  • 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.

  • Why do "ls" in UNIX and "dir" in DOS have different names?

    - by bizso09
    Why do they have different names for the same command, listing a directory? Surely, they could have talked to each other and agreed on one common name, such as for example cd which is the same for both unix and dos. This decision to have different names has created many headaches for developers and users and also increased incompatibility between the two systems. Did they do it on purpose? Then how come "cd" is the same?

  • 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.

  • High level command line program for burning CDs and DVDs?

    - by stickmangumby
    I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage. I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this: [program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ... It should then do all the low level copying and ISO generation transparently and just burn the damn disk! Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online. Thanks :)

  • 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?

  • 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?

  • 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.

  • Put Conky behind the desktop icons

    - by Michal Gow
    Maybe I am trying do something impossible, but after hours of Googling I didn't get 100% answer yet. So - it is possible put Conky on Desktop backgroud (behind desktop icons)? The usual config: own_window yes own_window_type normal # (desktop, override) - I have the same result for all this attributes own_window_transparent yes own_window_hints undecorated,below,skip_taskbar,sticky,skip_pager Is giving me Conky with (pseudo)transparent background in front of icons (they are completely hidden behind it, even if in background of Conky is shown background image), while I am trying achieve opposite... My system: SuSE 11.4 KDE 4.4 (Release 3) x86_64

    I was recently added to a group on the unix server. My active screen session has not been update to the new groups: $groups A B C D $screen -r $groups A B C Without closing my screen session is there a way for me to use my new privileges in the screen session? Or if not, is there at least a way I can save all of the different directories each of the tabs are on? Thanks, Dan

  • 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.

  • Auto-rotate rotated images with mogrify

    - by Frank Presencia Fandos
    Some of my images have been taken rotated but kept this data. The problem is that, when using mogrify to convert them from JPG to png, that data seems to dissapear. For showing this problem, I think the best is to show the script and an screenshot. Script with the code. Put it in a text file, give it execution permission, double click, run (from terminal if you wish) and wait a while. All the JPGs in that folder will be converted to png. #! /bin/bash echo "Converting JPG to png. Please don't close this window." mogrify -alpha on -format png *.JPG mogrify -alpha on -format -alpha on png *.jpg It works great and adds an alpha channel. This is personally useful when I edit them later, not to add the channel individually. Now the screenshot that illustrates the problem: As you can see, the original ones' (JPGs) preview is right, the modified preview is wrong, the Shotwell rendering is right and the GIMP edit is wrong and didn't even say the image was rotated, as it uses to do with other images. How can I edit my script to preserve the orientation?

  • 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?

  • Accidentally deleted /opt/local/bin without backup. Any help?

    - by Aaron
    Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

  • fstab line for auto mount drive that all users can read/write

    - by evilblender
    I have installed a cable that connects from the CPU's SATA motherboard connection to a removable drives' ESATA connection. I would like to be able to swap drives on the ESATA connection and have all users be able to read and write to these drives. I have created the directory /archive/ where I would like the drive(s) to mount. The drives are all formatted Fat 32 - but in the future I may use HFS for formatting. When I used the command (as root): mount /dev/sdc1 /archive the drive was mounted (but read only) What can I use in my /etc/fstab file that will allow drives to be mounted and unmounted by all users on the system? (both reading and writing) Also, will I be able to mount and unmount these drives without shutting down? or will I need to reboot every time I want to change drives? Thank you. Jeff

  • 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

  • Debian Testing installs Iceweasel ESR (severely outdated)?

    - by Lucas Phillips
    I just reinstalled Debian Testing, and for some reason, instead of Iceweasel 25, I have 17. The installed and candidate versions are both 17.0.9esr-1~deb7u1. apt-get update && apt-get upgrade does nothing, and it seems that version 17 is the latest for this install. I was on Debian Testing before, and Iceweasel was at the latest version. Even Debian Stable had an Iceweasel version 20. Why would it be trying to install ESR now?
