| JohnMD | Oracle virtualbox lubuntu boinc | 00:10 |
|---|---|---|
| wxl | JohnMD: your what hurts? | 00:11 |
| 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 - | 00:13 |
| wxl | JohnMD: via what? | 00:14 |
| JohnMD | /usr/bin/boinc --daemon --allow_multiple_clients --gui_rpc_port 31422 --dir ~/boinc2/ | 00:14 |
| wxl | i see. why aren't you inquiring with boinc about this? | 00:15 |
| wxl | (i have no idea how it works) | 00:15 |
| 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 | 00:16 |
| 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 ! | 00:19 |
| Maik | wxl: looks like there's been a spam attack going on again in channels that don't have the +r flag set up | 00:20 |
| JohnMD | Forget the daemon - it's a special word in boinc. What do you mean by 'switch' ? | 00:21 |
| wxl | JohnMD: it's only lubuntu? it works everywhere else? if not, then the issue must lie with what you're doing. | 00:22 |
| 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/ | 00:23 |
| wxl | which makes sense as you are binding a port | 00:24 |
| wxl | if "ot" is supposed to mean offtopic, yes, that makes sense. it's very ON TOPIC at boinc XD | 00:26 |
| 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 | 00:27 |
| JohnMD | "sudo" worked.* | 00:34 |
| JohnMD | The problem seems to be that the new task runs under "root" - and not my logon | 00:34 |
| wxl | `sudo sudo -c "your command" your-username` | 00:35 |
| JohnMD | twice sudo ? | 00:41 |
| 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 | 00:43 |
| wxl | let's review: why does it need to be your logon? | 00:44 |
| lubot | [telegram] <teward001> well to use the GPUs out of the box you can't without suod | 00:45 |
| lubot | [telegram] <teward001> sudo* | 00:45 |
| lubot | [telegram] <teward001> 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 ! | 00:45 |
| lubot | [telegram] <teward001> sudo sudo -c doesn't solve that binding problem so if ANYTHING is using the GPU it should be started as root single sudo | 00:46 |
| lubot | [telegram] <teward001> started as root with single sudo | 00:46 |
| lubot | [telegram] <teward001> 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 | 00:46 |
| lubot | [telegram] <teward001> right | 00:46 |
| lubot | [telegram] <teward001> 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" | 00:46 |
| JohnMD | Forget gpu - only cpu required :) | 00:47 |
| lubot | [telegram] <teward001> same problem | 00:47 |
| wxl | why does it need to be under your login? | 00:47 |
| lubot | [telegram] <teward001> most utilities that aren't executed with a system layer at some point can bind to the CPU | 00:47 |
| lubot | [telegram] <teward001> JohnMD: why *specifically* does it need to be under your login? | 00:47 |
| lubot | [telegram] <teward001> (same question as wxl) | 00:48 |
| JohnMD | I need to connect a manager-program from my user | 00:48 |
| lubot | [telegram] <teward001> that doesn't answer why you can't run the core daemon process as superuser and just connect into it with your manager program | 00:49 |
| lubot | [telegram] <teward001> or are you saying that your manager program doesn't have the rights to when yo urun the daemon with sudo | 00:49 |
| lubot | [telegram] <teward001> (which doesn't really make sense) | 00:49 |
| wxl | of course boinc doesn't make sense because they call their daemon a client | 00:49 |
| 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 ?? | 00:50 |
| lubot | [telegram] <teward001> wxl: except BOINC has a GUI port that's TCP | 00:50 |
| lubot | [telegram] <teward001> so with the right work you can configure the *client* to connect to the daeon on that TCP port | 00:50 |
| lubot | [telegram] <teward001> that's more a problem with the way BOINC works than what we can do with it | 00:51 |
| wxl | right | 00:51 |
| lubot | [telegram] <teward001> 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 | 00:51 |
| wxl | LOOK LIVE HELP GO HERE https://boinc.berkeley.edu/help.php | 00:52 |
| JohnMD | worth a look. | 00:54 |
| JohnMD | Meanwhile I'll go and try sudo with user :) | 00:54 |

| JohnMD | Thanks to you good people :) | 01:23 |
| tech | how do get into groups | 05:05 |
| lubot | [telegram] <matkoniecz> Any idea does it make sens to propose changing default for fs.inotify.max_user_watches? And where it can be done? | 06:11 |
| lubot | [telegram] <matkoniecz> 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 | 06:11 |
| lubot | [telegram] <matkoniecz> I know how to change default for my install, but I wanted to propose changing default on fresh installs. | 06:11 |

| nixnine | I have a problem with my computer freezing. | 22:27 |
| 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. | 22:28 |
| 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 | 22:29 |
| 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) | 22:30 |
| 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 | 22:31 |
| 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 :) | 22:32 |
| 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? | 22:33 |
| 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 | 22:34 |
| 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. | 22:35 |
| 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. | 22:36 |
| nixnine | Yeah. Usually my files are 7200 X 3200, 900 dpi. | 22:37 |
| 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. | 22:38 |
| nixnine | Ok. Well, thanks. I will see what happens if I use smaller files. | 22:40 |
| Eickmeyer[m] | Good luck! In the future, go to #ubuntustudio for support requests there. | 22:41 |
| 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 | 22:42 |
