How do I speed up the Macbook Pro boot time? In OSX when I boot it goes directly to the mac logo. In Ubuntu there seems to be a 10 second or more hesitation before it access my hard drive. Is there anyway to change some settings in the BIOS / EFI?
View 6 RepliesI followed instructions on https://help.ubuntu.com/community/MacBookAir3-2/Meerkat , including the post install ones. Ubuntu with GNOME 2 runs fine, but some animations in GNOME Shell are very slow, like switching to and from Overview. I tried drivers from xorg-edgers and x-swat PPAs, but things are still slow. The most relevant solution I found is http://live.gnome.org/GnomeShell/SwatList. I applied the patch
Code:
$ cd ~/gnome-shell/source/gnome-shell
$ curl http://bugzilla-attachments.gnome.org/attachment.cgi?id=157326 > shell-animations-nvidia.patch

I purchased a macbook (for cheap) without a hard drive and decided to go with Ubuntu 10.10 on my new drive.
This laptop has serious overheating issues. I installed the sensor applet and the fans are not coming on, even when the core temp exceeds 167(f). The base of the laptop becomes hot enough to fry an egg on.
I'd like to find a way to make the fans come on in an automated fashion (without having to do it at the command line each time I want them to come on). I'd even be happy with them on all the time if that will resolve the issue, as the laptop overheats until shut down / freeze every time I use it.
I downloaded and burned the 32-bit desktop edition of Lucid Lynx (ubuntu-10.04-desktop-i386.iso) but can't boot it on my MacBook model 5,2. I've installed rEFIt. When I boot from the CD holding down the C key on hearing the boot chime, Ubuntu doesn't boot. A purple background with a keyboard and the accessibility icon shows up, then the screen goes black with a blinking underscore at the top left corner. After a little while, the marker disappears and the screen goes black. After that, nothing happens. I left my MacBook that way for a couple of minutes, but still nothing happened. Any clues about what the problem may be? Should I wait longer at the black screen? I burned the CD at low speed (16x) and verified the disc after burning.

I also had a slight problem when installed ubuntu. The install itself when through fine, but after completion, i received a prompt saying that I needed to restart. after clicking ok to restart, i received a string of error, and my cd ejected. when i retstarted after that, ubuntu loaded fine, but no wired or wireless internet for me.
I've reinstalled a few times and i have the same problem. Everyone i talk to says its strange that ethernet doesnt work.
Have a 4.1 Macbook. Tried to install Ubuntu 10.4 on it. Looked at everything I can find to no end. Downloaded rEFIt, didn't help just comes up with black screen and blinking line.Then tried to boot it through Virtualbox, get an error about my Intel core not being capable of 64 bit, called apple they said that it is and the version i downloaded was the Ubuntu 32 bit anyway
View 4 Replies View RelatedI have both a bootable USB install of 10.10 Desktop, which I've confirmed on my netbook (which runs Ubuntu) works fine, and a CD install disk, and my MacBook will not boot the USB and the CD isn't working right. I have a flaky superdrive, which is why I'm attempting the USB approach as well. I burned the CD from my son's computer and I'm sure it's fine.
I'm running Leopard 10.5.8.
Thought that I would share my story of trying to get a USB thumbdrive to boot ubuntu on my MacBook Pro. I originally bought a 32Gb flash drive thinking that it would be as simple as throwing ubuntu on and pressing go. I soon found out the hard way that Apple won't let you boot BIOS(Legacy) OS's from a thumbdrive. A long learning curve later, I could successfully boot the ubuntu Kernel from my thumbdrive alone. I partitioned my drive into 4 partitions an EFI boot partition(1) a fat32 boot partition(2) an ext4 filesystem(3) and a HFS+ rEFIt partition(4).
After following the steps put forth on [URL] I was able to configure grub to properly load the ubuntu kernel, however, it would crash every time I tried booting. I edited my grub.cfg file to load /bin/sh on startup, and that got me to boot into an SH shell, but nonetheless startx would not properly load. A headache and a half later, I discovered that ubuntu does NOT like being booted from EFI. I could have continued these shenanigans and tried to get ubuntu to boot using EFI, but I took the lazy route out.
Apple does not let you boot USB from BIOS, but it does, however, let you boot CD's from BIOS. I burnt a copy of the "Super GRUB2 Disk" from [URL]. Poped it in my CD tray, held 'C' when booting, grub2 loaded, pressed 'detect os' and it booted. Everything works great, video drivers, usb drivers, everything is exactly like if ubuntu was on my HD, and to be honest the speed is GREAT - I would almost go far enough to say that it is faster than booting from a HD, the only issue is that without a SWAP partition, the memory fills up rather fast, and sometimes you have to wait for that to catch up.
To recap:
Step 1: Install Ubuntu to a thumbdrive just like you would a HD
Step 2: Burn the "Super GRUB2 Disk" from supergrubdisk
Step 3: Hold 'C' when booting -> detect OS's
Step 4: Boot from Ubuntu on you Flashdrive, Enjoy!
I've got a Macbook Pro with rEFIt and Windows 7 installed (I'm not sure if this is relevant), and I'm running into an issue when I try to boot from the LiveCD or a USB (64 bit, due to 4GB RAM).
If I boot from the CD, the Ubuntu splash shows fine, but I run into the error message:
"(initramfs) Unable to find a medium containing a live file system"
I tried then to boot from the USB using rEFIt, but it just gets stuck at the grey screen with tux. The disk images both are OK.
Trying to install Ubuntu 10.10 on new Apple Macbook Air 3.2 with USB key. I'm able to partition and install REFIT fine, but when I tell REFIT to boot from the USB key, it goes to black and says "boot error".I then tried dd'ing the USB key partition to a local partition on the Macbook Air and booting that via a suggestion from another thread. It actually started loading the purple Ubuntu bootsplash-looking background then went straight to black even before the screen to select "try" or "install". Anyone know how to get the install USB to boot?

I'd like to install Ubuntu on it because I really love the way Ubuntu is developing and becoming much more user friendly. My use will mainly be for browsing, working with wordprocessors and maybe downloading series from torrents. My question is, should I dual boot or single boot? My personal preference is to single-boot, I just like the idea of having one OS running on the machine. What are the cons of doing that? Also, If I want to dual boot just to keep the firmware updates. How much space should I designate for Ubuntu and how much for Mac OS?
I have installed Ubuntu 10.10 as the only OS on my Macbook 2,1's entire hard drive (used Live CD to reformat and install). Now I am wondering if it is possible to add a partition and install Mac OS X Snow Leopard alongside Ubuntu, for dual boot purposes. I have seen a lot of documentation for doing this the other way around--adding a Ubuntu partition to an existing Mac OS X installation, but I haven't found an answer for adding OSX to existing Ubuntu. If anyone knows anything about this
View 4 Replies View RelatedThis seems to be a variant of a problem many people have had, but after several hours trawling through various forums, I haven't seen a reliable match for my situation.In brief:Adding a third boot partition (of Ubuntu) to my existing dual boot of OSX 10.6 and Windows 7 seems to have crippled the Windows boot from working, because Grub apparently takes over the process. Yet Grub does *not* appear to be on the Windows partition.
More verbose:I have an older MacBook Pro (3.1, running Snow Leopard) that I recently refitted with a new 240GB SSD HD. With the extra space (it was previously only 120GB) I decided to add a dual boot with Windows 7 using bootcamp. This all went swimmingly well.Encouraged, I decided to follow this Lifehacker article's suggestion and triple-boot the machine with Ubuntu (I'd never used Linux before):So I now have the nice rEFIt boot partition selection screen, and, indeed, I'm up and running in Ubuntu, and enjoying it.
Only one problem: I can't get into Windows any more. If I try to go in through rEFIt *or* by holding down OPT at startup and selecting the windows partition directly, the result is the same: I get thrown into Grub's selector, and selecting the Windows partition from there leads to an error message and a dead end.Having read through numerous postings, I get the impression that Grub is doing something or living somewhere that it ought not to be, but in most cases I've seen, people had accidentally installed Grub onto the Windows partition (or indeed onto EVERY partition). So far as I can tell, this isn't the case with me. Here's my boot summary:

I have a Macbook Pro 3,1 (2007, Santa Rosa) and I'd like to install Ubuntu 10.0.4 LTS which I downloaded from this site and burned to CD on an Intel iMac.urn seems fine, as CD appears as Ubuntu 10.0.4 on the iMac desktop. Upon trying to boot my Macbook Pro from the Ubuntu CD, whilel holding down the Alt key, my boot options are the Macbook Pro hard disk and a CD icon that says Windows. (Why does it say Windows?)After selectinghis CD as the boot device, the CD starts to load, the screen goes almost darkyou can faintly see the desktop), then after about a minute the screen goes black. Throughout this time I can hear the CD spinning up and down

View 4 Replies View RelatedI've been a long time Windows user, but I've started a small firm and because of lack of funds, I've decided to install Ubuntu on my company's PCs.I have 8 PCs in total - 6 of them with Intel CPUs, and the last two with AMD CPUs. I bought the extra two computers because I've managed to find an extra two people to work at my company, and AMD-based PCs are cheaper so I've decided to buy them instead of Intel.Long-story short, I've installed Ubuntu 9.10 and boot time takes about half-an-hour. After the computers finally boot, USB hardware doesn't work at all. I was forced to buy PS/2 keyboards & mice and they both work fine after the PCs boot.I don't know what's causing this delay.I've enabled Cool 'n Quiet from BIOS.I've tried several instructions like editing the /etc/modules file.I've installed cpufreqd, tried to configure it, but it didn't work.I've check the CPU stats and my CPUs are running at 800MHz. I can't believe nobody managed to fix the 800MHz problem as I've noticed it's quite common among AMD Ubuntu users. I think I've tried almost anything that I've found on this forum.I can't keep asking my employees not to reboot their PCs. Both Chrome/Firefox crash a lot on Ubuntu so they're forced to restart their computers.The computer specs are: AMD Athlon II X2 240 dual-core @ 2.800MHz, 2GB RAM, 500GB HDD, etc.
View 9 Replies View RelatedI've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.

I'm using OpenSUSE 11.2 with all the released updates are installed. I've got an Windows Xp SP3 on the same hard drive and it's works fine. S.M.A.R.T. says the hdd is 100%. A few days ago I realized that the boot time increased and the hard drive operations takes way too much time. So currently the boot sequence takes 11-14 minutes.
I've already tried to solve this problem but no effect:
1.) cleaned up the root directory to create more free space
2.) plugged the sata cable to another port
3.) changed from AHCI to IDE and reverse in BIOS settings
4.) added ahci, sata_nv into the /etc/sysconfig/kernel file and created a new initrd
5.) searched for problems in the syslog
Just to imagine how slow is currently the system/hdd:
My laptop boot up time increased considerably (10 seconds) after allocating a virtual drive for virtualbox guest. The guest installation did not work so i removed it along with the virtual disk. Now everytime when i boot to ubuntu, after inputting my password in the login screen, it takes much longer to load the system. And during the loading time the disk activity indicator light blinks indicating the harddisk is actually busy loading the system.
I decided to search around for a possible answer and force reprofiling ureadahead does the trick Now boot time is back to what it used to be

CD works fine on my Dell, that's why I say it's verified.

Nothing.
View 9 Replies View RelatedI 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.
