Hello, |
| 2 |

Lately I have been experiencing a strange problem. Under X my USB keyboard |
| 4 |
will suddenly stop working. If I press some keys they will not appear in an |
| 5 |
X console or in any other application. There is no warning. It just |
| 6 |
will sporadically stop working. Usually, if I wait for several minutes |
| 7 |
the keys will start working again. |
| 8 |
|
| 9 |
Fortunately, the USB mouse will continue to function normally during these |
| 10 |
episodes. If I then immediately shutdown X using some mouse clicks, I will |
| 11 |
again have a working keyboard. Also, the last few keys I had pressed before |
| 12 |
shutting down X will appear in my console. This would mean that the key |
| 13 |
presses are detected and placed into the buffer but somehow the X applications |
| 14 |
do not receive them. |
| 15 |
|
| 16 |
I cannot pinpoint the start of this behavior to any specific system changes, |
| 17 |
but I suspect that the latest nvidia-drivers may be the source of the problem. |
| 18 |
The problem seems to coincide with one of the several nvidia updates, but |
| 19 |
this is still a guess. |

|
| 21 |
My system is updated daily and I use only the Fvwm window manager (no Gnome or K). |
| 22 |
|
| 23 |
How can I debug this further? Both the kernel log and the X log show nothing |
| 24 |
whatever. |
