• Cannot mount USB disks due to "not authorized" error

  - by shadovv

  I have Ubuntu 12.04 (.2?) installed. I don't plan to need GUI after setup so I modified the grub to start in console. However, whenever I want to start up GUI I need to type startx. Simple/basic stuff. However I seem to be hitting a snag: I am having trouble mounting/accessing USB flash drives in the GUI I started in the console. "Unable to mount location - not authorized". Seemed like it should be an easy fix, but can't figure out how I'm overlooking it. Can someone help me out?

• My computer boots up with Ubuntu: How can I tell what's on my hard disk?

  - by Larry Harson

  I've acquired an old laptop (Acer TravelMate 4050 with an Italian keyboard) that boots up with the following options: Ubuntu, with Linux 3.0.0-12-generic Ubuntu, with Linux 3.0.0-12-generic (recovery mode) Memory test (memtest86+) Memory test (memtest86+, serial console 115200) When I choose the first option, the screen just goes blank with a flashing cursor. But I can go into grub command mode by typing 'c'. Now, I want to know what operating system is installed, and the files stored on my computer, so how do I do this? What can I do to maximise the use of this computer in its current state?

• Upgrading a dual-boot system HDD

  - by Jason

  I dual-boot my laptop due to lousy VM performance, and have a new 500GB/7200rpm drive coming in to replace the stock 320GB/5400rpm drive. I have the drive set up in three partitions: one for the Win7 system files, one for storage, and the third as the ext4 Linux file system. The system file and storage partitions are both NTFS. What I'm planning to do is use the system image creator built in Win7, then move that over to the new drive. However, how can I migrate the Ubuntu partition, and how do I make sure that the Grub bootloader isn't overwritten by the Windows loader?

• Ubuntu 13.04 is showing some error while opening my computer

  - by Singh

  Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

• kubuntu 12.04 won't start

  - by daker

  I have dual boot config with kubuntu 12.04 and Windows7. My problem started this morning when I tried to boot kubuntu. Everything worked fine a couple of days ago and I have not done any mayor system configurations since then. Choosing kubuntu options from grub gives me this screen A couple of minutes later this screen is shown And then it gets stuck. Have been waiting for ~5mins without anything happening. I have tried running fsck from recovery menu without any errors. I have also tried booting in failsafex mode which gives me "Fatal server error: no screens found". apt-get update gives me "Duplicate sources.list entry". I have also tried fixing broken packages from recovery menu. What should I do next?

• Ubuntu won't load properly all of a sudden

  - by Peter Raeves

  This has been the second time this has happened, but when I booted this morning my hardware wasn't detected anymore. I see both screens pop up as normal, choose Ubuntu 14.04 in the grub list and from that point onwards none of the following hardware seems to be used: VGA, DVI-D, USB, Audio jacks. This has happened before, but at that time, I still had one screen left, so I could navigate through the (non-USB) keyboard and how weird this may sound, but from the moment I opened Windows in vmware, all of my hardware started working again. This was a few weeks ago, but the same seems to have happened again. This time I can't use that little hack though, since now Ubuntu stops using both screens. My hardware is all detected, Ubuntu just doesn't want to use it somehow. Did anybody else encounter this and how did they solve this?

• "input not supported" at login screen after ati driver is installed

  - by squalo78

  I'm running ubuntu 11.10 and I installed the Ati driver from the oficial page. When i reboot, the grub and the splash screen are working (at lower resolution) but instead of the login screen, it shows "input not supported" message. If I use "Ctrl+Alt+ keypad +" I can see my login screen at 640x480 resolution and login. I don't know how to make login screen displays 1440x900@60, that is the resolution set on my session. I'm running Ubuntu 11.10 with ati hd4200 video card, a monitor acer aL1916w that supports the resolution 1440x900.

• Install Ubuntu 12.04 on Drive "D"?

  - by Bill Jones

  I have a Dell Inspiron 531S that originally came loaded with Windows Vista. A couple years ago I purchased a copy of Windows 7, formatted the hard drive and installed the updated operating system. In the process I formatted the 10 GB recovery drive partition on drive D as it was no longer needed for Windows Vista. I would really like to install Ubuntu 12.04 LTS alongside Windows 7 using the empty 10 GB drive D:. I have two questions. (1) Can Ubuntu be installed on a separate partition, a drive removed from the boot sector on drive C:? (2) If so would Grub be installed in the boot sector and properly select Windows 7 on drive C: or Ubuntu 12.04 on drive D?

• Boots to a totally blank screen after I installed some ATI Radeon card updates

  - by baboonWorksFine

  I am using Ubuntu 10.04 LTS, dual boot with win7 on ThinkPad T400, I followed Ubuntu update hints and installed some update for my ATI Radeon graphic card, but when I boot to Ubuntu(means I can still load GRUB), the tragedy happened, the screen goes to blank and no matter what key stroke, I can not get any responds, I try to go to text terminal, but impossible! However when I hit the power button, the computer would pop out the Ubuntu shutdown screen briefly and shut down. I figure out I should delete the updates package of my graphic card, but I don't even get a chance to go to text terminal, please help me!

• Ubuntu 13.10 gets stuck on boot

  - by Robert frost

  I have updated (via the Software Updater) Ubuntu 13.04 to Ubuntu 13.10. After it had finished the installation, the system required a reboot. When I reboot and load Ubuntu it will get stuck on the logo. I managed to boot into the recovery (both console and graphics mode) but I can't figure out how to repair it. I have tried a sudo update-grub, but nothing different happened. I have also tried sudo apt-get install gnome, but the same result... I am using a dual-boot Win7 + Ubuntu.

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

Can anyone help me?

• I`ve got some problems with new Acer Aspire S3

  - by xcariba

  I just got a new Acer Aspire S3 Laptop, and I've installed Ubuntu on it. Here is some problems: 1. Bluetooth (AR3012) can't find any devices. rfkill shows that everything is fine, but I still can't connect to any device. (Maybe it was turned off in stock windows?) 2. Can't change screen brightness (I've tried Timex's solution with new 3.2-rc kernel and some grub options, touchpad works fine,but I still can`t use Fn+Right/Left) 3. 720p video in all players(VLC, mplayer and totem) works wrong. I found some similar problems on intel video chips with vblank sync or something like that. Video plays as it should, but i always see a line which appears on action scenes (looks like some parts of a screen updates faster) Maybe there are some solutions from similar laptops that I can find? PS I've tried ubuntu 11.04 with old kernel and linux mint 12-rc with 3.2-rc2 kernel.

• Cannot upgrade or install 12.04 - Black screen

  - by Paul

  An update from 11.10 to 12.04 failed because of a boot into black screen (Nvidia graphics card) after selecting normal boot in Grub (recovery console was available though). I then wiped the whole partition (deleting all proprietary drivers) and tried a fresh install, but could not run the installation cd because it was booting straight into a black screen again. Now I reinstalled 11.10 (and installed proprietary Nvidia driver version 173), and would like to ask 2 questions: 1 - Is there a proven method to fix this problem from the recovery console, so that I can safely try upgrading again (without much knowledge of Ubuntu)? 2 - Is there a website which I could check for updated Nvidia drivers packaged into the upgrade, so that I can safely upgrade without running into a black screen some time later on?

• Increasing Ubuntu (12.04) partition size

  - by Anatoli

  I'm running a dual boot Windows XP/Ubuntu system, and I'd like to increase the size of the Ubuntu partition at the expense of the Windows partition. I've already shrunk the Windows partition, creating a large unallocated space between the Windows and Ubuntu partitions (See linked GParted screenshot). http://s17.postimage.org/5ppnrrnot/GParted.png I'd like to move my Ubuntu partition to the start of the unallocated space, and then increase its size to encompass all of the unallocated space. Once I try and move it (Using the GParted live cd), it tells me to expect big GRUB issues since I'm moving my Ubuntu partition's start sector. What is it that I should expect, and how do I handle it? With thanks, Anatoli

• Intel GMA 4500M screen resolution problem

  - by I Heart Ubuntu

  I was previously running 10.10 on my Acer Aspire laptop. It has Intel GMA 4500M integrated graphics and worked just fine. Great display, sharp, crisp, etc. I decided to do a fresh install of 11.10 Oneiric and now am having problems. Originally I was getting the dreaded blank screen where the brightness was turned almost completely off. Some searching pulled up several easy fixes (editing GRUB). Right now I am still having one issue. The screen resolution is stuck at a max of 1024x768 giving me a distorted screen. Is there any way to fix this issue? I've Googled, searched Ask Ubuntu and also spent time on the forums looking for a solution. Thus far, nothing. Apparently, was and still is a concern in Natty? Any help would be greatly appreciated.

• Hide GRUB2 menu UNLESS you hold down Shift key: how to make this happen?

  - by Shasteriskt

  I have a Ubuntu - Windows 7 dual-boot set-up, and I would like to have it that my laptop would boot up Windows 7 unless I press down the Shift key right after boot and bring up the Grub2 menu from which I can choose Ubuntu. I researched on Grub2 and options for etc/default/grub and I have tried playing around with combinations with the GRUB_TIMEOUT and GRUB_HIDDEN_TIMEOUT values, but to no avail. I tried setting the GRUB_HIDDEN_TIMEOUT higher than the GRUB_TIMEOUT thinking that both countdown start simultaneously, but no - GRUB_TIMEOUT only starts after the other is done. Is this behavior achievable? If so, how?

• USB Mouse/Keyboard not working

  - by crstn

  I installed Ubuntu 11.10 after booting it from a USB drive. Everything worked fine there, after booting the keyboard worked in grub but not after Ubuntu was booted. I can unplug either of them and plug them in via a PS2/USB adapter and the device will work. After switching a couple of times, I got the keyboard and mouse both working via usb but after I rebooted either stopped working. How can I fix this? The mouse is a Razer Krait and the keyboard is a Logitech ClassicKeyboard 200.
