i'm trying to set a specific resolution for kms, at boot time.
by default kms choose the highest resolution available (2500x1600) which is a bit hard to read.
i'd like to set 1440x900 instead.
i tried two things via grub, the first one:

@dessert why? For me, if a question is answered by the answers on another question, that is a perfect example of a dupe. Think about it. The reason we close dupes is to avoid duplicating content. So if we need to post the same answers on the new question, just because the question is slightly different even though the answers are the same, then we gain nothing by not closing and we are forced to duplicate content.
These two seem like perfect examples, actually. The question of "why does this machine allow >4 primary partitions" is indeed answered by the answers to "what are the differences between GPT and MBR".
But consider, for example, a question that asks "How can I bulk rename files on 16.04". Wouldn't that be a dupe of "How can I bulk rename files on 18.04"?
@Zanna Sure, if they can truly be unique. I don't really see this here though. Any answer to "why does this machine allow more than 4 primary partitions" wouldn't really add anything new to "what is the difference between GPT and MBR" since that will explain that GPT allows more primary partitions.
@terdon I see it like this... if two questions are different, I mean they actually ask different things, like this case here, it might be that valid answers to one already exists in answer to the other, but those answers are a subset of all the possible answers to both of these questions.
If there is no way for an answer to be posted to one question that would not also answer the other question, then it can be closed, because whoever wants to answer it can post their answer to the target. But if it is possible to imagine (and I think I should push my imagination a bit, because I'm just one person) someone wanting to post a good answer to either question that they couldn't post to the other, then neither should be closed.
@Zanna For me it boils down to this: if there is already a more generalized version of a question, whose answers cover the specifics of the new one, then they should be closed as dupes. There is no value in the specific when we already have a general one.
While using nohup to put a command to run in background some of content appear in terminal.
cp: error reading ‘/mnt/tt/file.txt’: Input/output error
cp: failed to extend ‘/mnt/tt/file.txt’: Input/output error
I want to save that content to a file.
I answered that (and it's my highest voted answer on AU) but @ByteCommander (before his recent modship) pointed out that it's a dupe of the more general "How do I save terminal output to a file?", so I closed it.
The answers of the dupe already covered redirecting stderr so nothing new was being added.
@terdon oh I really dislike specific questions being closed against general ones unless the general one really exhaustively answers everything about the specific one
I will often leave a comment to help the OP adapt the general to their specific case, but I don't see much point in lots of specific questions when a general one exists. But yeah, this is one of the classic SE arguments with people and good arguments on both sides.
And that, in a nutshell, is one of the worst issues we have here on AU. People trying to get absolute rules and apply them everywhere without consider what the objective of a rule was in the first place.
not if the software used in 16.04 got replaced by something else. The 1st q should not have had 16.04 in the title though and the answer should be for the current release and could be expanded to include the new current release @terdon
@terdon, re. "And that, in a nutshell, is one of the worst issues we have here on AU. People trying to get absolute rules and apply them everywhere without consider what the objective of a rule was in the first place." I get what you're saying but then "participating in moderation" gets quite complicated.
@Rinzwind since 17.04 I think, it was necessary to install the Perl rename package which was previously installed by default. So there is some difference between these two questions. It's just not the kind of difference that makes it productive to have them be separate
and when I say productive, I mean creates answers, creates useful stuff
@terdon, one is written, the other isn't. I like clear rules that don't need a lot of thinking. So far, flagging spam seems to be a pretty safe activity ;
that is what a good unique question has the power to do
even if it is to some extent a subset of another question
there are people who say biology reduces to chemistry which reduces to physics which reduces to maths, but just try explaining any concept in biology with maths...
at some level of difference there becomes something worth saying hahaha
so I won't say oh this is a wrong closure. But if someone expresses an interest in posting an answer, then I'll be pushing for reopen right away, because it's more answers that I want
was someone looking for an absolute rule here?
@ByteCommander it is funny that purity comes with prestige, because nothing is more interesting to study than a total mess like human society XD
But I wasn't being serious, of course. Just joking about the fact that there is very little interesting work left to be done in chemistry. What's left is in the realms of biochemistry or physical chemistry. Most (all?) of the Big Questions® in chemistry have been answered.
the thing is though, chemistry is really useful for impressing teenagers. Like, did you know if you boil wax and drop it in water you get a MASSIVE fireball?
There's a lot of work to be done on specific problems, of course, and it is very, very far from simple or easy. But the big issues have actually been addressed.
haha I did this subject knowledge enhancement course in physics
all the teachers were awesome
but my favourite was the crabby, strict guy everyone else didn't like. He set the best problems and he never fudged the details or wasted words
when we were doing gas laws he admitted to being a chemist
most of the chemistry teachers I've met as a teacher seem to be mainly interested in setting stuff on fire or blowing it up, but the chemistry teachers I've been taught by were all details people who taught me something I won't forget
like my year 11 chemistry teacher wouldn't let us use the word "amount" "unless you actually want to be vague"
so since then I've had a habit of thinking about which word will most precisely express what I want to convey haha
he would say if this tennis ball here were the nucleus of an atom, the nearest electron would be out in the tennis courts (on the other side of the school). That kind of vivid example I am still using to explain stuff to kids even now
@DKBose That is true for all rules & regulations... And even tough the mods here try to do their best, AU is part of the SE network of sites and the money company ulimately decides what the direction should be.
@DKBose yes, there has to be some means to make decisions, I think... Fortunately there is always the skip button <3... The more time you spend with the site, the finer grained you can make your own internal rules or heuristics. I end up changing my mind over time which is great fun haha
@terdon In a few years, we'll have an open database of genes and they will be used as "parts" in a "material Database" to build new and exciting life-forms from scratch.
(We're modifying existing ones already using this approach)
I'm looking at rotating the log files of NGINX on Ubuntu Server. As far as I can see (1) there's already a cronjob for logrotate to run daily and (2) there's already a default /etc/logrotate.d/nginx. From the logrotate status file, I see that it's correctly run on a daily basis.
However, my NGIN...
I think I have downvoted because someone went out of their way to make something obscure. Maybe not. If the answer is more confusing than the question, that merits a downvote.
