Red Hat Bugzilla – Bug 227239
Multimedia Keypress Causes X Crash
Last modified: 2018-04-11 15:32:35 EDT
Description of problem:
Well, as the summary says, if I press any of the multimedia keys on my MS
Natural Keyboard Pro keyboard, it crashes X and dumps me
back to the ttys. (I start in Runlevel 3.) This happens either in
Xfce4 or in Gnome, so I'm guessing it's X that is doing it.
The only two keys I've tried is the "Back" and "Mail" MM keys. I was
trying to map their keycodes in xev, but bam. It also crashes even
if xev is running, so I can't blame it.
Version-Release number of selected component (if applicable):
I think I have: xorg-x11-server-Xorg-1.1.1-47.5.fc6
I'm not too sure if that is the correct xorg rpm.
How reproducible: Always
Steps to Reproduce:
1. Start Xfce4 or Gnome
2. Press a multimedia key.
X crashes dumping me back to the ttys.
A keycode is sent. Not much more beyond that since
I can't map the keycodes until the keyboard stops

Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Removing xorg.conf and starting x again does *not* cause a crash upon a
multimedia key press.
The explanation of your problem is really simple -- your original xorg.conf used
nvidia binary-only driver, which crashed. Of course, when RedHat's Xorg
autconfigures it never uses stuff like that, so now you are using open source nv
driver, which doesn't use all the functionality of your video adapter, but
apparently it works better. Standard text for nVidia binary-only driver users
Thanks for the report. For users who are experiencing problems
installing, configuring, or using the unsupported 3rd party
proprietary "nvidia" video driver, Nvidia provides indirect
customer support via an online web based support forum. Nvidia
monitors these web forums for commonly reported problems and
passes them on to Nvidia engineers for investigation. Once
they've isolated a particular problem, it is often fixed in
a future video driver update.
The NVNews Nvidia Linux driver forum is located at:
Once you have reported this issue in the Nvidia web forums,
others who may have experienced the particular problem may
be able to assist. If there is a real bug occuring, Nvidia
will be able to determine this, and will likely resolve the
issue in a future driver update for the operating system
releases that they officially support.
While Red Hat does not support the proprietary nvidia driver,
users requiring technical support may also find the various
X.Org, XFree86, and Red Hat mailing lists helpful in finding
X.Org mailing lists:

I confirm that the X server crashes when any multimedia key is pressed. I have USB keyboard Genius Slimstar. The crash is not caused by proprietary nvidia drivers because I have ATI RS690. I do not have any xorg.conf. This may be relevant:
I think this bugreport should be reopened.

Go and file a new bug about that (or find the most approriate one among https://bugzilla.redhat.com/buglist.cgi?quicksearch=component%3Axorg-x11-drv-ati), but this bug is for nvidia driver, not ati.
sorry, in the last sentence you should read "chip" instead of "driver"
