• How can I avoid the random restart of the xserver?

  - by Bernd

  I'm using a desktop pc with 64bit Ubuntu 12.04 (Kernel 3.2.0-24-generic). Hardware specs are - Intel Core i7 CPU 860 @ 2,80GHz x 8 - Nvidia GeForce GTS 250 - 750 GB Hard Disk ATA WDC WD7501AALS-00E3A0 (for my /home partition) - 128 GB Solid-State Disk ATA PLEXTOR PX-128M2S (for all other partitions) Since I reinstalled the PC with Ubuntu 12.04 the xserver restarts randomly. Most times when I watch a video in the browser (maybe a flash issue?) but sometimes the restart/crash appears when I'm working in an text-editor. How can I locate the problem? Which information is needed for a useful answer?

• Why does my CD Tray keep popping open?

  - by Anton

  I have Ubuntu server - Ubuntu 10.04.3 LTS and I can't figure out why my CD tray is opening all the time. I have looked into /var/log/auth.log, cron list and found nothing. The eject command closes tray and then it gets opened again. The server has a LAMP (Linux-Apache-MySQL-PHP) setup and I can't afford to restart it now. How can I find out who or which program is popping the tray open? Which programs can cause this behavior?

• Can't boot without Flash Drive plugged in

  - by vlad

  (Sorry for my bad English) I had Ubuntu 12.04 Beta installed on my computer. When 12.04 was finally released, I made a bootable USB Flash Drive using Startup Disk Creator. Then I decided to check if this drive works properly and to reinstall the system on my desktop. I must add, my desktop behaves a bit strange when it comes to bootable USB's, it recognizes them as HDD. In BIOS I changed priority of boot so USB Flash Drive (recognized as HDD) was first. Successfully booted, I installed Ubuntu. Everything worked fine, but... Now I cannot boot from my real HDD. Every time I want to boot, I put the USB Flash Drive into my computer, boot, safely remove it and everything works. What have I to do, to repair boot? Thank you for your time!

• Cloning a dual boot system from HDD to SSD

  - by Alex

  I'm planning on replacing my laptop's HDD with a 256GB SSD, but I have a dual-boot (12.04 and Windows 7) setup and I'd like to be able to directly migrate Ubuntu over without having to reinstall and lose all of my settings. GParted reports the following partition setup on my HDD. I am, of course, able to modify it if necessary. /dev/sda1 (NTFS) 66.92 out of 200.00 MB used I'm honestly not sure what this partition is for. Maybe for Windows 7 system files? I'm hesitant to mess with it. (edit; it turns out it is a partition for Windows recovery files in the event of OS corruption, so I don't want to remove it. Plus it also appears to be a major pain to remove anyways) /dev/sda2 (NTFS) 116.35 out of 339.06 GB used (boot) This partition is the C:/ drive on my Windows installation. I don't use it on my Ubuntu installation, except it is the boot partition and thus has grub on it. /dev/sda4 (extended) > /dev/sda5 (ext4) 14.49 out of 91.34 GB used > /dev/sda6 (linux-swap) 5.92 GB These are my Ubuntu partitions. /sda5 contains my documents and all of the files I use on Ubuntu, and (as far as I know) the system files for Ubuntu itself (it's the partition I created when prompted by the Live-DVD installer). /sda6 is, of course, the swap partition which I only need for hibernation (6GB of RAM). /dev/sda3 (NTFS) 9.89 out of 14.75 GB used This is an annoying partition that Lenovo created to store some drivers and files that I might need later on. For example, it allows me to use OneKeyRecovery for a quick factory recovery if absolutely necessary, not sure if that'll work on an SSD. It also contains not-so-important files for bloatware installation. In total, my HDD only has about 150GB of files on it so it should fit comfortably on the SSD. The problem is, I want to exactly migrate my files, partitions, OSes, MBR, etc. from my HDD to my SSD and I'm not quite sure how to do this. I've seen CloneZilla referenced before, but I'm not all too experienced and the documentation for it quite frankly seems a bit like a foreign language to me. So, put simply, is there any way I can exactly clone this HDD to an SSD without a massive headache? Also, if it matters, I'll probably be using an external hard drive case (as recommended in online tutorials) to externally attach the SSD to my laptop during the cloning process due to the lack of two hard drive slots in the machine.

• 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?

• Ati Radeon HD 5850 + two screens with different resolutions

  - by Nikolas

  How can I use these screens like I would use in Windows? When I turn off "copy" it gives me an error. I have tried community drivers and AMD drivers but both fail at this task. I use Ubuntu 12.04 with latest updates. It did not work in Ubuntu 11.10 either. I use DVI to connect my PC to my monitor and HDMi to my TV. It is a Sony Bravia, bought in 2008. I can't remember the model. Also, this same problem occurs when I connect to two Full HD monitors, both DVI. I cannot turn of the cloning of screens. How do I turn it off? Windows can do that.

• How to stop gecko-mediaplayer from buffering endlessly?

  - by mario

  I'm using the gecko-mediaplayer plugin (formerly "mplayerplug-in"). The totem plugin was not always working correctly with Opera, and I'm actually depending on the [Copy URL] feature of gecko-mediaplayer. However that plugin does some inept buffering of videos. It seems to default to 20% caching regardless of what you set in the preferences window. This is quite annoying for big video files. But appearantly it's by design http://groups.google.com/group/gecko-mediaplayer/browse_thread/thread/b7f0f5a3cedc8979 The Gentoo forums listed some workaround http://forums.gentoo.org/viewtopic-t-816690.html - but ~/.config/gecko-mediaplayer/gecko-mediaplayer.conf is not working in the Ubuntu version. Does anyone know the actual way to configure the cache= size. Which is the real configuration filename under Ubuntu?

• Problem with OpenGL or Unity, need Gnome fallback mode

  - by William Wind

  This question is in two parts, and I have been searching the web for days to find answers. With no luck I thought I'd drop by and ask for your help. Here goes: 1.) I'm running Ubuntu 13.04 and one day last week Unity suddenly wound't work. After the login screen, I was either faced with an all black and non-responsive screen, or sometimes it booted and I could see my desktop wallpaper (and add and remove icons/folders from the desktop). But there was no menu in the left hand side and no top bar :-( However I could still enter the terminal. I borrowed my dad's laptop and looked for a solution online. About two days later I gave up (I'm still kind of a n00b at Linux) and found a way to install Gnome Fallback, via the terminal. When I used it, I had the same problem. [clue #1] Missing menues. But if I rebooted into Gnome Fallback mode with no effects. It worked. Great! I have used that for some days now, while still trying to fix the original problem with either Unity or OpenGl or whatever went wrong in the first place. With no luck. After giving up on my search for a fix (I know that came out wrong) -- I decided to reinstall Ubuntu 13.04 from a CD. But! After that I was left where I began. When booting into my account, it only shows the desktop wallpaper and the icons. I can click and enter the folders, but not go into the menues. Last time I fixed it with Gnome Fallback mode, because I could enter the terminal and the PC was automatically online, via wireless network. But not this time, I can't get online. So: 1.) How do I via the LiveCD Ubuntu version (the one I'm using right now) install Gnome Fallback unto the harddrive based system? 2.) If impossible. How can I access the wireless Internet via the terminal, so I can install Gnome Fallback, from the "broken" Unity session. 3.) Is there any other things that I should try? Please help me, PS: My GFX-card is an ATI Radeon something and I have install and used the "Redwood" drive (I think its called) for many weeks prior to the shutdown.

• GUI Application Resolution from Text Mode OS

  - by brettw

  I'm trying to turn a computer into a Linux thin client via Ubuntu. I have a Dell OptiPlex 755 loaded with Ubuntu 14.04 installed and fully patched. I've configured the OS to run in text mode and automatically launch the VMWare Horizon's client, which works. The issue is that when the Horizon client launches, its resolution is only 1/4 of the screen. I've played with the resolution settings in grub which appears to modify the text environment but not the application environment for Horizon's. Can someone point me in the right direction on how to increase the resolution for a GUI application launch from text mode so it's full screen. Thanks!

• Battery discharges while computer is off

  - by Nuno Finote

  I bought a hp 15-r003np 2 weeks ago and installed ubuntu 14.04 LTS with dual boot (to windows 8). When i shutdown ubuntu, in the next day battery has 85% of charge, despite the computer shutdown. If i power off in windows battery charge is 100% in the next day. Does anyone have noticed the same problem? I think the network adapter is not on wol mode, seen via windows network config properties. I need help to solve this problem... (it's not right to work around restarting to windows to do the shutdown properly...)

• Booting briefly shows CLI login and then black

  - by lepusfelix

  When I boot to Ubuntu on my dualboot system, it appears to boot normally, up to the point when I would normally expect to see the lightDM graphical login screen. However, I see a CLI login screen, which I assume is tty1. Before I get a chance to actually login to it, though, it drops to a black screen with a flashing cursor. Pressing ctrl+alt+f1 does nothing. When I hit the power button on the laptop, I see the usual scrolling text as Ubuntu shuts down. I know that this is related to me having installed the proprietary ATI drivers for the video card. Purging the drivers gave me back a GUI, but unfortunately no working desktop environment, and switching to the mesa drivers returned me to the black screen issue. The only way I can get a stable working CLI is through booting to advanced options and choosing a root shell prompt, as even the failsafe X session doesn't function for me.

• Unable to install Nvidia drivers

  - by Tazzer

  a few days ago I installed ubuntu 11.10 on my friends computer. Despite all of our efforts we are unable to open the default unity and it will only open the 2d interface. I have been told in the IRC chat room that we need to install the graphics card drivers(nvidia geforce 420.) When I check the additional drivers app it doesn't show any to install. I tried installing the ones from the nvidia website but no luck, I also forgot to mention. I don't know if it means anything but he has a 64 bit computer and it is ubuntu 11.10 64bit.

• Lubuntu wireless issue with Broadcom chipset

  - by Variant Web Solutions

  I'm a web dev that just started a new venture in buying wiped laptops in bulk and selling them at a low cost to lower income families that want a laptop that will simply preform and not become virus ridden and require constant maintenance, so naturally I opted for a linux distro and after some research, lubuntu was my top pick. I'm not a stranger to linux as all of my servers for my web dev business are linux, but I am however new to L/Ubuntu and I'm having some issues with both wifi (broadcom chipsets) on the 20 or so dells that I have right now, D800's, D810's and E5400's. Not sure if you can point me in a solid direction, I've scoured (and implemented) the suggestions on ask ubuntu and still coming up short. On one of the e5400's ( though they all seem to suffer the same errors) I got the following: [code]dell-latitude-e5400@dell-Latitude-E5400:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. dell-latitude-e5400@dell-Latitude-E5400:~$ lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 92) 00:1f.0 ISA bridge: Intel Corporation ICH9M LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 2 port SATA Controller [IDE mode] (rev 02) 00:1f.3 SMBus: Intel Corporation 82801I (ICH9 Family) SMBus Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 2 port SATA Controller [IDE mode] (rev 02) 02:01.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ba) 02:01.1 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 04) 02:01.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5761e Gigabit Ethernet PCIe (rev 10) dell-latitude-e5400@dell-Latitude-E5400:~$ rfkill Usage: rfkill [options] command Options: --version show version (0.5-1ubuntu1 (Ubuntu)) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm nfc dell-latitude-e5400@dell-Latitude-E5400:~$ [/code]

• What's the story with TRIM support?

  - by Kent Boogaart

  The situation with TRIM in Ubuntu has me utterly confused. I don't know whether I need to manually run it or not. Sources I've found are disparate and unclear. I have Ubuntu 10.04 with latest updates (including kernel 2.6.32-26). I have an Intel X-25M drive with latest firmware, and it is formatted as ext4. So, does TRIM support run automatically? If not, how do I check if I need to run it, and then how do I run it if necessary?

• Where did all of the options go? [closed]

  - by Devan

  In the last version of Ubuntu I used (10.04) I had the following options, which I can not find on 11.10: Set amount of time before screen dims Show percent instead of time in battery icon Change/add screensaver Change default applications (especially in the new launcher) Also, is there any way to make it so unity opens to more apps/all instead of the current default? Basically I just need to know if there's any way to customize Ubuntu that little bit more. Any help with any of the options above would be greatly appreciated! Note: I'm a noob and don't know much about command line, so gui apps would be preferred, if possible.

• Override Built-In Maverick Keyboard Shortcuts

  - by jrc03c

  Having used the Command+M keyboard shortcut to minimize windows in OS X, I'd like to use the same functionality in Ubuntu 10.10. When I try, though, it only brings up the "communications" section of the indicator applet; like so: In the Keyboard Shortcuts preferences, I have set as the minimize shortcut Mod4+M, which I got by capturing the Apple Command key and the M key. I find no other shortcut using this key combination in Keyboard Shortcuts, and yet I cannot get the window to minimize when using it. Does anyone know how to override Ubuntu's default usage of this key combination? Thanks!

• Suggestions about php editors and file sync programs

  - by Deus Deceit

  I'm working with ubuntu and lately I decided to learn php. I have everything setup and I'm currently using aptana 3 as my php editor and for file sync. It seems like the process for file sync is too much, it has to check all files just to upload 1 file. So if someone can tell me how to update a file at once without delay, that's welcomed. I find aptana not being what I like. It's a good editor, but I would like to know if there are alternatives out there. Can someone suggest a good php editor for ubuntu?

• Proprietary Driver missing after Kernel upgrade

  - by Chris

  I recently upgraded my kernel to the Linux 3.4 kernel. Upon doing so, I found that it zapped my proprietary driver for my graphics card. As an alternative, I had saved Catalyst 12.8, but now it will not open through Software Center. I tried several other terminal methods, but it seems that many of these postings are bunk. They only work until you're almost done and then you get errors. I just need a little help from somebody who has been there, as I am new to Ubuntu. I'm kind of afraid to reboot because this is my 3rd full load of Ubuntu. Any ideas?

• Is there a current tool to build your boot / partition on hard drive?

  - by ????

  I tried Windows 8 Consumer Preview a couple months ago and it wiped out my partition table... or the boot information. So now the machine cannot boot to anything at all. Is there Ubuntu tools or Linux tool that can fix all the partition and make them boot again? (The partitions have Windows 7 and Vista on them. I run Ubuntu as a VM on Win 7). I tried another tool running on Vista and was able to see the Win 7 partition, except that tool wiped out the Vista boot info later on.

• Why won't my install on Macbook work?

  - by Wyatt

  I am trying to install Ubuntu 12.04 on my Macbook. The CD drive is broken, so I am going from a USB flash drive I created. I can get it to "Try Ubuntu" perfectly fine, as a matter of fact I'm using it right now. However, I really want to install. Everything is partitioned, rEFIt is installed. I run the installer and I follow the guide at Apple Intel Installation I get to the install part of the installer, and after running it ends with a fatal grub error. Anyone know how to get past this? I feel like it has something to do with the fact that I don't get the last dialog box of the installer with the "advanced" tab used in the guide. Any help is greatly appreciated!

• Can not get to login screen, background starts with terminal prompt only

  - by Doug

  my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?
