    Re: ubuntu 12.04 -- no gui after update -- hangs during update

    Hey Bashing:

    All that seemed to work great -- movies now playing. Thank you.

    Regarding the boot problem we worked so hard to resolve, is there a chance it is caued by a corrupted or infected harddrive? Is there an app I can use to test the drives for corruption or infection?

    Any ideas why sda does not appear in my devise list?

    Thanks, appreciate your continued support!

    ss1133xx; looking good !

    As to why sda no longer appears, will have to do some poke'n see what is.

    Checking the hard drive, I was sure we had;
    a) disk utility -> S.M.A.R.T
    b) file system check/repair -> fsck which is the front end for e2fsck.
    c) any other doubts -> testdisk.

    It is past my thinkability, so we will pick this up at a later time.

    inquiring minds want to know

    Re: ubuntu 12.04 -- no gui after update -- hangs during update

    Hey Bashing, hope all is well.

    I'd like to follow up on a couple of post-reinstall questions if you have the time and inclination to assist:

    1. sda does not appear in my devise list, so I'm not sure how to explore the contents of that drive. (It used to appear.)

    2. The pc routinely freezes up when left unattended for a period of time. For example, I boot it up, use it, then go run errands. When I get back, the screen is frozen, mouse does not respond, etc. Seems surprising for an server OS. Not sure what the cause is.

    3. "suspend" function no longer works. It used to work, before the boot-up issue that you helped me with. It takes awhile to boot, whereas when it worked, it woke from suspend very quickly. So I used to use suspend a lot.

    Any suggestions for me?

    Re: ubuntu 12.04 -- no gui after update -- hangs during update

    ss1133xx; Hey,

    Yeah, I am still around, doing well - Thank you.

    On a new install it seems strange for sure.

    1. What does - maybe the device that held the identifier 'sda' has been reassigned to another -
    Code:
    sudo blkid
    sudo fdisk -lu
    cat /etc/fstab
    relate for device identifications ?

    2. For starters, disable the screensaver and see what results (maybe #3 related ?).

    3. For suspend, what is "swap" doing ?
    What returns from :
    Code:
    free
    Maybe all these are swap related ??

    How about you close this thread as the original problem is at an end and begin a new thread on each of these new situations. If repairing swap is not the solution.
    Thread decorum is one problem to the thread - a lot like dead men -> one to a box .
    One item to one thread makes maintaining the forum ( and searching within the forum ) much easier.

    It is
    all in the process

    Thanks for assist.

    ss1133xx; Hey;

    First glance it do appear that "swap" is not set up properly.

    I am presently thinking impaired (Minor surgery) --- help me please and edit that post and place those outputs between code tags so I can see the format and so it maintains the readability.

    Please use code tags when posting output from the terminal.

    @ deadflowr; Thanks, adding the code tags helped bunches.

    @ ss1133xx;
    /dev/sda5 147863552 156248063 4192256 82 Linux swap / Solaris
    Your swap partition is ->h u g e<- . on a factor of 10; encompassing the entirety of that 'extended partition'.
    How much ram do you have installed ? -> You can activate all the applications you normally use ( and youtube too !) and with all active run the 'free' command and see what the swap usage is then, to get an idea of what the swap size should be - making that swap just a tad bit bigger than the amount of ram you have on board to accommodate the suspend function.

    I would give some serious consideration to (RE-)installing once more, after due consideration of a partitioning scheme for how I use the system - maybe a data partition and as well perhaps a 'shared - NTFS - partition to share with Windows. Might even go so far as to partition the hard disk in accord with the other hard disks as GPT. A bit more complex, and some additional home work to do to make that happen; but I bet in the long term worth that extra effort.

    Perhaps a (RE-)install will resolve all the current issues.

    Else: Make do with

    Re: ubuntu 12.04 -- no gui after update -- hangs during update

    Hey Bashing: I have 4 gb of RAM. I didn't set the size of the swap file. See your post 125, concerning the install wizard, which I followed:

    Code:
    Click on the desk top icon "install ubuntu";    
    Make sure the installer is pointed to sda ( if that is what "parted -l" relates as that 1st hard drive) at the top of the screen;  
    Choose the option " erase disk and install ubuntu"   Do Not check the boxes for "install updates" OR "install 3rd party software" 
    (we will do that after the install)
    ***
    OK so far, then is but a matter of answering the few keyboard, location and user questions, and done. ->
    Ubuntu will be installed as the only Operating System using that entire disk for it's self. The install wizard will take care of all partitioning, setting
    up "root", with /home and all other directories contained underneath "root", and as well as the "swap" partition. easy peasy.
    So I don't know why the install set the swap to a larger than normal size. (Any thoughts on that?)

    What are the implications of a large swap file? Which of the issues I asked you about do you think the swap file may be effecting?

    FYI: I recently installed Ubuntu on a laptop, using the same same install wizard instructions as those above, and the swap file on the laptop is also set to the size of the extended partition:

    Code:
    sudo fdisk -lu
    
    
     Device     Boot       Start         End          Blocks      Id    System
    /dev/sda1   *          2048    152127487    76062720   83    Linux
    /dev/sda2       152129534   156301311      2085889     5    Extended
    /dev/sda5       152129536   156301311      2085888   82    Linux swap / Solaris
    Appreciate your thoughts.
