Hi Fell foul of the unable to build nvidia against new 4.9 kernels - something about missing files or sources compiled against wrong versions. So i thought, simple, go back to nouveau, just a matter of removing a blacklist line in a file. Unfortunately not, I get the login (kdm) list, enter my password for the user i selected and then get this message "Plasma is unable to start as it could not correctly use OpenGL 2" - i'm sure my config was set to use opengl 3.x when using nvidia driver. I have to ctrl backspace backspace to return to login list after clearing the popup error message. i've searched the web for this message and did not find any suitable ways of correcting the problem . Any ideas? I've tried to log in using the plasma failsafe session (?) but that results in getting the same message. I can log in using icewm but thats no good to me and nothing i need runs properly. regards Ian Up to date tumbleweed/kde/plasma etc I'm using a web interface on a win10 to send this email hence no definitive version numbers. Just downloaded latest tumbleweed iso in case i have to reinstall -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
