So I locked my windows work computer before the lunch break, came back to Ubuntu's login screen... (I dual boot)

So windows just randomly restarted? Rip if I forgot to save something...

I am using Dell Insipiron 7567.
I have dual booted my rig with Ubuntu 18.04 and Windows 10.

Right from the start itself I couldn't get to the screen of trying or installing with default settings. I had to use 'nomodeset' with 'quiet splash'.

Even after installing I had problems. After some hours of searching I found out that installing Nvidia 390 driver would remove the bug. It did. But my rig heats like shit. And throttles very much. Where as I am not using anything other than
1.chrome
2.vscode
3.terminal

Which i think is very normal?
And looor of battery drain.

I used to get around 3-5 hrs of battery life in Ubuntu Gnome 16.04 but now its like max 2 hrs.
Which is bad I guess.

I switched back to "X.Org X server" driver with "nomodeset" (without nomoseset it will load upto login page. Once i hit enter it gets stuck) it boots up but can't change the level of brighness or can't do anything related to display setting. Temperature has reduced but sacrificing on display settings.

Is there any way to remove this bug?

And additional infos

Graphics in about shows something like "llvmpipe (LMVM 6.0, 256bits)"

Guys do respond please?

Newbie Linux User - Story about not working GUI

I am a proud Opensuse user for about a year, still struggling with some basic stuff, terminal, etc.
The story begins when a few days ago I try to login to the system. To my trusty Gnome. I get stuck on login loop;
successful login - > black screen for a second - > back to login screen.

Zero feedback, not a single error message

Stress level increases taking in count that I am at a climax at my university with tons of projects on my computer.

I assemble the Team A:
Me, Google, Stackoverflow, and for desperate times Russian Stackoverflow

Over 4 hours, found out that my user is affected by this, tried restoring default Gnome configuration, went through bunch of logs only to find out that every user gets the same errors, still only my not working. Even KDE denied to cooperate with the same result.

So what went wrong you may be thinking.
One line in file replaced by miniconda, that changed the PATH.

Linux is the best detective game that I've ever played.
Is it something that I should get used to?

I am currently running a heavily modded version of Ubuntu 18.04. I remove gnome applications, installed xfce with sddm for my login manager, plus removed a bunch of their pre-installed applications. I mostly use AppImages and snaps for installations with occasionally using apt for packages I am too lazy to build or are not in snap form.

I have been contemplating switching to Arch/Antegros/Manjaro. Mostly because I am crazy and heard that I could get a performance boost and I like being more in control of my own software.

My question is this, does it make sense for me to switch distros? Also, I'd like to have a close to the metal Arch install, but last time I did that I got annoyed with configuring too much from the bare bone, took me like close to an hour of setup, it was not hard, just really tedious.... Is Antegros/Manjaro have options to be really close to the bare-metal? Is there maybe a really good install script that I can just tweak some basic settings for?

Can I say Ubuntu installation has really gone messy lately(at least the last time when I installed back in 2009). Especially the part of disk partition and selection. You get only three options - Install alongside Windows(without additional customisation), Install on the whole disk, and then Custom.

Most times these days people will select Custom and configure the partitions. And then the crucial part is selection of Boot Loader. But it's not given much focus which is empirical because otherwise even if your installation is successful, without the correct Bootloader config, you will continue to boot into Windows and then debugging and fixing gets really tricky. Especially for somebody who wants to try it out.

And then you will be cursing yourself to have bought a laptop with Nvidia graphics card because the drivers are proprietary and sometimes they have you stuck in Blank Screens prior to login. Ubuntu is not at fault here, but then it makes the life of people trying out things so much more difficult that will force people to just give it up.

I had moved to CentOS(because of Gnome) back in 2015 after really squeezing everything out of Ubuntu 9.04 on my Intel Core 2 Quad. And today, I installed Ubuntu 20.04 after almost 11+ years and it was really not a good experience.
