  • 10.10 boots to command line login prompt

    - by greggory.hz
    I recently installed Ubuntu 10.10 on a computer that was previously running 10.04 (that worked fine). Now, each time I boot up, it starts up in a command line login prompt. I can login and it stays at the command line (as expected). I can then manually start gdm with sudo start gdm and it works fine. I can also enable compiz (using proprietary nvidia drivers) so I'm reasonably confident that it's not a driver problem (at least not in the sense that the drivers just flat out aren't working). Interestingly, if I leave it at the command prompt without logging in, after about 5 or 10 minutes, gnome starts up on its own. I'm not sure what is causing this. This is what dmesg | tail gives me after a manual start of gdm: [ 15.664166] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 270.18 Tue Jan 18 21:46:26 PST 2011 [ 15.991304] type=1400 audit(1297543976.953:11): apparmor="STATUS" operation="profile_load" name="/usr/share/gdm/guest-session/Xsession" pid=990 comm="apparmor_parser" [ 16.606986] eth0: link up, 100Mbps, full-duplex, lpa 0xCDE1 [ 18.798506] EXT4-fs (sda1): re-mounted.

  • I cannot login into any TTYs

    - by Lucio
    My system is Ubuntu 11.10. When I enter into any tty (1, 2, 3..) it ask me my login name and password but I can not move forward. It say that the info isn't correct. I have a user without password called world, so I enter world but it show me this Module invalid (or similar) The problems is that I must enter a command and I can't. There isn't any way to fix or an alternative way to enter the command?

  • jpegexiforient does not seem to work in 12.04

    - by Pointy
    In Ubuntu 12.04, the jpegexiforient command doesn't seem to work. I've got a .jpg file for which exif clearly shows (correct) EXIF orientation information, but running jpegexiforient on the file returns nothing. I don't particularly care about that command, but it makes exifautotran not work. I could (and might) rewrite that script to use exif instead, but I'm just wondering if there's something dumb I'm just doing wrong. I found this somewhat old bug report but its suggestion of running exif to update the setting didn't make any difference. Does jpegexiforient work for anybody?

  • After the update today no graphical interface anymore - 12.04

    - by Mark
    I installed the updates through the update manager today. I shut down my Laptop and now after starting it up again, I only get terminal access to advices. Grub is loading fine and after I picked Ubuntu 12.04 the screen get blank and I am asked to log in with my username and password in command line mode. If I log in I am still in command line mode. How do I get the "normal (graphical)" Ubuntu back? I hope you know what I mean. Since English is not my first language I can't explain this the way I would like to. Mark

    - by Alex
    im trying to do this tutorial: http://wiki.accelereyes.com/wiki/index.php/Installing_CUDA_Under_Ubuntu_10.04 I need the command that would completely stop/turn off the x-server. when i try to install the nvidia developer driver, i get a blue screen telling my Error:cant install with x-server running, please turn it off (something like that).

  • Space (and pipe sign) works on occasion only

  • How to make in CLI check for updates to be happening every 4 weeks and install them automatically without going to Software sources?

    - by Kangarooo
    I have a set of custom commands I run on my computers after I install them. How do I make Ubuntu check for updates every 4 weeks and install them automatically on check? I would need this done via command line so I can set it up for usual users when I set up their computers. The first command will make the update manager check for updates every 2 weeks because they not always come so much and to save the bandwidth of the Ubuntu servers. I also need to set it so that users don't need to click to install updates since it's tiring every time I help a friend set up a computer.

  • How do I get "ruby" to do what "ruby1.9.1" does?

    - by Daniel
    I want to start off by saying... I really don't need to be using 1.9.2. I understand that you don't ever, ever use Python 3.2, so if the common advice is that I should use 1.8, I'll do that. But don't tell me to do that because it's easier. Whatever version I should be using, though, the question is still relevant: What's a good way to make one command do another command? (I suppose I could write a c program to launch ruby1.9.1, call the executable ruby, and put it in my bin, but this seems like less than a good idea)

  • Trouble installing downloaded program

    - by Hamlette
    I purchased and downloaded Celtx and I'm having trouble installing it (in Ubuntu 13.04). I'm a Linux newbie (literally had it for four days) so please be kind and don't assume much experience with the command line, I'm still learning. The folder with all related files/packages etc. is under "Downloads" and I have tried several commands to try and install but I'm just not doing it right and would appreciate help with exactly what command(s) to use. Sudo apt-get install celtx did not work. I'm assuming I'm missing a step somewhere.

  • Quick path jumping

    - by Sebastian P.
    I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

  • Coherence Query Performance in Large Clusters

    - by jpurdy
    Large clusters (measured in terms of the number of storage-enabled members participating in the largest cache services) may introduce challenges when issuing queries. There is no particular cluster size threshold for this, rather a gradually increasing tendency for issues to arise. The most obvious challenges are that a client's perceived query latency will be determined by the slowest responder (more likely to be a factor in larger clusters) as well as the fact that adding additional cache servers will not increase query throughput if the query processing is not compute-bound (which would generally be the case for most indexed queries). If the data set can take advantage of the partition affinity features of Coherence, then the application can use a PartitionedFilter to target a query to a single server (using partition affinity to ensure that all data is in a single partition). If this can not be done, then avoiding an excessive number of cache server JVMs will help, as will ensuring that each cache server has sufficient CPU resources available and is also properly configured to minimize GC pauses (the most common cause of a slow-responding cache server).

  • Ubuntu 12.04LTS loads straight to terminal!! startx doesn't work!

    - by user293256
    I have been using ubuntu 12.04LTS for last few months, and now suddenly something has happened to it. As a result, terminal opens on every start up when I login . Although, if i login as a guest, it works fine. I have already used startx command, and tried reinstalling the desktop as well but it doesn't work! If I use ctrl+alt+f9, terminal screen vanishes and a black screen appears, and then nothing happens after that. ctrl+alt+f1 takes me to the command prompt. I know similar questions have been asked here, but i could not find a solution for my laptop. Please help!!

What I need is a command line which close the network and don't mess with Network Manager, maybe with the routing table or what else.

  • No GUI before login on Ubuntu 14.04

    - by Pablo Chinchilla
    After I installed Ubuntu 14.04 as the only OS on my computer on nomodeset to install the Nvidia drivers for my video card. I installed it and all is working properly. The only problem that I have is that when I turn on my compurter I only see command lines instead of the Ubuntu logo. After that the login screen works in a proper way even with the GUI. I only want to get the Ubuntu logo instead of the command lines. PS: when I turn off my computer, the same thing is repeated.

  • Update to 13.10 without GUI access

    - by Tom
    After upgrading 13.04 with the latest patches, I'm getting some really weird problems -- namely, logging in at the GUI just dumps me back at the GUI login screen. I can, however, get command line access from Ctrl-Alt-F1, and remotely via SSH. Given that I was doing these updates to step to 13.10, I figure I might as well continue the process, and then deal with the fallout once I get there. However, how can this be achieved with only the command line, and no X available? The only method I've found thus far is to run 'update-manager', which does not appear to have a CLI mode (and will not start without access to X). What's the solution? Thanks!

  • 12.04 Booting into Terminal

    - by user170796
    To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

  • How to create a new LaTeX command that behaves something like \verb?

    - by NawaMan
    I have been using LaTeX from sometime now, but have never actually gotten my hands dirty declaring a new command, as I try to avoid that. However, I need to add monospace text often in my document and I use \verb for it which is fine, except that the verb font size is bigger than the normal text font. So I need to change the font size and undo done like \small{}\verb#My monospace code#\normalsize{}. This is not very convenient and mistake-prone. Is there a better way to do this? Can I define a new command for this? How?

  • How to execute a command from with in MSI?

    Hi, I have a installation setup with works like this: /exec.exe /some-command This whole setup is located on a shared disk to which my target machine have access to. All i want is to create a small MSI wrapper that basically executes the above command. I don't need to any other fancy things? I looked up on the web; there are tools that create MSI for you but they generate huge amount of other things with them as well. My need is very simple and straight forward. It would be great if some could help me with this issue. Thanks, Omer

  • How can I choose different hints for different joins for a single table in a query hint?

    - by RenderIn
    Suppose I have the following query: select * from A, B, C, D where A.x = B.x and B.y = C.y and A.z = D.z I have indexes on A.x and B.x and B.y and C.y and D.z There is no index on A.z. How can I give a hint to this query to use an INDEX hint on A.x but a USE_HASH hint on A.z? It seems like hints only take the table name, not the specific join, so when using a single table with multiple joins I can only specify a single strategy for all of them. Alternative, suppose I'm using a LEADING or ORDERED hint on the above query. Both of these hints only take a table name as well, so how can I ensure that the A.x = B.x join takes place before the A.z = D.z one? I realize in this case I could list D first, but imagine D subsequently joins to E and that the D-E join is the last one I want in the entire query. A third configuration -- Suppose I want the A.x join to be the first of the entire query, and I want the A.z join to be the last one. How can I use a hint to have a single join from A to take place, followed by the B-C join, and the A-D join last?

  • will a mysql query run slower if one of the tables involved has no index defined??

    - by lock
    there's this already populated database which came from another dev im not sure what went on that dev's mind when he created the tables, but on one of our scripts there is this query involving 4 tables and it runs super slow SELECT a.col_1, a.col_2, a.col_3, a.col_4, a.col_5, a.col_6, a.col_7 FROM a, b, c, d WHERE a.id = b.id AND b.c_id = c.id AND c.id = d.c_id AND a.col_8 = '$col_8' AND d.g_id = '$g_id' AND c.private = '1' NOTE: $col_8 and $g_id are variables from a form its only my theory that it's due to tables b and c not having an index, although im guessing that the dev didnt think that it was necessary since those tables only tell relations between a and d, where b tells that the data in a belongs to a certain user, and c tells that the user belongs to a group in d as you can see, there's not even a join or other extensive query functions used but this query which returns only around 100 rows takes 2 minutes to execute. anyway my question is simply this post's title. will a mysql query run slower if one of the tables involved has no index defined??
