• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• SDL: How would I add tile layers with my area class as a singleton?

  - by Tony

  I´m trying to wrap my head around how to get this done, if at all possible. So basically I have a Area class, Map class and Tile class. My Area class is a singleton, and this is causing some confusion. I´m trying to draw like this: Background / Tiles / Entities / Overlay Tiles / UI. void C_Application::OnRender() { // Fill the screen black SDL_FillRect( Surf_Screen, &Surf_Screen->clip_rect, SDL_MapRGB( Surf_Screen->format, 0x00, 0x00, 0x00 ) ); // Draw background // Draw tiles C_Area::AreaControl.OnRender(Surf_Screen, -C_Camera::CameraControl.GetX(), -C_Camera::CameraControl.GetY()); // Draw entities for(unsigned int i = 0;i < C_Entity::EntityList.size();i++) { if( !C_Entity::EntityList[i] ) { continue; } C_Entity::EntityList[i]->OnRender( Surf_Screen ); } // Draw overlay tiles // Draw UI // Update the Surf_Screen surface SDL_Flip( Surf_Screen); } Would be nice if someone could give a little input. Thanks.

• How do I repeatedly move an image by 1 pixel?

  - by Will

  I have a method that is moving a UIImageView called shootImg across the screen: -(IBAction)shoot{ if (appDelegate.shootInt > 0) { if (direction == 1) { shootImg.center = CGPointMake(shootImg.center.x+1, shootImg.center.y); appDelegate.shootInt = appDelegate.shootInt - 1; shootLabel.text = [NSString stringWithFormat:@"%d", appDelegate.shootInt]; } This does seem to work. But it only moves shootImage 1 pixel. What I want to do is make it repeatedly move 1 pixel. I tried a while loop but that didn't seem to work. I'm not using cocos2d or anything like that and if you need to see more code just ask. Thanks :)

• UEFI hardware and dual booting with windows

  - by user39803

  I've been struggling for 3 days trying to dual boot Ubuntu 11.10 and Windows 7. I want to use an SSD for my Ubuntu installation and an hdd for Windows. I realized that I have to install windows first and then ubuntu, and so I did that. When I first install windows it boots fine from my hdd, but when I add ubuntu on my ssd and restart, I get a black screen with a blinking cursor. I've read many forums where this is asked but haven't found a single solution that works. I've tried boot repair. It told me to make a fat ESP partition and I did that as well but it still doesn't work. I'm a noob and any suggestions would be really appreciated.

• When trying running Ubuntu 12.10 off a usb drive, I encounter an error while prevent me from doing anything else

  - by Nil

  The details are that I used Universal USB Installer version 1.9.1.8 from pendrivelinux.com to install ubuntu 12.10 onto a 4gb pendrive as per instruction on Ubuntu's website. However, after I boot with drive I am met with the following message: "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Pressing Ctrl Alt F1 doesn't allow me access and the options on the dialog box either send me through a loop returning me to the previous dialog or just leave me dead in the water. Pressing Ctrl Alt Del does however restart the computer if I am dead in the water, so ubuntu isn't COMPLETELY unresponsive... I feel I should mention that I'm trying to run this distribution on my netbook. I can't install it directly to the harddrive since I need my current Windows distribution for certain programs that don't quite agree with WINE yet.

• Can I use WUBI as an offline installer for 12.10?

  - by ning

  Can I use WUBI as an offline installer? I already had the .iso file of ubuntu 12.10 - i386, and inside the iso is wubi.exe. For example: I will do a partition of, E:30gb then i will target E: in wubi so that it will be Ubuntu then use the .iso file to install it on E: My Computer: Acer Aspire 5750-6683 i5-2450m processor Is it fine to do a dual boot? Can I run Windows 7 Home Premium OS, with the custom theme and boot screen, can that effect dual booting? I just don't want to damage any of files or either any of OS And if I can't boot any of the operating systems what should I do? Can I avoid doing a clean install if that ever happens?

• Resolution problems

  - by tampe125

  i'm having some troubles with screen resolution. First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed. As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help. My natural resolution is 1366x768, but I'm stuck with 1024x768. This is my hardware: lspci | grep VGA 00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) How can I fix that? Is there a ready-to-use driver or I have to compile that from source? At least, is there a solution, at all? :(

• How do I configure the mouse to raise and lower windows

  - by user288496

  I've just installed 14.04 and cannot find the congfuration screen to control how mouse clicks are acted on by the window manager, and then optionally passed to the application. I want to set the sane traditional unix behaviour of: - 'focus follows mouse': done. - 'never auto-raise': done. - 'raise when click on border or title': Can't find the option. A middle button click on the tile does lower a window - but traditionally it would also raise the botton window. I can set 'raise on any click' - but that is absolutely hopeless when you are trying to copy text from a lower window.

• I cannot log in after theme change

  - by sssuizaaa

  After changing the gtk-theme in the gnome tweak took I was taken out of the session to the login screen and now I cannot log in. I can only log in using the guest account. So in the grub menu I selected the recovery mode and in the resulting menu I selected root-drop to root shell prompt. Once there I did a couple of things I've found in several pages and in the forums. 1.gsettings reset org.gnome.desktop.interface gtk-theme This is what I got: (process:642):WARNING: Command line 'dbus-launch –autolunch=4438d024dd45ef7fb2d3f4ab0000000f –binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n and nothing changes 2.gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme Radiance with this I was trying to change the gtk theme to the Radiance one. No strange message this time but it did not work either. I still cannot log in. Any ideas please?? sssuizaaa

• Ubuntu 12.04 x64 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive?

• How to load kernel from live cd on UEFI install of Ubuntu 12.10?

  - by Geezanansa

  Running a GYGABYTE FM1 motherboard which is using a AMD 3870k APU with a new WS Caviar 1TB HDD. Following the advice in the Motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub screen for UEFI install. The dvd.iso being used is Ubuntu 12.10 desktop amd64. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session(booted in bios mode)but decided to leave it unformatted with the intention of using installer to set up partitions. Booting live dvd gives grub list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance.

• After upgrading to 12.04 lts server, the mouse is intermittently working

  - by Jason

  After this upgrade, I've had a problem with the mouse intermittently working and programs crashing (like zentyal crashing and the error reporting application crashing) I also had an error on the screen that said: "Could not grab your mouse. A malisious client may be eavesdropping on your session or you may have just clicked a menu or some application just decided to get focus. Try again." What's going on with this system? Did I really get malware that quickly? This system has been boxed up since 2011. I only did the upgrade today... In regards to the mouse I can move it around, but when I click on something, it doesn't work.

• kernel panic - diagnosis?

  - by user94188

  I'm having a kernel panic problem - my machine will run for hours, maybe all day and then have a panic attack. I have no idea how to interpret the output, but here's a picture of what's left on the screen when it happens: https://dl.dropbox.com/u/13279067/photo.JPG (I can't post images yet) I've looked through the logs but didn't find anything obvious - I'm still learning though so I've probably missed something. It's a little harder since it's always happened when I've been out or at night so I can't pinpoint the exact time it crashed. Anyone have advice? thanks

• 14.04_x64 / Nvidia GT 240 , HUGE font notificaton at greeter and in naulitus after log-in

  - by mrlamud

  I've been using 12.04 for a long time - excellent version indeed, I decided to try 14.04 today. Installing without any problems. My VGA is Nvidia GT240 (legacy one), Nouveau display driver is fine, font display is normal. Then, I decided to install Nvidia legacy binary driver 304.117 updates (proprietary) instead of default Nouveau display driver. Problems come after rebooting At Greeter a notification "Wired connection 1 -Connected" pop up but with a HUGE font. After log-in HUGE FONT symptom still remains at some parts - for example, Calendar, Desktop shortcut and Files explorer. within few seconds, 10 to 15 may be, there is a screen blink but HUGE font still remains. I have to log out then log in again to have normal font in all parts of system. Changing driver, even an update one form ppa:xorg-edgersnot doesn't solve the problem. Any advices or solutions will be appreciated.

• System doesn't boot due to a "[drm: drm_crtc_helper_set_config] * error * "

  I have a problem with the new Ubuntu 12.10.

• Scripted Motion Paths (?) (XNA)

  - by Peteyslatts

  Ok, so the title isn't the greatest because this is a lot more general. Say I want to have the player be able to hit A and have their ship model roll to the right, and shift to the right of the screen, while the camera stays centered. Would I do that through programming (ie. set waypoints for the model and keep the camera focus still) or do it through animation ( so the ship model actually rolls and moves right, and just play those frames)(I actually don't know how to do this kind of 3D animation yet, haven't looked into it. Adding it to my To Do List) This is a really vague question I know, I'll try and answer any questions. Thanks, Peter

• 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!

• Easy Method to Change Color on UI Elements

  - by A13X

  This isn't a language-specific thing as far as I'm concerned. I was wondering what may be a quick way to change the COLOR of a certain on-screen element such as a button and its associated text. I would assume there is a trick to making a graphics engine so maybe individuals pixels or groups of sprites can have their colors easily shifted. A lot of game interface buttons and such have this so you know when an event like a click has occurred. Any pseudo code would be helpful and I am working in Android (not XML fluff), but again, this probably is not a very specific question, just an inquiry on how to go about this.

• Dell monitor not detected (Ubuntu 11.10)

  - by Charles

  I have an issue with my monitor. I just installed Ubuntu 11.10, but the monitor that is plugged in doesn't appear anywhere. And by doesn't appear, I mean that in the "Displays" menu, it doesn't even appear as "Unknown", I just have my screen that appears and nothing else. It is connected through VGA, and the monitor is recognized with no problem on Windows 7. It is a Dell monitor. I'm not a pro with Ubuntu, so any help to diagnose the issue would be really helpful (and help me learn how to fix this kind of monitor issue in the future) Thanks !

• How to disable VGA

  - by Bitmap

  If i run lspci | grep VGA I get below output which tells me below VGA cards are present on my computer. 01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2) 08:02.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02) The ES1000 is an onboard card which came with my machine. Do anyone know how to disable this VGA on my machine. The reason for this request is because if I run xrandr I get the output as shown below: xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 50.0* 800x600 51.0 52.0 53.0 680x384 54.0 55.0 640x480 56.0 512x384 57.0 400x300 58.0 320x240 59.0 Which means I am not able to configure nVidia to accept smaller resolution. Thank you.

• How to change color of the frame of a maximizing window

  - by SteliosSk

  Though I have read and tried some advises regarding the change of colors in a theme, I found no answer regarding my question, which is: When I drag a window to the left (or right or up) side of the screen an orange frame shows up, indicating the area that the window will occupy. This frame is in orange. Can you please inform me how can I change this color to blueish, to match my theme? At this point, I would like to inform you that Zorin OS has this blueish frame instead of orange, but I do not know where this color comes from.

• Newly updated ubuntu not loading in moniter.

  - by user211652

  I just recently upgraded from Ubuntu 12.04 to Ubuntu 12.10. I installed the update and tried to boot from the newly installed version. As I booted in it would pop up the loading screen and then I would lose signal and it would say that there was no signal on my monitor. How do I fix this because I really want to use the new version but if it's not going to work I'll just forget about it. I can however boot into the old install and I works fine.
