When I was running an application then on pressing a key the following message came:
X Error of failed request:* BadMatch (invalid parameter attributes)
* Major opcode of failed request:* 42 (X_SetInputFocus)
* Serial number of failed request:* 7345
* Current serial number in output stream:* 7347
It seems to be something related to graphics, but can't understand. After the above error came the application got terminated.
