How to use on debian?

[kopax]

I have downloaded debian and bought a new desktop computer.

I tried the plugin and the screen is available in Display. However, I can't make it work, if it's enabled, then all the desktop get frozen, even if the screen is on and I can't move my mouse inside.

Why?

Thanks in advance

[AdnanHodzic]

@kopax what happens if you mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf and restart X (log out and log in).

Also which version of Debian are using?

[kopax]

Thanks for the quick reply @AdnanHodzic I appreciate.

I am using this version of Debian:

Linux dev-12 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u6 (2018-10-08) x86_64 GNU/Linux

I will redo the test once I am done working on this computer.

@AdnanHodzic, thanks for doing this module. I only use Debian and for about 3 years I was not able to use that MB168+ screen. An old version of this project used to work with Debian but that wasn't stable. After doing a Linux kernel update on my laptop (required by latest docker daemon for storage v2 driver), it stopped completely to work.

I expected to use a default Debian install would be working fine but it is not.
I would gladly contribute to testing if you can help me get this screen working in a reliable way, I don't have any knowledge with xrandr, I am web developer.

[kopax]

I have just followed your recommendation

dka@dev-12:[~]: xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:Intel
Provider 1: id: 0x18a cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting
dka@dev-12:[~]: sudo mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf
dka@dev-12:[~]: cat /tmp/20-displaylink.conf
Section "Device"
  Identifier  "Intel"
  Driver      "intel"
EndSection

After log out and log in, I am doing

dka@dev-12:[~]: xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:Intel
Provider 1: id: 0x18a cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting
dka@dev-12:[~]: xrandr --setprovideroutputsource 1 0

On cinnamon, if I go in Display and activate my display, the screen turn on, I can see the background, I can see windows from another screen, I can move my mouse, but I can't bring window into that screen. It is like if the desktop environment is frozen.

By doing mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf, I am not crashing my configuration, but it is not working better.

$ uname -a
Linux dev-12 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u6 (2018-10-08) x86_64 GNU/Linux

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 9.5 (stretch)

Codename:	stretch

It seems to be close to work, do you know how I can fix this @AdnanHodzic ?

[AdnanHodzic]

@kopax ok forget about removing mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf.

Every time you upgrade a new kernel you need to re-install, so could you please run "uninstall" and then reboot the computer and then do "reinstall". It seems like your displays are recognized just fine from what I see here.

[kopax]

Every time you upgrade a new kernel you need to re-install

As I said, I have one Lenovo X1Carbon Gen 1, I have updated the kernel once and since I am not able to use the screen, even with reunstalling, formating etc... I have no clue why, I am juste reporting.

It seems like your displays are recognized just fine from what I see here.

Yes it is, but again, that's a desktop brand new computer. I did not upgrade the kernel or do any things with the core of linux since I installed it. Using that fresh install, the driver does not make it work and I have a freeze effect. I think this is the most common setup people will have.

[AdnanHodzic]

@kopax did you pull latest changes (as of today), and run reinstall?

[kopax]

You mean this one ? https://github.com/AdnanHodzic/displaylink-debian/pull/175/files

Basically, that's the revert of what you already asked me to do before with mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf.

I can pull but looking at the operation, you have not changed anything so there is no reason to see it working. Do you want me to still do it, film me and post it on youtube? Maybe that would help see you how the screen freeze.

[AdnanHodzic]

Sorry, I got mixed up with a different issue I saw your name in.

Let's start from the beginning, can you please verify that you went through post installation guide?

To be 100% if possible I would like if you could "Uninstall" the driver reboot, run "Install" again reboot and see if you still have the same problem.

Please paste output of whole "Install" process here.

[kopax]

Let's start from the beginning, can you please verify that you went through post installation guide?

Yes I did a few times.

To be 100% if possible I would like if you could "Uninstall" the driver reboot, run "Install" again reboot and see if you still have the same problem.

1. Sure, I've updated my branch:

From github.com:AdnanHodzic/displaylink-debian
   a236153..56b72e6  master     -> origin/master

1. I've stopped the dlm.service with systemctl stop dlm.service.
2. Run the script as root and choose Uninstall, I got Uninstall complete message
3. Reboot
4. Run the script as root and choose Install (log below)

Note that:

• Doing mv /etc/X11/xorg.conf.d/20-displaylink.conf /tmp/20-displaylink.conf permit the screen to display but not to respond.
• Upgrading to latest master show a black screen.

Is the conf file wrong for my computer?

[AdnanHodzic]

1. I remember your graphics card was i915. Because if you look at latest master: https://github.com/AdnanHodzic/displaylink-debian/blob/master/displaylink-debian.sh#L304

Your /etc/X11/xorg.conf.d/20-displaylink.conf file should contain following:

Section "Device"
  Identifier  "Intel"
  Driver      "intel"
EndSection

Can you confirm this is the case? If it is, what results do you get with this being as part of 20-displaylink.conf?

2. What were the contents of /etc/X11/xorg.conf.d/20-displaylink.conf in that Youtube video?

3. Are changes better or worse with latest changes from master?

[kopax]

It appear that I was not having this file.

root@dev-12:/home/dka# cat /etc/X11/xorg.conf.d/20-displaylink.conf
Section "Device"
  Identifier  "DisplayLink"
  Driver      "modesetting"
  Option      "PageFlip" "false"
EndSection

Using your version, I am able to use my screen. I hope it will be stable. Thanks a lot for supporting the display link driver on Debian. I've just saved 100$. Thanks a lot and keep up with the good work.
