| pchoo | Hi, Anyone able to help me diagnose an issue I'm having? I'm on 16.04.1, and recently did a dist-upgrade (a few weeks ago). Since then when I log out or try to shut down, I end up with a blank screen which has an underscore in the top left, and I am unable to change TTY or interact in any way, the only thing I can do is hold the power button and reboot. | 11:25 |
|---|---|---|
| pchoo | I have since done another dist-upgrade to see if that resolves the issue, but I am not too familiar with trouble shooting linux | 11:25 |
| mgedmin | how long have you waited? | 11:34 |
| pchoo | I've left it for about 20 minutes before | 11:38 |
| pchoo | lately I've had less patience as I usually shut down before I have to leave work | 11:38 |
| pchoo | it only started after I ran dist-upgrade a short while ago. I intend to do a fresh install with 16.10 at some point, but was going to wait until closer to christmas where we have some down time | 11:39 |
| pchoo | the only issues I can see on google are to do with booting up, and not with shutting down or logging out. | 11:40 |
| pchoo | mgedmin: If you've got any advice on what I can look at, or how I can help diagnose what is going on, or any requests for information, please let me know | 11:41 |
| mgedmin | ok, 20 minutes is overkill | 11:41 |
| mgedmin | altough... in 16.04 I had poweroffs/reboots taking 15-20 minutes with a black screen | 11:42 |
| mgedmin | turned out it was swapoff taking this much time | 11:42 |
| mgedmin | if I opened a terminal and did a 'sudo swapoff -a' before initiating the reboot, then I had to wait maybe 15 minutes for swapoff to do its job, and then the reboot was fast | 11:42 |
| pchoo | How can I check to see if that's what is causing the issue for me? | 11:43 |
| pchoo | just try running that in a terminal and see if I can do reboot after? | 11:43 |
| pchoo | I am using a laptop with optimus, however I am using the intel drivers only right now (I believe) | 11:43 |
| mgedmin | the way I diagnosed the issue was adding a bunch of debug prints to my init.d scripts (it was before 16.04 and systemd) | 11:43 |
| mgedmin | with 16.04 there's now /usr/share/doc/systemd/README.Debian.gz that tells you how to diagnose shutdown issues | 11:44 |
| mgedmin | but I suggest trying a manual sudo swapoff -a before you reboot, to see if it's maybe the same issue | 11:44 |
| mgedmin | alternatively, before you reboot, check how much swap is in use | 11:44 |
| pchoo | Ok, thank you, I'll have a quick look at the document, then give that a try | 11:45 |
| pchoo | ok | 11:45 |
| mgedmin | if nearly 0, no need to try this, it's a different issue | 11:45 |
| mgedmin | I used to have ~4 gigs of swap in use | 11:45 |
| pchoo | KiB Swap: 16658428 total, 16658428 free, 0 used. 13500772 avail Mem | 11:45 |
| pchoo | That's the line from top | 11:45 |
| mgedmin | there goes my guess | 11:46 |
| pchoo | mgedmin: thanks for trying. I'll have a look at the debug shell | 11:48 |
| pchoo | mgedmin: well, that didn't work, or rather, I could enter the shell before I tried shutting down, but not after I got the screen with the underscore, and there was no keyboard response from the usb keyboard, nor the laptop keyboard | 11:53 |
| mgedmin | :( | 11:54 |
| pchoo | Any other suggestions? Thank you for your help so far | 11:57 |
