I'm trying to dual boot Ubuntu 16.04 with Win10 on my MSI and do understand that they're fairly notorious for making linux installs a hassle. I've made pretty minimal progress with the install and get stuck and the load screen whenever I try to install from an ISO on a usb. Ive turned off secure boot, fast boot, and Intel speed technology in the BIOS. I can only boot to the USB when its in Legacy mode, but I feel like it needs to be in UEFI mode for it to boot properly to Ubuntu. I used RUFUS for the USB installer which is compatible with UEFI. Am I no longer looking at BIOS issues and should be looking elsewhere? Any help is appreciated.  EDIT 1: Ive now got a working Ubuntu partition on the HDD however now when I boot the computer back up I can't access grub no matter the priority I set in the BIOS. It just goes straight to windows...  EDIT 2: Ive successfully got my computer to boot to grub every time giving me the option of windows or ubuntu, now there are issues with ubuntu allowing me to log on and use the os. Ive done editing with nomodeset after hitting E with Ubuntu highlighted, but that change doesn't save and if I dont do it every time I cant boot to ubuntu...  EDIT 3: Now I run into a new boot issue. I had it working for a while, got some drivers and Gnome set up, then when I went to restart to check it was solid and sturdy on boot, it hung at the boot screen. Typical purple/black hang error usually solved by nomodeset or nvidia/nouveau.modeset=0, however these solutions didn't work for me. I either experienced the same hang or was left with a text-based boot screen that yet again got stuck  EDIT 4: Last update before I let this question sit. I reinstalled Ubuntu, had to do nomodeset in the try ubuntu option and then install it back into the reformatted partition. Got into the os, it was scaled pretty large so I downloaded the nvidia driver. Restarted to apply changed and wasnt able to boot so went back and did nomodeset again. Got access into OS but the nvidia driver was gone. Redownloaded it with some other drivers and Gnome. Went to log out to change to gnome and every time Id log in the Id get a notification saying Ubunutu has encountered an error followed by a short pause and then I would get kicked from my account and put back to the log in screen. I'm now right back to where I was. Ive narrowed it down to graphic drivers and possibly gnome? I will wait to see if there are other options.  GRAPHICS CARD: Nvidia Geforce 970M CPU: Intel i7 6700 HQ
I have a computer with a video card that has no Linux support.  I discovered this issue while trying to use a persistent usb to boot from.   I found that I can boot like that if I change options and edit so as to add nomodeset there (see ).  Also, editing the syslinux.cfg file from my live persistent USB and adding nomodeset in a line there made this setting automatic for booting from the persistent USB.  Can I make a similar edit for proper install from the same live USB?  Is it possible to edit something on the live USB in order to install the SO from it,  -- that is: having automatically the nomodeset setting already there when the installation starts?  My problem is that in order to install I think I already have to have added nomodeset or I'll see nothing on my display. I need a way to be sure that nomodeset it's permanent from the start.
Why do you write "occurred" but "listened"? The past tense of to occur is occurred (not occured), but the past tense of to listen is listened (not listenned).  Why? What is the general rule that is applied to make the past tense of a verb? UNetbootin is stuck in an "Automatic boot in 10 seconds" countdown loop I made a bootable Windows 7 USB using UNetbootin, and when I try to boot from the bootable USB and select the Default boot menu entry, it gets stuck at the UNetbootin boot menu and it keeps repeating an Automatic boot in 10 seconds... message in an endless countdown loop. Selecting Press [Tab] to edit options and editing the options has no effect. When I go back to the boot menu, it keeps repeating the same countdown loop.   I've tried redoing the UNetbootin extraction, but I still have the same issue. Can you cast a spell at a higher level, even if it doesn't have an "At higher levels" entry? How do I get a vanilla GNOME after Ubuntu 17.04? Some people (me) would prefer the straight GNOME experience as opposed to the Unity style desktop offered in Ubuntu 17.10.  How can I get the standard GNOME desktop and interface? What is the name of the horizontal division line? What is the name of the horizontal division line?

Every time I shut down the computer and turn it back on after a day, the battery level decreases by about 5%. I'm sure that the computer is shut down, not in sleep or hibernate. I removed the battery from laptop and after inserting it, the battery percentage does not change. I tried updating the BIOS, disabling wake on LAN in BIOS options, and calibrating the battery several times.  Is this drain normal? If not, is it a hardware failure or can I fix it with software? I've been using Ubuntu for a few years now, but I just installed Version 16.04, and I've been having a lot of issues. I'm not a command line expert, but I tried to install some software last night, and it is creating issues (and also not working properly).   When I run sudo apt-get -f install, I see the following message:  Reading package lists... Done Building dependency tree        Reading state information... Done Correcting dependencies...

Currently there is a red circle with a line through it in the upper right corner that indicates there may be installed packages with unmet dependencies. Compact topological space with closed graph implies continuity Let $X,Y$ be topological spaces and $f:X \rightarrow Y$  If $Y$ is compact and $G(f)$ (graph of $f$) is closed, show that $f$ is continuous.   I consider an open set in $X$, and as $G(f)$ is closed, $(X \times Y)-G(f)$ is open. And I guess I need to do something here. Then I can get some open sets. Also, I notice that compact is something relate to "finite". I guess I can use the compactness to do finite intersection or union and get the result finally.  But what should I do in the middle or I am not even on a right track. why normalize and the definition of directional derivative I haven't found a similar question on here, though I suspect the question may be rather well-covered.   I want to find a conformal map from the vertical strip $\{z:-1&lt;Re(z)&lt;1\}$ onto the unit disc.  Under the exponential map the region is taken to the annulus with radii $e$ and $e^{-1}$, but I'm not sure how useful this will be.  Can anyone advise on what the conformal map may be?  Thanks. Diminishing returns / non-linear reputation from “great” answers Over time I realized a very annoying property of the Stack Overflow reputation system: Easy answers to popular question are rewarded with a lot more reputation points than actually great answers. In case anybody actually needs examples for this, here are two examples from :   gained me 420 rep, I invested 2 minutes writing it, and it only was a wild guess.   took me about an hour for the research and the math and gained me 40 rep.  Now I know that you are bound to get more rep for answers that are useful to more people, and I'd say that's fine. But the current situation is quite extreme: 30% of my reputation is from 5 of my 330 answers, and they are definitely far from being my best ones.  A final example that is not from my profile, but more extreme: Do you really think  is worth 40000 reputation?  My proposition to improve that situation would be to make the reputation gain from a single answer non-linear, maybe even have it capped at a certain point. I'm not sure on how that non-linear function should look exactly, and would leave good proposals for that to users with more experience than me. How to quickly send commands to nested tmux sessions? I have the following in my .tmux.conf  set -g prefix M-j bind-key j  send-prefix   I need to press (Atl+J) + (J) + bound-key to send something to the nested tmux session. I feel it is rather slow. Is there any better way? For example, I would love to be able to do (Alt+J) + (2x bound-key) to do stuff in the nested session. I constantly execute commands in the top tmux session instead of executing them in the nested one. Also, how come everybody binds prefix to C-a? I find it awfully slow and unpleasant to type this combination. Am I missing something? Call to a member function on a non-object Is there an optimal loss function for dealing with imbalanced classes? I'm aware that there are many ways of dealing with datasets where there is a strong class imbalance in the target variable: downsampling the more prevalent and less important class, over-weighting the valuable minority class, etc. Are there any loss functions that are ideally suited for these types of problems? I've heard of AUC, but AUC sounds like a means of evaluating a model once its training is complete (correct me if I'm wrong). Log loss and squared loss penalize a model's over confidence, but overconfidence and class imbalance seem unrelated. Is that true? Rendered image is just grey I am having some issues when rendering an image, my rendering screen is turning into grey even when making a full render. What am I doing wrong? In Batman #1 in the New 52, when we visit the Batcave for the first time, we see a dinosaur:     What... is up with that? It is a completely awesome cave decoration - but what else is it? Is it a non sequitur or is it a call back to an earlier storyline? I imagine it's the latter – a life-size T-rex model is an expensive piece of decor, even for Bruce Wayne.  Bonus points: are there any other relics from past storylines visible in this Batcave?  Update: here's a shot of the other panel that gives us a view of the "showroom" (including the huge dice). Need for a side book for E. Soper's Classical Theory Of Fields I am reading now E. Soper, Classical Theory Of Fields, now and sometimes it is very hard to follow the equations. So I need a side book on  to read it comfortably. Landau &amp; Lifshitz's book is not helping as its content and topics are very much different. Is a DNA molecule a single strand of polynucleotide or two of them linked together? Our molecular biology teacher told us that a double helix of DNA was composed of two DNA molecules linked together by hydrogen bonds. The thing is, until now, I always thought a DNA molecule was composed of two strands, those being polynucleotides, both of them being linked together. I can't find a link which is saying the same as my teacher, even if it seems technically correct to call a double helix a dimer of two DNA molecules.  I was curious to know what was the exact terminology. Currently using Ubuntu 18.04, and my wireless driver is not being detected.
