Try to login as a new user (or move your home directory out of the way). If it works start selectively deleting dot files/directories from your home directory. Start with .cache, .kde4 and everything that starts with a k in .config and .local and go from there. I had the exact same problem when I upgraded one of my laptops and that's how I fixed it. Also delete anything in /var/cache and any files belonging to your uses in /tmp and /run. You can also try switching to a VT and kill plasmashell and if it doesn't restart automatically start it with the DISPLAY environment variable properly set. Also look at the system logs, .xsession-errors, xorg logs, etc for clues. You can also run kdebugdialog5 from another DE to enable a lot of kde debug output to the system logs. > > > Thanks > > Robin > > -- > > ---------------------------------------------------------------------- > > Robin Atwood. > > > > "Ship me somewheres east of Suez, where the best is like the > worst, > > Where there ain't no Ten Commandments an' a man can raise a > thirst" > > from "Mandalay" by Rudyard Kipling > > ---------------------------------------------------------------------- > > > > > > > > > > > > > > > > > > > > > > -- This message has been scanned for viruses and dangerous content > by *MailScanner* <http://www.mailscanner.info/>, and is believed to > be clean. -- Fernando Rodriguez
