Can't Connect to X Server (Solved)

Gabachin · 2024-01-01 14:21:28

After a recent Arch update, I found I could not log into my system. I did remove several orphaned packages but aside from that, there were no issues with the update as far as I could tell. But on reboot, the sddm display manager showed a blank screen. I tried with lightdm, with the same result. Then I disabled the display manager altogether and tried to connect with startx. I got a connection refused by the server error. Here is the log:

Using the intel ddx on a Kaby Lake iGPU is a terrible idea.

Gabachin · 2024-01-01 15:15:58

I unistalled the xf86-video-intel drivers and installed the mesa-amber video package, enabled sddm and now it is working. Still have the question though, as to why all of a sudden it broke, since I have been using the system for a year now (vanilla Arch + i3) with no problems.

Scimmia · 2024-01-01 15:20:45

you either uninstall the intel ddx OR install mesa-amber, not both. For Kaby lake, you don't want to be anywhere near mesa-amber.

Your setup has been broken since the start and it's falling back to software rendering. New mesa has a bug in swrast, but you should have never been hitting that anyway.

It's not, you're using the legacy driver. You do NOT want mesa-amber.

Gabachin · 2024-01-01 20:37:02

OK, so what do I do? Unistall mesa-amber? And install which driver?

Scimmia · 2024-01-01 20:44:39

just install mesa, it'll remove mesa-amber.

Gabachin · 2024-01-01 21:03:27

Got it. Can you explain what happened to my system in the first place? After an update, I got a blank sddm screen, and was not able to start my wm with xinit or startx. I removed the xf86-video-intel drivers (and now the mesa-amber) and installed mesa. Now my system runs as expected. I thought removal of the xf86-video-intel drivers would make the system automatically fall back on modesetting. And mesa is just a set of (open-source) drivers for Intel graphics. What does this have to do with the original problem?

Scimmia · 2024-01-01 21:05:23

You should have never had xf86-video-intel installed in the first place. Ever since the legacy drivers were split off into mesa-amber, your system has been broken and falling back to software rendering. The mesa update broke software rendering, so it went from broken to broken and unusable.

Gabachin · 2024-01-01 21:37:53

Yes, ok, that makes sense. My system is a vanilla Arch setup, that I installed following the Arch Wiki. I think I needed the xf86-video-intel for xbacklight with i3wm, the wm I chose. I wonder if the offending driver was also the reason I could never get a stable system with the zen kernel, always has to use lts. Anyway, marking as solved.
