[SOLVED] Salvaging SDDM and Plasma (different video card)

Hi,

My Nvidia card is no longer working, I had to revert to the onboard Intel graphics. First, it was autologin into Plasma; it did not start, reporting OpenGL errors, which was understandable, under the circumstances. Much worse, I got smartly trapped inside dysfunctional DE: no logging out, and no virtual console (Ctrl+Alt+F.. not working, too). Nothing short of the hard reset helped.

I tried to reconfigure SDDM; it is now back to the default configuration according to Archwiki, and shows nothing except for a black screen and a mouse cursor. So I stopped the SDDM daemon and configured Fluxbox as the only desktop environment. I can live on, and the standby desktop is good.

What steps can I take to set SDDM and Plasma back to rights?

xorg-server 1.20 reportedly has problems with sddm (or rather, sddm has problems with it) so reverting to 1.19 might help - although personally I had completely different symptoms.

Wait, so you set up fluxbox just because you couldn't start kde with sddm?

You can start kde from xinitrc.

Not exactly. Fluxbox always existed as an emergency resort . I just moved it from SDDM to .xinitrc.

You can start kde from xinitrc.

It is not that easy. KDE autostarted as always, then failed very uncomfortably: no desktop, no control center to turn off effects, no logout and no virtual console (Ctrl+Alt+F..). Just a windowed message about an OpenGL error. I've been wondering how to go about salvaging KDE ever since. Turning off bells and whistles would probably do the trick (?).

Yes, I've got an impression that in my case SDDM has nothing to do with the problem. It's my clumsy attempt at disabling the autostart. Now I've got the SDDM and the Plasma to salvage .

No, SDDM hasn't any problems with xorg-server 1.20. NVidia has. See: https://bugs.archlinux.org/task/58660, https://bbs.archlinux.org/viewtopic.php?id=237045, https://forum.archlinux.org.pl/viewtopic.php?pid=4237 (in Polish, but it's very simple to translate) and https://devtalk.nvidia.com/default/topi … st/5260453

Thanks, all!

All one has to do going from Nvidia to Intel is

$ sudo pacman -R nvidia-340xx-utils

or whatever Nvidia utils are there.
