Issue with MESA-LOADER #80

eleonoravercesi commented 3 years ago

Hi all, I am not able to run VirtScreen, even if I follow the instructions properly. The error message is:

libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)

Thank you!

I am having the same issue, I can't make it work.

i was able to get passed this using python install.

pip install virtscreen

however then i have the issue with no Virtual1 showing up, after adding config to /usr/share/X11/xorg.conf.d/20-intel.conf main screen loads glitchy with tears and distorted. Still haven't been able to get this working on Ubuntu 20.04. This method breaks main screen usability.

I tried to proceed by add modes to DP-1 and can get app to open up but then proceed with this error if trying to use DP-1 instead of Virtual1.

['xrandr', '--output', 'DP-1', '--mode', '2736x2048_virt'] xrandr: Configure crtc 1 failed

@420coupe the old intel drivers for 20-intel.conf will no longer work for this. Intel Iris I believe it uses a new drivers, I have a hard time finding what the new driver is. I tried changing it to iris since that is what the error says:

libGL error: failed to load driver: iris This is my current xorg file, but it doesn't work.

Section "Device"
  Identifier "intelgpu0"
  Driver "iris"
  Option "VirtualHeads" "1"
EndSection

those failures have nothing to do with the conf file, program installed incorrectly. Try installing using python as posted above.
