• Graphics corrupt after upgrade from 11.10 to 12.04

  - by RiaanZA

  I'm stuck at the moment with an ubuntu that boots into an unusable white screen after upgrading from 11.10 to 12.04. I've tried booting into safe X mode but it just throws me back to the safe menu every time. Restore previous graphics driver, use default graphics configuration and set up new graphics configuration all don't work either. I've tried various methods of resetting the graphics from the command line, but none are working due to unmet dependencies. These cannot be fixed by doing the normal "apt-get -f install" because its saying there is a dpkg error in var/lib/dpkg/status (blank line relating to skype-wrapper). I haven't been able to find any other way to fix the dependencies yet. Can someone please give me some advice on what to do, I really don't want to go the re install route.

• Recovering problems

  - by Sova

  Just simple question(s): Is it possible to recover one whole folder? It was with photos..and if no, so when recovering, will it recover also files from the folder? (I use Photorec, but if you know better one..). I tried to get back my pics and what has returned wasn't from folder. ? And..is it normal, that it has recovered me the same things for about 5 times, with different size? Thanks in advance.

• High temperature on my laptop with Radeon Mobility HD4670

  - by Lorthirk

  As almost everyone here, I guess, in these days I downloaded Quantal Quetzal to give it a try. However I noticed that my laptop runs fairly hot with cooling fans almost always on, even sitting in the desktop doing nothing. I downloaded XSensor to read temperature sensors, and I saw that while CPU stays on about 65°C, so quiet normal I guess, the GPU sits at 75°C. In comparison my actual Windows 7 installation, which dual boots witb Quantal, stays at 59°C CPU and 65°C. So I went reading and learned that AMD dropped support for my video card from fglrx package, and that fglrx-legacy won't support 1.13 Xorg, so I'm basically stuck with OSS drivers. So I was guessing if there's anything I can try, and if it's possible that the OSS drivers could be the cause of the high temperature?

• Cannot upgrade or install 12.04 - Black screen

  - by Paul

  An update from 11.10 to 12.04 failed because of a boot into black screen (Nvidia graphics card) after selecting normal boot in Grub (recovery console was available though). I then wiped the whole partition (deleting all proprietary drivers) and tried a fresh install, but could not run the installation cd because it was booting straight into a black screen again. Now I reinstalled 11.10 (and installed proprietary Nvidia driver version 173), and would like to ask 2 questions: 1 - Is there a proven method to fix this problem from the recovery console, so that I can safely try upgrading again (without much knowledge of Ubuntu)? 2 - Is there a website which I could check for updated Nvidia drivers packaged into the upgrade, so that I can safely upgrade without running into a black screen some time later on?

• Portal View/Projection Matrix near plane

  - by melak47

  For RenderToTexture/Camera based portal rendering, the basics seems simple enough. However, with a free camera, most of the time it is going to be looking at such portals at an angle: Now a regular near clipping plane will not always work here, it will either intersect with the wall the portal is sitting on, or possibly with objects in front of the wall. The desired near clipping plane would be aligned like the portal, producing a view volume more like this: or this in 3D: So here is my question: How does one construct or "truncate" a view/projection matrix to achieve such an off-camera-normal (near) clipping plane?

• Ubuntu 12.10 Laptop temperature

  - by romi

  I'm using a laptop having dedicated graphics card with Ubuntu and Windows 7 dual boot. The windows 7 idle temperature for cpu is 51C average and gpu is 46-48.5C, and when in load Cpu temp varies between 55-61C, and GPU 49-51 MAX. But in ubuntu idle temp CPU: 54c Gpu(ati radeon,proprietary driver installed): 50C and on load cpu: 58-69C gpu:53C max. Is it normal? If not is there any solution? Note that i'm using jupiter,latest graphics driver, grub tweaks etc.

• Ubuntu freezes when gdm starts

  - by Enrique

  I have Ubuntu 10.10 (upgraded from 10.04) I was browsing in Firefox yesterday, then the PC suddenly did a reset Once it restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I can't move mouse pointer nor do anything with keyboard at this point (just after userlist shows in gdm). PS: Both, mouse and keyboard work fine, because this Ubuntu is dual-booting with a Windows XP install which loads/works fine. Here is my .xsession-errors file, but I don't have a clue what may be wrong. Thanks http://pastebin.com/GVtneEAF

• Computer won't wake from hibernate

  - by Icoo

  So I have a pretty dumb problem...I accidentaly pressed Hibernate while trying to Restart...since then my computer wont boot into Ubuntu anymore (through normal mode or single user mode - rescue mode that is)...all I get is: mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys/ on root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or dirctory Target filesystem doesn't have requested /sbin/init. No init found. Try passing init= boot arg. BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Obviously I tried to fire up the Live CD and run fsck (or e2fsck) from there (or just try to do a Check of /dev/sdb1 my partition via gparted - which is basically the same thing). But it doesn't allow me...both gparted and fsck say that the device is busy (I can't even mount it in the LiveCD to rescue data)...umount /dev/sdb1 says its not mounted...any ideas?

• Need to run `nvidia-xconfig` before booting

  - by RobinJ

  I formatted my whole hard drive, and installed Elementary OS (Ubuntu 10.10) on it in an attempt to get rid of all the problems. It failed. Every since I installed the nvidia-current drivers I first need to boot into recovery mode, and run sudo nvidia-xconfig before booting the system in the normal way. If I don't do this, it will just stop at a black screen after the boot screen, responding to nothing but CTRL+ALT+DELETE and the power button. When I boot the system after running the nvidia-xconfig command I can just start working as usual. Update I suspect it's got something to do with Plymouth. I shall have to try it again before I can confirm it, but removing the quiet and splash parameters from the kernel line in /boot/grub/grub.cfg seems to help. But still, I like my Plymouth screen. A black screen with text rolling over it (or without the text) doesn't attract me much.

• Oh Unity Launcher scrambled with color dots after log on or restart

  - by Cominatyalive

  The left hand side Unity launch bar is color scrambled after reboot, or log on. When touching it with the mouse arrow, it comes back to normal. I installed gnome shell color before this started happening. I will uninstall gnome shell color & see if this problem goes away. Any one ever see this happen. I run a Nvidia 550ti ge-force graphic card. I have the latest 295.33 driver from Nvidia installed and it does show activated in my restricted driver window. Oh yeah, before you inform me, I can tell you that yes, I do see the instructions to report bugs to the correct source. But I really don't know if this is a bug or not. Could be something else.

• Embedding Pygame to C++ [closed]

  - by Pendertuga

  If embedding Pygame to C++ to have a game be an executable, is there any extra process I would have to use in order to use Pygame functions when embedding into C++? As opposed to just writing embedding code in C++ for normal Python code? To clear cut the question I want to know if it's the same process without having to call different functions. EDIT: My question is if I have to call different functions in C++ when embedding Python code that uses Pygame modules. I am NOT using pygame2exe nor py2exe. I never even mentioned those. My question is solely about code embedding.

• How to handle jumping up a slope in a runner game?

  - by you786

  In an 2D endless runner, what should happen when the player is running "too fast" up a slope and jumps? For example, in a "normal" case: .O. . __..O_____ . / . / O/ _/ If he is moving to the right slowly enough, he will jump upwards and land on the flat part of the surface. However, if he is moving too fast, the jump will have no effect as his forward motion will bring him back in contact with the slope before he can get high enough to pass over it. When the speed is sufficiently high, there will effectively be no jump. _________ / .O/ O/ _/ Are there any known ways to solve this issue? I know it's physically correct*, but are there techniques that other games use to overcome this in a reasonable manner? As a last resort I'll have to just remove all slopes that are too slanted. *If you constrain the player to never jumping backwards.

• Custom .NET apps and clustering

  - by Ahmed ilyas

  So for a clustered environment - how would this work with your apps? what about your own custom .NET apps? Would there be a special way to develop them? I know that you can say create a simple Hello world app, and cluster that but they wouldnt be something you could see interms of the UI or anything, so they would effectively need to be developed as a Windows Service perhaps or even as a standard Console app which runs and not wait for user input but you wouldnt see any output from it (unless you redirect output to somewhere else) What im getting at here is... for those who have experience or developed a cluster application in .NET, how did you do it and what are the things to be aware of? For example we have the cloud service - fundamentally its built on clustering - if there is an outage, another node takes place and service is resumed as normal but we dont really see much of that downtime.

• screen flickering

  - by lilicus

  When using some applications (LibreOffice, Chrome) it happens that screen flicker (just for a second, or even less than a second) or screen turns into black and then back to normal again... it all happens very fast (usually when clicking with the mouse)... for example, I was searching something in google chrome and list of possible results appeared - when I double click on the search text area (not list of possible results) screen flicker... or when changing border lines in LibreOffice Calc... I managed to create screen shot while using LibreOffice Calc. I am using Nvidia 313 drivers-updates on Ubuntu 13.04. What could be the problem?

• VMWare Player pauses often

  - by pascal

  I'm using a 64bit Windows 8 inside vmplayer, with 2 virtual processor cores, virtual hard disk resides on a fast local disc and is not preallocated; host CPU is Intel i7 3770, should be capable of hardware virtualisation but I don't know if VMWare uses it; NAT networking; Sound card connected, USB connected, accelerated 3D graphics (NVidia 313.30 on host) My problem is, that the VM often pauses for a few seconds, and then speeds up for a few seconds to reach real time again. Time in the VM actually moves faster after the pause, for example all animations using timers speed up. When running, the vmware-vmx process shows ~150% CPU usage in top, but 0% when pausing (and D state i.e. waiting for IO). iotop shows normal disk writes from vmware-vmx threads, but during pauses, the flush kernel thread uses 99%. Are there some options to try so that VMWare doesn't wait for IO? I've tried a few things available from the GUI but the issue never went away…

• Black screen in kernel 3.8 (not 3.5, 3.11, 3.13)

  - by TheDeeno

  I need to use kernel 3.8 to address some docker compatibility issues. However, after installing this kernel when I attempt to boot my machine I get a black screen. The system appears to boot to the login screen (I hear the drum sounds), but the screen remains black. If I boot into recovery mode the video works, but is buggy/slow. In recover mode it looks like it's using the vesa driver. It'd be great if I can force this in normal mode. My machine has an ivy bridge intel processor with integrated graphics What should I do next to troubleshoot this?

• Mouse stopped responding after installing Ubuntu Server

  - by Danijar

  It was 2 operating systems on my machine, Windows 7 and Ubuntu Desktop 12.04, both 64bit version. All works well, firstly I installed Win, then the Desktop version of Ubuntu, lasts's GRUB rewrites windows's boot and of course added it as a variant to load. Yesterday I wish to play with Ubuntu Server 12.04, and install it as a third operating system. During the installation Server's GRUB seems to rewrite that which installed earlier (background color became black, was purple). Firstly, newly installed GRUB generates me overmuch load options for Ubuntu Desktop, by two for each kernel version (normal and recovery modes). OK, it's bearable, but most thing, that the mouse on this machine is totally stops responding, regardless which operating system I choose to load. Hope somebody help me. Thanks in advance!

• Can GJK be used with the same "direction finding method" every time?

  - by the_Seppi

  In my deliberations on GJK (after watching http://mollyrocket.com/849) I came up with the idea that it ins not neccessary to use different methods for getting the new direction in the doSimplex function. E.g. if the point A is closest to the origin, the video author uses the negative position vector AO as the direction in which the next point is searched. If an edge (with A as an endpoint) is closest, he creates a normal vector to this edge, lying in the plane the edge and AO form. If a face is the feature closest to the origin, he uses even another method (which I can't recite from memory right now) However, while thinking about the implementation of GJK in my current came, I noticed that the negative direction vector of the newest simplex point would always make a good direction vector. Of course, the next vertex found by the support function could form a simplex that less likely encases the origin, but I assume it would still work. Since I'm currently experiencing problems with my (yet unfinished) implementation, I wanted to ask whether this method of forming the direction vector is usable or not.

• Error after installing Lubuntu 14.04 through liveUSB

  - by Veritas

  A friend asked me to install ubuntu on his toshiba NB 200 netbook to replace windows xp. I formatted the flash drive, ran an nb5sum check on the iso and after running netbootin , I checked the drive for errors. No problems so far. During the installation, while everything seemed normal, the installation regularly paused until I pressed a button or moved the mouse. After restarting, it doesn't boot and it starts a shell showing : "General error mounting filesystems A maintenance shell will now be started CONTROL-D will terminate this shell and reboot the system " Any ideas? Any help is appreciated!

• Deactivate one graphicdevice in a SLI system

  - by NobbZ

  As it is now, I have a Gaminglaptop with 2 GeForce 9800M GT with SLI activated, Ubuntu 12.04. When I use any graphicdriver that is aware of acceleration features the system crashes after a short period of time. After I removed and purged jockey my system runs stable but slowly, but I can use it for now (I have to choose recovery at startup and the resume boot, botting up normal results in a colorflickering screen). But since the system is runs slowly, I would like to try to work with only one graphicdevice. First test device A, if that doesn't work test with device B. A testing tool for Windows already told me, that one of the cards doesn't work properly, but it doesn't say which one (same crashes in Windows when programs or desktop uses acceleration). Therefore I wanted to ask, if there is a way to reinstall any nVidia (or third party) driver, deactivate one of the two devices and test the stability?

• Battery life decreased after upgrade to 11.04

  - by bruno077

  After upgrading from Ubuntu 10.10, my battery life has decreased dramatically. There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours. I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet? I have a Core 2 Duo ULV, Thinkpad Edge 13

• WHy CAps lock is too slow to turn off in Ubuntu?

  - by chtsrl

  *TH*is is a strange problem. *NO*tice how the beginning of my sentences include two capitals? Well, over the years I have developed a terrible habit... and it may be too late to fix. Instead of holding shift like a normal person to capitalize my works, I hit Caps Lock, then hit the letter, then hit Caps Lock again. PRetty weird huh? I Took an official government typing test recently and scored 99 words a minute, so it hasn't been a huge hindrance until now that I use Ubuntu. IN Ubuntu, often when I do my crazy method of typing, the Caps LOck won't turn off fast enough. IT's not my keyboard. I didn't have this problem in WIndows. IT's extremely annoying. Is there a cure for this? Took the question from Ubuntu forums because it's just explaining the same problem I am having here.

• How to draw unlimited FPS on Mac OS X with OpenGL?

  - by V1ru8

  I d'like to draw as many frames as possible with OpenGL on Mac OS X to measure the performance on different scenes. What I've tried so far: Using a CVDisplayLink that has NSOpenGLCPSwapInterval set to 0, so it does not sync with the Display. But with that it's still stuck at max 60FPS Using normal -drawRect: with a timer that fires 1/1000sec and calls -setNeedsDisplay: Still not more than 60FPS Same as 2. but I call -display in the timer callback. With that I get the FPS above 60, but it still stops at 100-110 FPS. Although the frame rate should easily be at 10times more. Andy idea how I can really draw as many frames as possible?

• What is the difference between being an IT in investment bank and a professional IT company?

  - by deepsky

  Suppose there are two positions: IT in investment bank: developer for the infrastructure or the platform a famous IT company: embedded developer, linux As far as I understand, since in the investment bank not everyone will have the chance to work for the core trading system, most people just do the same job as they do in a normal IT company. And some of the tasks can even be outsourced. But in a professional IT company, you will have more chance to practice your coding skill and enhance your professional knowledge. So there are many choices when you want to change your job while the IT in invest bank not. Is this correct?
