  • Detach current session and attach to another session, done with one script, can I?

    - by Jimm Chen
    After reading the vague official doc of GNU screen( http://www.gnu.org/software/screen/manual/screen.html ) and asking quite some questions at this site. I still cannot figure out how to accomplish such a task with a shell script. This task costs some words to describe. Assume I'm using PuTTY to telnet into my Linux server. ?STEP 1? Launch 2 telnet connections . From putty window 1 (PTWIN1),telnet into Linux Bash shell, execute screen -RR to launch a screen session, and get session name 21385.pts-4.linux-ic37 . From putty window 2 (PTWIN2), do that same as in PTWIN1, but this time, I get session name 22041.pts-9.linux-ic37 . Now, we have two screen sessions running simultaneously. We can check this: $ screen -ls There are screens on: 22041.pts-9.linux-ic37 (Attached) 21385.pts-4.linux-ic37 (Attached) 2 Sockets in /var/run/uscreens/S-chj2. ?STEP 2? Assume that for some reason, PTWIN1's TCP connection is lost abnormally(but server doesn't know that), and an urgent work is pending on session 21385 and I want to quickly regain control of it. Fortunately, we know the 21385 session is still there, so, I want to have PTWIN2 attach to session 21385. Because I hate to remember the esoteric screen option all the time, so I decide to write a script called sttach. I hope that sttach 21385.pts-4.linux-ic37 can let me attach to session 21385(for PTWIN2). Now, let's say sttach works well and I take control of 21385 on PTWIN2. ?STEP 3? Some minutes later. I want to go back to work on session 22041. Here, please allow me to have PTWIN2 remain associated with session 21385. What I would like to do is to launch another putty window (PTWIN3), telnet into server, and execute sttach 22041.pts-9.linux-ic37 in hope that I can resume session 22041 on PTWIN3 . You can see the benefit of sttach: as long as I know the target session name, I can call it to have my PuTTY window switch to that session, regardless whether the target session is "(Attached)" or "(Detached)", and regardless whether the running context is inside a screen session or not. Now the question: How to write the (Bash) script sttach? I mean, run screen with appropriate options in sttach to accomplish the goal. Waiting for your kind answer. Thank you. My previous questions regarding GNU screen: GNU screen, how to get current sessionname programmatically Is it possible to change GNU screen session name after created? How do I know I'm running inside a linux "screen" or not? My env: openSUSE Linux 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

  • Alt+Tab doesn't work when Citrix is in full screen

    - by porec
    I am using 12.04 and in my work we connect to a Citrix XenDesktop. I've installed Citrix Receiver, using this link and it all works perfectly. But, I have a problem. Alt+Tab doesn't work in full screen mode. There are several adjustments you can choose when login in, with the Settings "button" up in the right corner. (Sorry, I couldn't post an image because I'm new.) I like to work with 95% full screen, with the windows key combination in "full screen mode only". This allows me to use the windows combinations when a work in full screen, inside the remote computer (inside Citrix). I can Alt+Tab past the "Citrix computer" when I put it down to 95%. It also allows me to use the "Ubuntu menu" on the left side. But I really can't make this work in Ubuntu. I've tried to put the windows key combination to "remote server only" and yes, it works inside the server, but also only there and the Ubuntu menu stops working. (in example print Screen. I am using this for documentation.) When I try to Tab from one place to another, even when Citrix isn't in full mode, if I stop there and the continue "tabbing" it continues inside Citrix. I want to use windows key combination, but only in full screen mode. Does anyone have a solution to fix in another way?

  • Blank screen after GRUB (64 bit) - cannot install Ubuntu

    - by peGGi
    My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

  • Slick 2d scrolling off screen

    - by Peter
    I have something scrolling in and out of the screen. Now when it goes off screen, I want it to scroll into the screen at another location. What I do is I grab the last pixels at the screens edge using g.copyArea and then g.drawImage on the edge of the screen. And then I do a g.translate to create room for the next row which is next render cycle. My problem is that I get a single pixel row, which is not copied onto the canvas. Where as I want each row to be added and then translated, so that the image that scrolled off screen is recreated on the other side of the screen. Here is my code, maybe there is a better way of doing this, open to any suggests, cause I'm totally stuck @Override public void render(GameContainer gc, Graphics g) throws SlickException { //g.setClip(0, 0, 300, gc.getHeight()); g.translate(0, y); g.drawImage(image,0,200); g.resetTransform(); //g.clearClip(); g.copyArea(rightImage, 0, gc.getHeight() - 1); g.drawImage(rightImage, 300, 0); g.translate(0, y); y=y+3; }

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • How do you disable the Windows Phone 7 splash screen?

    - by Zain
    Hi, Is there any way to disable the WP7 splash screen and just show a blank screen? My splash screen only stays on for less than half a second, leaving the user with a rather jarring sensation. I'd rather they not see any splash screen at all. I would have simply used a plain black image as my splash screen, but then that would result in an ugly experience for people using a light theme (since my app's background is white on light themes and black on dark themes) Thanks!

  • How to update off screen bitmap in a surfaceview thread

    - by DKDiveDude
    I have a Surfaceview thread and an off canvas texture bitmap that is being generated (changed), first row (line), every frame and then copied one position (line) down on regular surfaceview bitmap to make a scrolling effect, and I then continue to draw other things on top of that. Well that is what I really want, however I can't get it to work even though I am creating a separate canvas for off screen bitmap. It is just not scrolling at all. I other words I have a memory bitmap, same size as Surfaceview canvas, which I need to scroll (shift) down one line every frame, and then replace top line with new random texture, and then draw that on regular Surfaceview canvas. Here is what I thought would work; My surfaceChanged where I specify bitmap and canvasses and start thread: @Override public void surfaceCreated(SurfaceHolder holder) { intSurfaceWidth = mSurfaceView.getWidth(); intSurfaceHeight = mSurfaceView.getHeight(); memBitmap = Bitmap.createBitmap(intSurfaceWidth, intSurfaceHeight, Bitmap.Config.ARGB_8888); memCanvas = new Canvas(memCanvas); myThread = new MyThread(holder, this); myThread.setRunning(true); blnPause = false; myThread.start(); } My thread, only showing essential middle running part: @Override public void run() { while (running) { c = null; try { // Lock canvas for drawing c = myHolder.lockCanvas(null); synchronized (mSurfaceHolder) { // First draw off screen bitmap to off screen canvas one line down memCanvas.drawBitmap(memBitmap, 0, 1, null); // Create random one line(row) texture bitmap memTexture = Bitmap.createBitmap(imgTexture, 0, rnd.nextInt(intTextureImageHeight), intSurfaceWidth, 1); // Now add this texture bitmap to top of off screen canvas and hopefully bitmap memCanvas.drawBitmap(textureBitmap, intSurfaceWidth, 0, null); // Draw above updated off screen bitmap to regular canvas, at least I thought it would update (save changes) shifting down and add the texture line to off screen bitmap the off screen canvas was pointing to. c.drawBitmap(memBitmap, 0, 0, null); // Other drawing to canvas comes here } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { myHolder.unlockCanvasAndPost(c); } } } } For my game Tunnel Run. Right now I have a working solution where I instead have an array of bitmaps, size of surface height, that I populate with my random texture and then shift down in a loop for each frame. I get 50 frames per second, but I think I can do better by instead scrolling bitmap.

  • Cinnamon Settings blank after update

    - by Seth Balmore
    Using Ubuntu 12.04 with the cinnamon desktop, I installed the most recent updates and now when I open "System Settings" the entire window appears as a blank white screen. The headers for APPEARANCE, PREFERENCES, and HARDWARE are present, but the usual icons for *Background, *Hot Corners, *Printers, etc. are no longer visible. Some of these settings can still be altered via the terminal: cinnamon-settings backgrounds cinnamon-settings applets cinnamon-settings mouse and touchpad But other commands, such as cinnamon-settings hot corners are met with an error. This is obviously a problem with cinnamon, so I just want to bring it to attention and find out when they plan on fixing the bug. A workaround can be found on the web, but it seems way to risky to rely on.

  • Crontab opens as blank page, cannot save

    - by Sarah
    I am really not familiar with linux, and only started using it recently, so be patient with me. I am trying to control a camera on regular intervals through a script that is called upon in the crontab. When I start up the computer, I can open crontab, edit and save, and everything is executed correctly. However, I can never open crontab a second time, unless I restart the computer first. If I type crontab -e, I get a blank page, located in the /tmp directory. I can enter my commands in there, but cannot save it. I don't know if this is relevant, but when I try sudo crontab -e, I get something like "no cron installed for root". Any help is really appreciated! Sarah

  • Bluetooth not working and terminal has no command line, just a blank screen Ubuntu 12.04

    - by Josh
    I recently upgraded to 12.04 from 11.10 (ironically 11.10 had everything working, it was just laggy and jittery - now stuff isn't working on 12.04). I plug in my bluetooth dongle and the bluetooth symbol appears in the status bar top right, I can "Turn on bluetooth" and "Turn off bluetooth" here, but it has no effect overall on the status of bluetooth. When I go to Bluetooth settings I can't make it turn on. Also, as I have now discovered, my terminal has no command line for me to do anything with. There is absolutely nothing there... just a black, blank screen... Help?!

  • after login, the desktop remains blank.

    - by MobileDev123
    Hi, I have installed Ubuntu 10 last night and finished all upgrading stuff, in the time when updates are applied I downloaded a torrent file. As soon as download is finished I rebooted my system. As usual at start up it asked my login and I did the same. After a successful login It should show me the desktop, or show an error message in case anything has gone wrong. But what I had is only a cursor and a blank wall paper. Can anybody tell me what is the problem and how to resolve this? Thanks

  • Blank desktop after login

    - by Alex
    Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen. I have tried everything I could think about including Reinstalled compiz, unity, ubuntu-desktop, xorg Reinstalled and then removed the nvidia driver So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all. I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work. Does anybody know what else I could try? UPDATE: sudo dpkg-reconfigure xserver-xorg sudo service lightdm stop sudo service lightdm start When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there. Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY I can only run applications with export DISPLAY=:0

  • Blank lines between sourcecode [closed]

    - by manix
    I'm so confused with a strange behaviour. Actually I have edited some php files remotely with my PhpDesigner8 (a php editor). Everything goes right, but when my teammates reopen the files that I have edited the source code have blank lines like below: class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Instead of class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Did you have experience these kinds of problems?

  • A good web data extraction/screen scraper program?

    - by Taylor
    I need to capture product data from a site on a regular basis and wondered if any one knows of a good software program? I've trialed Mozenda but its a monthly subscription and pricey in the long term. Obviously something thats free would be best but I don't mind paying either. Just need a decent program thats reliable and doesn't require much programming knowledge.

  • Screen scrape a web page that uses javaScript and frames

    - by Mello
    Hi, I want to scrape data from www.marktplaats.nl . I want to analyze the scraped description, price, date and views in Excel/Access. I tried to scrape data with Ruby (nokogiri, scrapi) but nothing worked. (on other sites it worked well) The main problem is that for example selectorgadget and the add-on firebug (Firefox) don’t find any css I can use to scrape the page. On other sites I can extract the css with selectorgadget or firebug and use it with nokogiri or scrapi. Due to lack of experience it is difficult to identify the problem and therefore searching for a solution isn’t easy. Can you tell me where to start solving this problem and where I maybe can find more info about a similar scraping process? Thanks in advance!

  • Capturing WPF Vector Information BEFORE it Renders to Screen

    - by user273722
    I'm trying to "capture" or record the vector display information of a WPF (maybe Silverlight) application and play it back. However, instead of capturing bitmaps of what is rendered, I would like to capture the vector information BEFORE it gets rendered so that I can play it back at different resolutions without loss of quality. Ideally, I'd like to do this without having to add assemblies into my app (but willing to do so if necessary). I've looked into the WPF rendering pipeline and cannot find an appropriate starting point (or, stated differently, I couldn't figure it out). Maybe the VisualTreeHelper class?

  • android drawable changes sizes on screen when reading image from file

    - by Daniel Benedykt
    Hi I have an image on a private file. I read the file, create the drawable, and assign it to an ImageView. The ImageView has WRAP_CONTENT so the size is automatic. On 320x480 screens, the image looks good But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100. Of course it has something to do with the density but not sure how should I resolve this. This is my code: FileInputStream fis = this.openFileInput("icon.png"); icon = Drawable.createFromStream(fis, "icon"); fis.close(); imageView.setImageDrawable(icon); thanks
