The following question has the same exact behaviour as me. They suspected bad USB drives, but that is not my case as I have been trying 5 different ones I have laying around. They work on other laptops I own (older models).

• Live USB hangs after selecting GRUB menu entry -- new PC
• https://www.reddit.com/r/archlinux/comments/tixdun/cant_boot_live_usb_on_new_laptop/ (someone very recently had the same issue as me, on the same model)

What are my PC specs?

I have two laptops, same behaviour:

• Asus Flow X13 (2021). Nvidia 3050, AMD Ryzen 9 5900HS, 16 gb ram
• Asus Flow X13 (2021), Nvidia 3050Ti, AMD ryzen 9 5900HS, 32 gb ram

What happens?

1. I plug in my newly created Ubuntu USB drive to my machine
2. I boot from the USB drive, I select "Ubuntu" from the grub menu
3. I get a blank screen. After a few seconds, the machine just reboots. Removing grub entries like "quiet", shows me text saying: Booting command list, but no more output.

What have I tried?

• I have tried to modify the grub boot entry on the live USB by pressing e and then add items like nomodeset, modprobe.blacklist="nouveau", nouveau.modeset=0 - that in hope for it being GPU related. No luck.
• I have tried both of my laptops, with same behaviour
• I have downgraded my BIOS from v409 to V408. No luck.
• Made 190% sure that Secure boot is off.
• Tried 5 different USB drives
• Been using different tools to flash the Ubuntu images; Rufus, Balena Etcher, YUMI, UUI
• Been trying 20.04, 21.04 and 21.10 with same results.
• Linux mint 20.3 boots without issues from Live USB.

My question

I am in a situation where I am lost on where to go next. I have tried to get all the information I possibly can. What is Ubuntu doing differently from Linux mint? How can I proceed to identify the issue?

I work at an IT company, started here not so long ago. Many of us are using linux, and I have discovered a problem or security issue with Ubuntu. As it is now, locking the screen is of no use in case there would be a user-enabled process running a certain command: gnome-screensaver-command --lock or loginctl unlock-session

None of the commands require a password to reactivate my desktop, and I honestly consider this to be pretty unsafe (or at least removing the safety around having a lock screen after all). I had expected it to ask for password when trying to re-enter the desktop environment.

I noticed this behavior upon developing my own bluetooth-lock functionality, so if someone moves away from the pc the screen will lock. But I had not expected it to be so easy to unlock it.

Are there any previous discussions around this? I find it very weird it is supposed to be this way.

Background

I am using bluetooth audio a lot at work to play music to my wireless headphones. It could be spotify or other tools such as youtube, local video playback, etc. As headphones goes as a much used peripheral for my part, I want it working in a certain way.

Question

Is it possible to adjust the Ubuntu volume slider by using the headphone volume controls? It varies from distro and operating system and phones, that some connected devices actually adjusts the "system" volume instead of the built-in volume in the headphones.

When i tap volume up, i want the ubuntu volume to increase and not the volume available in my headset. Because if i have 20% sound on ubuntu, my headphones can only vary between 20% and 0% - I can't increase it.

Are there any known workarounds for my issue? I tried looking it up but my searches gave no results.

System info

Ubuntu 18.04, Lenovo Thinkpad X1 Carbon 6th Gen.

I've been trying to find people with similar issues as me, and no luck. I just installed Ubuntu 18.04 on my newly bought Microsoft Surface Book 2 - and it's a very handy and portable machine. I know it's not "intended" to use linux on such devices, but I am a linux fan so why not.

As of a fresh install, I could notice my computer got really hot - and it stayed hot. It turns one of my CPU threads are maxed out all the time. Why is ubuntu doing this? I can't find any processes using any CPU at all when idling.

"htop" shows no significant usage on any of the processes there either, and sensor values reads around 80-98 degrees on the package constantly. So I swithced over to Windows for now.

Some information about my issue

I just installed 17.10 on my laptop. the installation process went fine, and additionally I was running a live USB in order to test if everything functioned. One thing I noted myself, was that whilst moving the mouse, the mouse felt like taking steps in every direction - resulting in a laggy movement.

If you have a grid, it feels like the mouse is attaching itself to every cross in the grid, whilst moving. The effect is mostly noticeable in diagonal directions, but can also be noticed elsewhere. Doing smaller movements is challenging, as the mouse bumps.

I tried changing the available settings in the stock settings menu on the system, without any apparent luck. I also tried searching for similar issues, but I am not sure if they describe my problem exactly. For instance, lets have a look at: Jerky mouse movements

I've tried changing a few values here, but had no luck as of yet getting rid of the "grid movement" of my track-pad.

Connecting an external mouse to the laptop seem to come around the issue, but I am still not satisfied with the performance of the track-pad. Moving the pointr with my track-pad is not going well.

If there is any other information that would be handy to have, just let me know and I'll provide it. It's an annoying issue as I can't use my external mouse at all times.

I'm trying to make my ubuntu clean and tidy, and there is a few launchers on the unity-bar i would love to get rid of. For example, I love the feature with the desktop-switcher. But, I am only using my keyboard for that function, and the icon on the unity-bar is annoying me (since i am never using it). I can't just put it in the trash, it's stuck on the bar. I've tried to go to the appearance settings, and ticked away the checkbox for the desktop-switcher. The thing is, it disables the whole feature, and that's annoying.

Another example; Mounted hard-drives and USB-pens? Why do they have to appear on the bar as well as other things? And the "Show Desktop" Icon?

Those icons are taking too much space on the bar, and i want them gone,

If you have any smart ideas on how i could customize Unity for my purposes, I would love to hear from you.

Thanks!

Fuzzy icons when odd number-sized in launcher bar - unity

Description of the problem

When entering the appearance settings in the system tools, you can change the unity icon-size with a slider. When making this slider go on odd numbers (e.g. 41, 43, 39), go can note a notable difference in the quality of the icons. This is because the launcher is saving resources on the quality when having smaller icons on the unity-bar, but why is unity doing this on all the odd-numbered sizes?

Question

How can i make the icons remain big-resolouted when making odd-numbered icon-size? I have attached 2 screenshots to describe my problem where i used 40 and 39 as setting on the slider. and

You might want to zoom in on the pictures to watch the difference. And i am probably considering this as a bug; in 13.04.

That is what i got when reinstalling my software center. I tried to reinstall it after there was a problem doing installations via it. Now, this came, and well, what is the next step to do in order to get it work again? Its boring to always have to use the terminal for installations.

This is the terminal output when attempting to install Audacity in my software center: http://pastebin.com/vKc2EXG0

EDIT: I opened a bug report with this issue.

The /usr/share/app-install/desktop/sonic-visualiser:x-sonicvisualiser.desktop: Here. , existed. The other files didnt exist/was empty

I've read this page: http://www.ubuntugeek.com/how-to-use-ssh-via-http-proxy-using-corkscrew-in-ubuntu.html And it tells me to open up the SSH config file, which was in 2008, located in "~/.ssh/config" well, it was not a recognized path at all, and the file didn't exist. So, where can i find this file now in 2013 ? I am sure there are made changes, and if anyone know, i would appreciate that

Thanks! Best regards

How to get my computer use a proxy ON my computer, which connects to the school proxy ?

The reason I ask this, is because I need all programs on my computer, absolutely the whole system to go through the network, without having to use proxy authentication?

Then I was thinking of a possibility to use a local proxy without authentication, to connect to the school proxy (with all authentication details), and then be able to make the system go through it? Is that possible?

I've heard some stories about using IP-tables to make a transparent proxy, but I have no idea how to do that, as i am pretty new at all this.

So, details, explanations and suggestions about this are very welcome!

If you need more details, I'll provide them!
