "clear Lock" directive to disable the
Lock modifier. Upon rebooting after upgrading to Lucid I discovered that this
functionality was no longer activated, ie that the Caps Lock key continues to
control the Lock modifier's state.
I expected it to be activated and for the Caps Lock key to not affect the
Lock modifier state.
4) What happened instead:
The Caps Lock key continued to control the Lock modifier's state. The error
message given above was output in response to an xmodmap command to clear or
remove that functionality.
Also: please note that my exclusion of gdm debugging information was not so
much due to privacy concerns as because I haven't run it in months. Although
this install is an Ubuntu install, I installed the kubuntu-desktop metapackage
some time ago, and so am using kdm rather than gdm. In any case this seems
unlikely to be affecting xmodmap functionality.
