Unable to interact if laptop lid is closed (TV works) #4296
Comments
I would like to note: for comparison, this edge case works on teamviewer. I don't know what they're doing to make it work, but it does. Switchable graphics are also quite common. There are many laptops with both an igpu + dgpu combination sold so this "edge case" actually appears frequently in the wild. |
I'm having this issue as well. Most modern laptops have switchable GPUs/dGPUs... saying it's a corner case is tone-deaf. It's not. Anydesk handles this just fine, so does Teamviewer. However, I just tested this on my Samsung Galaxy Book 3 360, which only has Iris XE graphics and it does the same thing. Lid closed -> no screen update and no interaction. Lid open -> works just fine. This doesn't appear to be isolated to dGPU/iGPU issues on laptop... this affects iGPUs as well. |
We do not have clue to solve this issue yet, help wanted. |
afaik it is done through the virtual monitor driver but I don't know more than that, something about a generic pnp monitor I've been using a HDMI dummy dongle for the time being |
How can I help? If there's something I can do from this end, I'll be happy to do it. |
Had the same issue with an iGPU. With the RD ending up somewhere between extremely unresponsive and downright stuck. So I thought that maybe it could be linked to Windows putting your Laptop into low-power mode if you close the lid. Throttling down the CPU and therefore also the GPU.
Maybe that can also fix your full screen freeze. |
same issue with an iGPU I recently tested it on a laptop with only an igpu and closed the lid, I did run into the same issue. I will correct my post |
Bug Description
on any laptop, if you close the laptop lid, you cannot control the remote desktop. This is true even if you have the virtual display installed from nightly.
old
On any laptop with switchable graphics (i.e. igpu + dgpu), if you close the laptop lid you cannot control the remote desktop.
This is true even if you have the virtual display installed from nightly. I tested this on 2 laptops.
My test setup is a T470p with an intel 630 igpu and a NVidia 940MX dgpu. I also briefly tested this on a P52 with an intel 630 igpu and P3200 dgpu. It does not work on both. As soon as you open the lid, you are able to resume controlling the desktop.
On a laptop with /only/ igpu, you can control the desktop if the lid is closed.
I tested this with hardware acceleration both turned on (default) and off. In both cases, the result was the same (could not interact with remote desktop).
Are there any (recommended) fixes for this, either through software, system settings (BIOS, LidAlwaysOpen, or otherwise) or hardware?
How to Reproduce
install rustdesk on any laptop
try to control it with the lid closed
Expected Behavior
should be able to control remote desktop.
Operating system(s) on local side and remote side
Windows 11 -> Windows 11
RustDesk Version(s) on local side and remote side
1.2.0 nightly -> 1.2.0 nightly (both Oct 20, 2022)
Screenshots
N/A, screen just stays stuck
