  1. That just disables memory checking at boot time, more of a "user preference" than anything to worry about. Just have fun poking around in Mint, it's quite nice IMHO.
  2. Two potential issues: Your virtualisation is switched off, don't worry about changing it, just be aware it's off if you ever want to use VMM, and switch it on then (VMM works OTB in Mint). S5 sleep state is off. It's kind of a corner use case in which people NEED it, but I find it useful.
  3. Just as a point of interest, when connecting two devices (as in your 5G router to the ER-x) where no other devices will ever be introduced, I use /30 network addresses to do so. In your example I'd assign 192.168.AAA.0/30 between these two so: 192.168.AAA.0 is the network address 192.168.AAA.1 is the Modem address 192.168.AAA.2 is the ER-X address 192.168.AAA.3 is the broadcast address If you wanted to be at the other end of the /24 address range: 192.168.AAA.252 is the network address 192.168.AAA.253 is the Modem address 192.168.AAA.254 is the ER-X address 192.168.AAA.255 is the broadcast address
  4. Like I said, it can be moot anyway. The only difference would be when you are masquerading/overloading, the router is "creating" DNAT/SNAT rules on the fly and remembering where each one "points to". For example (in a standard single router set-up) your phone sends an http request to google.com from ip 10.0.0.2:[some port], this ends up on your routers LAN interface and it forwards the request via it's WAN interface, this is when the SNAT rule is applied, so google gets a request from an address it can actually reach (re: not a private class a|b|c) . When it comes back from google the DNAT rule starts playing a part, first it looks up who the request is for in it's "masquerade table" and DNAT is applied to the reply so it gets back to your phone. This needs to be "dynamic" as, if your pc was to make a request to google.com at the same time we don't want to be sending the packets back to the wrong device. In your case the ER-X can't "send them back" to the wrong device, as it's always being sent back to the gryphon router which does the actual connection tracking/masquerading for the LAN network address(es). So if you consider that with a single DNAT/SNAT pair of rules you can create a situation where every possible dynamic DNAT/SNAT pair can be replicated without the overhead of [finding the right rule/looking up the right rule] you **might** experience lower latency << But this depends on how the UI manifests the rules you have asked to be created within the routing software (I would *expect* Ubiquity to do it "properly", especially in the case of the ER-X, but they are (IME) one of these borderline mfgrs that sometimes leave me thinking "G*d d*mn Ubi, I thought you'd do that properly!"). If the ER-X UI made it difficult for *me* to enter the SNAT rule in my mind i wanted to enter, and I wasn't having latency issues, I'd probably be "F*ck you then!" and leave it masquerading (or look into it's "DMZ" capabilities, 'cos I'm a stubborn b*stard). Similar principles apply to the NAT rules on the 5G modem, as it's always sending packets on the LAN side to the same address, the ER-X. Once your packets leave from your WAN address, all sorts of routing happens within your ISP's own network space before it reaches the big bad internet space (where even more goes on), but as none of this is [stateful/involves NAT contracking] the added latency is negligible: Ideally this is the kind of routing you would be doing within your own network, but so many consumer grade routers assume they are "the only router in the village" you can't turn off NAT, as you have experienced.
  5. You'll need SNAT but masquerade/overload is overkill, but the only issue you'll have is latency, but if it isn't being effected by the the connection tracking then it's moot really. Well, if you don't plug into the WAN port it kind of is disabled, it's just a fancy switch with an AP and bunch of unused routing protocols, but then your masquerade/overload would need to be on the ubiquity router, and the gateway of last resort offered up with DHCP leases (assuming that the server stays on the Gryphon) would have to point to the actual gateway (re: the LAN IP of ER-X) Depends if you are asking them both to route or not, something will shit the bed if there are "different networks" with the same network address though. If that 5G modem has to route, then it has to NAT, but it doesn't have to masquerade or owt a static SNAT rule will suffice, everything goes to the ER-X on a single IP, as does the (bridge mode?) modem. It's The gryphon that is superfluous in this set-up, and You can just side step it by not letting it route.
  6. Because it's considered and external disk by gtk/gnome apps; either use an app that lets you take more control (like qdirstat), or trick the app you are using into displaying it...
  7. qdirstat has always been my `goto` program for directory use analysis, I'd be quite surprised if you can't find a copy in an arch repo. There may be a hard coded filter on /run/media/* as this would be the default location for removable media, not considered part of your computers "hard disks". Bind mounting the sd card to a point in /mnt/ should fix this if it's the cause: sudo -i || sudo su || su mkdir /mnt/sdcard mount /run/media/mmcblk0p1 /mnt/sdcard --bind #and to undo/clean up this umount /mnt/sdcard rmdir /mnt/sdcard *IF* is is the cause /mnt/sdcard should show up as a drive option in your disk analysis software, and show under "devices" in dolphin (doesn't work that way without interaction in other file managers IME)
  8. You often can't without unplugging the "undesirable" display at boot time. The (video?) bios will have a "order of preference" with which it presents available displays to the "output curator"; if the legacy displays (via DP) are presented first these will be chosen by default as your bios display(s). IF you can switch your HDMI monitor to a DP>>HDMI "adaptor" cable, it *might* produce a bios output on both monitors, but YMMV. EDIT: Booting with a linux live USB/CD and carefully analysing the display software output logs might give insight as to which displays "take precedence" (but again YMMV, because nvidia), but without becoming a firmware "hacker", this is purely an information gathering exercise...
  9. TBPH, you should play with CentOS. It was the RedHat "public" clones that gave me a easy foothold into a server environment with a "friendly UI" (even if it was text based ATT) some 20 odd years ago, it's their bread and butter. As far as I can tell the "ubuntu server" paradigm is for people with an understanding of the "ubuntu backend system", who need to run a server, and their are more "1st time user friendly" distros out there for server management. Yes, you can install "server" programs on a buntu desktop, but your "attack surface" is becoming un-necessarily large by doing so. My advice would be to find a distro with a "stable" Webmin package in it's repositories - Webmin is a perl/web based "server management hub", and it allows you to use a fairly intuitive, pretty ubiquitous interface to manage most popular "server" software across many different distros, without having to install some kind of graphical front end on the "server itself", as your client browser does all the "heavy" lifting with regards to the UI. EDIT: Compiz is very dated, or very new*, either way it's not something that is desirable to be to running on a server. *It died some years ago, and was VERY recently resurrected, but it's still in the "mostly undead" phase of development...
  10. Indeed. Forum rules prevent me from going into minute detail, but there are 3rd party tools that will extract all your "windows licenses" from installed software and present them in such a way as to be able to let you reuse them, but they often fall into the category of "malware" as far is windows defender is concerned. If you want to just swap out the HDD, then yeah, when you put it back and as far as doze is concerned you just haven't booted in a while. If looks could kill, my X220 just committed homicide. That aside, I've breathed life into apparently ageing hardware using Linux many times, my server is an old (and it's only just starting to show) 2.6G Xeon r200 with (originally) 2Gig of ram, but it's headless so it's very insulated from "modern desktop bloat". As your machine ages, if you are mindful of what software you use under Linux, it does so like a fine wine and just gets faster as software becomes more optimised and updated. Last bit of advice; function over form: You have to go very deep into the "minimalist" rabbit hole before you don't have the tools to make any Linux based desktop look aesthetically pleasing to you, but it is a consideration, as post major upgrade you may find yourself having to make it "look nice" again. So if you found that XDE and YDE were both good for your workflow, and you found them both intuitive enough that your little sister/niece could use it to show your her holiday videos, but YDE looked nicer, that's a fair choice. Conversely to swim upstream into a DE you don't find friendly just because the alternates don't float your aesthetic boat is a bit short sighted. Read: Making it look nice is normally easier than adding functionality. Fortunately your machine is of an age you can expect hardware to be "it just works" levels of supported (especially from that mfgr too!) that you could slap Debian on it, and install almost all the desktop environments on offer to see which is the best fit FOR YOU. Personally, I think gnome sucks huge putrefied donkey b*lls, but I'd never malign someone for running and using it (well, not much), because that's the choice they have made and their reasons behind that choice are not going to be the same as mine. Just play around with different desktop environments in Debian without the committal to running it "full time", then once you have narrowed it down to "X or Y", find some distro that focuses on that and maybe benefit from the "latest and greatest" upgrades offered for that DE, or don't because again the choice is yours. EDIT: Don't equate live CD/USB "performance" with live system performance, they aren't always correlative, in fact some "lagging" during LiveCD boot is normally indicative of distro devs "covering all the angles" instead of just dumping you to an error prompt if/when things go wrong. In this vein, reinstalling isn't usually the way to fix things in Linux, it's just a way of kicking the can down the road until the issue re-emerges, learn what the problem is and learn how to fix it, then continue your journey, don't start again...
  11. LVM would me more appropriate than raid 0 in this use case, you used to be able to do LVM from some installers, I think debian, centos and *buntu server still can.
  12. That would suggest your `linux firmware` is out of date. You can search for instructions to extract the firmware from the windows package and dump it over the top of your existing files until an update arrives, or find the upstream source your devs use and install it from there.
  13. Be sure to set-up any "new" controllers in the "big picture" , "desktop" and "chord" sections of steam, this is where you can weed out any undesirable behaviour that may happen by default by turning lots of things off. The whole "steam input" thing basically hides your actual controller from games, and gives it access to a "virtual xbox*" controller - this may be where this "dual input" behaviour is coming from. *This is really annoying, as you always get X,Y,A,B prompts and not Sq,Cir,Tri,X in some games
  14. Sounds like some kind of cookie manager is deleting things after a set period. If you can't find an addon/extension doing this, get one, and turn off any cookie management in Chrome's settings and let the addon handle it.
  15. There used to be a `visual basic` macro editor you had access to in Excel, you could populate the sheet with this, but the last time I wrote anything for Excel was in about 2008, so maybe googling "Excel VBA macro" will give some up to date instruction...
  16. Yeah, it's just hiding the password you type in. It'll ask you to confirm by typing it again after you press enter.
  17. You haven't accidentally done anything odd like turning on raid or owt, and the "alternative" sata ports are switched on?
  18. eTc not ect, just use this grep -q 'root:!:' /etc/shadow && passwd root
  19. That only matters if you are trying to reach the management interface.
  20. I didn't open any terminal in the USB environment, just the gparted shrink.
  21. No, just 2: one for linux (/) and one for home (/home). All the files to make OBS and kdenlive work will end up in /, and they are only small*, all the files that you use them to work on will end up in /home or /mnt/storage. 200G for linux is enough, I run mine on that and I have ~2000 packages installed, chroots for other systems laying around at ~15gig each and I'm still less than 1/2 used. $ cat /var/db/pkg/{kde-apps/kdenlive*,media-video/obs-studio*}/SIZE 70757998 17002513 *So less than 100meg used between them.
  22. For what you are planning, creating the isolation between / and /home is enough. OBS and kdenlive don't need much space of their own to exist, or even operate, it's only the files you create and alter that need space, those files automatically end up in your home directory. Yes and no, you can grow live partitions and filesystems, but not shrink them. You can do it other ways, but this is safest.
  23. It was fine, prediction false. The video is up. I used the mint live CD to do the shrink because I figured you already have one that works :P.
