  • Loading zsh as the default shell in gnu screen

    - by joel
    Hello, Im using KUbuntu 10.04 (Lucid Lynx). I have installed zsh and screen. I have set zsh as the default shell, by setting Command to zsh in Settings-Edit Current Profile of the terminal. But,when i launch screen,the bash shell is loaded. If i run the command zsh, then zsh starts but the following message is displayed: "/home/joel/.zshrc:36: Can't add module parameter `mapfile': parameter already exists" Also,zsh is invoked for only the current screen instance and i have to invoke it manually again for other instances. So,is there any way to make screen load zsh by default and invoke it automatically for every instance ? Thank You

  • Opengl: fit a quad to screen, given the value of Z.

    - by hytparadisee
    Short Version of the question: I will put a quad. I know the width and height of the screen in window coordinates, i know the Z-coordinates of the quad in 3D. I know the FOVY, I know the aspect. The quad will be put along Z-axis, My camera doesn't move (placed at 0, 0, 0). I want to find out the width and height of the quad IN 3D COORDINATES that will fit exactly onto my screen. Long Version of the question: I would like to put a quad along the Z-axis at the specified offset Z, I would like to find out the width and height of the quad that will exactly fill the entire screen. I used to have a post on gamedev.net that uses a formula similar to the following: *dist = Z * tan ( FOV / 2 )* Now I can never find the post! Though it's similar, it is still different, because I remembered in that working formula, they do make use of screenWidth and screenHeight, which are the width and height of the screen in window coordinates. I am not really familiar with concepts like frustum, fov and aspect so that's why I can't work out the formula on my own. Besides, I am sure I don't need gluUnproject (I tried it, but the results are way off). It's not some gl calls, it's just a math formula that can find out the width and height in 3D space that can fill the entire screen, IF Z offset, width in window coordinates, and height in window coordinates, are known. Thanks all in advance.

  • Blackberry license screen agreement like Facebook

    - by Dachmt
    Hi, I have a "basic" license agreement screen for now, a Screen with a title set and vertical field containing a textfield, separatorfield and then 2 buttons (accept or decline). The license is pretty long, it's annoying going all the way down (except with the storm it's pretty easy) and I want a kind of popup screen showing the license and the 2 buttons at the bottom. To give you an example, the exact SAME as the Facebook or App World application's license screen agreement! When you scroll the text, it's going a lot faster and it's visualy great. Thank you!

  • How to draw to screen in c++ ?

    - by Kesarion
    How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised. Also, would it show up on a printscreen ? What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual. Here's an example: Let's say I want 2 yellow squares 5 by 5 pixels in size appearing in the center of the screen on top of all the other applications, unclickable and invisible to a printscreen.

  • Screen problems on 11.10 using VGA compatible controller 2nd Generation Core Processor Family Integrated Graphics Controller

    - by MorrisseyJ
    I am having problems with my display. The problem manifests as lots of screen artefacts, which seem to be worse in Unity than in Gnome 3, are worse after i have used suspend and are intolerable if i set myself up on a dual monitor. Specific issues include: icons disappearing, lines occurring all over the screen, the backgrounds of certain windows going another colour and window borders disappearing or being filled with text from other parts of the screen. The most annoying problem is lines of text disappearing from a host of word processing programmes (libreoffice, gedit, bluefish etc), as i type. In most circumstances the screen problem can be temporarily fixed (so that i can see the screen clearly) by either scrolling the text off the screen and then scrolling it back onto the screen, or highlighting the offending area of the desktop, by clicking and dragging. Errors on parts of the screen that don't seem to redraw (window borders (off the universal menu) or the screen area outside of a LO document, in print layout view, for example) can't seem to be fixed in a session. I am running 11.10, 64 bit on my Thinkpad x121e Display information is: description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:42 memory:d0000000-d03fffff memory:c0000000-cfffffff ioport:4000(size=64) There appear to be a few problems with the Intel graphics and Ubuntu but i am not sure if they are all the same. If anyone knows if this is a known bug it'd be great to know, otherwise i'll file a report. Should anyone know of a fix i would greatly appreciate hearing about it. Let me know if you need any more information. Thanks

  • Booting briefly shows CLI login and then black

    - by lepusfelix
    When I boot to Ubuntu on my dualboot system, it appears to boot normally, up to the point when I would normally expect to see the lightDM graphical login screen. However, I see a CLI login screen, which I assume is tty1. Before I get a chance to actually login to it, though, it drops to a black screen with a flashing cursor. Pressing ctrl+alt+f1 does nothing. When I hit the power button on the laptop, I see the usual scrolling text as Ubuntu shuts down. I know that this is related to me having installed the proprietary ATI drivers for the video card. Purging the drivers gave me back a GUI, but unfortunately no working desktop environment, and switching to the mesa drivers returned me to the black screen issue. The only way I can get a stable working CLI is through booting to advanced options and choosing a root shell prompt, as even the failsafe X session doesn't function for me.

  • loading splash screen takes priority over terminal or windows manager while running elsa

    - by schonjones
    I recently installed e17 and was trying to set up defaults to use elsa and ecomorph over the standard compiz as it constantly crashes since updating to 12.04. If elsa is installed the loading screen hangs and never loads to login, however i can get to a terminal or the e17 login instead of the standard gdm that usually shows up, within a second the screen goes back to the loading screen. I can still type and login as well as run commands in the terminal, but all I see is the loading screen. Switching between terminals i can confirm my commands before it switches back to the loading screen. If i remove elsa the loading screen hangs, but I can get to a terminal login and run lightdm to start my session with no problems. I have multiple DE installed and am unsure which loading screen is coming up. i think it's the KDE screen, grub comes up with a debian background if that helps. I'm not sure if i can switch the loading screen and resolve this issue or if i'm just going to have to scrap using elsa and get lightdm to load on boot again. Elsa would be my preference. I don't have the space to backup my files for a complete reinstall. Please help!

  • Problem: Black screen after resume

    - by Robert
    Problem: Black screen after resume I found the below statement that I provided the link for but, no instructions with it for a person that's new to Ubuntu on what exactly to do to fix the problem. Can someone clarify this for me? Thank you. Ubunu 13.10 AMD A6-3420M APU with Radeon(tm) HD Graphics × 4 64bit Toshiba L775 My computer boots to a black screen, what options do I have to fix it? Typical scenario is "use a laptop docked with lid closed, only the external screen is active, suspend, take the laptop, open it somewhere"... which leads to "no screen active". To debug this problem, check if gnome-settings-daemons is getting a signal that the display configuration has changed, by running xtrace against it, and look for a RRScreenChangeNotify event when resuming the machine. If that signal is being sent, then it indicates a possible bug in g-s-d. Otherwise, it suggests a bug in either X or (more likely) the kernel which is not causing the signal to be emitted to begin with.

  • Multi-screen and Nvidia GT220

    - by Bohors
    Excuse me first for my broken English I have 3 monitors on two Nvidia GT220. Unity 2D works fine after using the proprietary drivers. But no way to use compiz effects.

  • Windows 7 Dell 1545 rotate screen and change wallpaper

    - by bizarrechaos
    I recently bought a second monitor and hooked it to my laptop. I like to put the monitor in portrait mode when coding and i can do this with igfx but i was wondering if there was a way to make a keyboard shortcut that will rotate my display 270 degrees and change my wallpaper to one that fits the 1050 X 1680 portrait resolution, and then have a key that rotates back to normal and resets my wallpaper? I have googled to no avail, I look forward to your answers. Thanks in advance, bizarrechaos

  • A software to lock regions of a screen to prevent any windows from overlapping

    - by cybervaldez
    I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.

  • Lock Windows keyboard and mouse but still display screen normally

    - by Stephen Lacy
    I'm using windows 7, I have a dual monitor display. It displays important information related to the business, I'd rather that random users that walk in can't just walk over to it and start using the computer with the same access rights as the user the monitoring software is running as. What I would like is if any time someone presses a button on the keyboard including alt-ctrl-delete all that would appear is a dialog asking for a password. Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw

  • Hide a 2nd Monitor from a Programs Print Screen

    - by jasondavis
    I run 2 monitors on a PC that also runs a program for the Freelancing site Elance.com. The program they provide, takes screenshots and uploads them to my account for a client to see at different intervals. My goal is to make the screenshot that the program takes and uploads, to somehow only take a shot of my "Main" or "Defualt" monitor and ignore my 2nd monitor. The main reason is my 2nd monitor generally has private data that I do not displayed to the world on a website. Does anyone know if there is any kind of program or trick I can use that will make it appear that I have 1 monitor when a Screenshot is taken? I am not sure how the program does it and how that works as I am a web developer and not a C++ or any kind of low level programmer. If the Elance program simply runs the same function that is called when a PrintScreen key is pressed on a keyboard, then I am thinking it might be possible to maybe trick that into only the default desktop? Any ideas or help would be appreciated, thank you

  • Using external monitor and screen resolution?

    - by Johnydep
    it might sound very basic question but i need some help. I have lenovo Ideapad y560p which offers a maximum resolution of 1366px x 768px. Now i am planning to buy an external monitor, and i short listed some FULL HD resolution monitors, but it is my understanding that even with FULL HD, i would only achieve the best resolution my laptop supports. Is it true? And also if this is the case, should i really go for an HD monitor or settle down with a lower resolution version? 2ndly, is there any way to increase resolution with simple upgrade? or it is not possible without voiding the warranty??

  • Is there a way to force lubuntu screen resolution?

    - by za1
    I have a Dell Inspiron 4000, 900 Mhz Pentium III, 192 MB RAM,10.1 GB disk running Lubuntu 12.04. When I start the computer, and I check the display resolution, Monitor Settings claims that the max resolution is 1024x768. I then connected another monitor I had lying around, rebooted, and now the laptop monitor looks normal,and monitor settings claims that 1280x1024 is the max resolution (it is) and the other monitor doesn't turn on. (black screen) The external monitor is not broken. Is there a way to, without the external monitor, force the laptop monitor resolution to 1280x1024? (The following is another question) - How can you run commands automatically at startup? Specifically "xinput 18 118 0" (without quotes) The first question is important, I can live with typing the second one at every boot. Thanks

  • Ubuntu 14.04 stalling. Problem with LightDM. Plymouth (and logging out) switches over to a black screen w/ white cursor

    - by Kage
    if its a duplicate, sorry. Couldn't find anything that fits my issue, much less that was on 14.04. I changed a few things recently. Switched to the Numix theme (from PPA), installed lm-sensors and psensor (ran all the I/O probes), Ubuntu Tweak, Pinta, and well, Team Fortress 2 on Steam. :P The system will get to the Plymouth 'ubuntu' screen, load load, all dots filled, switches over to LightDM, but wait! No LightDM. :I Just a blank screen with that white cursor. Can't switch out to tty1-6 - not sure if the Ctrl-Alt-F1 is disabled in 14.04 or if its literally just locked down. If I change any files, I have access to the filesystem from my Windows 8 partition. That's it. :/ I'm pretty familiar with Linux, especially Ubuntu, but I think I'm still at the point I know just enough to break things and not always how to fix 'em. Any help would be greatly appreciated. Thanks! UPDATE I was just able to get into my desktop briefly. I booted Ubuntu. When the black screen froze, I hit Ctrl-Alt-Del. When it started switching off, I hit Ctrl-Alt-Backspace. It rebooted. I plugged the second monitor in I had been using before the issue ever came about. Plymouth displayed on both. LightDM came up, displayed on both (it used to show only the ubuntu logo on the unfocused monitor though). I logged in just fine. Even ran some pending software updates. I logged out of the desktop though, and LightDM refused to show again. xP
