It only takes a couple of seconds to compile Python within grub though which more than offsets the 45 second boot time reduced to 15 seconds for caching hard drive to msata SSD though.
Too bad Enhance IO (based on facebook) kind of died without support in github it was a great utility.
@NathanOsman Question for you. Does the X11 window system require more overhead than Microsoft's DWM? Because even with Intel graphics, I have never seen Ubuntu's UI operate as smoothly as Windows 7. Also, does X11 do multiple buffering? Because I know that DWM does triple buffering when Aero is enabled...
Or is it just that the GPU drivers are absolute garbage?
@SergiyKolodyazhnyy Well you know I said I don't use Python, but when you boot with grub and want to use Python you have to compile the script. So I kind of lied.
@AndroidDev It's a combination of things. The drivers aren't as good as their Windows counterparts. But probably the biggest issue is the way X11 and DRM work (or don't work) together.
Remember that X11 is a client/server network protocol from the 80s.
Actual question is this. I've 9 states for the traffic control , one of which is is red for all directions. From yellow arrow or yellow light in any direction, controller goes into all red state. Now, from that state, i need to decide how to keep track of whether or not I've yielded one direction, main street arrow or cross street arrow ?
In other words, i need to somehow logically keep track of the sequence of events
Every time you said state I thought Province in Canada which made me remember Quebec where pedestrian crossings where 6 ways all at once and all vehicles get red light at that time.
Well, that's an option,too. I can let it cycle from letting cross street go, to cross street arrow , to main arrow, and then back to main street green. But ideally, I'd like to switch to arrow only if there's a car waiting for arrow
But I can't just do something like if( state == all_red ) next state = arrow_go;
I need to be able to go from all-red, to arrow, back to all-red, and then even if there's a car waiting for arrow again go back to main green
Cycling over a sequence can be done, but it's . . . sort of a cheap way out. I wanna make something actually working like the real thing

@Zanna I am stupid, I didn't look well, still have to edit to make the answer fit for Nemo (it turns out Nemo is his file manager). No action needed yet. I shouldn't handle these things when really tired :(, I make stupid mistakes then.
It always says it wants to install some important updates and it claims that the "system" can't do that without me rebooting... that's a bug that never got fixed.
Please help me to find out the list of command required to process a operation in GUI ?
For example,
If I change the wallpaper from GUI what is the command behind this .

@Zanna I am not sure, but I believe there were some questions on the subject. Might have been on U&L though, I don't remember. The issue is what you define as most recent. On Linux, there is no way to get the creation date.
@Zanna Sure it's been asked but using find should be fine if you do it right. If not, write a shell loop using stat to get the file's modification date.
@Nux found a great solution for this which you should all upvote. I decided to write a little function that can be used to run everything directly. Just add this to your
~/.bashrc.

can someone else hammer? I couldn't because I edited the tags, and steeldriver couldn't because it didn't have the tag before I edited it, but it's totally a dupe
I want to write a command that gives me the newest file in a directory recursively. But that's not my only limitation. The files has to be an mp3 or a jpg file. (case insensitive prefered)
I only need the creating date of that newest file. If possible I want it formatted like this:

@Benny I am afraid it isn't. You completely misunderstood the question (which is reasonable since the question is very unclear). The OP isn't asking about apt's cache.
I advised @DavidS to come chat here with us because he was expressing frustration with systemd in the Vegetarianism chat room. I said people were more likely to sympathise in here

I'm curious about GNOME becoming Ubunut's default DE in that I hope that Canonical (and unaffiliated developers with a focus on Ubuntu) may give GNOME some love and either take over the maintenance of in-tree features that are scheduled to be axed by GNOME developers or develop/maintain some extensions that bring new or restore axed features to GNOME.
The latter sounds more in line with the philosophy of GNOME (throw out everything that we don't deem important) and Canonical (why should we submit patches to upstream when we can just maintain our own patch set or fork).
@DavidFoerster What I saw so far is that it would be a good idea to include the dash-to-dock extension by default to make the transition for not so experienced users more easy ... on the other hand I would appreciate the pure vanilla GNOME version that comes with fedora ... GNOME experience is very good here. :)
@cl-netbox I'm also curious if Mir is going to be Canonical's next Unity: dissatisfaction with the currently available solution (X11/GNOME2), but instead of support for the dedicated successor (Wayland/GNOME3) they roll their own (Mir/Unity).

@Anwar Better today ... I wrote a good and useful answer yesterday ... the user was exremely happy ... only disappointing thing : not many upvotes ... :)
@Anwar No, I think it is because it is a bit too complicated to read and understand ... it was that one -> askubuntu.com/questions/905087/… - the thing I was talking with Rinzy about. :)
