• How large of a swap partition is needed to hibernate?

  - by Closure Cowboy

  I've read this question, but it doesn't definitively answer my question. If I want my computer to be able to hibernate, do I need to have a swap partition as large as my RAM, or will Ubuntu wisely be able to hibernate if the swap partition can fit the currently-in-use RAM? I'm about to install Ubuntu on a computer with a lot of RAM, and a relatively small hard drive, so I don't want to use more hard drive space than necessary. I wanted to avoid giving my actual specifications to keep this question more general, though I'll give them if necessary.

• First time user here

  - by Brian

  Never used Linux before but I decided I want to start somewhere and Ubuntu seemed like the right place to start. I burned the 64bit version iso onto a CD and installed it onto a fresh new hard drive I got and it installed nicely or so I thought. First major problem was the fact that the screen slip oddly, second when I tried to log in everything just kind of froze, I could still move the cursor but thats it. I'm not too tech savy but I can follow instructions and any help given would be greatly appreciated. I am considering dual booting it with my other hard drive that has windows 7 on it but I'm afraid I might mess that up, plus if I do it that way I wouldn't know how to get rid of Ubuntu if I decide its not for me.

• After upgrade to xubuntu 12.10 I have 2 mount points for each partition

  - by TiGR

  Just upgraded Xubuntu 12.04 to 12.10 (both XFCE and LXDE desktops are being used at this system). Now I have 2 mount points for each partition.

• How to create a bootable USB stick?

  - by Deborah Shadovitz

  I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me). Questions: What format do I choose for the USB stick? (I wish the instructions stated this). What is Dash? (Will I know when I run the installer?) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

• Ubuntu installer thinks my drive is empty, does not see windows paritions.

  - by John

  Hello, I am trying to install Ubuntu10.10 64bit. I just installed Windows 7 64bit moments ago. My drive is currently partitioned like so: 100MB Boot partition (automatically made by windows 7 installer) 390GB Windows partition ~1.6TB free space When I go through the Ubuntu installer it does not give me the option to install alongside another operating system. My only options are to use the entire disk or to specify partitions manually. When I chose to specify partitions manually it tells me that the drive is all free space! Windows is still booting and behaving normally, and I had not doing anything in Windows yet (had simply installed, booted for first time, then immediately restarted). I am even able to mount the windows partition within Ubuntu Live CD, and see it in the disk viewer (not gparted). Gparted in Ubuntu Live CD again reports no partitions, all free space. Not sure what to do :S. I have installed Windows7 alongside Ubuntu countless times, even Ubuntu 10.10. Thank you very much for your help :).

• Using versioning for settings in home?

  - by maaartinus

  I planned to use git for the important files in my home directory, so I can revert bad settings or transfer them to another computer as needed. But there's too much chaos there, with each program mixing wildly temporary files, caches, logs, backups, and everything. Finding anything worth saving is hard, and when I've found any settings done by myself, there were mixed with informations specific to the computer (so I could hardly take them to another one) and timestamps (so tracking useful changes is hard). Is anybody doing it or is it just hopeless? How to filter out the garbage?

• Can I give my app my own ads? (iOS/Android)

  - by aldo.roman.nurena

  I want to know if I can develop my app on iOS and Android (no matter how, that's another thread) and give them my own ads, not the ones provided by them. This way I make the deals with customers directly. Implementation does not seem to be hard. The hard question is: will I get approved on the stores? It would be a free app with 3rd-party-ads Thanks! PS: I know I can distribute APKs out of the GPlay, but I don't want to do this. PS2: bonus points for WP/BB info, but not critical

• Sudo Non-Password access to /sys/power/state

  - by John

  On my computer, pm-hibernate appears to be broken, however using the command echo disk > /sys/power/state appears to work perfectly. Now I just need regular user access to it, using sudo. How do I do this? The command sudo echo disk > /sys/power/state simply returns bash: /sys/power/state: Permission denied. Also, I need this in a regularly used script, how can I make it so that I don't have to type in my password for it to work???

  I get this error message: Archive: /home/nicole/Downloads/iLividSetupV1.exe [/home/nicole/Downloads/iLividSetupV1.exe] End-of-central-directory signature not found.

• Boot windows from grub

  - by Parth Shah

  I had Windows 7 and Ubuntu on my hard disk. I had installed Ubuntu using Wubi. To uninstall Ubuntu I deleted the Ubuntu partitions from Windows 7 Disk Management. When I re-boot my computer it shows grub rescue. What do I need to do to re-gain access to Windows? I do not have a Windows 7 DVD. Commands like rootnoverify, chainloader do not work in grub rescue. I get an unknown command error. PS: I am posting this from another computer :)

• Software/Application needed to store and organize random content [on hold]

  - by Rami.Shareef

  I have the need to store random contents (on my local hard drive/ laptop hard drive) for personal use so I can look these contents up later on when I need them. What I mean by random content is one of the following: Some sort of code Random fact Css / html / Javascript tips Or anything I might find interesting and want to keep for future reference I want to look up these entries by tags, the software should give me the ability to associate every entry with one tag or more. I have been having difficult time find applications offer this functionality, it is like a local database with search ability and easy data-entry methods. I can build one, but I don't have the time to invest in doing so. Can you refer me to any application/software that can do that, it would be great. It does not matter if it is paid or free.

• The partition table is corrupt

  - by Tim

  I have a corrupt the partition table on the laptop that is running Ubunutu 10.4. Before the partition table was corrupt I had the following partitions: 2 primary partitions: 1st - NTFS 2nd - Extended 4 logical partitons that are built within 2nd extended: 1st NTFS (68 Gib) 2nd Linux (19 Gib) 3rd Swap (1.4 Gib) 4th Linux (24 Gib) The physical order of these partitions was the following: ( 4th Linux ) - ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) The logical order of the partition was different: ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) ( 4th Linux ) NTFS partition was big and it resided between 2 Linux partitions, neither of these partitions had enough space to install Oracle 11g. Therefore, I decided to a) either move the NTFS partion to the left or b) remove it completely and extend partition where Linux resides. As I tool I have chosen GParted. But unfortunately it was not able to move the partition because he found that in NTFS partition there are some blocks that are referenced multiple times. Also it was not able to remove the partition neither, because in this case the partitions that follow it ( 2nd Linux ) - ( 3rd Swap ) have to be in his opinion also removed, because the organization of extended partition is a linked list. Since GParted was not able to do such thing I was trying to find another tool. I found diskdrake tool on PSLinuxOS distribution of linux. That tool silently deleted ( 1st NTFS ) partition and I thought that everything was fine. But diskdrake has damaged the partition in a way that I am not able either to boot from the hard disk nor to see the partitions with GParted and even with diskdrake itself! Fortunately I have a live CD of Ubuntu 8.10 and I am able to boot and see hard disk. I have 2 ideas how I can solve the problem: 1) Manually change disk partitions and point them to the correct partitions. 2) Create partition table with GParted that as much as possible is the same with the previous one I find the 2nd approach less time consuming but some data will be lost because of it is not possible to place borders of the partitions exactly how it was before. And moreover I am not sure if such approach would work, for example, if the OS is able to locate files after repartitioning. I feel like that it will but not 100% sure. Are there some ideas how the problem may be solved?

• Half the time Linux drop into BusyBox; the rest of the time the boot happens normally

  - by JoBu1324

  I just installed Ubuntu x64 onto a USB3 Drive from a DVD, and half the time it appears to skip the grub menu and boots directly into BusyBox. Since the USB3 drive is an SSD, I ran through the full installation (installing on an ext4 partition, along side a 1GB boot partition at the start of the disk), skipping the swap partition. Part of the time that the Grub Menu does shows, it boots into BusyBox with an error: ALERT! /dev/disk/by-uuid/[uid] does not exist. Dropping to a shell! What could cause such an issue?

• How do I install Ubuntu to a USB key?

  - by badp

  If you are hurrying to reply, System ? Administration ? StartUp Disk Creator -- no, that's not what I'm talking about. I want to try Ubuntu 11.04's Unity without touching my existing Ubuntu install. To do this, I need to install the nVidia drivers first (sigh). To do this, I need changes to persist a reboot. To do this, I need to really install Ubuntu on a USB key. How do you do that? What I tried I tried to make a USB key from Testdrive, then boot from it, then choose "Install Ubuntu." The installer refused to install to the installation media itself. I tried, from my installed copy of Ubuntu: sudo kvm /dev/sdb --cdrom .cache/testdrive/iso/ubuntu_natty-desktop-i386.iso ...but the installer didn't detect the disk properly.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• Bit copy of encrypted home and other partitions

  - by Mka

  My laptop is overheating so I need to save all my files before I format the hard drive. I learned how to copy dev/sdX using dd command. However, I am not sure what to copy. Picture from GParted here: http://is.muni.cz/www/256590/fig.png should I copy sda5 and sda6 only? Or sda2 and sda1? I do not need to use these data on another disk, I just want to be able to access them - therefore I want to put them on external hard drive. And last question - how I will then mount my encrypted home? Will it work? Thanks a lot!
