| Maynard | Hello all | 02:50 |
|---|---|---|
| Maynard | So I have my .iso but choosing the different bootable usb programs has left me REPEATEDLY with grub2(?) not found or casper/linuz/efi not found | 02:52 |
| Maynard | I am SEMI computer savvy btw. I am comfortable in terminal usage. mostly copy/paste though. | 02:53 |
| Maynard | btw it's 16.04.1 so there is no disk utilities, or the typical answers since it's not gnome. It's xfce or xcfe.... whichever. | 02:59 |
| Maynard | I was reading unetbootin causes the grub fail and pendrive (I think )was the casper not found one. | 03:00 |
| OvenWerks | Maynard: I have been using dd if=iso_file of=/dev/sd* (* = whatever the USB stick is) | 03:02 |
| OvenWerks | Maynard: the computer has to be able to boot from usb sticks of course :) strange I should have to say that as I think they all have for around 10 years, but I do have a machine that requires a DVD | 03:03 |
| OvenWerks | (dd requires sudo to run probably) | 03:04 |
| Maynard | no I have built this before on this system. I do have a black spot right where your answer is.... in terminal just type dd if=iso_file of/dev/sdb or do I use the full sdb1 ? | 03:07 |
| Maynard | I have sudo | 03:07 |
| OvenWerks | sdb | 03:07 |
| Maynard | and no need for the full .iso name? | 03:08 |
| OvenWerks | Warning, this will make your first partition on the usb stick the size of the iso | 03:08 |
| OvenWerks | ya the whole iso file name | 03:08 |
| Maynard | this is where I get lost..... | 03:09 |
| Maynard | I know in thte future updates will need more space | 03:10 |
| OvenWerks | After you have installed the iso to your hard drive you may wish to reformat the usb stick if you want to use it for other things. | 03:10 |
| OvenWerks | That doesn't matter, because the dd will print the size of the new iso | 03:10 |
| OvenWerks | *the next dd | 03:10 |
| Maynard | I typically prefer an apt (?) to automatically do this but all have failed so far | 03:10 |
| Maynard | and dd means what? | 03:11 |
| OvenWerks | I have not used an upgrade for a long time | 03:11 |
| Maynard | sorry.... | 03:11 |
| OvenWerks | man dd | 03:11 |
| OvenWerks | :) | 03:11 |
| OvenWerks | dd is a direct raw copy | 03:12 |
| OvenWerks | I don't remember off hand why it was originally called dd | 03:12 |
| Maynard | I want to keep the .iso intact and able to update. it's a mere 4Gb but I use it on several comp. to easily make ubuntu for others | 03:12 |
| OvenWerks | so no problem then | 03:13 |
| Maynard | so you mean updates will make a new ddd? | 03:13 |
| Maynard | dd | 03:13 |
| OvenWerks | no, the iso will be different sizes from release to release. dd doesn't care so long as the total size of the usb stick is less than the iso size | 03:14 |
| OvenWerks | dd is a raw write to the usb stick without regard for partition tables | 03:14 |
| OvenWerks | So it effectively makes it's own partition | 03:15 |
| Maynard | so mine would read " dd if=ubuntustudio-16.04.1-dvd-amd.iso of dev/sdb " exactly as I typed then? | 03:16 |
| OvenWerks | I think it is amd64 not amd | 03:16 |
| Maynard | Roger...never understood dd before. So since it's 4Gb and only 2.6 for iso then it'll just keep adding when I update | 03:17 |
| Maynard | ? | 03:17 |
| OvenWerks | and I think it should be 16.04.2 by now unless you have an older iso. | 03:17 |
| Maynard | correct amd64.iso | 03:17 |
| OvenWerks | dd if=ubuntustudio-16.04.1-dvd-amd64.iso of=/dev/sdb | 03:18 |
| Maynard | For some reason transmission said 16.04.2 was not suported by tracker | 03:18 |
| Maynard | exactly as written? | 03:18 |
| OvenWerks | ok | 03:18 |
| Maynard | as you wrote | 03:18 |
| OvenWerks | I think so... assuming the file is right :) | 03:19 |
| Maynard | I was dbl checking as we were chatting | 03:19 |
| OvenWerks | it will take a while and does not give any indication of activity | 03:21 |
| Maynard | unless you mean as long as it's not corrupt or not 100% | 03:21 |
| Maynard | ok | 03:21 |
| OvenWerks | Ya once it is finished it tells you blocks in and blocks out. they should be the ssame number. | 03:22 |
| Maynard | So I'll just leave it and the usual pop-up to restart will come up when its done? | 03:22 |
| Maynard | OK ok.... I've noticed before the block sizes were different sometimes. | 03:23 |
| OvenWerks | after that you have to boot with the usb stick in. the dd just writes the stick | 03:23 |
| Maynard | both sticks are in. | 03:23 |
| Maynard | I use a 128 as my HD and the 4 as my back up so I don't need to re-download the iso | 03:24 |
| Maynard | LMAO this thing is a Frankenstein. It's from 2006 but hangs with all but the newer gaming laptops | 03:24 |
| Maynard | swapped RAM etc etc | 03:25 |
| Maynard | OK so I would write the dd with both in and then shutdown, then only the 4Gb? | 03:26 |
| Maynard | stupid question. | 03:26 |
| Maynard | the iso is on the 128 Gb | 03:27 |
| OvenWerks | Assuming you wrote the 4 G that is the one you want to boot from | 03:27 |
| Maynard | I'm just starting from scratch cause of all the problems | 03:27 |
| OvenWerks | I'm confused | 03:27 |
| OvenWerks | I would think you are installing to the 128? | 03:28 |
| Maynard | I'm writing from the 128 to the 4G only to turn around and fresh install onto the 4G as a bootable usb. | 03:28 |
| Maynard | That better explained lol | 03:28 |
| Maynard | I will install to the 128 but I want the 4 intact as bootable | 03:29 |
| OvenWerks | ok, I am not sure if that will work, I think an install is around 8g | 03:29 |
| Maynard | Correct. the iso will be a bootable and only 2.6 but the installed one on the 128 WILL be 8ish. As you said. | 03:31 |
| Maynard | I BARELY made a work around on the 128 so that's why I'm starting the iso from the start cause something happened in the iso to bootable usb part. Many times with many programs | 03:32 |
| OvenWerks | I remember trying to install to a 32g usb stick before, but don't remember the details. No swap though. | 03:33 |
| Maynard | So sounds like the dd will try to install not make a bootable usb of the 2.6 G. Do I have that right? | 03:33 |
| OvenWerks | it should make a bootable iso | 03:34 |
| OvenWerks | should boot the same as a dvd with the same iso on it | 03:34 |
| OvenWerks | it is the differentce between writing an iso to a device and installing the system to a device. | 03:35 |
| Maynard | Yeah I did the 32Gb once but every time I mess with swap it crashes everything so now I use the 32 as backup for files. There is no HDD in here. I need a new PC. | 03:35 |
| OvenWerks | The iso will run as it's own install, but you have to manually mount a writable partition to save anything. The iso is not persistant | 03:36 |
| Maynard | Sweet that's what I want. Everything is backed on the 32G and the bootable will be the 4 and then I'll install onto the 128. | 03:36 |
| Maynard | I told you Frankenstein. | 03:37 |
| OvenWerks | I have done some odd things in my time... | 03:37 |
| Maynard | I've never done this in terminal before and it wasn't a persistent, but I could always remember what extras I added and just did it the long way. | 03:38 |
| Maynard | I read making a persistent one and I hate doing partitions.... I always fuck it up. | 03:39 |
| Maynard | oops | 03:39 |
| Maynard | I even tried Gparted | 03:39 |
| Maynard | Kden(?) | 03:39 |
| Maynard | etc | 03:39 |
| Maynard | Thank you for your patience. Dare I even ask how to use the other 1G on the small one to use as the persistent partition? | 03:43 |
| Maynard | LOL or do I just do this and let you get to someone else? | 03:43 |
| Maynard | Cause it WOULD be nice to keep all my extra pkgs there but since I know them if it's complicated I'll just rebuild when I wanna fresh install. | 03:45 |
| Maynard | Could I do the dd thing then use Gparted to make a 1G partition? | 03:46 |
| Maynard | Or once I do that in terminal there is no changing the usb with another partition? | 03:47 |
| Maynard | Did I lose you or are you banging your head on the desk? | 03:56 |
| Maynard | Just answer the 2 ?s before the head banging one and I'll leave you alone. | 03:57 |
| Maynard | no? | 04:06 |
| Maynard | S***bags! Here's what I get: dd if=ubuntustudio-16.04.1-dvd-amd64.iso of dev/sdb dd: unrecognized operand ‘of’ Try 'dd --help' for more information. | 04:12 |
| OvenWerks | Maynard: of=/dev/sdb | 04:35 |
| OvenWerks | Maynard: you are missing both the = and the /before dev | 04:35 |
| Maynard | ok | 04:36 |
| Maynard | no such file now | 04:40 |
| Maynard | arrrrrrrrgh | 04:40 |
| Maynard | unetbootin it is...............I HATE it when I cannot figure out what seems a simple thing to do | 04:45 |
| studio-user823 | i installed windows swtich on ubuntu and my system blocked everything, i had to reinstall my OS | 14:58 |
| studio-user823 | anybody knows how could have been better to uninstall that program and clean my system | 14:59 |
| djzu | Hi there! I badly need help for running Xpra under Ubuntu Studio. Indeed a simple: apt install xpra; xpra start; xpra attach; will fail (core dumped) on Ubuntu Studio while it is working with Ubuntu or Xubuntu. If not Xfce, who is involved in this crash? | 17:32 |
| djzu | Hi jbermudes! I badly need help for running Xpra under Ubuntu Studio. Indeed a simple: apt install xpra; xpra start; xpra attach; will fail (core dumped) on Ubuntu Studio while it is working with Ubuntu or Xubuntu. If not Xfce, who is involved in this crash? | 18:01 |
| OvenWerks | djzu: have you tried ssh -Y? | 18:06 |
| djzu | @OvenWerks: actually from another machine it is working but not from the local machine | 18:07 |
| OvenWerks | djzu: it may be better to ask in #xubuntu as they have the same desktop and the ear of some of the xfce devs | 18:09 |
| OvenWerks | I have only used ssh -Y and VNC myself | 18:09 |
| djzu | OvenWerks: I tried to replicate installing ubuntu xubuntu and ubuntu-studio on virtual machine and the problem is only on ubuntu studio not xubuntu | 18:10 |
| OvenWerks | Interesting. | 18:22 |
| OvenWerks | There is a possibility that it is either xfce settings that differe slightly or more likely that it is a kernel difference | 18:22 |
| djzu | is the kernel different from xubuntu? | 18:23 |
| OvenWerks | It is possible to install the generic kernel on top of Studio and run that and see if that makes any difference | 18:23 |
| OvenWerks | Yes xubuntu uses the standard generic kernel, Studio uses the lowlatency kernel. | 18:24 |
| djzu | I tried to install the lowlatency kernel on top of regular ubuntu and the problem did not appear | 18:24 |
| djzu | I'll try to install the lowlatency kernel on xubuntu this time to see if there is an difference | 18:25 |
| OvenWerks | You also have to make sure the lowlatency kernel is running :) uname -a will tell you | 18:25 |
| djzu | yes I made sure of that | 18:26 |
| OvenWerks | OK | 18:26 |
| djzu | If not Xfec, if not lowlatency kernel, who can be the culprit? | 18:29 |
| djzu | OvenWrks: you also said about xfce settings that might differe, can you tell more about that? | 18:32 |
| OvenWerks | setting->window manager tweaks->compositor comes to mind | 18:33 |
| OvenWerks | (though I don't htink we do different) | 18:33 |
| OvenWerks | also settings->window manager->style->theme may be different | 18:35 |
| djzu | well running Xpra from fresh Ubuntu inside virtual machine works but throw a warning about a possible bug with 'compiz'. | 18:36 |
| OvenWerks | I don't use the default theme so I don't know what it should be :) I use Moheli because I resize windows often | 18:36 |
| djzu | The error is a segmentation fault, do you think a theme can be involved? | 18:37 |
| OvenWerks | Moheli both has better indication of which window has focus (different title colour) and the frame is wider so it is easier to grab the sides. | 18:37 |
| OvenWerks | themes are quite invasive | 18:37 |
| OvenWerks | So yes a theme can do things like that | 18:38 |
| djzu | interesting | 18:38 |
| OvenWerks | A theme touches almost everything about the window. | 18:38 |
| OvenWerks | A theme has code in it | 18:39 |
| djzu | then the ubuntu studio theme could be involved | 18:39 |
| OvenWerks | So a gtk2 theme can break a wm running gtk3 | 18:39 |
| djzu | the xpra client is gtk2 | 18:40 |
| OvenWerks | I think most of the DEs (aside from KDE) are already gtk3 | 18:40 |
| OvenWerks | But quite honestly this is getting way outside anything I know about. | 18:41 |
| djzu | I switched to Moheli theme but the problem is still there | 18:44 |
| djzu | I'm afraid I'll have to forget about Ubuntu Studio and start from scratch | 18:45 |
| OvenWerks | you can start from xubuntu and install Studio meta packages to get the same Applications | 18:45 |
| OvenWerks | Don't install the ubuntustudio-desktop packages though | 18:46 |
| djzu | yes I know but that's pain since I already have a working setup for music that I'll have to screw and start over | 18:47 |
| djzu | btw, I just installed ubuntustudio-desktop packages to a fresh Xubuntu in virtual machine and still Xpra was working | 18:48 |
| OvenWerks | Is it one particular application then? | 18:49 |
| OvenWerks | Or does it crash when nothing is open too? | 18:49 |
| djzu | Xpra is an open-source multi-platform persistent remote display server and client for forwarding applications and desktop screens. It gives you remote access to individual applications or full desktops. On X11, it is also known as screen for X11: it allows you to run programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another m | 18:52 |
| djzu | it is about Xorg, X11, Xfvb, Xdummy | 18:53 |
| djzu | xpra start; xpra attach; will fail. no application involved | 18:54 |
| OvenWerks | I don't know. Maybe someone else might if when they are around. Most people are close to utc or a couple hours before utc | 19:21 |
| djzu | Thanks for your input | 19:34 |
| OvenWerks | np | 19:43 |
