MX-17 Beta 1 Feedback Thread

[BitJam]

The problem is that optirun is looking for a command, not an environment variable. Quotes won't help but this might work:

Code: Select all

vblank_mode=0 optirun  glxgears

I have installed MX-16.1 (September) and runs pretty well. Indeed, it is a very good distro. Two days ago I tried live MX-17 B1 (and before a4 and a5) and noticed that ram consumption is much higher than MX-16.1 live. Why is that? It can be explained? Thanks.

Me too experienced my system is slow after installing mx-17 beta on my pc and reverted back to MX- 16.1 may be due to alpha version i think so or may be my hardware species are becoming old but in mx-16.1 i din't found any lagging

Try:

Code: Select all

optirun vblank_mode=0 glxgears

Must be an error in the code

Code: Select all

[ 1939.715915] [ERROR]Error running "vblank_mode=0": No such file or directory

The vblank_mode=0 thing works for me without the optirun part (don't have a Nvidia GPU), maybe try putting some quotes around it:

Code: Select all

 optirun 'vblank_mode=0 glxgears'

Does not work with optirun but does alone.

Did you try BitJam's way ?

That command to disable the refresh sync only works on xorg drivers like Intel and maybe the xorg AMD drivers. The correct syntax for the Nvidia nonfree driver is

Code: Select all

__GL_SYNC_TO_VBLANK=1 optirun glxgears

But glxgears is not a good benchmark, and will show a lower rate for the Nvidia card for reasons that seem related to Bumblebee overhead. The Unigine benchmarks show better frame rates for my Nvidia GPU.

One benchmark that works a lot better is to install virtualgl and use glxspheres on 32-bit and glxspheres64 on 64, but I still have to build it for MX 17...the way I quick-check if Bumblebee is working is

Code: Select all

inxi -G

vs

Code: Select all

optirun inxi -G

Code: Select all

optirun inxi -G
Graphics:  Card-1: Intel 3rd Gen Core processor Graphics Controller
           Card-2: NVIDIA GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M]
           Display Server: x11 (X.Org 1.19.2 ) drivers: modesetting (unloaded: fbdev,vesa)
           Resolution: 1366x768@59.99hz
           OpenGL: renderer: GeForce GT 720M/PCIe/SSE2 version: 4.5.0 NVIDIA 375.82

That is what I would expect to see for the OpenGL renderer. So it looks like everything is as expected.
I did not see Bitjam's solution until now. That did indeed work. And the result is an order of magnitude increase in frame rate, from about 60 fps to 1000 fps

[Stevo]

But isn't that 1000 fps a lot slower than the integrated GPU? My Intel GPU shows a 10X better framerate!

Here is the latest virtualgl: https://drive.google.com/open?id=1GEVdo ... mBjoYDMKec

You only need to install the virtualgl deb for your release and architecture, then you get the glxspheres benchmark on 32 and glxspheres64 on 64-bit. They show the Nvidia GPU as faster without that VBLANK setting...

[richb]

No it is 60 for the integrated intel.

Thanks. I am not on the laptop right now. But will get it when I am. By the way I remembered glxspheres is a better comparison. It will be interesting to see how that fares.

Similar numbers with glxspheres64

Is there an hdmi sound card or device showing?

Sometimes those need to be turned off or de-selected.

No hdmi sound card. I found something strange: Some program (for ex. Telegram) ran but I couldn't change it's output device to USB earphones but some could (for ex. Clementine).
