• No windows preview option(Similar tp Windows 7) in compiz?

  - by harsh

  Guys I saw a video on the net regarding compiz to enable windows preview option when i hover a mouse over it. I installed compiz through Ubuntu Software centre and then I searched and found that there is no option called "Windows Preview" in it ! There is a unity option but it doesn't have a windows preview option. Also I would like the freedom to move unity anywhere from top-bottom-left-right. Will this damage my system? Please reply at the earliest :-|

• Collision rectangle response

  - by dotty

  I'm having difficulties getting a moveable rectangle to collide with more than one rectangle. I'm using SFML and it has a handy function called Intersect() which takes 2 rectangles and returns the intersections. I have a vector full of rectangles which I want my moveable rectangle to collide with. I'm looping through this using the following code (p is the moveble rectangle). IsCollidingWith returns a bool but also uses SFML's Interesect to work out the intersections. while(unsigned i = 0; i!= testRects.size(); i++){ if(p.IsCollidingWith(testRects[i]){ p.Collide(testRects[i]); } } and the actual Collide() code void gameObj::collide( gameObj collidingObject ){ printf("%f %f\n", this->colliderResult.width, this->colliderResult.height); if (this->colliderResult.width < this->colliderResult.height) { // collided on X if (this->getCollider().left < collidingObject.getCollider().left ) { this->move( -this->colliderResult.width , 0); }else { this->move( this->colliderResult.width, 0 ); } } if(this->colliderResult.width > this->colliderResult.height){ if (this->getCollider().top < collidingObject.getCollider().top ) { this->move( 0, -this->colliderResult.height); }else { this->move( 0, this->colliderResult.height ); } } } and the IsCollidingWith() code is bool gameObj::isCollidingWith( gameObj testObject ){ if (this->getCollider().intersects( testObject.getCollider(), this->colliderResult )) { return true; }else { return false; } } This works fine when there's only 1 Rect in the scene. However, when there's move than one Rect it causes issue when working out 2 collisions at once. Any idea how to deal with this correctly? I have uploaded a video to youtube to show my problem. The console on the far-right shows the width and height of the intersections. You can see on the console that it's trying to calculate 2 collisions at once, I think this is where the problem is being caused. The youtube video is at http://www.youtube.com/watch?v=fA2gflOMcAk also , this image also seems to illustrate the problem nicely. Can someone please help, I've been stuck on this all weekend!

• Cannot boot from K/Ubuntu install disk on my UEFI system

  - by user93241

  I just got a new system and have been trying to get it set up w/ Win7 & Kubuntu dual-boot, but I've got a major problem. The BIOS of my motherboard (an Asus Crosshair 990FX) is strictly UEFI -- there is no legacy support mode available. I've been reading up on how to get Kubuntu installed in UEFI mode but no matter what I try I cannot seem to even boot into my install CD/USB key properly. I can get as far as the selection screen ("Try Kubuntu", "Install Kubuntu"...) but this screen starts off not appearing correctly. If I try moving the cursor around it sometimes seems to correct itself and show me my choices. But once I select "Try Kubuntu" it starts loading, the screen goes black and then proceeds to flicker -- about once every 5-10 seconds or so. This continues indefinitely. I've tried this with both Kubuntu & Ubuntu installation media, even the AMD64+Mac Ubuntu variety that is supposed to be a lot more flexible w.r.t. UEFI. The only hint I've had that the system might have booted correctly is a little drum sound that plays when booting from the Ubuntu install disk. Well, that and the fact that when I hit my system's power button it seems to shut down correctly, even ejecting the CD at the end. This might be a video driver issue; my system has two nVidia 550's, one of which is attached to my primary monitor. (The secondary isn't hooked up yet.) I'll keep looking over similar questions but any advice would be greatly appreciated. UPDATE: I've tried booting into my 12.04 install CD twice now, each time using two different options supplied by my BIOS. One seemed to offer the ability to boot into my CD under UEFI mode -- this didn't even produce the initial boot menu. The other method offers the ability to boot into my CD NOT under UEFI mode. This DOES produce the boot menu, but after this point it seems I still cannot get to a proper video mode to see what's going on.

• Managing large downloadable content on mobile devices

  - by larromba

  This is a general question of how to best manage large downloadable content on mobile devices. Lets consider a situation whereby a mobile app needs to download a number of very large content items, like HD videos, that are over 500MB but under 2GB. Now, lets assume this content delivery system should be scalable. Would it be a fair assumption that: A reputable cloud service would be needed - if so, what is a reliable and cost effective cloud service for mobile devices based on anyone's experience? Large content downloads should only be attempted over a wifi connection, so the end user doesn't incur large costs, e.g. when travelling. Downloads should carry on in the background if possible, as the user won't want to wait in an app for long periods. If the downloads don't finish, or the OS quits the app, all downloads should carry on when the app is next activated? Are there any other pitfalls anyone may have experienced when managing large content on mobile devices? Thanks.

• Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

  - by Villi Magg

  I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.

• PowerXpress error with Driver Catalyst. How can I fix it?

  - by J03Bukowski

  I have install Ubuntu 11.10 64bit on my Hp Dv6-3150el. My Notebook has two graphics cards: lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] I tried to install the proprietary graphics drivers ''fglrx'' available in "Additional Drivers", which does not give me 3D graphics acceleration (and I can't install those post-release). Then I can try to download and install from the website (I tried the version that Catalyst 11.8 11.12). The installation goes perfectly (I followed this guide and others), except that when I configure Xorg.conf file: sudo aticonfig --initial PowerXpress error: Cannot stat '/usr/lib64/fglrx': No such file or directory Failed to initialize libglx for discrete GPU

• Trouble with FGLRX in quantal x86_64

  - by Dii Leoo

  it's the third time i have to reinstall quantal because the fglrx is making me sick. I have an ATI Mobility Radeon HD 4250 (the code ir RS880).When i install Ati Driver, i don't have any problems, but when i reboot, the resolution is minimal and the launcher isn't visible, i can only use the things that are in desktop and use the terminal using CTRL+ALT+T. i've tried to make specific distribution page, downloading the legacy driver from AMD, and another thing: when i had 12.04 jockey told me that i could install some drivers, i had trouble, but that doesn't matter. now, the option to install drivers doesn't tell me about any drivers, i mean, its blank. At the moment i'm using the free drivers (Gallium 0.4 on AMD RS880M. is there any alternative ? or i'll have to live with the free drivers ? Thanks a lot ! I KNOW I HAVE TO INSTALL LEGACY DRIVERS, I'VE INSTALLED THEM, THEY DON'T WORK.
