Hello. I am a newcomer to Daniweb and need some advice. I've been using Ubuntu regularily on several PCs and note books installing without problems until now. I have just purchased an Acer Aspire ES 11 (ES1-132-CONU) that is using an Intel Celeron Quad Core 3450 processor launced Q3'16 possibly from the Kaby Lake 7th gen batch. Installation USB /CDs for versions 14.04 and 16.04 won't boot. Version 16.1 will boot and I can go thru the 'try without installing' and without any problem. Then after adjusting the Windows 10 partition, etc. and installing Ubuntu 16.1, can only boot to …

Hello everyone. I realize that this may be an elementary question, but all of my searches for answers have not given me a satisfactory result. In my ubuntu server machine, I typed in [after examining my stty settings] `werase='^I'` as I was configuring the terminal to my likings. All was fine after I made that change and the command worked beautifully. After I logged out and logged back in, I could not use that shortcut anymore and I had to manually reprogram it to use it again. Could anyone suggest how I can fix this problem and make the setting …

Hi all, I am running a mySQL database on a webserver hosting multiple Wordpress installations. It seems that database is getting swamped with memory and going into a continual loop of shutting down and restarting. A reboot fixes the issue temporarily, but I have no idea what I can do to fix this. When the issue presented itself a month ago I realise I had not created a swap drive. I have now done so, but web traffick has increased since then and I suspect this may be the cause. Interestingly, when I SSH into my Ubuntu Server, I get …

Hi there, I'm a long time PHP programmer, 6 month newb python developer, but entirely new to git and gitlab. I've spent 2 solid work days trying to solve this issue, I've chatted with others in chat rooms, all to no avail. I'm not certain where I should post this question, but I figure it's a software issue so I'll initially place it under Software Development. I installed XenServer (A hypervisor for virtual machines), then Ubuntu Server 14.04 LTS on that, and then the most up-to-date Omnibus Gitlab package. I've assigned the machine 4 CPU's, 4GB ram, and 50GB inital …

On certain websites you can order laptops, and sometimes even they allow you to change certain parts of it. Let's take the example of HDD, the website offered quite an amount of types of HDD's. The largest HDD they can deliver to the laptop is 2TB, could I instead ask them to let the slot open, and then buy let's say 860EB and put it in. * Will Linux adapt these entire 860EB? Will it be able to write to this disk as it could to normal 2TB disk? Is there no limitation to amount of data understood? Entire 860EB …

I had 2 Linux's on my laptop. But I really needed to start something that required DirectX in it, also, it had to be on Windows. I tried to use VMware and VirtualBox but to no avail, so it had to be real machine, not virtual one. I installed Windows 7 next to both Ubuntu's. After installation, when I tried to open boot menu of 3 machines, only 1 appeared, Windows 7. I was scared I might've clicked on wrong button or something and I lost all "sensitive" and (for me) important data that I had encrypted in `home` folder. …

Server information: Ubuntu 14.04 Apache2 I installed PHP5 on my webserver and tried to run a script that contained a call to the function curl_init(). The server responded with an error indicating that the function curl_init() was undefined. I installed PHP-CURL and restarted my webserver and encountered the same error. I created an info.php file containing a call to the function phpinfo() and checked to see that the CURL extension was installed and not only did the page say that the module was installed but it also said that CURL was enabled. I'm still recieving an error saying that curl_init() …

I have been creating small personal projects and trying to monetize or just learn from the creation process. I love programming and I am doing it as a hobby, looking forward to become a strong developer as soon as possible. Starting out I used Joomla, Wordpress, Drupal as CMSs but soon I needed more custom solutions (even If they were little ones). So I begun to use Symfony2 and suddenly I fell in love with it. After 3 years of using it every day I decided to learn a bit python and django. Then I realised that it's much fast …

I'm trying to write a simple game using SDL and OpenGL. Up until now, I was using purely SDL and pixel manipulations on the framebuffer to draw lines and other shapes. However, as you would expect, that got unbearably slow as the number of objects on the screen increased. Now I tried to switch to OpenGL. The includes work fine, SDL_GL_SetAttribute works fine, and SDL_SetVideoMode works fine so long as I don't use any purely OpenGL functions. However as soon as I try to use an opengl function (that I copied from a tutorial), my compiler gives me an Undefined …

It's not often I start a new thread, but I've hit a bit of an unusual problem...Admittedly one of my own making... I have a laptop with a completely dead HD, which I've been using for a while with Ubuntu 9.10 installed on a bootable 8Gb USB stick with approx 3Gb of persistent storage. I've been using it for a little while now and everything was going rather swimmingly until I ran Bleachbit to clear some space by cleaning some of the caches, but somehow it completely borked the install so it won't boot fully.

I was trying to install java JRE7 this earlier. I followed the instructions Mike 2000 17 linkedd in another linux thread. In the installation stage of the setup it said to put this into the terminal: sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer I did that and let sudo work. It said to check to see if it sucessfully downloaded by typing this into the terminal: java -version It was supposed to say something like this: java version "1.7.0_10" Java(TM) SE Runtime Environment (build 1.7.0_10-b18) Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode) But it said …
