           Summary: USB-mouse hangs sporadically during work in KDE4 in
                    OPENSUSE >= 11.4,
    Classification: Unclassified
                OS: Linux
          Reporter: sans.souci at t-online.de
          Hardware: Other
            Status: UNCONFIRMED
         Component: general
           Product: unknown

Since OPENSUSE 11.4 + KDE4, mouse connected via USB  hangs sporadically.
This occurs apparently mainly during editing work, e.g. of mails in
Thunderbird.
Sometimes this happens also in other circumstances that i dont remember
exactly.
I can still move the mouse pointer, but i cannot trigge any action with it,
e.g. setting cursor 
or clicking on buttons or on close-, maximizing-, minimizing buttonds of opened
applications. 
When error occurs during editing a mail, the text background is colored while
moving the mouse pointer,
but i am not able to activate the cursor again at the required test position.
Any other manual activity still seems to be possible. 
I still can move select menue items by moving the up/down/left/right position
keys.
Further i can invoke the logoff/shutdown selection facility by ALT CNTL Del
keys.
This enables me to logoff the KDE session and re-logon. 
During logoff i receive a request to save edited content. 
The saving can be done also by moving the position keys accordingly. 
After logoff (not shutdown) and re-logon KDE4 the mouse is ok.
This workaround works in the most cases, but in seldom cases data are still
lost,
when during logoff the text background is filled with color (means "delete
it!).
(

This seems to indicate that only KDE4 is involved in this error,
 since there is no Kernel startup necessary to remove the problem. 
Only logoff/re-logon is necessary.. 
Therefore i decided to write this error report against KDE4.

Error didnt occur during OPENSUSE <= 11.3.
I use VAIO VGN CS11S with NVIDIA drivers. 
Install of NVIDIA drivers from NVIDIS webside does not remove the error.
During error, i also cannot use the "mouse substitute keys" at the laptop.
Also using another USB connection doesn't help.
I use DuaL Boot with Windows Vista.
Error doesn't occur when working with Vista.
In Opensuse 12.1 i have installed KDE4 and (very recently, yesterday) Gnome.
When i have worked with KDE4,thereby handling many actions with Dolphin anf
Furefox, 
the problem has occured again. 
I will look if this problem occurs also when i work with Gnome.


Reproducible: Sometimes

Steps to Reproduce:
1.I havent found a method to reproduce the error.

See above.
Sometimes data are lost. Therefore the severity of this problem is a little
stronger than normal.
