Disableing wireless with Fn+key blocks the computer

[Alex Moldovan]

Binary package hint: udev

If I press the key, (when wireless in on and working) the wireless led goes of, and the screen goes black (with just a white dash and mouse arrow), and the computer remains completely frozen. After reboot, the operating system is loading, I hear the login sound, but no desktop. I succeeded to reboot the machine with Alt+SysRq key combinations. At reboot the desktop loaded correctly, so I decided to repeat the action.I enabled and then disabled the wifi with Fn+F2 and I go the black screen with the following message:

[13.101779] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
[93.487791] Kernel panic - not suncing: HwThreeWire(): CmdReg: 0XFF REIWE bits are not clear!!
[93.488478] [drm:drm_fb_helper_panic] *ERROR* panic occured, switching back to text console

Computer is frozen again.

The wireless card works on the system, moreover when I press the same key combination (Fn+F2) to ENABLE the wifi, everything WORKS as it should be. The wifi led goes on and I can connect to a wireless network. When I try to disable it, the black screen comes up with a white dash and the mouse arrow, and nothing moves.

[MacRules (macrules)]

I am not sure if this is related, but I have similar behaviour on my Mivvy G310 netbook.
When pressing Fn+volume up/down/mute or webcam key, I get repeated key events and can no longer use my keyboard.
Mouse keeps working and when switching from terminal i can go on.

If this is related and anyone needs more info, please let me know.

I'm facing similar simptoms as MacRules.
The system is an Olivetti 820 notebook running lucid from a Live CD. After using Fn volume +/-, the keyboard locks and open windows cannot be moved or resized. Also, the upper menu bar becomes non-responsive.
I have tested eight different distros, but the only two that work for me are Ubuntu 8.04 and Trisquel 2.2.2. This two are the only that use xorg 1.4.0.90.

Running showkeys in a text terminal shows that the volume up and down keys (Fn F5 and Fn F6 in my system) only issue a key press event, but NO key release event.

Ronald,

Can you re-test this on 10.04.1 and update the bug with your result?

lucid has seen the end of its life and is no longer receiving any updates. Marking the lucid task for this ticket as "Won't Fix".
