Comment 14 for bug 229123

I am also having this problem on Ubuntu Hardy 8.04.1, however it is so far seems to only effect my x86_64 machine. My other machine only running in 32 bit mode with same window settings and packages has never presented this problem.

The exact details are that to get any window to focus(except firefox) I had to click directly on the window titlebar. For some reason when all the normal windows (terminals,gnome and kde apps, system configuration windows) were requiring a direct click to the titlebar to gain focus, my firefox windows continued to receive focus on any click withen the firefox client window area like one would expect with 'click to focus' mode.

At one point I noticed while working under kde/kwin with a couple of terminals open that when I attempted to double click an unfocused terminal to select for a paste that it was selecting the same general location in my currently focused window instead of directing the mouse click to the window the mouse was over, maybe this is why the window never got its focus request...

I tried several desktop environments to fix this with no avail, (although 'click to focus' magically started working on its own again, in the MIDDLE of an Xsession(was not attempting any configuration changes or fixes at the time...) while I was working on other things, surprised me to have it working after 3 days without it working with multiple reboots, package resets, and configuration changes)

This problem presented itself (and would not go away) under different desktop systems. I tried the following:

Gnome/metacity (my default environment)
Gnome/compiz
Gnome/icewm
KDE-4/kwin-4 (from kubuntu-kde4-desktop metapackage)
KDE/kwin (from kubuntu-dekstop metapackage)
KDE/compiz
KDE/metacity
KDE/icewm
KDE/blackbox

Which leads me to believe it is an issue at the xorg event or input level and not a configuration issue with a given window manager.

I also did a complete uninstall of compiz packages which did not solve the problem.

I also tried a forced --resinstall of all xorg and gnome packages which did nothing to fix the problem, along with removing all my .* files and directories related to the window managers.

The other focus modes, sloppy and mouse over, appear to work. I also tried setting the focus prevention between off,low,high,really high with no discernible effect when in 'Click to Focus' mode. Something else I noticed in the compiz ccsm manager that the 'Click To Focus' option under general options has blue text, and did not retain changes made, but stays with the default 'Click To Focus' enabled.

I am attaching a file that contains my .xsession-errors and my package list

In addition I have the following hardware (in twinview mode)
AMD Phenom(tm) 8650 Triple-Core Processor
Asus M3N-HD/HDMI motherboard
NVidia GeForce 8800GTS 512 (using driver version 169.12 from the nvidia-glx-new package)
Along with a Belkin USB KVM on one monitor to my 32 bit system with the mouse and keyboard being a microsoft wireless plugged into the belkin.
