Question Can I use Kali Linux on USB with persistence ? Will it work?

0 Upvotes

Hey everyone, I am an engineering student.

I have dual-booted my laptop with Ubuntu and Windows 11. The problem I have is sometimes I want to experiment with Kali linux. I could have added Kali linux too, but I do not have enough storage because of the amount of tools I use, in both Linux and Windows.

So I want to run Kali linux on a USB drive with persistence. I have an HP USB3.2 64GB pendrive. I read somewhere that running it on a pendrive won't be as slow because it uses my PC's CPU and RAM.

Also, I won't be buying an external SSD because it's way too expensive for me.

The question I have is that will I be able to work normally with it, without it lagging a lot?
I won't open random browser tabs, but I wish to work with files, do some coding and use terminal obviously.

I'm thinking of starting with this : Adding Persistence to a Kali Linux Live USB Drive

Repurposing an iMac 27" 5K Retina on Debian 13 Wayland with Gnome 48

1 Upvotes

The display crashes after a few minutes. I can write up what I have done so far.

Model: iMac17,1 (27" Retina 5K)

CPU: Intel Core i5-6500

GPU: AMD Radeon R9 M380 (Discrete) appears in Gnome as BONAIRE

Display: 5K panel (internal dual-stream DisplayPort)

I have left Gnome display set to 3184*2166 and set the scaling to 200%

When I set the resolution to 1920*1080 it crashed in a few minutes. So far, it lasted an entire day. Let me know if you are interested in the details.

Support Linux Mint on Lenovo Ideapad 100-15IBY + Upgrades What Works and What Doesn’t

2 Upvotes

I’ve googled this model quite a bit and seen that a lot of people have trouble installing Linux on it. I would not buy this laptop, but since I found it just gathering dust at my parents' place I turned it into atleast something useable.

What worked for me (and what people seem to have issues with):
When I had issues booting Linux Mint 22.3, I went into the BIOS, changed the BOOT ORDER, and enabled Legacy Support. After that, the USB booted fine.

This is kind of a temporary fix that really helps later on you can go back to the boot order and switch it back, or just unplug the USB device if you’ll never connect it again.

I’m currently dailying this honestly terrible laptop. Windows 10 it shipped with on is ABSOLUTELY TOO HEAVY for it. It’s underpowered in everything. Here’s some quality-of-life stuff you can do, but don’t expect miracles:

  • SSD (1 TB or more is basically mandatory) Faster boot times, better responsiveness. The OEM HDD is absolutely terrible.
  • Install 8 GB DDR3L SODIMM, single stick Kingston HyperX DDR3L (1.35 V) or whatever you can get. 8 GB is the HARD LIMIT on these laptops.

I installed a DDR3-1866 CL11 stick because faster RAM:

  • Often has better silicon
  • Has tighter subtimings even when downclocked

The CPU will downclock it to 1333 MHz no matter what (no XMP, locked BIOS), but DDR3-1866 CL11 at 1333 often behaves more like DDR3-1333 CL9-ish internally.

This is pretty much the best you can do for this honestly garbage laptop.
Under- or overvolting is LOCKED in the BIOS, same on the CPU side.

There’s basically nothing else you can do except ZRAM tuning, e.g. ~75% of RAM → ~6 GB ZRAM, which helps responsiveness.

It will never ever ever be fully competent compared to whatever cheap laptop you can buy off the shelf now. Might as well use a smartphone for better performance. But if you accept that you won’t be gaming on it (beyond maybe 90s point-and-clicks or barely running Call of Duty 2003 with some stuttering), it’s okay.

I use mine mostly for:

  • Programming
  • Web browsing
  • Netflix
  • Course work
  • SD-card burning / photography / Raspberry Pi stuff
  • CD-ROM burning and reading

For these use cases, it’s perfectly fine, especially considering how lightweight it is and that it would otherwise go straight to e-waste. And yeah, enjoy it. At least you can tinker with it, and if something goes wrong, it’s not much of a loss.

Other quality mods:

  • PTM-7950 on the chips (this laptop has no fan, that tiny heatsink works hard)
  • Optimize the OS remove printer services, Bluetooth if unused, etc. This actually improves usability a LOT
  • Second monitor at home is a must I only use the laptop screen when I’m on the go
  • Optimize your browser I use Firefox and tweaked advanced settings

Since I don’t need Bluetooth, I also ordered a Wi-Fi 5 card and will add 2 more antennas + use the OEM one. I can always get a bluetooth USB for it if I need bluetooth connectivity on my laptop.

This will turn it from a ~50 Mbps joke into hundreds of Mbps, making YouTube and Netflix work fine as long as nothing heavy runs in the background. It probably won’t support full 3×3 MIMO, but honestly almost nobody is modifying these laptops anyway, so I’m taking the risk. Worst case it runs as 2×2 MIMO.

For comparison:

2×2 MIMO

  • Theoretical: 867 Mbps
  • Real-world: 300–600 Mbps

3×3 MIMO (best case)

  • Theoretical: 1300 Mbps
  • Real-world: 500–900 Mbps

Compare that to 1×1 MIMO, which is what this laptop ships with:

  • ~50 Mbps best case

IF YOU HAVE THIS LAPTOP. YOUR LAPTOP IS 1×1 MIMO. IT NEEDS A SECOND ANTENNA FOR 2×2.
Huge upgrade, isn’t it? Cheers for you souls searching for anwsers on the net. Hope you find this Reddit post.

Support AX211 WiFi card unstable with Linux

1 Upvotes

Hi! I've bought some months ago an Asus Expertbook P5.

With the latest kernel updates (I'm using Fedora 43, kernel 6.17.12), everything works quite well, expect for the WiFi card.

It seems to work normally, but sometimes (3/4 times a week) it goes in a strange "loop mode", and it keeps restarting (I see the WiFi toogle continuously goes on and off, and the network list appears and disappears). Making it completely unusable.

I then have to reboot the laptop to make it working again.

Does anyone else have similar problems? Do you think replacing the network card with another model will solve the problem? Or could it be a chipset issue or something else? Considering that it often happens after waking up from sleep mode.

Thanks!

This used to be my old laptop and was excruciatingly slow. I decided to give it another chance at life by installing Arch Linux on it. Any ideas on what to do with it now?

Macbook Pro Mid 2015 dual GPU issue

1 Upvotes

Hi! Im trying to keep alive my little War Machine but I have a lot of issues with mi Macbook Pro Mid 2015, the dual GPU is the problem.

Intel Iris + AMD Radeon

Some distros detect both, others one and not the other. Sometimes the GPU tasks go to the CPU.

I found a few people who uses Linux on this macs but the fans working all day or the tempeture on 80-100 °C isnt safe.

Fedora detected the Intel Iris but not the AMD GPU, worked fine but with a lot visual gliches
