As said here [Cannot start GenICamBrowser - libpng missing](https://forum.commonvisionblox.com/t/cannot-start-genicambrowser-libpng-missing/523/17?u=ss_silkke), I needed to add a few env vars to the .xsessionrc file :

```auto
CVB=/opt/cvb
GENICAM_GENTL64_PATH=/opt/cvb/drivers/genicam
CVGENICAM_REGISTRY=/var/opt/cvb/Registry
GENICAM_CACHE_V3_0=/var/opt/cvb/genicam
CVBDATA=/var/opt/cvb
CVBCONFIG=/etc/opt/cvb

```
