Comment 23 for bug 571534

I have been using 10.04LTS on two machines, and just installed it again on a Toshiba Satellite L305-S5918 for someone else. I am experiencing a similar problem where the mouse cannot click on things. Upon restart, things go back to normal. I tried using Microsoft wireless 5000 mouse, Microsoft IntelliMouse, and the touchpad on the laptop with the same result.

What happens is that the pointing device, (anyone of the above,) would lost its ability to get focus on an object. However, I can still "tab" my way around and use keyboard to execute "clicks".

I was able to finally find some additional info that may be helpful. When it fails, I can do Alt-F4 to close the application and get back to desktop, and at that point, I will re-gain control of mouse to launch another application. I then launch Sudoku, a game that comes with standard install, and found the following issue.

When I click on a square for the first time, it will get focus. I I move to another square and click, my focus will not move, but rather, the original square will get the click and gets into the number selection screen. If I do Alt-F1 to get out of the selection screen, I can move to another square using keyboard, and move the focus there, but not with the mouse click.

Now, what may be most significant find is that when the focus is moved to a second square using keyboard cursors, and I click on the mouse anywhere on screen, the click is sent to the original square, and opens up the selection screen for that square, not the new square.

On all the machines that I have 10.04LTS installed, only this one is intel based. All others have AMD solution. Another observation is that when my initial installation is completed, and the CD ejected, the screen keeps saying there is an error. I found that it should not be a concern with on line installation document, but just some more information to share.

Also, when it happens, I noticed that screen saver seems to be locked into the background. As soon as I close the focus grabbing app with AltF4, the login screen will appear. I don't think screen saver is the cause of the problem, as I have disabled it and the same problem still occurs.

Another observation. On the working machine, under System-Preference-Mouse, I have only two tabs, General, and Accessibility. On the offending one, I have three tabs, General, Accessibility, and Touchpad. I don't know why there is a Touchpad tab on the offending machine, as both machines have Touchpad on them.

I hope this could be helpful. Good hunting!
