Ubuntu / Apple :: Replacing Karmic With Lucid On IMac 9.1?
May 14, 2010
I've got an iMac 9.1 perfectly triple booted with rEFIt with OSX, Windows 7 64x, and Ubuntu Karmic 64x. My Ubuntu side needs a refresh.
I want to redo the Karmic partition with Lucid, but I'm afraid grub2 will mess up my perfect rEFIt configuration.
I'm worried because when first doing this triple boot, I installed Karmic and rEFIt couldn't read the grub that it installed, so I installed Jaunty's grub and upgraded to Karmic. I guess it's a workaround...
Now, I'm worried Lucid will mess up the rEFIt config.
Couple of questions: Is a new install of Lucid going to mess up my rEFIt configuration? Is there a way to avoid rEFIt bugs? If a new Lucid install won't mess up rEFIt, do I simply install the grub bootloader inside the freshly installed Lucid partition?

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 downloaded Ubuntu Lucid...something onto a cd and I booted into it on my iMac G4. It brought me to a screen saying things like live is default press tab for more options etc and when I just press enter, the screen turns white, loads a few things, then it turns blank and after awhile, I hear the Ubuntu startup sound but my screen remains blank.

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:
Code:
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:
Code:
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 searched through a lot of threads on whether its safe to upgrade from a working Karmic install to Lucid via the upgrade manager. I found a few threads from around 1 month ago where some said it worked, others said they had problems with grub etc.
Does anyone know the current status of this? I would like to upgrade to Lucid but I don't know if its safe. Would it be better to use an install CD instead of the upgrade manager? Do I need to manually install grub rather than let the install program do it? (I think the upgrade manager doesn't give an option it just installs grub after the upgrade)

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 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 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 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 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 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 installed 9.10 and the graphic driver for the ATI video card. After reboot all was ok. Then I run a system update, it found almost 250 packages to update. After installation, rebooted machine and it hangs on boot.

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?

A while back, I used boot camp to dual boot OSX and Ubuntu on my iMac. It was fine, worked well - but I eventually took the partition off because there was some software corruption in OSX. I reinstalled OS X and now I want to dual boot Ubuntu. I can't! I created the partition - like last time, in Boot Camp, and I installed Ubuntu - I made sure to keep Grub on the Ubuntu partition only. But when I go to reboot (you know, after it finishes installing) I press option/alt and the Ubuntu partition does not show, only the Mac partition. Why is this?
ed: One thing that I remember is that I formatted the Ubuntu partition ext4 - I don't recall whether or not I used ext3 before, and do not know if that makes a difference.

I own a 2007 model alu' 24" iMac. I recently upgraded the RAM. Whilst researching the topic on the web I discovered this very valuable web page: [URL] I did as it said & now have 6GB of RAM in my very happy iMac. The machine is functioning perfectly just as the site said it would.
[edit:] Just a quick note to let you know that after two weeks of the usual long days & some times 24hr days, the machine has been running faultlessly.

I have eight iMac G3's that work. I've never had a mac before, and I'm not interested in anything the mac OS has to offer. I want to totally delete it, and put JUST xubuntu on these computers. I know nothing about Mac, except I got these, and they have pretty colored housings. I've tried using the 'c' and 'apple+c' commands to get this to boot from the xubuntu cd, but it doesn't have any effect. The thing just continues to load OS9.
I'm seeing from all these threads that everyone is pretty much dual booting, or multi-partitioning the hdd. I do NOT want to do this. Is it possible to format the drive completely, so that it is utterly blank, and then install xubuntu? Am I going to have to get new hdd's for them? They all work just fine, no problems except the software is so old that you can't do anything with it but use post it notes.

I have a 20" 2.0 GHz iMac G5 Rev B and I'm trying to boot the live CD on it. I used to have a small ubuntu partition before on this computer, but I repartitioned it to OS X only when I left it as a family computer. I had no problems with it back then (I think it was 10.04). I've tried booting with several options. Booting by typing in live or live-powerpc64 get the computer to a blue screen with the top bar and cursor, before the cursor stops moving, the computer freezes, and the fans kick up to full. Trying with video=ofonly gets the new left bar thingy to show but freezes as soon as I try to click anything.
