• Ubuntu not booting after install from USB (kernel panic?)

  - by user287782

  After booting fine frome a live USB I installed it and everything was going swimmingly but when I try to boot from the hard drive it just stops and I have to do a hard reboot. I tried booting into grub as recommended in other questions but it wouldn't work. Here is a photo of the boot once stuck: Same for recovery boot: I've got an Asus K43SJ laptop with an intel i5, 4Gb of RAM, an nVidia GeForce GT 520M and a 750Gb hard drive.

• Sempron 145 core unlocking

  - by Grant

  Call me a cheapskate looking for performance, but I have a Sempron 145 processor that has been unlocked to an Athlon II X2 4450e with a GIGABYTE GA-990FXA-UD3 motherboard, but only one of the two processor cores can be used at a time. If both of the cores are enabled in the BIOS the kernel will hang during boot, If I reboot the system and disable the second core (but not re-lock the processor), it will take me to the grub and then start normally. Is there a way to enable both cores and boot without kernel hangs?

• How to remove Ubuntu and put Windows back on?

  - by Josev King

  I installed Ubuntu 12.04, as a dual boot on my windows Vista laptop, and the next thing I know, I get black screen with error: unknown filesystem. grub rescue> I have tried reinstalling Windows, reinstalling Ubuntu, booting from Ubuntu disk, and managed to actually get into the OS, but there is nothing I can find of uninstalling Ubuntu, and deleting the partition it created. I know nothing at all about Linux, and I desperately need to get my laptop back up and running.

• Mouse and keyboard not working after upgrading to 11.10

  - by geeehhdaa

  After upgrading to Ubuntu 11.10, neither my keyboard nor my mouse work anymore. The keyboard works during the boot process, but stops working as soon as the login screen appears. I'm stuck there because without a mouse or a keyboard I can't login or start a shell. If I hit ESC during startup to make the grub manager appear, the manager appears, but the keyboard won't work anymore. Mouse: Logitech RX 250, Keyboard: Cherry RS 6000

• How can I improve the battery life under 12.04 on my Inspiron 14z? [duplicate]

  - by cfogelberg

  This question already has an answer here: Tips to extend battery life for laptops and notebooks 24 answers How do I improve the battery life of my Inspiron 14z under Ubuntu 12.04? This laptop gets 4-5 hours of battery life using Windows (e.g. here). I've removed Windows, installed Ubuntu 12.04 and the initial battery life was only 2 hours. With some tweaks (described below) it's still only ~2.5 hours. For reference, the laptop is the latest model of the 14z: i5-3337U processor 32GB MSATA, 500GB HDD (5400rpm) AMD Radeon HD7570M graphics card I have put ext4 partitions on both the SSD and the HDD, and have mounted / to the SSD and /home to the HDD. I also put a 24gb linux swap partition at the start of the HDD, though I figure this won't be used all that much (the laptop has 8gb of RAM). After googling around and reading Ask Ubuntu and other sites extensively, I have done the following steps, and they have improved the battery life ~30 minutes (exact improvement not clear, but battery life is still nowhere near 4-5 hours). Installed Jupiter (and set Performance to "Power Saving") Installed laptop-mode-tools cat /proc/sys/vm/laptop_mode now outputs 5 (previously it output 0) But it's not clear that this will help: AskUbuntu question Turned down the brightness of my screen from full to 1/3 Other things I have heard about but have not tried for fear of frying the laptop or my linux install: Add "pcie_aspm=force" at the end of the line with "quiet splash" in /boot/grub/grub.cfg Enable ALPM, but it may already be enabled in 12.04? Enable i915 framebuffer compression Use a propietary driver for the graphics card? Turn off the graphics card? (what would happen if I relied on the internal Intel bridge?) Use TLP? Spin down the HDD more aggressively (howto, but I think laptop-mode-tools does this already) The only other thing I've noticed is that plastic just above the F5, F6 and F7 keys gets really hot. According to Jupiter my CPU temperature is only 69 celsius and the System Monitor shows CPU load at 7% so I don't think it's the CPU. Maybe it's the graphics card? Also, I've set up MongoDB and LAMP on the machine as well. When I run powertop MongoDB is high in the list, but I'm not sure if that's relevant to battery life because I'm not actually doing anything with MongoDB most of the time.

• What does 1024x768X24 mean?

  - by emersonhsieh

  I was planning to change the Plymouth screen resolution(Blame Fglrx!). When I went to GRUB-Customizer(info for that), the screen resolution menu shows (as usual) 800x600, 1024x678, 600x400, and a bunch of other things. But after I scrolled down, I saw weird screen resolutions like 1024x768 x8, 1024x768 x16, 1024x768 x24, etc. Computer screens shape like a rectangle, not a cube, so what does those extra numbers mean? Or is there a secret dimension in every computer screen that I ignored?

• Misused mke2fs and cannot boot into system

However when I log in, I only get the 4:3 display option. I can't get it to change. Under the settings:details tab it recognizes the hd4000 integrated graphics. Hoping someone could help!

• stuck in busybox after update

  - by Lyra500

  I should start out by saying that I am not very tech savvy and have done my best to understand what is going on here from reading other people's posts and have fumbled my way through several attempted fixes without getting anywhere... I run ubuntu 12.04 on an admittedly cheap laptop from ebuyer and in spite of being cheap and not a brand laptop I have never had any major problems with it. Since updating to 12.04 when it was released the boot-up process has always been slow. Logging in takes about 30secs longer than it used to and if I closed my laptop and opened it again instead of being met with a login screen I'd be met with a black screen with a white mouse. As all of these problems had a behavior-changing fix (don't close laptop, patiently wait for login, etc.) I didn't think of reporting any of the issues. Last night when the update manager prompted me that there were updates available I duly did them as I usually do. At the time a bug report came up and I cannot remember what it said but I reported the bug as I was prompted to do. Then this morning when I started up my laptop it went through the usual sequence, GRUB, purple screen with 'ubuntu' etc. and then when it tried to boot up it went into BusyBox and I have not been able to do anything to solve this. I have tried going into the GRUB menu and starting previous versions but I come to the same point - busybox. I have borrowed another rather elderly laptop with Windows Vista to try and download Boot Repair and Ubuntu and burn them onto CD. I tried downloading boot repair five times, to laptop, CD and USB. Every time it would download and burn fine but then the windows laptop would tell me that 1% did not download properly and my laptop would not run the USB or CD upon booting. I then tried to download ubuntu and make a livecd, twice, but again was told that 1% did not download properly and again my laptop will not run ubuntu from the CD upon booting even if/when I went into the f2 menu and changed the menu priority (if that's what you call it) for booting up to make sure it was definitely trying the USB/CD first. This is the message I get from busybox: BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands I have tried 'exit' but it mentions things about 'kernal panic' and 'tried to quit init!' and 'can't find /root/dev/console : no such file'. I know that the problem is probably caused by a problem with a kernal caused by the update last night, but I couldn't honestly tell you exactly what was updated and without being able to boot from a livecd I'm not sure how to go about fixing this. As I said, I am not tech savvy and have done what I can to try and find a solution to the problem but I'm starting to feel like I'm out of options. Does anyone have any ideas?

• Stop Windows boot

  Installed Ubuntu over a Windows8 trial. After installation, Windows8 still tries to boot. Wiped disk clean with Acronis and reinstall Ubuntu. Windows8 still tries to start, but goes to blank screen. Ubuntu never tries to boot. Naturally live mode works fine. What do you think of wiping disk again, install Windows7 and try using GRUB approach or do you know how to remove Windows from the cleaned disk?

• Cannot pass the login screen after upgrade to 12.04 from 11.10

  - by joksan

  I just performed the upgrade from Ubuntu 11.10 to Ubuntu 12.04 LTS. The updater downloaded all packages but a few ones that the system said were already installed. When asked for it, I chose to install the new maintainer's version of grub. Now after that my system start up to the login page, some images won't load. Moreover, after I try to login, the graphical instance does not load, it just sits there showing the mouse pointer and nothing else.

• 'mount: error while loading shared libraries: libudev.so.0 : no such file or directory' error while booting

  - by user199551

  I was trying to load a version of CGminer which was returning a libudev type error, and followed a supposed solution here but it destroyed my system (so it seems). I loaded the system in recovery mode from GRUB but all that done was actually tell me what I something is broken, do not know what to do next. I think I somehow associated a libudev.so.0 to 1 or 1 to 0, I am not sure what I did and how to fix it.

• Cannot boot into Ubuntu after installing Ubuntu 12.04 (with Windows 7 on another partition)

  - by onezanygirl

  I just installed Ubuntu on my desktop which had Windows 7 installed on it. When I restart the machine after completing the installation, It directly loads windows, I don't see the grub menu. I tried using boot-repair using the LiveCD (both recommended fixes AND fixing the MBR), it did not help. What am I missing? I have done this at least 5 other times, on different machines, and have never faced this issue before.

• Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca

  - by Marlen T. B.

  I have recently (as of July 2012) bought a HP Pavilion dv6-6c40ca laptop. It came pre-installed with Windows 7 on an MBR. I installed Ubuntu 12.04 on it on a GPT partition in what I think is BIOS emulation mode. I made a BIOS-Grub partition so the install didn't fail. That is what it is for .. right? Now I want to upgrade to UEFI mode. How would I Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca. Or is it impossible? My laptop, despite its new age may not be UEFI 2.0+ capable. If it isn't how can I install a software UEFI (i.e. a DUET such as the one by tianocore). Or is this too impossible? A link to my laptop's specs is: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03137924&tmp_task=prodinfoCategory&cc=ca&dlc=en&lang=en&lc=en&product=5218530 My laptop should have a UEFI given this link from HP http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01442956#N218. And from the link I draw a quote: That means most notebooks distributed with Windows Vista, and all notebooks distributed with Windows 7, have the UEFI environment. My laptop had Windows 7 Home Premium pre-installed. OK. Following the comments so far -- NOTE: I am trying to do this on an external drive so I can see if it works. I have partitioned the drive using GParted as a GPT drive. Created a 200MB partition at the beginning of the drive with a FAT32 file system. Given the 200MB partition a label of "EFI". Set the boot flag on the 200MB partition. What should a do next to install Ubuntu 12.04? Given the link: https://help.ubuntu.com/community/UEFIBooting#Selecting_the_.28U.29EFI_Graphic_Protocol In my first read through (just to see if I will understand everything before I start) I get to step 2.3 Install GRUB2 in (U)EFI systems The first line is Boot into Linux (any live ISO) preferably in UEFI mode. Um .. how do you tell what mode your live CD is in?! And how do you change it if the mode is wrong?

• Windows 8.1 Insufficient storage available to create shadow copy

  - by Bob.at.SBS

  [Note: After I entered the problem statement, I found this question, which is apparently the same problem. Maybe one of us will get a good answer...] I have used the "Windows 7 File Recovery" tool under Windows 8 to create system image backups to an external USB hard drive.

• How to install Ubuntu Server 12.04 in a Virtualbox VM with UEFI boot enabled

  - by Deleted

  I have a server which I'd like to install Ubuntu 12.04 on, but I've had some problems and thought it would be nice to get things working in a Virtualbox VM with the same features as the server. I want to enable UEFI-boot in the VM. I "Enable EFI" in the System / Motherboard settings for the VM. I make sure the Ubuntu Server 12.04 ISO is inserted when I boot. And yet I get stuck in the UEFI boot console when I start the VM. How do I install Ubuntu Server 12.04 in a UEFI boot-enabled Virtualbox machine?
