Problems in Ubuntu 17.04

Hi,

I have upgraded to Ubuntu 17.04 and DisplayLink is not working properly (or Ubuntu :)). Now the external monitor can be seen but it is frozen. It was working perfectly with Ubuntu 16.10 and Ubuntu 16.04.

Thanks in advance,
Carlos

I also have the same problem

Ubuntu 17.04 , Gnome 3.24, latest drivers

the external screen is freezed on the first frame that's drawn (99% of the time it is a black screen with only the mouse pointer)

After updating to Ubuntu Gnome 17.04 from Ubuntu 16.04, I experience the same issue as described above:

The DisplayLink installer works fine, and a monitor connected through my DisplayLink Docking Station is recognized and can be activated. However, the image on the monitor is not refreshed. It generally stays black, or shows a frozen image. The mouse cursors is the only thing that is visible and active on the monitor.

To check whether this issue might be due to Gnome Shell, I also tried it with Xfce4, which uses simple non-hardware accelerated graphics. But the problem is the same with Xfce4.

On Ubuntu 16.04, things worked like a charm (except for excessive CPU use).

I attached the output of the Linux Support Tool.

I'm getting the same with my installation of Ubuntu 17.04. Has anyone managed to get anywhere with this? At the moment my two external monitors are completely useless and I'm having to use my laptop's in-built screen all the time.

For Intel Graphic Drivers
 
If you are using a Intel Graphic chip (I have a notebook with dual chip Nvidia/Intel), you can use this configuration:

edit /etc/X11/xorg.conf.d/20-intel.conf (Most users do not have that folder xorg.conf.d, so just create it and the file 20-intel.conf :

add this to the file:
Quote:

Section "Device"
Identifier "Intel Graphics"
Driver "Intel"
Option "AccelMethod" "sna"
Option "TearFree" "false"
Option "TripleBuffer" "true"
Option "MigrationHeuristic" "greedy"
Option "Tiling" "true"
Option "Pageflip" "true"
Option "ExaNoComposite" "false"
Option "Tiling" "true"
Option "Pageflip" "true"
EndSection
Save and reboot PC:
This worked for me, only, that my courser flashes a bit when I have high CPU load. I don't know the reason for that.

Hope that helps. Much luck.

PS: I tried that with Ubuntu Gnome and Ubuntu Mate, both worked.

Thanks He'emin. I had the same, frozen screens. Your solution works like a charm for me. High CPU usage with this, however it works ;-).

My config:
- Fedora 26
- kernel 4.11.0-0.rc8.git0.1.fc26.x86_64
- evdi module 1.40

Thanks again!

Same issue on Kubuntu 17.04. Tried He'emin's solution. Not sure if it works, now I can't enable the second USB display at all.

Graphics:
VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

This has worked for me too, thanks. I'm not sure what each part of the config does, but I'm going to have a read and see if changing any bits make any difference to my particular set-up.

I notice that there are two sets of options that have been repeated (specifically tiling and pageflip)---is this intentional?

Edit:

I deleted all of the `Option` lines from the config file, and rebooted. Everything still worked! It appears that many of those are the default values, so just the presence of the file appears to set them. I also found that I was only able to see the Ubuntu login screen on the main laptop screen, but then added a file at `/etc/X11/xorg.conf.d/20-radeon.conf` (the other card in my laptop is an AMD/ATI) with settings:

Quote:

Section "Device"
Identifier "Radeon"
Driver "radeon"
EndSection
which seems to do something as the login screen now appears on my two external monitors too. I'm not sure why this worked for me, but it appears to have done something!

No, it was not intentional. I just gathered information from different posts at it worked. It is not that I totally understand this whole config thing :rolleyes:

After many trials...
installed fresh ubuntu 1704 with unity because gnome did not work for me and installed ubuntu Feb 2017 newest displaylink-driver-1.3.52.
Screen was recognized in display settings though blank however mouse would navigate over but could not be seen.

Used troubleshooting on this page xrandr to set DVI screen refresh parameters not sure if this was really necessary but did it any way >>> https://wiki.archlinux.org/index.php/DisplayLink
but still had issues till>>>

Adding /etc/X11/xorg,conf.d/20-intel.conf and rebooted.
So many thanks is due to you.

My laptop is M11X Alienware i3
