Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.0 Update 1 and earlier, you may see these two error messages when you launch the Intel Quartus Prime GUI in Linux.
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
To work around this problem, set the following environment variables in a Linux terminal.
Bash:
export QMLSCENE_DEVICE=softwarecontext
export LIBGL_ALWAYS_INDIRECT=y
C Shell:
setenv QMLSCENE_DEVICE softwarecontext
setenv LIBGL_ALWAYS_INDIRECT y
This problem is fixed beginning with the Intel Quartus Prime Pro Edition software version 18.1
