Debian Installation :: MacbookPro - Unable To Sync GPT And MBR Part Tables
Apr 22, 2011
I'm trying to install Debian 6.0.1a on a MacBookPro5,5 (intel core 2 duo - EFI firmware). I have rEFIt 0.14 and a live cd of Debian (on a usb stick). I'm installing Debian on a usb stick. The installation process goes along smoothly, but then, it's impossible to boot up the freshly installed system (I get a black screen with a blinking cursor). I read that this is a common problem but all the solutions I have found have not worked for me.
The underlying idea is that since Macs have EFI firmware instead of a BIOS, the partition tables of devices are different (GPT for EFI versus MBR for BIOS), and grub is incompatible with GPT (I know there is an EFI version of grub but it is said to not work well). So the devices must have both a GPT partition table and a MBR one. These have to be "synced".
The tools available for this are:
- rEFIt can sync the partitions, but I haven't managed to have it sync them on any other device than the main hardrive. If I sync the main hardrive, then even the live cd (which is on a usb stick) won't boot (black screen with "GRUB _").
- Debian has a tool called gptsync, which returns a message saying "no data partition in gpt table, nothing to sync".
- Mac OS X has a tool called gptsync which returns a message saying "unknown partition type detected - I'm not touching this disc".
The reason there is no data partition is that gptsync sees my main partition as "EFI system". If I could change that, maybe I could sync the partition tables. Can that be done? Also, something I don't understand is: the live cd boots fine without grub. So why do I need grub? Couldn't the system boot up without it like the live cd does?

I just used dd to clone a linux partition to a new hard drive, it had 800mb left on the old hard drive, after dd, new hard drive lists 1.29/1.3 terabytes full. Is this what happens by default in dd? How can I fix this?

I have a working system with triple boot (Macos, Debian and Windows Xp).I have total 4 partitions, EFI, Macos, Linux Ext3 and Windows Ntfs. At this point I want to split my Windows partition and turn into the new user "Home" partition. I vaguely remember that there might have been some limitations with number of partitions regarding multiple boot schemes. Does anyone have an idea if there would be any problem if I go ahead and split my Windows partition and end up with 5 total partitions on this laptop?

I am about to install Ubuntu onto my MacBook Pro (5,2).However the hardware configuration is a little unusual, and may cause complications.I have removed the optical drive, and replaced it with a SSD, onto which I wish to install Ubuntu.Since this will be the second internal HD, whatever bootloader I'm using will need to be able to see this second disk, and perhaps the MBP hardware may have trouble with this (I don't know)?My questions are the following:
1) What bootloader should I use? (I'm not sure what exactly are the distinctions between rEFIt, grub2, grub2-efi, etc.)
2) Which partition[s] should I install this bootloader on? I am confused about whether I will need to install grub2 (or grub2-efi?) on the MBR of 'sda' (the HDD), or perhaps on the 'EFI partition' on that disk (originally created by OSX?), or perhaps somewhere else, or even at multiple locations.
3) How do I perform this installation? A link to the right (up-to-date) guide would be appreciated. (I've been browsing through perhaps rather too many help pages and forums, all written at different points in time over the last few years, when the technologies (GRUB2, distros, etc) were at different levels of advancement. And in that time, people have made progress in getting various things working on MBPs, their methods will have changed, and so will their advice/recommendations.) One thing in particular that I'll need to know is what to do when running the Ubuntu installer, to direct it to put the bootloader in the right place (or maybe we won't want the installing of the bootloader[s] to be handled by the Ubuntu installer). Also, it's still unclear to me what things like 'GPT-sync' (or 'bless') do, and what role they might have to play in this.
4) How do I accomplish this without having an internal optical drive? In the past I've been unable to boot MBPs from a Linux USB drive, and I understand that there are particular MBP issues with this. FWIW, the main HDD has already been partitioned into OSX and Windows (which I don't care about being able to use, actually, so if a proposed method makes Windows unusable it's of no consequence really). As such, perhaps some installation (eg of bootloaders) can be performed from within OSX? Alternatively, I do have USB sticks and a USB external optical drive that I can use. I also have access to another computer that's running Debian, so I thus have access to any Ubuntu/GNU software tools that may be needed. Finally, I can even put the optical drive back into the MBP temporarily if necessary in order to accomplish this installation.

Im trying to install Ubuntu on my Intel MacBook Pro 13". When booting from the livecd, Im experiencing strange issues. Sometimes the partiontable and disks/partitions are not readable straight away, sometimes you can read them once (when opening gparted or the install-routine), but then they disappear after it. Sometimes they remain quite a while and "survive" all parted and other tools, and then produce I/O errors during install (after successfull partitioning).
I want to know... are these issues well known or am I the only one with such errors? Im not doing anything wrong, AFAIK. The devices just disappear sooner or later until only loop0 (cd-rom) remains.

My last Linux install was SUSE 6 on an early ISA based Pentium clone. I'm used to Unix / bash from OS X, MinGW, QNX & BeOS... none of these rely heavily on X. But I'm thinking that Linux is so popular, I'm doing a lot of my Windows stuff under MinGW, why not just stick Linux on and be done with it.So I've polled the various distros, I'm a power-user / dev so Ubuntu doesn't seem like me, and I'm not familiar enough with Linux to go Gentoo just yet, but the way I slim Windows and OS X installs down to just what I need. I love apt-get and like FreeBSD installs I've seen, but want some Linux kernel goodness for my self, so I have chosen Debian.
I grabbed the amd64 build of lenny DVD 1, partitioned up and installed a bare system that I can apt-get the bits I want later.Here's the problem... When the install completes rebooting sends the graphical login to a frequency my old Hanns-G TFT can't handle.I can Ctrl-Alt-F1 back to the terminal or boot in single user mode, and everything seems to be good until you go GUI.Here's what I've tried.
I've renamed /etc/X11/xorg.conf to /etc/X11/xorg.conf.oldI ran dpkg-reconfigure xserver-xorgI've reinstalled using both simple GUI and Expert GUI using both kernelsI've tried adding nvidia-* packages with apt-get and aptitudeI remember there used to be a frequency tuner app for SUSE 6 and XFree86, but it seems that sort of thing is depreciated in modern Linux.Info? My GFX card is an nvidia GT 220, the motherboard is an ASUS P5QL Pro, the Monitor (Hanns-G) is attached via RGB HD-15 D-Sub (sadly that's all I have access to right now) and it's native resolution is 1280x1024 4:3 @ 60Hz, but in heXPee it will sync at that resolution at 60, 70, 72 or 75Hz, though it does get fuzzy at 75Hz.I'm fairly certain that X is working, just not at a frequency my screen can display... how can I fix this from single user, or regular bash terminal?
---edit--- Forgot to mention I ran dpkg-reconfigure on the XServer. :s It didn't offer video drivers, only to change from gb 105 keyboard layout and ps/2 mouse. I set the META key to the logo key while I was there, but it wasn't really helpful in any other way.

I'm trying to figure out how to access the local part and the domain part of an email address in postfix's main.cf. For example, myname@mydomain.net has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.

we have access to one domain name , 1 internet ip address and may servers hosting different part of site. I want them all to be accessed via same web site . some of the server in our network are embedded devices.they have their specific utility being hosted on that machine. So the severs are bound to be distributed . I just wanted to know how can I access them via single ip, domain name.

I am about to make a fresh install of ubuntu 9.10 on my 160gb hdd and keep my home directory. Here I also have Windows XP installed, the swap, home and root. All of these are done manually and given names such as 'sda1', 'sda5' ect.(I do see them in system monitor > file systems) The problem is that the installer doesn't seem to show me these tables. I only get a 160gb big chunk. GParted will not show it either (but as root is running from their I guess it cant?).

I have this hdd and another with XP in it but when ever I chnage to UBuntu, the clock goes out of whack and, makes me manually change it whereas in my XP I have an atomic clock installed that I just click on 'Ping' and she's right. I've looked at heaps of downloads for similar on here but, I haven't found a free one other than a trial type that I'm not interested in, that works so, why is Linux so difficult in this regard? I will accept all the help I can get on here because I like the thought of being able to get away from Microsoft.

I installed 32-bit 10.04, and only see 2GB of the 4GB available:
Code:
$ free -m
total used free shared buffers cached
Mem: 2193 1223 969 0 57 817
-/+ buffers/cache: 348 1844
Swap: 4092 25 4066
I was expecting to see 3GB of memory (since I installed 32-bit Ubuntu), which is what I was used to on other systems, but 2GB seems odd. Is there a way to improve things?

I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?

1000.8 MB RAM
Pentium 4 2.53GHz
Free disk space: 280.9 GB
System monitor shows 56.8% total RAM usage, 15.4% swap file usage.

Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?
It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.

I am still extremely green, but I have been able to add my Debian Wheezy server to my Windows domain and I am able to connect to my Windows file server iSCSI target, but it does not re-connect at system startup. The nodes are set to startup automatically and are in my fstab by UUID. However, checkin dmesg as well as the syslog shows that iSCSI doesn't attempt to initiate a connection at boot.

After a install on a old Toshiba today everything looked fine. But when i tried to start Xorg it start but doesn't use my whole screen. It is not a resolution problem it just doesn't use the whole screen. Hopefully this explanation is understandable. On lenny i had the same issue but once i changed the console resolution size in grub everything was fine. Sadly this is not the case with squeeze. I already tried "X -configure" and had a look at the generated xorg.conf (posted below)
[code]....
After that is tried to run the generated xorg.conf but then it just frooze.

Last night I installed ubuntu 10.10 unto a macbook pro 5,5 following the instruction from the MactelSupportTeamAppleIntelInstallation however I made a mistake during the installation process. I forgot to go into advance settings and choose to install the bootloader on /dev/sda3. I'm not exactly sure why this step was needed since everything was working fine anyways, but I was wondering how can I remove the bootloader from /dev/sda and install it on /dev/sda3 without breaking anything.

I need to install fedora on my new 16 DELL servers. I will doing it through DRAC (Dell remote access console) but DRAC can mount only one ISO at a time. I am planning to do multiple installations at the same time.hence i need multiple boot.iso files for each and every DRAC console that I open for each server.The question is...How to extract just the bootable part from the fedora DVD? I don't whether it should be called boot.iso, but I hope you get my point.I believe it has got something to do with the "isolinux" folder on the DVD, but I don't know what and how.

I'd like to write a kickstart file that installs available Fedora 14 updates as part of the installation process, much as if I was doing a standard Fedora 14 installation and had enabled the 'updates' repo.
So my question is, is there an easy way to do this? I don't want to have to go down the route of downloading all updated packages and maintaining my own update repo (or indeed, creating a repo with the dependencies listed above).

I just recently installed Lenny 5.04 on my computer and when it comes to the desktop the top and bottom bars seem to be set for a lower resolution. They only go about a third of the way across the screen and if set to be at the bottom the bottom bar is only a third of the way down the screen. The logon window fits this format but most other things go full screen (games don't though).
What is it I need to change and as an aside how do I change the screen resolution if I want everything bigger (so I can read it with my old eyes)

I have a MacbookPro 5,1 with 2GBRAM, which successfully dual-boots with Ubuntu 9.04 since a year. I wish to urgently install ubuntustudio, and also wish to have one or perhaps two more partitions, where I may install the latest Ubuntu as well as another Linux distro.
Typically, think of a multi-boot scenario:
Mac OSX 10.5.x
Ubuntu 9.04 <<--working production install, not to be messed.
UbuntuStudio 10.4
Ubuntu 10.10 [just a few days left!]
Fedora or Knoppix or Debian.
if possible, i'd also like to keep one partition free and unallocated, or reformat a partition, if i ever need to install windows. any thing i'd need to watch out for in this? I've got no extra or free partitions, only free space on the mac partition, that i'd like to carve out and allocate to partitions. Also, before i begin, is there a way I can clone my entire mac+linux hard-disk so in the event of a failure i can get *everything* back, mac as well as ubuntu? I bought a hd of an identical size, but use it with Time Machine. I'd rather use it to clone the entire hd.

I wanted to try to Natty 64 on my wife's Macbook Pro 2.1 (Core 2 Duo + ATI X1600) and I got a FAIL.
Indeed the LiveCD doesn't start at all, I don't even get the Try/Install GUI, just a sort of choice:
Code:
1.
2.
Select CD-ROM Boot Type : And a blicking cursor, I have no keyboard control at all, and I can't get something other than switching off the Mac.

Creating a separate /tmp partition manually during install prevents a clean shutdown.
Setup: Debian 8 minimal server configuration (SSH only) using net install as virtual machine on Windows Server 2012 R2 Hyper-V (Gen 2).
1024 MB RAM, 20 GB VHDX, and 1 Processor, EFI boot
Packages installed: openssh-server, sudo, unattended-upgrades, bsd-mailx postfix
Application: IPv6 gateway using 6in4 tunnel
Symptoms: When shutting down the operating system (poweroff or reboot), the message
A start job is running for Unattended-Upgrades ( xx seconds / no limit ).is displayed on the console and will persist for several minutes before eventually timing out and shutting down.I've tried several different configurations. Any configuration that creates /tmp automatically (whole disk with single partition, or disk with separate /home, /var, and /tmp partitions) works fine and shuts down promptly. When I partition the disk manually (512 MB EFI Boot, 17 GB /, 3 GB /var, 512 MB /tmp, and 512+ swap) the problem occurs. I've narrowed it down to just the /tmp partition by testing and comparing various configurations (including/excluding partitions, placing partitions on a separate disk, changing the partition sizes, matching against automatic configurations, etc.).
I have also compared the /etc/fstab and /etc/default/tmpfs configuration file between working and non-working systems and cannot see any meaningful difference.
