• Resize/Create a New Partition in GParted

  - by Charlie

  So I've been having some trouble recently with Ubuntu and decided it was time to switch to windows. But I have no ntfs partitions on my hard disk and GParted will not let me resize my one large partition (/dev/sda1) so that I can allocate some ntfs space to install windows on. Any help would be greatly appreciated, I've had this problem for quite some time now and it had just become one big headache. Thanks in advance!

• Can you apply noatime on Ext3 partitions at realtime?

  - by bzero

  an application accesses a disk directory containing about 3 million files (including directories). I would like to apply the noatime option for that filesystem and I would like to know whether I can do that while applications are running and accessing that filesystem. the command I'd apply would look like this: mount -o remount,noatime / Any experience with that? I run one single application using the file system, and it is a 100% Java application (1 JVM running). Ubuntu Version: 9.10 (Karmic) Thanks!

• no windows 7 option after recent 12.10 install and boot repair

  - by user95240

  Earlier today i installed ubuntu 12.10 beta. Grub wasn't booting, but just going directly to my primary OS Windows 7. I assumed i had partitioned incorrectly, because partitioning isnt my strong suit. I used boot repair because it was well recomanded off a live usb. Afterwards, grub appeared, but i only had options for Ubuntu, Advanced Ubuntu Option, and my hidden windows 7 recovery partition. Please help me recover my access to windows partiton. See this link for Boot-Repair report: http://paste.ubuntu.com/1266467/ ps. ran Boot-Repair a second time - no change

• Windows 7 and Ubuntu Boot issue

  - by user115137

  I had the idea to dual boot Win 7 and Ubuntu and what I did was the following: Made a clean install of win 7 using all of my hard drive, next I used the Ubuntu live cd and gparted to partition my drive to be the following: /dev/sda1 ext4 20GB (Linux root) /dev/sda2 ntfs 100GB(Win7) /dev/sda3 ext4 350GB(Home) /dev/sda4 extended 4GB(swap) The thing is, when installing ubuntu I deleted the partition win 7 creates for its boot sector and recovery and then resized the drive to look like what I mentioned, and Ubuntu installed GRUB to the MBR. When GRUB boots I can see Ubuntu but not Windows, how can I chainload it? Or should I fix the windows mbr with the windows 7 installation disk and try to set the dual boot from there? I don't really care which one of the 2 bootloaders I end up using, I just want the dual boot to work out. Thanks

• attempted WUBI install corrupted Vista

  - by oliver zimmermann

  Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!

• How do I get HDMI out working on an Acer AC700 HDMI?

  - by Kyle

  I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.

• Ubuntu Won't Install On Custom Build

  - by Dallas

  just built my first computer, trying to install Ubuntu, when I tell my BIOS to startup from disk drive it says "Please insert boot media into boot device" so I insert my burned disc and my computer thinks for a few seconds and then prompts me again. Any idea why? Tried multiple times, burned two discs, I have even confirmed that my build works by swapping hard drives with the computer I'm currently using to post this, so I'm kinda out of answers right now and hoping you guys can help me find something I've done wrong, thanks in advance for any help.

• What should be the correct ownership of /tmp /var /usr and subdirectories?

  - by sbergeron

  For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.

• System doesn't boot due to a "[drm: drm_crtc_helper_set_config] * error * "

  - by Albin

  I have a problem with the new Ubuntu 12.10. It finished installing correctly, but when I restart my computer an error message appears: [15.854296] [drm: drm_crtc_helper_set_config] * error * failed to set mode on [CRTC: 10] * checking battery state [17.814209] [drm: drm_crtc_helper_set_config] * error * failed to set mode on [CRTC: 10] and that screen does not advance.

  I am running Ubuntu 12.04 on my Dell XPS13 L322X (installed onto a flash drive). However, at boot time, the screen just turns off. I was able to access the Terminal through recovery mode though. I have tried several of the most common solutions that I've seen on forums/AskUbuntu, in vain. Please help me figure this out. Thanks!

• Planning for Disaster

  There is a certain paradox in being advised to expect the unexpected, but the DBA must plan and prepare in advance to protect their organisation's data assets in the event of an unexpected crisis, and return them to normal operating conditions. To minimise downtime in such circumstances should be the aim of every effective DBA. To plan for recovery, It pays to have the mindset of a pessimist.

• A quick look at: sys.dm_os_buffer_descriptors

  - by fatherjack

  SQL Server places data into cache as it reads it from disk so as to speed up future queries. This dmv lets you see how much data is cached at any given time and knowing how this changes over time can help you ensure your servers run smoothly and are adequately resourced to run your systems. This dmv gives the number of cached pages in the buffer pool along with the database id that they relate to: USE [tempdb] GO SELECT COUNT(*) AS cached_pages_count , CASE database_id ...(read more)

• Hibernation option went missing

  - by harisibrahimkv

  In my Ubuntu 12.04, the hibernation option was working well and fine. However, I installed Debian on another partition recently and when I again tried to boot to Ubuntu, I got a message on the boot splash screen saying : The disk drive for / is not ready yet or not present. Continue to wait; or press s to skip mounting or M for manual recovery. After logging into Ubuntu, I find that my hibernation option has gone missing. Is there anyway to recover the hibernation option?

• Linux (Ubuntu 12.10) starts up, but the main menu on the left side, and the pictograms at the upper right corner, do not show up

  - by user114220

  Linux OS (Ubuntu 12.10) starts up (user login, my personal picture of a beautiful Norwegian fjord-landscape fills the background), but the main menu on the left side, and the pictograms (battery state etc.) at the upper right corner of the screen, do not show up. This occurred yesterday quite suddenly after six or seven weeks working with Ubuntu 12.10. Then I started in recovery mode and performed a file system check (fsck) but that takes hours and finally a message ¨Sorry Ubuntu has experienced an internal error etc¨ appeared. How can I determine what has gone wrong and eventually, how can I solve it? So that I can work again using Ubuntu 12.10 (on a dual-boot system, Intel i7, ASUS P8P67 motherboard).

• Ubuntu 11.10 boot: xhost: unable to open display

  - by paulus_almighty

  I've had this papercut for a while now, it's time it was fixed. When I boot up Ubuntu, choosing "Ubuntu...generic" from the grub screen, Ubuntu fails to load. It just sits at the driver/module loading screen. What seems to be the most significant line in this output is "xhost: unable to open display" If I choose "Ubuntu...(recovery mode)" from grub then it loads OK. I don't get why this is. Out of interest I tried enabling boot error logging with #/etc/default/bootlogd BOOTLOGD_ENABLE=Yes but I'm not seeing anything in that file. ETA: I've had this problem since fresh install of 11.10. Here's lshw: $ sudo lshw -C display *-display description: VGA compatible controller product: GF104 [GeForce GTX 460] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:03:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f6000000-f7ffffff memory:e0000000-e7ffffff memory:ec000000-efffffff ioport:bf00(size=128) memory:e8000000-e807ffff

• Problem with Nvidia after update

  - by user214673

  After adding the most recent set of updates, I can't get into Ubuntu at all. I get a screen saying that I am running in low-graphics mode, 'your screen, graphics card and input device settings could not be detected correctly etc'. I can hit return and then get to the next screen saying 'what would you like to do?' however, i can't choose from the 4 options, the only keystroke that will register is escape, which takes me to a black screen with a login. I have an Nvidia GeForce 7050/nForce 610i and it has caused problems in the past, but I have always got round it by choosing to boot in recovery mode. Now, no matter which version I try to boot into I can't get into Ubuntu at all.

• Compaq Presario R3000 randomly fails to boot on 11.10, 12.04, 12.10

  - by dlfuller

  I’m trying to figure what to do with random failures to boot. My old HP Presario R3000 with AMD Athlon XP-M sometimes boots, sometimes hangs with a blank screen during boot, and sometimes hangs on shutdown. After a few boot attempts it will finally boot to the GNU GRUB screen where I usually can select Recovery Mode, then select return to a normal boot, and the thing will startup and function normally. The pattern is not repeatable and seemed to start after upgrading from 11.04. Clean installs of 12.04 and 12.10 on newly-formatted hard drives make no difference. If this might be a clue, hangs on shutdown often stop at a line with: “pcmcia_socket pcmcia_socket0: cs: IO port probe 0x3000-0x7fff: excluding 0x3000-0x30ff 0x3400-0x34ff 0x3800-0x38ff 0x3c00-0x3cff”. I did try the “acpi=off” modification from 11.10 randomly fails to boot on Compaq Presario R3000 with no change in these random boot failures. Any suggestions sure appreciated.
