qdbus org.kde.KWin /Compositor suspend - Has Bad Results?

[JeZ-l-Lee]

Hi,

I found these commands on the web to disable and re-enable desktop compositor:

qdbus org.kde.KWin /Compositor suspend
qdbus org.kde.KWin /Compositor resume

When I "suspend" the desktop compositor bad things happen:
- Workspace changing does not work?
- Also I am unable to see apps open on different workspaces
(only shown apps from current workspace when the "suspend" occurred?)

I am doing the above in an effort to get Linux Steam game client working properly.
When surfing Linux Steam after some time the desktop goes completely black.
(only option is to pull up a Konsole and reboot)

Let me know, thanks!

alt-shift-f12 performs the command as well
The steam client does not use compositing, as far as I can recall, except maybe if it is run in Big Picture mode (full screen, sofa-friendly interface), if that helps any.
Individual games can request to stop compositing to help increase performance, you can disable this in System Settings' compositor section. You might try different opengl settings there as well, say using 2.0 vs 3.1 (this only is for the desktop, it does not affect games)

I am not seeing the same thing you are, as I ma using Intel graphics on my laptop, perhaps on Nvidia it is happening there? I will check that later when I can get to my home PC.

I spy some people having crashes, but nothing recent and fixes are not common. Some do specifically seem to involve the gtx 970, though...
Sorry I haven't been of much help here

Hi,

Did not know about [Alt]+[Shift]+[F12], I will use that instead.
My Kubuntu compositor defaulted to OpenGL 2.0 so I will try 3.1.
Thanks!

Hi,

I researched the current nVidia Linux driver and they said the black screen issue is fixed in the newer driver.
I updated from here: https://launchpad.net/~graphics-driv...ive/ubuntu/ppa
Thanks!

Cool, I have that driver (396 beta) Rise of the Tomb Raider needs it. It works perfectly fine for me, but so did 390, and I do not usually suggest beta drivers off the bat. I don't think I have played metro 2033 on 396 yet. I was gonna, but got a fever strong enough to keep me mostly afk over the weekend.

Hi,

If you bought original "Metro 2033" on Valve's Steam, you can get the new "Metro Redux" collection at a discount.
Original "Metro 2033" had some issue and the new "Redux" versions fix them as well as introduce beautiful new visuals.
I haven't tested Linux Steam with new nVidia drivers yet - probably tomorrow.
Feel better, thanks!

Thanks, I am quite a bit better today.

I bought the redux pack a few months back Never played the originals. There is a new Metro game coming this year-ish, hopefully they can get it on Linux fairly quickly.
The last game I played on Windows was probably Grim Fandango
I have never played any Half Life game in Windows, either. it is fairly interesting to play some of the HL2 games at 4k resolution on a 43 inch TV
