  • Why suspend / hibernate does not work in Ubuntu 10.10? (blank screen problem)

    - by agn0stic
    I've got a problem with Ubuntu 10.10 suspend / hibernation. When I try to do one of these actions, computer prepares but in the end a blank screen comes up with just a single underscore blinking. Computer becomes unresponsive to mouse/keyboard and only pressing power button on chasis restores it. Disks and coolers are working during the suspend / hibernation as if nothing happened. Can anyone give me some advice how to solve it? Thank you.

  • How to force Debian to boot new Kernel?

    - by ThE_-_BliZZarD
    I'm running Debian 6, Debian GNU/Linux, with Linux 2.6.32-5-amd64 under Grub2 ( 1.98+20100804-14+squeeze1) on a remote system (no possibility to view the pre-boot messages). I compiled and installed a new kernel, but I can not get it to boot. What I have done: Installed the packages via: dpkg -i linux-headers-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb linux-image-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb This updated the Grub configuration. My /boot/grub/grub.cfg now contains: menuentry 'Debian GNU/Linux, with Linux 3.5.3.20120914-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 3.5.3.20120914-amd64 ...' linux /vmlinuz-3.5.3.20120914-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-3.5.3.20120914-amd64 } menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 2.6.32-5-amd64 ...' linux /vmlinuz-2.6.32-5-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-2.6.32-5-amd64 } I used grub-set-default "Debian GNU/Linux, with Linux 2.6.32-5-amd64" to set the old kernel as default and then grub-reboot "Debian GNU/Linux, with Linux 3.5.3.20120914-amd64" to boot into the new kernel once. After update-grub I rebooted the system, but everytime it comes back up with the old kernel (2.6). I tried setting the new one as default (grub-set-default 0, update-grub, reboot) but, still the old one. The Syslogs contain NO hint whatsoever about trying to boot the new kernel - only the old one. Would there be any hints regarding problems with a kernel? Is there a way to enable debug-logging in grub? What am I doing wrong? How can I force the system to boot the new kernel?

  • How can I display additional boot and shutdown information on the Windows 7 welcome screen?

    - by Daniel Saner
    There is a small tweak, I believe it is a registry key, that allows to display additional information on the Welcome and Shutting down screens of Windows 7 (and most likely Vista, too). I have activated this tweak on one of my systems; unfortunately I forgot how I did it, and I can't seem to find the website that originally gave me that information. Usually, the Windows 7 welcome screen will just display "Welcome" when logging in. With the tweak activated, my Welcome screen gives status information such as "Loading user settings" or "Preparing desktop". When shutting down, the default screen simply says "Shutting down". With the tweak activated, it gives additional status information such as "Stopping Windows services". This appears the same way that Windows gives information when updates are installed or configured during the startup or shutdown procedure, and I find them quite helpful in getting a feel for what task takes how long during that process. The only setting I was able to find is the Boot log checkbox on the Boot tab of the msconfig application. However, this results in Windows displaying console logs of drivers it is loading, etc., instead of the animated Windows title. This is NOT the setting I am looking for. The "additional boot information" setting that I have activated on this system still displays the regular animated Windows logo, and only replaces the strings displayed on the blue Welcome and Shutdown screens. Could someone direct me to the registry key (or whatever setting) that is used to get this behaviour? Edit: Here are a few pictures of the enhanced Welcome and Shutdown screens taken with my mobile phone—they're in German though. Login screens "Waiting for User Profile Service" and "Preparing desktop": Logout screen "Stopping Windows services":

  • Can't add Fedora 14 to grub.

    - by Dananjaya
    Today I installed Fedora 14 in a different partition in the same hard drive as Ubuntu. At the Fedora 14 installation, I chose not to install Boot-loader in the MBR, and instead chose to install it in the Fedora partition itself, which is according to my HD layout /sda3. After the Fedora 14 installation I booted in to Ubuntu and ran sudo update-grub but 'grub.cfg' fails to add Fedora 14 in to the OS list. Here is the output of boot-info script.

  • How to strip out a -D for just one file in a gnu makefile?

    - by WilliamKF
    I have '-Wredundant-decls' in my CXXFLAGS but for one file, I want it removed. In my GNU makefile, how can I structure a rule to remove just that part of the CXXFLAGS. I know how to add only for that file, I would do something like this: $O/just_one_file.o: CXXFLAGS += -Wredundant-decls So, ideally I'd do something like this (which doesn't work) to remove it: $O/just_one_file.o: CXXFLAGS -= -Wredundant-decls However, maybe with some $ magic, I can construct some kind of sed or perl script to strip out the -Wredundant-decls and set CXXFLAGS to the stripped value: $O/just_one_file.o: CXXFLAGS = $(shell strip magic here for $CXXFLAGS)

  • Day 2 - Game Design Documentation

    - by dapostolov
    So yesterday I didn't cut any code for my game but I was able to do a tiny bit of research on the XNA Game Development Technology and the communities out there and do you know what? I feel I'm a bit closer to my goal. The bad news is today I didn't cut code either. However, not all is lost because I wanted to get my ideas on paper and today I just did that.  Today, I began to jot down notes about the game and how I felt the visual elements would interact with each other. Unlike my workplace, my personal level of documentation is nothing more than a task list or a mind map of my ideas; it helps me streamline my solutions quiet effectively and circumvent the long process of articulating each thought to the n-th degree. I truly dislike documentation (because I have an extremely hard time articulating my thought and solutions); however, because I tend to do a really good job with documentation I tend to get stuck writing the buggers. But as a generalist remark: 'No Developer likes documentation.' For now let's stick with my basic notes and call this post a living document. Here are my notes, fresh, from after watching the new first episode of Merlin second season! Actually, a quick recommendation to anyone who is reading this (if anyone is): I truly recommend you envelope yourself in the medium or task you're trying to tackle. Be one with moment and feel it! For instance: Are you writing a fantasy script / game? What would the music of the genre sound like? For me the Conan the Barbarian soundtrack by Basil Poledouris is frackin awesome. There are many other good CD's out there, which I listen to (some who even use medival instruments, but Conan I keep returning to. It's a creative trigger for me. Ask yourself what would the imagery look like? Time to surf google for artist renditions of fantasy! What would the game feel like? Start playing some of your favorite games that inspire you, be wary though, have some self control and don't let it absorb your time. Anyhow, onto the documentation... Screens, Scenes, and Sprites. Oh My! (groan...) The first thing that came to mind were the screens, I thought the following would suffice: Menu Screen Character Customisation Screen Loading Screen? Battle Ground The Menu Screen Ok. So, the thought here is when the game loads a huge title is displayed: Wizard Wars. The player is prompted with 3 menu items: 1 Player Game, 2 Player Game, and Exit. Since I'm targetting the PC platform, as a non-networked game to start, I picture myself running my mouse over each menu option and the visual element of the menu item changes, along with a sound to indicate that I am over a curent menu item. And as I move my mouse away, it changes back, and possibly an exit mouse sound. Maybe on the screen somewhere is a brazier alit with a magical tome open right beside it, OR, maybe the tome is the menu! I hear the menu music as mellow, not obtrusive or piercing. On a menu item select, a confirmation sound bellows to indicate the players selection. The Esc key will always return me to the previous screens or desktop. The menu screen must feel...dark, like a really important ritual is about to happen and thus the music should build up. 1 Player Game - > Customize Character(s) 2 Player Game - > Customize Character(s) Exit - > Back to Windows Notes: So the first thing I pick up here are a couple things: First and foremost, my artistic abilities suck crap, so I may have to hire an artist (now that i've said that, lets get techy) graphical objects will be positioned within a scene on each screen / window. Menu items will be represented grapically, possibly animated, and have sound / animation effects triggered by user input or a time line. I have an animated scene involving a brazier or fire on a stick IF I was to move this game to the xbox, I'd have to track which menu item is currently selected (unless I do a mouse pointer type thing.) WindowObject has a scene A Scene has many GameObjects GameObject has a position graphic or animation MenuObject is a GameObject which has a mouse in, mouse out, and click event which either does something graphically (animation), does something with sound, or moves to another screen.  Character Customisation Screen With either the 1 or 2 player option selected, both selections will come to this screen; a wizard requires a name, powers, and vestements of course! Player one will configure his character first and then player two. I considered a split screen for PC but to have two people fighting over a keyboard would probably suck. For XBox, a split screen could work; maybe when I get into the networking portion (phase 2 blog?) of this game I will remove the 2 player option for PC and provide only multiplayer and I will leave 2 player for xbox...hmm... Anyhow...I picture the creation process as follows: Name: (textbox / keyboard entry) - for xbox, this would have to be different. Robe Color: (color box, or something) Stats: Speed, Oomph, and Health. (as sliders) 1 as minimum and 10 as maximum. Ok, Back, and Cancel buttons / options. Each stat has a benefit which are listed below. The idea is the player decides if he wants his wizard to run fast, be a tank and ... hit with a purse.Regardless, the player will have a pool of 12 points to use. Ideally, A balanced wizard will have 5 in each attribute. Spells? The only spell of choice is a ball of fire which comes without question. The music and screen should still feel like a ritual. The Character Speed Basically, how fast your character moves and casts. Oomph (Best Monster Truck Voice): PURE POWAH!!! The damage output of your fireball. Health How much damage you can take. Notes: I realise the game dynamics may sound uninteresting at the moment; but I think after a couple releases, we could have some other grand ideas such as: saved profiles, gold to upgrade arsenal of spells, talents, etc...but for now...a vanilla fireball thrower mage will suffice for this experiment. OK. So... a MenuObject  may need to be loosely coupled to allow future items such as networking? may be a button? a CharacterObject has a name speed oomph health and a funky robe color. cap on the three stats (1-10) an arsenal of 1 spell (possibly could expand this) The Loading Screen As is. The Battleground Screen For now, I'm keeping the screen as max resolution for the PC. The screen isn't going to move or even be a split screen. I'm not aiming high here because I want to see what level of change is involved when new features / concepts are added to game content. I'm interested to find out if we could apply techniques such as MVC or MVVM to this type of development or is it too tightly coupled? This reminds me when when my best friend and I were brainstorming our game idea (this is going back a while...1994, 6?) and he cringed at the thought of bringing business technology into games, especially when I suggested a database to store character information and COM / DCOM as the medium, but it seems I wasn't far off (reflecting); just like his implementation of a xml "config file" for dynamic direct-x menus back before .net in 1999...anyhow...i digress... The Battle One screen, two characters lobing balls of fire at each other...It doesn't get better than that. Every so often a scroll appears...and the fireballs bounce off walls, or the wizard has rapid fire, or even scrolls of healing! The scroll options are endless. Two bars at the top, each the color of the wizard (with their name beside the bar) indicate how much health they have. Possibly the appearance of the scrolls means the battle is taking too long? I'm thinking 1 player controls: up, down, left, right and space to fire the button. Or even possibly, mouse click and shift - mouse button to fire a spell in the direction they are facing. Two player controls: a, s, d, f and space AND arrows (up, down, left, right) and Del key or Crtl. The game ends when a player has 0 health and a dialog box appears asking for a rematch / reconfigure / exit. Health goes down when a fireball (friendly or not), connects with a wizard. When a wizard connects with a scroll, a countdown clock / icon appears near the health bar and the wizard begins to glow. For the most part, a wizard can have only scroll 1 effect on him at a time. Notes: Ok, there's alot to cover here. a CharacterObject is a GameObject it travels at a set velocity it travels in a direction it has sounds (walking, running, casting, impact, dying, laughing, whistling, other?) it has animations (walking, running, casting, impact, dying, laughing, idle, other?) it has a lifespan (determined by health) it is alive or dead it has a position a ScrollObject is a GameObject it carries a transferance of points "damage" (or healing, bad scroll effect?) (determinde by caster) it carries a transferance of "other" it is stationary it has a sound on impact it has a stationary animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by game) it is alive or dead it has a position a WallObject is a GameObject it has a sound on fireball impact? it is a still image / stationary it has an impact animation / or transfers an impact animation it is dead it has a position A FireBall is a GameObject it carries a transferance of poinst "damage" (or healing, bad scroll effect?) (determinde by caster) it travels at a set velocity it travels in a direction it has a sound it has a travel animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by caster) it is alive or dead it has a position As I look at this, I can see some common attributes in each object that I can carry up to the GameObject. I think I'm going to end the documentation here, it's taken me a bit of time to type this all out, tomorrow. I'll load up my IDE and my paint studio to get some good old fashioned cowboy hacking going!   D.

  • How can I leave the remote screen locked when I ARD/VNC/etc. to my Mac?

    - by Dominic Cooney
    I'm currently using Jolly's Fast VNC and Mac OS X's built-in VNC server (System Preferences, Sharing, Screen Sharing) to access my iMac remotely. Here's my problem: When I'm using the iMac remotely, the screensaver deactivates and the screen is unlocked. If someone had physical access to my iMac they could walk up to it and start using it. Is there some way I can set things up so that when I'm using my iMac remotely the screen stays locked, like Windows XP Professional does when you're using RDP? I know I can use X remotely with the iMac locked, but I would like to use Mac applications remotely, too.

  • Why would the boot screen be displayed on the external monitor?

    - by hegearon
    Why would the boot screen be displayed on the external monitor? This is not really a problem, I'd just like to know the reason behind this. If I boot without an external monitor both the BIOS settings and the boot screen are displayed on the built-in LCD monitor. However, when I boot with a monitor attached, the boot screen and the BIOS settings are displayed on the external monitor. There isn't any setting available regarding this in the BIOS setup (as opposed to my Thinkpad T42 where there is an option regarding this).

  • Is there an application that can do a blue screen effect with a webcam?

    - by Axxmasterr
    Background: This is not the blue screen of death I am speaking of but the process called "Blue Screening" that takes and removes a particular colored background from an image so that it can be superimposed on some other video/still picture. If you have ever seen the weatherman stand in front of the map, then you have seen someone doing a blue screen technique. I would like to be able to capture video from my webcam, then send that video to a blue screen program which removes the white (or other color) from the background and then inserts a background of my own choosing. (think of the dead guy in freejack who was calling from all of the different places on earth) Then once the image is superimposed, I would like to pipe it into Skype for video conferencing. Anyone have a good way to do this?

  • Customizing the windows server 2008 RDP login screen possible?

    - by moontear
    Hi, I'm working with RDP sessions quite frequently. As we work in teams and all use the same user account on a particular computer (I know...) I was wondering if there was a way to display from which computer (hostname, computername) the person is connecting. The login screen I get when two users are already connected looks like this (german): I'd love it, if the screen would display from where the logged in user is connecting e.g. "COMPUTER\user connected from MYCOMPUTERNAME". This way I would know whom to ask to disconnect so I can hop onto the session. If I remember correctly the login screen looked different for previous Windows versions including this connection information. Any way I can easily enable this or is this just standard windows behavior and there is no way to tell from where the user is connecting (btw: Task Manager shows the computername of the connected user).

  • Is there a way to snip part of the screen with a hotkey?

    - by Head of Catering
    I'm able to launch the snipping tool, select an option and then copy based on my selection. Is there a way to launch a default snipping option so that I can create partial screen screenshots without using a third-party tool? Essentially, I'm looking for winkey+S without having to use OneNote. Both OneNote and SnagIt implement this perfectly. If OneNote is running, pressing winkey+S allows me to click and drag any portion of the screen, including pop-out menus with selections that are active. SnagIt does almost the exact same thing, invoked by the prt screen key.

  • Win 7: How can I resize a window to make it much bigger than my screen?

    - by RexE
    I have a window that I'd like to make much bigger than my physical screen (explanation of why below). I hit Alt+Space, M, and then press the Up arrow to move the title bar above the physical top of my screen. However, when I press Enter to set it, the title bar snaps back to the top of my screen. How can I prevent this from happening? Background: I want to get a hi-res image of a neighborhood map so that it can be printed to a poster. Google Earth has a "Save as JPG" feature, which will save the map in the window to a file. The bigger the window, the bigger the JPG; so, I'm trying to make the window as big as I can. Alternate suggestions welcome.

  • How to disable the Windows 8 lock screen, without disabling the password?

    - by zeel
    Windows 8 now has a slide-away lock screen like so many other OSes designed for a touch interface. However on a non-touch PC/laptop this is just an extra annoying step in logging in. There is an option to disable it, but this also turns off the password requirement. Is there a way to disable the lock screen, and have Windows wake up directly to the password entry screen? Often when pressing a key to hide it there will be a noticeable delay before password entry is accepted, and no indicator, so one can easily lose the first character or so that they attempt to type, thus failing the login attempt.

  • When to use new layouts and when to use new activities?

    - by cmdfrg
    I'm making a game in Android and I'm trying to add a set of menu screens. Each screen takes up the whole display and has various transitions available to other screens. As a rough summary, the menu screens are: Start screen Difficult select screen Game screen. Pause screen. Game over screen. And there are several different ways you can transition between screen: 1 - 2 2 - 3 3 - 4 (pause game) 4 - 1 (exit game) 4 - 3 (resume game) 3 - 5 (game ends) Obviously, I need some stored state when moving between screens, such as the difficulty level select when starting a game and what the player's score is when the game over screen is shown. Can anyone give me some advice for the easiest way to implement the above screens and transitions in Android? All the create/destroy/pause/resume methods make me nervous about writing brittle code if I'm not careful. I'm not fond of using an Activity for each screen. It seems too heavy weight, having to pass data around using intents seems like a real pain and each screen isn't a useful module by itself. As the "back" button doesn't always go back to the previous screen either, my menu layout doesn't seem to fit the activity model well. At the moment, I'm representing each screen as an XML layout file and I have one activity. I set the different buttons on each layout to call setContentView to update the screen the main activity is showing (e.g. the pause button changes the layout to the pause screen). The activity holds onto all the state needed (e.g. the current difficulty level and the game high score), which makes it easy to share data between screens. This seems roughly similar to the LunarLander sample, except I'm using multiple screens. Does what I have at the moment sound OK or am I not doing things the typical Android way? Is there a class I can use (e.g. something like ViewFlipper) that could make my life easier? By the way, my game screen is implemented as a SurfaceView that stores the game state. I need the state in this view to persist between calls to setContentView (e.g. to resume from paused). Is the right idea to create the game view when the activity starts, keep a reference to it and then use this reference with setContentView whenever I want the game screen to appear?

  • How do I reduce the screen and file size of a recorded video, plus convert to FLV?

    - by Volomike
    I have used gtk-recordMyDesktop to make a video as an OGV file using the default settings. I need to do 3 things: How can I reduce the screen resolution (height and width) so that it can fit into a smaller video size on my website? How can I pull out like every third frame so that the file size is not so large, yet not mess up the sound? Not all Windows IE users can view OGV files. How can I convert to FLV (or, as a fallback, MP4) so that I can share on my blog?

  • Bless doesn't fix white boot screen boot delay for single-boot Xubuntu 14.04 on Macbook 4,1

    - by elephant
    I still have a 30-second delay on the white boot-up screen before Xubuntu loads after trying various combinations of bless --device as recommended here: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation#Avoid_long_EFI_wait_before_GRUB I wonder if anyone has experienced this before, or can point me to some good steps for troubleshooting this issue? I have cycled my macbook dozens of times, it would be great to be able to boot quicker. I am single-booting Xubuntu 14.04 (no Mac OSX partitions or any other OS, just a GRUB partition at sda1, a main partition at sda2, and a swap at the end of the drive). Suggestions very appreciated.

  • Name of web design technique with vertically contiguous but separate screen-sized blocks?

    - by Chad Schultz
    I don't know the proper name for this, which makes it hard to Google it or describe this. On a site like http://p2theme.com/ as you scroll down you see that content is arranged into screen-sized chunks, each with its own chunk of content, each with a different background color, making them visually distinctive. I've seen this used more and more frequently on websites, but don't know what it's called. People have tried telling me "responsive design" or "flat UI" or "infinite scroll" or "parallax" -- but those are completely different things. What do you call this technique?

  • How would I be able to get a game over screen using the pause function?

    - by Joachim Velzel
    I am having problems with my snake game, when the snake collides with itself it draws a "game over" image in the background, but only while it's colliding with itself. I want it to behave like the pause function, so that as soon as the snake collides with itself it draws an image on the screen and stops the game play. And then how would you be able to restart or to quit the game? I just have this for the detection at the moment: if (snakeHeadRectangle.Intersects(snakeBodyRectangleArray[bodyNumber])) { spriteBatch.Draw(textureGameOver, gameOverPosition, Color.White); } Thanks
