Samsung win 10 brightness control patch code#

Turns out this is a problem with lots of laptop keyboards: look at the thousands of lines of hacks in drivers/ input/keyboard/ atkbd.c in the Linux kernel source. 'After a while I discovered the problem was that some of the fn-keys weren’t sending key release events (easy to see in xev or with lshal -m). It seems that the problem is related to the keys not sending events. Maybe someone can get this fixed for the upcoming Karmic?

So I patched the kernel, using same code as here: a=commit h=b6edef2ac7b84ba90192ec1b8947949ebc99e99c, but I put DMI_MATCH(DMI_PRODUCT_NAME, 'R510/P510') instead of DMI_MATCH(DMI_PRODUCT_NAME, 'SQ45S70S') Then there is another problem, the same encoutered here: : the key release event is not sent. I currently do not have other key working yet (wifi on/off, backlight.), I will try to have them working and keep you informed. I wrote a little script (brightness.sh, see attachment), and then binded the brightness down/up keys to that script, using the gnome key-binding utility.

I recompiled the kernel (using blog.avirtualho me.com/ 2009/04/ 29/how- to-compile- a-kernel- for-ubuntu- jaunty/)Īfter that, the key works, but brightness does no adjust, it seeems there is a bug/missing feature in the nvidia driver.Īfter some googling, I tried smartdimmer (using nvclock should also work), and that one works. So I patched the kernel, using same code as here: kernel. net/ubuntu/ +source/ hal-info/ +bug/295251 : the key release event is not sent. Then there is another problem, the same encoutered here: https:/ /bugs.launchpad. (tu put in bootmisc.sh or another script in /etc/init.d you then add to the runlevel scripts) I had it finally working, perhaps not the properly way, but working.Īt boot time, I add to attach keycodes to the brightness keys (adding fdi definitions in hal does not seem to work): I recently bought a R510 laptop, installed jaunty onto, and encoutered the same problem. atkbd.c: Use 'setkeycodes e008 ' to make it known.Īre gone now and HAL shows the keymap data not shown before: atkbd.c: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0). atkbd.c: Use 'setkeycodes e009 ' to make it known. atkbd.c: Unknown key pressed (translated set 2, code 0x89 on isa0060/serio0). atkbd.c: Use 'setkeycodes e004 ' to make it known. atkbd.c: Unknown key pressed (translated set 2, code 0x84 on isa0060/serio0).

I forgot to mention that I'm using fresh install of Jaunty Beta with current upgrades.Īfter the HAL was restarted I've also noticed that the dmesg warnings present before:
