Ubuntu / Apple :: Screen Brightness On Aluminum 24 Inch Intel IMac
Sep 1, 2010Screen brightness on aluminium 24 inch Intel iMac
I was just about to re-install Ubuntu to dual boot with OS X on my 24 inch aluminium Intel iMac. Then I remembered the reason I got rid of Ubuntu the last time... screen brightness.
It is a known fault of these machines - the default brightness is set far too high. Sometimes it hurts the eyes. There is an application I have to use with OS X called 'shades'.
If I instal Ubuntu in VirtualBox I can still use 'shades', but when I run it natively as a dual-boot os, I do not have access to the 'shades' app so the screen is far too bright to use for any reasonable length of time.
Is there a workaround for this, without having to do something on every log-in?
(I am using the 64 bit AMD version of Ubuntu.)
Hardware :: Installing Radeon X600 On Ubuntu 10.04 LTS?
Apr 23, 2011I'm using a regular PC not Laptop with ATI Technologies Inc RV380 [Radeon X600 (PCIE)] and Ubuntu 10.04 TLS.
I want to use compiz, so I installed it from Ubuntu software manager, but it is not working. After I understood that it is because of the graphics adapter I downloaded the driver for Linux x86 from ATI's web, and when I tried to install the .run file I got this:
Quote:
Error: ./default_policy.sh does not support version
default:v2:i686:lib::none:2.6.32-31-generic; make sure that the version is being
correctly set by --iscurrentdistro
Removing temporary directory: fglrx-install.ipeBWr
Also I installed Catalyst and it said something like no adapters installed.
I read some threads around here and understood that Ati no more provides drivers for Ubuntu 10.04 for my adapter.

View 3 Replies View RelatedDebian Hardware :: Getting Lenny Working On Macbook / Can't Use Brightness Keys To Change Screen Brightness?
Feb 9, 2010I'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.
Hardware :: Decrease LCD Brightness - ATI Radeon
Feb 1, 2011I am running Arch on a Sony Vaio 64-bit computer with an ATI Mobility Radeon HD 4650 graphics card (xf86-video-ati installed).
I am attempting to decrease screen brightness; I have tried editing /proc/acpi/video/VGA/LCD/brightness (gives me: "write error: Invalid argument") and xbacklight -set <value> (gives me: "No outputs have backlight property").
Anyone know how I could decrease LCD brightness?
OpenSUSE Hardware :: Catalyst 10.8 With Mobility Radeon HD 2400 XT (iMac 20'')?

I did reboot that machine a couple times and switch the driver to reproduce the problem. It never occures with either radeon or radeonhd.
Ubuntu Multimedia :: Ati Radeon 9000 + 10.10 = Brightness?
Jan 23, 2011I have been just pretty much having fun with Ubuntu and a couple other distros for a couple years and have not yet ran into a problem like this. I'm pretty good in a command line environment although I end up googling syntax a lot b/c of that wonderful memory I have! Anyways..
I am running an older machine: P4P800 ASUS Mobo, P4 2 Ghz, 3G RAM and an ATI Radeon 9000.OS: Ubuntu 10.10 Maverick Meerkat Issues: Seems that anything that Compiz has to render the brightness is really low. CairoDock (w/ OpenGL) does not render like it does on other machines that I have, looks like garbage. I've come to the conclusion that I need to get a better video driver (Hope I'm correct here otherwise I've been going the wrong direction for awhile now).
Things I've tried through research around the net: I've attempted installing fglrx(command line style) from several tutorials I've found here and there. Most of them for older versions of Ubuntu and if I'm remembering right there have been a few significant changes lately, which may be causing my issues? Of course I've tried the easy ways: Installed all fglrx/ati/radeon related packages in Synaptics Package Manager
Checked System > Admin. > Additional Drivers before and after package installations
Ati Website - the drivers that they have are for XFree86. I don't think they can run on XOrg - it's a completely different setup? Again, I don't have a great understanding on how the back end of all this works, so bear with em.
I ran: echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf To disable KMS.
Rebooted - Video was much worse I then ran: echo options radeon modeset=1 > /etc/modprobe.d/radeon-kms.conf To re-enable KMS Rebooted again. Everything ran fine but I didn't have my Cairo Dock > which I can deal with, that's not why I'm posting.. Well, that's a good chunk of it - there's more but I don't remember most of it as I've been working at this on and off for weeks. Again, a lot of this was tried upon researching anything and everything I could find on the net - so some of it might sound ridiculous, I was just trying anything that would work!!

Debian Hardware :: Turn Off Screen On Imac G4
Apr 10, 2010I have Lenny installed on an Imac G4, running command line only. It's primary purpose will be SSH.
I would like to know how I can turn off the screen when I'm not using it. It will be left on running other things for periods of time, and I want to save power. (and the screen)
Since the screen is built-in, it might have a similar solution to what I would do with a laptop. On the other hand, there are no shortcut keys to dim the screen like on a laptop.
Because it is command line mode only, I will need to know what commands to use to dim or shut off the screen, or to configure an auto-off time limit.

View 4 Replies View RelatedFedora :: Screen Brightness Resetting Itself
May 23, 2010My issue is like this: I have a laptop (dell vostro 1400, NVidia 8400M video card) running Fedora 12 up to date. My desktop is KDE 4. I usually run the laptop connected to the power outlet, so my power profile is set to "performance". This power profile sets the screen brightness to the maximum. However, when I'm in the dark, I want to lower the screen brightness. The shortcut keys work, and the screen brightness is lowered. However, for some reason, after about 30 seconds it resets itself to the highest brightness setting. No matter how I set the brightness, it will always reset itself. Any ideas what can i do to correct this?

Mar 13, 2011Running F14 on Dell Studio 14 with LCD screen and US keyboard selected. After initial power on the keyboard selection of "Windows Key" + F4 will dim the screen and the "Windows Key" + F5 will brighten the screen. When being used, either combination will also show a meter on the screen to display the adjustment of the brightness. When the lid is closed the computer is set to suspend by default. After the computer is brought back from suspend the keyboard short cuts no longer control the brightness and the meter does not appear on the screen. I have not found any other way to control the brightness and I have to restart to get the keyboard short cuts to work again.

May 20, 2010I can't get the Ubuntu 10.4 Live CD for PPC to work on my old 800 MHz flat screen iMac G4. I believe it's supposed to work, but the installation dies with a magenta screen about a minute after selection of any boot option in the yaboot dialog.I tried all the sensible boot choices and options, all with the same result: some trundling of the CD reader, display of the messages related to the ramdisk, more trundling, then a blank magenta screen and no more trundling. The iMac becomes totally unresponsive: no more messages, can't enter any command shell. I get the impression (complicated story) that it begins to install the X server and then aborts.
This iMac has a PPC G4, 512 MB of working memory, and a GeForce2 MX video card with an nVIDIA chipset and 32 MB of video memory. There seems to be no hardware problem: OS-X 10.3 and OS-9 run just fine including wireless networking.

Mar 30, 2016I'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.
