I've been working on a solution to this for weeks, and I'm about to say screw it and write a python app that can actually block IP addresses, because so far nothing seems to work like it's supposed to.

/etc/hosts can't block a range of IP addresses, nor can it block the URL I'm trying to block, and there doesn't seem to be a decent GUI that can manage iptables locally without insecurities like ssh (fwbuilder) that isn't unavailable (firestarter).

So I'm stuck to using gufw which in itself doesn't want to work:
The site shown is an ad cdn I'm trying to block for an app I use. (the log is empty)

I think I'm starting to understand why every search I do refers to cumbersome terminal solutions like ufw or iptables...

Is there any way to actually get gufw to work like it's supposed to??

I'm running Xubuntu 16.04.3, and after connecting another SATA drive and restarting to get it detected (PnP doesn't seem to work), after the restart, I seem to have completely lost wifi support, which may have been from an update during the 19-day uptime...

Typically when opening the network-manager indicator plugin, you would have an option to "Enable Wireless", which I'd been connected with on this machine I'm typing with for some time...
But you can see I no longer have that here:

Where it says I'm connected through ethernet is actually a slower wifi (~30Mbps) connection through my secondary machine vs what I originally had (~115Mbps) through my USB wifi adapter.

Also just for notes, the wifi adapter (Netgear AC600 piece of junk) is still connected, and reinstalling the driver ($ sudo make install, dealt with on numerous occasions) isn't working this time, so I think the problem is likely some automated update that destroyed everything.

How could I fix this??
What commands do you need to know to help me fix this??

I basically did a stupid as I was having issues with getting mailto links working in chrome...
So what I did was set google-chrome as a preferred application for handling mail, which backfired and exploded in my face...

Now I seem to be stuck with my mistake as I can't seem to undo my changes:
^ what I want is the blank box as I don't have anything installed to manage mail...
I have a chrome extension that does that for me.

As a result of a major compatibility problem on Xubuntu 16.04.3, since Ubuntu has dropped x86 support, the driver for my motherboard's GeForce 6150SE nForce 430 GPU (which I'm trying to use for my secondary monitor) fails to build.

The nouveau driver for this chip is newer than the run file I could get my hands on for it, but I had do disable it to install the driver (run file) for my GeForce GT430, which is the pci-e card I'm using for my primary monitor.

What I want to do is use nouveau for my 6150SE while using the run file for my GT43O and have both monitors operate under a single X-screen with xinerama.
(the idea is to reduce load on my GT430)

How can I do this??

Also I have no means of connecting the PC to internet or I wouldn't need to use run files to begin with.
(I can download stuff with this phone and transfer it to my PC, but that's it)

Everything I find tells me to use the PPA, which isn't possible for me atm since I don't yet have internet (and likely won't for a while) and this rooted phone can't teather or hotspot including through ADB.

So I need to download the packages/dependencies and transfer them to my PC to install them...

Where would I be able to find the packages I'm looking for??

I'm building a utility that simplifies the complexities of defining and adding/removing custom resolutions with cvt and xrandr down to at least 2 command inputs.

The idea is to enter a custom resolution and frame rate (similar to how you'd do with cvt) on a specific port if using multiple, and see if your monitor on said port can display it.
The 2nd command is a simple y or n entry if your screen isn't black.

here's where the trick comes in, and the problem I'm running into...

If you enter n on the validation prompt, the screen should be reset to the previous resolution, which also includes the current resolution upon startup.

The problem I'm facing is it doesn't seem possible to obtain the current modeline upon startup of the utility.

Does anyone know of a way to obtain the EXACT modeline for xrandr --output ##### --mode <mode> or is that not a possibility??

I'm looking for a tool that can give me a visual representation of my ext4 fragmentation. Something similar to how Defraggler, Puran Defrag, and many others (UltraDefrag being the best) display your disk... (most good UIs display the files in the block you're hovering your mouse over)

Is there anything related for Linux?

I want to watch my disk and see just how "unneeded" defragmentation really is.

I don't want to use e4defrag, because I'm not sure it can show me what exactly it's doing to my disk.

EDIT (2021): it would seem a similar, less popular, question has been asked 3 years before this question with suggested tools: https://unix.stackexchange.com/questions/30743/is-there-a-tool-to-visualize-a-filesystem-allocation-map-on-linux

I swear every tutorial I see and every software I run across can't give you an exact image of your drive, it's either gzip-compressed, or it's in another format for some specific software.

I want to open the img in HxD to manually recover my data, so the image needs to be in the EXACT byte-order of the disk.

How can I do this??

why manual recovery over recovery software?

ChkDsk did quite a number on the filesystem, so much so that any mount or recovery gives you 0KB files in 300GB of data.

the data is still there, but nothing can find it.

So I've just recently decided to try out MonoDevelop for other things after writing a review a while back about .pyproj files not being supported...

turns out, I'm unable to edit my review for it to mention it's lack of support and broken features as well as being outdated.

I wanted to rate it 2 stars as it's about as good as using Visual Studio w/o any advanced features.

but my 4-star review I made earlier has no edit or delete option, and of course I'm not allowed to submit another review...

what's going on here, and why won't it let me edit??

As the title states, I'm trying to use Windows python on linux,
which already has worked flawlessly for what I've needed to run.

however .py files open with gedit instead of python, meaning I actually have to open python directly before I can do anything.

I've read an example that told me about a desktop entry for pdf files, but of course I don't know what I'm doing and nothing's explained for noobs, so I tried rewriting it to work with python:

[Desktop Entry]
Name=Python
Exec=wine python.exe %F
Icon=python
Type=Application
Categories=Viewer StartupNotify=false
Terminal=true
MimeType=application/py

the terminal just appears then disappears

what am I doing wrong??
