| nofacetimber_ | Help please, Ubuntu Server unresponsive on boot, black screen. | 17:43 |
|---|---|---|
| nofacetimber_ | Here is some background, it's a dual boot system with windows, I just clean installed ubuntu server this morning. I was able to get in the first time without trouble. | 17:45 |
| TJ- | nofacetimber_: no need to cross-post, better off in #ubuntu for this | 17:45 |
| nofacetimber_ | Hey TJ- someone suggested here | 17:45 |
| nofacetimber_ | thanks | 17:45 |
| TJ- | yeah i know, that was before we knew it was possible kernel corruption - probably assumed you meant a video driver issue | 17:46 |
| Ussat | #1 tip, dont. dual. boot. use a VM | 17:47 |
| nofacetimber_ | TJ- so I loaded up my usb installation iso and entered rescue mode or something | 17:55 |
| TJ- | nofacetimber_: is this the LiveISO desktop, or something else? | 18:02 |
| nofacetimber_ | Well I believe its just the installation iso for ubuntu server, i'm actually reinstalling it as we speak because I can get in just fine the first time. | 18:04 |
| nofacetimber_ | Then I was going to try a reboot without messing with the wifi | 18:05 |
| nofacetimber_ | If it works then I know it's something with trying to enable wifi | 18:05 |
| TJ- | nofacetimber_: OK, that's a good solution :) | 18:05 |
| TJ- | try a few reboots to be sure then we can help you configure wifi the easy way | 18:06 |
| nofacetimber_ | Thank you TJ- | 18:07 |
| nofacetimber_ | Weird first time I reinstalled it worked again the subsequent times i'm still having trouble getting in, so i'll have to come back once I finally figure out how to get in thanks for the help TJ- | 18:51 |
| TJ- | nofacetimber_: sounds like there may be a buggy firmware on that PC, if GRUB is using biosdisk services during boot to load kernel/initrd | 18:52 |
| nofacetimber_ | just deleted all non windows partitions in an effort to reset everything to how it was when I first started, giving the install one more go :p | 19:04 |
| nofacetimber_ | You there by chance TJ-? | 20:24 |
| TJ- | nofacetimber_: I am | 20:25 |
| nofacetimber_ | I don't know, I thought I was ready because I got it to boot into ubuntu server again but then the next time I rebooted I was back to the same issues again.. So I guess its not the wifi thing.. | 20:31 |
| nofacetimber_ | Maybe i'll try another ubuntu server installation iso, any recommendations? | 20:32 |
| nofacetimber_ | I just got some error text to show up | 20:34 |
| TJ- | nofacetimber_: if it's installing but failing on reboot then something is wrong | 20:34 |
| nofacetimber_ | *ERROR* uncleared pch fifo underrun on pch transcoder A | 20:34 |
| nofacetimber_ | *ERROR* PCH transocder A FIFO underrun | 20:35 |
| TJ- | That's a hardware problem with the intel platform controller hub | 20:35 |
| nofacetimber_ | My goodness | 20:52 |
| nofacetimber_ | https://askubuntu.com/questions/887557/ubuntu-16-10-booting-in-emergency-mode-after-upgrade-from-16-04 | 20:52 |
| nofacetimber_ | Finally found a solution | 20:52 |
| nofacetimber_ | whew.. Must be something weird with the dell computer but setting the vt_handoff to 0 and I have sucessfully rebooted a couple times. | 20:53 |
| nofacetimber_ | TJ- I would appreciate your help with that easy wifi setup you mentioned :) | 20:54 |
| TJ- | oh, so a video issue, the PCH bug causing the DRM video driver to fail, so disabling mode-setting works around it | 20:54 |
| nofacetimber_ | Ahh yeah guess so | 20:54 |
| TJ- | nofacetimber_: does "nmcli" report status ? | 20:54 |
| nofacetimber_ | installing network manager right now | 20:55 |
| nofacetimber_ | will give it a try | 20:55 |
| TJ- | OK, once it's installed use the ncurses console connection configuration tool to configure it just as you would from the GUI desktop, using "nmtui" | 20:56 |
| TJ- | Tab key moves between fields and buttons | 20:56 |
| nofacetimber_ | i'm very new to ubuntu so some of that went over my head but i'll give it a go | 20:57 |
| TJ- | nofacetimber_: OK, quick background. NetworkManager is a system service so is fine on a server. but many Linux GUI desktop users only interact with it through a taskbar icon called nm-applet and thus assume NM is GUI-only. But in a console the "nmtui" tool can do the same job as nm-applet's connection editor does in a GUI | 20:58 |
| nofacetimber_ | ahh cool | 20:58 |
| TJ- | nmtui == network-manager TEXT user interface | 20:58 |
| TJ- | so you can configure the Wifi there and it'll sort out wpa_supplicant, dhclient and everything else | 20:59 |
| nofacetimber_ | Thank you | 21:00 |
| TJ- | mak sure you configure the connection for "all users" and "start automatically" | 21:00 |
| nofacetimber_ | NetworkManager is not running | 21:00 |
| TJ- | "sudo systemctl start network-manager" | 21:00 |
| nofacetimber_ | Thanks so I think i'm connected I just entered the password without any errors, i'm still in the user interface | 21:02 |
| nofacetimber_ | now about configuring the connection for all users and start automatically | 21:02 |
| nofacetimber_ | do I exit out of the user interface now? | 21:02 |
| TJ- | you tab to the Close/Quit 'buttons' and press Enter on them to exit cleanly | 21:03 |
| nofacetimber_ | done | 21:03 |
| nofacetimber_ | So i'm exactly sure about the "start automatically" and "all users" part? | 21:04 |
| TJ- | have you added "nomodset" permanently to the boot option?s | 21:04 |
| nofacetimber_ | I don't think so, the only thing I changed permanently was the vt_handoff | 21:05 |
| nofacetimber_ | but I can reboot and double check | 21:05 |
| TJ- | nofacetimber_: in 'nmtui' when you're doing "edit connection" at the bottom of the panel are [x] Automatically Connect and [x] Available to all users - make sure they are both checked | 21:05 |
| TJ- | ok, so we need to set "nomodeset" permanently... hang on a mo ... | 21:06 |
| nofacetimber_ | Sweet yes they are checked. | 21:06 |
| TJ- | OK, and finally do "sudo sed -i 's/\(GRUB_CMDLINE_LINUX="\)/\1nomodeset /' /etc/default/grub " | 21:08 |
| nofacetimber_ | Why is that needed? Just curious | 21:08 |
| TJ- | then "grep nomodeset /etc/default/grub" to check it was added, if so, do "sudo update-grub" which updates GRUB's /boot/grub/grub.cfg so 'nomodeset' is used at boot time | 21:09 |
| TJ- | /etc/default/grub uses shel variables that "update-grub" takes to write the actual GRUB config file /boot/grub/grub.cfg | 21:09 |
| nofacetimber_ | Oddly enough nomodeset caused me boot issues again, nomodeset is for graphics right? | 21:18 |
| TJ- | it's for stopping the kernel doing mode-setting of the GPU. | 21:18 |
| nofacetimber_ | hmm | 21:18 |
| nofacetimber_ | I don't have a dedicated GPU maybe that's why | 21:19 |
| TJ- | makes no difference, there's a GPU there and KMS is standard but due to that hardwre PCH bug it's causing issues. Can you reboot into the OS ? | 21:20 |
| TJ- | is it 16.04 Xenial LTS you've installed? | 21:20 |
| nofacetimber_ | Pretty sure it's just ubuntu server 16.04. So if I remove nomodeset I see the ubuntu splash screen loading | 21:31 |
| nofacetimber_ | it sits there for a long time, if I hit a key then I see some text. | 21:32 |
| TJ- | nofacetimber_: you can upgrade it to the latest kernel which may solve the PCH bug. "sudo apt install linux-image-generic-hwe-16.04" | 21:32 |
| nofacetimber_ | A start job is running for Raise network interfaces | 21:32 |
| TJ- | hwe == HardWare Enablement | 21:32 |
| nofacetimber_ | looks like i need to wait about 5 minutes.. | 21:32 |
| nofacetimber_ | okay i'll try that | 21:33 |
| TJ- | hmmm, that shouldn't happen if NM is setting up the wifi as a system connection | 21:33 |
| nofacetimber_ | well once i'm in i'll see if I can do that upgrade without a wired connection.. | 21:33 |
| nofacetimber_ | tdowdle | 21:35 |
| nofacetimber_ | *sorry wrong keyboard | 21:35 |
| nofacetimber_ | getting the latest kernal now | 21:37 |
| nofacetimber_ | and doing it on wifi | 21:37 |
| nofacetimber_ | so the wifi seemed to be working once I got in.. | 21:37 |
| TJ- | we may need to check why the start-up delayed once you've got the new kernel installed and rebooted into it | 21:38 |
| nofacetimber_ | okay it finished | 21:38 |
| nofacetimber_ | Appreciate all the help by the way | 21:38 |
| nofacetimber_ | want me to do a debug reboot? | 21:39 |
| TJ- | try regular for now, no point debugging unless there's an issue! | 21:40 |
| nofacetimber_ | hmm | 21:41 |
| nofacetimber_ | okay so I just tried a regular reboot | 21:41 |
| nofacetimber_ | I didn't see the splash screen it was just sitting there all black with a white underscore in the top _ | 21:41 |
| nofacetimber_ | I waited for about 30 seconds then decided to hook up a direct connection | 21:42 |
| nofacetimber_ | eventually I got to the login prompt | 21:42 |
| nofacetimber_ | about 20 seconds later | 21:42 |
| nofacetimber_ | or less | 21:42 |
| TJ- | sounds like you need to disable graphical boot | 21:42 |
| nofacetimber_ | so I'm thinking it might of been that same Raise network interfaces thing I just couldn't see it | 21:42 |
| TJ- | lets' get rid of the splash screen. Are you comfortable using a terminal text editor? | 21:43 |
| nofacetimber_ | yeah somewhat confortable | 21:43 |
| TJ- | Do you know/prefer nano or vim ? | 21:44 |
| nofacetimber_ | nano works | 21:44 |
| TJ- | OK, "sudo nano /etc/default/grub" | 21:44 |
| nofacetimber_ | done | 21:44 |
| TJ- | goto the line "#GRUB_TERMINAL=console" and delete the # (comment) then save the file and do "sudo update-grub" | 21:45 |
| TJ- | that'll tell GRUB to stay in VGA text mode | 21:45 |
| nofacetimber_ | okay | 21:46 |
| nofacetimber_ | try a reboot? | 21:47 |
| TJ- | yes | 21:47 |
| nofacetimber_ | okay i'm in and everything seemed to load fast. That said i'm still on wired connection whoops | 21:49 |
| TJ- | hehehe | 21:49 |
| nofacetimber_ | Yeah If I don't connect wired then I get that 5 minute delay | 21:52 |
| TJ- | OK, that suggests the system is trying to connect on wired too, which could be down to systemd-networkd - it generally is! | 21:54 |
| TJ- | so, once it's got to login do "sudo apt install pastebinit" then "pastebinit <( systemd-analyze blame )" and give me the URL | 21:55 |
| TJ- | because it's already 'seen' and used the wired it expects to find it and sits around waiting | 21:56 |
| nofacetimber_ | makes sense | 21:57 |
| TJ- | you should be able to check and disable it with "systemctl status systemd-networkd" should show "Loaded: loaded (/lib/systemd/system/systemd-networkd.service; disabled; vendor preset: enabled)" --- notice the "disabled;" ... if that says "enabled" do "sudo systemctl disable systemd-networkd" | 21:58 |
| TJ- | then at next boot it /should/ be OK | 21:59 |
| nofacetimber_ | Okay sorry i'm having trouble with the pastebinit command, failed to contact the server Temporary failure in name solution. But i'll try the other | 22:03 |
| nofacetimber_ | i'm pining just fine on wifi | 22:03 |
| nofacetimber_ | pinging | 22:03 |
| TJ- | hmmm, that suggests DNS may not be working, is the wifi configured for using DHCP? | 22:04 |
| nofacetimber_ | In those settings everything looks as you said, so maybe there is something wrong with the wifi, I seem to be able to download things with sudo apt-get just fine. | 22:11 |
| TJ- | nofacetimber_: hmmm, and that needs DNS so not likely to be that | 22:12 |
| TJ- | Try " dig +short paste.ubuntu.com" | 22:12 |
| nofacetimber_ | Well I guess I can live with that if I have to lol | 22:12 |
| nofacetimber_ | okay | 22:12 |
| nofacetimber_ | timed out no servers could be reached so must be something on my end.. I'll troubleshoot it a bit | 22:15 |
| nofacetimber_ | Appreciate the help TJ- I'm a lot further along then I was before, will take a break and work on it some more later. Have a good evening! | 22:41 |
