Title:
samsung x360 fn-keys work incorrectly
Status in linux package in Ubuntu:
Invalid
Bug description:
I've tried installing the latest ubuntu jaunty 9.04 on the samsung x360 laptop
brightness key presses are ignored, dmesg output includes multiple lines
atkbd.c: Unknown key pressed (translated set 2, code 0x83 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e003 <keycode>' to make it known.
I've tried adding HAL description for X360 to file
/usr/share/hal/fdi/information/10freedesktop/30-keymap-misc.fdi:
<match
key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor"
prefix_ncase="samsung">
<match
key="/org/freedesktop/Hal/devices/computer:system.hardware.product"
contains_outof="NC10;SP55S;SQ45S70S;SX60P;SX30S;R59P/R60P/R61P;Q210;Q310;X05;X360">
After that all the fn-keys are recognized by the kernel, but the problem is
that fn-keys do not send release button events. The similar bug is
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/347623
I've applied similar patch to the kernel's atkbd.c
...
static struct dmi_system_id atkbd_dmi_quirk_table[] __initdata = {
...
{
.ident = "Samsung X360",
.matches = {
DMI_MATCH(DMI_SYS_VENDOR,"SAMSUNG ELECTRONICS CO., LDT."),
DMI_MATCH(DMI_PRODUCT_NAME,"X360"),
},
.callback = atkbd_setup forced_release,
.driver_data = atkbd_samsung_forced_release_keys,
},
...
With the new kernel after
xrandr --output LVDS --set BACKLIGHT_CONTROL legacy
brightness keys seems to work correctly.
It would be nice if you could incorporate corresponding changes into
the main streamline of ubuntu
Thank you
