Ubuntu laptop in USB flash drive or SD card

I want to install a portable Ubuntu on a USB flash drive or on an SD card. I don't know which one is better. I will use it a lot. I think in any case it is better for me to keep the unit / card plugged in. In this way, every time I need to use Ubuntu, I will not have to insert it and thus avoid deterioration caused by continuous insertions / expulsions. On the other hand, is it still a good idea to keep the drive / card connected all the time, even if I use Windows, not Ubuntu? I mean, is keeping it inserted also harmful to him? If so, which one is less harmful: keep it inserted or eject it after use?

I also need your help regarding the speed of the USB flash drive and the SD card. Which one is recommended for my purposes?

Thanks in advance.

nvidia: my laptop with 19.10 cannot be resumed after every third suspension

A week ago, I updated Ubuntu on my ASUS X556U laptop from 18.04 to 19.10. (I did it in two steps: 18.04 to 19.04 and immediately 19.04 to 19.10)
After this update, I had a strange problem. My laptop cannot resume suspension every third suspension / resume cycle. He is dead after the third suspension. There is no disk activity. Two suspension / resume cycles are good, the third fails. I am sure the problem is in Nouveau and on my NVIDIA GeForce 940MX card. I receive the following error messages all the time:

**nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6013d4 ( IBUS )**

Before version 18.04, I could not turn off my laptop if I suspended and resumed it before, because NVIDIA did not stop. But, after the update to 18.04, I had no visible problems with Nouveau.
I don't see anything suspicious in the records, although I don't have much experience in analyzing records.

Is there any idea what is going on?
Is there anything I can do?

networks: the laptop does not have a wi-fi button, it cannot turn on the integrated adapter

My laptop does not have a button or shortcut on the keyboard to turn on the Wi-Fi adapter. In Windows, there is an option I click on that, and then I can search for Wi-Fi networks. I can't do that, and I think that's why every time I access the Wi-Fi configuration section, the message "Wi-Fi adapter not found" always appears. I (semi? -) updated all the drivers and I used an external USB adapter and it worked. If that's the case (I can't turn on that adapter to look for connections), how or what should I do to be able to search for Wi-Fi networks? I have been working through the power line so far and it is not a practical solution.

Any thoughts appreciated!

Drivers – Ubuntu 18.03 on a MacBook 5, 1 (unibody from the end of 2008). Low performance. Is it expected on an 11-year-old laptop?

Note: I am more interested in the theory behind any answer. I am interested in knowing if such a perceived poor performance is expected. Can it be due to old hardware, etc.? This is a secondary laptop and it is not critical to make it work. I'm just curious about the reasons why it could be the following.

I recently made a new installation (Ubuntu 18.03 on MacBook 5.1). I was happy with Firefox until I discovered that Netflix could not run on it (Firefox is not compatible?).

Netflix ran on Chrome but the video froze (the sound continued). It would eventually catch up. Once he did that, he was able to run the video correctly. However, by not doing anything else, I realized that the average load was around 2.20 2.20 2.20. Something similar happened while using YouTube.

Potentially my real problem is with Chrome?

Note: The use of RAM (4 GB available) was fine, using less than 2 GB.

The other thing that I thought might be a problem is that I am running the open source nouveau drivers. Should I be running the proprietary drivers?

Everything is standard (since it comes with a new installation), nothing else runs in the background.

Is there anything obvious to alternate with a Linux installation on a MacBook? Is the CPU throttling due to poor heat circulation? Or maybe it has something to do with low battery performance?

My guess is that 8 GB of RAM and an SSD will not affect the average load (is that true?).

boot: the laptop screen remains dark with the appropriate controller and resolution

I have an XMG Clevo P150HM laptop with an ATI Radeon HD 6970 M graphics card and a Full HD display. When I boot it, the BIOS screen is there, then there is the Windows logo and then the round thing turns, but when there should be the login screen, the screen goes dark and stays that way.

Additional research revealed something fun: reinstalling Windows 10 runs without any problems. But when Windows installs updates and drivers, as soon as the ATI driver is installed, the screen goes dark and stays that way. I tried twice, the second time I installed drivers downloaded from the ATI website instead of the drivers through the Windows update mechanism. At the time the ATI drivers are installed, the problem occurs. This is a fairly new development, I have been using this laptop for quite some time and it worked fine.

Then I wanted to install Linux, but I didn't get that far: after the BIOS and the grub screen, the screen goes dark and stays that way. Apparently, after the grub screen, the boot process changes to another resolution, probably the native screen resolution, which seems to trigger the problem. The Linux distributions I've tried are Ubuntu 18.04 and CentOS 8.1, booted from a USB stick.

Finally, I connected the laptop through HDMI to my TV. During the Windows boot process there was a text & # 39; No signal & # 39; on the TV But at the time when the laptop screen went dark, there was a reaction on the TV: the text & # 39; No signal & # 39; disappeared and there was an input indicator & # 39; HDMI 1920×1080 & # 39 ;. Other than that, the TV screen remained dark as well. Once I disconnected the HDMI cable from the laptop, the text reappeared & # 39; No signal & # 39 ;.

I guess there is something physically broken with the graphics card. My question is, what exactly could that be? Has anyone experienced something similar and researched more? Is there any reasonable chance that I can fix this?

Installation: automatic installation of an APK file after saving it to the SD card of the laptop

Is there any way to install an APK file on Android that was placed on the SD card from the laptop?

For example: I accessed the storage of my phone on my laptop through a cable connector and saved the APK. When I disconnected the cable connector, I want the apk to install it automatically on my Android phone. It's possible?

network – How can I create an isolated and anonymous operating system inside my employer's laptop?

My employer monitors every website I visit on the company's laptop, so I need to create an isolated operating system and connect to an invisible VPN so that the IT department doesn't know what websites I visit and shouldn't even know that I am connected to a VPN and use isolated OS.

My solution would be:

  • Qubes and earn 10 inside him

  • A Stealth VPN service like Nordvpn (that the network won't know that I'm connected to vpn)

  • Maybe a usb to save and connect at any time

  • My mobile phone 4g internet or company wifi (?)

Note: It is not necessary to have complete anonymous systems such as whonix, tails, etc. I just need to browse the web for my personal needs and save my personal documents. Therefore, the Windows operating system is required.

What solution would be fine?

Windows 10: the fixed startup entry & # 39; Hard disk & # 39; is missing in UEFI – HP Laptop – After moving the HDD to the SSD

While my HP 245 Windows 10 laptop works fine, this question is to better understand how UEFI manages boot entries.

In the UEFI firmware, apart from the OS or user-created startup entries for UEFI mode, there are some fixed generic startup entries such as, start from

  • Internal hard-drive
  • USB disk
  • CD drive
  • Network Card, etc.

I had the same entries on my HP laptop. I recently removed the HDD and replaced it with an SSD and reinstalled Windows 10. Now Windows 10 works fine but the fixed input for the Internal Hard Disk is completely missing in the boot order. Since SSD is connected to the SATA port, UEFI should have retained the entry, I suppose.

Is this normal or an error in UEFI? My UEFI is updated to the latest version and HP has not released any other version.

Look at the screenshot. Between the operating system and the USB elements there used to be an "internal hard drive" item in the boot order.

networks: the laptop cannot start iwlwifi

My new installation of Ubuntu 18.04 cannot detect the Wi-Fi adapter of my laptop, Intel AC 9560. This seems to be the result of iwlwifi not initializing properly. As some other publications here suggest, I installed the iwlwifi with backup to update the firmware from version 43 to 46. Iwlwifi still cannot be initialized after the update. What else can I try?
