  • What .NET objects should I use to create a cookie based session in MVC?

    - by makerofthings7
    I'm writing a custom password reset application that uses a validation technique that doesn't fit cleanly with ASP.NET Membership Provider's challenge questions. Namely I need to invoke a workflow and collect information from the end user (backup phone number, email address) after the user logs in using a custom form. The only way I know to create a cookie-based session (without too much "innovation" on my part) is to use WIF. What other standard objects can I use with ASP.NET MVC to create an authenticated session that works with non-windows user stores? Ideally I can store "role" or claim information in the session object such as "admin", "departmentXadmin", "normalUser", or "restrictedUser" The workflow would look like this: User logs in with username and password If the username and pw are correct a (stateless) cookie based session is created The user gets redirected to a HTML form that allows them to enter their backup phone number (for SMS dual factor), or validate it if already set. The user can then change their password using the form provided The "forgot password" would look like this User requests OTP code to be sent to the phone User logs in using username and OTP If the OTP is valid and not expired then create a cookie based session and redirect to a form that allows password reset Show password reset form, and process results.

  • Radeon HD 6850 VMware 3D Support?

    - by Matt
    I'm a new Ubuntu user (new to all of linux actually). I've installed Ubuntu 11.10 x64 and have been enjoying it, but I wanted to see how it would perform using VMware for small time gaming since I find dual booting too much of a nuisance to even bother using Ubuntu at all (sorry!). I have an Asus EAH6850 DirectCU Radeon HD 6850 graphics card and I've installed the additional ATI/AMD proprietary FGLRX graphics driver, but when I open a Windows XP 32bit machine I installed through VMware, I get this message: "The GPU driver currently installed on this host may cause issues with VMware products. If you notice any issues please disable the 3D support in the affected virtual machines." I still have 3D capabilities in the VM but they are very very choppy even running the DX tests (the spinning cube). I've seen people on youtube and other forums saying that since the new 3D acceleration in VMware 8 gaming is very possible through VMs (and I've seen them running the DX tests with the spinning cube very smoothly). I'm wondering if my graphics card isn't fully supported or if I have installed it wrong. Also when I check system info (on the host Ubuntu machine) it says "Graphics VESA:BARTS" Should my Radeon HD 6850 be showing up there? The rest of my basic system info i5 2500k 8GB 1600MHz memory Guest is running with access to all 4 cores of processor and 3gb memory assigned.

  • Setting up Cluster Configuration using an existing web server as a Primary Node?

    - by RapidWebs
    Thanks in advance for any help which is issued! I am having a slight issue, and need help with the decision making process when it comes to setting up my Cluster Configuration, consisting on a line of Ubuntu Servers (12.04). We currently have a Primary node, which resides in the US within a Datacenter, but we are going to be using this for all serious bandwidth and resource intensive websites, and through a configuration of Virtualmin + Webmin, will be setup as a sort of pseudo-cluster, using Virtualmins Cluster Modules. Anyways, on to the issue: We also have a business line setup locally, with three servers. here are their specs: Intel P4 2.4 ghz, 1GB Ram, 110 gb sata, Ubuntu 12.04* AMD 1.3 ghz, 512MB Ram, 20 GB IDE P3 Xeon 800mhz (dual physical processors), 1GB Ram, 3 * 25 GB Raid Configuration (one in use for host operating system). The first machine is currently IN USE and is serving virtual hosts off a sub-domain. My question is this: How can I integrate the Secondary node (which will be the Primary node per say, in this smaller configuration...) which is currently in use, into the cluster configuration w/ the other two servers for: Sharing Resources Redundancy (HA?) NFS /w the two Raid Disks without having the FORMAT the secondary node, and start fresh moving all my services in to a DRBD network drive or something similar, and than restoring all active virtualmin's Virtual hosts. the idea is that I want minimal downtime to people currently being served from server2.mywebsite.com, and from what I understand, all services need to be on a NFS so that they can be mounted on demand and accessed from the other machine taking over (i.e. Heartbeat + DRBD Config.) but my issue is that i already have all these services installed to their default directory structure: how can i most easily setup this NFS and HA system, move all my desires services to this new drive, and do it with minimal down time, and without breaking Virtualmin and everything else on my server? even just some pointers, a thread i could read, or a step by step check list or run down of commands i could issue to get started would be great! thanks!

  • Technology Choice for a Client Application [on hold]

    - by AK_
    Not sure this is the right place to ask... I'm involved in the development of a new system, and now we are passing the demos stage. We need to build a proper client application. The platform we care most about is Windows, for now at least, but we would love to support other platforms, as long as it's free :-). Or at least very cheap. We anticipate two kinds of users: Occasional, coming mostly from the web. Professional, who would probably require more features, and better performance, and probably would prefer to see a native client. Our server exposes two APIs: A SOAP API, WCF behind the scenes, that supports 100% of the functionality. A small and very fast UDP + Binary API, that duplicates some of the functionality and is intended for the sake of performance for certain real-time scenarios. Our team is mostly proficient in .Net, C#, C++ development, and rather familiar with Web development (HTML, JavaScript). We are probably intending to develop two clients (for both user profiles), a web app, and a native app. Architecturally, we would like to have as many common components as possible. We would like to have several layers: Communication, Client Model, Client Logic, shared by both of the clients. We would also like to be able to add features to both clients when only the actual UI is a dual cost, and the rest is shared. We are looking at several technologies: WPF + Silverlight, Pure HTML, Flash / Flex (AIR?), Java (JavaFx?), and we are considering poking at WinRT(or whatever the proper name is). The question is which technology would you recommend and why? And which advantages or disadvantages will it have regarding our requirements?

  • 12.04 wired network doesn't work RTL8111/8168B

    - by laket
    its a fresh 12.04 install 64bits. wifi works fine, wired stays off with cable connected and network-manager shows as if cable is disconnected. Turning off networking lights up my network-cards leds, turning networking on shuts off the leds and no communication is possible. I already tried, turning off the network-manager (sudo service network-manager stop) and setting up my eth0 manually, as soon as I switch off the network-manager my leds light up, but after setting up manually eth0 (sudo ifconfig eth0 10.2.10.114 netmask 255.255.0.0 up) the leds turn off again.

  • Visual Studio 2010 editor painfully slow

    - by Daniel Gehriger
    I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

  • Change order of monitors without changing fullscreen"size"

    - by user171489
    I have a dual monitor setup. My primary monitor is a 22" with a max resolution of 1680x1050 and my secondary is a 19" with a max resolution of 1280x1024. The secondary is standing on the left side of the primary one. My problem now is, that, if I change the order of the monitors in my nvidia x-server settings, so that my secondary is the first one (or the one on the left), the fullscreen mode in flash in scaled up to my secondary monitor, even if it´s displayed on my primary one. Meaning that i get a 1280x1024 "fullscreen" window on my bigger primary monitor. When I configure my x-server settings so the secondary monitor is the one on the right, I don´t have this problem. The only thing then is, that I have to scroll out on the right to get to my monitor on the right. I can´t move my secondary monitor on the right side of my primary due to lack of space and my belief that there must be a software solution. ;) Thanks in advance.

  • Can't install Ubuntu, black screen after install

  • Impossible to enable bluetooth under Ubuntu

    - by PCh
    I just installed Ubuntu 12.04 (dual boot, kept Windows just in case) on my new Acer Aspire One 756-877. As soon as I installed it I also installed the Broadcom driver, since wifi wasn't working, and that solved it right away. But when I tried Bluetooth, I had a problem that I see is quite recurring: -The hardware is on (and working fine under Windows) -The icon shows up on the menu, giving me the options of turning Bluetooth on or off, and then just "Bluetooth preferences". -I can apparently turn it on that way, which only lights up the icon but makes no difference at all (and doesn't give any other options in the Bluetooth menu) -When I open "Bluetooth preferences" (whether Bluetooth is apparently on or off, it makes no difference), it says it's disabled and will not let me slide the button to enable it. I've rebooted, but nothing happens. -The material is Broadcom and the port (if it's relevant at all) is Port_#0001.Hub_#0003 I tried the following commands suggested in other similar questions, with no result at all: sudo dmesg | grep blue and sudo service bluetooth start and sudo /etc/init.d/bluetooth start Any other clues on what I can do? Thanks for your time!

  • Unable to install ubuntu on a AMD 64 bit system with a AMD Radeon HD 6670 graphics card

    - by Tom Wingrove
    I’ve been running a dual boot system (Ubuntu/Windows7) for two years or so with no problems. I recently built an AMD 64 Bit System, re-installed Windows but when I went to load Ubuntu inside Windows, hit a snag. The screen view during installation became small square blocks of colour, which obviously is a graphics drive problem. I tried various live disks both 32 & 64 bit for, Ubuntu 12.04, 11.10 & 10.10, all but Ubuntu 10.10 had the same problem. Ubuntu 10.10 loaded ok, installed the presented ATI graphics driver as usual but was left with the AMD Unsupported watermark at the bottom right of the screen. The graphics card installed in the computer is an MSI ATI Radeon HD 6670 (in effect an AMD Radeon HD 6670). I am fairly new to linux and while I can install and tweak the OS, I am rather baffled as to what to do. So my question is will an up to date ATI Driver be released in the near future for installation/live disks? Or am I going to have to downgrade my graphics card to use linux? Yours Tom Wingrove

  • Cannot access personal website from home IP. More details inside.

    - by GX67
    This is a recent problem I've been having. My site can be accessed from almost everywhere else except from my home IP, where I do most of my editing/updating, etc. I've tested my connection from my school's network, a friend's connection from out of state (multiple states), and through a tethered connection with my friend's Android. It works in all those cases, both viewing, accessing the cPanel, and using FTP. Here's the problem that happens to me when I try to view it from my home IP: The page times out in Firefox, IE, and Chrome. Using the cmd, I ran tracert and ping, both as failed attempts. Log here. downforeveryoneorjustme.com says my site is up. So do the other site checkers. I can't access my cPanel or FTP accounts. I can't access the host site. (I use perfectz.info for hosting, and I can't access their site either.) System settings: No firewall enabled. Ports are seemingly properly forwarded. (e.g. The ports are open in the router settings, and are open everywhere else.) I have an email forwarder set up from the cPanel that works just fine. (i.e. I can receive emails sent to that address. If any other information is needed, I'll do my best to provide it. UPDATE @ilhan: I use two things: 1) The site cPanel from in-browser. 2) Dreamweaver CS5 FTP. @Matthias: I tested both, and it passes the dual stack with a 10/10. What should I do then?

  • xorg-edgers PPA with llvmpipe breaks AMD APU system

    - by linux_RRT
    I've read before where this had happened to another user with the same system... I was running Ubuntu 12.04 LTS with Kernel 3.2.0.29 and decided to give xorg-edgers a try. I purged fglrx* and xorg* before beginning. I upgraded with sudo apt-get upgrade -d The system downloaded and installed 109MB worth of data to the system, including llvmpipe which I am very unfamiliar with, and Kernel 3.5.0.11. The system was then rebooted to finalize the upgrade. The system boots to a black screen and then tells me "The system is running in low-graphics mode". Did I miss a step in the install? Or do the newest open-source drivers just not work with my hardware? I realize this hardware (APU) is some of the newer development. I dropped to command via the fallback menu and attempted to boot lightdm as root, but the system hangs in 'Configuring kernel parameters' at Starting initializes zram swaping. ...and then it just sits there. The other thing that concerns me is the output at the top of the screen that says: could not write bytes: Broken pipe Does llvmpipe work for this type of system? To be clear the system is: MSI x370-206us Laptop Radeon HD 6320 AMD e450 APU 1.67ghz dual-core Any help would be much appreciated. Like I said, I'm pretty sure I followed the right order of operations for the install procedure, but I was curious if anyone with similar hardware had experienced anything similar.

  • How to efficiently protect part of an application with a license

    - by Patrick
    I am working on an application that has many functional parts. When a customer buys the application, he buys the standard functionality, but he can also buy some additional elements of the application for an additional price. All of the elements are part of the same application executable. A license key is used to indicate which of the elements should be accessible in the application. Some of the elements can be easily disabled if the user didn't pay for it. These are typically the modules that you can access via the application's menu. However, some elements give more problems: What if a part of the data model is related to an optional part? Do I build up these data structures in my application so the rest of my application can just assume they're always there? Or do I don't build them, and add checks in the rest of may application? What if some optional part is still useful to perform some internal tasks, but I don't want to expose it to the user externally? What if the marketing responsible wants to make a standard part now an optional part? In all of my application I assume that that part is present, but if it becomes optional, I should add checks on it everywhere in the application. I have some ideas on how to solve some of the problems (e.g. interfaces with dual implementations: one working implementation, and one that is activated if the optional part is not activated). Do you know of any patterns that can be used to solve this kind of problem? Or do you have any suggestions on how to handle this licensing problem? Thanks.

  • IPv6 tunnels - any easy way to turn them on and off?

    - by Rob Hoare
    I've set up a tunnelbroker.net (Hurricane Electric) IPv6 tunnel from my laptop running 12.04. Works fine, and allows me to test the dual-stack configuration on my remote webservers etc. until native IPv6 is available on my ISP. However, there are times when I don't want the tunnel. For example if I'm accessing something that requires an IPv4 address in my own country rather than the Tunnelbroker tunnel endpoint, or if I'm away from the local IPv4 tunnel endpoint, or if I simply want to test without IPv6. Is there a simple way to disable and then re-enable the IPv6 tunnel, without rebooting? For context, here's what's in my /etc/network/interfaces (NNN replaces numbers): auto he-ipv6 iface he-ipv6 inet6 v4tunnel endpoint 216.218.NNN.NNN address 2001:470:NNN:NNN::2 netmask 64 up ip -6 route add default dev he-ipv6 down ip -6 route del default dev he-ipv6 Is there a network manager application (gui or command line) to selectively enable/disable parts of /etc/network/interfaces, or IPv6 in general? I found even by commenting out that out (and reloading networking) it's tough to get the IPv6 to go away. A "tunnel on/off" button in networking would be great, like using a VPN.

  • 11.10 liveCD black screen

    - by Shaun Killingbeck
    Attempting to install/try ubuntu 11.10 on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. I have caught a glimpse of some output to do with pulseaudio and [fail], but I can't imagine why that would cause a screen problem and the sound definitely works anyway.

  • Further question on Intel graphics driver

    - by Thomas Byers
    Ok, Josh answered almost immed.! I need to know specifically, now that I am using Nvidia card effectively, do I need to allow update manager to update the intel gr. drivers? I must add, I believe I know why Update Manager is telling me I need to update those Intel gr. drivers. It probably happened because I tried to update my nvidia drivers and got a buggy install, which let to to a black screen. I shut the system down manually after that and rebooted to a black screen and upon a further reboot I ascertained that I could still dual-boot(windows 7) into the other os. Then I went through the restart process and at the grub2 menu chose other options and it was probably, at that time, that Linux was smart enough to know that nvidia drivers as installed weren't cutting it, and reverted to the onboard Intel graphics system...does that make sense? Anyway, after successfully getting up and running, I reinstalled my old but successful nvidia drivers and all was well again, except now upon running Update Manager, I am offered the Intel graphics driver upgrade each time, which, up til now I have unchecked...my question is now more obvious. Should I accept the Intel driver update and if I do, will it once again override my nvidia drivers?

  • Difficulty Mounting Volumes on a Partitioned External HD

    - by Todd
    I'm having a great deal of difficulty with an external hard drive. I'm currently running a dual boot system (XP Service Pack 3 and Ubuntu 11.04 Natty Narwahl) on a Dell Inspiron B120. I'm trying to set up a new 80 GB Hitachi external HD. Using GParted, I formatted the drive and set up the partitions. The partitioning scheme is as follows 10GB NTFS Primary, 2GB Linux-Swap Primary, 50GB FAT32 Primary, 12GB Unallocated. After applying those changes, I went into Disk Utility and the HD appears along with the correct partitions. When I try to mount the volumes for partitions 1 and 3, I get a pop-up stating: Error Mounting Volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. When I try to to check the filesystem I get a pop-up stating: Error Checking filesystem on volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. Throughout the time that I'm attempting to troubleshoot the problem, the external drive light is on and blinking. With my frustration hitting a boiling point, I try to shut down the drive and remove it so that I can plug in a different external HD that works PERFECTLY. However, when I try to shut down and safely remove the drive, I get a pop-up stating: Error Detaching Drive An error occurred while performing an operation on "80GB Hard Disk" (HTS548080m9AT00): The daemon is being inhibited. Can anyone tell me what I'm doing wrong? I'm a newbie and not that skilled with terminal commands, so please dumb it down for me if you request specific command output.

  • Effect of using dedicated NVidia card instead of Intel HD4000

    - by Sman789
    Short version: Can someone please advise me of the effect of adding a dedicated NVIDIA GeForce GT 630M card to an Ubuntu laptop in terms of power consumption and performance gains/losses when doing general productivity tasks and booting up. Also, how good are the closed source, open source, and Bumblebee drivers for these newer cards compared to support for the Intel HD4000? Long version/Background, if any info here is helpful: I'm thinking of ordering a laptop from PC Specialist (a UK company who actually sell machines without Windows pre-installed) with the following specifications: Genesis IV: 15.6" AUO Matte 95% Gamut LED Widescreen (1920x1080) Intel® Core™i5 Dual Core Mobile Processor i5-3210M (2.50GHz) 3MB 4GB SAMSUNG 1600MHz SODIMM DDR3 MEMORY (1 x 4GB) 120GB INTEL® 520 SERIES SSD, SATA 6 Gb/s (upto 550MB/sR | 520MB/sW) Intel 2 Channel High Definition Audio + MIC/Headphone Jack GIGABIT LAN & WIRELESS INTEL® N135 802.11N (150Mbps) + BLUETOOTH Now, as I want this laptop mainly for work and not for games, I would be more than content with the HD4000 integrated chip which comes with the processor. However, for compatibility reasons, I am not able to get the specs I want unless I choose a NVIDIA GeForce GT 630M 1GB graphics card, which I don't have a great deal of use for. I'm willing to buy it, however, as it's still cheaper than any other laptop with the specs I want. However, I know that Linux power management isn't fantastic with open-source graphics drivers, and I don't much about Bumblebee. Basically, whilst I'm happy to 'tolerate' the card being there, I don't want to experience any negative effects on the rest of my system (battery, performance etc) and if there are likely to be any, I might reconsider my purchase. So if anyone can advise me on the effects, I would be very grateful, since I doubt I can just turn the card off. Thankyou for any assistance :)

  • Multiple displays using AMD drivers

    - by Halik
    I am currently running a dual display setup with nVidia 8800GTS video card, on a Ubuntu 12.10 box. The current setup uses nVidia TwinView to render the image on a 1920x1200 display and 1600x1200 one. I'm planning to add a third, 1280x1024 display to the setup. The change will require me to upgrade my GFX card to one supporting triple displays. I'll probably go with Sapphire Radeon 7770 (FLEX edition, to avoid additional active DP-DVI adapters). Before I invest in new GFX I wanted to ask - how well the AMD drivers will support such a setup. It does not matter whether it's fglrx or the OSS ones. If I remember correctly, when running Fedora on a Radeon x800, I had 'void' areas above and below the working area on my second display. The desktop was rendered in 1920+1280 width and 1200 height (which left 176px of vertical space accessible for my cursor and windows but not displayed on the screen - I'd prefer to avoid that). It may have very well been my misconfiguration back then. Generally, are there any solutions from AMD on par with TwinView? Or is it a non-issue at all? Also, I'm wondering about the usual stuff - hardware h264 decoding support, glitch-free flash support, any issues with Compiz/Unity?

  • How do I know if I'm getting the most out of my video card?

    - by b.long
    My computer at home is a bit lacking, so I want to make sure I'm getting the most out of it while I can. Generally speaking, here are the specs: 4GB Memory AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ × 2 64-bit Ubuntu The terminal shows me the following: me@home:~$ uname -a Linux home 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux me@home:~$ lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] me@home:~$ sudo lshw -C video *-display:0 description: VGA compatible controller product: RV380 [Radeon X600 (PCIE)] vendor: ATI Technologies Inc physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:44 memory:e0000000-efffffff ioport:ac00(size=256) memory:fdef0000-fdefffff memory:fdec0000-fdedffff *-display:1 UNCLAIMED description: Display controller product: RV380 [Radeon X600] vendor: ATI Technologies Inc physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress bus_master cap_list configuration: latency=0 resources: memory:fdee0000-fdeeffff me@home:~$ lspci -nn | grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] [1002:5b62] The additional drivers menu in System Settings shows me nothing useful and my attempt at installing ATI's Catalyst Control center (drivers that came with the video card) failed. I believe the latest version of Ubuntu at the time was 9.x. What should I do? Install an old version of Ubuntu 9? Use some alternative driver? UPDATE: I might try my hand at a bit from this answer next: "Installing Catalyst Manually (from AMD/ATI's site)" . From a terminal, fgl_glxgears returns *"fgl_glxgears: command not found"*. Any thoughts?

  • Native AAA games coming to Ubuntu. Where they will be installed?

    - by user86274
    Many users use SSD disks (and I believe many more in the future) for their OS. 128GB SSD disks are common place nowadays and many users (like me) use their SSD for dual booting (Windows and Ubuntu). Ubuntu installations like this occupies 20-40 GB (/ , /home and swap). Up to now there was no problem. In a few weeks though, triple A games are coming to Ubuntu (i.e. l4d2) that require probably tens of GB for installation. In windows there is no problem, because you can install a game anywhere you want (i.e. I install games in D:/Games/). In Ubuntu, though, programs install files in many places (i.e. /usr/* , /lib, /etc ) so from what I remember, I never had the option to choose where to install a program. So, how will it be possible to install AAA games that require many GBs, when our Ubuntu installations won't have the necessary space? Could a /opt mounted on a mechanical disk (HDD) be the solution? Is it something I am missing?
