Maybe even the kde ones? The make.profile choice switches on/off certain USE flags and specifies a set of system packages for the particular profile. These will in turn drag in other packages as dependencies when you update your system. Therefore, unless you go for a minimalist make.profile you should not need to be emerging packages one at a time to get a functional desktop, although you will need to emerge individual applications of choice if these are not already included in the DE default set of packages. More details: https://wiki.gentoo.org/wiki/Profile_(Portage) KDE applications are mostly grouped in meta packages. These are meant to be installed selectively. For example I install 'kde-apps/kdepim-meta' because I use Kmail, but will not install 'kde-apps/kdegames-meta' because I don't run any games applications. > (Having re-read the KDE page, it's suddenly making a lot more sense, but > that's with hindsight. But am I right that the profile modifies the > system set of packages?) Yes, as I mention above, it modifies USE flags and specifies a set of system packages too. You could have started with a stripped down profile, like 'default/linux/ amd64/17.1/systemd (stable)' and then spend a lot of time tweaking USE flags and installing various packages and meta packages to get to the same end result. Thanks to Gentoo devs, all this work is no longer necessary since there are more make.profile options to choose from. :-) signature.asc Description: This is a digitally signed message part.

Yes, you can't expect a DE to work if major packages are missing. ;-) This is where it would be nice to have something like the handbook, or a chapter in the handbook, on bringing up a working graphical environment. It is not in the Handbook, which has the purpose of installing the Gentoo OS itself, but it is in the Gentoo Documentation - look at the dropdown menu 'Documentation' of the Handbook web pages: https://wiki.gentoo.org/wiki/Category:Desktop In your case, as I posted previously, you need: https://wiki.gentoo.org/wiki/KDE I'm currently emerging kde-apps-meta, because I discovered that plasma (once I'd got it working) was missing all sorts of things - like konsole! But that kde page you pointed me at only mentions it in passing! It's the classic problem that man pages are very good as reference, but if you don't know what they're talking about they are very bad at enlightening you. A "dummies guide to plasma" would have been very useful telling me the packages I needed to emerge and why would have been very useful. Now I'm getting my head round it it's all falling into place, but I've been unable to see the trees for the forest :-) But, from the errors you've been getting with startx it seems you haven't read relevant Xorg documentation either. Now to get something like sddm working :-) For SDDM you better read this first: https://wiki.gentoo.org/wiki/SDDM And I'll probably be tearing my hair out screaming because I'm straying into unknown territory again :-) I doubt many people run multi-seat, so that'll be fun ... (and I gather some of these greeters don't support it, either :-( (Plus updating my SUSE version to 15.3, re-organising my hardware, blah blah blah :-) Cheers, Wol Glad you got your desktop going! :-) Thanks. At least I'm back on familiar territory there. Here's hoping for a lot more foresight :-) Cheers, Wol
