The SHIFT KEYs on my HP Pavilion g4 is non working.

Hi,
thanks for your feedback.
Would you please paste the output message of the following commands?
lspci -nnvv
xinput
sudo showkey ( together with pressing the SHIFT keys)

If possible, it would be better to paste the output message of the command "dmesg" and "sudo showkey" together with pressing both of the shift keys when this issue happens.

Thanks.

Hi Tai,

i tried both the commands you asked me and when i press both the shift keys together i do not get any output, the system does not respond. anyways this is the output

        meghana@meghana-HP-Pavilion-g4-Notebook-PC:~$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ HP Webcam-101 id=9 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
    ↳ HP WMI hotkeys id=12 [slave keyboard (3)]
meghana@meghana-HP-Pavilion-g4-Notebook-PC:~$ sudo showkey
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 28 release

thanks.

hi, what is the output of the command:

lspci -nnvv

hi,

Hi, thanks for your feedback.
Both of the current certified HP Pavilion g4 use AMD chips, and your machine uses intel chips,
so I could not verify this issue immediately without further study.
The certified HP Pavilion g4:
http://www.ubuntu.com/certification/hardware/201212-12396/
http://www.ubuntu.com/certification/hardware/201209-11638/

For left shift the keycode should be 42 and for right shift it should be 54.
According to your information above,
the hardware of the keys(your shift) seems not to work
because it did not show any keycode but only "keycode 28 release"
which is ENTER.

Did you forget to press SHIFT after applying the shift keys?

1. Please try to use another keyboard to test again.
2. If you are sure the keyboard hardware works normally and it still no keycode shown. Please apply the command 'ubuntu-bug linux' to file a bug report on Launchpad. Then there will be more people come to help you and you could also improve Linux and Ubuntu as well. Thanks for your contribution.
