  • How can I get the best performance for playing games?

    - by Oli
    I've been playing a couple of Wine-games today and decided to switch to metacity to see what the performance difference was like. If you've never done it before, you just run metacity --replace but don't do that if you use Unity! Anyway, surprise surprise it was like playing on a dedicated Windows gaming machine. Playing under metacity today was bliss. Much higher framerates and just a fluidity that you'd expect from a native game. I'm not sure I can go back. Switching to metacity is no hardship but I wonder if there's anything else in the WM landscape that I should try out. I'm essentially looking for suggestions for the best way to play games. Mix up WMs, dedicated X sessions, whatever... As long as it makes Wine games run faster. Small print One process per answer (eg: New X session + OpenBox) We should probably land on a benchmark so we can show percentage improvement over a stock Compiz desktop. I'm open to suggestions in the comments. If people could test it and submit their how much it improves things for them in the comments, that would give others a good idea of if it's worth the pain.

  • Is there going to be Twinview ( or alternative) implemented for nouveau ?

    - by lisak
    as I've had heavy issues with nvidia driver regarding performance of basic X window operations (window moving, resizing, scrolling). I switched to nouveau driver. But I lost the possibility of having dual screen that I had previously thanks to nvidia twinview feature... Anyway I rather have fluent X than dual screen, but having dual screen would be nice, so I'm wondering if there is already an nouveau alternative to nvidia's twinview or if it is going to be implemented.

  • Lenovo Y460 Intel Driver Secondary Display Flickering

    - by ultimatebuster
    This is a part of the massive dump of problems I'm encountering with my Lenovo Y460 and Ubuntu. Problem: ATI PowerXpress doesn't really work. Doesn't work as I have to use the open source driver with hacks. Turned off ATI card at boot Details on how I accomplished that: http://ubuntuforums.org/showthread.php?p=10955831#post10955831 Installing the ATI drivers results in a failure of the intel drivers to work with Ubuntu Class (all animations have to turned off). Anyway to fix this problem to allow switchable graphics to work? The problem above has been fixed by FGLRX (Catalyst 11.6) is it compatible with kernel 2.6.39? However, there's another issue. If I connect my secondary monitor (VGA 17'') while using the Intel driver, I would not be able to use that screen as there's flickering and tearing, making the screen blurry and usable. Here's the fglrxinfo: $ fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile GEM 20100330 DEVELOPMENT OpenGL version string: 1.4 (2.1 Mesa 7.10.2) Any fixes for that? Potential related bug report on launchpad: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/750259 However I can't confirm because the video showing that is much more dramatic than what I have, mine are tiny flickering that won't be captured by video cameras as I've tried, but enough to make it blurry for humans.

  • Update Manager error 12.04

    - by Shannon Marisa
    I'm using Ubuntu 12.04. When attempting to run my Update Manager, it doesn't allow any of the updates to be loaded. Under "details" all it says is "patch". It won't even load anything when the Partial Upgrade option comes up. I thought that this Error in Update Manager would help me, but when I followed the instruction and looked for the "PUBKEY" in Terminal, there was none, it said "BADSIG" and "failed to fetch 11.10" instead and my Update Manager still doesn't update anything. I'm still new to the finer points of Ubuntu and could really use some advice. Did I do something wrong? Or I need to do a fresh install?

  • Upload File From URL

    - by Ryan Naddy
    I have been using Windows for a while, and with it there is a feature when you want to upload a photo (for example) to a website, you click on the "Choose File" in Chrome to upload a photo, a "File Explorer" opens, and instead of selecting a file from the hard drive you can paste a URL into the "File Explorer" and press open and it will download the file from the web to your temporary files, and use it to be uploaded. Is there any way I can do that in Ubuntu 12.10? Here is the windows example:Upload from url via File Explorer

  • How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

    - by max
    I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?

  • Can the parameters of the Music Lens be edited?

    - by Ryan McClure
    I primarily listen to classical music on my laptop. Since I'm obsessed with specifics with my music, I am precise with how I label my genres (Opera, Symphony, Chorale, etc.). Is there a way to edit the Music Lens so that instead of listing "Blues, Classic, Country..." it could list custom parameters? Could the same be done for the "Decade" parameter? Maybe make it "Century", since I have music from back in the 1400's :)

  • Is there anywhere where I can get Ubuntu installed for me?

    - by user3911336
    I have tried for days to install Ubuntu on my lenovo ideapad z510 and I feel like giving up. I really feel like I will like Ubuntu, but for some reason I always have some king of problem. I really don't want to give up on Ubuntu, but I don't want to brick my laptop either. Is there anywhere I can have Ubuntu installed for me? I have tried messing with my bios, used a DVD and a USB, but no luck. Thanks in advance! Edit: I am based in Warwick, RI in the USA. I don't want to run Ubuntu in windows.

  • Dual booting windows 8/ubuntu 12.04. Grub doesn't appear and machine never boot in ubuntu

    - by black sensei
    i got a new ACER predator AG3620-UR308 which came with windows 8, so i wanted to run ubuntu 12.04.2 on it as a dual booting. To be honest, i've been doing dual booting for a while now so, i did the right thing. the box came with 2TB HDD. so i made 4 partitions with a raw partition just after the windows installation partition I always do manual installation so even if ubuntu didn't detect windows 8, it was ok for me. So i created swap area and finished the installation etc....Grub was install on the only drive there which is sda. After reboot, grub doesn't even come up.So it always boot in windows 8. I did repeat the installation process twice and yield same result. which is weird because this method always works for me so far.Even the laptop am using to write this post is a dual booting windows 7/ mint nadia installed the same way. Is there anything new in windows 8 that i didn't make provision for? Before starting the installation, all i read about was that , windows 8 should be installed first and ubuntu after. I went ahead and disable secure boot from the BIOS and enabled CSM (don't even know what it means) according to Acer custhelp site . I boot from USB and did fdisk -l bellow is the result: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

  • ifconfig can't see USB wireless

    - by Alex
    I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

  • How do I replicate the Super Key?

    - by joemangrove
    If you use xmonad, xbindkeys, and xdotool to try and remap the 'Menu' key, it does not work perfectly. The 'Menu' key will only emulate the Super key's quick press action, bringing up the application search. If you hold in the 'Menu' key it will not emulate the Super key's hold down action. That is, bring up the launcer with numbers over the applications. How do you make another key on the keyboard act exactly like the Super key?

  • How can I always show the close, minimise and maximise buttons on their windows and keep global menus?

    - by sup
    First, this is not a duplicate of How can I always show the close, minimise & maximise buttons into their own windows? - I would like to preserve global menus. Is there a way to only always show the close, minimise and maximise buttons on every application? The use case is as follows: I have a maximized application in the background, over it is a not-maximized application that has got focus. I want to close the maximized application. I move the pointer to upper left corner. The buttons do not show, since the background application does not have focus. I have to go back, click on it and then go back to the corner to close it. I do that several times a day :-( .

  • How can I set up the Trusty Desktop ISO for preseeding?

    - by user288087
    With Precise, I used to create a USB stick using the so-called "Alternate" installer DVD with my own preseed.txt, update isolinux/txt.cfg with a new menu item that would pass my preseed file on the command line, and watch as the installer happily did all the right things to create a Ubuntu install on the hard drive of the machine I booted. With Trusty, the 'alternate' image has disappeared. Is it still possible to preseed a Trusty install, and if so, how do I get the d-i/ubiquity system to use my preseed file?

  • ubuntu 12.04 server doesn't resolve local domain name

    - by jdog
    After apt-get upgrade this morning, my Ubuntu 12.04 web server does no longer resolve a domain name hosted on it. I also received the error message: "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." I found this question Network Manager not populating resolv.conf but the solutions provided there did not resolve the problem. Creating the symlink in fact caused websites to load very slowly, so I assume there is some sort of (reverse?) DNS lookup not working, when I create the symlink.

  • How can I access old KMail emails after upgrading to Ubuntu 11.10?

    - by Gary Kleppe
    I initially installed Ubuntu 11.04 and used KMail for my email. All well and good. Then I upgraded to Ubuntu 11.10. Presumably an upgrade of KMail took place as part of this. Now KMail won't even run; when I try, it tells me "Failed to fetch the resource collection" and crashes. I don't mind switching to another email client, but I'd very much like to be able to recover all of the emails I have stored in KMail. Any suggestions on how to do this? Thanks for any help anyone can provide.

  • Why is everything crashing?

    - by Kopkins
    I've been using Ubuntu for a while now and I love it, I wouldn't think of using another OS unless I can't fix this issue. The install I'm on is only around a month and a half old. I'm running 12.04 64bit on a 8,1 MBP. Up until around 2 weeks ago everything was running smoothly. Around then applications started crashing and weird things started happening. At first I thought it was just certain applications. The first thing to start giving me trouble was compiz. Occasionally compiz will stop decorating windows and lost many other functionalities. running compiz --replace fixes this, but I don't feel like doing it usually once a day. The other thing with this is that after running compiz --replace, my conky window gets lost somewhere and so I run killall conky && conky -c .conkyrc. But this isn't with just a couple applications, it seems like it is proliferating through my system. Last week fontforge started crashing while doing whatever task. So I ended up unable to finish what I was working on to completeness. Didn't find a fix. Today rhythmbox started crashing. Whenever I try to play anything, Rhythmbox becomes unresponsive and needs to be forced to close. When I try to do certain things with the disk utility, it crashes. I get the Ubuntu has experienced an internal error message much more often than I would like. Frequently applications stop appearing in the launcher. Wine almost never does anymore. After not being active for a little while, thunderbird can only fetch my mail after restarting wireless, sudo rmmod b43 && sudo modprobe b43 Occasionally some of my startup apps don't start. What is my best option here? Could they be bugs? I don't want to submit a ton of vague bug reports. Reinstall? switch OS? Thank you to anyone who responds. Kopkins

  • Disabling monitor reconfiguration when closing lid

    - by Tomas
    I often need to move my laptop from one working place to another. When I do this, there are two events Ubuntu responds to by changing the monitor set up: Removing/attaching the VGA cable Closing/opening the lid of the laptop While removing the VGA cable gives me what I need (single screen, highest native resolution on the external screen if connected; otherwise highest resolution on the laptop), the laptop close/open lid response is not as good. Every time I close or open the lid, Ubuntu reconfigures the monitor set up. When I close the lid now... the screen goes black for a few seconds and it switches to clone, with my laptop screen disabled. Reopening results in... briefly a black screen, then the external monitor being used as desktop extension. Ubuntu thinks too much. My first and foremost question: Is there any way to let Ubuntu ignore lid close events? Ideally (or when there's no way to solve above question) I'd want to change how it deals with the screen reconfiguration. Why does Ubuntu toggle the screen configuration between external, clone and single display? Can't I just configure it to always use the external monitor, when present, in single screen mode? Note that similar questions have been asked before (most notably this one), but these have been closed perhaps wrongly. Any ideas are very welcome, I don't mind playing around a bit to see if something works.

My Network Card is the Realtek RT8139 and from what Ive gathered the ethernet port driver for it is installed. Whenever I run ifconfig in the terminal it says that eth1 is up and running but no matter how I edit the connection I cannot get it to work. If anyone can help it would be greatly appreciated!

  • Can't ping external websites

    - by Frantumn
    I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.
