Nothing happens

[ricaard]

After defining bus and file in which edid is defined, nothing happens. Actually some window with blue triangle in it pops up and script reads graphics information with following output:
sudo ./write-edid.sh 5 edid.bin
GL_RENDERER = Mesa Intel(R) HD Graphics 5500 (BDW GT2)
GL_VERSION = 4.6 (Compatibility Profile) Mesa 20.0.5
GL_VENDOR = Intel

Please help
Thanks

It's because the script calls 'line', which apparently is from mesa-demos. You will need to edit the script to fix this:
