I installed Ubuntu Natty on an Ideapad Z570. The screen brightness seems to be stuck. The keys that control brightness don't work and I can't find any option anywhere to change it.
View 1 RepliesAfter 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:
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 Install Ubuntu 9.10 and I can't control Brightness, show brightness popup (Fn+F5F6) but screen brightness don't work, I install NVIDIA Driver Linux-x86_64 version 190.53, modiffed xorg.conf.
View 9 Replies View RelatedI'm having trouble locating a way to adjust the screen brightness on fc10... It is only possible to use the monitor's control for now.Yeah my monitor make an annoying whining noise unless you turn it on 100% brightness, but that hurts my eyes.It is so crazy that they didn't put a brightness control in! ( or rather they destroyed working ones of year past, Why? )
View 4 Replies View RelatedI bought a Asus eeepc a few days ago which I really like, with the exception of one thing - windows 7 starter. I like Windows 7, but starter is just bad. I also really like ubuntu, so I've decided to put it on my netbook. I download the netbook edition from the site, put it on a usb drive, and than tested it out - well, my screen is dim, very dim. Changing the brightness setting on the tool bar up top doesn't change anything, and using the function keys does change it, but still keeps it very dim.
I've tried restarting my computer, same thing, I've tried messing around with settings in the battery options, nothing... I really don't want to install it if its going to be this dark, I can see things, but its not very pleasant to use. I'm starting to consider that its the problem with the file I downloaded. Theres nothing wrong with my netbook, everything worked perfectly fine in Windows 7. I use the full version of ubuntu 10.04 on my other laptop which works perfectly fine, I'm not sure why this version is acting so weird on my netbook.
I ran Kubuntu 10.4 from the Live CD and from the start The screen was automatically set to be as dim as possible, but in the power manager the brightness is set to be as bright as possible. Moving around the slider doesn't do nothing, and when I click the battery icon in the tray, it shows another brightness slider that's set to dim as possible, when I move it around it has no effect and just goes back to where it was when I close the popup window. Right now I'm running from the livedisk on an IBM T42 thinkpad laptop.How do I fix this, is it a hardware issue, I've had problems with my graphics card in the past with compositing in X/Ubuntu.I've found some text files for the backlight, they're all set to 0 which I believe is the problem, however even though I'm running the File Manager as root with kdesudo and the permissions are set to read and write for the owner, who is root, I can't save any changes.
View 2 Replies View RelatedI'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 had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?
View 1 Replies View RelatedI am using Ubuntu linux, and I want fn + up key and fn + down key to change the brightness instead on fn + F4 and fn + F5. I've tried looking for something in the Keyboard Shortcuts menu, but there is no command or key specified to do that. I could make a custom key shortcut, but I can't find the command to change the brightness. Is there a way to make another key do this? My laptop is a Dell Inspiron 1545.
View 10 Replies View RelatedJust installed on my netbook the latest version of ubuntu (10.04). Have seen a few issues with other users however they have seemed to be able to make fixes.My problems are:
- Screen half brightness no change (does anyone have a fix yet?)
- Wifi not working (tried updating kernels, says they're the latest)
- Multi touch not able to be enabled, (again have seen a fix but for some reason won't work)
I installed Ubuntu 10.10 on my laptop and encountered several issues.
1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.
2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.
3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.
4. The screen is black after suspend.
5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:
[Code].....
I added the Brightness Applet to the top panel, but when I change the brightness, nothing happens. D:I can't stand this, it's like my screen is stuck on supa-bright and it's hurting my eyes. When I load my PC up in Windows, the brightness control works just fine. But it doesn't seem to work on Ubuntu.
View 9 Replies View RelatedI want to set fn + Up or Down Arrow to change the brightness of the screen, instead of fn + F4 and F5. However, I don't know the command to do that, and I can't find it in Keyboard Shortcuts.I've seen something about editing a file in /var, but that requires root permissions.
View 9 Replies View Relatedi use a HP Pavilion dv6-3016ax everything works perfectly and i am very happy with ubuntu! If i could get the Brightness keys to work and the microphone i'd be even better. The brightness FN keys change the slider but make no physical difference of the brightness. And the microphone just doesn't work.

View 1 Replies View RelatedRecently, I installed Fedora 15 in my Sony VAIO Laptop Series E. Firstly, I had a little problem with nvidia drivers and wireless because I installed from a normal CD, but then I repaired it installing drivers from the web page and updating the system. However, I continue having a problem with changing brightness even with the Fn buttons or with the gnome configuration control. I followed some suggestions as for example these ones http://forums.fedoraforum.org/showthread.php?t=262545, but nothing change. I already tried with xbacklight but still not working. I also did a change in grub conf file (following google search suggestions) adding these commands: acpi_backlight=vendor acpi_osi=Linux, but nothing.

It was working just fine on the previous version of ubuntu.
My computer (Samsung R580 N330M)seems doesnot adjust brightness both power manager and configuration file in /proc, I tried NVIDIA setting and it works,but I think it changes the color,not LCD. is it caused by driver problems?

View 5 Replies View RelatedI'm a fairly nocturnal creature by nature, but life requires me to spend more time during the bright hours of day. I also have a visual impairment which makes it that my eyes take a very long time to adjust to darker situations. I need to be able to easily dim my screen so that using my computer doesn't keep me awake as much and doesn't prevent me from doing other stuff.
I will accept both a hotkey based solution "like on most laptop" as a timed one. My main monitor lacks simple brightness/contrast controls. f.lux doesn't suit my needs, since it only changes the screen's color temperature. I'd like the solution to work regardless of the make and model of the video card involved. Wearing sunglasses is impractical, since they make it hard to interact with objects around my computer.
accidentally I raised my brightness to 100% so I couldn't see anything..My battery died before I could fix it with tab or something else.now I can't fix it because I can't see anything.Is there a way to adjust color brightness through my unix terminal.....?
View 5 Replies View RelatedMy laptop with Ubuntu 9.10 just randomly while adjusting the brightness using the shortcut key commands on my laptop the brightness started to glitch between two brightness levels. If I don't use the shortcut keys it doesn't glitch unless I shut the screen or restart the computer. So I've had to put up with this for the past couple months now and I think that it might even drive me to reinstall but then I lose all my data.

View 6 Replies View RelatedSometimes, out of the blue, my screen will suddenly change brightness. And no, not the gnome power manager dimming the screen when idle, I'm talking about it suddenly going from dimmest to brightest when I haven't even touched the screen brightness buttons in the last few minutes.
what package would I file this bug against)? This is Maverick on a thinkpad T60, and I can provide any other information that people find relevant. On what may be a related note, it seems that one push of the screen brightness up or down buttons causes two increments in brightness.
I originally installed Maverick on my Macbook 5.1 using rEFIt to dual boot. For some reason, after installing Compiz my screen brightness functionality stopped working. It was permanently 100%. I thought that upgrading to Natty might work, but no luck. So far I've tried changing the brightness manually in terminal and in power-management, editing the grub file and also reinstalling compiz, all to no avail. Trying to alter brightness using the fn keys displays the brightness panel in the top right, and it decreases in value as it should, but the screen stays bright. The brightness settings work fine when I boot to Mac.
View 9 Replies View Relatedon my fairly new ubuntu install (10.04.1 LTS) on a laptop, the screen brightness changes seemingly at random, i.e. while I do other things like surf the web. Often, the brightness will decrease some (it does not fade to black as reported by others with similar problems) and come back a few seconds later
