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 writing a script to toggle LCD backlight on my laptop between minimum and previous/current level. I will then assign this script to a button. For this I need to be able to adjust backlight by using some command line utility. Also, this must be possible to be performed by a regular user.
What I have already tried:
1) The "xbacklight" utility. This didn't work. Program reported something like "no outputs found".
2) Used "acpitool -l <backlight_level>". This didn't work either.
3) The "echo -n 100 > /proc/acpi/video/VGA/LCD/brightness" works only when I am root. Changing permission of the file to allow writes by a user only valid until reboot. After reboot I need to change permission again, so this approach is not good either.
What works on my laptop, but with GUI:
1) Adjusting LCD brightness in "System->Preferences->Power Management" works.
2) Adjusting brightness with Gnome Brightness Applet works. However, after changing brightness with applet it says "Cannot get laptop panel brightness" and shows red crossed circle icon. Even after applet shows this message, it is possible to change the backlight level. It seems like the brightness level cannot be retrieved by the applet/system, but it can be set.
I can see that it is definitely possible to adjust LCD brightness through software because of the 2 things above, but how do I allow any user to change it from command line?
So, what are my other possible choices for changing backlight from command line?
I have an Asus P50IJ-X2 and in lucid the backlight cannot be adjusted. The panel app doesnt work, when I click on it and try to adjust the slider it just disappears. When I reopen it the slider is at the top left corner of the screen.
The function keys seem to be detected alright, but when I press them I get the notification that the brightness is going down but nothing happens. Also after the first press the notification gets extremely laggy. If I press the brightness keys again it takes 30 seconds or more for the notification to show up. Also after the first press my volume function keys have the same behaviour in the notification area as the function keys.
Also messing with the controls in the power settings doesn't do anything. The strange thing is all of this worked perfectly in Karmic. The function keys, auto dimming, everything just worked out of the box. I have no idea where to start trouble shooting this so can anyone give me some direction?

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/

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 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.
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?

Totem didn't play .avi movies by default after my new CentOS 5.3 install. In my effort to find a way to fix it I learned in another forum that installing VLC allows almost all video formats to be played. So I added RPMForge to my repository group then I found and installed VLC with no problem.
Now that VLC is installed and I've had a chance to use it, I've learned that it fails to save my brightness setting between launches. This is very frustrating because the default brightness is always too dark, which means I have to go to the controls and reset it every time I launch the software. Does anyone here know how I can save my brightness setting between launches?
I just finished installing Fedora 11 and I'd love to love it but the issue is I can't see the screen without straining my eyes. So I bring to you almighty support forum a challenge: Need to enable the screen backlight. The laptop model is an Asus G50-X5

View 1 Replies View RelatedMy recently installed OS, keeps on displaying a GRUB menu instead of the normal screen and has an option of normal start up or ( I forgot what it's called but some sort of .. ) Fixing Option. It has worked before but yesterday the error wouldn't stop coming up after it randomly crashed while the computer was working. I haven't tried it again today, but will do soon. The first option of normal boot up said something like 0x01002 is in use and didn't load.
The second one occasionly came up with an option for normal boot after it had 'Fixed' it. But most times it would come up with some terminal like dialogue, then stop and not load, don't know if it crashed or what ? Hope this is enough information for you, but as I'm only 12, I don't have a clue what to do, except the obvious option of rebooting again and again.

Always the same error when booting. After a period of time, (Graphical User Interface) the mouse click no longer operates, also text input isn't possible.
I had no access to the system at all, even crt alt F1 stopped working, also text input was no't possible. so reinstall was the only option. Maybe there is a connection with this two errors.
I've reinstalled Debian 8 several times. Still, both errors stay.
The same happend again (in the GUI) is nothing possible, no txt input, no mouse click), but now I have access to the system, ctr/alt F1 is working.
After regular upgrade (I am using Unstable) I boot my system today but failed to load X using xinit (which I always use). Using startx X loads but leaves it unusable, both mouse and keyboard don't work (I never use startx really as regular user but in root). The message is:

In my /etc/X11/Xwrapper.config I changed "allowed_users=console" to "allowed_users=anybody" and that doesn't work.

I installed linux-image-4.1.0-trunk, when I boot into the kernel there's no wireless available. Dmesg indicates seems like the firmware is loaded, although firmware-iwlwifi is installed:
...

Built a machine w/ i5-4440 & gtx 960. I installed xserver-xorg-video-intel & xserver-xorg-video-nouveau. Xorg -configure fails, so I added xorg.conf I found online, makes no difference. xrandr can't open display. startx of course fails.
Backstory: My plan was to dual boot sid + stable as fallback with shared partition. First installed stable and whether connected to mobo or gfx card, I couldn't get login on tty, it would just hang on errors. So I installed sid (this time using lvm to hopefully make partitioning easier) and while I get the "failed to load nouveau" errors on mobo, gfx card gives me a login screen.

The problem: backlight is in maximum state and I can not change it.
There are a tons of advices like this:
1 - Open terminal (as a superuser) and type: gksudo gedit /etc/default/grub
2 - In the text file that opens, find the line which says GRUB_CMDLINE_LINUX="" and, inbetween the "", insert the words "acpi_backlight=vendor" (the line will be as follows: GRUB_CMDLINE_LINUX="acpi_backlight=vendor"), save and close the file.
3 - Back again in the terminal session, type: sudo update-grub
4 - Reboot.
It does not work...
I have been running Squeeze for quite a while on my Asus W5F laptop, and recently I have started having intermittent issues with it not starting the backlight after returning from suspend/sleep. Most of the time, the screen comes on as it is supposed to, but once in a while the computer resumes but the backlight is off. It is not just turned down to the lowest brightness setting, it is all the way off. I can read the screen only if I take a flashlight and shine it on the screen and look very closely. Most of the time, it is just easier to go to another machine and use ssh to restart.
I'm not familiar with how the suspend/resume process works, so I don't really know where to look for configuration options. It seems like there are a number of different places, but how they work together, I don't know....
Neither the keyboard brightness adjustment nor echoing values to /proc/acpi/video/VGA/LCDD/brightness have any effect, though these do work to change the brightness when the backlight is on.
I took a look in /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux, which shows the following options.
[ "$HAL_PROP_POWER_MANAGEMENT_QUIRK_S3_BIOS" = "true" ] && QUIRKS="$QUIRKS --quirk-s3-bios"
[ "$HAL_PROP_POWER_MANAGEMENT_QUIRK_S3_MODE" = "true" ] && QUIRKS="$QUIRKS --quirk-s3-mode"

The laptop is several years old and has had the lcd display replaced a year or two ago. It is possible that it is a hardware failure, but I lean away from that because a restart always brings the screen up fine, as does closing and opening the lid (which blacks the screen, no suspend).
I am in serious situation involving PPTP protocol VPN in Debian 8 Jessie stable. I recently became a paid VPN subscriber. Using PPTP; Is there a way to automatically route all traffic through ppp0? Im getting the vpn service killed (ip address goes back to normal unmasked state) whenever there is a power outage (modem reset) and there are alot of those where I live, Im going to get astabilizer and I need a software solution for the situation as well. Theres gotta be a way to route all traffic through the VPN route ppp0 . I tried adding persist and maxfail 0 to the pptp config file but it did not do what i wanted.
Here's my peer configuration file :
pty "pptp blabla.net --nolaunchpppd"
name blablabla
password blablabla
remotename PPTP
file /etc/ppp/options.pptp
require-mppe-128
refuse-eap noauth
persist
maxfail 0
On a second note, its clear to add that I basically need a way to also auto load the line
pppd call blabla.net
and
route add default dev ppp0
On system startup by default so the computer does not use "Wired" connection ^at all^ when not through ppp0. Any other way of not losing VPN anonymity ever due to hardware malfunction.
Is there a way to do this? Ive looked on the net and everything seems like its either from the nineties or can fry my pc , Im no debian expert, less than a year at linux..
Need it to use wired only if ppp0 is being used so if its no vpn, no connection at all period,
