Bug Description

Binary package hint: udev

Various non-standard extra keys of my Samsung N220 (model: NP-N220-JA03DE) don't work in Lucid (and most likely older releases as well). I followed the steps in /usr/share/doc/udev/README.keymap.txt.gz:

1. Find the keyboard device.
root@n220:~# /lib/udev/findkeyboards
AT keyboard: input/event5

2. Dump current mapping:
[see attached orig-map.txt]

3. Find broken scan codes:
Suitable mappings can already be found in /lib/udev/keymaps/samsung-other.
Furthermore, the N220 also requires the workarounds in
/lib/udev/keymaps/force-release/samsung-other.

4. Find out your system vendor and product:
root@n220:~# cat /sys/class/dmi/id/sys_vendor
SAMSUNG ELECTRONICS CO., LTD.
root@n220:~# cat /sys/class/dmi/id/product_name
N150/N210/N220

5. Generate a device dump
[see attached udev-db.txt]

I've also attached two small patches to the corresponding .rules-files, in order to load the appropriate mappings.
Affected version:

I just did the same thing, modifying the 95-keymap.rules. The product is reported as

N150/N210/N220

In order to cover the siblings, the rule should probably be modified to:

ENV{DMI_VENDOR}=="[sS][aA][mM][sS][uU][nN][gG]*", ATTR{[dmi/id]product_name}=="*NC10*|*NC20*|*N130*|*SP55S*|*SQ45S70S*|*SX60P*|*SX22S*|*SX30S*|*R59P/R60P/R61P*|*SR70S/SR71S*|*Q210*|*Q310*|*X05*|*P560*|*R560*|*N150/N210/N220*", RUN+="keymap $name samsung-other"

Here is a debdiff from voria.org. Should also solve #565754 and #468521.

As per https://wiki.ubuntu.com/StableReleaseUpdates#udev%20keymaps I uploaded an udev SRU with the latest keymaps. This now needs to be reviewed/ack'ed by an SRU team member.

Samsung ND10 hotkeys don't work
Samsung ND10 is similar to Samsung NC10.
NC10 is the d 95-keymap.rules. Сan you add udev also support ND10?

I thought that this bug would also fix bug 296489 but it didn't.
