Greetings I had some issues with my system and although I didn't need to, in retrospect, re-install - - - well I did. Running as previously, on Debian testing (10 or buster) with a pile of ram and and (lots of resources), with what may be more unusual is 2 graphics cards and 4 monitors set up as 2 x-screens. (Would love to condense that into 1 screen if someone has the know how and can describe it but 2 works well enough even if 1 would be quite slick (and very 'interesting').) So on this new install I have been working to install the interesting (?) programs that I have had previously. In reading emails I noticed that I was unable to copy and paste using ctrl-c and ctrl-v. Have been looking at key bindings and the clipboard. Have reinstall x11-apps and lxsession as both are linked to clipboard use. Have also reinstall all the xkb resources (that I can find). Still no joy though! Any ideas or suggestions as to the culprit (or the recalcitrant directories/files whatever) would be gratefully accepted. Regards Dee
