Recently in the DC: Dell says "well you can install Debian, but then you can't have support" xD

Always funky to work in the DC x)
Are you talking about the Dell Community? Developer Community?
 
...Dell says "well you can install Debian, but then you can't have support"...

That's a topic which made me curious considering i've recently purchased one of their Inspiron 15 3520.

Install? Inside MicroSoft's new cage called the 'Windows Subsystem for Linux' (WSL) perhaps?!...

Well, initially i found it was necessary to be polite with Win11 Fam "S", which refused to let me resize its partition on my NVMe drive at first... BitLocker was in the way it seemed, while total removal remains a non-option until a feature as screen mirroring is finally supported by Linux too, eventually. So i run it once in a while to let it do its thing, but not too often, really!

:rolleyes:

Is there a way to disable Bitlocker in the BIOS?

Maybe helpful:
Code:
$ apt-cache search bitlocker
dislocker - read/write encrypted BitLocker volumes
libdislocker0-dev - read/write encrypted BitLocker volumes (development files)
libdislocker0.7t64 - read/write encrypted BitLocker volumes (shared library)
libbde-dev - BitLocker Drive Encryption access library -- development files
libbde-utils - Tools to access the BitLocker Drive Encryption format.
libbde1t64 - BitLocker Drive Encryption access library
python3-libbde - BitLocker Drive Encryption access library -- Python 3 bindings

Well, "polite" means i performed the un-bitlocking via Windows exclusively, switching to Linux only after the partition had been reduced and a reboot still using Windows would happen to agree. Ah, and while i think of it i also saved my keys before touching anything...

Back to the announced topic, sorry for my side-comment, yet i'd point out the new Dell NetBook doesn't display on my large screen at boot time, while i have another unit connected to that very same monitor which does - so it's not the screen being faulty while there's Intel inside both machines anyway! When i search my uEFi BiOS no mirror/twin screen options are to be found as if i got no HDMi port for external DP monitors, which defeats BOOT MENUs if looking from a distance, as in TV applications... If it "works" for one Intel PC and not the other what does it leave except Dell precisely?

... :oops:

I've also noticed a lot of failures related to its "h2c" something... That would be about WiFi/Bluetooth and it turns out i've experienced difficulties pairing my headphones. The chip is from Realtek apparently, then again what's left to blame if not the glue inbetween!

In addition, it now seems like i'll have to check for thermal protection too, just in case. What next? Ubuntu-certified, really??

:eek:

Euh... If i were Dell i'd tell my employees to be more careful distributing blames.

Are you in a dual boot Linux and Windows?
Which partition was reduced?

Realtek in some cases with Linux I've experienced difficulty in getting the right driver loaded as the wrong driver was loading first. To fix the problem I blacklisted the wrong driver and upon rebooting had success with the wifi connection.

Our member @Brickwizard is good with the Realtek stuff.

Tho there isn't a way for twin screen options in your BIOS there may be a way to create a config file to rectify that.
Sorry I'm not well versed with that at this time.
 
Which partition was reduced?

The 3rd one, entirely devoted to Win11 (1p3):

Dell-Inspiron-15-3520-GParted-AFTER-430x480.png


...I blacklisted the wrong driver...

Sounds like advice i might want to keep in mind! But i'm afraid nothing can embelish the sort of dull experience i had with Dell so far, downloading Ubuntu Cinnamon only reminded me it now insists to NOT ignore my exclusive Win11 'ESP' partition even if i chose the manual mode to stay in command... The one relaxing install i got was from Sparky 8 using Calamares 3.3.6 - which actually remembers the fields i'd keep filling up with others gone amnesic within a very same instance! Yet in the end it seems none of both (including a few flavours) could compensate for such ever-lasting coïtus-interruptus: it's 10 days old already and counting! But i'm collecting HardInfo2 reports each time i manage to get the iP-TV + BT earphones working long enough for the test to finish.

Tho there isn't a way for twin screen options in your BIOS there may be a way to create a config file to rectify that.

Sure, with a 2 GB partition dedicated to Dell alone i can only imagine what's possible, like to adopt 'rEFind' that has large icons conveniently aligned in a dynamic menu capable of finding ISOs on my USB drive too... But no. My other machine been running Mint for months with no oddities as i've witnessed recently, though its kernel ain't v6 so far. Maybe that's a hint of solution, i'm still in a preliminary phase trying to decide what i like best as a set of trade-offs and being blind at boot time or having to deceipher microscopic characters wasn't in my plans, initially!

Windows may have to fall out of support before Linux picks up, similar to my previous tablet that died before i had a fair return for my years of trouble. At least it was only an Atom CherryTrail, its eMMC was some culprit while the transition to NMVe/SATA3 speeds had given me hopes of improvement. It change to an i3, so why am i feeling like moon-walking?

Better news next week i guess! ;)
 
It change to an i3
A modern intel development, solid reliable BUT still very much considered an entry level CPU for laptops, [to give you some idea the I3-1005G1 from 2019/20 has a similar performance as the i5-6300U, from early 2015]
 
Our member @Brickwizard is good with the Realtek stuff.
OK so this is not specific to any make of wi-fi,
If you are installing Linux in a VM/VB [or using WSL] then all control over the external connection to the internet will be controlled by the host [windows in this case] OS., to give a VM/VB it own direct access, you need to change the parameters of the USB controller in the VM, and use a second usb dongle.

this also applies to all but with a leaning to RTL
If you are multi booting, then each OS will control it own access, this is where the problem comes with Realteck, A particular chip set will have a number say for example RTL8808 it will then have suffixes CE,US, CUE, or whatever, these letters denote the setup of the chipset and in some cases region specific, you must make sure you get the full correct driver for best results.
Using inxi from the terminal run inxi -Nn the report would normally give
Device 1 [usually the Ethernet controller]
Device 2 [usually wi-fi]
Device 3 [usually Blue tooth]
under each it should show state up or down, and the drivers installed, we need all this information to check if the correct chipset drivers [or the best available] are installed
 
Additional info

Legacy drivers for the 8723du may still be available, make sure secure boot is turned off ,you could try

sudo add-apt-repository ppa:kelebek333/kablosuz

sudo apt update

sudo apt install rtl8723du-dkms

reboot
 
« If it ain't broke don't fix it. »

I wish! :rolleyes:

« If you can't fix it don't break it. You reap what you tweak. »

There's a trap hidden in every corner indeed. :eek:

...

Data collection goes on, quite patiently, e.g. much slower than initially planned. At least it's clear the processor chip is a 12th generation Intel Core i3-1215U (e.g. with 2 more "cores" than my Atom had, with subtle nuances it seems).

An Intel 9462 chip was initially expected, instead i got some Realtek substitute supported by 'rtw88' (802.11ac) drivers including 'btrtl' - v0.1 for BlueTooth, not 1.0...

In any case the mere fact that [Fn] + [F8] effectively switches between my internal and external displays BEFORE the bootloader even took over simply tells me the odd Dell' uEFi BiOS ain't only about some driver issues anyway: this is the result of yet another poor (programmer) choice considering such "fix" only happens to be temporary - ah, and lets not waste time testing it on auxiliary keyboards for some mystery reason!

In other words that's no fault by Intel, not even the hardware manufacturer i think. Windows performance in terms of iP-TV & BT sound sessions proven solid (so far...) as i can move around without a glitch; last evening for example i was able to watch a full program via XUbuntu but a change of channel alone threatened that ellusive moment of serenity i'm afraid.

Besides the "logical" decisions i find my previous fanless tablet didn't depend on keeping it deployed at all times. In comparison Dell's Inspiron top-fins get actually blocked if its display just stands at an angle, to clear my view on the larger screen right behind. The Atom had its power button on the edge, now there's no way to use this replacement "NoteBook" without opening completely - with [F8] far away where i can't ready it's grey/obscure label. Definitely not Intel's legacy.


P.S.: I took note of the « inxi -Nn » advice even if that wasn't addressed to me. Thanks.

LOL!

Has the amount of time passed to get a refund for this laptop that you recently purchased?
 
Has the amount of time passed to get a refund for this laptop that you recently purchased?

It arrived swiftly, ~2 weeks ago. Yet if i were Dell i'd only need to argue that Windows 11 Fam "S" is working as they expect. It turns out Dell would be correct, as long as i used Windows my favourite VLC application and BlueTooth earphones it provided me solid performance (i could move, even away), so my displeasure is of another nature.

Although i recently noticed some mention relative to temperature sensors in Dell's « SMBiOS », as they call it i tink, i've chosen to ignore it so far. It's the claim of Linux friendliness that makes me want to stick to the announced titled somewhat further and address blames where it's due, with nuance as i found out (in the case of my Inspiron 15 3520) that its top-fins also serve as audio reflectors, similar to flip-phones in the '80s except it worked in reverse with a tiny microphone. This NetBook also needs its wings to deploy fully, like a butterfly otherwise i can hardly breath - and now that's time to make my point: why then keep an SMBiOS option to turn Off the lid-switch if i can't close my cover just as when using the former fanless tablet/transformer - one that never actually had its touchscreen active after deleting all traces of Windows 10 (before Win10 dumped me)...

Euh... IMO it all boils down to my impression of pre-existing capabilities basically disabled, to be re-enabled later if "lucky". Some trade-off$ though don't serve ME as much as it serves the manufacturer, or more precisely people who put parts together and decided of its features. And since i spent a lot of my spare-time on it lets now appreciate how the trade-offs translate actually, still trying to remain coherent with the present tiltle!

These are the few OSes able to install from a YUMi-exFAT (Ventoy-based) storage unit, some unique convenience i ain't no need to trade as there's a user option to disable Secure Boot selectively - lucky me... Also, please keep in mind many OSes couldn't reboot by themselves, only after the next install retrieved them so now they've all survived the reboot procedure, finally:

  • Manjaro - It's got a most unstable installment of VLC, garanteed to stall hard until i kill it properly! But i liked everything else so much! It was a charming user experience that changed me from what's next.
  • LMDE - It pleased me at 1st, then it failed the test of time, real quick - or perhaps i killed it too, me an Egzo-maniac! Poor thing, it 's so cute while i initially felt great hopes we'd get better acquainted, ultimately...
  • XUbuntu - Ah yes, Errror message boxes keep anoying me, by chance that ain't no bomb or it render me nervous. Anyway i used to like it, when i didn't have to pet it, yano.
  • Fedora Xfce - Once again my heart was broken, or more precisely both VLC and DnfDragora kept crashing. A no-go as far as i'm concerned. This is one of those occurances when i noticed rtw_8821ce timed out somehow; "ioctl" errors seemed serious enough, i may have got my HardInfo report but i wouldn't insist if not!
  • Fedora Cinnamon - How can two sisters behave so differently!! Besides Win11 that's possibly my 2nd best and only practical option, e.g. one i can recommend, if you need VLC, BT sound and HardInfo (v2 preferably).
  • Sparky - Almost won my heart too, at least it made me curious about the « Arch » Linux branch, or is my memory failing? ... Anyway, in comparison my former preference for SlackWare vanished long long ago when i tried its v15 release, even most of the « live » ones i'm afraid. Hermetic CLi-obcessed user-interface don't help make friends.
  • MX - My best man until i destroyed the CherryTrail - R.I.P.! No chance i'll forget it was bricked because of a fatal BiOS change, so maybe Dell's SMBiOS was the one trade-off to put on the balance plate where other advantages go. Just gimme time so i can list them, euh...

But no, Dell may have tricked me despite decent efforts to decide wisely. Their product IS doing what's it's been built to do i shall admit.

The adage « Fix once, break many » never been so concrete nonetheless. I'm reasoning the passage of time will allow Linux to pick up the additional momentum it requires to render Dell 100 % supportive of Linux. One could point out my requirement of a bootable YUMi-exFAT drive is actually unfair, so be it; yet lets consider that's helping to prove my detrimental slogan wrong (on the long-term...); to ignore such contribution would be moon-walking backward in any case. In short i won't pretend Ubuntu + Rufus or else are so bad not to find a place on my short list above! Just that i got no spare-time for the rest after delaying expected activities for 2 weeks.

Good day, have fun!! :cool:

Well, I can only hope that what you disabled you'll be able to re-enable if need be in the BIOS.

It's good to hear that this machine does what it's suppose to do.
The trickery that you mentioned:

These are those got ya's that are IMO unseen at times.

Sometimes even the wisest decision's don't produce the greatest benefits.
At least in the functionality and performance department with laptops.

Overall from your experience and the time you have spent with this laptop (at least with the distro's you tried) it's not something you would recommend for folks to purchase. Is that correct?

I'm not assuming, just asking:-:)
 
...can only hope that what you disabled you'll be able to re-enable if need be in the BIOS.

Disabling the external HDMi display during boot time was NOT my idea; yet it may have been this way before i noticed, from the begining. Anyway it sort of worries me still not having a BiOS recovery flash drive, being too lazy (after getting drained...), just assuming Dell's safeguards can catch up the day i need it...

It's good to hear that this machine does what it's suppose to do.

It sure does, so far. Dell ruined a 1st impression nonetheless! What's troubling me most i guess was to find ZERO mentions of the string "B92LTW3" which i NOW know to be a « Sevice Tag S/N », since i found it in print on this NetBook's back... Checking my notes it seems many "Part Numbers" kept flying all over the place, hence the perpetual confusion - an unsolvable clue finally cleared with help from the machine itslef, via HardInfo: it's a Dell SKU #0B92.

:oops:

The day before my purchase i downloaded document 'inspiron-3520-ss-fr.pdf' in some futile attempt to deceipher their configuration matrix, in vain as it obviously didn't allow ne to predict the outcome correctly. Of course there's lawyer fine-prints in it, paving the way to such model substitutions, so actually the term « unseen » sounds quite like an understatement here!!

Sometimes even the wisest decision's don't produce the greatest benefits.

I mean if one feels a need to hire a lawyer mandated to hire a NASA engineer, etc., m'well that maybe the hint it's going to prove wrong to overlook. They win, i loose: lesson learned, just too late as there can be only 1 first time.

...it's not something you would recommend for folks to purchase. Is that correct?

Naturally it depends on the individual, my own fault was to be quick to gamble with a loaded dice. Other opportunities equally qualifiable as an « End-of-Life » product line offered me SATA3 like transfer performance too while i assumed M.2 juxtaposed with NVMe/PCIe was good news (...), especially putting a convenient amovible format in the balance that my selection option doesn't offer. Etc., etc.

Perhaps it's possible to get a great Linux experience, somewhere somehow. YMMV!

I wish the best of luck to all players... :p

Understood:-
A intriguing and educational thread.-:)

Thanks for the details and all of the feedback.
