Ubuntu / Apple :: Does Kubuntu 11.04 Have Efi Support On Its Grub
Jul 28, 2011
I currently have kubuntu 11.04 on my laptop harddrive that is in an external enclosure. it is on the outside of the machine and connect to the computer via USB.It works fine on my windows machine and I love the fact I could also plug it into my kubuntu machine at home and use it as a regular harddrive too. Although my new job basically wants me to use a mac. Apparently you need something called an efi support on my grub so here are the questions:
Does kubuntu 11.04 have efi support on its grub i.e. can I plug my hard drive with my kubuntu on via USB to a mac and boot from there? If not how could I get one? Also does getting efi support make any difference when I plug it into my kubuntu machine at home? So can I back up my data as I used to?(by simply plugging it in)Could I still plug it into my windows machine as before and work if I get efi support?
p.s. If you have trouble with heavy laptops give external harddrives a go its like carrying an ultra light linux machine (with all your data in it)!

Having successfully installed kubuntu 10.04 on my Powermac G5 I was wondering if I can install os x and dual boot, there are plenty of tutorials around but all of them involve installing kubuntu on a system with os x already installed. If there is any danger of damaging Kubuntu then I will leave it as I really don't want to go through the hell of getting it working properly again! Also I have plenty of hard drives kicking about - would it be safer/easier to install os x on it's own hard drive? And if so how would things work with yaboot?

I have an Apple iBook (ancient I know) and whenever I boot from the Live CD (Kubuntu 10.10) it boots up in 800x600 (as far as I can tell that's what it is). This would be a problem however it simplely leaves a huge black column on the right side and has a partially duplicated desktop below it.
When I go to display settings it won't let me change to a higher resolution (1024x768 is what the iBook natively runs at).
This is an iBook G3.

So I've got this old Apple with an nVidia chipset. Don't know much about Apples, but from random searches on google I think it's an imac g5.
Anyway when I install Kubuntu 10.04 it works until I update it, then the video dies. It looks as though the nouveau driver is being killed and nv put back in it's place, anyone have any remedies I might try?

I am trying to install kubuntu on my macbook. I am able to boot from the CD and install fine, but when I try to boot from the linux partition the cursor blinks for a while, then the screen goes blank.I have used the rEFIt partition utility, but when I try to reinstall the grub bootloader as described here: it says "sudo: grub: command not found"When it try "grub", it says:"The program 'grub' is not currently installed. You can install it by typing:sudo apt-get install grub"

I just installed 6.10 on an old imac g3 and everything is fine, except for the fact that i cant get any updates because 6.10 is no longer officially supported. Does support continue in the community for this release, and if so where do i find information?

One of the most long-lived discussions regarding running Ubuntu on Macs is the problem of excessive heat. There exist solutions for every single case, but they are somewhat hard for the newcomer to find.
This post is a request for a fan-control solution suitable for all macs, to eventually be put in the mactel-support repository. I know there are several fan-control solutions out there, and my hope is that this thread will single out one of them to improve upon to the point that everybody can install and use it on their mac.

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've recently bought the "new" Macbook from Apple. It obviously came with OSX preinstalled. And I'm obviously not satisfied with the way it works, I also need a FAT32 partition so I can share my files between all three OS's. Tricky business. And I thought later on I might try and create me a nice LFS system to learn about Linux and show of to my mates. But doesn't a single hard drive only support up to 4 partitions? So off I went and got Ubuntu running besides Mac. It wasnt recognized by neither the default boot-loader nor rEFIt straight away. I had to hold alt to come up with the special BIOS or something every time I needed to use Ubuntu (always).
I got up to a point where I could run Ubuntu with wireless, sound and pretty much everything working. Until the kernel updates were installed. Somehow I (or maybe it) managed to screw up and booting had become impossible, for it would crash halfway through with kernel errors and other undefined weirdnesses. Meanwhile I had tried installing Windows 7 on a different partition. Which I found to be catastrophic also. I was forced to put up with OSX, which in my opinion is fine at what it does but it doesn't do very much for me. After a couple of tries I had to give up on fiddling with Ubuntu for I needed Windows 7 to run software for school. So my current partition layout looks like this......

I was able to make a grub.efi boot loader finally. But in the end it did not make or generate a grub.cfg, so every time i boot using this loader I get the grub bash shell and nothing else. I tried copying the on from my harddrive to the EFI folder on my flash drive but still nothing.
What i did was compile the loader from source using the directions here, then formated a 4 GB flash drive to gpt, and a fat32 File system. Then moved all of the grub items to /efi/grub. Once done i then rebooted, booted to a rEFIt cd and then used it to boot to the USB (the folder is not blessed yet). Then once i got to the loader screen its just a EFI screen, no boot choice Nothing... just a recovery bash. What am i doing wrong... did i do a step wrong, did i compile wrong? What?! could some on PLEASE tell me how to get the EFI grub to make/use a grub.cfg file!

I've been following the instructions for the Mactel team and they say to put this into the terminal:
Code:
But it always gives me this:
Code:
I really need this because i believe this fixes a lot of driver issues. Im running the latest MacBook Pro (intel i5 / MBP 6th Gen).
I'm having severe driver issues, i think these fixes these, right?
- No sound
- Special buttons like brightness, sound, etc show up on Ubuntu when pushed but nothing actually happens. Same with the Eject button. Shows a status bubble in the top right that it's ejecting, but doesn't do anything.
- The touchpad, as it has no buttons on the Mac, is nearly not useable, but they say it works out of the box...
Also, side question... can you change control to be cmd? Like, swap them to match the Mac's layout?

I tried to install the H.264 decoder and MPEG=4 AAC, by going to Install/Remove software in openSUSE 11.3 and found h264enc - H.264/MPEG-4 Encoder Frontend,I installed it but nothing seemed to happen when it comes to viewing Quicktime movies. I also noticed that when I right-click on the Quicktime screen, it gives me the option to play the video using Banshee. I then launch it and I doeble click on the video that is listed, the banshee logo flashes and nothing happens. Can someone tell me a way to resolve this, is there a way to resolve it.

Trying to change with the entry of grub:
sudo kate /boot/grub/grub.cfg putting "Windows 7" in place of Windows Recovery Environment (loader) on /dev/sda2.
Just launch the command sudo update-grub charge me more:
-Found linux image: /boot/vmlinuz-2.6.35-22-generic
-Found initrd image: /boot/initrd.img-2.6.35-22-generic
-Found memtest86+ image: /boot/memtest86+.bin -Found Windows Recovery Environment (loader) on /dev/sda2
Windows 7 should be written here. The procedure is another?

I have a dual boot Vista/ Kubuntu and my vista SP2 has made both my vista and kubuntu unable to boot completely. I've been through many steps to recover vista but no restore point works and such so I am going to use my Toshiba recovery partition to reinstall but what I'm wondering is if after I do that will the grub loader be affected and give me the error 22? The two are on separate partitions and I've been meaning to get rid of Kubuntu from my laptop since I have it on my pc

My system has 2 hard drives, a 400gb master and a 250gb slave. sda (my main 400gb Windows drive) has XP on it. The slave (sdb) has 3 partitions:
sdb1 is for my downloads (NTFS ~180gb)
sdb2 has Kubuntu 8.10 installed (ext3, 60gb)
and sdb3 is the swap (3gb).
I want to do a destructive upgrade to Kubuntu 10.10 - I have the CD already and burnt. I know I have to select the partitions manually due to the complicated setup, I know I need to format the sdb2 partition to ext4, mount point /, and the swap can stay the same. On which hard drive should I install the bootloader? I can't remember where it is installed now, all I know is I had a lot of problems with the install.

I have been successfully triple-booting Windoze and 2 varieties of Linux on my desktop for some years now with very few problems. The latest configuration which I have been using for 6 months or so is Kubuntu 10.04 & Ubuntu 10.04. The last version installed was Kubuntu 10.04 and on installation it's version of grub found Ubuntu 10.04 no problem (other than a minor problem with partition numbering which was manually fixed) and all was well.
I have just upgraded Ubuntu 10.04 to 10.10 (by clean install rather than version upgrade) and the new grub from Ubuntu 10.10 will not start the existing Kubuntu 10.04, I just get "error: file not found".The grub.cfg file from Ubuntu 10.10 is completely different (copy attached) but the partition references & numbers etc. are correct so why will the existing Kubuntu 10.04 not start ? Windoze starts OK.

I had my Laptop, a Dell Inspiron 1520, running Windows 7 and Windows XP - I had a few gigs of unallocated space, so I decided to install Kubuntu alongside it, worked fine no problem, with the exception of running out of space very quickly - I got fed up with it, and installed Kubuntu over the Windows XP partition (around 80gigs, and the first OS to be installed on the computer). After I installed it.
All was working perfectly until I rebooted to discover I am missing my Windows 7 boot option in GRUB, before I had to press Windows XP Embedded and it opened the boot dialog, but here I dont get the option, is there a GRUB 2 option I can change to allow it to show Windows 7? The Computer works perfectly, it's just the GRUB doesn't show Windows 7, and I'm hesitant to format its old partition and reinstall it due to the fact that it may over ride the grub and leave me without Kubuntu access?

I recently installed Kubuntu with the windows installer wubi. Everything has gone fine until today. When i turn on the pc i normally have a prompt to go to windows or kubuntu. I choose Kubuntu and it loads it up. But now it goes to a grub prompt and i have no idea how to fix this or get into Kubuntu.
Things i did before the last reboot that may have caused this.
I edited my swappiness to help speed things up at the advice of many websites.
Example: url
I changed it from 60 to 10. I did this by adding the line "vm.swappiness=10" to the end of sysctl.conf
I noticed that there was a # or something at the beginning of every line in sysctl.conf and i did NOT add it to my line. This is my guess as to why i am having problems.
The other thing i did was some bug updates. Something was popping up down by the clock area and it was asking me to do some bug updates of some sort. I said yes.
Any idea on how i can fix this? As of now i cannot get into kubuntu at all. It just gives me a grub command prompt.

I have used openSUSE for a long time, but was trying to install Kubuntu 10.10 in addition to opensuse 11.3 and Windows 7 on a Gateway desktop (1500 GB hard disk & an external drive with 1000 GB. From the CD with the isoimage I got the live version and then decided to press install. I chose to follow the suggested choice of partition: About half of the external drive (500 GB) was allocated to Kubuntu while the internal hard drive contained Windows 7 and opensuse.
Everything went well until I was asked to restart the computer. I got a black screen with the message:
error: no such device: 64e3ffcl-c003-482a-87f3-89489e5e067d. grub rescue> At this point the only command that will not respond with Unknown command .. is 'ls' which gives: (hd0) (hd0,msdos9) ... (hd0,msdos1) (hd1) (hd1,msdos2) (hd1,msdos1) (fd0) (fd1)
I am now ***completely lost***. The only step that gets me out of this screen is ctrl-alt-del which causes a reboot and brings me back into the same situation. The ***computer is useless*** until this is resolved.

I have installed latest kubuntu (10.04) on sda7, ext4 , and i selected the advanced feature of the installer to install kubuntu bootloader on sda7. 11.1 is on sda5 .First , it destroyed my 11.1 grub bootloader on mbr . I managed to restore it with the 11.1 installation DVD. Now i try to boot kubuntu from the sda7 bootloader, without success . I searched the forums and tried some hints i found but found no similar problems. Here are the different entries i tried on grub (mbr) , content of the /boot/grub/menu.lst :

I decided that I wanted to take Arch for a spin for the next week or so (I've had Ubuntu installed for a while) and so I thought the logical thing to do was to erase my partitions and start over with a new live cd...
Well.. that didn't work. I tried to do it from Disk Utility in OS X which succeeded in deleting most everything... EXCEPT grub is still in the mbr (or whatever it runs from through rEFIt). But all I see when I start up in the non-OS X partition is:
Code:
GRUB
At any rate, no Live CDs work, I can't delete the partitions from OS X (including after booting up from the OS X Install disk).
If I hit F1 I can get the "grub>" prompt. But I can't figure out how to launch a live cd. To my knowlege, there's not a "bios" for rEFIt where I can force it to boot from CD, is there?

I have OS X, Ubuntu 10 x64 and Windows 7 x64 installed on my Macbook Pro new unibody. Right now when I choose Windows or Linux in the rEFIt boot menu both options take me to the GRUB menu, and I can boot everything but it's a bit redundant and annoying.
