I, too, have inherited this problem since upgrading to Lucid. There are a few other characteristics which may help track down the issue: - Update Manager is the worst offender for triggering the problem and also reports that it cannot get mouse focus - Firefox is another program that will always trigger the issue - Most apps that have a Gnome right-click menu can be used to "escape" the block ... - Right click on the top menu of the window with focus - Right click on your target window - Start clicking in the target app - The tricky part can be finding the window that currently has the mouse trapped - particularly if it's buried - Occasionally I have had the situation where the mouse is focused in one window and the keyboard in another - particularly in an xterm. - Once stuck xev does not report window focus changes etc. - VMWare Player, as you might imagine, triggers this behavior and can render a machine almost useless
My hardware is as follows: - Intel Core 2 Quad Q8400 - 8Gb RAM - Gigabyte EP45-UD3l mobo - Logitech wireless mouse - Gigabyte GV-R435OC-512I - ATI HD4350 based graphics card - ATEN CS62DU 2 Port DVI USB KVM - SABRENT USB to PS/2 (Dual PS/2) Converter Adapter Cable Model SBT-PS2U - NMB RT8256CW keyboard (circa 1996) - assorted SATA disks etc. I am running with ACPI=off noapic in the startup line (and still see all 4 cores in system monitor) As much as I'd like to see this issue fixed I'm also prepared to buy a different mouse if someone can assure me that the problem would go away. I've almost got the point of turning the machine inside out and running Windows 7 as the host with a Linux guest under VMWare. However since I run a mail server, samba domain controller, web server, mysql server etc. you can understand that would be a last resort! Any advice gratefully received. Also if you need me to test anything I will be happy to help where I can.
