    Does it mean that on the same computer, even the same HDD, if I wanted to, I could run 32 Bit Win7 as well as 64 Bit Linux and there would be advantages in doing so??

    I had assumed the whole system had to be one or the other and the Hard Drives all had to be 64 Bit formatted to run a 64 Bit system: though I realise that a 64 Bit system can use and run 32 Bit programs.
    Chao! , bogan.
    Great deal on success.

    On other, oh nothing really... Yes you can have 32bit and 64bit installed on same computer. The file system is independent of whether the OS is 32bit or 64bit. Advantages- For usual users, games and such run faster. For 64bit Linux there is 64bit adobe flash, so flash games and video is faster. Other than that, you might not notice. For me, I notice compiles are faster. All that is trivial, unless you're stretching things to the limits.

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hi! , MAFoElffen, Thanks for your reply. As far as the 64 Bit question is concerned, I think I will give it a miss: I do not really need more than 3.5 Gb of Ram; FSX on Win7 runs at a decent 40f/s, and my computer life is more than complicated enough already.

    For future need, when I am eventually forced to upgrade to Ubuntu 11.xx, do you have an answer to [ or a link to help answer ] my query in Post B >> P826:
    I tried to install Ubuntu 11.04 from a live CD. However, it insisted with a message saying: “No root file system is defined. Please correct this from the partitioning menu.

    How do I do that, and what should it be??
    All I can see is an option to set “ Device for boot loader installation” and I have no idea what should be selected there.
    My Windows boot is on sda1. The two Linux partitions are sdb6 and sdb8.
    By default the device is set to /dev/sda ATA WDCWD10EARS-00y (1.0 TB).
    [ Edit1: IF] I want to install it so that Ubuntu 10.10 is overwritten: should I format the partition??
    Edit2: PS: I have read your posting to "Re: 2 basic questions about dual boot with win7", which clarifies things but does not address my main query.From that I gather that 'root' and '/' both refer to the partition in which Ubuntu is [to be] installed.
    Chao! , bogan.
    {sorry for the Boldies, I could not change them.}

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Just want to thank MAFoElffen for sharing his knowledge in this thread.

    It solved all my booting problem including that of blank screen and after 20 hours or reading, installing, reinstalling, copy/pasting the stuff from here, I have a fully functional new computer, running 64b Oneiric.

    It is people like you who make Ubuntu so great. Thanks, man!

    I'd just like to echo those sentiments.

    After the most recent routine update, I was left with a black screen after reboot. It soon became apparent that there was a problem with the nvidea driver. Although this thread currently runs to an awesome 84 pages, MAFoElffen solved this for me on page 1. After following the instructions for a bit of cleaning up and blacklisting, and installing the current driver for my nvidea card, built against the current kernel, followed by a reboot, I was back in graphics heaven.

    Thanks, MAFoElffen - I am inspired to continue using linux because of people like you

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    I asked this question in another thread but have not had any answers, but this seems to be THE thread on the issue so here it goes...

    I installed 11.10 on an Acer Aspire 9800 laptop and it went well enough I thought. But it just doesn't boot up. I tried various tweaks with grub and finally managed to get to a minimal working grub menu, but then it says the dreaded "no loaded kernel" message.

    I recreated grub with sudo update-grub2 and it went without errors, found my kernels it seemed but still I get this error on bootup.

    I tried installing a operating system called WinXP but that didn't even find my harddrives so that didn't help things.

    These are the results from my boot info script.

    I recreated grub with sudo update-grub2 and it went without errors, found my kernels it seemed but still I get this error on bootup.

    I tried installing a operating system called WinXP but that didn't even find my harddrives so that didn't help things.

    These are the results from my boot info script.
    Welcome to Ubuntu!
    (And one of my 4 laptops is an Acer Aspire...)

    This thread evolved into the the graphics catchall. Even though, when something thought to be, turn out not to be graphics related, well it still gets taken care of here.

    Okay- Nvidia GeForce 7600 graphics, Intel CPU, ...

    Some preparatory questions:
    - How much memory? 1GB or above right?
    - New/fresh install of 11.10?
    - You say if get to the Grub Menu, then continues to where?
    - Does it have any messages before it breaks?
    You said "missing kernel," which is sometimes a Grub Message where it can't find the linux kernel... Or XServer when it can't find the kernel driver (such as nvidia.so).
    -Does it boot into a desktop if you use these instructions and use nomodeset instead of xforcevesa
    Temporarily Editing Grub Menu for Boot Options

    - Does it boot into a desktop if you use these instructions and use nomodset to use "Try" on the 11.10 LiveCD:
    Modesetting and the LiveCD

    - If you select a recovery menu item from the grub menu, does the recovery menu come up?
    - If it comes up, if you then select "resume", does it boot the desktop in low-graphics failsafe mode?

    I could go on, but that's a good start.

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hi!, MAFoElffen, I am back, again!, This time could you please tell me how to cure an AppArmor interface file missing problem??

    The story is a long one but bare with me, I have highlighted the bit concerning me most.

    My Win7 32Bit desktop had dual boot installations of Ubuntu 10.04 LTS and 10.10, both of which were, with a lot of help from these forums, working well.
    I wanted to upgrade to 11.10 but was put off by all the trouble I – and many others - had had with the upgrade process.
    I have made both a 11.10 live CD and a live USB Starter Disk, which this computer will boot from, though my Vista desktop on which I made it, will not.
    However, I could not get the install option to work without creating another partition, so I tried to install using dpkg and the mainline deb files for 3.0.0-12 to install it over 10.10.
    The results were as follows:
    Booting from the Grub menu to Ubuntu 10.04, 2.6.32-36, was, and still is, Ok, unaffected.
    Booting to 10.10, 2.6.35-31 was OK, but see below.
    Booting from either 11.10, 3.0.0-12-030012 or 11.10 recovery both gave a Blank black Screen with no cursor, but again, see below.
    Editing the grub menu 3.0.0-12 Linux/boot line to read ' --verbose single' ran to a line
    “ Handling starting event"
    and paused followed by several lines:
    “ init:.....r8712u: unable to load firmware “
    quickly followed by the Recovery Menu Screen.
    Crtl/Alt/F2 gave a blank Screen with a flashing cursor;
    Crtl/Alt/F7 gave a screen of lines:
    “ Cache read/write disabled: /sys/kernel/security/apparmor/features interface file missing (Kernel needs AppAmor 2.4 compatibility patch.)”
    and Warnings from /etc/apparmor.d/usr.sbin xxxx....network rules not enforced.
    It had hung on a flashing cursor that did not respond to keystrokes.

    From the Recovery Menu Screen, the 'Resume normal boot' option gave a screen of lines ending with
    “Checking battery state”
    and then a tty1 login prompt.
    Login shows
    Linux 3.0.12-030012-generic
    as does:
    Code:
     uname -r
    but then the next line shows Ububtu 10.10, as does:
    Code:
    cat /etc/lsb-release
    . After login
    Code:
    sudo service gdm start
    had no effect, ( lightdm is not recognized ).
    Running
    Code:
     sh NVIDIA-Linux-x86-270.41.19.run
    brings an NVIDIA message that there appears to be 290.10 already installed. ( Your note said that You have to have a working Internet connection to run this installer. ) So it was unlikely that it would run and reinstall, but I ran it, anyway, and it appeared to be OK.
    I then ran
    Code:
     sudu service gdm start
    and it opened the 10.10 screen, as normal but with both Network Adapters showing Disconnected.
    In nm-tools they both also showed as disconnected and both using the r8172u driver.

    The netroot option of the Recovery menu, gives a screen of DHCPD calls on eth0 & wlan0 which end in
    "no network working leases – sleeping" and repeats of ".....r8712u: unable to load firmware"
    and a root prompt.
    After reinstalling the r8172 driver and rebooting, the position was reversed, 10.04 LTS was unaffected, but 10.10 hung on the Ubuntu screen, but without the little-man Icons below.
    11.10 booted to the 10.10 screen with both wireless Adapters showing Disconnected, but no Networks listed.
    Syslog showed:
    ....r8172u: Loading firmware from “rtlwifi/rtl8172u.bin” Unable to load firmware.
    [See added note at end.]
    Re-running 3.0.0-12 with -–verbose single, gave the same results as before, the fail-safe mode gave a widget in the F2 screen, with : “Your screen, graphics card, and input device settings could not be detected correctly”, with an OK button, but no Mouse cursor, and it did not respond to keystrokes.
    Crtl/Alt/F1 then gave a screen of text for the X.Org X Server 1.9.0 Xorg.failsafe.log file, ending in:
    Code:
     (==) Using system config directory “/usr/share/X11/xorg.conf.d”
     (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
    and hung with a flashing cursor, which registered keystrokes but did not act on them, except Crtl/Alt/Del. ( I re-ran NVIDIA-config )
    Crtl/Alt/F7 showed the same screen of lines about AppArmor Warnings.
    Code:
     sudo service gdm start
    then opened the 10.10 screen.

    Later note: I have “Solved” the 'firmware not loading' problem by copying the /lib/firmware/rtl.nic & rtlwifi folders from a genuine 11.10 installation on my other computer. The AppArmor problem remains.

    I fully realize I may have fouled up things beyond recovery and may need to format the Partition and do a fresh install, but I have no idea what AppArmor does and if its absence contributes to 11.10 not showing the correct screen. Seems worth a try.

    Any other suggestions you have for repairing things, warmly welcomed.

    Any other suggestions you have for repairing things, warmly welcomed.
    On Apparmor, its working because it's actually giving an apparor warning, so if there is an actually apparmor error, it may be the apparmor-profiles or something wrong with what it is reporting on. Replacing the apparmor profiles is easy:
    Code:
    sudo apt-get install apparmor-profiles
    And check the status of them via
    Code:
    sudo apparmor_status
    But my question is why?

    You have 2 computers... each with a Windows Instance and a 10.xx Ubuntu instance. Well different now but still...
    - Why did you do another install instead of an upgrade? Doing that the drivers are already there. Some might have to reinstalled to compile against the newer kernel, as do some updates.

    - If you install into existing partition, at the partitioner > pick manual > select the partition > select mount at "/" and select format... It will format that partition and install into it.

    - Remember that you have nvidia. If you can't boot after a change > rename your /etc/X11/xorg.conf file and on boot use a "noModeset" boot parameter. (Same option for you on the LiveCD)

    - The binary ".run" file install the nvidia installer. Once the is installed, don't keep running that ".run" file. If you have a driver and want to know what version is current:
    Code:
    sudo nvidia-installer --latest
    If you want to upgrade to that latest version
    Code:
    sudo nvidia-installer --update
    Or to roll everything bcak what the way is was... The installer makes backups of everything before it changes anything. Using this option will uninstaller the driver and itse;f, as well as restore the origial options it changed.
    Code:
    nvidia-installer --uninstaller
    But to reinstall the same driver the installer says it's already installed. I thought I could find a way to froce that, but haven't found that options yet. So that takes an uninstall, then go back to the .run file and run it again.

    - "--verbose single" will bring up the Recovery menu... then if you select resume, it boots the kernel with verbose messages turn on to a tty text prompt. It's not as elegant as previous. I have a confirmed bug turned in which is upstream. If you just selected the Recovery Menu and picked Resume... it instead goes to safemode/failsafe graphics session. Yes, root goes to a root prompt... But then you see the abreviatted boot messages. Also where, if you follow the instructions, remember to remove all the sudo commands.

    - Next, if you did install in e new partition and came up with "all those errors," I might have just reinstalled it over again to see if those errors where there again or not...

    - Do this also
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    There were a few things that were quickly changed (updates) right after that snapshot.

    I guess, lets see how this goes... I'll be here to help all I can.

    Follows another two screens like this, ending:
    
    Warning from /etc/apparmor.d/usr.bin.evince (/etc/apparmor.d/usr.bin.evince line 79): profile /usr/bin/evince-thumbnailer network rules not enforced
    cat: /sys/kernel/security/apparmor/profiles: No such file or directory
     root@alan-MS-7616:/home/alan#
    The folder /sys/kernel/security/apparmor/ is empty.
    Code:
    root@alan-MS-7616:/home/alan#  apparmor_status
    apparmor module is loaded.
    You do not have enough privilege to read the profile set.
    root@alan-MS-7616:/home/alan# sudo apparmor_status
    apparmor module is loaded.
    You do not have enough privilege to read the profile set.
    root@alan-MS-7616:/home/alan#
    So what can I do about that?

    You Posted:
    But my question is why?
    You have 2 computers... each with a Windows Instance and a 10.xx Ubuntu instance. Well different now but still...
    - Why did you do another install instead of an upgrade? Doing that the drivers are already there. Some might have to reinstalled to compile against the newer kernel, as do some updates.

    - If you install into existing partition, at the partitioner > pick manual > select the partition > select mount at "/" and select format... It will format that partition and install into it.
    I could not get the Install option of the starter disk to do that, I could not find the 'Partition menu' described in the tutorials and asked for by Install; as described in my Post #833.
    I came across the dpkg method suggested by josephmills and it looked like an easy way to get 11.10 installed without all the trouble I had upgrading from 10.04 to 11.10 on my other computer - as you may recall - as also, clearly, many other people have had too.
    I did not take into account that you cannot upgrade directly from 10.10 to 11.10, which I assume is the cause of my mess-up.

    As far as NVIDIA is concerned, with the original installation I did of the 290.10 version driver, afterwards, nvidia-installer came up as 'command not found'. This time it appeared to install OK, despite what you say, and
    Code:
    nvidia-installer -- latest
    now runs and shows 290.10 to be the latest.
    I ran it again because I assumed the Blank black screens and hung Ubuntu screens were due to the driver not being installed with the new 3.0.0-12 headers. I suppose I should have tried nvidia-xconfig first.
    Also I did not rename the xorgconfig file. Should I do that now and run nvidia-xconfig again.??

    I have not yet run
    sudo apt-get update
    or
    sudo apt-get upgrade
    but Update manager says there are no updates to install and offers upgrade to 11.04.

    Thanks again!!
    Chao! , bogan.
