Here are the details:

First the monitor is this monitor is the ASUS MB168B 15.6" HD Portable USB-Powered Monitor

I'm not sure if I need a different driver, or what I can do to fix this, any insight?

Much appreciated, thank you.

I found info that it use USB
Then I found this - other hardware https://www.youtube.com/watch?v=JJua1bBIl6g
And he used driver from from the manufacturer's website for his own hardware.
I found something like that https://www.asus.com/supportonly/MB168B ... _download/
And I see there drivers for Linux.

Why this drivers are not inside Linux Kernel ?
In kernel I not found about MB168B --> nothing https://github.com/torvalds/linux/search?q=MB168B
In kernel bugzilla also I not found --> nothing https://bugzilla.kernel.org/buglist.cgi ... =%20MB168B
I don't know this why. You can ask your own hardware manufacturer. ( asus.com )

ok thankyou, I installed that driver from asus and now the screen is detected, however it looks all wonky. Here is a picture of what the external monitor looks like:

although my computer doesnt know it looks like that because if I press print screen it shows this:

https://postimg.cc/2VrfYsVn/7098576a

the left half of the picture is the external monitor that is appearing all wonky.

I installed that driver from asus and now the screen is detected, however it looks all wonky.

Perhaps that might be related to the cable you are using? Make sure the cable is securely attached at both ends. You may also want to try a different cable.

[minty_tea]

it turned out I was able to fix it by lowering the resolution on it from 1366x768 to 1024x768.

That's 90% satisfying.

I'm just wondering if there is a way to run it at its full resolution of 1366x768 (which is its full resolution according to amazon) and the randr command.

I'm just wondering if there is a way to run it at its full resolution of 1366x768 (which is its full resolution according to amazon) and the randr command.

Please supply the output of xrandr --verbose. That should let us know what Mint is picking up as its capabilities.

ok here is that output of xrandr --verbose:

although my computer doesnt know it looks like that because if I press print screen it shows this:

https://postimg.cc/2VrfYsVn/7098576a

Did you try changing the refresh rate when you had the 1366x768 resolution? It should be ~60Hz per the xrandr output, but the 1024x768 should be ~75Hz per xrandr. Is the latter what you have when you get an image onscreen?

The 1366x768 is picked up as the preferred resolution with the 1024x768 as the current.

I found this thread USB Monitor/Display link issue where the person was mentioning the same type of issue with that monitor, but on Windows 10. The person does mention the DisplayLink driver was automatically downloaded for Win10.

There is a DisplayLink driver for Linux-based distros, however, people have had to use some modifications to get it to work properly. I do not know if the driver you downloaded from ASUS is a DisplayLink one, but I assume it probably is.

At this point, I'm not sure if this is a driver issue or if it is a cable issue. Usually, if the DisplayLink driver does not work, there is no image, but that is not the case in this situation.

Let us know if changing the refresh rate gives you an image with 1366x768. If you have another cable, I suggest trying it to see if there is a difference.

If not, here is DisplayLink information in a post from someone whose manufacturer did not have a driver for them to download so they used the publicly available DisplayLink driver with some patches.

The refresh rate of 60 was already the one provided using the display gui tool, so yes I did use that. I have now attempted switching also to 75.00 and 75.03 using the command line at the higher resolution and that didnt work.

I did

xrandr --output DVI-I-1-1 --mode 1366x768 --rate 75.03

and

xrandr --output DVI-I-1-1 --mode 1366x768 --rate 75.00

just gave all the same wonky effects.

The other resolutions did not show in the drop-down? I thought the would since they did show in the verbose output.

Given you have an 8th-gen Intel and many have found better performance with those using a newer kernel, perhaps the newer kernel might update the i915 driver and help this situation.

Open Update Manager. Select View > Linux Kernels and click Continue. Make sure 5.11 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear. Install the kernel and then reboot for it to become active.

[minty_tea]

Ok, so I updated the kernel from 5.4 to 5.11 and then it was no longer able to detect the screen, I guess because I installed the asus driver to the old kernel, and not the new kernel, so I tried to reinstall it again, but I am not able to on the 5.11 Kernel.

I ran the install script on, rebooted, and it didn't work. So I tried running the script with uninstall and the install and it gave an error. So I tried running it again with uninstall, rebooting and then with install and it is still giving an error.

When I run sudo ./displaylink-driver-5.3.1.34.run install

I see:

I just went back and checked the ASUS driver you installed and it indicates "Support Ubuntu 20.04, 19.04 and 18.04 & Linux Kernel version range is from 4.15 to 5.5." which is apparently why it didn't work on the 5.11 kernel. Sorry, I did not think of that before suggesting the newer kernel.

I went and checked the DisplayLink USB Graphics Software for Ubuntu and release 5.4 according its release notes "- Added support for kernel 5.11 and 5.12.".

However, as I indicated earlier in this thread (below), some people had to make adjustments to get the drivers from the DisplayLink website to work.

If not, here is DisplayLink information in a post from someone whose manufacturer did not have a driver for them to download so they used the publicly available DisplayLink driver with some patches.

That post links to some other posts and there was a little trial and error in several of those threads, so I am not able to give you specific instructions (although there is the possibility it will work right out of the box for you since you would be the first person I know to test it with the 5.11 kernel). I suggest taking a Timeshift snapshot before working with the newer driver and any patches. You would also want to remove the ASUS driver before installing the newer driver.

Or you can just switch back to the 5.4 kernel and use what you currently have installed. Let me know if you want to do that and need instructions to do so.

First before seeing this reply, I went back to my original kernel and reinstalled the driver there.

After seeing this reply, I went back to kernel 5.11, and installed the displaylink driver you pointed to in the link, and yeah, it works with the newer kernel, but I still have the same problem of only being able to use the screen at 1024x768 instead of 1366x768 which I have realized is quite sub optimal - as I can't even have 2 side by side pieces of code with 80 columns of text, on it at 1024 wide.

Maybe those links you pointed to will have info on how to tinker with it to get it to work at full resolution.

Maybe those links you pointed to will have info on how to tinker with it to get it to work at full resolution.

You can check those, but my understanding is they needed to make those changes to get a display on their external monitor. I do not recall any of them having issues with the resolution of what was displayed.

One of those links led to a post on the DisplayLink forum and that is where the patches was described. Here is the Threads in Forum : Linux and Open Source section. Maybe something there will be of help since you apparently do not need the patch to get a display (although maybe it might help the issue you are experiencing). I recommend using Timeshift snapshots when experimenting.

I found a solution that allows me to have near full resolution, at 1360x768 instead of 1366x768 and that seems to be good enough, it does allow for 2 vim windows with 80 columns side by side on the screen.

The solution was a script by Jei from this link, where having basically the same problem of a sckewed screen when using full resolution with display link driver: https://displaylink.org/forum/showthread.php?t=66356

I used that script and added it as a startup app, to automate it at the beginning.

After that, there was one little improvement I added, to better handle another program I was running, called Synergy by Symless

Synergy by Symless for sharing my mouse and keyboard with other computers; I discovered a problem where upon changing screen resolution with synergy going, there would be a weird problem where synergy wouldn't know that the total screen width for my computer had changed and would not let me access the far right of my laptop, but instead skip it to the next screen. I found someone else who had the same problem here:

https://forums.symless.com/topic/5431-s ... mand-line/

And I combined the first script with UniTrader's solution along with "-c configuration_file_path" as an option on synergys (synergys is for synergy server and synergyc is for synergy client - the computer that has had this second screen problem is running synergy as the server).

The combined script I created looked like this:

----------------------------------------------------------------

#!/bin/bash

killall synergys

# Adjust these parameters to your needs.
# These worked for me (AOC E1659Fwu)
OUTPUT="DVI-I-1-1"
HORIZONTAL_RES="1360"
VERTICAL_RES="768"

MODELINE="$(cvt ${HORIZONTAL_RES} ${VERTICAL_RES} | tail -n 1 | awk '{for (i=3; i<=NF; i++) print $i}')"
MODELINE_NAME=$(echo ${MODELINE} | awk '{print $1}' | sed -e 's/^"//' -e 's/"$//')

echo "Modeline:"
echo ${MODELINE_NAME} ${MODELINE}
echo

echo "[*] xrandr --newmode"
xrandr -d :0 --newmode ${MODELINE_NAME} ${MODELINE}

echo "[*] xrandr --addmode (${OUTPUT})"
xrandr -d :0 --addmode "${OUTPUT}" ${MODELINE_NAME}

echo "[*] Set new resolution"
xrandr -d :0 --output "${OUTPUT}" --mode ${MODELINE_NAME}

synergys -c ~/.local/share/Synergy/Synergy/LastConfig.cfg

---------------------------------------------------------------------------------------------------

I made a directory called Scripts under my home directory, and called this script fixscreen and made it executable.

I put this script in Linux's mint start up application, and tested with rebooting, and all seems to be working, pretty well.
