After yesterday's upgrade, I can't start xorg with startx. I got a black screen, and my monitor says no signal detected.
I use a nvidia GTX 750 Ti video card, and use startx to run dwm window manager.
Message from startx says simpledrm_dri.so is missing, but pacman -F shows no one provides this so file.

Switching back to linux-lts and nvidia-lts fixed the issue.
Still don't know why non-lts version doesn't work.

You'll have to provide xorg log and/or system journal for the affected boot.
You're not interested in simpledrm_dri, likely the nvidia kernel module wasn't installed/loaded, possibly nouveau in the initrams.
Hard to tell based on essentially no relevant data.

@seth, thank you for your reply.
Here's the xorg log when I couldn't start xorg.

You're running on the nvidia chip, there's an output attached and you get
[     9.338] (II) NVIDIA(0): Virtual screen size determined to be 2560 x 1440
…
[     9.707] (II) NVIDIA(0): Setting mode "DFP-0:nvidia-auto-select"Then half a second later this happens:
[    10.178] (II) NVIDIA(0): Setting mode "NULL"Do you use xinit/startx?
Please post your xinitrc.
To mitigate this try (and I cannot believe I'm now writing this) nvidia-xconfig to generate a static server config and put that into /etc/X11/xorg.conf

I think I've found this cause.
I use a script to set up my monitor. And the script uses xrandr -q | grep connected to check the number of connected monitors.
On the 6.1.43-1-lts kernel,  the command returns the correct answer:
HDMI-0 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mmBut on the 6.4.8-arch1-1 kernel, the command returns:
HDMI-0 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
None-1-1 connected (normal left inverted right x axis y axis)There's a "None-1-1" monitor that doesn't actually exit.  Not sure if this is a bug in the 6.4 kernel.
And this "None-1-1" made my script crazy and caused the issue.

That's the simpledrm … nuisance.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
