USB2VGA SIS or Displaylink DL-165

k.king · 12-01-2019, 06:55 AM

I'm trying to get some USB to VGA adapters working with Mint LMDE2 or pure Debian 9 (LXDE) units.

I have two that I believe are SIS based chips and one that is Displaylink DL-165 based.

When I plug one of the SIS into the unit I get a red border around a black screen, the other SIS one the same although it has alternating black and white horizontal stripes.
The displaylink one gets a green screen.

Most answers I can find say this is all fine and then make changes to the xorg.conf.d file .... but I do not have one of those, so where should should the changes go now?

xorg.conf.d/ is an optional directory, for overriding defaults if necessary. If you need one, make one.

below is xorg.conf file I tried, generated out of Xorg -configure and with detail added for an MCT/SIS based adapter adapter. I tried placing this in the following
/etc/X11/ /usr/share/X11 and withing the xorg.conf.d folder within those one at time by themselves (i.e. only present in the one location) nothing made any perceptible difference ...
nothing seems to show up in logs... though there is no Xorg.0.log being generate like had on older distro's ?

Code:

$xrandr --listproviders     
     just lists the one provider always present
$ xrandr --listmonitors
Monitors: 2
 0: +*LVDS1 1366/340x768/190+0+0  LVDS1
 1: +HDMI1 1920/620x1080/340+0+0  HDMI1

$xrandr -q
  has same content as before though it has one more line 
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

Did you look for an Xorg.n.log in both ~/.local/share/xorg/ and /var/log/?

Make your attempt to build xorg.conf easier by not manually configuring unnecessarily: leave out all the input and files sections, adding them back only if necessary if and when you get some video with non-working input from your dongl

What does simply xrandr output while attemmpting to use the usb donngle?

btw would KVM disable by BIOS affect any of this?

Oops!

Code:

sudo apt install xserver-xorg-video-modesetting

But, according to inxi, it seems to be installed already.

This is peculiar output. If

Code:

inxi -V

shows version 2.4.x, please get and use the upstream inxi version.

mrmazda · 12-08-2019, 02:00 PM

I've never tried any USB-to-VGA adapter. Next I would try purging xserver-xorg-video-intel, to see if the modesetting driver can overcome the deficiencies reported by Xorg.0.log. If not, next I would try changing the BIOS GPU priority, if that's possible, or disabling the onboard GPU, if possible. Older onboard Intel GPUs tend to be either/or, not compatible with simultaneous use of another GPU. I would do all this first without any xorg.conf file, and add manual configuration only as a last resort if nothing else helps.

Do not disturb the content of /usr/share/X11/. That's the exclusive domain of the package management system. Manual configuration belongs in /etc/X11/, for overriding automagic, if necessary.

inxi can update itself via its -U switch if you create /etc/inxi.conf or add to or change it to include B_ALLOW_UPDATE=true. IIRC on Debian it already exists and needs to be changed.

In terms of the corrupted drivers, you have to take the /var/log/Xorg.0.log file and paste it at the same time that inxi shows the -G driver errors. That is, run inxi, see if it shows the excess drivers, and if it does, immediately pastebin the full /var/log/Xorg.0.log file

The file linked to here was not the same file that triggers this error because it doesn't have that error in it.

This is a very easy item to debug because the output MUST show whatever the Xorg.0.log file had in it, so all I have to do is run the datasource as the test file and it will reproduce the error, it has to.

Note that I don't believe inxi supports USB vga adapters, I think I was thinking about doing it, but I didn't have any data for it, and it didn't seem like I ever found anyone who actually used one. But the drivers list doesn't come from usb data, it comes from the xorg log file.
