I'm trying to install Kunbuntu 10.0.4 on a late 2009 27" Core i7 iMac. Unfortunately the screen is always black while the CD/DVD installer seems to work. All firmware updates neede to the machine have been applied and it is non affected by the known problems of the late 2009 27" iMacs.
View 1 RepliesI've been installing Linux Mint with OSX on a bunch of iMacs, and its been working perfectly excpet for one of the iMacs. The screen will just go black when I boot from a live CD, but I can hear the login sound play. It's strange because all of the other iMac's run the live CD just fine. What could the problem be? I don't know what I can do to troubleshoot this problem.

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.
View 5 Replies View RelatedI tried both installing 11.3 on top of 11.2 and a new install with the same result on a couple of different mac pros (with 2009 ATI Radeon HD 4870 with 512MB of GDDR5 memory, 2.66 GHz 2x4 core Xeon 3500, 24 GB of memory). The install was done via the downloadable dvd from opensuse.org. The graphics of the install process looked fine as well as the configuration. When it came time to boot, however, the suse splash screen showed up and then the monitor went dark. The graphics seems to be frotzed. Now attempting to boot from the DVD does not cause the display to do anything. Even putting a mac DVD restore disk (and using C during boot) does not result in anything on the display). Any ideas of what the installation could have done -- seems like a no-brainer that something is screwed up with the graphics card, but I have no real proof and even less idea of what to try next.
View 2 Replies View RelatedI installed Xubuntu (Karmic 9.10) several times on an old iMac G3 with powerpc processor. Previously I had installed versions as 6.06 and 6.10 succesfully. But no luck this time. All installs were succesfull if alternate cd's were used.
The problem is that when i boot up i see the bootloader 'yaboot' and after that shortly the mouse logo from Xubuntu. After that the screen turns black and the indication light from the powerbutton turns from green to orange, this means no signal (i guess).
I assume that my screen resolution is wrong and cannot be displayed, the Mac uses 1024x768 if i am right.
My question is : How to access any configuration file to change resolution as I believe is the problem?
Edit: Perhaps there is a way to access command line to change config files.. ? Or using a live CD, but this computer is low on memory and has a hard time using live-CD's.
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 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.
View 2 Replies View RelatedScreen 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 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 have installed Debian a few times now (and other distro's), so I'm fairly used to installing linux. I'm not used to installing it on Apple hardware (back in 2009 on my laptop I had some issues that were solved rather quickly, but that's about it). Now I'm installing Debian Squeeze on a new (well, bought today, but it is the previous model: iMac 11,2) desktop iMac.
Installing goes well (resizing partition, rEFIt, booting Debian 6.0.1a netinstall CD, installing packages etc.) I followed a tutorial [URL] to install grub explicitly with force after installing and running gptsync. Everything went according to the tutorial and I rebooted to be welcomed by rEFIt and then grub: perfect!
BUT when I chose Debian in the grub-selection list, I only see a few lines of starting the kernel, and then my screen goes all black. A few seconds later I hear a sound, and iirc it's the sound of gdm prompting to select a user. I cannot switch to a TTY and I have to use the power-button to shut the system down.
It seems that there is no "safe graphic mode" or similar when running the live cd.I only get a blank screen.
View 9 Replies View RelatedI 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,
View 9 Replies View RelatedYesterday 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.
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

View 1 Replies View RelatedI'm trying to install Ubuntu on an iMac G4, and I had a promising situation the first time through but I botched the install due to my newbishness and haven't been able to boot from the install CD since.
Here's the situation:
Hardware
800 Mhz G4
256 MB RAM
15" LCD display
32 MB GeForce2 MX Video Card
"Standard" Airport Wireless Card
(more details here)
What Happened: After poking around on the forums some and reading through some of the wiki pages, I decided that 8.04 would be a good place to start, so I downloaded and burned an install disc. My first attempt booted almost perfectly, but I confused the "booting from the CD" with "installed Ubuntu" (Iknow, I know...), and promptly rebooted back into OS X.
Since then, I've been unable to successfully boot from the CD. Using the 8.04 disc, I'm prompted for what style of install I'd like, and I feebly type "live," the ramdisk loads, and then the screen goes blank, reads "loading" in the upper left for a second, the optical drive whirs for a bit, and then everything hangs on a black screen with a white cursor in the upper left. I thought I might just be impatient, so I let it sit overnight, but there was no change in the situation.
I know this isn't much information to work with. Is there a way to enable a more robust boot description? Something that will let me know what's going on when the screen goes blank and the optical drive whirs?
finally just got ubuntu to install on my emac a1002, I had to use the powerpc version. The install went fine, it restarted and loaded ubuntu, but after it loads goes to a blank black screen. And I imagine it sits there forever, yet I've only left if for about 5mins or so. The emac is from 2003, and has a 1ghz processor (Powerpc) and has 256mb ram.
View 1 Replies View RelatedI've just tried installing Ubuntu 10.04 on my powerpc. It installed fine, and booted first time ok, but since restarting it just seems to boot into a black screen. My monitor says 'going to sleep mode'
I don't think it's hanging on anything, as I can hear sounds if I play around with the keyboard. Could this be something to do with the resolution being too high? If so, can anyone tell me how I go about changing this?

View 4 Replies View RelatedJust did a fresh install of Natty B1 (previously had alpha 2).. I noticed this issue w/ A2, as well.. plugging in the exterminal monitor (via mini-displayport-to-vga connector) will do the following:
1) turn the screen on the laptop's display entirely black (but not turn it off).. i can move and see the mouse cursor.. but everything on the window appears to not rending or "painted" black..
2) external monitor never becomes active..
the only way to recover is to kill/restart X or reboot after disconnecting the extmon.. having extmon plugged in from boot produces the same results (and it doesn't seem to ever become active during boot up). sometimes this won't happen right away if i plug in the external monitor.. but opening the Monitors system prefs dialog will definitely cause (or detect displays) ,etc I waited to see if the issue would fix itself w/ the beta update, but it hasn't.. Any other 8,1 owners out there that can verify this issue? My (totally uninformed) guess is that it's due to differences in the display/gfx hardware and thunderbolt integration(?)
(I've seen a verification verifications of working-out-of-the-box.. but they were from 8,2 and 8,3 owners (which have discrete graphics cards))... If anyone's gotten this to work with some config stuff, I'd love to see that as well (since the wiki page for 8,1 says it works ootb). If someone could let me know where I should look to capture error output when the above issue occurs, that would be awesome.
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.

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.
