  • How can I disable the purple bootloader splash at boot?

    - by wim
    This question has been answered before, but neither of the methods in the accepted answer worked for me on 11.10. First I tried editing in /etc/default/grub, and then running sudo update-grub. But after that I still got a blank, plain, purple screen while the kernel is loading. The screen has no boot options, and it obscures those dmesg that I want to see going in the terminal. Next I tried removing the plymouth-theme-*, but that just broke my gnome-shell theme looks, and the purple screen still remains. I have also tried configuring it with startupmanager package, but nothing seems to get rid of that darned purple splash. here are the contents of my /etc/default/grub file: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT="0" GRUB_HIDDEN_TIMEOUT="0" GRUB_HIDDEN_TIMEOUT_QUIET="true" GRUB_TIMEOUT="0" GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`" #GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) # GRUB_TERMINAL="console" # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE="640x480" # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID="true" # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" GRUB_DISABLE_OS_PROBER="true"

  • Wallpapers of only some users being dynamically loaded in LightDM

    - by Kazark
    As this answer explains: Ubuntu 12.04 Unity greeter has introduced selected user dynamic background, that means that when selecting a user from the available users list the background will change to reflect the selected user's desktop background. However, I am puzzled, because in my experience this isn't consistently true. On one of my family members' computers, where there are three users, only one of the users' background shows in LightDM. None of the users are newly created. The user whose background is showing has a custom background; one of the users whose background doesn't show also does; and the other one who doesn't has the default switching wallpaper set. It is not a clean install but has been incrementally upgraded from about 8.04. Any idea what could be happening? This is a similar question, though we're also having the opposite problem (default wallpapers not showing). (I do not have access to the computer mentioend above at the moment; when I do I will use some of the criteria given there to analyze the problem further.)

  • Custom command in right-click menu not working

    - by Luke
    I have added, via the registry, a right click menu option for all filetypes which is supposed to get the MD5 checksum for a file. HKEY_CLASSES_ROOT*\shell\Checksum - Default: Get Checksum and HKEY_CLASSES_ROOT*\shell\Checksum\command - Default: checksum.cmd "%1" checksum.cmd simply clears the screen, calls fciv.exe using %1 and then pauses. Unfortunately, whilst the option "Get Checksum" appears correctly in the right click menu, it doesn't perform the right action when clicked. When I click it an "Open With" dialog opens, which is of course not what I want. Both checksum.cmd and fciv.exe are in the PATH. checksum.cmd: @echo off cls fciv.exe %1 pause Anybody know what's going on?

  • How can I change shell in Ubuntu?

    - by Sanoj
    I have a Ubuntu Server VPS and I want to use /bin/bash/ as my shell. How can I change my shell? I have root access but I don't work as root. So dash is my default shell now. I have read How do I make Bash my default shell on Ubuntu? and chsh seams to be the preferred way to go. But when I type chsh /bin/bash I get this message: chsh: unknown user /bin/bash And if I just type /bin/bash the Bash shell seams to work fine. How to change it?

  • What kind of issues would occur if resolve.conf had no dns servers set?

    - by Stuart Woodward
    I want to create a server for a customer and have that customer finish the configuration for themselves. It was been decided that rather than setting default DNS servers (i.e. something like Google's) that the customer should enter the information by themselves. I assume that the customer is technically competent enough to do this. If however they forget or neglect to set this up they might spend some time trying to figure out what is wrong and eventually contact support. (In this case, I think that setting a default might have been better.) Apart from the obvious inability to resolve hosts, what other issues might they face until they have set valid dns servers in resolve.conf?

  • Booting off a ZFS root in 14.04

    - by RJVB
    I've been running a Debian derivative (LMDE) on a ZFS root for half a year now. It was created by cloning a regular ext4-based install with all the necessary packages onto a ZFS pool, chrooting into that pool and recreating a grub menu and bootloader. The system uses an ext-3 dedicated /boot partition. I would like to do the same with Ubuntu 14.04, but have encountered several obstacles. There is no Trusty zfs-grub package The default grub package doesn't have ZFS support built in. I found a small bug in the build system responsible for that (report with patch created) and built my own grub packages. The built-in ZFS support is dysfunctional, it does not add the proper arguments to the kernel command line I thus installed the ZoL grub package I also use on my LMDE system, which does give me a correct grub.cfg However, even with that correct grub.cfg, the boot process apparently doesn't retrieve the bootfs parameter from the ZFS pool; instead the variable that's supposed to receive the value remains empty. As a result, initrd tries to load the default pool ("rpool"), which fails of course. I can however import the pool by hand, and complete the process by hand. If memory serves me well, I also had to disable apparmor, to avoid the boot process from blocking after importing the pool. Am I overlooking something? Just for comparison, I installed the Ubuntu 3.13 kernel on my LMDE system, and that works just fine (i.e. the identical kernel and grub binaries allow successful booting without glitches on LMDE but not on Ubuntu).

  • Lotus Notes won't open a hyperlink/uri in a browser!

    - by Andy O
    I'm still new to Lotus, but I have LN 8.0.2, and have it set up to open hyperlinks "using the browser i have set as the default for this operating system" which in my case is Firefox 3.6.13. If I try to select "use the browser embedded in this client" then it just forgets it after I click save (ie if i go back into preferences it's reset to the default for this operating system option) Windows XP SP 3. Whenever I click on a link in an email...memo... then it does nothing and flashes an underscore underneath it. It's so basic and so annoying there must be something I'm missing. Any help please!

  • What are some ways of making manageable complex AI?

    - by Tetrad
    In the past I've used simple systems like finite state machines (FSMs) or hierarchical FSMs to control AI behavior. For any complex system, this pattern falls apart very quickly. I've heard about behavior trees and it seems like that's the next obvious step, but haven't seen a working implementation or really tried going down that route yet. Are there any other patterns to making manageable yet complex AI behaviors?

  • Documents stored on separate internal drive, Ubuntu doesn't notice on startup

    - by PlanoAlto
    My machine has Windows 7 Ultimate x64 and Ubuntu 12.04 LTS running side-by-side on a single hard drive with GRUB bootloader, each with 500 GB storage. I keep my personal documents on a separate 1TB hard drive so they remain isolated from any changes I make to the OS drive, but when Ubuntu starts it does not seem to notice my documents drive. While I've installed and worked with Ubuntu 12.04 Server x32 before, using it as a desktop OS is new to me. I use my documents drive for all of my personal data, including wallpapers and music, so it is imperative that Ubuntu recognize it on startup. Concerning the two specific examples: Ubuntu loads with the default blue-colored desktop instead of my desired picture of the spectacular Carina galaxy. When I right-click the desktop and select "Change Desktop Background", it wakes up from its amnesia and loads the proper background. As for my music, Rhythmbox defaults to an empty library upon reboot, forcing me to reload the settings manually each time. This gets quite tedious because I certainly can't work to my full potential without my music. The second thing I would like to address is making Ubuntu point the documents directories in ~ to their appropriate counterparts on the 1TB documents drive. I realize that this question is not new, but when I create the symbolical links, they established themselves inside the directories and did not convert the directories themselves into symbolical links. I also prefer not to move the files themselves from their current location on the 1TB drive. I believe this would also help the Rhythmbox library problem as well considering it's a default directory for the music player. Excerpt from fstab: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sdb6 during installation UUID=057ac83e-76ad-460d-86e5-b6d46e9b1d80 / ext4 errors=remount-ro 0 1 # swap was on /dev/sdb7 during installation #UUID=1183df90-23fc-44e4-aa17-4e7c9865d5cb none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 That's enough content for one question. I really like the Ubuntu experience so far since it doesn't treat me like an idiot out of the box (can't say the same for Windows) so I can't wait to hear from the community! Thanks for your help in advance.

  • How to run sudo command with no password?

    - by aychedee
    tl;dr: How does the ubuntu user on the AWS images for Ubuntu Server 12.04 have passwordless sudo for all commands when there is no configuration for it in `/etc/sudoers'? I'm using Ubuntu server 12.04 on Amazon. I want to add a new user that has the same behaviour as the default ubuntu user. Specifically I want passwordless sudo for this new user. So I've added a new user and went to edit /etc/sudoers (using visudo of course). From reading that file it seemed like the default ubuntu user was getting it's passwordless sudo from being a member of the admin group. So I added my new user to that. Which didn't work. Then I tried adding the NOPASSWD directive to sudoers. Which also didn't work. Anyway, now I'm just curious. How does the ubuntu user get passwordless privileges if they aren't defined in /etc/sudoers. What is the mechanism that allows this?

  • Catch and identify source of browser launch events

    - by beldaz
    My Windows XP computer is exhibiting strange behaviour, launching multiple browser windows, but not to any URL. Initially this was in Firefox, but when I uninstalled it the same happened in IE. Norton 360 detects no malware, and I wonder if there is some application that is accidentally causing the problem. I'd like to diagnose the problem further. It seems that the default browser is being launched by something, so I'd like to work out the culprit. Is there some method (or handy utility) that can catch requests to XP to launch the default browser, and identify the source?

  • How do I automatically start Clamz with AMZ files for Amazon MP3 downloads?

    - by Takkat
    Chromium can open downloaded files with the default application (e.g. PDF in Evince). In my setup a downloaded .AMZ (for Amazon MP3) always opened with Gedit. However I would like to have all downloaded .amz files to autromatically open with Clamz, a command line tool for downloading that works like a charm. As in Nautilus my .amz files were associated to open with Gedit too I thought it was a good idea to add a clamz.desktop file in ~/.local/share/applications (according to this answer) [Desktop Entry] Encoding=UTF-8 Name=Clamz Comment=Open AMZ files for Amazon MP3 download Exec=/usr/bin/clamz %u Terminal=True Type=Application Icon= Categories=Application; StartupNotify=true MimeType=audio/x-amzxml; NoDisplay=true This lets me choose Clamz as default application in Nautilus. But when opening an .amz file in Nautilus it still does not open with Clamz as expected but is treated as an executable text file instead (note that the executable bit is not set!). Is there any other way to make Chromium or Nautilus always open an .amz file with Clamz? Did I miss to change setting in another place?

  • Crackling sound from microphone recently, in 13.04

    - by Patrig Droumaguet
    I use 13.04 since the release and I use Skype which was working well. But recently I've had remarks saying my voice was "crackling", even if the voice from my interlocutor was perfect. Making a test with Audacity and Cheese, I've seen that every recorded sound (with the front microphone of my laptop or a jack microphone) was crackling. It's not really like saturating, the sound has a lot of annoying pops. I've tried to check the settings, they were still on PulseAudio. I've even tried the extreme solution : re-installing Ubuntu (because initially it was working)… with the same problem. If I boot on Windows (dual-boot) I have no problem (so it's not physical). If anyone could help :) My laptop is a HP dv6-6165sf. The sound card is a "IDT 92HD81B1X5" (with BeatsAudio). Thanks a lot ! New tests - july 6th Hi again, I've tried editing /etc/pulse/default.pa with these three settings : load-module module-udev-detect use_ucm=0 tsched=0 load-module module-udev-detect tsched=0 load-module module-udev-detect use_ucm=0 The three of them don't change anything, except the last one (which was by default) which makes Audacity record without any crackling sound. But in Skype, Cheese and Kazam, the sound is crackling… I've installed again Ubuntu 13.04 (from scratch, deleting everything from /home), and I've updated it. The microphone is still cracking. Thanks for your help !

  • Turn off write barriers on ext4 whiche FS is mounted

    - by user462982
    I am doing some IO intensive DB imports that run for several days now and the IO performance has dropped tremendously over times. The DB data files (log files) are on an ext4 formatted logical volume which is mounted with default options (did not specify something special in fstab). Since I just learned that ext4 enables write barriers by default: Q: Is there some way to disable write barriers online (i.e. while the file system is in use), because I cannot interrupt the import and don't want to restart it again. I am aware that write barriers might not be the only thing impeding performance it is a bad idea to have write barriers disabled on journalling file systems if data safty is important (e.g. on a production system)

  • Locale setting on a Red Hat box

    - by sasuke
    Hi all, Recently our organization got a couple of server boxes which are I guess present in some data-center in UK. The problem is that for some reason the default Locale representation in Java on that server returns en_US instead of the expected en_GB (I confirmed this by running a code on that server which simply outputs Locale.default()). I am pretty sure this has got something to do the way in which the boxes were set up. My question is: what would be the approach to fix this issue now that the OS has been installed? Is there any way I can for a given SSH session set the locale as en_GB instead of the current en_US? TIA, sasuke

  • A quick tip for those working with the Windows Phone 7 AD SDK.

    - by mbcrump
    One thing that I’ve noticed in several apps in the Windows Phone 7 marketplace is the ad chopping off on the right hand side. I decided that my next Windows Phone 7 app will be ad supported so why not sign up for the Advertising SDK and investigate this issue. *Note: If you want to see this in an actual app then download the free app called “Road Rage”. So here is an example of what I am talking about: You will notice that the right hand side of the AD is chopped off using the default ad banner. You can see the border on the left hand side clearly. So, what exactly is going on? Let’s take a look at this in the designer. From this image we can see it clearer, the margin of the grid that the ad is contained in needs to be removed. By default, the ContentPanel in a Windows Phone Page has a margin already set on it. See below for an example of this: <!--ContentPanel - place additional content here--> <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> </Grid> If you simply remove that margin then your ad will display properly as shown below. It’s strange that I’ve seen this in multiple WP7 applications in the marketplace. If you are trying to make money off Ads, you would probably want to make sure the full ad is displayed. I am hoping this short post helped someone.   Subscribe to my feed
