[opensuse-factory] no access to desktop unless i use icewm
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

Use XFCE instead. Perhaps your issue is this: https://doc.opensuse.org/release-notes/x86_64/openSUSE/Leap/42.2/ 1.5 Nouveau 3D/DRI Driver May Crash KDE Applications Report Bug # With openSUSE Leap 42.2, the Nouveau Mesa/DRI driver for 2D/3D rendering is considered experimental. The Nouveau kernel/KMS driver and the Nouveau X.org/DDX driver for 2D rendering are still considered stable. When the Nouveau Mesa/DRI driver is in use, some applications may crash, especially KDE and Qt applications. The driver is now in a separate package called Mesa-dri-nouveau, which can be removed in case of problems. Without this driver installed, there is no hardware 3D acceleration support on any Nvidia GPU and no 2D acceleration on newer Nvidia GPUs that use Glamor for fast 2D operations. Kernel Mode Setting and basic 2D are still available, as is 2D acceleration via EXA on GPUs from the Nvidia GPU generation code-named Kepler (introduced in 2012) and earlier. 3D operations are supported via software rendering.

I only had the icewm option on the tools menu at the time, i just wanted to see if any other sessions worked to see if nouveau was okay.

I spent all day yesterday trying all sorts of configs and i did disable that at one point. I took Fabian's suggestion of uninstalling nvidia completely and now it seems fine.

The nvidia driver does not only consist of a kernel module, it also replaces the system's libGL and various other libs. You need to uninstall nvidia completely and reboot to return to nouveau. The failsafe session does not work with the nvidia driver probably because it does not support the LIBGL_ALWAYS_SOFTWARE environment variable. Cheers, Fabian

Thanks for the solution.
