--- Comment #7 from Michal Zatloukal <myxal....@gmail.com> 2010-12-27 08:11:55 --- (In reply to comment #6) > in this case, brightness hotkeys works in the same way as described in bug > #19592, right? Yes and no - down always worked in 2-step increments but up was simply unpredictable - sometimes it went up 2 steps and stayed there, sometimes it went up 2 steps briefly and went back to the level it was before the keypress. Now, I have two pieces of new info. Few days ago I stayed a while longer in the rc3 kernel (I rebooted after 2 days - probably 2 suspend-resume cycles and quite a few mode-switches LVDS<->VGA later) and when I was about to reboot I noticed the hotkeys were broken here too! Can the relevant info be found in dmesg output? If so, I'll see if I can reproduce the situation. Second, the /sys/module/video/parameters/brightness_switch_enabled is set to Y in current Ubuntu kernel. Setting it to N fixes pretty much everything - hotkeys increment and decrement properly, powerdevil detects the keypresses and shows the brightness level as it's increased/decreased correctly, showkey -s detects 4 characters on quick keypress for both keys, and brightness is adjusted in tty as well as in X. Down: 0xe0 0x4c 0xe0 0xcc Up: 0xe0 0x54 0xe0 0xd4 I'm not sure I understand from #19592's comments how this is intended to work - is this merely this laptop missing from/being in some white/blacklist incorrectly, or is this an ACPI bug or intel-driver bug? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
