| alkisg | Hi, in Ubuntu 18.04, several schools reported having black screen with i915 after recent updates. With a quick look, I couldn't pinpoint anything, and booting with an older kernel didn't fix the issue. Has anyone reported this? | 11:31 |
|---|---|---|
| alkisg | systemctl --failed shows gpu-manager and lightdm as failed; but Xorg.0.log doesn't show any errors. | 11:32 |
| ricotz | alkisg, maybe the mesa hwe update? | 11:37 |
| ricotz | (and libdrm) | 11:37 |
| tjaalton | kernel | 11:39 |
| tjaalton | 4.15.0-44 was buggy | 11:39 |
| alkisg | ricotz: all my schools are using 18.04.1 fully updated, which means no hwe stack, | 11:40 |
| alkisg | tjaalton: they have the issue with -45 as well | 11:41 |
| ricotz | alkisg, mesa 18.2.2-0ubuntu1~18.04.1 is basically an hwe update | 11:41 |
| alkisg | Ah, that goes to people without the hwe stack too? That might be it, then | 11:42 |
| alkisg | I even tried with 4.15.0.20.23 and it didn't make any difference | 11:42 |
| ricotz | yes, together with libdrm | 11:42 |

| ubottu | Launchpad bug 1798597 in xserver-xorg-video-vmware-hwe-18.04 (Ubuntu Bionic) "Backport packages for 18.04.2 HWE stack" [Undecided,Fix released] | 11:43 |
| alkisg | Nomodeset did seem to workaround the problem; I'm not sure what this does to i915-based cards | 11:43 |
| tjaalton | disables everythign | 11:43 |
| tjaalton | doesn't even load i915 | 11:43 |
| tjaalton | try 18.2.8 from the x-updates ppa | 11:43 |
| alkisg | Thank you, will do tomorrow, when I'll be able to contact one of those schools again | 11:44 |

| tjaalton | it's on the sru queue | 11:44 |
| tjaalton | as well | 11:44 |
| ricotz | alkisg, may I ask which intel gpu fails? | 11:44 |
| alkisg | Let me see if I kept the model in the irc chat... | 11:45 |
| * ricotz didn't update ltsp systems to bionic yet, but is planning to | 11:45 | |
| alkisg | From? 16.04? | 11:46 |
| alkisg | 18.04 is much more stable than 16.04, if you use the greek schools ppa | 11:46 |
| ricotz | yes, currently on xenial | 11:46 |
| alkisg | I think this was the xorg log, booted with nomodeset: https://termbin.com/vz2e | 11:46 |
| alkisg | srv-6gym-chalk, yes, that was the one | 11:46 |
| tjaalton | doesn't show anything | 11:47 |
| alkisg | Ugh yeah nomodeset hides the model :( | 11:48 |
| tjaalton | about the hw | 11:48 |
| tjaalton | lspci would | 11:48 |
