Ubuntu / Apple :: MacBook Pro 5,1 Backlight Keys Do Not Work
Mar 27, 2010
I am dual-booting Karmic/OS X. I have a MacBook Pro 5,1. When using the keyboard to change the backlight, the graphic in the top left does move to indicate a higher brightness (albeit, it moves extremely slowly).
I, of course, have all the necessary drivers installed.
I have all the packages I needed from the Mactel repository. This has been a problem within Karmic since I've put it on my MBP. There have been several updates from the Mactel repository concerning the Nvidia backlight package (I don't remember exactly what that package is called though). I hope each time that it will fix what is going on, but obviously, it hasn't.
Is there any program that I could use to otherwise change the backlight? When I'm sitting outside it's really difficult to see what's on my screen as it also doesn't automatically respond to the change in environmental brightness by making the screen brighter.
Just upgraded to 10.04. Everything seems to still work on my Macbook, with a bonus being the buttons to modify the keyboard backlight brightness seem to work now.
However, the only caveat is that I can't seem to turn off the backlight. Pressing the dim button all the way to off just seems to reset to full brightness. Even if I set the brightness to 1 (almost off), the backlight seems to reset itself to full brightness at seemingly random times.
Running this command used to turn it off, but now doesn't work:
Code: echo 0 | sudo tee -a /sys/class/leds/smc::kbd_backlight/brightness
Is this a bug? How do I turn off the keyboard backlight?
Neither Ubuntu's Unity or KDE respond to the function keys on a regular Apple USB keyboard. I can plug in a non-Apple keyboard and they work just fine. What needs to be changed or configure so that F1 and company on the Apple keyboard work as on other keyboards?
I've recently installed Ubuntu 10.04 (amd64) on my MacBook 3,1 (1GB memory). Most things work perfectly on install, and I've got the iSight working now too!
However, although suspend works fine, hibernate does not. When I try to hibernate, the screen goes blank with the back light on for a few seconds, then the screen goes off completely for about 0.1 of a scond and I hear the optical drive whirr (like it does when booting), and then about 4 or 5 seconds after that it finally powers off.
Then, when I restart, I see the rEFIt menu, then the GRUB menu and it appears to boot like normal and *not* resume from hibernate!
I'm not sure what log I should look in? When I look in /var/log/pm-suspend.log the last line says "performing hibernate", but there's nothing about even attempting to resume.
UPDATE: Forgot to mention, I have a swap partition that is larger than 1GB.
UPDATE 2: Also, after attempting to hibernate, when the system restarts, WiFi has been disabled -- I have to double-tap (right-click) on the WiFi icon and re-enable it. I *think* this is because the hibernate process disables networking, but it then fails to re-enable it because is fails to resume.
I've been using Ubuntu 10.10 64-bit on my MacBook Pro 5,5 for about a week now. And I've noticed that the screen brightness adjustment does not work. When I click the F1 and F2 buttons I get the notification that it's changing but it doesn't actually change it. So I added the brightness adjustment to the panel and it won't let me move the toggle thingy. Has anybody else had this problem? All my other F keys work fine.
I'm having a problem getting the apple remote on my Macbook 2,1 to work with Karmic and am looking for a little advice. I have followed the guide here [URl] and utilised the extended .lircrc in the first post of this thread [URL]linked to by the guide however I cannot get any action from my remote (it does work in OSX).
The problem, I believe, lies in where Gnome needs to start irexec and irxevent. Running irexrc -d from a terminal gives no output but I can also not find a process running after launch.Running irxevent -d returns 'irxevent: could not connect to socket irxevent: No such file or directory'I have also installed gnome-lirc-properties which (until a recent reboot) reported that there was no IR daemon running.
I can't seem to get any of the alt-keys from my regular keys. (i.e. alt+(any key) does not give me the output that it normally should. For instance, I can't make the "does not equal" sign by pressing alt+= (alt+equal sign))Is there any way to enable all the keys in the MBP keyboard? Or am I just stuck without my dear alt-keys?
I have an Asus K50IJ running Fedora(which I love as it fixed my sound problems). When I first log in, I can press the brightness keys and it responds immediately for 4-5 keypresses. After that, it has a ~10 second delay between me pressing the key and the computer responding. When using acpi_listen, it displayed that it recognizes the event long after I press the key. This is a pretty minor issue, but very annoying. Here's some possibly-relevant output from dmesg:
I've finished integrating proper keyboard backlight support into gnome-power-manager (which in turn uses upower to actually control the keyboard backlight) which with any luck will be available in Natty out of the box. A similar patch should also land upstream too so Fedora etc should get it for free too in their next release too. In essence this allows us to provide the user with greater feedback and control than say just using pommed (ie. we can dim the keyboard on idle like the lcd display etc, and can display nice notifications of the keyboard backlight level too - see attached screenshot).
I have a late 2009 MacBook, white, unibody, and I wish for the F1-F12 function keys to have their primary role as F1-F12 keys, but allow me to use them as media/volume/brightness keys as a secondary role, when the "fn" key is held down at the same time as corresponding key.
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?
I don't care if this is done in the bios or a kernel module or software. Is there any way at all to do make the 'fn' key act as 'control' and the 'control' key act as 'fn' in linux running on a macbook pro?
PS. You can do this with software in OSX with the application KeyRemap4MacBook.
I've got a Macbook Air and a verified 9.10 liveCD in the external superdrive. I can successfully boot to the CD, but when I choose "try ubuntu without installing", all I get is a blinking cursor in the upper-left of the screen forever. Any idea why it won't start? CD works fine on my Dell, that's why I say it's verified.
Today i went ahead and installed ubuntu on my windows desktop pc. I tryed the live cd and tested it out and everything was fine i then installed it using wubi. I then wanted to install it to my macbook ( bought in june 2009 ) and i booted the live cd and chose try ubuntu without any change to your computer. It booted a black screen with a white _ at the top then the screen went white and did nothing. I tryed it several times and nothing happend. I then said ok il maybe just try install it through wubi on my bootcamp partition and it all went fine until i got to the windows bootloader and chose ubuntu, it camp up finishing linux installation and where its meant to change and show the ubuntu symbol after ( i know because i've installed ubuntu on the pc) the screen went white. Nothing.
I have a first generation Macbook that shipped with Tiger. I don't often use the os x partition anymore, as I installed Windows XP on a 15 gig partition back when bootcamp was still in beta and I normally use that when I'm on my laptop. Since Tiger is rather old and the only reason I would want to upgrade to leopard is to have access to bootcamp again (they disabled access to the bootcamp application in os x, but I can still boot into windows), I have been thinking about wiping out my os x installation and using ubuntu instead. Does anyone have any thoughts on the pros and cons of totally removing os x?
The main reason I hesitate to just jump in and do it is because if I decide to install os x again I won't be able to install bootcamp again, unless I buy leopard. If I wipe out os x and install ubuntu, will I still be able to access windows in the same way? Windows uses bootcamp drivers to run properly, so I have never quite been sure if it is pulling something off of the os x partition or if it is totally standalone.
I have just installed the latest Ubuntu 10.4 LTS on my Macbook Pro and the one thing I cannot get to work no matter how much i try the fixes and suggestions they do not work. I have the volume controls, even the ones on the keyboard work but there is just no audio what so ever.
I get through the install just fine till the end Iv tryed twice. When i get to the "Who Am I" screen i fill out all the info the "Forward" Button doesn't light up, it keeps on installing till "Ready when you are" and then i'm kinda stuck.. I can go back to past screens and edit the info and stuff but thats it can't move on.
When I installed I noticed no sound was emanating from my computer and a red light coming out the headphone jack. s there any reason why there wouldn't be any working sound? Everything else seems to be working fine. I installed the additional drivers but the only ones listed were graphics and wireless.
Introduction: I wrote a very extensive and quantified tutorial and informational guide aiming to upgrade the latent information from the wiki's on MacBook Pro 5,2. An accidental toe tap ended with me bumping my head and pressing the X button on firefox. What happen had to be 1 out of a billionth of a chance. So this version will be simple and to the point, until I can muster enough patience to detail it all out again. Please correct any errors.
sudo apt-get install pommed - To get backlight keyboard working. sudo apt-get install cheese - To get iSight working. sudo apt-get install lirc - to get remote working (tested in XBMC) sudo apt-get install bluemon - Pairs Mighty Mouse and Wireless Keyboard (optional)
I have installed it on my Macbook Pro 5.5 via rEFIt+ and the install works well except for the lack of sound. I've seen this issue posted about on the forums and I've followed the advice posted here as best I can with my limited knowledge. Terminal didn't recognise the aptitude (command not found). I guess that may be due to an older build of Ubuntu being used in the example?
I have downloaded the 64 bit iso and burned the CD-ROM per the instructions. The CD is verified. When I boot the mac, holding down the C key, I get a menu of options relating to Ubuntu. If I choose the trial run from CD then the CD drive starts up but the screen goes blank and I end up with just a blinking underline cursor in the upper left hand corner of the screen. Does anyone known if one can, and if so how, to boot the live CD on a Macbook Pro 5,2?
The wiki says there is a way to install from usb but I can't get it to work on my Macbook Air 3,2 (the Nov 2010 revision, not the one from last week).
My goal is to dual-boot OS X and Ubuntu, but I can't get the Ubuntu installer to boot. I've tried a lot of variations on the instructions I've found, so I get the feeling I'm probably missing something fundamental.
I installed refit and used BootCamp to partition the drive. I downloaded desktop/alternate and i386/amd64 isos. I tried to follow the instructions to use unetbootin on OS X to install the ISOs to my USB drive, but neither drive that I connect appears in the "Drive:" selector when on OS X. I used usb-creator-gtk and unetbootin on an Unbuntu machine to try each of the four ISOs.
When I try to boot the Air from the USB drive, I got a few different types of failure:
gpt, single fat partition, unetbootin -> alternate amd64 result: "Non-system disk" "Press any key to reboot" mbr, single fat, unetbootin -> alternate amd64 result: black screen, fan runs at 100% after a minute or two
I tried dd'ing a disk image to my new partition as described here and here with the desktop amd64 and i386 images, got a few different errors - once syslinux complaining "Error: No configuration file found" when the drive I dd'd from wasn't properly unmounted before bringing it to the Air, once I chose the drive in refit, refit displayed the single logo, and it never booted, and once I got an error I didn't copy down about needing a boot floppy.
Has anyone successfully booted Ubuntu from USB key on the Air? Exactly how did you prepare which image?
I've been trying to install 11.04 on my MacBook Pro for the past couple weeks, and I'm getting pretty frustrated with it. When I try to boot from a DVD, I either get a blank screen with just a flashing cursor, or it will ask me if I want to try, install, or verify the disc, after which I will get a bunch of different-colored blocks all around the screen.
I have installed past versions of Ubuntu on this computer with no problems, so I'm pretty stumped now on why I'm having this problem. Also, I've tried the Ubuntu Wiki and sticky thread on this forum, but nothing in either seems to help. Additionally, I have installed Mac OS X 10.7 Lion. I don't think it'd effect anything, but I thought it was worth mentioning.
I recently bought a macbook pro 5,5 (unibody) and I'm running both OSX and Ubuntu 9.10. I love the laptop, but I've been having some issues with the touchpad in karmic.
In OSX, I can keep my thumb on the bottom of the touchpad as if it were a button and operate the rest of the touchpad as normal. With my thumb on the bottom of the pad, I can still click and drag and use two finger scrolling.
In ubuntu, I've used the instructions from[url]
If I have a thumb on the touchpad, it always assumes I'm two-finger scrolling. I've tried synclient BottomEdge=600, but it doesn't make any difference.
