• Monitor not recognised after apt-get upgrade on 11.10 - maximum 1024x768 resolution

  - by Josh

  I did an apt-get upgrade through update manager on 11.10. After restarting my VGA monitor is no longer recognised and I can only get a maximum of 1024x768 on a 1440x900 monitor. I can't find xorg.conf so I am pretty lost! xrandr output: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 DVI-0 disconnected (normal left inverted right x axis y axis) S-video disconnected (normal left inverted right x axis y axis)

• Xubuntu fails to stay awake when the machine is under load

  - by Alex

  I have the following problem with a fresh install of Xubuntu 12.04: I set up power management options so as to send the machine to sleep after it's been idle for a while. My intention was to have it finish some lengthy numbercrunching and then fall asleep late at night when nobody's present to shut it down. What actually happened, however, is that the machine goes to sleep whenever the desktop session has been idle for the specified amount of time, and it does not seem to care at all about CPU load, and I had to disable sleep altogether. Is there any way to fix this?

• Independent sound device for headphones

  - by amfcosta

  I have an Asus K52Jc and in sound configuration there is no independent sound device for the headphones, and so there's no way to have independent volume for speakers and headphones. Is there a way to have independent devices? Or is this hardware specific? lshw reports that I have an "Intel 5 Series/3400 Series Chipset High Definition Audio". aplay -l reports: placa 0: Intel [HDA Intel], dispositivo 0: CONEXANT Analog [CONEXANT Analog] Subdispositivos: 1/1 Subdispositivo #0: subdevice #0 placa 0: Intel [HDA Intel], dispositivo 3: HDMI 0 [HDMI 0] Subdispositivos: 1/1 Subdispositivo #0: subdevice #0

• How can I use smbclient to connect to Windows shares by hostname when a firewall is enabled?

  - by skyblue

  I can't connect to file shares on Windows computers using smbclient -L //hostname when the firewall is enabled. This occurs whether I'm using ufw (which allows outgoing traffic and replies back in with the default configuration) or iptables (where I'm allowing outgoing traffic and replies back in with iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT). However, smbclient -L //ip-address works whether the firewall is enabled or not. I also tested this against a Samba server running on Ubuntu and again smbclient -L //hostname does not work when the firewall is enabled, but smbclient -L //ip-address works whether the firewall is enabled or not. For reference, here are the iptables rules I used during testing: *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -d 224.0.0.251/32 -p udp -m udp --dport 5353 -j ACCEPT COMMIT

• Java command not found

  Follow the instruction to setup the java on ubuntu 11.10 from How to install Java?. Running following command to install: sudo apt-get install openjdk-6-jdk After it success, I type "java", it prompts me with this error: The program 'java' can be found in the following packages: * gcj-4.4-jre-headless * gcj-4.6-jre-headless * openjdk-6-jre-headless * gcj-4.5-jre-headless * openjdk-7-jre-headless

• Ubuntu won't log in after update

  - by Dave M G

  I just updated Ubuntu about 15 minutes ago on my desktop which is running 12.04. Within the set of updates, there were some kernel upgrades. It didn't say I needed to reboot after the update was finished, but I thought I would anyway. The computer successfully rebooted up to the login screen. However, after entering my password, the screen goes black for a moment, then it comes back to the login screen. I tried the suggestions in this question, but unfortunately they didn't help. In the accepted answer, the questioner vaguely says it was a "Unity problem". I'm using Gnome-classic with full Compiz effects. I tried uninstalling and reinstalling Compiz, but that didn't fix anything. So... I can't use my desktop computer until this is fixed. I hope there is some help soon. I've uploaded the output of cat /var/log/Xorg.0.log to Pastebin. A temporary solution of changing to gdm instead of lightdm was found with help in the chat room.

• How to run ubuntu-tweak's janitor automatically?

  - by Eliran Malka

  My aim is to have the janitor running at startup, with a pre-configured profile (e.g. clear redundant packages and browser cache). The website is lacking any documentation or usage instructions, and I could not find any information on this here as well. I tried, naturally, to start ubuntu-tweak from the command line, hoping additional API exists that will come through in this (allegedly) simple task. I only got as far as: ubuntu-tweak -f janitor which is a step in the right direction, but what's still missing is a command for the clear action. Is such a command available, or is there any better way of achieving the desired behavior?

• CONFIG_ATH_USER_REGD variable In Ununtu

  - by BigGenius

  There is a CONFIG_ATH_USER_REGD variable in OpenWrt that allows the user to override the default settings of the wireless NIC. Unfortunately grepping the Arch kernel config doesn't seem to have that, and since OpenWrt has its fair share of hacking and patches, I don't know if that's something they added or that's provided e.g. in compat-wireless. Does this setting exists for Ubuntu or BackTrack-Linux?

• Battery icon constantly empty when discharging Vaio VGN-FZ210CE

  - by Alex

  I have a Sony Vaio VGN-210CE laptop, and its battery does not report the drain rate properly. In 11.10 and earlier, the battery icon would update with the percentage, not the estimated time. In 12.04 and 12.10, it estimates by time, which is always some very low value because the estimated drain rate is 700W. I currently have 89% in my battery but the icon is red and empty. If there is an application I should install, or a setting I should change, please let me know. Thanks!

• "Failed to mount Windows share" error in Samba

  - by Ranjith R

  This is the situation. There are 3 machines in the office. The Operating systems on them are respectively, Linux mint Ubuntu 12.04 Windows Vista The Ubuntu (#2) machine is supposed to be the common file server between the machines #1 and #3. Machine #2 has two hard disks. One is a 500 GB NTFS empty drive and the other is a 160 GB ext4 drive. My plan is to make the 500 GB as the file sharing disk. When I share a folder like ~/Documents using Nautilus context menu on machine #2, I can access the files easily on both #1 and #3, but when I try to share some folder on 500 GB disk, I get an error on machine #1 that says Failed to mount windows share I do not mind formatting the drive to ext4 if needed, but I am sure that something simple is wrong. EDIT I took @Marty's comment as a hint and used ntfs-config to configure automount of that partition. It is working now. Thanks

• Is there an equivalent of RDP?

  - by detly

  The "Desktop Sharing" settings that come installed by default seem to use VNC. VNC is a bit of a bandwidth hog, can only work at the resolution of whatever screen is attached to the host, and mirrors every action on the host. (It also seems to work poorly with compositing, but maybe that's been fixed.) I know about X tunnelling, but that's annoying to use and doesn't always work properly (or, more accurately, some apps don't work properly). Is there any kind of protocol in between the two, similar to RDP used for Windows? Specifically, something that can run at a different resolution to the host screen and is a little lighter on the network? (Ideally, the more the protocol could have in common with RDP, the better.)

• Rhythmbox - access Windows 7 Media Streaming

  - by rifferte

  I wish to be able to see and stream music to my Ubuntu 10.04 installation through Rhythmbox. I have enabled media streaming in Windows 7 and I can see Rhythmbox as an allowed device. I have installed the Coherence plugin for Rhythmbox. I can see my Windows 7 PC under the Shared folder in Rhythmbox, but I do not see any of my music. Is there a step along the way that I missed or something else that I have to enable?

  My computer will often just die randomly while I am using it. The screen goes black and sometimes displays the words TERM signal killed along with other things and sometimes it displays nothing. The writing stays on the screen momentarily before it disappears to just black. I then have to hold in the power button to turn it off and then re boot. Here are the specs... help!

• How can I add a new user as sudoer using the command line?

  - by David B

  After I add a user using adduser, I can't see it via System->Administration->Users and Groups unless I logout then login again. Is that normal? Also, can I set a newly added user as a sudoer or do I have to change that only after adding it? How can I do that via the shell? Finally, can I delete the original user that was created upon initial installation of ubuntu, or is this user somehow 'special'?

  i would like to backup my dedicated server which is my web server hosting various sites and email, so that I can update the os to Ubuntu 12.04, and basically restore back to 10.04 if things go wrong. I have a local machine that I can install 12.04 onto an then I was going to rsinc between the two, but I am fairly clueless when it comes to linux. I can ssh into the remote server and gain root access. can anyone explain if i need to backup the whole server hard drive or just some of the files? Thanks Timmo.

• how to bind super+s to indicator applete complete? - gnome classic

  - by rrosa

  i use gnome classic, i'm not a mouse fan. when i get an email while i'm writing code, i i would super+s to get to the indicator-applet-complete and read it. also to write emails, or check unread instant messages. upgrading from 12.04 to 14.04 made super+s bind to applications menu rather than the indicator applet complete. i removed the binding from the applications using dconf-editor, navigating to: org-gnome-desktop-wm-keybindings and disabling (['disabled']) the panel-main-menu key. now, how do i bind super+s to the indicator applet complete? it seems to be some how binded, since if if press super+s and then move the cursor over the applet it'll open the drop down menus (and it won't if i hover without pressing super+s) but i don't want to have to use the mouse...

• Booting Ubuntu 12.04 from external eSATA disk

  - by Lord of Scripts

  This is my system topology: Disk #1 (SATA Internal) C: D: (Windows 7 Ultimate) Disk #2 (SATA Internal) E: (Windows Backup) Disk #3 (eSATA External) H: I: (Other windows data) /dev/sdc3 Linux Swap /dev/sdc4 Extended partition /dev/sdc5 Linux / So, I originally had there Ubuntu 8.1 from years ago but never got to use it. Now I used the Ubuntu 12.04 Live CD to install on that same location (That live CD takes a century to boot on a 6GB Intel i7 system...). The installation went fine, I selected it to install on /dev/sdc5 but it never asked me for any boot stuff, where I wanted to install Grub or whatever it is that it uses nowaways (I come from the LILO days when it always worked :-) So, yet again I can't access my new Linux installation. I have to wait a century to boot the "Live" CD and it allows me to see my new installation but I can't do anything with it. I tried the approach of this blog post. Copied the linux.bin of /dev/sdc5 into C: and used the BCDEdit steps to declare the new OS. So when I boot I see the Windows Boot menu and select Linux and after than I only get a black screen with a blinking cursor on the upper left. I can boot into Windows though. So, perhaps it didn't install the boot code on /dev/sdc5? I used this setup years ago booting from Windows with a BIN file: dd if=/dev/sdc5 of=/mnt/share/C/linux.bin bs=512 count=1 I am very reluctant to run GRUB because years ago I did and it wiped out my Windows boot sector and took quite some effort to recover it and be able to boot Windows again. I have been trying to install GRUB on a blank USB stick but I can't find anything clear enough. My system does NOT have a floppy. So can someone give me some ideas about how to get control of my Ubuntu 12.04 installation?

• Can't boot ubuntu on Lenovo V570

  - by Aaron

  I recently tried to install Ubuntu on my new Lenovo V570, planning to dual boot 11.10 with Windows 7. I realized after installing that it would boot straight into Windows, so I looked up the issue. I read something about UEFI, and found a page suggesting that I wipe the drive with GParted, installing a msdos partition table, and then install Ubuntu. (I tried linux mint first, because that's what I had on my flash drive at the moment.) I attempted this, and now I'm left with a computer that won't boot anything from the hard drive. If I install Ubuntu or Linux Mint 12 using either MSDOS or GPT, it simply skips the hard drive. My BIOS has no option to disable EFI, and I'll admit I know shamefully little about EFI or different types of partition tables. I'd like to know what I have to do to make my computer boot again.

• Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

  - by John

  I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.

• How can I limit CD drive speed while on the live CD to avoid drive noise?

  - by iugamarian

  I sometimes disconect my harddisks for the weeks while only using the internet and I use the Ubuntu Live CD. But every time it needs something while in live desktop it accelerates and makes a lot of noise, also the acceleration takes too long. I want lower drive speed than acceleration lags, because acceleration lags stop me completly exactly when I need something. How can I lower the CD drive speed, say to maximum 16x, without restarting? I can't restart because I only use the CD drive, no harddisks, no flash disks, no network disks. Edit: No USB drives. Setcd does not work for the live session.

• /dev/sda2 contains a filesystem with error after partitioning

  - by Private

  I just wanted to create a separate home partition on my Ubuntu 12.10 system. I booted the liveDVD, resized the sda2 partition (28gb of data resized to 30gb based on MiB [originally on a 100gb partition]) and made a new ext4 partition for the home folder. The drive is an SSD drive. I had changed the settings (noatime etc.) for SSD succesfully a week ago. On reboot I get the following error: /dev/sda2 contains a filesystem with errors Inode 74669 has an invalid extent node (blk 6881289) fsd / [953] terminated with status 4 What would you suggest me to do? If I can avoid a clean install that would save me a lot of time (I had just done all the config). I was following this HOWTO, but I did not get to changing any of the files or configs other than those with gparted. I have a (two-week old) SSD Samsung drive which is functioning just fine (other specs see bottom of this question). Other specs: 64bit 12.10, i7, 8gb ram, nvidia.

• External Full HD monitor and Virtual Desktop Size

  - by Stefan

  I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect?
