• Ubuntu on a USB

  - by Sander de Lange

  I was just wondering if anyone had a good experience with Ubuntu on a flash drive... I'm installing it right now. I formatted my 16GB flash drive to Ext2 because the default file system is ext4 but that one is journaled and USB flash drives do not like journaling. I want to use this to learn Java and Ubuntu seems to be a great OS for this. I (obviously) have USB 2.0 ports where I will put the USB in. How is the boot time of Ubuntu on a USB?

• Getting Black screen after installing 12.04 on new Mac Pro

  - by Matteo

  I installed Ubuntu 12.04 on my new Mac Pro. I had some problems because bootcamp did not allow me to partition the hd without a Windows cd. I inserted a Windows cd and did the partition and then I stopped the installation. I completed the installation of Ubuntu that now works. The problem is that Grub can't start Mac OS. It sees the Mac OS X in the menu but if I try to start it I have a black screen or sometime just the boot manager. Has anyone else experienced this problem?

• Can't Enter Password in Recovery Mode

  - by Mike Lentini

  When I go into recovery mode to get to the command line, I enter "telinit 3" to drop out of root. This works on my desktop, but on my laptop it asks for my username and password, then I hit enter and the first letter of my password appears and it doesn't log me in. It then proceeds to ask me for my username and password again, and the issue continues. Am I doing something wrong? Is this a known issue with a solution? EDIT: Worked around this by going into /etc/default/grub and setting it to boot in text mode. Still would like a solution for this though.

• Ubuntu 12.04 - Unable to change brightness

  - by Raymond Standen

  So, as a number of users seem to be experiencing, I am unable to change brightness on my laptop. Using the Brightness and Lock in settings, the slider moves but brightness does not adjust. The fn keys work for volume but not for brightness. I have updated my drivers and installed all updates, however the brightness is still at maximum. I have heard that opening sudo gedit /etc/x11/xorg.conf and entering Option "RegistryDwords" "EnableBrightnessControl=1" can fix this, however when opening xorg.conf through Terminal I am greeted with a blank document... Not very reassuring. Toshiba L750 Laptop Nvidia Graphics Card Dual boot with Windows

  I installed Ubuntu 12.04 from Windows 7 using Wubi. For reasons I won't elaborate here, I had to reinstall Windows 7. Now I want to uninstall Ubuntu.

How do I completely get rid of the Ubuntu installation? Thanks.

• How to enable TRIM on LVM on Ubuntu 12.10?

  - by Siddarth Kaki

  When I reinstalled Ubuntu 12.10 64-bit on my SSD, I chose the option to use LVM in Ubiquity. I am trying to find out how to enable TRIM for my SSD. I came across this article: http://worldsmostsecret.blogspot.com/2012/04/how-to-activate-trim-on-luks-encrypted.html The article states in addition to adding discard and noatime to /etc/fstab , discard must be added to the drive (sdX_crypt) in /etc/crypttab. My problem is the only listings in my /etc/crypttab are several cryptswap; it does not list any sdX_crypt. I currently have a /dev/sda1 (ext2), which is the boot point, and /dev/mapper/ubuntu-root, which is my ext4 partition. Any ideas as to how to enable TRIM?

• How to disable framebuffer in initramfs in 14.04 server?

  - by Blangero

  Recently I'm working on ubuntu 14.04 server. While using plymouth, I have late splash and tried to fix it, I googled and got lots of suggestions on doing this: vi /etc/initramfs-tools/conf.d/splash and add: FRAMEBUFFER=y and update-initramfs -u After doing this, I got no splash at all.So I deleted the FRAMEBUFFER=y and re-update initramfs, splash came back. But after that I installed something, maybe it's remastersys or n86v or their dependencies, or something else, I got splash gone again and according to the boot.log, I think it's due to framebuffer enabled in initramfs again. I tried FRAMBUFFER=n in /etc/initramfs-tools/conf.d/splash but failed. Now I got no splash and still can't get it back. Does anyone know how to disable framebuffer in initramfs? Thanks a lot!

• How do I take an image/backup of Ubuntu partition and restore to VirtualBox VM

  - by whizkid

  I have Ubuntu 10.04 installed on an older hard disk. I recently bought a new disk and already installed Windows 7. I dont want to use the older disk anymore, and I would like to keep on using Ubuntu in a virtual machine on the new disk(to avoid the possible mess-ups of dual boot and I found VirtualBox is the best free tool for this). I wish to keep the exact same data\programs\configurations\settings I had been using in Ubuntu for so long, and avoid the tedious part of having to reconfigure so many things. How do I backup\restore Ubuntu to another disk? I would prefer a free tool to do the backup\restore.

• No 'Hardware' tab in audio and no profiles

  - by Gene

  If I run the 12.x ubuntu (latest May 2012) from the CD, I get full audio settings, and sound playing in speaker. Profiles let me change analog to digital in/out. Once I run install from the same CD onto the laptop HD, once it boots the first time, after selecting audio settings, there is no 'Hardware' tab and no way to change profiles. Worst part is the audio device is set to SPDIF so nothing comes out of the speakers. Very off how booting off the CD I can get analog audio, and installing to HD and booting seems to limit the profile to something useless. Laptop is a 5 year old Dell D820 with Nvidea 128meg video on a 1920x1200 screen and T7200 CPU. I suspect if I could get the damn HARDWARE tab back in audio settings, I could just select the proper Analog profile - just as is the case if running from a boot CD. Searched the web, no similar problems found... any help appreciated!

• Broken BURG install after backup/restore

  - by WindowsEscapist

  Long story short: BURG is stuck in text mode and I can't seem to get it back to the eye-candy. I have purged and then re-installed to no avail. I am running 12.04. The long story: I originally installed onto 12.04 using Super-boot-manager (BURG-manager) and then stopped using it in favour of GRUB because I had too many entries. I then had to backup and restore Ubuntu (partition was deleted and re-created) due to unrelated issues. I re-installed GRUB2 and booted into Ubuntu to re-install BURG, but after re-booting it appears to be stuck in text mode (looks exactly like GRUB 1). Any ideas? I know I'm not supposed to be using it on 12.04 (I think) but it worked before, so what's up?

• Set nomodeset in usb installation (efi loader with iso)

  - by Garrett

  I'm working with the studyblast solution (http://studyblast.wordpress.com/2011/08/14/guide-mac-os-x-lion-how-to-boot-a-linux-live-system-from-a-usb-drive-how-to-update-any-ocz-ssds-firmware/) to creating a live usb for osx. I managed to get Ubuntu booted but the screen looks like a corrupt/glitch image. I can just about make out the clock on the bottom right and a few icons. I've been told that this is an easy fix and that nomodeset needs to be set for the graphics card but all the solutions i find are for a hard drive installed Ubuntu where you can cd in and edit the grub file - how do you do this is it's in an iso? Thanks Garrett

• Remove kubuntu-desktop from ubuntu 12.04 [closed]

  - by Meijuh

  Possible Duplicate: How to completely remove desktop? So, I thought I managed to remove KDE completely, but apparently that did not work at all, because every KDE application is back, including the KDE splash screen. I ran sudo apt-get autoremove --purge kubuntu-desktop Then I ran sudo apt-get install --reinstall ubuntu-desktop Then I ran sudo sudo update-alternatives --config default.plymouth Then I rebooted and everything seemed to be the original ubuntu-desktop (without the kde splash screen and other KDE applications). But now, one week later I still boot to ubuntu-desktop, but like I said, the kde splash screen and applications are all back. How should I remove kubuntu-desktop?

• How to unmount a virtual cd/dvd in Ubuntu 11.1o

  - by P J Reil

  I'm new to Ubuntu 11.10 and have absolutely no idea what I'm doing. I don't now how but in downloading and fooling around with a virtual cd/dvd program I seem to have inadvertently installed it. I had to shut down my computer for a while and when I re booted it all my files and my setup was gone. I have a brand new 11.10 setup with all the programs installed that I originally had but no files or bookmarks etc.. I'm not sure, but I think I'm running in a virtual cd/dvd. I don't know how to determine if I am or not and can't boot up in my original setup. Can anyone help me?

• Sound not working for uid=1003 but working fine for uid=1000

  - by Dirk Eddelbuettel

  Sounds works for uid=1000, but not for the main user on the system, running with uid=1003. Upon boot, the Ubuntu chime clearly plays. When the user is logged in, sound test shows no input device. I looked at several of the previous questions, added the user to audio, video, pulse, pulse-access --- but still no luck. To recap: This worked perfectly in 11.04, 11.10, 12.04. It works for the default user uid=1000, it does not work for the actual user. The differing group memberships are mainly for adm, admin, sudo and the like.
