• ASUS EPC 1015CX won't boot with display after installing additional drivers

  - by Dinesh

  I have a ASUS EPC 1015CX with Ubuntu 12.04 LTS installed using wubi alongside Windows 7. It worked perfectly after installing except that the supported screen resolution was only 800*600 instead of 1024*600. The specifications of the 1015CX device can be found here I tried installing additional drivers which was Broadcom for wireless and Cedarview-drm. By this time there was no display coming up after the boot. I could hear a voice and then the letters I typed got pronounced correctly. So, I guessed the issue has to be with the graphic terminal. I tried repair broken packages in the menu and booted and the display is now at 1024*600. But, if I restart normally the problem continues like before. As per what I found out after searching, I again opened additional drivers and installed Cedarview-graphics-driver. I tried restarting hoping it will work. But again, the result was same. There was no display but the system was working. I did more searching and followed the instructions found here. But still the result was same. I am keen to switch to linux from windows after hearing and learning great things about it. I know this community is good and always helping. I wanted to thank you all for the help in advance. Please let me know what I am doing wrong and help me to switch to linux from this same old windows.

• Configuration tools for multiple monitors for X / Linux

  - by richard

  I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: When I swapped my monitors over, the narrower (external) one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. Also the visible mouse pointer does is not aligned with the active spot, an x offset of one monitor width. I would like, in approximate order of importance: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.

• Emulator PCSX Reloaded - Fullscreen not working on Unity

  - by Leonardo Montenegro

  I have an older PS1 console with a couple of games I bought some years ago. On my pc, I'm using PCSX Reloaded - the best PS1 emulators for Linux I found so far. But I'm having a little issue on Ubuntu 12.04 Precise. I'm using Unity 3D and I'm trying to run some of my original PS1 games on PCSX Reloaded. Everything works nicely, except for fullscreen. I toggle fullscreen and specify maximum resolution for my monitor, but on fullscreen mode, both left and top unity bars aren't getting hidden. I tried changing between other graphic modes like Gnome Classic and Gnome Classic w/o Effects. On both, PCSX shows bars in fullscreen mode, so it isn't an Unity-specific issue, but an emulator problem. It's a bit annoying play games this way, so basically I'm running games on window mode for now. I'm using default OpenGL graphic plugin on this emulator. I tried changing to X11 graphic plugin and fullscreen worked, but graphics on X11 plugin aren't as good as OpenGL one. Anyone know a way to get fullscreen working on PCSX using OpenGL plugin? Or maybe another graphic plugin w/ OpenGL support.

• Demystifying "chunked level of detail"

  - by Caius Eugene

  Just recently trying to make sense of implementing a chunked level of detail system in Unity. I'm going to be generating four mesh planes, each with a height map but I guess that isn't too important at the moment. I have a lot of questions after reading up about this technique, I hope this isn't too much to ask all in one go, but I would be extremely grateful for someone to help me make sense of this technique. 1 : I can't understand at which point down the Chunked LOD pipeline that the mesh gets split into chunks. Is this during the initial mesh generation, or is there a separate algorithm which does this. 2 : I understand that a Quadtree data structure is used to store the Chunked LOD data, I think i'm missing the point a bit, but Is the quadtree storing vertex and triangles data for each subdivision level? 3a : How is the camera distance usually calculated. When reading up about quadtree's, Axis-aligned bounding box's are mentioned a lot. In this case would each chunk have a collision bounding box to detect the camera or player is nearby? or is there a better way of doing this? (raycast maybe?) 3b : Do the chunks calculate the camera distance themselves? 4 : Does each chunk have the same "resolution". for example at top level the mesh will be 32x32, will each subdivided node also be 32x32. Example below:

• Technique to have screen independent grid based puzzle with sprite animation

  - by Yan Cheng CHEOK

  Hello all, let's say I have a fixed size grid puzzle game (8 x 10). I will be using sprites animation, when the "pieces" in the puzzle is moving from one grid to another grid. I was wondering, what is the technique to have this game being implemented as screen resolution independent. Here is what I plan to do. 1) The data structure coordinate will be represented using double, with 1.0 as max value. // Puzzle grid of 8 x 10 Environment { double width = 0.8; double height = 1.0; } // Location of Sprite at coordinate (1, 1) Sprite { double posX = 0.1; double posY = 0.1; double width = 0.1; double height = 0.1; } // scale = PYSICAL_SCREEN_SIZE drawBitmap ( sprite_image, sprite_image_rect, new Rect(sprite.posX * Scale, sprite.posY * Scale, (sprite.posX + sprite.width) * Scale, (sprite.posY + sprite.Height) * Scale), paint ); 2) A large size sprite image will be used (128x128). As sprite image shall look fine if we scale from large size down to small size, but not vice versa. Besides the above mentioned technique, is there any other consideration I had missed out?

• Kinect will recognise your finger movement

  - by Boonei

  Sources inside Microsoft suggest they MS guys are tying to improve motion controller. This could be a huge boost to gaming. There are quite a few things that we can do with our fingers when playing games like driving, shooting,sports etc. If fingers are captured then  XBox will give more realistic version of our avatar. Eurogamer has also suggested the same according to their sources. It would be only(mostly) a software update and would not require a new camera, because the USB controller interface currently in place in Kinect can take in data up-to 35MBps. The current utilization is only around roughly 1/2 of it. So there is currently a facility to send more data. Little more tech data, Kinect does transmit 320×240-pixel in 30 fps, if the device could capture and transfer at 640×480 pixels, then better resolution can detect more movements compared to current level of detection. Lets wait and watch ! This article titled,Kinect will recognise your finger movement, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

• Coarse Collision Detection in highly dynamic environment

  - by Millianz

  I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

• Second monitor not detected

  - by configurator

  Note: I've seen this question quite a lot, but in all the cases I could find with answers, the answer was either "I don't know" or "use nvidia-settings (which is irrelevant to me)." I'm using Intel Sandybridge Desktop graphics, with a P8H61-M LE motherboard. How do I get Ubuntu to detect my second monitor? Clicking "Detect Displays" here doesn't do anything.

• How to Kill and Alternate X session via cli

  - by L. D. James

  Can someone tell me how to remove dormant X sessions. This question is similar to Logging out other users from the command line, but more specific to controlling X displays which I find hard to kill. I used the command "who -u" to get the session of the other screens: $ who -u Which gave me: user1 :0 2014-08-18 12:08 ? 2891 (:0) user1 pts/26 2014-08-18 16:11 17:18 3984 (:0) user2 :1 2014-08-18 18:21 ? 25745 (:1) user1 pts/27 2014-08-18 23:10 00:27 3984 (:0) user1 pts/32 2014-08-18 23:10 10:42 3984 (:0) user1 pts/46 2014-08-18 23:14 00:04 3984 (:0) user1 pts/48 2014-08-19 04:10 . 3984 (:0) The kill -9 25745 doesn't appear to do anything. I have a workshop where a number of users will use the computer under their own login. After the workshop is over there are a number of logins that are left open. I would prefer to kill the open sessions rather than try to log into each users' screen. Again, this question isn't just about logging users' out. I'm hoping to get clarity also for killing/removing stuck processes that are hard to kill. New Info While still pondering how to kill the process I wrote the following script, which did it: #!/bin/bash results=1 while [[ $results > 0 ]] do sudo kill -9 25745 results=$? echo -ne "Response:$results..." sleep 20 done After a graceful waiting period, if there isn't a better answer I'll mark this as answered with this resolution. This may resolve the problem with other stuck processes I have had in the past.

• Blur gets displaced compared to original image

  - by user1294203

  I have implemented a SSAO and I'm using a blur step to smooth it out. The problem is that the blurred texture is slightly displaced compared to the original. I'm blurring using a 4x4 kernel since that was my noise kernel in SSAO. The following is the blurring shader: float result = 0.0; for(int i = 0; i < 4; i++){ for(int j = 0; j < 4; j++){ vec2 offset = vec2(TEXEL_SIZE.x * i, TEXEL_SIZE.y * j); result += texture(aoSampler, TexCoord + offset).r; } } out_AO = vec4(vec3(0.0), result * 0.0625); Where TEXEL_SIZE is one over my window resolution. I was thinking that this is was an error based on how OpenGL counts the Texel center, so I tried displacing the texture coordinate I was using by 0.5 * TEXEL_SIZE, but there was still a slight displacement. The texture input to my blur shader, has wrap parameters: glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); When I tell the blur shader to just output the the value of the pixel, the result is not displaced, so it must have something to do with how neighboring pixels are sampled. Any thoughts?

• Upgrade won't allow second display to go to 1920x1080

  - by Rick

  I just upgraded to 10.10 last night and I'm having issues now with dual display from my laptop dock. This was working in the previous release with a manual xrandr command: xrandr --output LVDS1 --off --output DP1 --mode 1920x1080 && xrandr --output VGA1 --mode 1920x1080 --left-of DP1 When I run this now, the DP1 output doesn't have a mode for 1920x1080. The two displays are a matched pair of dell 22" that are both 1920x1080. When I attempt to manually add the mode xrandr --addmode DP1 1920x1080 and rerun my command, I lose both displays altogether. I have to then blindly reset to just one of them in order to get display back. If I avoid the 1920 and just attempt to setup DP1 at the 1280x1024 max it thinks it has, then the second display will come up, but obviously looks horrible since it's non-native resolution. I've grabbed the updated xorg intel driver from the stable X ppa and am running: 2:2.13.901-2ubuntu2~xup~maverick xrandr output Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS1 connected (normal left inverted right x axis y axis) 1280x800 60.2 + 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 connected (normal left inverted right x axis y axis) 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1

• HDMI video output not working for external monitor

  - by user291852

  I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

• I need advice on laptop purchase for university [closed]

  - by Systemic33

  I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)

• Single Responsibility Principle - How Can I Avoid Code Fragmentation?

  - by Dean Chalk

  I'm working on a team where the team leader is a virulent advocate of SOLID development principles. However, he lacks a lot of experience in getting complex software out of the door. We have a situation where he has applied SRP to what was already quite a complex code base, which has now become very highly fragmented and difficult to understand and debug. We now have a problem not only with code fragmentation, but also encapsulation, as methods within a class that may have been private or protected have been judged to represent a 'reason to change' and have been extracted to public or internal classes and interfaces which is not in keeping with the encapsulation goals of the application. We have some class constructors which take over 20 interface parameters, so our IoC registration and resolution is becoming a monster in its own right. I want to know if there is any 'refactor away from SRP' approach we could use to help fix some of these issues. I have read that it doesn't violate SOLID if I create a number of empty courser-grained classes that 'wrap' a number of closely related classes to provide a single-point of access to the sum of their functionality (i.e. mimicking a less overly SRP'd class implementation). Apart from that, I cannot think of a solution which will allow us to pragmatically continue with our development efforts, while keeping everyone happy. Any suggestions ?

• Laptop battery life drastically decreased compared to Windows 7

  - by Aron Rotteveel

  I am running Ubuntu 10.10 on my Dell Studio XPS 1640 and have about one hour of battery life in it, compared to about 2.5 hours running on Windows 7. This is with wireless and bluetooth on, but still, the difference seems incredible. What could be causing such a difference and is there a way to close the gap without losing core functionality? EDIT: here's some output from powertop. This is with bluetooth turned off and Wifi turned on. The output seems pretty normal to me, but as indicated, this is about 1 hour of battery life on a full battery... Wakeups-from-idle per second : 476.2 interval: 10.0s Power usage (ACPI estimate): 2.5W (1.2 hours) Top causes for wakeups: 30.0% (167.2)D chrome 21.0% (117.3) [extra timer interrupt] 13.9% ( 77.4) [kernel scheduler] Load balancing tick 3.4% ( 18.9)D xchat 7.1% ( 39.8) [iwlagn] <interrupt> 5.9% ( 32.9) AptanaStudio3 3.9% ( 21.6)D java 2.7% ( 14.9) [TLB shootdowns] <kernel IPI> 2.5% ( 14.1) docky 1.8% ( 10.0) nautilus 1.6% ( 9.0) thunderbird-bin 1.0% ( 5.5) [ahci] <interrupt> 0.9% ( 5.0) syndaemon 0.8% ( 4.3) [kernel core] hrtimer_start (tick_sched_timer) EDIT: after changing /proc/sys/vm/laptop_mode to 5 (it was set to 0), wakeups seem to have decreased, although usage still seems far too high: Wakeups-from-idle per second : 263.8 interval: 10.0s Power usage (ACPI estimate): 2.6W (0.9 hours) EDIT: I seem to have discovered the main cause: I was using the open source ATI Drivers. I recently installed the official ATI drivers and laptop battery life seems to have doubled since. EDIT: last edit. The previous 'solution' of installing the official ATI drivers turns out to be a non-solution. Although it does increase battery life, my laptop resolution is maxed out at 1200x800 after a reboot. (Please note that this problem does not need answering in this question as it is a seperate case)

  Dual-booting Windows 7 and Ubuntu 12.04 LTS. I went to reboot from Win to Ubu, and found a few interesting things. My POST screen is covered in blocks of epileptic colors until I hit GRUB, which continues when I try to boot into Ubuntu. These color blocks don't appear when I use my on-board VGA, so I'll just attribute to that. Grub dimensions are swapped (card vs onboard, probably), but, when interfacing with onboard VGA, the Grub Timeout Counter works and when using my card, it does not (see "[!!!]" below for more information) Booting into Ubuntu directly causes the error: SP5100 TCO timer: mmio address 0xfec000f0 already in use Booting into recovery mode, meanwhile, and then "resuming normal boot" gets me to the desktop without native 1440x900 resolution and graphic drivers can't tell the monitor it's looking at (I assume this is because it's not a full graphic boot, and as it says, some drivers won't run?) [!!!] When I reboot after going into recovery mode, the countdown timer works ONCE, puts me back into default ubuntu boot, and then does not work again until after another recovery-mode boot. Windows 7 can boot perfectly with no issues whatsoever from epilepsy color blocks or driver detection. This makes me wonder /why/ the POST screen can't handle my video card anymore. Amidst all the diagnostics, I opened my case and re-seated the videocard securely, ensuring it wasn't a loose connection-- But this did nothing to help me. Hardware I am running an NVidia GeForce GTX 8800 video card in a PCI slot. I have 4.8GiB memory, an AMD Athlon II Quad-core 640 Processor, on an MSI K9N6GM Series Mobo. Onboard video is an NVidia GeForce MCP61(V/S/P) card. Note: I did not have any of these problems yesterday, and I have been using Ubuntu intensively for a week, though it's been working flawlessly for months. I've recently been using it to mod my Android phone, perhaps I messed something up in the file system?

• Are Intel compilers really better than Microsoft ones?

  - by Rocket Surgeon

  Years ago I was surprised when discovered that Intel sells Studio compatible compilers. I tried it in particular for C/C++ as well as fantastic diagnostic tools. But the code was simply not that computationally intensive to notice the difference. The only impression was: did Intel really did it for me just now, Wow, amazing tools with nanoseconds resolution, unbeleivable. But the trial ended and team never seriously considered a purchase. From your experience, if license cost does not matter, which vendor is a winner ? It is not broad or vague question or attemt to spark a holy war. This sort of question about 2 very visible tools. Nobody likes when tools have any mysteries or surprises. And choices between best and best are always the pain. I also understand the "grass greener" argument. I want to hear all "what ifs" stories. What if Intel just locally optimizes it for the chip stepping of the month, and not every hardware target will actually work as well as Microsoft compiled ? What if AMD hardware is the target and everything will slow down for no reason ? Or on other hand, what if Intel's hardware has so many unnoticable opportunities, that Microsoft compiler writers are too slow to adopt and never implement in the compiler ? What if both are the same exactly, actually a single codebase just wrapped into 2 different boxes and licensed to both vendors by some 3rd party shop? And so on. But someone knows some answers.

• Make the sound louder in Lubuntu

  - by Andrew

  I have a Toshiba r835 running Lubuntu 11.10. Turning the volume slider up all the way doesn't give very loud sound. I've tried typing alsamixer in a terminal and turning up all the levels there to maximum, but the speakers are still fairly quiet. Is there a simple way to increase maximum volume in software? I understand that there are physical limits to the sound the laptop's speakers can produce, but I suspect my maximum volume is limited by software. EDIT: This is exactly the type of solution I'm looking for. However, it doesn't work for me. What I did: sudo pico /etc/asound.conf This file does not exist, so I create a new one, containing: pcm.!default { type plug slave.pcm "softvol" } pcm.softvol { type softvol slave { pcm "dmix" } control { name "Pre-Amp" card 0 } min_dB -5.0 max_dB 20.0 resolution 6 } I reboot the machine, and type alsamixer. I use my left/right arrow keys to inspect the various volume options. I expect to see a new option, called Pre-Amp, but I don't see one. This fix seems to work for other people. Why doesn't this fix work for me?
