• Why does apt-get install Skype easily while aptitude complains about MAJOR dependency errors?

  - by Prateek

  I was trying to install Skype on Ubuntu 13.04, from the Canonical repositories. With apt-get it worked easily, while aptitude had a huge problem with dependencies and proposed a complicated solution. Why is this so? Why doesn't aptitude offer whatever apt-get does as a potential solution? Here is the output of both: apt-get install skype: Reading package lists... Building dependency tree... Reading state information...

• Ubuntu Sluggish and Graphics Problem after Nvidia Driver Update

  - by iam

  I just recently started using Ubuntu (12.04) since a few weeks ago and noticed that the interface is very slow and sluggish: On Dash, I have to type the entire app name and wait a few seconds before it shows up in the search box, and a bit later before it displays search result Opening new files or applications takes also quite long and awkward Dragging icons or moving app windows around is not very spontaneous too: I have to take extra attention in moving the mouse otherwise Ubuntu would not do a correct movement or might ends up doing something incorrect instead e.g. opening the windows to full screen options or move the file to different folders, which is frustrating My PC is a few years old already (1.7 GB RAM) so this could be a reason too but when I checked in System Monitor it's hardly ever consuming much memory. Plus web-surfing on Firefox is actually lightning fast (much more than Windows), so I suspect there might be something wrong with the graphics driver (mine is GeForce 7050). I checked around System Settings and found an option to update the Nvidia driver. So I tried it and restarted, as instructed. Now, I got into a big problem upon restart... as the login-screen windows (where I have to type in the password) would take several attempts to display and finally did not manage to (it'd freeze for several seconds before there's any movement again). The background screen also kept reloading several times too and at some point the screen turned black with pixelated color strips running on the bottom 1/3 of the screen, and after a long while the background screen would come up again. Eventually I'd manage to be able to access the desktop but the launcher, top menu bar and app windows border would not disappear. I searched around and found many other people have this similar problem after updating Nvidia driver too, and on some threads the suggestion is to use "killall -u $USER" in command line (it's the only thing among various online suggestions I could do, as at that point I could not access Terminal without the launcher - Ctrl-Alt-T doesn't work for me). So I did that and was able to access the desktop correctly again with launchee/menu by creating a new account. But I would still have the same problem if logging into my original account. So I just finally tried upgrading to 12.10 and now can access my original account with fully-functional desktop - the launcher, menu and windows border are all back now. However, the problem with sluggishness still remains. And now I get scared of ever having to update the Nvidia driver again! I wonder if anyone knows what's the reason that updating the Nvidia driver is causing this problem and is there a way I can update it safely in the future? I'm still not sure how to solve the problem with the sluggishness too and not sure where else to look to find a solution.

• Global menu not showing in Ubuntu 12.10 with Unity

  - by William

  I am on Ubuntu 12.10 with Unity shell. I am not quite sure what happened, but today I noticed that the menubar (containing 'File, Edit, etc...') is not appearing on the panel as it used to (i.e. the global application menu), but on the application window under the title bar. The only application that still uses global menu is Chromium. Any ideas what settings may have changed? Also, when I right click on the desktop and select "Change Desktop Background", System Settings opens, instead of the "Appearance" settings. Apparently, here is a related question, with no answer: Global menu and HUD suddenly broken EDIT: I noticed this behavior on three of my computers after an update (I do not remember exactly which packages were updated). Now when I try to run apt-get upgrade, I get: The following packages have been kept back: gnome-control-center gnome-control-center-data I guess something is going on with updates. Any info would be appreciated.

• How prevent useless content load on the page in Responsive Design

  - by Ícaro Leandro

  In Responsive Design, we hide elements in the page with @media queries and display: hide in the CSS. Ok, But in my system: Browsers that have less than width: 800px, the layout must hide some content, not only hide, but avoid them load fully. I mean, in access with desktop with more than 800px of screen, the page load fully; In mobile devices, or even in desktop with less than 800px, not load some content. I want to make the page load faster in this browsers. The system are maked in PHP and have some Javascript. Thanks...

• Stop Screenlets from minimizing

  - by Capt.Nemo

  I've setup my screenlets exactly the way that I want them, but I don't have a quick access to any of them. The screenlet config offers me the following : keep above,below, sticky, locky, widget. Out of these only treat as Widget seems to be of any use here. I just looked at this in detail and thought it was what I was looking for. It might have been a workaround for the issue (instead of minimizing I would just press F9. But this means that the widget hides itself from the normal desktop, which is not what I want. What I want is that on pressing Ctrl+Alt+D or Super+D, I should see the desktop with my screenlets there. I don't want them to minimize with the rest of the windows. As a final struggle, I've thought of a solution using compiz to declare the screenlet windows as non-minimizing, but surely there must be a better way than that. (Instructions for this would be helpful as well - I'm not sure what to enter in the rule matches)

  I have installed Ubuntu 13.04 (64-bits) alongside Windows 7 on different partition on my second desktop. It's working nice. I have updated everything. However, I have problems with my fan. It's blowing non-stop and very fast(loud). I haven't these problems in Windows 7 where it works nicely. How to update drivers for my fan or something else? My desktop is: HP Pro 3410 Microtower PC. Graphic card: AMD Radeon HD 6570 Board: 2A9C 1.1 Bus Clock: 133 megahertz BIOS: American Megatrends Inc. 6.14 11/05/2010 Processor: 3,20 gigahertz Intel Core i3 550 DRIVERS I HAVE TRIED FOR MY GRAPHIC CARD: I have tried these drivers so far: xserver-xorg-video-ati, version: 1:7.1.0-0ubuntu2 fglrx Version: 2:9.010-0ubuntu3 fglrx-updates Version 2:9.012-0ubuntu1 But the fan is still blowing like a maniac. I have tried to install Linux Mint 15 previously and I have had the same problems with the fan. Any idea how to fix it?

• How to remove the graphical user interface?

  - by Praveen Kumar

  Ok my question is that, I want to run a heavy application, on a Virtual Machine (VirtualBox) with just 2 GB RAM (Windows 7 32Bit Host has 4 GB, 3.5 GB effective). Initially I thought of installing Ubuntu Server 12.04.1, which doesn't come with a GUI, so I thought it would be efficient in performance, but I have only Ubuntu 12.04 Desktop. My question is, is it possible to remove the GUI parts in Ubuntu 12.04 Desktop (Not Server), keeping only the core OS, after installation in a virtual machine? Or, is there anyway to improve the performance of the OS? If you need more information, I am ready to provide. I don't want the GUI or anything, even a small terminal window is fine for me, I can access files through FTP.

• Atheros Wireless card shows up as two different models?

  - by geermc4

  Hi I've been fighting these wireless drivers for a few days and just recently i noticed that the model the Wireless controller appears in lspci is different sometimes. This is the data i have after installing Ubuntu Server 64 bit ~# lspci -k .... 04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Subsystem: AzureWave Device 1d89 Kernel driver in use: ath9k Kernel modules: ath9k ran some updates, restarted, all was good, all though it did say that linux-headers-server linux-image-server linux-server where beeing kept back. After that i installed ubuntu-desktop (aptitude install ubuntu-desktop --without-recommends) restarted and not only is the wireless not working anymore, but the hardware is listed as a different card ~# lspci -k .... 04:00.0 Ethernet controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) has no available drivers for it, still i tried to modprobe ath9k, they show up in lsmod as loaded, but still iw list shows nothing. this is what it looked like before the ubuntu-desktop instalation Wiphy phy0 Band 1: Capabilities: 0x11ce HT20/HT40 SM Power Save disabled RX HT40 SGI TX STBC RX STBC 1-stream Max AMSDU length: 3839 bytes DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 8 usec (0x06) HT TX/RX MCS rate indexes supported: 0-7 Frequencies: * 2412 MHz [1] (14.0 dBm) * 2417 MHz [2] (15.0 dBm) * 2422 MHz [3] (15.0 dBm) * 2427 MHz [4] (15.0 dBm) * 2432 MHz [5] (15.0 dBm) * 2437 MHz [6] (15.0 dBm) * 2442 MHz [7] (15.0 dBm) * 2447 MHz [8] (15.0 dBm) * 2452 MHz [9] (15.0 dBm) * 2457 MHz [10] (15.0 dBm) * 2462 MHz [11] (15.0 dBm) * 2467 MHz [12] (15.0 dBm) (passive scanning) * 2472 MHz [13] (14.0 dBm) (passive scanning) * 2484 MHz [14] (17.0 dBm) (passive scanning) Bitrates (non-HT): * 1.0 Mbps * 2.0 Mbps (short preamble supported) * 5.5 Mbps (short preamble supported) * 11.0 Mbps (short preamble supported) * 6.0 Mbps * 9.0 Mbps * 12.0 Mbps * 18.0 Mbps * 24.0 Mbps * 36.0 Mbps * 48.0 Mbps * 54.0 Mbps max # scan SSIDs: 4 max scan IEs length: 2257 bytes Coverage class: 0 (up to 0m) Supported Ciphers: * WEP40 (00-0f-ac:1) * WEP104 (00-0f-ac:5) * TKIP (00-0f-ac:2) * CCMP (00-0f-ac:4) * CMAC (00-0f-ac:6) Available Antennas: TX 0x1 RX 0x3 Configured Antennas: TX 0x1 RX 0x3 Supported interface modes: * IBSS * managed * AP * AP/VLAN * WDS * monitor * mesh point * P2P-client * P2P-GO software interface modes (can always be added): * AP/VLAN * monitor interface combinations are not supported Supported commands: * new_interface * set_interface * new_key * new_beacon * new_station * new_mpath * set_mesh_params * set_bss * authenticate * associate * deauthenticate * disassociate * join_ibss * join_mesh * remain_on_channel * set_tx_bitrate_mask * action * frame_wait_cancel * set_wiphy_netns * set_channel * set_wds_peer * connect * disconnect Supported TX frame types: * IBSS: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * managed: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP/VLAN: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * mesh point: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-client: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-GO: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 Supported RX frame types: * IBSS: 0x00d0 * managed: 0x0040 0x00d0 * AP: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * AP/VLAN: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * mesh point: 0x00b0 0x00c0 0x00d0 * P2P-client: 0x0040 0x00d0 * P2P-GO: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 Device supports RSN-IBSS.

• Is Java easy decompilation a factor worth considering

  - by Sandra G

  We are considering the programming language for a desktop application with extended GUI use (tables, windows) and heavy database use. We considered Java for use however the fact that it can be decompiled back very easily into source code is holding us back. There are of course many obfuscators available however they are just that: obfuscators. The only obfuscation worth doing we got was stripping function and variables names into meaningless letters and numbers so that at least stealing code and renaming it back into something meaningful is too much work and we are 100% sure it is not reversible back in any automated way. However as it concerns to protecting internals (like password hashes or sensible variables content) we found obfuscators really lacking. Is there any way to make Java applications as hard to decode as .exe counterparts? And is it a factor to consider when deciding whether to develop in Java a desktop application?

• CRT as 2nd monitor goes screwy after start up?

  - by rhys

  new install of 12.04 on an old dell with a radeon ATI RV516 video card with monitor out and s-video out. During boot up all is good. Both screens operate and look fine. Then just before the desktop appears the cCRT goes purple and is covered in heavy horizontal lines, but as i said during boot up it was fine and the resolution was fine. The main monitor, an lcd, operates normally. everything else works fine, it's just the picture on the CRT that is screwed up. I used the same monitor and CRT running 11.10 which worked fine any help would be appreciated and yes i am a newbie to ubuntu here is a vid showing the completely normal screens at reboot then the purple badness when the desktop loads ?? and don't laugh at the slow machine, it's old. http://www.youtube.com/my_videos_edit?ns=1&video_id=zfuh6lBMLnc

• How to upgrade Compiz to 0.9.8 in 12.04?

  - by Naveen

  For a very long time, I'm experiencing this bug in Compiz. It makes my windows flash, when rotating the desktop cube. None of the animations work properly execpt the Wobbly windows. However the temporary fix I found on the bug page helped me to reduce the effects, but it's not 100% perfect. Now they have totally fixed the bug in Compiz 0.9.8 for Quantal. I really need to get the official fix on my Ubuntu 12.04. Don't the LTS versions get bug fixes? Sometimes my desktop cube/cylinder appears like this : None of this happened in Lucid Lynx :( Thanks for having a look.....

• Is there a keybind to minimize all windows, without a toggle?

  - by George Marian

  I know about the show desktop keybind (default Ctrl+Alt+D), which I use often enough. However, I'm looking for a way to minimize all windows without activating "show desktop". I'm on a default install (i.e Gnome, Metacity & Compiz). I've looked through all the locations to configure keybinds, that I know. I've also looked at the default keybind list in the Ubuntu wiki and in the Compiz wiki. (Not to mention, searching here.) I'm interested in knowing where it is available, if not in Gnome/Metacity/Compiz, or some other way to accomplish this with a keybind.

• Good, simple reasons for having a multiple environments

  - by smp7d

  Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't phased because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I cant really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

• Not able to install ubuntu 12.10

  - by Janet

  When I try to install Ubuntu on my computer I get this error: /var/cache/apt/archives/compiz-gnome_1% 3a0.9.8.4+brz 3412-0ubuntu0.1_i386.deb and /var/cache/apt/archives/metacity-common_1% 3a2.34.8-0ubuntu4_all.deb Ok, since I'm not a whiz at installing linux or understanding it...When these two things popped up it stated that the file was corrupted and there were too many errors to complete the install. Now, does that help? I had Ubuntu 12.04 LTS on my computer and wanted to upgrade, now I have nothing on my desktop and when I tried to install by using my usb pen, nothing happen and I also have it on dvd and tried to install from that and nothing still happen. So maybe someone can tell me why it's not installing on my desktop? I have it on my laptop with Windows.

• How can you remove Unity from Ubuntu Netbook Edition

  - by Brad

  In previous versions of Netbook Remix I was able to disable the netbook-launcher and just have a blank desktop. I liked the speed of the Netbook version but not the interface, this worked well for me. However, now with 10.10 and Unity I'm having trouble doing a similar thing. I tried removing netbook-launcher from the startup and tried uninstalling unity. The best result I got was a black desktop with a panel and a non configurable blank white background. Is Unity soo integrated into this version that I will have to just go with the default ubuntu installation?? In the past the default version has been slower then the Netbook version without the interface. Thanks.

• How do I fix gnome shell themes?

  - by Chris

  This is my fifth full format and install of Ubuntu in under a month. I finally have my Gnome 3 desktop working again, but again, the Gnome shell themes is not select-able. I have asked the question of how to fix this common issue before, but I have seen no positive resolution. Does anybody know of a simple fix? This is a common issue and I have seen hundreds of postings related to it, but other users only seem to get half-way answers also and it goes unresolved. Would it be advisable to completely purge Gnome desktop and reinstall? If so how would I do this? I cannot use any extensions if the shell is not working, so I am desperately seeking resolution for the issue. Thanks in advance.

• How can I assign custom icons to folders?

  - by Frank Souza

  How do I assign custom icons to folders, as well as the default folders Desktop, Downloads, Music, etc.? I know that one way is to assign the properties of folders, but I want to assign icons in the same way that are assigned the default folders, so the custom icons will also appear in the Nautilus bookmarks. I've also seen this question custom icon in "Places" menu <<, but that is not what I seek. UPDATE My main intention is this: I want the markers to display custom icons like the dolphin. I know it's possible, because the folder "Desktop", "Documents", "Music" has its own custom icons in bookmarks. How?

• Actor library / framework for C++

  - by Giorgio

  In the C++ project I am working for we would like to use something like Scala actors and remote actors (see e.g. this tutorial). Being able to use remote actors (actors living in different processes, possibly on different machines and communicating via TCP/IP) has higher priority for us because we have an application consisting of several processes deployed on different machines. Being able to use several actors living in the same process (possibly different threads) is also interesting, but has lower priority for the moment. On wikipedia I have found some links to actor libraries for C++ and I have started to look at Theron. Before I dive too deep into the details and build an extended example with Theron, I wanted to ask if anybody has experience with any of these libraries and which one they would recommend.

• Future-proofing myself when learning to program.

  - by Chris Bridgett

  I want to learn to program in a 'future-proof' manner, if you like. Whilst Windows dominates the desktop OS marketplace (for now), obviously there is a lot of value in learning its languages/frameworks/API's and so on - this might be subject to change as new devices emerge or Windows shoots itself in the foot (over-friendly previews of Windows 8 don't look too appealing...). Would I be right in thinking that having a solid knowledge of C/C++ for back-end logic/low level programming and the like, combined with an extremely portable language like Java for GUI's and so on, would be a good basis for software development that will prove useful on the most amount of systems? - I'm talking desktop PC's, tablets, phones.

• How do I install the Intel Graphics driver in my system?

  - by John

  Can someone help me out and explain or point me in the right direction on how to check video drivers and see if my video card running okay? I had 10.04 installed on my Thinkpad r61 with Compiz Manager and life was great, until the machine took water damage. I bought an ASUS (X54H) since and am trying out 12.04, but the desktop just doesn't look right. I always struggled with video driver installation. There are no proprietary drivers available in the hardware manager. When I run lspci | grep VGA: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) I will greatly appreciate your help. I want to use Linux more, but like I said video drivers appear to be my biggest concern. I have also tried 12.04 on my desktop PC, but again failed to configure video card, so switched back to Windows 7.
