Hi !

SpaceDesk has been working great for me for quite some years. But since I yesterday had to upgrade the free version, all is misery. What happens is hard to describe, but it looks like interfering at hardware level (the video card), and from there (?) disturbing all on Windows. Restarting applications, completely freezing browsers, continuously resetting my windows monitors, make them black for several minutes … what not.
N.b.: The tablets I use SpaceDesk for show their contents as should.

I think it goes wrong at the moment which always has been a bit prone to error : when the external Android tablets are observed for disconnecting at a time-out I forgot by now, but say 3 minutes.
N.b.: The connection Loss Delay is (and was) set at 45, and the Connection Close delay is (and was) set at 0 – so all should stay connected. And, they *do* stay connected, but it is the Windows (10) host machine which goes bananas.
I tested with the the tablets kept on for 10-15 minutes, and then no issue. But at switching them off (to sleep), the misery starts – when the mentioned time-out elapses.

This is so intrusive that it needs minutes to recover, which recovering only can be done by setting the Driver Console to OFF.

I would be helped by using the old version again (I did not try to reinstall that), even if it would operate in black and white. That is, for during the time that you solve this for me severe issue (I got completely depended on this beautiful product !).

May it help your research, the happenings on the normally connected Windows monitors exhibit the same as switching their inputs. One thing about that which you may or may not recognize, is that a multimonitor RDC session shrinks to one monitor. This would happen too when the second monitor this RDC session is spread to, would be switched to another input (Windows now needs to show the content on the one monitor left).
Another possibly recognizable exhibit would be that no mouse-hovering is captured any more anywhere. This makes me think that the Windows Message Queueing is disturbed or shut off. For example, no desktop icon would highlight at hovering. Restarting Explorer.exe (the main one controlling the desktop) recovers from this.

I tried to install the latest Viewer version on the (3) tablets, but I think that 2.1.15 is the latest version and it was already installed on two of them. The third contained 2.2 and that downgraded to 2.1.15 after installing the latest version from Google Play. All were installed in May and June 2024 (as the SpaceDesk About shows it)

I changed nothing on any of the settings. Not after the upgrade to 2.1.31 and not after seeing the issues.

If I need to send diagnostic data, please say so and let me know how to get that to you.
I hope you can help !

A couple of things to add :

1.
I am pretty sure that the install of this latest version imposed a conflict with my nVidia drivers (GT730). This conflict exhibited throughout, thus also when SpaceDesk was not running (or after a reboot). Reinstall of the nVidia drivers did not help. Upgrading those to a newer version, *did* help. But it only helped the being inordinately intrusive (e.g. how to implement a new driver when all is continuously flashing).

2.
I am also pretty sure that this version now uses hardware acceleration. This is great of course, but where is the switch to set that Off ? (if I am correct at all about this).

3.
I am 100% sure that the disconnect time (the field filled with 0 or whatever other number) is not working any more. THIS now is what’s left for impossible usage. Thus, when my tablets are switched off, after 9 minutes (I measured it now), all what’s imposed on the tablets, fall back to my primary monitor and I can’t work any more (the windows/forms falling back to that monitor are all part of an application I continuously need/use, so I can’t minimize them). Also, this falling back is for Windows itself a permanent “thing”. Hence, I always lose my configuration (takes 20-30 minutes to re-setup *if* I can find all my forms again (all overlaying each other).

I noticed that when the tablets time out after being off (the 9 minutes), a brief notification on my main monitor is accompanied with that, saying something like “Android viewer: Spacedesk is free for non-commercial use only”. I don’t recall this notification, other than from the tablets themselves. Probably this is normal when the tablets have been removed from the “system” which normally never happened. Btw, I see this notification repeating after 15 minutes, one notification per tablet.

I forgot the procedure, but what determines that I am a “commercial user” ? Nothing changed on my side, and I am just sitting at home doing my things as always. One thing strange I could add : at the attempt to upgrade the tablets, I ran into a (Google Play) form asking me to pay. I don’t know why that happened, and since several apps for Spacedesk pop up in there, I possibly used a wrong one ?

After another 16-17 minutes I could capture the notification.

Hi @peterst2,

1. Please always update to the latest nVidia drivers to avoid such issues.
2. Hardware acceleration is not available in the latest spacedesk driver v2.1.31.
3. Configure ‘Connection Close Delay’ in spacedesk Driver Console to prevent unplugging of spacedesk virtual displays upon viewer disconnect.

As for the licensing notification, this appears every time the Android viewer reconnects.
For the Licensing Terms, please refer to this page: https://www.spacedesk.net/licensing/

What do you mean by this?

Well, this is what I did this morning (the 86400), and I take it that you recognize that 0 (zero) was infinite, previously ? Because … that seems to help. Please notice though, that it also seems that each tablet must first run into this, before the issues are beh9ind me. I mean, one tablet was off all the time, and since I switched that on and off again, all seems fine ?

Waited one hour before posting this, switched all on and off again a a couple of times and … flawlessly.
I can only conclude that the 86400 instead of 0 did the job (together with the latest nVidia driver).

Hi @peterst2,

the value ‘-1’ is infinite not ‘0’.

We are glad that spacedesk worked again on your side.

#6 · 07/01/2025, 10:31

Ahaaaa 🙂

FYI and FWIW : The 86400 did not work out, because long before that all turned into a mess again. And this remains so until … not sure … restarting of the Spacedesk control panel. And or … activating the tablets and let them reset / recapture the timeout again ? … all just guessing. But this morning I did something along those lines because else it kept on going wrong. In an attempt to summarize this :

If the tablets remain off (they sleep) for a longer time, things go wrong and this can be reset by waking the tablets. Then let them sleep again and all is fine for x (?) time, less than the set number of seconds (86400 in my case).
Yesterday I experienced similar and tried to report that (but it is all vague and difficult to repeat).

I will now set the value to -1 and will let know later whether that helped.

Thank you very much for bringing the -1 to my attention. I see from older screenshots that I indeed had -1 in there. Then FYI : this means that the install of the latest version changed that to 0, while other settings sustained from the previous version. Maybe you guys can adjust that for a next person running into this.

Thanks !

Unfortunately the mess is regularly still there. I can’t tell when it happens. It just does at random moments.

To picture this and hopefully see the severity :
– My tablets sleep;
– That “reset” occurs;
– All say 25 forms move from my tablets to my other monitors (usually my main monitor), overlaying everything;
– Waking up the tablets shows that all are still bound to their virtual monitors but now empty (see previous point).

Earlier today I discovered a situation that one tablet still had its contents after waking it up. So it looks like a “per tablet” situation; they one by one incur for the situation, unless I am there myself and somehow interrupt it (possibly by bringing up the Driver Console ? … I don’t know).

Please hand me suggestions on what I can try. And the actual guide is also something I could use; you may have a link to a page somewhere.

Thanks !

Hi @peterst2,

you might also need to set Connection loss delay to value ‘-1’.

#9 · 08/01/2025, 17:36

I have done that right after you told so, but an hour ago all went blank while I did nothing, and again the mess is there.

Hand you hand me a decent workflow to apply these changes ? (what to stop and what to start and in what sequence etc.). Please don’t say “all” to make it the easiest solution, because – for example – each time I restart the Spacedesk driver, I already incur for the mess.

Hi @peterst2,

Could you please describe your setup?

how many viewers are connected?
are you using wireless connection on all connected viewers?
are the displays in extended mode?
is it only the tablets that go to sleep or the Windows machine as well?

Please also try the following steps:

set -1 to both Connection loss delay and Connection close delay
turn spacedesk Driver OFF then ON
reconnect the viewers
