• Can't install Ubuntu on a HP DV6 Laptop

  - by EApubs

  I just bought a HP DV6 6011tx (link) Laptop. I formated the disk through Windows and prepared for installing Ubuntu. But when I inserted the live CD, it showed the Ubuntu start screen and then everything went black. There was no cursor, everything just stayed black like the screen was switched off (but the system is running). When I tried to install from the USB, it said Live media is not found. Sometimes it also gave me a black screen like the CD. Does anyone have any idea how to fix this? Thanks!

• Ubuntu partitions on Dell XPS13

  - by Francois

  I bought a Dell XPS13 with ubuntu 12.04 pre-installed. I want to reformat and repartition the machine but as I'm far from being a linux guru, I'm afraid to erase something important that could have been preinstalled by Dell. On the disk, there are 3 partitions: /dev/sda1 - Ext4 Linux bootable 248GB - witch is the system+user partition I guess, /dev/sda2 - Extended (?) of 8GB - What is this partion about? /dev/sda5 - Linux Swap of 8GB - whitch is for RAM and need to be reconduct (why only 1xRAM and not 2?) Do I have to care about /dev/sda2 ? According to you can I reformat to create a partition for /home whitout losing anything important (except user data of course) ? Thank you for your help

• Install matlab with wine

  - by user33831

  I have been moving from windows to ubuntu recently. I have both windows 7 and matlab for windows license keys. My question is, is it possible to use wine to install matlab(for windows)? will the performance of matlab being affected? Except wine, dual-boot, and purchase a new matlab for linux license key, what other options do I have? Thanks for help Update: I just searched for virtual box, will it be a good alternative? Update: After trying with virtualbox, I believe it will not be a good option, because it only run with the ram allocated for it. Seems like I can only purchase a new license, if I dont want to dual-boot, which is quite not convenient. Thanks for all replies.

• Is Clojure, Scala and other restrained by the JVM vs CLR

  - by jia93

  The Java implementors seem slow to adopt language improvements, for example compare C# with full closures, expression trees, LINQ etc.. to Java, and even the push back of some stuff to Java 8 will still leave it behind the current implementation of C#. However since I dont intend to use either Java or C# that particular language war isnt of interest too much, im more concerned with the JVM vs CLR. Is this lagging-behind also applicable to the JVM? Will Scala, Clojure etc.. will they be able to continue to innovate or score optimal performance in the face of slowly progressing underlying VM such as JVM? Is Clojure/Scala restrained at present by JVM limitations?

• Throttle and overheating on Dell XPS Studio 1645

  - by Ross

  I realise there is an older thread on the very subject but that seems to be pretty dead. I just got a Dell Studio XPS 1645 laptop and the fan noise and overheating is pretty ridiculous. This is actually a well known problem with the laptop that is apparently solved with the combination of a BIOS update and the purchase of their 130w charger. I plan on buying this charger as soon as possible, however I've noticed that since installing Ubuntu the fan noise has became more permanent and the overheating is quite a bit worse too. I've had to turn it off twice to let it cool down for an hour or so because it starts seriously affecting the performance. It makes watching things, listening to music or leaving the laptop on while I sleep a real pain. If anyone has some new information on this issue or could help out in anyway at all I'd be very grateful. Thanks.

• Public Cloud, co-location and managed services ... what is the cloud?

  - by llaszews

  Recently I have had conversation with a number of people that are selling and implementing 'cloud' solutions. I put cloud in quotes as implementations like co-location (aka co-lo) and managed services (sometimes referred to as 'your mess for less') have become popular options for companies moving to the cloud. These are obviously not pure public cloud offerings and probably more of hybrid cloud implementations as the infrastructure (PasS and IaaS)is dedicated to a specific customer. This eliminates the security, multi-tenancy, performance and other concerns that companies have regarding public cloud. Are co-location and managed services cloud to you? Are they something your company is considering when you think about cloud ?

• How to manage two video cards on a laptop (ATI and Intel)?

  - by Marc-François Cochaux-Laberge

  I have a laptop with two video cards. One ATI and on integrated Intel. On Windows, I can choose which video card I want to use. For example, I use the Intel card for normal use and for gaming, I switch to my ATI card for better performance, but a shorter battery life. In Ubuntu 10.10, only the Intel driver is installed, the ATI driver for my card doesn't work at all and there's heat coming out of my computer all the time, like when I'm playing video games on Windows. I think both cards are active, but only the Intel one is usefull. How can I solve this by making sure Ubuntu is aware of the two video cards and by disabling my ATI. Or may be I am all wrong about this?

• How to disable the Mount notification in Gnome 3.4?

  - by Thompson

  How to disable those annoying notifications when you plug a new disk in, or connect to a network and so on.... I know that if I add a device to a mount script they will be mounted on boot thus not showing me the notification, which I did for my hard drives, but it doesn't help with all those flash disks I have... I can't add them all that would be silly. I looked at: How can I disable gnome-shell's notification area? ... but they didn't help, since the code was different I also looked at configuration editor, but I think it can only disable auto-mount when inserted, it doesn't disable notification...

• What are the advantages and disadventages of git or bzr + rsync vs rdiff-backup?

  - by Azendale

  I used to use rsync to do backups, but then I switched to rdiff-backup to incremental backups. Recently, I discovered git and bzr while working on a coding project. So, I was thinking, I could have my backup disk be a repository in either git or bzr. Then I could rsync to the repository, and commit the changes. Would there be any performance concerns with this? Any other issues that I'm not thinking of? The benefit I see in using rsync is that you can restart an interrupted transfer, while rdiff-backup reverts to the last version, and then starts again. Any reason not to do it this way? Anything I'm not thinking of?

• PHP accessible shared content between two websites on the same VPS on different domains/IPs

  - by Lee Fentress

  I have two ecommerce websites, selling music digital downloads, on the same VPS, currently using cPanel/WHM (but thinking of switching to Virtualmin). They have separate domains and IPs of course. They both share from the same set of music files, so I have duplicate copies in each website directory, which takes up a lot of disk space. How might I go about sharing the same set of music files across both sites, allowing PHP access, so that it does not break my shopping cart's functionality of serving customers the downloads after they have paid for them? I thought of maybe using symlinks or something, but I don't know if it's possible, or if it would have to somehow circumvent built-in security features of the server. I'm new to VPS management.

• How to Restrict Android App Permissions

  - by Chris Hoffman

  Android forces you to agree to every permission an app wants, assuming you want to use the app. After rooting your device, you can manage permissions on a per-app basis. Restricting permissions allows you to protect your contacts and other private data from apps that demand access you’d rather not allow. Many apps will continue working properly after you revoke the permissions. HTG Explains: What Is RSS and How Can I Benefit From Using It?

• Asus 1215n GPU driver/s don't give me a "full" OS experience

  - by AFD

  I'm use to not having specific drivers from a manufacture on my laptop when running a Linux OS and that has always been fine - there's been adequate FOSS drivers for my needs and it hasn't ruined any of my OS experience. When I bought an Asus 1215n one of the upsides to the hardware seemed to be the switchable GPU that could give lots of performance or lots more battery life and would switch on-the-fly... with Windows of course. Seems that the Nvidia driver are crap and people advise not installing them. I have some sort of workaround for vga_switcharoo (?) and the on-the-fly nature of the GPUs has turned in to a manual one :( The worst bit though (aside from shorter battery life) is the web experience with HTML5. If I visit Mozilla's Web O'Wonder site I'm told I don't have WebGL working due to driver issues. This really blows - is it possible that proprietary drivers can now ruin my web experience too?!

• Which one scales better asp or php?

  - by Marin

  Let's say the website is doing fine(forums,pictures,ajax). And it needs scaling up/scaling out. I feel more comfortable with php but I have worked with asp.net as well. Would you say asp.net is much more powerful, more robust and thus easier to scale out? What would be the pros and cons of converting the website to asp.net in regards to scalability and performance versus keeping the website written in PHP? Examples of personal experience in making such a conversion would be a plus. Thank you.

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• ANTLRWorks 2: Early Access Preview 10

  - by Geertjan

  I took a quick look at how the ANTLRWorks 2 project is getting on... and discovered that today, March 23, the new early access preview 10 has been released: http://www.antlr.org/wiki/display/ANTLR4/1.+Overview Downloaded it immediately and was impressed when browsing through the Java.g file that I also found on the Antlr site: (Click to enlarge the image above.) On the page above, the following enhancements are listed: Add tooltips for rule references Finally fixed the navigator update bug Major improvements to code completion Fix legacy mode Many performance and stability updates I've blogged before about how the developers on the above project consider their code completion to be "scary fast". Some discussions have taken place about how code developed by the ANTLRWorks team could be contributed to the NetBeans project, since NetBeans IDE and ANTLRWorks 2 are both based on the NetBeans Platform.

• How to convert an XFS file system to HFS+

  - by user219350

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but ! " Basically, I work on OSX-Mavericks 10.9.3, which sees very Windows 8.1 and works wonders with NTFS, but does not see Ubuntu! Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.
