Debian SID : Fail to connect screens #130

Closed odivel closed 5 years ago

odivel commented 6 years ago

Hi,

This morning I had an issue when trying to connect my displaylink device. When I activate my screens it brings back to the login screen.

I thought it was kernel related (this weekend I updated to 4.16) so I reverted back to 4.15.0.3 and reinstalled the displaylink driver but I have the same issue.

Can you help me with this ?

Regards, ODI

AdnanHodzic commented 6 years ago

Are you logging into X11 session? WIth Sid/Booster Wayland has been set to be default, and Displaylink doesn't work on Wayland ATM.

odivel commented 6 years ago

Hi,

I'm aware of that and I'm logging into X11 session (choose Gnome on Xorg when logging) It was working fine until today.

The only thing I've done is an aptitude upgrade, kernel was updated to 4.16 but I have the same issue with 4.15.

odivel commented 6 years ago

to add more informations

dlm.service is started

xrandr --listproviders Providers: number : 3 Provider 0: id: 0xb6 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 0 name:modesetting Provider 1: id: 0x81 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 1 outputs: 1 associated providers: 0 name:modesetting Provider 2: id: 0x41 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

And you will find in attachment a dmesg

dmesg.txt

AdnanHodzic commented 6 years ago

What happens if you temporarily remove this file: /usr/share/X11/xorg.conf.d/20-displaylink.conf and reboot?

If doesn't do anything, could you please add nomodset parameter to your kernel and see if that works?

odivel commented 6 years ago

Ok so I tried to remove /usr/share/X11/xorg.conf.d/20-displaylink.conf but it does nothing

And when adding nomodset nothing too (tried with nomodeset and it's not booting)

Here is what I added : GRUB_CMDLINE_LINUX_DEFAULT="elevator=deadline radeon.modeset=0 modprobe.blacklist=radeon nomodeset quiet"

Maybe I've done something wrong ?

I tried with Kernel 4.16, should I retry with 4.15 ?

AdnanHodzic commented 6 years ago

So after adding nomodeset it's still not working? Also why did you add rest of the parameters, i.e:

elevator=deadline radeon.modeset=0 modprobe.blacklist=radeon?

odivel commented 6 years ago

After adding nomodeset it's not booting at all, I have a black screen and nothing (have to boot in recovery mode to remove nomodeset)

I added elevator=deadline to change the I/O scheduler, and radeon.modeset=0 modprobe.blacklist=radeon is a workaround to solve a vce init error radeon 0000:08:00.0: failed VCE resume (-110) Just tried without these options and with Kernel 4.15 in case of but same issue.

odivel commented 6 years ago

If I cannot solve this issue I think I will just migrate to Ubuntu for my professional Laptop

Too much issues like that with Debian SID, maybe I've underestimated the unstability of Debian Unstable (Yeah I know many people would say that they never had problems for years)

AdnanHodzic commented 6 years ago

I'm really not sure what the problem is here.

It definitely takes a lot of dedication to use Debian Sid as your work laptop. I would recommend using Testing/Buster, or even if Stable/Stretch with APT pinning.

I wrote about this topic few years ago in case you decide to go down this path: Taking control over Debian and its package repositories

Either way, let me know if you end up having same issue with whatever out of these you decide to go with. Similiar problem was reported on Ubuntu 18.04 yesterday but was resolved with nomodset

odivel commented 6 years ago

Ok I think I will make a try with Ubuntu 18.04 and report if it work well

Thanks for your time

odivel commented 6 years ago

Ok so I moved to Ubuntu 18.04 and it's working fine

For now I will keep Ubuntu and switch to Debian later

AdnanHodzic commented 6 years ago

Great, also out of curiosity did you have to make any customizations. Or displaylink-debian install got everything working out of box?

odivel commented 6 years ago

It worked out of the box,

But I think I will go back to Debian, I will try testing with apt pining

cilynx commented 6 years ago

I can second the issue, but I haven't figured out the cause yet. I've been successfully running a pair of displaylink adapters under Sid with 4.16 for a while and all of a sudden today while doing nothing out of the ordinary my session crashed and it kicked me out to the login screen. I haven't run an aptitude update in several days. When I logged back in and went through the normal dance, I can set things up through xrandr fine, but once I enable either display in gnome-control-center, it kicks me back out to the login screen. I'll post back if I can figure out what's going on.

redjamesg commented 6 years ago

I too noticed this, using the latest install script, the only temporary solution I have found is to remove the /use/share/X11/xorg.config.d/20-xorg.displaylink.conf file and keep my old one that I made along with the very first install of this driver.

cilynx commented 6 years ago

I managed to get back up and running by sudo apt purge gnome* xorg*, reconfiguring networking from the cli, swapping unstable to testing in my sources.list then sudo apt install gnome xorg. I'm still running the newest 4.16, so the breaking change must have come from an update in xorg. I'm guessing my "random" crash came from whatever part of xorg got updated with the breaking change finally being reloaded from disk on my machine.

@redjamesg -- can you share your 20-xorg.displaylink.conf that is working for you in sid? If I can spare another couple hours to trash my machine again tomorrow, I'd like to try it out.

odivel commented 6 years ago

Hi,

Ok so I decided to reinstall Debian testing and it's working fine.

I'm using apt pining for some softwares but displaylink is working with the last script

Maybe a broken xorg that have been fixed

redjamesg commented 6 years ago

This is my current xorg.conf

Section "Device" Identifier "Intel" Driver "intel" Option "VSync" "false" EndSection

AdnanHodzic commented 6 years ago

@redjamesg what happens for you if you add Option "VSync" "false" to /usr/share/X11/xorg.conf.d/20-displaylink.conf file?

Would love to extend it so we could potentially have an universal file which we could use everywhere.

redjamesg commented 6 years ago

What I was experiencing, was after installing with teh latest script my three monitors were working as expected without any issues, but two days later they startet acting up. Occationaly they would flicker and drop me to the login prompt of my GUI (xfce) once again but after a few activations they would continue to work. This tendency would increase in frequence and at one point I was unable to activate the monitors, they would get stuck in the state described in #68 and since I remembered my fix for that I tried to change the 20-displaylink.conf file to just being what I used then, and now everything works.

I will on a later instance try the "VSync" "False" setting in the orriginal 20-displayling.conf to verify if that has an impact on my issues.

redjamesg commented 6 years ago

OK, it turns out I have to use the 

Driver "Intel"
Option "VSync" "false"

settings in the 20-displaylink.conf file else my monitors wont be correct activated and I will end up with the described freezing/black/grey screens described in #68

My setup is Dell XPS13 9360 with a Toshiba Dynadoc U3 PA3729E-1PRP displaylink and three monitors. Running Debian Stretch with displaylink 4.2 for Ubuntu.

Had a similar problem when using this on Debian Testing few months ago. I followed the advices in #68. My xrandr didn’t show any providers (as described in the Arch Forum). The monitor worked, after I disabled the Wayland backend in GDM (see Arch Wiki, GDM “Use Xorg backend”).

Edit: Just realized that my comment doesn’t help with this issue. I’m really sorry for posting this.

But I experience the same issue with Debian Testing (kernel version 4.17.0 and Xorg 1.20). Using Option "VSync" "false" didn’t resolve the issue and using Driver "Intel" instead modesetting caused the xrandr Provider to disappear.
