AAAARGH, in reflex, flagged this one as spam askubuntu.com/questions/964275/…. Not correctly...

@JacobVlijm I believe spam flags can be retracted if you open up the flag dialog again.

Ah, thanks! @EliahKagan

No problem! :)

I have a 500GB hdd and when I installed ubuntu originally, I partitioned it to 200GB. But now I want to use all 500GB for ubuntu.

2:11 PM

@Rinzwind I'm starring and upvoting!

WinEunuuchs2Unix

@Rinzwind terdon suggsets sudo apt lid-upgrade

answered @Rinzwind @WinEunuuchs2Unix

(I'm probably going to be downvoted into oblivion for that one)

Also voted to closed as duplicate... @Rinzwind @WinEunuuchs2Unix

WinEunuuchs2Unix

@Fabby I upvofed for follow-lid never seen that one before

@WinEunuuchs2Unix Yeah: he probably still wants that one to happen...

P.S. gsettings list-recursively org.gnome.settings-daemon.plugins | grep --ignore-case lid

Just copy-pasted all and was as surprised as you!

Meeting! AFK!

2:51 PM

Any moderator please help! I posted a wrong answer here: askubuntu.com/q/1159427/248158. My "solution" doesn't work. The window title changes if I change directories. I pinged the person who accepted my answer. I want to delete it! But I can't delete the answer since it's been accepted!

This answer has to go! askubuntu.com/a/981802/225694

@DKBose change the answer to a working method >:)

@DKBose Edit the answer to correct it

@ElderGeek damn. 2 years old :D +1 on delete

@ElderGeek No, sadly, I don't have an alternative! The entire answer was based on false grounds!

2:54 PM

Then put a disclaimer at the top :=

@Rinzwind Thanks. I'm not sure how that fell through the cracks..

imagine someone doing that with 100 users _O-

@Rinzwind assuming that's for me, I'll do so immediately.

@DKBose yes sir. Just put it at the top. maybe TS comes back maybe not

@Rinzwind No doubt! What a mess. @DKBose disclaimer yes that's for you

2:55 PM

@DKBose do not dare to yes caps! :=D

or italics. or underline

@Rinzwind removed the caps!

WinEunuuchs2Unix

@Rinzwind Your answer from Feb 25, 2013 has no code block ticks: askubuntu.com/a/261280/307523 was this when you first joined Ask Ubuntu? Funny thing is I'm thinking of getting my one Windows for Steam game running in Linux for Steam this week and I stumbled across your old answer.

A: Under what conditions can accepted answers be deleted?

As the FAQ notes, moderators and 20K "trusted" users can delete accepted answers. 20K users can only vote when the answer score drops below 0. Authors, however, cannot delete their own answers if accepted: When can't I delete my own post? You can't delete answers that have been accepted...

WinEunuuchs2Unix

3:30 PM

@EliahKagan We got enough 20K users in this room to delete his answer then :)

@EliahKagan Oh!

@WinEunuuchs2Unix Its score would still have to be negative.

@DKBose We'll have to downvote you first and then we can delete!

Want to go down that road???

@EliahKagan so can someone please delete my answer? No problem with the downvotes if it's required!

@Fabby please do!

OK...

3:33 PM

@DKBose Can you add an explanation for why it's wrong? Even in comments on the post would be fine. It could be brief. If you do that, I think enough downvotes could be garnered. In particular, I'd be willing to downvote and vote to delete under those circumstances.

First downvote is in cc @WinEunuuchs2Unix

Of course, at this rate, how can I overtake Rinzwind?

2

@EliahKagan in brief: The window title changes if, for example, I change directories!

That throws the whole thing out the window.

Ah, I see. You have commented, just on the question. I've upvoted that comment so people who wonder why your answer was deleted will be able to figure it out easier. I'll add my downvote to your answer. Thanks! [Update: Delete vote cast.]

@WinEunuuchs2Unix Thank you!

WinEunuuchs2Unix

@EliahKagan It's negative now :) askubuntu.com/questions/1159427/…

Second delete vote cast!

@DKBose None of us can overtake @Rinzwind we might as well meet at the bar and complain about it over beers.

3:38 PM

@WinEunuuchs2Unix I can dream, can't I?

@WinEunuuchs2Unix I think I'll have breakfast before the beer ;-)

@ElderGeek there were times breakfast was flat beer and left-over pizza!

@DKBose deleted

Thanks all!

That was fun actually :)

@DKBose I remember those days. I can't say I miss them.

@WinEunuuchs2Unix not really for me ;) I spent a long time getting that gif to the right size :(

WinEunuuchs2Unix

@DKBose Well we could edit the answer and say "I tried this with xtool and it doesn't work" then we can undelete and upvote :)

No mods are around to see our dirty deeds!!!!

:)

@WinEunuuchs2Unix Nah! Thanks all the same.

WinEunuuchs2Unix

3:45 PM

You know for gifs there is a handy on-line compression tool. You upload your gif to website and it shrinks it to fit in stack exchange 2MB limit.

@WinEunuuchs2Unix but by how much can these sites do so? Any idea? I saw someone use giphy or something like that. I usually make my own with ffmpeg/imagemagick.

It looks like the story of sudo and $HOME in Ubuntu will be taking yet another dramatic turn.

As 17.10 approaches, I think various questions (like this one) will need additional answers and/or extensions to some of their existing answers.

WinEunuuchs2Unix

@DKBose I guess it depends how efficient the gif maker is in the first place. I use peek which is pretty effficient.

@EliahKagan What 17.10 is coming out? I'll have to upgrade my 16.04 soon :P

@WinEunuuchs2Unix I have peek but it seems to work better on GNOME and not so well on KDE.

@WinEunuuchs2Unix Well, you should upgrade it by April 2021. :)

Q: Unknown display + no sound on upgrading kernel to 4.18 (Ubuntu 18.04)

I am running a Dell Optiplex 7060 with Ubuntu 18.04 (dual-booted with Windows). The system only has Intel's iGPU (UHD Graphics 630) to which I have two monitors connected, and it uses the Realtek ALC3234 audio controller. Both monitors and the sound were working without issue with the kernel 4.1...

ubuntu kernel audio display realtek

WinEunuuchs2Unix

@DKBose Probably right. The DK in DK Bose stands for "Desktop KDE" :)

@WinEunuuchs2Unix, no it's from a Hindi movie. Kulfy gets what it means ;)

WinEunuuchs2Unix

@EliahKagan I have high hopes that 20.04 will be a perfect upgrade and offer direct conversion from 16.04 in ground breaking developmental leap.

^^^ I was being facetious btw.

I know. :)

I was thinking 20.04 would be the release where the X.org and Wayland projects will merge and become the same thing. :)

(I am also kidding.)

@EliahKagan well in many respects walyand is still to imature to be used especially when it comes to screencasting/screenrecording

4:00 PM

Is it the default in any releases?

@EliahKagan it was default in 17.10 and it was a desaster then canoncal steered back and made xorg default again

@WinEunuuchs2Unix Sorry, I meant 19.10 of course.

I keep forgetting what year it is.

I wonder what will happen to the Conky addicts then!

Well, I don't think X.org is being dropped from Ubuntu anytime soon, is it?

Regarding the above... the sudo/$HOME situation is already confusing. It's widely believed that gksu/gksudo is no longer relevant and that if one must run graphical programs as root the only reasonable options are sudo -H and sudo -i. This isn't true, because 16.04 LTS still has gksu/gksudo, though it is true for most supported releases.

For about a year and a half, we'll have a supported release (16.04) that still has gksu and another supported release (19.10) where sudo behaves the same as sudo -H (unless reconfigured otherwise).

4:19 PM

How would one go about listing all values from all keys in gsettings in one command?

gsettings get org.gnome.settings-daemon.plugins.xrandr < $(gsettings list-keys   org.gnome.settings-daemon.plugins.xrandr )

obviously doesn't work, but how would you call one program multiple times for multiple lines of output?

Question time???

Meh... Doom time!

@Fabby Here's one way:

gsettings list-keys org.gnome.settings-daemon.plugins.xrandr | xargs -n 1 gsettings get org.gnome.settings-daemon.plugins.xrandr

I"m an idiot! Thanks!

You're not an idiot! But you're welcome!

:)

xargs is more commonly used when the goal is to build a long argument list. But with -n 1 it works for running a command multiple times with one argument each time.

WinEunuuchs2Unix

@Fabby You're researching .xrandr like I did: gsettings list-recursively | grep .xrandr

@EliahKagan I should read the man page for xargs

4:30 PM

I should probably have included -d '\n' in that xargs command. I think lines in the output of list-keys could contain whitespace.

@EliahKagan The difference between an amateur and a pro: xargs

and RegEx.

0:-)

:)

WinEunuuchs2Unix

xargs = beginner, parallel = advanced because it splits xargs to multiple CPUs.

@WinEunuuchs2Unix There's also xargs -P.

time echo {1..7} | xargs -n1 -P4 sh -c 'echo starting "$1"; sleep "$1"; echo stopping "$1"' _

Q: What's a good back-up strategy for 1 desktop PC?

No, this is not a comparison of back-up tools, nor is it a solicitation on What to backup or Why and only a little bit about Where to backup and When to do it. This is basically a strategy question: what, where and when all together. "How" is not really relevant: there are tons of back-up progra...

@Fabby thank you for explanation.

what is your employment? some IT stuff?

I'm an IT guy's worst nightmare or best thing since sliced bread:

I'm a Technical Manager.

I'm a pensioner. without IT background, a common user.

@Bahamut You shoud update your profile, because if I look at yours, I see:

actually I'm nobody. This is profile from my old account. It seems to get merge with my new account.

6:07 PM

@Bahamut You should be able to set a main profile though...

It is not so important. and I did not know how.

I'am the guy with many faces. :D

How can I retract a rejected edit???

@Fabby I think the best thing is just to ask other people to review it, as you've done.

WinEunuuchs2Unix

9:28 PM

@Fabby I made the edit for you. But you could have done the same???

Oops guess I could have simply approved it? :)

9:40 PM

@WinEunuuchs2Unix I think your edit was good. I didn't notice how to improve the wording so I just clicked Approve instead of Edit.

WinEunuuchs2Unix

@EliahKagan I'm not very good at this but I've noticed if I approve an edit it takes more votes. If I change one little thing though it gets saved right away.

Yeah, clicking Edit immediately applies it.

I think there are two reasons for that. One is that it would be really cumbersome if your own edit had to be approved by someone else, especially considering that you can edit posts yourself without approval anyway. The other, which I think I recall Shog9 mentioning, is that clicking Edit and editing is unlikely to be done out of haste or inattention and doing so credits the editor in the post history and makes them pingable from comments on the post in case someone has concerns about the edit.

Unfortunately, I am not managing to find that the post (that I think exists) by Shog9 that I was thinking of. So I might be getting the rationale wrong.
