I did not expect this to happen soon, so I suggest that this bug report just remains open for now. If I have time I will try to find out what is the difference in /var/lib/plasmalogin between the working and non-working version. Maybe that can give some clue.(In reply to Aros from comment #3) > (In reply to bxschmidt from comment #2) > > (In reply to Aros from comment #1) > > > (In reply to bxschmidt from comment #0) > > > > Created attachment 194905 [details] > > > > Screenshot of distorted login screen > > > > > > > > DESCRIPTION > > > > I get a distorted and flickering login screen on my primary monitor > > > > when I > > > > connect my Philips TV (See attachment).

I did not expect this to be fixed soon anyway, so I suggest we leave this bug report open for now. If I have time I will try to find out what is the difference in /var/lib/plasmalogin between the working and non-working version if this is possible. Maybe that will give a clue what is going on. -- You are receiving this mail because: You are watching all bug changes.
