I have recently installed Squeeze on my laptop. Everything seems to be working except for the brightness control. Dmesg says that ACPI failed to set brightness. I was wondering if there is a workaround or if there is a driver I am missing?
My laptop is a Dell Studio 1569. [ 7329.281812] ACPI: Failed to switch the brightness
This error happened when i booted my system :
Failed to start Load/Save Screen Backlight Brightness of backlight:acpi_video0. See systemctl status systemd-backlight@backlight:acpi_video0.service' for details.
I'd been trying to get into Linux before I bought it so I figured that I would try to get it onto my new Mac so that I could use it wherever I am. I decided to try Debian Lenny 5.0.3 a whirl after reading about all the different distros available. I've successfully installed it and I can get to it with rEFIt, and I have quite a few things working such as the video drivers and wifi. However, I've had trouble getting it to a level where it'd be usable away from home. Here are the main problems I'm worried about:
1) I installed pommed but I still can't use the brightness keys to change the screen brightness. I'm not sure if there's some other workaround for this?
2) I tried some recommended power management packages (gnome-power-manager) but it doesn't seem to be accessible or functional right now. I don't have any way to control it or get to it that is obvious to me. Is an icon or anything supposed to appear on the task bar when you install or what? Getting some sort of power management on here is important because it gets really lousy battery life otherwise.
3) Being a Macbook, there's no right-click button. Multitouch would be really nice (two-finger scrolling!) but I'd be OK with ANY way to right-click with the touchpad. I have a wireless USB keyboard/mouse combo that works at home at least . . . right out of the box too!
4) I've seen some packages called the Mactel PPA, but they are made for Ubuntu. Since Debian and Ubuntu are so similar, is there any way to make those work on Lenny? I think that if I got those to work, I could fix some of the problems above. Or do I have to install Ubuntu?
5) I just noticed that the sound doesn't seem to work yet either.

I'm having a really strange problem, when I turn on openSUSE, the brightness is fine.owever, as soon as I log in the brightness gets obnoxiously low. I have a MacBook Pro 7.1 with openSUSE 11.4 KDE
View 5 Replies View RelatedEver since I started to tinker with GNU/Linux on my machine, ACPI has been a thorn in my side.
I can't find any BIOS updates or DSDTs for my laptop, either.
The only distro I've ever gotten to boot without acpi=off is Fedora 20 with the 3.11 kernel and nohz=off parameter. Which leads me to believe a change in the kernel after 3.11 is to blame.
Anyways, I have installed wheezy 7.8 XFCE with LVM encrypted, but alas I am stuck booting with the ACPI=off parameter.
The installation CD booted perfectly, with my wireless card working (an indication of ACPI functioning) as well.
This leads me to believe that it is possible to have a stable wheezy install on this machine.
The install disc used the parameters: video=vesa :ywrap,mtrr and vga=788.
I tried these, but the boot hanged after "switching to clocksource: acpi_pm".
How I could track down the problem with ACPI on my machine?
During boot (and in dmesg) I get the following message:
[6.782835] ACPI: Invalid PBLK length [7]
Also possibly related, whenever I close my laptop lid, kacpi_notify and kacpid eat up the cpu, and the screen doesn't actually blank.
I have an Asus EEE Box EB1012 running Debian Jessie (headless with no GUI installed).
I'm trying to get the power button on the front of the machine to put the computer in suspend.
If I run pm-suspend from the command line, it suspends correctly and also recovers correctly by pressing the hardware power button.
Originally, pressing the power button (while running) would shut the computer down.
The acpi power button event script was set to run the command "/sbin/shutdown -h -P now".
I changed it to "/usr/sbin/pm-suspend", and restarted the acpi service/rebooted the computer (I tried both), but the power button still cause the computer to shut down.
I also tried setting no action (empty string) for the power button event, but still the power button caused shutdown.
Is the acpi system getting bypassed somehow? Is there another system to configure instead?
I have tried both DVD and CD (both are MD5-checked) of both Lenny 5.0.8 and Squeeze RC on my HP DV7-3074CA. (a.k.a 3085DX)When I choose a graphic install, it just hangs after loading the initial files.When I choose the normal install, It gives the following error:
[1.383207] ACPI: EC: Input buffer is not empty, aborting transaction.
Is there a boot command I can input to override this? I tried removing the battery slot, but the only difference is that that message does not appear, but the setup hangs anyway.
UPDATING:Tried "pci=noacpi" but that did lead to a kernel panic.[1.547564] Kernel panic - not syncing: Attempted to kill init!
I have a strange problem with the ACPI in my laptop, the problem start some days ago, I don't remember exactly the day.
The first symptom is with de Gnome Power Manager, only show me when I disconnect de AC power, but when connect it again the Power Manager icon disappear and the energy battery stay in the same value.
After search for a while, all the post I read talking about the /proc/acpi/battery directory, but this directory not exist on my laptop.
I have a laptop Lenovo G460. My OS is Squeeze. My Kernel is 2.6.38-bpo.2-amd64, because the 2.6.32 version of the kernel don't recognize well my audio card.
I can't attach the dmesg and the lsmod output because I receive a message "Sorry, the board attachment quota has been reached.", both file are compressed.
I installed Debian Lenny on my old IBM thinkpad R40e but i can't change the brightness either with the Fn keys or with the brightness control debian has. i have searched around and it seems to be a problem with linux on IBM thinkpads but i don't know that much about this sort of thing so any help would be appreciated. if you need any more info then just ask.

I'll provide this info, if this can help to improve Debian on this hardware. I always see this ACPI errors in dmesg:

My laptop brightness gets set to maximium each boot.
Just wondering if this is the case for other laptop users. I have a Lenovo Thinkpad SL500 (GeForce 9300M GS) and am running Testing.
Ideally I'd like it to remember my last setting (which is usually the lowest). It'd be nice not having to turn it down each time I reboot/power-on.
It actually starts off at a low setting but during the boot process (before gdm and just after the "Waiting for /dev" line I believe) it suddenly gets set to max.
When I first install debian I couldn't change the screen brightness at all not manually nor with function keys, but I tried some of the solutions I found on the internet and now I can change the brightness manually (from the power management or the battery icon) but when I use the function keys it takes them like 2 to 3 minutes to respond and cause the system to hang (even mouse curser not responding) and then I'm forced to manually reboot the system, here is some information :
Code: Select all$ ls /sys/class/backlight/
acpi_video0 intel_backlight
Code: Select all$cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

And I've tried this:
Code: Select allsudo -i kwrite /usr/share/X11/xorg.conf.d/20-intel.conf
And I add the following in this file
Code: Select allSection "Device"

Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"

I've an asuspro (more precisely the p2520la version) notebook with the fn+f5, fn+f6 buttons that should change brightness of the screen. But they don't work. For volume it's ok (fn+f11/f12), and if I go in the system settings I c an change manually the brightness (I use kde so there is a bar with which change it). But when I'm outside and the screen brightness is low I found difficult to find the menu settings and the hardware buttons would be better.I've tried adding to the kernel the "acpi_osi=" command but doesn't work.
View 0 Replies View RelatedWhen I logout out of gnome, the brightness reaches maximum level. I've tried adding a script to adjust the directory "/sys/class/backlight/intel_ backlight/ brightness" to the rc.local file. I'm not sure if it has to do with my video card but it certainly could be the case since I'm using an experimental package for the Intel graphics card.
View 5 Replies View RelatedI have an issue with Debian 7.8 (wheezy) on my laptop. I've had to reinstall Debian on my laptop and since then I've had issues getting brightness controls to work properly.
It's a Core i3 370M processor with Ironlake graphics, I've had this issue before with Ubuntu and I sought [URL] ..... I've tried the steps that worked for Ubuntu (thinking they'd be the same as they're both Debian based) and it hasn't worked.
What should I try to get it to work? Since I have updated my grub config (as per the Ubuntu fix), brightness doesn't work at all and my screen now tiles ever so slightly when moving the cursor from side to side. I'll revert those changes if need be or if this issue cannot be resolved.
I've tried to install the Intel graphics drivers from 01.org, however I get an issue with libglib dependencies not being satisfied ( libglib2.0-0(>=2.37.3) ) that how to resolve.
i got an AOC 18" lcd, the instructions that came with it, are only for Windows and Macs, if i press a button at the base of it, a square appears with all the pictures to configure including brightness, but i can't click on the screen. The cd that came with the monitor, i assume only works with Windows/Mac, i haven't inserted it for fear of screwing up.
PS: when i pass the mouse over the square, the pointer disappears.
I have Lenovo ThinkPad X230 (model 23202TG) laptop. I can not control brightness via Fn-keys. Tested with default 3.16 kernel and 4.2.3 kernel from backports. After system startup brightness set to max and Fn-keys does not work but correctly detected by xev.Tried to add "acpi_backlight=vendor" to kernel boot parameters, as suggested at ThinkWiki but this does not work.
In the logs I found this messages

After some googling I tried to add acpi_osi="!Windows 2012" and acpi_backlight=native to grub kernel options but this also does not work. On other hand I can adjust brightness by echo-ing some value to sysfs.
Here is some information

I have installed kmilo, modprobed nvram and added line: KERNEL=="nvram", MODE="0666", GROUP="nvram" to 91-permissions.rules. I used command addgroup nvram and add me ( user tomasso ) to nvram group. Kmilo works fine but I am not able to change brightness of my laptop in kpowersave or by using fn key on my laptop keyboard. I am in powerdev group too.
View 2 Replies View RelatedI bought a new computer, pretty awesome machine, AMD FX6300 with a Radeon 260X graphics. Along I bought a new Led monitor AOC with DDC/CI capability.
It is my understanding that with the DDC/CI, monitors can have their brightness controlled just like laptop screens do, but better software controlled.
This is something I have done before with nvidia graphics, the open drive had the control and the proprietary only needed a small config setting. This was done however in a dekstop iMac, the screen also LED and HDMI.
So I just freshly installed debian jessie in this setup, it seems the open source driver does a pretty good job, but still missing the brightness control and audio through HDMI doesn't work either.
how to make brightness key work ?

Today I installed debian-8.1.0-amd64 on my older Samsung Laptop (Model r560). The installation without a desktop environment worked fine and the system booted without any problems into the virtual console. There was however one problem: when I was away from keyboard for some time, the screen turned black and when I came back and hit a button to wake the system up, the laptop immediately restarted. Later I installed the gnome desktop environment. This also worked fine.
But whenever I try to change the screen brightness in the gnome-shell, my system immediately restarts and successive attempts to boot debian fail. Some time later and after countless attempts to boot debian, it finally does boot again. By "debian fails to boot" i mean the following: The initial ram disk is loaded and fschk runs. Usually the system suddenly reboots at this point. SOmetimes, however, the video mode changes, the console font is changed and some services are getting started, but then at some point the system also restarts. I don't reach the point where a login prompt appears, or the graphical environment starts up.
Assuming, it has something to do with buggy acpi implementation of my hardware, I tried the following:
I tried to disable acpi completely by using the kernel parameter "acpi=off". This doesn't work and causes the kernel to hang
I tried to start debian without using a GUI using the single parameter. This also didn't work.
acpi_backlight=vendor also did not fix the problem.
After some experience with ubuntu i have just installed Debian Squeeze on a dell inspiron 1564.
I have faced with some problems:
1- The screen brightness doesn't change. neither the brightness hotkey works nor the brightness applet changes the brightness
2-There is no sound
I had none of these problems with ubuntu lucid.
Here is the output of lspci command:
When increasing or decreasing the screen brightness, Minecraft crashes and to an extent freezes my computer UI. What I mean by to an extent is that I can move the cursor around, but I can't click on anything. I can also run keyboard shortcuts and type, which is how I restore my system by terminating all java processes with pkill.
What causes minecraft to crash and how can I solve it?
