So with this Kubuntu had not tried. But Netrunner 17 based on Kubuntu, I think that the problem would be the same.
Still … even if I do not update the kernel, the Mesa drivers do not update and leave everything as you have it in your OS, I still have these problems! whether with new Mesa and kernel or without new Mesa or kernel. The problems Netrunner 7 remain the same, this sddm 0.13 makes problems!
And the question is, what do I do? The seems to me that Netrunner 7 my graphics card does not recognize correctly, configured, and then lead to this fatal error. I wrote, I have these problems even if I use your kernel and Mesa. So the old versions.
Just a thought, have you given the proprietary catalyst drivers a try yet?
I have one system that is a bit older (nvidia nforce 430 / AMD 64) and I have to use the legacy NVIDIA proprietary drivers on it, otherwise I get the same garbled screen and system freeze after a few minutes of the system running using the nouveau drivers. The only other way around the issue was to add option “ShadowFB” “on” to my xorg.conf file for the nouveau drivers to not crash my system, still the proprietary drivers work better as there is no screen tearing, but that’s another story.
I run the rolling edition so I usually encounter, or at least here of these kinds of issues before the Ubuntu version does, still I haven’t heard of this one up until now.
Ah, if after trying the catalyst drivers your issues began then we have a place to start.
Are you sure that the catalyst drivers are completely removed, and that the radeon drivers are no longer black listed and installed properly?
Nevertheless, we can not get around it that sddm caused big problems with me. And coming when Netrunner pulls the updates when it is first installed. Without these updates, I do not have these problems.
The only question is, what can I do. Again reinstall? That would be the fourth time.
We’ve been using sddm 0.13.0 under arch now since 2015-12-07 and haven’t had any issues with it. All the issues we did have with it were due to the Intel + mesa drivers. We have however had issues reported about kernels 4.4.5 and 4.5-rcX and their radeon drivers causing the xorg server error: unable to connect to server.
No, nothing else has been updated. Only KDE, then the program, a new kernel and sddm. And if I use your kernel and the update put the Netrunner offers me, then the problems begin. Only colored bars on my screen. And before the updates, everything works fine. Only then the problems begin, when you start shaking your Netrunner Logo and then nothing works.
Since the rolling edition already has the 4.4 kernel, sddm 0.13.0 xorg 1.17.4 and xf86-video-ati 7.6.1 could you download the 2016.01 ISO and see if it boots up in live mode, then ctrl+backspace to see if the sddm login screen appears.
