Ubuntu / Apple :: Keyboar And Mouse Not Working After Install On Intel Imac?
Jul 21, 2010
After booting up from the cd, I noticed that neither my wireless keyboard or wireless mouse were working. after a while a different screen came up that allowed me to use my keyboard arrows to choose "try ubuntu without affecting your system". So I choose that option and got to the desk top but then i had no use of the mouse or the keyboard at all. I then ejected the disc by quickly pushing the power button in the back of the iMAC and once the disk was out was able to restart the computer.Now i am in a black screen that says that there is no bootable drive.I know about the option key at start up, but that is apparently not working because my keyboard is not being recognized

Yesterday I've try to reinstall ubuntu on my iMac at the only difference is that I don't want to see mac OS any more as I never use it.
So I erase all partitions of the hard drive (including the EFI one)
set the HD as GPT and use the following partitions schema:
Then I install ubuntu 10.4 TLS. every thing went well up to the end where is told me installation successful and ask to restart.
But when I restart it give me this: e745...(cut)...0a2 end_request: I/O error, dev sr0, sector
I know that my iMac doesn't use a BIOS but an open firmware and I didn't create any EFI partition.
should I create one? do I have to modify something in the Open Firmware? and it it possible to install Linux ALONE on an iMac (intel)? as I don't want macOs on it nor rEFIt as possible.

in an attempt to demonstrate just how compatible our college Macs are (please hold the tomatoes) I'm trying to install Ubuntu Karmic alongside Mac OS X Leopard and Windows XP Pro SP2. The problem is, I hold down 'C' to boot from the CD, and all I get is a black screen with a flashing DOS-style cursor. If I boot it without holding C, it works just fine, booting into either Mac or Windows (whichever I specified).This is understandably irritating, and I'm trying to figure out the source of the problem.

Screen 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.)

I have sound using my headphone without any trick but my internal speakers don't work.
Do some manage to make them work on an iMac 27" i7 and Lucid Lynx?

I'm not sure if I have a hardware or OS problem. Firewire on my old G3 iMac has stopped working. Previously I've used a scanner and an external hard drive (Iomega eGo) without problems while running Lucid. Now neither works with the iMac, though they both work when connected to a PC. Both the PC and the iMac are running the latest versions of Lucid.
I can't tell when the problem began since I don't use the scanner or hard drive that often. I did try booting using the live 10.04 CD for PowerPC and had no joy with either device.The LCD on the hard drive lights when connected to the firewire port so power is coming through. The scanner has its own power supply.Checking with lsmod I see that both the modules ieee1394 and ohci1394 are loaded.I suspect it's a problem with the hardware. Does any one have an idea how I can go about verifying that? I'd hate to bin an old faithful without first checking everything out.

I'm making some tests with the internal microphone and I've managed to record sounds but the results have a very low volume. I mean, I have to put the input volume to the max and I still get a pretty bad result. I've checked too the input volume in the alsamixer but no way, can't get better results.

When I first had partitioned, and formatted appropriately, I installed the newest version of Ubuntu available (Time of posting 10.4), on the partition made with bootcamp, rebooted into Linux with rEFIt Now once I booted into 10.4 I got to the desktop, it started asking me about restricted hardware drivers, so I went into System > Administration > Hardware Drivers, It then searched for the drivers, it found the STA driver, and the B43 driver, I am unable to allow both. So I went on to try ndiswrapper, I downloaded it off another pc, compiled and installed on the iMac. then I got the driver off the Leopard install disk, put that on my flash drive, extracted the files from the installer, put that on the flash drive, then I went back over to the machine in question, copied the file to the desktop, I used the cd command to navigate to the folder, then ran ndiswrapper -i bmcwl6.inf, I made sure that the inf and sys files were in there, so I didn't know what was going on exactly.
So then I went into the software sources, and enabled the cd as a software source, then went into Synaptic, and installed the drivers, it said the install was successful, however when I go back to enable it, will still refuse to activate, I have looked all around for solutions, I have even checked out other threads on this matter. The funny thing seems to be, is that everyone, or almost everyone who has this card on their computer, are upgrading to 10.04, when it worked on a previous version.

I run lucid lynx 10.04 beta (live) on an iMac G4 800MHz flat screen. How do I partionate an 80GB HDD?
In gparted I see 8 very smal partition exept the hfs+ partition. I have thrinked the hfs+ partition and made a 1GB swap, approx 50GB /home and 5GB /.
When I try to install Ubuntu say I need a new world partion for the boatloader. How fix it? first it say I need 8MB, then 1.8GB!
Is it 'newworld' or 'New world start partition' and what should bee the mount-point?

I remembered about my old iMac G3 and currently had OSX 10.2.8 installed on it but its too old to support flash so no ..... or anything (why I stopped using it) I do remember gnash working on it along time ago when I had Ubuntu 4.10 installed, gnash is just really glitchy but that was quite a long time ago I used it so I'm only assuming they have made some updates as Ubuntu progressed.
I tried have now tried 4.10, 6.04, 6.10, 7.10, 8.04, 8.10, and 10.10 all for ppc using the alternate installer cause the desktop installer just makes the iMac restart when I tried it with 8.04 I think it was so I just stuck with the alternate installer method and EVERY one of those versions of Ubuntu fails to install the base system..
I don't know what it is or why this is happening because that is the same disc I used before with 4.10 and it now cant find a file, I tried re downloading 4.10 and burnt it again on my dads laptop (Toshiba Satellite with Ubuntu 10.10) at 8x on a CD (the iMac has a CD ROM only). I can't figure out what to do, I just downloaded the Desktop installer for 10.04 and the alternate installer for 10.04 as well and I'm going to burn both of those and see what happens.
Every install I tried to do I did a full whip to the hard drive so its a fresh install of ubuntu only. I thought maybe something was wrong with the hard drive now so I tried 10.2.4 again and it installed fine and wanted me to update to 10.2.8 again so I turned it off and tried 10.10 again and nothing is working. It's going on a week soon I've been messing with this old computer trying to get it working and everything is failing on me

I installed Lucid PPC on a G4 iMac (lamp-style, 800 mhz) using the netinstall mini cd. The install environment booted and installed a base system without any problems. However, when trying to boot into the installed system, I get about a second of text after the yaboot screen, then darkness, then a full screen of bright red. Note that X is not installed, so the red screen is not an xorg problem. I've tried booting with "Linux nosplash video=ofonly", and "Linux single" but the problem occurs in both cases. I can use rescue mode on the cd and chroot into my system on the hard drive, but I'm not sure what steps to take from that point. It does seem to be a functional system when I'm chrooted, I can use apt etc.I don't want to give up on this installation and install karmic yet,

I have Karmic Koala 9.10 working (near) perfectly on my iMac7,1, as identified by
Code:
NOTE: See below for Lucid 10.04 update to these instructions
IMPORTANT: You need to complete the installation procedure while connected to internet via the WIRED network. Then you can enable the wireless by installing the restricted drivers, after the install is complete. Also the fglrx ATI Video driver is effortlessly installed via Menu > System > Administration > Hardware Drivers
The sound card gave me some trouble, as it is an Intel HDA Model, reported as 'Codec: Realtek ALC889A' by
Code:
It shows up in lspci as:

It sounded rather tinny at first, when I tried mbp3 and other model names. Then I added the following line to /etc/modprobe.d/alsa-base.conf :
Code:
After reboot, my sound is full and can be put much louder than before. Jack detection works. Some people might have to leave out the power saving options. See below.
dmesg reports:

Sources consulted are mostly the kernel documentation ( Enter into the terminal: sudo apt-get install linux-doc
The relevant info can be found in HD-Audio-Models.txt.gz and HD-Audio.txt.gz in /usr/share/doc/linux-doc/sound/alsa )

I have Ubuntu 10.04 installed in dual boot with Mac OS X and it did work properly for a while. But after installation of ssh, gdesklets and perhaps some other general software, the mouse and keyboard stopped working.
As I restart the computer and start ubuntu normally it proceeds to the login screen, but the mouse and keyboard are not working there. Pressing Power-off button on the computer box brings up the count-down menu and it switches off in 60 seconds.
An attempt to use the rescue mode or the older release (from 2.6.32-22 to 2.6.32-21 - the only ones I have) leads to the same results (in the rescue mode the power button does nothing though).
Mac OS works alright (I'm using rEFIt boot manager).

I just installed the latest version of Ubuntu on my intel-based iMac with OSX 10.6 (Snow Leopard), but I don't know how to bring it up.
I partinioned my hard drive for it. I inserted the CD and pressed C when restarting my computer for it to come up, then I installed it on the partition. It was done installing and said the computer must restart now, so I pressed OK. I got a black screen with a bunch of white text saying something about an error. It was pretty much "frozen" (I didn't know how to get off the screen), so I turned off the power manually by pressing the power button. I turned the power back on, but I get no option for Linux. I tried putting the CD back in, and it boots from the CD but it's still the non-installed version. So I thought maybe it didn't install, so I pressed install again. It said to choose where to install it, but my partition of free space said Ubuntu was already installed on it.
I'm really confused and don't know how to get it to start up when I turn on my computer.
EDIT: Here's some more info about my mac incase you need it:
iMac
OSX 10.6 Snow Leopard
Intel
4 Gb of RAM
250 Gb hard drive (29 Gb partitioned for Linux)

I decided as ubuntu 10.10 was so good on my old laptop i would install it on my old G4 iMac 17" LCD.
However, All I ever get is a black screen.
i tried the alternate install and it all seemed fine until it reboots and.... Black screen!
I burned the ubuntu 10.10 desktop ppc cdrom nice and slow, checked MD5 sums and verified disk etc...
I put it in the cd tray booted up, and let it start the lice cd... For a split second I saw the ubuntu loadscreen before it disappeared in a hiss of static and went to a.... Black screen.
I've tried alt-command F2, but don�t get a console
i am at a loss as to what to do next. I partitioned the whole HDD for ubuntu during the alternate istall. So until i can get Ubuntu up and running, I have a very heavy paperweight.

my partner and I have been trying to wipe the mac os 9.2.2 (UK version) and replace with ubuntu 7.04 (previous forums have mentioned this is the most stable version of ubuntu for the G3).
We bought this iMac G3 the other day, cheap, for our sons room... homework, research, music etc. He's used to the windows system that the Mac os looks both boring and confusing to him. so we thought we'd go in between and use the ubuntu os.
Any who! downloaded the iso for ubuntu 7.04, burned the iso image, alternate cd install of course. the only problem we are having is getting the disc to boot at start up on the iMac. (cd rom doesn't have a tray, I've seen this question asked before). the cd burned fine, the disc works on other systems. but when it comes to boot up on the iMac, nothing happens. press and hold down c, cd drive turns the discs a few times then carries on with the original mac os 9 start up.

I can't install any flavour of Ubuntu 9.10 onto my new iMac G3. Here are its specs:
iMac G3 New World (Indigo)
350MHz G3 Processor
192MB RAM
6GB Hard Drive
Slot Loader (CD only - not DVD)
Mac OS 10.3 Panther
The drive does work - I've played music from CDs on it, and it does allow me to view PDF files stored on data CDs. I can even view the Ubuntu CD through the Finder on the desktop. It just really doesn't want to boot from the CD.
I've tried multiple Linux distributions (all of them PPC compatible).

I want to install Ubuntu on a PPC iMac.It is running 10.2.8.I'm looking for a ppc version of Ubuntu that will fit on a CD-R, the iMac has no DVD reader.Where can I find this?Also, I'm not sure how to get the iMac to boot from disc. It doesn't seem to respond to holding 'c'. Also, when I hold 'option' during boot up it shows me a screen with a picture of a lock, it wants me to fill in a password, but my user's password won't work.

I have an imac 27'' i7 and cannot get to install ubuntu.
I always get a blank black screen when during installation even when I select the "safe graphic mode". During installation, the i get some multi-colored straits at some point and then nothing, it returns to the black screen.
I even tried to partition my hard drive with Gparted and got the same blank black screen even with the "safe graphic mode" option.

I am finally coming around to selling my iMac G3s and eMac. I will reformat the drives in them and put on Puppy Linux for the iMacs and Xubuntu on the eMac. If I can, I will repair OS X on them all and will dual boot if possible. All of this will be done using the Intel iMac via Firewire. I would like to know if there is a way to make these machines any faster (without money) and "safer" so the next owner feels sure they won't be failing on them soon.

I presently have an iMac G4/700Mhz machine I want to try Ubuntu on, but I cannot get it to boot using the 10.04 PPC Live CD. I get to the boot prompt, and no matter what I type, the system halts when the screen clears and comes up, and each time it does so, it comes up different colors (I've seen green, red, yellow, and grey so far). I've tried the special boot arguments that apply to this system when you press the TAB key, and all of them end the same way, so I'm at a wee bit of a loss here.

Here's the next problem I'm running into. I successfully installed Ubuntu using the Alternate disc. It's set up as the only OS, I let the installer configure the internal drive, etc. I don't need OS X on this machine anyways. I'm back to the graphics issue again.The system turns on, fires up YaBoot, starts up the Ubuntu install, but then hangs as soon as it goes to do something with the display adapter, producing a random blank screen in a particular color, and just stops there. I looked to see if there were boot options at the YaBoot prompt, but all it gave me were "Linux" and "Old".

After few days of Googling, downloading and testing, I've finaly managed to make a working Xorg.conf for my iMac G3 (Slot-loading, Summer 2001). As many of configs found on the Internet wasn't working for me, I'm posting mine, which is based on data from many configs (some from Ubuntu 8.04, were not working on this new release without adjustments).

I'm trying to boot ubuntu10.4 live CD on my new iMac (iMac 11,2, core i3). The screen goes black at start of boot and stays black. The CD stops reading after a few minutes and that's that. Just to see what else doesn't work I tried ubuntu10.10 beta live DVD. That boots the splash screen - already better than 10.4 - and gives the language menu and the boot option. The boot starts and some text scrolls up the screen quickly. Then the screen goes black, etc. Tried to set boot option vga=771 - no good. Boot option nomodeset - no good. Booting suse11.3 live CD also gives scrolling text and a black screen. All these discs worked on my old Mac Mini Solo (2006). Looks like something's different about booting a live CD on the new iMacs. Anyone else trying this?
