I decided to try an upgrade to kUbuntu 14.10 x64 to try out KDE Plasma 5. Since then, I just get a blank screens (x2) instead of the login screen. The following can be seen in the Xorg log:
To fix this, I have to SSH into my desktop and issue the following as root:
[b]service sddm stop
killall Xorg
service sddm start[/b]
I then have the login screen and all works. But if I reboot I have to repeat these steps, or I have to repeat these steps each time I turn my PC on. Damn its getting annoying. I tried rolling back to an earlier driver which did not have this problem and it is still doing the same thing. I can only assume that after doing a system update, some compatibility problem exists? 346.35 only started doing this after the update to the OS…
Still, its the nvidia driver having the Wobbly…
Nvidia driver 346.35
