  • Ubuntu - No gnome-panels, no right-click, no internet, no hotkeys

    - by Darthfett
    Hey guys, I've been using Ubuntu (Maverick 10.10) on my desktop (ATI Radeon 5830) for about 3 weeks now, but all of a sudden I am unable to even use my computer. As soon as I start up, I see my desktop, with icons, but I don't see any gnome-panels, and I'm unable to get any options if I right-click. I can start programs by double clicking them. I also cannot get an internet connection. I've tried restarting gnome-panel by killing it, using Ctrl+Alt+5 to switch to a terminal (I don't have a shortcut to one on my desktop, and no hotkeys will work), but no luck. Restarting my computer has no effect upon this (I have to manually cut the power, since I don't know the terminal command). As far as I know, I have not made any changes, and I've never had any problems in the past. This started when I was playing Minecraft, but my internet crapped out, and no amount of re-trying the connection would work. I know it was my computer, as my brother's was working fine in the other room. Any clues as to what's going on? I'm more than willing to troubleshoot.

  • Forcing tar to create an empty archive

    - by snostorm
    I'm trying to use tar to tar files before transfer, so I can keep the entire file path rather than losing it along the way. However, when I try to tar an empty folder, it tells me that it is cowardly refusing to create an empty archive. I want to keep the empty folder on the other end, but don't want to put anything else into the archive to make it non-empty. Is there any way to do this?

  • Convert partition to Virtual Disk image

    - by Rick
    I have a 250 GB HD with a XP partition. I partitioned the XP Box to 112 GB, since the max Virtual PC can load is 127 GB. I have a new motherboard and can't load into the partition, so I am using Windows 7. I have tried using WinImage to create the image but it creates an image of the whole disc (250 GB) and will not load on Virtual PC cause of the size limit. What would be best to convert to VHD correctly?

  • How do ALSA and PulseAudio relate?

    - by Hanno Fietz
    While trying to get my sound to work, I was wondering about the roles of ALSA and PulseAudio. I have both installed and was wondering, for example, which of them needs to know about my sound card. Both seem to be able to use each other, there's a pulseaudio plugin for ALSA, and on my system, alsa shows up as a sound card in pulseaudio. Which of the two does what, are they alternatives or complementary?

  • Debian: Firefox or Iceweasel default printer for POS station

    - by Bubnoff
    Context Using Debian 6.04 "Squeeze" as POS station. There are two printers installed: Network printer and a receipt printer It absolutely must be able to print by default to the receipt printer on a certain website though the system default is a network printer. In Debian ...it doesn't. Problem I've set up XP, 7, Ubuntu and even Mac OSX this way, so I'm no stranger to setting Firefox up this way ...same Iceweasel/Firefox settings ...complete fail. Always uses system default no matter what the settings, or, which printer you print from. To get this to work on other systems you do this: Print a page in Firefox using desired printer. Ensure print.save_settings is true. Firefox remembers last printer used Set print.always_print_silent = true The end. This works on every OS I've set up ....except Firefox and Iceweasel in Debian. My only recourse seems to be to set the receipt printer as default or go back to bloaty Ubuntu/Mint ...etc.

  • How to tell if OpenGL is really working in Ubuntu 10.04

    - by Jonathan
    I have a lenovo S9e running Intel integrated graphics. Here is my lspci output related to the graphics: 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) Subsystem: Lenovo Device 3870 Flags: bus master, fast devsel, latency 0 Memory at f0580000 (32-bit, non-prefetchable) [size=512K] Capabilities: [d0] Power Management version 2 I want to know how I can make sure OpenGL support is running in full on an Ubuntu 10.04 installation. I have a few hints to think that it is not: The "Desktop Effects" will not load Apps such as stardock, when attempting to use OpenGL rendering, will display black boxes instead of transparency In the games Pioneers, the number-tile icons are suspiciously just black circles Windows games running with Wine will only support software rendering, not hardware rendering When I boot into a Knoppix LiveCD, the desktop effects do work, splendidly, meaning compiz detects my computer as capable. My problem with troubleshooting is that Canonical has basically eliminated the conf-file-based mechanism of X11 as far as I can tell, thus making it even harder to ensure graphics modules are loading properly. How do I debug and test OpenGL on m Ubuntu 10.04 installation?

  • Simulating mouse clicks at specific screen coordinates

    - by Matteo Riva
    I would like to be able to bind some keys to mouse clicks done in specific locations. For example: when I press F1 I should get a left mouse click at coordinates 300x350, F2 at 600x350 and so on. Even better if this could be bound to a specific window application so that coordinates could be relative to it instead of the base desktop. Is there a software which allows this? ADDITION: Ok autohotkey is great but I have problems with my particular setup. Quoting my comment below: I'm using it with an old game (championship manager 01/02) which runs in windowed mode (and I have to set win98 compatibility for it to run): I can get the mouse to move but no click goes to the application I have read this FAQ but it didn't help, this is the script I tried: SendMode Play SetKeyDelay, 0, 50, Play F1::Click 42, 191 F2::ControlSend ahk_class main, Click, Championship Manager 01/02 Still no luck: pointer moves but no click goes through.

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

  • convert full-disk RAID5 array to partition-based array?

    - by Delan Azabani
    I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care). Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

  • How to close all background processes in unix?

    - by Gabi Purcaru
    I have something like: cd project && python manage.py runserver & cd utilities && ./coffee_auto_compiler.py And I want both of them to close on Ctrl-C (or some other command). How can I accomplish that? EDIT: I tried using jobs -x kill and kill `jobs -p `, but it doesn't seem to kill what I need. Here is what I mean: moon 8119 0.0 0.0 7556 3008 pts/0 S 13:17 0:00 /bin/bash moon 8120 6.8 0.4 24568 18928 pts/0 S 13:17 0:00 python manage.py runserver jobs -p give me just process 8119, but I also need to close 8120, since it's the thing that the first command opened. If it helps, the commands are actually in a Makefile, and I want it to run two daemons at the same time (and somehow close them at the same time). And yes, I'm using ubuntu, with bash

  • Connect a ssd externally such that hdparm is fully supported

    - by student
    I am just trying some hdparm magic with my new ssd (samsung 840 pro). However I don't want to change my drive over and over so it would be great if I could connect it externally to my laptop. I have a cheap sata-usb Adapter, but I feel it doesn't support the ATA commands send by hdparm. So what's the best way to do this? Are there sata-usb Adapters which fully support the hdparm things? Would it be a good idea to buy a sata-esata adapter to get full control over the drive?

  • How to add delay in autologin

    - by raj
    I enabled autologin in my system (CentOS 6.2) for that I edited this file /etc/gdm/custom.conf In that I entered this code [daemon] AutomaticLoginEnable=true AutomaticLogin=test Here test means one account name, for that account autologin is working but the problem is not possible to logout. That is because everytime while I logout it will go to gdm(graphical display manager) and there it Again checks for account test. It is available right so it will again login to same account. Here I want add delay, that means it should wait for sometime, If no one login to any other account, then only test account will log. how to add delay?

  • Taking a screencast in Backtrack 4

    - by user30196
    I'm working on a tutorial using Backtrack 4 Live USB, and I would like to take a screencast of what I'm doing (not just screenshots) So far I have tried these application with limited success: -recordmydesktop -xvidcap -wink -istanbul -vlc -vnc2flv Each time I try the resulting files are generally choppy (at best 1 frame per second) and most don't even end up with a clear view of the screen each time. If anyone has suggestions for the screencast I would greatly appreciate it.

  • How can I fix Problems with interlaced video jerking/flicking when playedback on DVD players? (Mixin

    - by Simon P Stevens
    I'm trying to make a DVD and the final DVD jerks when played on standalone DVD players. It seems to play fine on PCs. I think the problem may be to do with interlacing settings when rendering the final output, but I'll outline the whole editing process I have followed in case I've made a mistake somewhere else. Most of the footage comes from a sony handy cam (one of those mini DVD ones) so isn't great quality. It was set to "high quality" (haha) and 16:9 aspect ratio when it was recorded. I copy the files directly from the mini DVDs onto the hard drive and import them into Cinelerra. In Cinelerra I set the format to 25fps, 720x576, RGBA-8bit, 16:9, interlaced bottom fields first. When I've finished the editing, I add a Fields to frames effect (set to bottom first) to each video track. I render to audio and video separately: Audio: AC3, 128kbps Video: YUV4MPEG steam, video pipe settings: ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct mpeg2video % Cinelerra often crashes during the rendering, so I set it to generate a new video file at each label, and combine them using cat when I've got a sucesful render of each one. Once I've combined them, I use mencoder to re-index them: mencoder -forceidx -oac copy -ovc copy merged.m2v -o mergedReIndexed.m2v I combine the audio and video files using ffmpeg: ffmpeg -i AudioFile.ac3 -i VideoFile.m2v -target dvd -flags +ilme+ildct FinalMovie.mpg Then I build the menus with spumux and I create the DVD file system with dvdauthor, and finally I write it do a dvd-r like this: nice -n -20 growisofs -dvd-compat -speed=2 -Z /dev/dvd -dvd-video -V VIDEO ./ && eject /dev/dvd Originally, when I did it the DVD flickered badly, so as suggested in a guide I added the fields to frames effect in cinelerra. Now it doesn't "flicker", but has become "jerky" when there is lots of motion, particularly when the camera is moving, so the whole background moves. This is what I've tried so far: Removed "mpeg2video" from cinelerra video render pipe. Removed +ilme from render pipe. Removed +ildct from render pipe. Removed +ilme from render audio/video rejoin command. Removed +ildct from render audio/video rejoin command. Added -alt to render pipe. Added -alt to render audio/video rejoin command. Tried with and without the frames to fields effect in Cinelerra. and various combinations of the above. I've also tried this: change the Cinelerra fps to 50, use fields to frames (instead of frames to fields), render to an intermediate QTforlinux jpeg video stream, re-importing that back into Cinelerra, adding a frames to fields effect and then rendering that output as normal (@25fps), and I still have the same problem. Has anyone experienced this "jerking" playback before? Can anyone give any suggestions on how to fix it? (Like I say, it plays back fine on a PC, but not on any of the standalone players I've tried)
