[00:10] <JohnMD> Oracle virtualbox lubuntu boinc
[00:11] <wxl> JohnMD: your what hurts?
[00:13] <JohnMD> Thanx vxl. I want to run more than 1 boinc here. I'm sure my setup is OK. but I can't start an extra task via -
[00:14] <wxl> JohnMD: via what?
[00:14] <JohnMD>  /usr/bin/boinc --daemon --allow_multiple_clients --gui_rpc_port 31422 --dir ~/boinc2/
[00:15] <wxl> i see. why aren't you inquiring with boinc about this?
[00:15] <wxl> (i have no idea how it works)
[00:16] <wxl> i will say it seems silly to me to run multiple DAEMONS. it would make more sense that you would start multiple clients as that switch suggests
[00:16] <wxl> that's not based on experience but just logic
[00:16] <wxl> in any case there's nothing special about lubuntu as it relates to boinc
[00:19] <JohnMD> The command (in LXTerminal - Lubuntu 18.04) seems to have no effect - but is not erroneous.
[00:19] <JohnMD>  This manoevre is NOT standard boinc !
[00:20] <Maik> wxl: looks like there's been a spam attack going on again in channels that don't have the +r flag set up
[00:21] <JohnMD> Forget the daemon - it's a special word in boinc. What do you mean by 'switch' ?
[00:22] <wxl> JohnMD: it's only lubuntu? it works everywhere else? if not, then the issue must lie with what you're doing.
[00:23] <kc2bez[m]> JohnMD:  for general Boinc help go here https://boinc.berkeley.edu/wiki/BOINC_Help
[00:23] <JohnMD> - ot in Windows, Oracle, Virtualbox !
[00:23] <wxl> this suggests you have to sudo it https://efmer.com/linux-running-multiple-boinc-clients/
[00:24] <wxl> which makes sense as you are binding a port
[00:26] <wxl> if "ot" is supposed to mean offtopic, yes, that makes sense. it's very ON TOPIC at boinc XD
[00:27] <wxl> i'll also add that since it requires networking and you're using a virtual machine, you would want to make sure that you have your networing set up in a compatible way
[00:34] <JohnMD> "sudo" worked.*
[00:34] <JohnMD> The problem seems to be that the new task runs under "root" - and not my logon
[00:35] <wxl> `sudo sudo -c "your command" your-username`
[00:41] <JohnMD> twice sudo ?
[00:43] <JohnMD> I guess I need to cancel the task I started...
[00:43] <wxl> ooops i meant `sudo su`
[00:43] <wxl> err wait that might not work hold on
[00:44] <wxl> let's review: why does it need to be your logon?
 well to use the GPUs out of the box you can't without suod
 sudo*
 because it needs a group users usually are not in
[00:45] <wxl> right that was my point
[00:45] <JohnMD> Sorry about my delays - I'm writing from my lounge laptop, while Lubuntu is on the desktop in the workroom !
 sudo sudo -c doesn't solve that binding problem so if ANYTHING is using the GPU it should be started as root single sudo
 started as root with single sudo
 less a port binding issue, more the permissions around the device permissions
[00:46] <wxl> i meant `sudo su -c user` meaning "run this as this user" but that won't work
 right
 because *that user* will not have binding privs
[00:46] <wxl> i'm thinking more like `sudo --preserve-env` but i don't know why it needs to be "their login"
[00:47] <JohnMD> Forget gpu - only cpu required :)
 same problem
[00:47] <wxl> why does it need to be under your login?
 most utilities that aren't executed with a system layer at some point can bind to the CPU
 JohnMD: why *specifically* does it need to be under your login?
 (same question as wxl)
[00:48] <JohnMD> I need to connect a manager-program from my user
 that doesn't answer why you can't run the core daemon process as superuser and just connect into it with your manager program
 or are you saying that your manager program doesn't have the rights to when yo urun the daemon with sudo
 (which doesn't really make sense)
[00:49] <wxl> of course boinc doesn't make sense because they call their daemon a client
[00:50] <JohnMD> exactly
[00:50] <wxl> which gets me back to what i was saying before
[00:50] <wxl> ask boinc for help! XD
[00:50] <JohnMD> I'm new to Linux - superuser ??
 wxl: except BOINC has a GUI port that's TCP
 so with the right work you can configure the *client* to connect to the daeon on that TCP port
 that's more a problem with the way BOINC works than what we can do with it
[00:51] <wxl> right
 superuser aka administrative privs.
[00:51] <wxl> the issue isn't about lubuntu. it's about how to use boinc, which i don't think anyone of us now
[00:52] <wxl> LOOK LIVE HELP GO HERE https://boinc.berkeley.edu/help.php
[00:54] <JohnMD> worth a look.
[00:54] <JohnMD> Meanwhile I'll go and try sudo with user :)
[01:23] <JohnMD> sudo user did not work. time for bed.
[01:23] <JohnMD> Thanks to you good people :)
[05:05] <tech> how do get into groups
 Any idea does it make sens to propose changing default for fs.inotify.max_user_watches? And where it can be done?
 Both Android Studio and Codium (and therefore also Visual Studio Code) complain that default is too low - see https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc
 I know how to change default for my install, but I wanted to propose changing default on fresh installs.

[22:27] <nixnine> I have a problem with my computer freezing.
[22:28] <wxl> mouse doesn't respond?
[22:28] <nixnine> Yes!  Mouse doesn't move and sometimes it seems to freeze when I start typing on the keyboard.
[22:29] <wxl> if you hit e.g. ctrl-alt-f4 does it respond by taking you to a login prompt?
[22:29] <nixnine> I am not sure.  I haven't tried that.  I will note that now.
[22:29] <wxl> if it does then you're not frozen and something else is going on
[22:30] <wxl> if it doesn't, you're almost unquestionably frozen for sure
[22:30] <wxl> if that's the case, check your disk light. if it's going off like mad and/or constant, it's obviously stuck
[22:30] <wxl> a common cause of that could be that you've run out of memory and the system is swapping like crazy (i.e. trying to use the disk as ram)
[22:31] <wxl> ((ram is more responsive than the disk, thus the problem))
[22:31] <nixnine> Ok.  Can I check that usage?
[22:31] <wxl> there's lots of ways, yes
[22:31] <nixnine> oh
[22:31] <wxl> how much ram do you have?
[22:31] <nixnine> just 8gb
[22:31] <wxl> that's a fair amount actually, at least for lubuntu
[22:32] <nixnine> oh.  I may be in the wrong place.  I am using ubuntu studio
[22:32] <wxl> yep you sure are :)
[22:32] <wxl> Eickmeyer[m]: ^ this one's yours :)
[22:33] <wxl> all of the above still apples though
[22:33] <Eickmeyer[m]> Which version?
[22:33] <nixnine> I just installed 20.04 lts
[22:33] <Eickmeyer[m]> Hmmm.... nothing else running?
[22:34] <nixnine> as in?
[22:34] <nixnine> programs?
[22:34] <Eickmeyer[m]> Well, are you just running the desktop and no applications when this is happening?
[22:34] <nixnine> No, I am usually using Gimp
[22:34] <nixnine> or just on the internet
[22:35] <Eickmeyer[m]> Interesting. Likely it's just processing something in the background. Ubuntu Studio is made for high-power machines, so if you're doing intensive stuff (like, ultra-high res with GIMP), then that could cause that.
[22:36] <nixnine> Yeah.  They are usually big files.
[22:36] <Eickmeyer[m]> Yep, GIMP basically uncompresses what might be small files and if they're high resolution, you're probably just experiencing swap.
[22:37] <nixnine> Yeah.  Usually my files are 7200 X 3200, 900 dpi.
[22:38] <Eickmeyer[m]> Yes, then that explains it. 8G, believe it or not, is too small to handle that.
[22:38] <nixnine> Ok.  Need more ram then
[22:38] <Eickmeyer[m]> So, while it's swapping stuff out to RAM (to keep your system from freezing completely) it's taking all of its priority to do that swap.
[22:38] <Eickmeyer[m]> That's what it sounds like.
[22:40] <nixnine> Ok.  Well, thanks.  I will see what happens if I use smaller files.
[22:41] <Eickmeyer[m]> Good luck! In the future, go to #ubuntustudio for support requests there.
[22:42] <nixnine> can you offer help on connecting a printer?
[22:42] <nixnine> I have a printer connected via usb but it says the printer is not connected
