• Reasonable technological solutions to create CRM using .NET eventually Java

  - by user1825608

  My background(If it's too long, just skip it please ; ) ): I am Java programmer(because of demand): mostly teacher for other students, worked on few thesis for others, but during my journey I discovered that .NET and Microsoft's tools are on at least two levels higher than Java and its tools so I want to learn more about them. I programmed little bit on Windows Phone(NFC Tags, TCP Clients, guitar tuner using internal microphone, simple RSS), used WPF, integrated WPF with Windows Forms, Apple Bonjour(.NET), I have expierience with IP cameras and with unusal problems, I learn Android, but I don't like it at all. Problem: I was asked by my friend to create CRM for small new company. There will maximum 20 workers in the company working at computers in few cities in the country(Poland). They just want to store contracts with the clients and client's data. I am not sure what exacly they do but probably sell apartments so there will be at most few thousands of contracts to store in far future. Now I am totally new to CRM but I want to learn. I have few questions: Should the data be stored on a server in the company's building running 24/7 or cloud. If cloud which one? Should I use ASPX or WPF. I read one topic about it but as far as I know aspx sites can be viewed from every device with internet browser: tablets, phones(Android, WP, iOS) and computers at the same time- so the job is done once and for all(Am I right?), I don't know nothing about aspx. Can WPF be also used in manner that does not need to port it for other platforms?

• SFML - Moving a sprite on mouseclick

  - by Mike

  I want to be able to move a sprite from a current location to another based upon where the user clicks in the window. This is the code that I have: #include <SFML/Graphics.hpp> int main() { // Create the main window sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window"); // Load a sprite to display sf::Texture Image; if (!Image.LoadFromFile("cb.bmp")) return EXIT_FAILURE; sf::Sprite Sprite(Image); // Define the spead of the sprite float spriteSpeed = 200.f; // Start the game loop while (App.IsOpened()) { if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape)) App.Close(); if (sf::Mouse::IsButtonPressed(sf::Mouse::Right)) { Sprite.SetPosition(sf::Mouse::GetPosition(App).x, sf::Mouse::GetPosition(App).y); } // Clear screen App.Clear(); // Draw the sprite App.Draw(Sprite); // Update the window App.Display(); } return EXIT_SUCCESS; } But instead of just setting the position I want to use Sprite.Move() and gradually move the sprite from one position to another. The question is how? Later I plan on adding a node system into each map so I can use Dijkstra's algorithm, but I'll still need this for moving between nodes.

• Troubleshooting wireless network connectivity

  - by taserian

  I'm currently running Ubuntu 10.10, and I'm running into trouble keeping my wireless connection alive. After rebooting, I get about 5-10 minutes of a good speed connection; afterwards, the connection just zeroes out. I've gotten around to stirring up a shell script that gives me another 10 minutes or so of connectivity. Script contents below: #! /bin/bash sudo ifconfig wlan0 up echo "Enabling wireless device . . ." sleep 5 sudo iwconfig wlan0 essid MyNetworkName echo "Connecting to network. . ." sleep 10 sudo dhclient wlan0 echo "Getting IP address. . ." sleep 5 echo "Done. Closing window. . ." sleep 5 Shortly after running the line "sudo iwconfig wlan0 essid MyNetworkName" from the script, I notice the speed pick up. Other computers in my home running Windows XP are not affected by this problem, so all indications point to my Ubuntu machine. Does anyone have any pointers as to how to resolve this?

• What packages are neccessary to have sound output from java applets?

  - by MvG

  I've got a very minimalistic setup of ubuntu precise, created using debootstrap. So please don't assume that any packages are installed just because they usually are. On that system, I'd like to play some sounds from a java applet. However, this always fails with the following error message: javax.sound.midi.MidiUnavailableException: Can not open line at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1132) at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1036) ... Caused by: java.lang.IllegalArgumentException: No line matching interface SourceDataLine supporting format PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian is supported. at javax.sound.sampled.AudioSystem.getLine(AudioSystem.java:476) at javax.sound.sampled.AudioSystem.getSourceDataLine(AudioSystem.java:604) at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1066) ... 35 more As the messages mention a soft synthesizer, and pcm lines, I expect that the lack of some midi daemon is not the issue here. As far as I can tell, the alsa kernel modules are loaded, including snd_hda_intel, snd_pcm, snd_seq_midi among others. I've also included the alsa-base and alsa-utils packages in my installation. alsa-mixer looks good, using “HDA Intel PCH” as its default device. What other packages, configuration settings or daemon startups does java require to make its sound output work?

• Broad topics needed for teaching game development

  - by livingtech

  I am going to be doing a presentation on game development to an iPhone user group in the near(ish) future. My audience are iPhone developers, but not necessarily very experienced ones, and this is meant to be an introduction. My question is, what broad topics are needed to understand game development? I acknowledge that this is fairly subjective, but I really am hoping for a comprehensive list of high-level topics that apply to a broad enough swath of games that anyone interested in the topic SHOULD know about them. I would be ecstatic with some pointers to any resources that attempt to make a list such as this this. (I have looked, but my google-fu is failing me tonight.) Here's what I have so far: The Game Loop a sub-note about event driven games 2D Animation sprites/texture maps 3D Animation importance of frameworks modeling software Particles and particle effects hit detection AI Obviously I will not be covering all these topics with any depth, more like simply defining them so that after my talk, the audience will (hopefully) be able to wrap their heads around how any given game might be developed. What am I missing?

• The Differences between MAC Address and Network Layer Address

  A Mac address is a fixed number associated with a NICs onboard memory. It is initially assigned at the factory. The MAC address is broken up into 2 parts. The first part is the Block id which is six digit sequences that is unique to each vender. The second section is the device id which is created and assigned by the manufacture. A Network layer address is different because there format based on the type of protocol and network used. Also, there unique id is based on a hierarchal addressing theme on subsets of data  and narrowing it down. Just like in an address you can narrow down your house, for example: Florida, Boca Raton, 33428, SW 53th street states that you live in Florida. You also live in the area located in Florida called Boca Raton and you are also in the area of 33428 which is located in Boca Raton. Finally you live on SW 8th street which is in the area of 33428 which is located in Boca Raton which is also located in Florida.

• Difficulty / Process for mobile 2D multiplayer RPG game

  - by user2827214

  I'm looking to develop a 2D multiplayer RPG game for Android, with a bird's eye view similar to that of zelda/pokemon. The game is very simple in all ways since my intent is for thousands of players to occupy the same world which I imagine requires good performance. However, I am unsure about the performance requirements of two properties: the tile map that is used as a background is dynamic (interactive). For example, a player steps in the water, and the water turns black. Every tile in the game does this. the tile map is the same object used for all players, but it is displayed differently on each user's mobile device, even though the players exist in the same world. For example, the water that turned black is displayed as red on all other players' screens. I have knowledge of java, but almost none regarding game dev. tools. Is there a best process for these requirements? Should I develop in pure java, or use some tool like Slick2D etc.? How performance intensive are these properties, if even possible? Edit: There are no collisions in the game or difficult animations, I imagining simply changing colors of the tiles like in the examples, and a client-server architecture

• n00b needs some PHP syntax guidance [closed]

  - by Michael

  If you look at http://www.cruc.es/?paged=12/ and go to the bottom of the page you'll see the bottom navigation with the next and previous options. I've been able to make the page numbers work by changing page to paged= in the code. I don't know enough about PHP to get the previous/next options to work. Any advice would be appreciated and I've pasted the code below. Thank you: n00b if ( $query->found_posts > $query->query_vars["posts_per_page"] ) { echo '<ul class="paging">'; // Previous link? if ( $page > 1 ) { echo '<li class="previous"><a href="'.$baseURL.'/page/'.($page-1).'/'.$qs.'">previous</a></li>'; } // Loop through pages for ( $i=1; $i <= $query->max_num_pages; $i++ ) { // Current page or linked page? if ( $i == $page ) { echo '<li class="active">'.$i.'</li>'; } else { echo '<li><a href="'.$baseURL.'/?paged='.$i.'/'.$qs.'">'.$i.'</a></li>'; } } // Next link? if ( $page < $query->max_num_pages ) { echo '<li><a href="'.$baseURL.'/page/'.($page+1).'/'.$qs.'">next</a></li>'; } echo '</ul>'; }

• Updating games for iOS 6 and new iPhone/iPod Touch

  - by SundayMonday

  Say I have a game that runs full-screen on iPhone 4S and older devices. The balance of the game is just right for the 480 x 320 screen and associated aspect ratio. Now I want to update my game to run full-screen on the new iPhone/iPod Touch where the aspect ratio of the screen is different. It seems like this can be challenging for some games in terms of maintaining the "balance". For example if the extra screen space was just tacked onto the right side of Jet Pack Joyride the balance would be thrown off since the user now has more time to see and react to obstacles. Also it could be challenging in terms of code maintenance. Perhaps Jet Pack Joyride would slightly increase the speed of approaching obstacles when the game is played on newer devices. However this quickly becomes messy when extra conditional statements are added all over the code. One solution is to have some parameters that are set in once place at start-up depending on the device type. What are some strategies for updating iOS games to run on the new iPhone and iPod Touch?

• Restoring GRUB2 on Software RAID 0 after Windows 7 wiped it using LiveCD

  - by unknownthreat

  I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

• How do I fix a garbled screen on a Gateway LT3103u?

  - by paracaudex

  I've been having garbled screen problems on a Gateway LT3103u on Ubuntu for a while. I just did a fresh install of Ubuntu 11.10 and continue to have issues. I installed xubuntu-desktop in case the issues had to do with the sophisticated GNOME graphics. The problem is less bad, but it's still there. After a few minutes of using XFCE, the screen gets garbled. I assume this has something to do with the graphics card, but I don't know how to go about troubleshooting something like this. Where should I start? Update: Here is the description of the VGA card from lspci -vvv: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 028c Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: radeon Kernel modules: radeon Update: Setting GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub seems to have fixed it in both Ubuntu and xubuntu-desktop. I will test it for a day or so to see if the problems recur and then post more detail with some links to an explanation. Update 2: It is possible to use this fix for Nvidia card (GTX 260) when graphics is defective after 11.10 upgrade/install? First few restarts was graphic ok, then after few restarts begins suddenly be defective and it stay so. I must returned to 11.04 because this problem and I wait for 12.04. So I hope in this fix.

• Cannot authenticate to SBS 2003

  - by Lerp

  I am trying to connect my machine to my work's entirely windows network and I am having a few issues: Whenever I try to access the server, the authentication dialog just keeps popping back up. I cannot connect to the printers (it says connecting to device failed) I have tried setting up samba, winbind, kerberos, likewise open all to no avail. I have a feeling I am just setting them up wrong. My nautilus shows this when I go to Network Windows Network MASTERMAGNETS I can ping both MASTERMAGNETS.LOCAL and 192.168.0.2 after modifying my /etc/hosts james@jamesmaddison:~$ cat /etc/hosts 127.0.0.1 localhost jamesmaddison 192.168.0.2 MASTERMAGNETS.LOCAL 192.168.0.50 Sharp-Printer # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters I believe that's the correct domain (not sure if that's the correct term) as when I do nslookup MASTERMAGNETS.LOCAL I get the following: james@jamesmaddison:~$ nslookup MASTERMAGNETS.LOCAL Server: 192.168.0.2 Address: 192.168.0.2#53 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.3 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.2 It all worked fine before I reinstalled Ubuntu and now I just cannot get access to the server. All help is appreciated, I need to get this working or I fear I will be forced to develop in a windows environment :(

• Distributing an Android game with plugins via the market

  - by Peter Serwylo

  I'm new to Android development, and was wondering how the following could be achieved within the confines of the Android market as a distribution channel: One main application, which handles the main menu, networking, high scores, etc. Several games which can be launched from the main menu, which all work within the same eco system. The main application is not just a pseudo launcher for other games, these different games will share high scores and other achievements/preferences. In a traditional package management system such as apt, pacman or yum, this could be handled quite happily through dependencies. This does not appear to be possible via the Android market. The closest I've seen is when apps scan to check if the required app is installed, and if not, launches the market and asks the user to download the app. This sounds like a very messy solution. It also begs the question, would they download the game (plugin) first, which then downloads the main shell application? Or would they download the main shell application, and when they navigate to a menu item which says "Play game", then it scans for any installed games, and if none exist, redirects to the market? Also, I'm not even sure if it is possible to dig up the package from another application on the device, and start invoking classes from within (e.g. when you want to launch the game (plugin)) A final option is just to have a 3rd component which is a .jar that each game includes, which effectively contains the entire shell application. Then each game would appear to have the same menu, but it would become a nightmare as soon as you want to update the menu component and have to re-release each game. It would be especially worse if other people released games (plugins) based on the same framework and didn't update them. Is there any other options which I haven't thought of? Has anyone else solved this or seen a solution in any apps they've installed (doesn't have to be games)? cheers.

• Trouble with touch events on iPhone

  - by MrDatabase

  I'm making a simple 2D game for iPhone. Think of the game as a ball on the screen that goes up while the user is touching the screen and falls down when the user stops touching the screen. The ball starts moving up in touchesBegan:withEvent and starts moving down in touchesEnded:withEvent. This works fine almost all the time. However on occasion the ball will keep moving up after the user stops touching... or the ball will keep moving down while the user is touching. Why is this happening? Just fyi the ball is drawn on a UIWindow. The taps are handled by a UIImageview subclass that's clearColor and takes up the entire screen. This "touchLayer" is also moved to the front of the window in the game loop. Any idea why this control scheme occasionally fails? Perhaps the touch events just aren't firing? Or they're fired out of order? Cheers!

• SSIS Send Mail Task and ForceExecutionValue Error

  - by Kevin Shyr

  I tried to use the "ForcedExecutionValue" on several Send Mail Tasks and log the execution into a ExecValueVariable so that at the end of the package I can log into a table to say whether the data check is successful or not (by determine whether an email was sent out) I set up a Boolean variable that is accessible at the package level, then set up my Send Mail Task as the screenshot below with Boolean as my ForcedExecutionValueType.  When I run the package, I got the error described below. Just to make sure this is not another issue of SSIS having with Boolean type ( you also can't set variable value from xp_cmdshell of type Boolean), I used variables of types String, Int32, DateTime with the corresponding ForcedExecutionValueType.  The only way to get around this error, was to set my variable to type Object, but then when you try to get the value out later, the Object is null. I didn't spend enough time on this to see whether it's really a bug in SSIS or not, or is this just how Send Mail Task works.  Just want to log the error and will circle back on this later to narrow down the issue some more.  In the meantime, please share if you have run into the same problem.  The current workaround is to attach a script task at the end. Also, need to note 2 existing limitation: Data check needs to be done serially because every check needs to be inner join to a master table.  The master table has all the data in a single XML column and hence need to be retrieved with XQuery (a fundamental design flaw that needs to be changed) The next iteration will be to change this design into a FOR loop and pull out the checking query from a table somewhere with all the info needed for email task, but is being put to the back of the priority. Error Message: Error: 0xC001F009 at CountCheckBetweenODSAndCleanSchema: The type of the value being assigned to variable "User::WasErrorEmailEverSent" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object. Error: 0xC0019001 at Send Mail Task on count mismatch: The wrapper was unable to set the value of the variable specified in the ExecutionValueVariable property.   Screenshot of my Send Mail Task setup:

• Prevent Looping and Inefficient Rule Executions by C2B2

  - by JuergenKress

  This recipe, taken from the recently published Oracle SOA Suite 11g Performance Cookbook gives guidance on how to avoid rule executions that will loop, potentially indefinitely! We’ll use an inbound XML fact and a local RL fact as an example. Getting ready You’ll need access to a SOA composite containing an Oracle Business Rules component in JDeveloper to apply this recipe. We’ll assume you have an XSD schema with an input type RequestInput containing input and bonus String types, and output String value called output in a type ResponseOutput. These aren’t efficient but serve as an example. We’ll step through adding a rule to a composite and creating an RL fact. How to do it... Open a SOA composite. Right click on the Project and select Business Rules (Service Components), use the search box if it is not immediately available. Give the rule a name and click the green plus icon to add the RequestInput to the input and ResponseOutput to the output types. Read the complete article here.

• Workaround for an Xcode/iOS SDK Issue...

  - by Joe Huang

  Hi, everyone: When you are doing ADF Mobile development, and you need to deploy the application to an iOS device, you would need to compile/deploy the app with iOS App Certificates and Provisioning Profile. This means you would need to "Deploy to Package" or "Deploy to iTunes" during deployment, and configure JDeveloper with the proper certificates/profiles. In some instances (exact combination is still not clear), deploy and signing the application to generate the ipa file may fail with similar error message at the end of the deployment log: [01:04:45 PM] Deployment failed due to one or more errors returned by '/usr/bin/xcrun'. The following is a summary of the returned error(s): Command-line execution failed (Return code: 1) error: /usr/bin/codesign --force --preserve-metadata=identifier,entitlements,resource-rules --sign iPhone Distribution: Oracle Corporation --resource-rules=/var/folders/x7/21sjrpx13qj9tq20z14s3j_w0000gn/T/tkROhP11qU/Payload/HelloWorld.app/ResourceRules.plist --entitlements /var/folders/x7/21sjrpx13qj9tq20z14s3j_w0000gn/T/tkROhP11qU/entitlements_plistEINPBkIG /var/folders/x7/21sjrpx13qj9tq20z14s3j_w0000gn/T/tkROhP11qU/Payload/HelloWorld.app failed with error 1.

The workaround is discussed in this article from StackOverflow. This article refers to the old location of Xcode, so you would need to adjust the paths accordingly. The path for Xcode 4.3 and above would be like: /Applications/Xcode.app/Contents//Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/PackageApplication to this script file. To modify it, you probably can’t use Text Editor. I end up opening a terminal session, changed the file permission, and used vi to update it. Thanks, Oracle ADF Mobile Product Management Team

• Seeking solution for printing-reporting .NET

  - by Parhs

  I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

• Workflow workarounds: tracking individual column changes

  - by PeterBrunone

  This post is long overdue, but since the question keeps popping up on various SharePoint discussion lists, I figured I'd document the answer here (next time I can just post a link instead of typing the whole thing out again).In short, you cannot trigger a SharePoint workflow when a column changes; you can only use the ItemChanged event.  To get more granular, then, you need to add some extra bits.Let's say you have a list called "5K Races" with a column called StartTime, and you want to execute some actions when the StartTime value changes.  Simply perform the following steps:1)  Create an additional column (same datatype) called OldStartTime.2)  When the workflow starts, compare StartTime to OldStartTime.    a) If they are equal, then do nothing (end).    b) If they are NOT equal, proceed with your workflow.3)  If 2b, then set OldStartTime to the value of StartTime.By performing step 3, you ensure that by the end of the workflow, OldStartTime will be equal to StartTime -- this is important because the workflow will continue to run every time a particular item is changed, but by taking away the criterion that would cause the workflow to run the second time, you have avoided an endless loop situation.

• What could be causing frequent display freezes?

  - by austen

  I just installed Ubuntu 14.04 two days ago (coming from Win8) and in the two days that I've been using it, my display has frozen four or five times. The mouse won't move but the keyboard does respond so I can use the Ctrl+Alt+Bkspc command to fix it. It seems like it might just be the display freezing because one of the times I was watching a Youtube video and the audio continued playing. I have an Nvidia graphics card with the most recent Nvidia drivers for it enabled. I see that a lot of questions about Ubuntu freezing get marked as a duplicate and pretty much always linked back to a thread about what to do when it freezes. Clearly, I've got that bit figured out already and I did read that thread for further advice. What I'm looking for though is how to fix this permanently. output from lspci -nnk | grep -iA2 VGA: 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) Subsystem: Lenovo Device [17aa:2200] Kernel driver in use: i915 Update: JohnnyEnglish pointed out that Ubuntu is using the integrated graphics, not my Nvidia card. It turns out my laptop uses Nvidia Optimus and I cannot enable only the graphics card through the BIOS. I found out about Nvidia Prime and got it set up using this article. The settings panel which allows you to select the graphics says that 'performance mode' is enabled but when I check which graphics controller is enabled through the terminal, it still says it's using the integrated graphics. I'm not sure if this could be causing the freezes but I guess it's a starting point. Any ideas on how to resolve this?
