  • Why does 12.04 freeze when using multiple desktops?

    - by Dustin
    I am using 12.04 32-bit, upgraded from 11.10. Within the last week and a half Unity has hung on me with no option but a hard reboot, which I hate. It usually happens when I am using multiple desktops and applications and switching desktops. The screen just hangs, sometimes broken between desktops and applications, I can move my mouse but cannot click on anything. alt+f2 , HUD , super+w/s/d and alt+tab/~ does nothing, they do not activate. I let it rest for 15-20 minutes in hopes it will sort itself out but nothing. I'd hate to move to Unity 2D, but I can't risk having to do hard reboots/shutdowns, or moving to a different DE. Other information: the only PPA's I have added recently would be the word lens. 2.8GB RAM processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 127 model name : AMD Sempron(tm) Processor LE-1250 stepping : 2 microcode : 0x83 cpu MHz : 1000.000

  • Hotkey to shut down from login screen?

    - by Skizz
    I used to run 9.04 on my server and used to be able to use Alt-T, Alt-S to shut the system down from the login screen. It was using a KDE login screen. Now I've upgraded to 10.04 and use the Gnome login screen and I can't see any keyboard shortcuts to shutdown the server. Is there a shortcut and if so, what is it? Further info - I would normally shut down the server without turning on the monitor, which was easy using the keyboard shortcuts. Doing it with a mouse is not so easy without the monitor being on.

  • Kernel freezes with nvidia optimus and bumblebee on 12.04

    - by piovisqui
    I have a Sony VAIO with Intel i7-3520M and NVIDIA Corporation GK107M [GeForce GT 640M LE]. I installed bumblebee and nvidia drivers. They work almost fine, but the system freezes like in a kernel panic once every day. I can play Dota 2 with primusrun on it with 20-30fps 1080p. But when I do something simple as expanding the KDE calendar widget from the bottom right corner, the system hangs a lot and windows borders get another border. The system freezes in not very intensive graphic tasks, for instance, ALT+TAB with KWin effects or pressing ALT+F2 for poping up the launcher. How can I solve this? Info: I use KDE. Couldn't paste de logs here, check at pastebin: http://pastebin.com/SBet8fRQ

  • Why can we delete some built-in properties of global object?

    - by demix
    I'm reading es5 these days and find that [[configurable]] attribute in some built-in properties of global object is set to true which means we can delete these properties. For example: the join method of Array.prototype object have attributes {[[Writable]]:true, [[Enumerable]]: false, [[Configurable]]: true} So we can easily delete the join method for Array like: delete Array.prototype.join; alert([1,2,3].join); The alert will display undefined in my chromium 17,firefox 9 ,ie 10,even ie6; In Chrome 15 & safari 5.1.1 the [[configurable]] attribute is set to true and delete result is also true but the final result is still function(){[native code]}. Seems like this is a bug and chromium fix it. I haven't notice that before. In my opinion, delete built-in functions in user's code is dangerous, and will bring out so many bugs when working with others.So why ECMAScript make this decision?

  • Oracle Communications Calendar Server: Upgrading to Version 7 Update 3

    - by joesciallo
    It's been some time since I have posted an entry. Now, with the release of Oracle Communications Calendar Server 7 Update 3, it seems high time to jump start this blog again. To begin with, check out what's new in this release: Authenticating Against an External Directory Booking Window for Calendars Changes to the davadmin Command Enable and Disable Account Autocreation LDAP Pools New Configuration Parameters New Languages New populate-davuniqueid Utility New Schema Objects Non-active Calendar Accounts Are No Longer Searched or Fetched Remote Document Store Authentication The upgrade is a bit more complicated than normal, as you must first apply some new schema elements to your Directory Server(s). To do so, you need to get the comm_dssetup 6.4 patch, patch the comm_dssetup script, and then run the patched comm_dssetup against your Directory Server(s) instances. In addition, if you are using the nsUniqueId attribute as your deployment's unique identifier, you'll want to change that to the new davUniqueId attribute. Consult the Upgrade Procedure for details, as well as DaBrain's blog, before forging ahead with this upgrade. Additional quick links: Problems Fixed in This Release Known Issues Calendar Server Unique Identifier Changes to the davadmin command Get the Calendar Server patch Get the comm_dssetup patch

  • How can i change focus when game locks it?

    - by GrizzLy
    I am playing wolfenstein:enemy territory, and if i play it in windowed mode, i can't change focus from game to something else (alt+tab doesnt work). EDIT1: As far as i could try, only ctrl+alt+Fx works (x is one number, for example F1 will switch to terminal). Could i somehow capture this kind of shortcut somewhere on X level and then send it to compiz to change focus (minimize currently focused window)? EDIT2: I found one other way, it works for Wolf:ET, it may help with other games too, if you turn on gameconsole (usually tilde key) game will release mouse lock (in windowed mode).

  • How can I switch between windows of the same application?

    - by dennis2008
    I often have more than ten windows open at the same time and some of them are of the same applications, notably gnome-terminal. Often when I am currently on one terminal, I just want to get to another terminal. With Alt-Tab you have to choose from windows of all the applications, which is a pain. Even with Gnome3 which groups windows by applications and gives preview of windows with Alt-` it isn't enough because it's hard to distinguish terminal windows from previews. You can only tell which terminal does what when the full view is shown in most cases. So is there an application/windowing system/gnome shortcut that shows you only other windows of the same application when you are switching?

  • What is the difference between Constant Vertex Attributes and Uniforms?

    - by Samaursa
    According to the OpenGL ES 2.0 Programming Guide: A constant vertex attribute is the same for all vertices of a primitive, and therefore only one value needs to be specified for all the vertices of a primitive. For uniforms the book states: ...any parameter to a shader that is constant across either all vertices or fragments (but that is not known at compile time) should be passed in as a uniform. I've always used uniforms for data that is constant for a primitive but now it appears that attributes can also be used in the same way. Is there more to constant vertex attribute than simply 'they are the same as uniforms'?

  • Ubuntu 12.04 update + VirtualBox VM 4.1.14 r77440 - No input

    - by Gubatron
    I can only enter my password with the keyboard and this is what I see after I login If I try to switch to a terminal with CtrlAlt+F1 I get this I don't have a clue how to fix this, or if it's even possible to fix this without access to a terminal. The recovery console does not work either. It opens, but keyboard input doesn't seem to be working for it either. Anybody had this happened? Update (next day) Keyboard input lets me do Alt+F2 and invoke a terminal, but I can't change focus to the terminal window that opens. Any tip on how to switch focus (Alt+Tab wont work) to the terminal window. Maybe looking at this you might have a clue what's going on, maybe there's no window manager loading?

  • Applications Menu disappeared [closed]

    - by Sophie Sperner
    Possible Duplicate: Applications Menu disappeared I'm using Ubuntu 12.04, classic desktop without effects. Once the indicator-applet-complete (right part of the top panel) had disappeared. I found how to fix it: Alt-Win-RightMouseClick on the panel, then "Add to the Panel", where choose "Indicator Applet Complete" to add. Now, the left part of the top panel (Applications Menu) has disappeared! If I do Alt-Win-RightMouseClick on the panel, I can add only individual Menu sections like Internet, Office, Settings etc. But how to get back the full Menu as it ought to be?

  • large product image structured data and visibility

    - by Mark Resølved
    On an eCommerce site we two images for a product. One medium sized shown on top of the page and one large photo shown on click in an overlay. We use http://schema.org/Product microdata on the page. We'd like the large, initially hidden, photo to be the main image for the product, as it's the better looking one. So it's also referenced in the XML sitemap as <image:image>. So we also put the itemprop"image" attribute on the, hidden large image. But i'm wondering is it a bad idea to use a microdata attribute on a hidden style="display:none;" element? is there a better way to embed the main image in terms of SEO, without showing it initially?

  • Problems installing 13.10 inside VMWare Player 4

    - by Thomas S.
    In the past I had no problems installing Ubuntu 12.04 inside VMWare Player 4.0.4 on my Windows 7 Pro machine. Now I installed Ubuntu 13.10 and have a couple of problems: the default screensize (even during the installation) is gigantic I've told Ubuntu to automatically login - after reboot the gigantic screen occurs without showing anything, without doing anything on mouse clicks, Ctrl+Alt+Backspace does not work switching to console using Ctrl+Alt+F1...F6 works, but is incredible slow invoking 'sudo reboot now' does not succeed, it prints Killing all remining processes... [fail] Restoring resolver state... [ OK ] Will now switch to single-user mode root@ubuntu1310:~# invoking now 'shutdown now' will soon show the same error. What I need to do to get Ubuntu 13.10 up and running in VMWare Player?

  • Unity: Nautilus folder opens in background

    - by JJD
    I am used to open a folder from the keyboard with a shortcut. The alternatives are: Use Unity Dash with the shortcut SUPER + F to open the Dash File Lens Open Kupfer with the configured shortcut (CTRL + ALT + SPACE, in my case) Then I type the name of the folder and press ENTER if it is selected. However, the window that opens up is not active but in the background. I have to press ALT + TAB to bring it into foreground. I use Ubuntu Precise (12.04.). Question: How can I configure Ubuntu, Unity, Nautilus so newly opened windows become foreground immediately? Edit: This behavior only happens when another application is already open such as GEdit. It does not happen when the only other selectable entity is the Desktop.

  • Ubuntu 11.10 Gnome Shell new window focus problem

    - by grafthez
    I'm using gnome shell with new ubuntu for few days now and have experienced really annoying behaviour with new windows. Sometimes when I use another window and press e.g. Alt Ctrl T to open new terminal window, I don't get this window being brought to front. Instead I get notification at the bottom that "New terminal window is ready to use". The same is with Pidgin being integrated with gnome shell (via extension). Every time I get new message, window pops up but doesn't show. I need to either Alt Tab it or click the notification. Is there any way to have new windows being always brought to front, and remove those annoying "Window is ready" notifications?

  • 12.10 Unity doesn't appear when using Nvidia drivers

    - by Torben Gundtofte-Bruun
    I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted. When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing. Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting... How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand. How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...

  • Can't set 1280x1024 with Nvidia Geforce 8400 GS

    - by torbengb
    I've just installed 10.04 LTS using the Windows installer. The system hangs during boot; the splash screen is frozen and it accepts neither Ctrl+Alt+F2 nor Ctrl+Alt+Del, only a hard reset. (I'm a linux noob.) When I edit the default Grub boot option to omit quiet splash, it gets to the point saying * setting sensors limit [OK] _ and there it stays. I can only get to the desktop using the Grub recovery boot option, of course with a lower resolution (800x600) but everything else seems to work fine. As I said, this is a new install. The only thing I've done is to use the Update Manager to get everything up to date, and activate the newest Nvidia driver using the "Hardware drivers" window. I had a similar problem when I installed 9.04 a year ago, and at that time posted this question with an answer that worked - this doesn't work with 10.04. Running nvidia-xconfig to create a new xorg.conf didn't fix it either (while in Recovery boot).

  • How to get differents backgrounds for each desktop working properly?

    - by MaikoID
    I've followed all the instructions for getting differents wallpapers for each desktop. I'm using Ubuntu 10.10. I've installed compiz-fusion-plugins-extra to add Wallpaper plugin on my Compiz Settings Manager (ccsm). But unfortunaly I cannot get my wallpapers working properly. I follow these instructions http://ubuntuguide.net/different-wallpapers-on-each-workspace-in-ubuntu and I just get a black background. Everything works fine after I press Win+P (I don't know what is this shortcut, refresh output I guess) or switch between ttf1 and ttf8 (ctrl+alt+f1 and ctrl+alt+f8). I tried reboot but the problem persist. What can I do to resolve this issue ?

  • Internet Explorer background-color hover problem

    - by danilo
    I have a strange Problem with table formating using IE 7. My table looks like this: In IE, when using border-collapse, the borders don't get displayed correctly. That's why I used this fix: .table-vmlist td { border-top: 1px solid black; } td.col-vm-status, tr.row-details td { border-left: 1px solid black; } td.col-vm-rdp, tr.row-details td { border-right: 1px solid black; } .table-vmlist { border-bottom: 1px solid black;} When hovering over the row, it gets highlighted with CSS: .table-vmlist tr.row-vm { background-color: #A4C3EF; } .table-vmlist tr.row-vm:hover { background-color: #91BAEF; } Now, in IE 7, when moving the mouse from the top to the bottom of the list, every row gets highlighted correctly and no problems happen. But if I move my mouse pointer from the bottom of the list to the top, every second row seems to loose the border. Can someone explain what the problem is, and how to solve it? This is my markup: <tr class="row-vm"> <td class="col-vm-status status-1"><img title="Host Down" alt="Down" src="/Technik/vm-management/img/hoststatus_1.png"></td> <td class="col-vm-name">V1-VM-1</td> <td class="col-vm-stati"> <img title="Ping" alt="Ping status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="CPU" alt="CPU status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="RAM" alt="RAM status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="C:\ Diskspace" alt="Disk space status" src="/Technik/vm-management/img/servicestatus_3.png"> </td> <td class="col-vm-owner">kus</td> <td class="col-vm-purpose">Citrix Testserver</td> <td class="col-vm-ip">-</td> <td class="col-vm-uptime">-</td> <td class="col-vm-rdp">&nbsp;</td> </tr> And the CSS: /* VM-Tabelle formatieren */ .table-vmlist { border-collapse: collapse; } .table-vmlist tr { border: 1px solid black; } .table-vmlist tr.row-header { border: none; } .table-vmlist tr.row-vm { background-color: #A4C3EF; } .table-vmlist tr.row-vm:hover { background-color: #91BAEF; } .table-vmlist th { text-align: left; } .table-vmlist td { } .table-vmlist th, table td { padding: 2px 0px; } /* Spaltenbreite der VM-Tabelle festlegen */ .table-vmlist #col-status { width: 25px; } .table-vmlist #col-stati { width: 90px; } .table-vmlist #col-owner { width: 90px; } .table-vmlist #col-ip { width: 100px; } .table-vmlist #col-uptime { width: 70px; } .table-vmlist #col-rdp { width: 25px; } .table-vmlist tr.row-details td { padding: 0px 10px; } /* Kein Rahmen um verlinkte Bilder */ a img { border-width: 0px; } /* Für Einschaltknopf Hand-Cursor anstatt normalen Pfeil anzeigen */ td.status-1 img { cursor: pointer; } img.ajax-loader { margin-left: 2px; } IE fix: .table-vmlist td { border-top: 1px solid black; } td.col-vm-status, tr.row-details td { border-left: 1px solid black; } td.col-vm-rdp, tr.row-details td { border-right: 1px solid black; } .table-vmlist { border-bottom: 1px solid black;}

  • Somes importants shorcuts of Blender does not work on Ubuntu

    - by Linko
    In Ubuntu (and Mint) some important shortcuts for Blender does not work. Alt + right click to select an edge loop (heavily used on all 3D softwares) doesn't work, a useless menu of Ubuntu pop up to ask if the application must be closed or minimize. Ctrl + Alt + 0 to define the current view as the view of the camera minimize the application. This shortcut of Ubuntu is useless, it's faster to click on the minimize icon. Ctrl + number to apply a subdivision surface level do nothing on Blender, it's one of the most used shortcut of Blender. For the moment I stay on Windows 7 just to use these 3 shortcuts.

I did all the troubleshooting I could find related to this subject. Nothing would work. I ultimately reinstalled Ubuntu 13.10. Also, I do not have an nvidia graphics card. I have an intel integrated graphics controller.
