Summary - xorg keyboard 'stuck' with KMS-enabled kernel
Task Type - Bug Report
Category - X Window System
Status - New
Assigned To - 
Operating System - x86_64
Severity - Low
Priority - Normal
Reported Version - -current
Due in Version - Undecided
Due Date - Undecided
Details - Hello,

I'm unsure what causes this problem, but I'm trying to describe it...

When X is running, sometimes one of the keys gets stuck and starts to flood the shell I'm working in and the keyboard becomes unresponsive (no VT switch, nothing). When I'm lucky, I can use the mouse to quit the window manager from its menu, but sometimes even mouse buttons fail to work. In such cases, I must power the machine off.

It all began to appear in the last few weeks, but strangely, some sessions are free from the error. Last night I was up for hours without hitting the bug, but today I had to restart X at least ten times.

At the time of these problems, nothing was recorded in neither the system nor the Xorg logs, and I had nothing else running except Firefox. I have never encountered the problem from the console.


Software: -current (1.2pre1), openbox, pypanel, mrxvt, firefox, cpuspeed.
I have a very minimal system, most of the rc scripts are slightly modified. I prefer disabling the framebuffer.

Hardware: IBM ThinkPad x61s, c2d 1.6GHz, SSD drive, 2GB RAM, Intel 4965AGN wireless, unnecessary devices disabled/blacklisted.

What didn't help:
- enabling the framebuffer
- using the Xorg 'vesa' driver instead of 'intel'
- turning off gpm

What seems to help:
- using kernel 2.6.30-fw3 (from 1.1)

I had i686 on this system which was re-installed from bare metal with x86_64, and both archs had/have this problem.

I will test upcoming versions of xorg-server/xf86-video-intel/kernel etc. and report how they work.

Please post a comment here if you find reference to this bug elsewhere, in other distributions!

thanks && best regards
