This is after every emerge world.

WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:

media-libs/mesa:0

                    ^^ 

dev-python/ipykernel:0

Any hints on how to correctly update these two would be gratefully received.

[SOLVED] Thanks to Hu and grknight for precisely the correct info. I followed the VirtualBox Wiki advice: set VIDEO_CARDS="" in make.conf, unmerge xf86-video-vmware (which is needed only if Gentoo is a VMware guest: not my situation), and re-emerge world. This fixed mesa. Evidently ipyparallel will eventually be updated and the conflict with ipykernel will disappear. I'll wait. [/SOLVED]

For mesa, the issue is that the newer mesa lacks USE=xa, but xf86-video-vmware requires it. Options: remove vmware; update vmware to a version without that requirement (if one exists).

For ipykernel, your installed ipyparallel is incompatible with ipykernel 7 and above. Options: remove ipyparallel; update ipyparallel to a version with a looser constraint (if such an ipyparallel exists). As of my last sync, I do not see a newer ipyparallel.

See this topic as to why x86-video-vmware is dead. Mesa dropped its required integration.

The latter is currently not solvable if dev-python/ipyparallel is installed as it would seem to require a certain version and will likely be updated at some point.

This VBox Wiki suggests VIDEO_CARDS="" in make.conf and re-emerging world. Currently

Code: Select all

# grep VIDEO_CARDS make.conf
VIDEO_CARDS="nvidia nv vesa fbdev vga"

as I am usng nvidia-drivers and I have VBox Win11 and Ubuntu guests.

Is it "safe" to follow the VIDEO_CARDS advice?

xf86-video-vmware is only for guests and not the host. How did it get installed? I would suggest removal of that package if you do not have a Gentoo guest on VMWare.

Edit: also the related wiki page mentioned is only for guests
