still not working

[rustdesk]

How about this one https://github.com/rustdesk/rustdesk/releases/download/1.1.8/rustdesk-1.1.8-skia.zip?

[Ray8716397]

tried it before

[rustdesk]

It is an old issue, but sadly, I can not reproduce on my PCs and virtual machines.

[Ray8716397]

seems like no error log at all.

Embarassing.

[rustdesk]

Can you build and run from source code?

[Ray8716397]

i‘ll try,no rust exprience though.

Thanks, if any question please ask.

[rustdesk]

@Ray8716397 can you build and run this one, https://gitlab.com/rustdesk-official/rustdesk-debug.git? It only depends on rust-sciter. Please install rust first https://rustup.rs/. Then run it in git bash, cargo run.

Thank you so much, can you replace src/index.html with a very simple one, and run again? like this
xxx

[Ray8716397]

？how ，sorry i dont undersand

Change the content of https://gitlab.com/rustdesk-official/rustdesk-debug/-/blob/main/src/index.html to xxx

[Ray8716397]

[rustdesk]

Could you please git pull? you will see a new directory test. There is an executable scapp.exe. Can you run it and test index.html and xxx.html under the same directory?

[Ray8716397]

[rustdesk]

@c-smile any input? https://gitlab.com/rustdesk-official/rustdesk-debug/-/tree/main/test

[rustdesk]

Could you tell us the system info of your Windows? Hope @c-smile the author of Sciter can give some advice.

is there a command line version i can run on windows linux sub system?

[rustdesk]

is there a command line version i can run on windows linux sub system?

Yes,

rustdesk/src/main.rs

Line 110 in 5af1258

fn main() {

But I have not maintained it any more.

[c-smile]

Please try the same but from folder/path that contains only ASCII symbols. What you will get?
I suspect problem is in incorrect file:// url encoding so asking.

[rustdesk]

ASCII

Scapp works fine with non-ASCII path on my Windows, but not sure about @Ray8716397

[c-smile]

May I get exact path where scapp fails (to test it here) ?

[rustdesk]

test it here

I can not reproduce this issue on my Windows. Only @Ray8716397 can

[dinojs]

Facing the same issue on Windows 11.

Could you run from source and get some clue?

This may help,

I get this issue. But also with teamviewer and edge on the same machine. When moving the window edge briefly shows it content then disappears. I am looking to replace teamviewer with rust desk. I'm going to guess its some kind of hardware acceleration issue.

Confirmed. (with edge at least) disabling hardware acceleration for edge restored normal behaviour. So I assume a "disable hardware acceleration" option would resolve this as its not the software itself with the problem its the host machine.

[cmucgit]

Any news on this? I'm having this exact same issue in 2 of my machines

[rustdesk]

Rewriting with Flutter desktop.

[cmucgit]

Ok, thanks. Just a quick note for others, I saw the solution somewhere else, downloading and installing this driver fixed the issue for now:
https://www.amyuni.com/downloads/usbmmidd_v2.zip

https://www.amyuni.com/forum/viewtopic.php?t=3030

[rustdesk]

https://www.amyuni.com/downloads/usbmmidd_v2.zip

Interesting, why is it related to a driver?

[cmucgit]

In my case, I'm trying to run RustDesk on virtual machines and all-in-one compact PCs that I use kind of as a remote console or KVM of some sort to access my servers. These machines have no monitors plugged in, and I get the blank white screen in RustDesk. But when I install the above monitor driver, it works.

[c-smile]

By default Sciter works in H/W accelerated mode - that requires video drivers to be present.
It also can operate without video drivers - by using software rasterization.
But that's need to be set on application side.

[rustdesk]

software rasterization

We have set this per you suggestion #132 (comment).

rustdesk/src/ui.rs

Line 82 in 92f1f17

sciter::GFX_LAYER::WARP

[wneiner]

This issue happened for me during testing to see if this was good to replace teamviewer. I couldn't get it to show anything in the window. In troubleshooting I found that it was Chrome Remote Desktop session that wasn't allowing it to be visible. I closed that and went in through an RDP session and the window was still sitting there but this time it is showing the information, no need to relaunch. Only difference of chrome remote and rdp.

Now it just needs UAC support, and this will be golden.

Thank you,

[grummbeer]

@Ray8716397 @dinojs have you tried the nightly version? https://github.com/rustdesk/rustdesk/releases/tag/nightly

Do you still have the white screen?

probably same as #80

A by far better solution for modern Windows versions is the installation of a Indirect Display Driver (IDD). You can find a working sample here (only sharing the link, not my software). https://github.com/ge9/IddSampleDriver.

If you are running a headless Windows system on kvm just install the QXL virtual GFX card & you should be fine.

[rustdesk]

a Indirect Display Driver (IDD)

We have done it, but we do not have EV certificate to run it.

[SystemFuchs]

The guy behind the above link has deployed the driver with the windows package manager Scoop

scoop bucket add extras
scoop bucket add nonportable
scoop install iddsampledriver-ge9-np -g

I've tested this & when you install it this way the driver seems to be signed (maybe self signed). But it does work,
here is also the thread in the original repo where the cert deployment is discussed:

roshkins/IddSampleDriver#26

[rustdesk]

But we need more control, e.g. change resolution, disable/enable it when monitor remove/add etc. So we modified it.

@fufesou check this, may be we do not have to use EV to sign our ldd driver. I do not think a sample driver has EV signed.

[SystemFuchs]

If you compile the drive with VS it has a options txt. In this file all resolutions are defined & can be changed through the windows system tool.

[rustdesk]

@SystemFuchs Thanks

[fufesou]

@SystemFuchs Thanks. I've tried install the driver manually. But I find the released package may be already signed.
I'm not familiar with signing. But we may need more steps to make our driver signed.

And I've asked the author what to do next to sign the driver. roshkins/IddSampleDriver#33

roshkins/IddSampleDriver#26

https://github.com/fufesou/RustDeskIddDriver/releases

[fufesou]

I've found the way to create test cert file. I'll test later.
https://learn.microsoft.com/en-us/windows-hardware/drivers/install/creating-test-certificates

[fufesou]

@rustdesk I can sign our driver with a test cert. But I'm not sure if it meets our current needs.
Maybe we can provide a prompt window for user to trust and install the cert?

[rustdesk]

go ahead with test cert first

I also encountered this today when I upgraded from Win8.1 Embedded Industry to Win10 LTSC 2019 on an old laptop.

The problem was in the latest version of the driver for the GPU Nvidia GeForce 710M
(it is possible that this can also be manifested on other GPU models built on the same Fermi 2.0 architecture).
The latest available driver version for this GPU "391.35" causes this problem.

The solution to this problem was to install the previous version of the driver "391.24".
But I think I have found the root cause of this problem. At least on the previous version of the driver, it causes this problem again under the following circumstances⤵️

Go to the "Nvidia Control Panel" in the options called "Manage 3D Settings", and switch the "Preferred graphics processor:" option from "Auto-select" to "Nvidia performance..." (this is a rough name for this the option, because I don't remember exactly. I took the screenshot below a couple of hours before writing this comment)⤵️

After applying these settings, the problem appears.

Currently, I have installed an even older version of the GPU driver "390.65", because the video game "Roblox" (which my nephew regularly plays on this laptop), like RustDesk, refuses to work, showing a solid white window even on the driver version "391.24" on which RustDesk works flawlessly.
