libGL error: unable to load driver: swrast_dri.so

[jvandenbroek]

Tried this docker image on Xubuntu 17.10 amd64, but I get the following error when running scrcpy:

/ # scrcpy

Hey @jvandenbroek, could you try the nvidiaversion of the image?

[jvandenbroek]

Hi , I actually tried that version.. Not sure why it's not working?

[pierlon]

Try specifying a max size. Eg: scrcpy -m 1024

[jvandenbroek]

Tnx, but no change. I think it has to do with that I'm using the official Nvidia driver, not the open source one. Tried to figure out how to install this, but doesn't seem straightforward for Alpine. A well, may try it again later, probably need an image based on Debian or Ubuntu :)

for me specifying the max size works, I guess scrcpy doesn't like when the device is running a resolution higher than the one the X server is using.
I also get those errors like

libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi

But since it works are these just red herrings?
However if you are getting errors with swrast_dri.so that maybe means you are using software rendering and not actually nvidia drivers on the X server

same error.

I used command

% docker run --rm -i -t --privileged \                                             
    -v /dev/bus/usb:/dev/bus/usb \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e DISPLAY=$DISPLAY \
    pierlo1/scrcpy:nvidia

to run image

having the same error here libGL error: unable to load driver: swrast_dri.so

[waahhhh]

I'm using Ubuntu in VirtualBox. The host system has a nvidia GPU.
Got a similar error message:

Installing mesa-dri-swrast & mesa-dri-vmwgfx resolved it.

### runner (nvidia)
FROM runner AS nvidia

RUN apk add --no-cache mesa-dri-nouveau mesa-dri-swrast mesa-dri-vmwgfx

FWIW if anyone else hits this issue. I'm running on Alpine Linux v3.17 on latest WSl-2 and was missing

/usr/lib/xorg/modules/dri/swrast_dri.so

Doing

sudo apk add mesa-dri-gallium

fixed my issue prior to installing this I was getting:

glxinfo

Already fixed in a "newer" pull request. Still waiting for merge. See: #25
