locsmifHi all. How do I get rid of the weird keyboard which completely fills my screen when I login, and I mean permanently, not by "clicking it away" every time? Solutions online which reference sddm.conf don't work.08:05
TJ-Sounds like the accessibility keyboard09:19
Guest95hmmm.. anyone notice the difference between https://kubuntu.org and https://www.kubuntu.org? is it intentional?10:28
mparilloI will ask.10:31
Guest95thanks10:32
RikMillsGuest95: I am asking canonical sysadmins about that10:39
johncan I get some help?11:33
johnhello?11:34

alkisg!ask11:40
ubottuPlease don't ask to ask a question, simply ask the question (all on ONE line and in the channel, so that others can read and follow it easily). If anyone knows the answer they will most likely reply. :-) See also !patience11:40
John1234Ok. I have a kubuntu 21.04 setup and it has slow DNS lookup... I have a dual boot with a linux mint install and everything is super fast there! I am on fibre. What can I do to make it faster? Howcome KDE cannot just work out of the box. I did resolvconf --status and it says the nameserver is 127.0.0.58.. I just want it to work... howcome I have to start tinkering now? I really like Plasma, but like this, it is getting11:43
John1234annoying and I am considering moving back to mint11:43
John1234!patience11:44
ubottuDon't feel ignored and repeat your question quickly; if nobody knows your answer, nobody will answer you. While you wait, try searching https://help.ubuntu.com or https://ubuntuforums.org or https://askubuntu.com/11:44
alkisgJohn1234: upload the output of `resolvectl` in both of these distributions11:50
alkisgSo that we can compare it11:51
John1234kubuntu: https://pastebin.com/frU2f8dp11:52

John1234hi11:54
John1234192.168.188.1 is my fibre modem, to which I connect via a router called fritzbox, to which I have my pc connected with an ethernet cable11:54
John1234let me go offline for a minute to boot into the other system11:55
alkisgJohn1234: well you appear to be using that as a dns server, so I don't see how it would behave differently when switching distributions11:55
mparilloCould there be two different browser configurations, and one uses your system dns resolver, and one uses a dns resolver set by the browser?12:00
johnthis is the linux mint resolvctl thing:12:00
johnhttps://pastebin.com/jdDyweUP12:00
johnlooks pretty similar12:00
johnI do not know what I missed in the last 5 minutes12:00
johnthe DNS servers are similar12:00
alkisgjohn: are you dual booting these two distributions?12:00
johnyeah12:01
johnthey are on 1 pc12:01
alkisgYes the DNS servers are similar, although in your kubuntu, it said "foreign", that you're not using the normal stub resolv.conf, so let's see:12:01
johnin the linux mint part there is more text under "global", but I do not know what that stuff is12:01
alkisg1) ls -l /etc/resolv.conf; cat /etc/resolv.conf ==> for mind12:01
alkisg2) sudo mount /dev/sda3 /mnt; ls -l /mnt/etc/resolv.conf; cat /mnt/etc/resolv.conf ==> for kubuntu12:02
alkisgReplace sda3 with your kubuntu partition name12:02
johnwhere does the "foreign" come from? and what does it mean? why does Kubuntu make it such, it obviously does not work, mint just works out of the box12:02
alkisgYou can see it with `sudo lsblk --fs`12:02
alkisgIt means that you manually modified resolv.conf12:02
alkisgKubuntu didn't do that12:02
johnI did not manually modify my resolv.conf12:02
alkisgPaste the output of the commands so that we see12:02
johnfor mind ???12:03
alkisgfor mint12:03
alkisgtypo12:03
alkisgI.e. (2) is a way to provide information for your kubuntu, without rebooting12:04
johnhttps://pastebin.com/MuWXmp3j12:04
johnthis is resolv.conf in mint12:04
alkisgPaste also the output of the first command, the ls -l one12:05
alkisgSo that we see if it's a symlink or not12:05
BluesKajHi folks12:06
alkisgo/12:07
johnnow I cannot find resolv.conf in the /etc directory of the kubuntu install12:07
johnfirst command yields: lrwxrwxrwx 1 root root 29 Sep 22 03:22 resolv.conf -> ../run/resolvconf/resolv.conf12:08
alkisgjohn, see the ls part12:08
alkisgls -l /etc/resolv.conf12:08
alkisgand ls -l /mnt/etc/resolv.conf12:08
alkisgIf it's a symlink, it's normal to be unable to `cat` it12:08
johnI cannot even ls it12:08
johnresolv.conf is not there in the kubuntu dir12:08
alkisgOK, so mint is using the old resolvconf. That's not really a good thing12:09
johnit works fine !!12:09
johnit is kubuntu that is the problem12:09
alkisgI understand what you're saying12:09
alkisgTry to understand what I'm saying12:09
johncan you explain it please12:09
alkisgReboot to kubuntu, I'll wait for a few minutes12:09
johnsorry...12:10
johnI did the ls -l resolv.conf command in the /mnt/kubuntu/etc dir12:10
johnso that is kubuntu12:10
johnlrwxrwxrwx 1 root root 39 May  8 01:58 resolv.conf -> ../run/systemd/resolve/stub-resolv.conf12:10
johnthis is the mint output12:10
alkisgAnd what about your mint?12:11
alkisgOK. Now do this: chroot /mnt dpkg -l | grep resolvconf12:11
alkisgwith sudo in front12:11
alkisgsudo chroot /mnt dpkg -l | grep resolvconf12:11
johnthat kubuntu parition is under /media12:12
lumo_ehello12:12
johnwhat does that command do?12:12
alkisgIt checks your kubuntu installation to see if a package named resolvconf is installed12:13
alkisgIn a default installation, it's not12:13
alkisgSo it was installed manually; for example, maybe you installed some other package that recommended it12:13
johnI installed bind912:13
johnto try to solve it??12:13
lumo_eI'm trying out ubuntu 21.10 with plasma beta 5.23, I was using gnome(stable) before and X11 wasn't really working already, but wayland worked12:13
alkisgjohn, bind9 is if you want to create your own internet dns server12:13
johnso I should do chroot /media dpkg -l | grep resolvconf ?12:14
lumo_eI changed from gdm3 to sddm, and it seems that the X11 bugs that I had before now are much worse12:14
alkisgIt's not for users, it's for companies with large intranets etc12:14
johnwell some people recommanded it12:14
lumo_ebasically, my keyboard doesn't work and my touchpad barely works12:14
lumo_eboth inside sddm and the plasma/xorg session12:14
alkisgjohn: if it's a fresh installation, I'd recommend to redo it from scratch, AND ignore those people :)12:14
johnit is not a fresh install12:15
lumo_eeither the keyboard doesn't work or it will send repeated keys for whatever reason12:15
johnand I have got it all set up12:15
alkisgbind9 would have pulled a lot of services that would take some time and experience to clean up12:15
alkisgOK12:15
lumo_eif I manage to very carefully use the onscreen keyboard, I can login to wayland, and that works12:15
johnwhat exactly is the problem with my install now???12:15
lumo_ehow can I even debug this?12:15
alkisgAnyway, you need to remove bind9 and resolvconf and let systemd-networkd do its job, like it does in mint, like it does in the default kubuntu12:15
alkisgjohn,  you made your pc a dns server, instead of a dns client12:15
johnbut that problem existed even before bind912:16
johnthat is why I tried bind912:16
alkisgjohn: that would be a different issue though. This one is a much bigger problem12:16
johnI go to the package manager to remove bind9 server and resolvconf ?12:16
johnlet me go back to kubuntu12:16
johnwait12:16
BluesKajtry settings in /etc/systemd resolved.conf12:16
alkisgjohn: I can't give instructions for that, as you may remove them and break something else12:16
alkisgjohn: you need someone with more time :)12:16
* alkisg needs to go for now, back later!12:17
johnhowcome this got screwed up so much?? I never changed anything big, then the dns look up got really slow!!12:17
johnI only installed bind9 to try to solve it, but the problem was there even before12:17
johnthe problem cannot be to do a complete reinstall, that will take hours12:17
johnlet me go back to kubuntu12:18
johnback12:19
=== john is now known as john1235
john1235I should remove resolvconf too?12:20
BluesKajjohn1235, I suggested settings in /etc/systemd/resolved.conf12:21
john1235it is empty12:22
BluesKajis this Kubuntu or mint?12:22
john1235https://pastebin.com/QiyezdUn12:22
john1235I am in kubuntu now12:22
BluesKajare there options listed there like DNS etc12:23
BluesKaj?12:23
john1235oh wait12:23
john1235sorry12:24
BluesKajuncoment tyje options you want use and add the IP/settings there12:25
john1235let me check that file in mint12:25
john1235in mint it is empty too12:26
john1235howcome it works in mint and not in kubuntu12:26
john1235maybe because of what alkisg said?? maybe it is not using the systemd ??12:27
BluesKajjohn1235, this is my /etc/resolv.conf , it's astub now https://bpa.st/56ZA12:29
john1235well in my /etc/resolv.conf it says that my nameserver is 127.0.0.53 too, but obvisouly that does not work12:30
BluesKajright because /etc/resolv.conf is no longer used12:30
BluesKajthanks to systemd12:31
john1235but alkisg said that on my system it IS being used12:31
john1235lrwxrwxrwx 1 root root 29 sept. 22 03:22 resolv.conf -> ../run/resolvconf/resolv.conf12:32
BluesKajyeah, I'm surprised he said that12:32
john1235why are you surprised12:32
john1235that is the result of ls -l /etc/resolv.conf12:33
john1235on mint it pointed to another file12:33
BluesKajafaik /etc/resolv.conf is redundant12:33
john1235lrwxrwxrwx 1 root root 39 mai    8 01:58 resolv.conf -> ../run/systemd/resolve/stub-resolv.conf12:33
john1235that is mint12:33
oerheksmint issue?12:33
oerhekslolz12:33
john1235on mint it works fine12:33
john1235no mint points to systemd12:34
john1235it is kubuntu that points to /run/resolvconf/resolv.conf12:34
john1235I do not even understand the difference....12:34
oerheksthen do not compare kubuntu with mint, and focus on your kubuntu issue?12:34
john1235I wanna do it12:34
john1235but I do not understand the architecture.. how thinks this up???12:34
john1235what are the program that use these files? and if there are stubs everyhwere, where are the REAL configuration files?12:35
BluesKaj afaik /etc/systemd/resolved.conf supposed relaced it12:35
BluesKajsupposedly12:35
john1235what program uses that file??12:35
john1235what process?12:36
john1235the kernel?12:36
BluesKajnetwork manager I think12:36
john1235I guess I will actually have to reinstall12:36
oerhekssystemd-resolve --status , this service is controlling it12:36
john1235maybe if i remove resolvconf?12:38
BluesKajI have my DNS settings entered inmy router DNS options so i don't bother with system resolved12:39
BluesKajsystemd resolved that is12:39
john1235but your computer needs to know where to look for the dns lookup12:41
john1235doesn't it??12:41
oerheksi read back, you installed bind9 ?12:41
oerheksand what else?12:41
john1235I uninstalled bind9 now12:42
john1235nothing else12:42
john1235only the server part though12:42
john1235not the client part12:42
john1235but the problem existed before bind0912:43
john1235I think I will try to remove resolvconf12:45
BluesKajdon't think that will make any difference12:45
john1235I now selected 8.8.8.8 and 8.8.4.4. in my router12:47
john1235let me see if that makes a difference12:48
john1235seems to work better now12:49
john1235werid12:49
john1235but now all my dns look ups are done through google!!12:49
john1235https://askubuntu.com/questions/985336/why-there-are-resolvconf-service-and-systemd-resolved-service-services-present-i12:49
john1235ok so that did the trick12:51
BluesKajthere are other DNS servers like cloudflare or even some other private DNS servers in your country I'm sure. I use a couple of University servers here in Canada12:51
john1235I still do not understand why it cannot work normally on a kubuntu install and it DOES work on a mint install, with the "recommended DNS servers" on the router12:52
john1235I searched for the dns servers of my ISP and they work too12:52
john1235but still weird that kubuntu would screw up like this12:52
BluesKajdo you use networl manager?12:52
BluesKajnetwork manager12:52
john1235I do not know12:54
johnlet me reboot12:56
=== john is now known as john1236
john1236ok12:58
BluesKajcheck your package manager for network-manager12:59
john1236yeah, it is installed13:00
john1236I removed resolvconf13:00
john1236but when I change back to the recommended DNS server in the router it is slow again13:00
john1236and also the ls -l /etc/resolv.conf still points to ../run13:00
john1236It might be time to finally use a vpn13:01
john1236that handles DNS13:01
john1236I might try a live kubuntu cd now13:02
john1236mom13:02
BluesKajbrb13:05
johnstill the same thing13:14
johnalso under the live cd13:14
johnthis is a kubuntu problem!!!13:14
IrcsomeBot<rs2009> sudo apt install nm-applet && nm-applet (re @IrcsomeBot: <john> this is a kubuntu problem!!!)13:16
IrcsomeBot<rs2009> Oops, went through the messages and guess it won't help13:17
johnok, thanks guys, for the help13:21
BluesKajjohn, is your DNS resolving more quickly now?13:23
johnwell... under the live cd I had the same problem, and the ls -l /etc/resolv.conf point to ../run/systemd/........ in both the live cd and the regular kubuntu install... the only way to get faster dns is to set the DNS servers in the router... but linux mint works fine even with the "recommended DNS server"-setting in the router... so this seems to be a kubuntu problem13:25
johnso it works fast under kubuntu only when I select my own dns servers in the router13:25
johnthese 5 second delays every 5 seconds were starting to annoy me..13:26
johnso it is working now, but still I does not increase my trust in kubuntu13:26
johneven though I like the plasma surface better then MINT, mint works better "under the hood", that is my impression13:26
johnI could try ubuntu too, to see if the same problem arises there13:26
johnthen it would be more of  a ubuntu config problem13:26
johnbut mint is based on ubuntu too, but they only use the package base, they do their own thing13:27
BluesKajI've run mint in the past,  it was ok but nothing special IMO13:29
johnwell... I changed to mint after kubuntu was such a buggy experience13:30
johnI used mint for years13:31
johnbut now I got back to kubuntu because it has really improved, especially the updates13:31
johnbut now i am beginning to remember why i moved to mint13:31
johnmint is just a very good install13:31
johnit just works13:31
johnbut it is not as pretty as kubuntu13:31
BluesKajthe reason I set my DNS in the router was because the default settings there went thru the ISP own DNS server thus blocking my vpn so I changed the settings on the first day I received their router  :-)13:33
johnwell good for you that you can even change the DNS13:33
johnin your router13:33
johnin mine that doesn't even seem possible13:33
BluesKajmost users can13:34
johnI will try the live cd of ubuntu now13:34
BluesKajjust need the gateway IP to access13:34
johnyeah13:37
johnI guess the standard for all DNS requests is to be sent to the gateway13:38
BluesKajset your own username and pw13:38
johnmy router only lets me define dns local13:38
johnso local aliases13:38
johnnot the dns server itself13:39
alkisgjohn, which mint version are you comparing to which kubuntu version?13:41
johnthe latest13:41
johnlatest version of mint13:41
johnI just upgraded yesterday13:41
alkisgI'm not using mint, so that's like ubuntu 20.04 then?13:41
john20.2 mint13:42
alkisgBut which ubuntu version is it?13:42
alkisgMint is just ubuntu with a few tweaked packages13:42
alkisgOK let me google it...13:42
johnit is based on ubuntu 20.04 lts yes13:42
johnI do not think mint is just plain ubuntu with some tweaks, it runs way better13:43
alkisgOK. So the most probable cause is that systemd-networkd updates make DNS behave differently in your router13:43
alkisgMint doesn't have enough developers to work on things like networking13:43
alkisgThis is done by systemd developers13:43
alkisgFor example, maybe it doesn't like your router as a DNS server, and looks for authoritative answers, for validation13:44
alkisgThat's just an assumption. To compare, you'd need to compare the same systemd versions, not different ones13:44
alkisgIn any case, you can set any DNS server you like in the network-manager connection properties13:44
johnwhere do I set those connection properties??13:45
alkisgYou right click in the network icon in the applet13:45
johnalkisg: but that is the normal situation I think, that the linux install uses the DNS server of the router13:45
alkisgYes, indeed.13:46
alkisgBut `resolvectl` output is very different in 20.04 vs 21.0413:46
alkisgI believe many things have changed under the hood; maybe what you're seeing is  related to systemd updates13:46
johnhmmmmm13:47
johnkde 21.04 you mean?13:47
alkisgSo in the connection properties, there's an IPv4 tab, where you can select "auto, ips only" or something (I'm using a translated UI)13:47
alkisgThe desktop environment isn't related13:47
alkisgI mean any ubuntu 21.0413:48
johnwell I was considering going back to 20.04 for my fresh kubuntu install anyway because 21.04 is only supported until january, a bit short!13:48
alkisgThese base things are common to all distros13:48
alkisgRight, so if you use kubuntu 20.04, it should have the same systemd as your mint13:48
alkisgCan you check from the live cd there?13:48
alkisgBtw, I read your chat above; /etc/resolv.conf is USED by libc and all networking libraries13:49
alkisgThat stub file is generated by systemd, but it's essential; without it, no DNS works13:49
johnok13:49
johnthanks13:49
johnI go to "ipv4" and I chan choose method13:50
alkisgIt means that systemd itself is now the primary dns server (which in then asks the router dns server)13:50
johnit is automatic13:50
alkisgYou can select auto / ips only or something like that13:50
alkisgAnd add the DNS in the text below13:50
alkisgAutomatic (only addresses) or something13:50
johnthere is auto adresses only13:50
alkisgRight, that one13:50
alkisgThen you can set your DNS in the box below13:50
johnwhat is the difference to auto?13:50
alkisgAuto means from dhcp, which means your router13:51
johnstill I do not get why it would not work using my router's DNS13:51
johnthat is weird13:51
alkisgauto (addresses only) means your router sends the IP, but not the DNS; you hardcode the DNS to the one you like13:51
johnthe IP means the data??13:51
alkisg"changes to systemd"13:51
johnok13:52
alkisgFor now, you'll probably be able to use 20.04 with no delays etc, like in mint,13:52
alkisgwhile in 22.04, if the issue happens there in both mint, kubuntu and all, you'll need to either hardcode a DNS, or troubleshoot the issue,13:53
alkisgfrom where you may find that you'll need to check some setting in your router, because systemd now needs that, etc etc; we'll see then, it's not important now13:53
johnI am on kubuntu 21.04 but I used that method you suggested and now it is faster, even without the standard dns in the router13:54
johnit is a bug in the new systemd13:54
alkisgIt may be a bug in your router13:54
alkisgYou don't know yet13:54
johnI should not have to change my router if systemd changes, that router has been working fine for years13:54
alkisgAnd maybe the new systemd is safer, and does additional work to resolve the router bug13:55
johnthat is a fritzbox, the leading provider of routers in germany13:55
johnrouter bug13:55
john?13:55
johnwhat is that?13:55
alkisgSo what? http was working fine for years, until all the internet had to change to https13:55
johnok13:55
johnso now I do not have to reinstall, thank goodness13:55
alkisgThere's no point in placing blame yet. It's either systemd or fritz, but we don't know yet.13:55
johnbut what happens if january 2022 comes.. then I will have to reinstall kubuntu.. because no longer supported, or will I be able to upgrade ot another version13:56
alkisgIt's most probably not related to distributions though, and certainly not desktop environments13:56
johnI doubt it is fritz, fritz always offers standard stuff13:56
johnbut ok, you might be right, maybe the standard is flawed13:56
johnbut how hard can it be.. it is just a lookup table nothing more13:56
alkisgFrom kubuntu 21.04 you'd need to update to 21.10 and then 22.0413:57
alkisgNowhere near simple as that13:57
johnwill I be able upgrade in january or have to reinstall my kubuntu 21.04?13:57
alkisgDNS is authoritative, recursive etc etc, it's not a lookup table13:57
alkisgIn October you'll be able to update to 21.1013:57
alkisgIn April you'll be able to update to 22.0413:57
johngreat13:57
alkisgNothing happens in January13:57
johnwell support expires13:57
alkisgAh sure, yeah13:58
johnwhat about the ipv6 tab?13:58
johnis ipv6 already working now???13:59
johnI never understood it13:59
johnif i give in a ipv4 address.. I can still connect, so what about ipv6?13:59
alkisgIt depends on your router AND your isp AND the servers you visit13:59
alkisgIgnore it for now13:59
johnbut if I rent a server I get a ipv4 address13:59
johnnot a ipv6 address, or do I?13:59
alkisgYou can ask for whatever you prefer13:59
johnI am considering renting a server to host my own cloud, but I am not sure if I am knowledgeable enough...13:59
alkisgBut public servers are supposed to have an ipv4 address as many users won't have proper ipv6 networking14:00
johnso ipv6 addresses are actually being given out already?14:00
johnso there are basically 2 adress spaces now???14:00
alkisgYes, they're widely used14:00
alkisgYes14:00
johnhmmm, since when is that?14:00
alkisgEh, google that part, I guess more than a decade14:00
johnwho would have hardware old enough not to understand ipv6?? it has been around for years14:01
alkisgFor example my isp doesn't offer ipv614:01
johnalkisg: where is that?14:01
alkisgWhile my hardware/software/router etc do support it14:01
johnmy router has ipv614:01
alkisgGreek school network :)14:01
alkisgWhile at home, I do have both ipv4 and ipv614:01
johnalkisg: you are in school?14:02
johnyou know a lot14:02
