Single Clicks Seen as Double Clicks
Just set up a nice new 64-bit desktop. Weird shit: Firefox menus won't open; Web-page drop-down boxes won't drop; then pastes into BASH are double each time — the penny drops. xev confirms that each mouse click is interpretted as two clicks. xorg.conf needs some work. . .
The mouse is a Dell USB optical; I have in place only the default xorg.conf mouse configuration. This fixes things:
Section "InputDevice" Identifier "Configured Mouse" Option "CorePointer" Option "Device" "/dev/psaux" Option "Protocol" "ImPS/2" Driver "mouse" EndSectionProbably Xorg was not figuring out that Protocol should be ImPS/2.
