I got bitten by #856351 after upgrading to Debian 9 yesterday. I want to be able to boot up, log in without any fancy login manager (not to mention Desktop Environments), and then run 'startx' and go X11. I need to do this repeatedly, on different virtual consoles -- so I can have simultaneous graphical logins. Or rather, so I can have a login and my Mom can have another one.
Anyway, what worked for me was to add needs_root_rights=yes to /etc/X11/Xwrapper.config, as described in the corresponding man page. I haven't checked why this is needed, with my particular hardware. (And I haven't verified that it fits my two-user scenario above; it would be sad and a serious regression if it didn't.) /J�rgen -- // J�rgen Grahn | mot du jour: Terylen \X/ <[email protected]> |
