[Bug 1318040] Re: bbswitch prevents suspend and taints kernel
Still facing the issue with kernel 4.2.0-23-generic, gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2), bbswitch-dkms 0.7-2ubuntu1, no bumblebee package installed.

Christopher, I am not sure to understand your question. Did you mean, did the problem appear before Raring if the setpci method was not used? yes, for example, in 12.04 (comment #46). I didn't try to disable the Intel card in a release prior to Raring, I suppose that situation would be similar as that reported in Bug #1225067. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1178796 Title: 8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in /sys/class/backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1178796] Re: 8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in /sys/class/backlight
** Description changed: It used to work with the workaround suggested at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which modifies asus-brn-down.sh to use the "setpci" method. But I had forgotten that workaround and I suspect that upgrading to Raring removed my modified scripts. So, in the original description of the bug, I thought it was a regression. But it's probably not a regression as the brightness control has apparently never worked off- the-shelf.

[Bug 1178796] Re: [Asus UL80VT] Backlight control does not work, but there are entries in /sys/class/backlight
I have updated the description according to my last message. I think the bug is not a regression and it has never worked directly. It would be nice to fix it after 3 years of existence. ** Description changed: - Not working since the upgrade to Raring. Used to work on 12.10. + It used to work with the workaround suggested at + http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness + which modifies asus-brn-down.sh to use the "setpci" method. That + workaround probably still works with Raring. + + But I had forgotten that workaround and I suspect that upgrading to + Raring removed my modified scripts. So, in the original description of + the bug, I thought it was a regression. But it's probably not a + regression as the brightness control has apparently never worked off- + the-shelf. Not working neither with linux- image-3.9.1-030901-generic_3.9.1-030901.201305080210 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.1-saucy/ Hotkeys are detected, showkey -s: Fn+F5: 0xe0 0x4c 0xe0 0xcc Fn+F6: 0xe0 0x54 0xe0 0xd4 I also attach the results from tests described on https://wiki.ubuntu.com/Kernel/Debugging/Backlight.

But echo 8 > /sys/class/backlight/intel_backlight/brightness makes the screen dark, moreover /sys/class/backlight/intel_backlight/max_brightness = 2583660 - on 3.9.1, no brightness change but the KDE notification pops up with only 3 levels (0, 53, 100%) Test with video.use_bios_initial_backlight=0: - on 3.8.0-20.31-generic, no change.

I probably had tweaked my acpi script according to the information given at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which suggests to use setpci. And probably, the modified scripts /etc/acpi/asus-brn-down.sh (and -up) were deleted during the upgrade to raring.

Hi Christopher, I have tried ubuntu-12.04.2-desktop-amd64.iso and ubuntu-12.04-desktop-amd64.iso: the brightness applet reacts to the hotkeys but the brigthness of the screen does not change. I thought it was working before 13.04 but I don't remember whether I tweaked something. Maybe I added acpi_backlight=vendor, shall I tried the same old-releases with acpi_backlight=vendor?

[Bug 1178796] Re: [Asus UL80VT] Backlight control does not work, but there are entries in /sys/class/backlight
Well, I'm lost. It seems not related to linux-image, as the kernel image 3.5.0-17.28 (quantal release) does not work either. So it may come from another package update, acpi-support? other notes: - sudo setpci -s 00:02.0 F4.B=HH with HH between 0 and ff works. - echo 258366 > /sys/class/backlight/intel_backlight/brightness works (values between 0 and 2583660) - /etc/acpi/asus-keyboard-backlight.sh looks for /sys/class/leds/asus\:\:kbd_backlight.

Reboot is required because it's a problem with a driver, which fails when loaded and leaves the device in a bugged state, which eventually prevents suspension. >From bug #1169984: === Alternate workaround === IF you have no intention to use the HDMI audio, blacklisting the HDMI audio module will probably prevent this issue.

For me, it is a consequence of bug #1169984 related to the HDMI audio driver which prevents pm-powersave to terminate, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1169984. You can check /var/log/pm-powersave.log.
