Hi,

I've recently updated my system with intermittent reboots. After finishing
Code:

emerge -uDU --with-bdeps=y @world
dispatch-conf
revdep-rebuild
emerge @preserved-rebuild

my X server started with just a blank screen and with no input at all working (no switching to any virtual consoles possible anymore either, capslock doesn't turn on the light, ...). Only way out is shutting off manually. I'm kind of stumped since I don't see any of the usual red flags in Xorg.0.log or dmesg.
Info:
https://paste.pound-python.org/show/zx8td0tAV26q5Pmt8unW/
(binutils-libs stays in existing preserved libs after doing it again, no idea why).
Any ideas on how to get my system back to working?

emerge --info ? Which packages were updated ?

To solve the binutils problem, you can use the "eselect binutils" commands to enable the last version, and then uninstall binutils-2.25.1-r1.

Try rebuilding the x11 drivers for a start, this command should show what to rebuild.

Code:
qlist -I -C x11-drivers/


You may need to "emerge portage-utils" if you don't have it installed already


=== Edit ===

Generally something like the following list would be returned

Code:
x11-drivers/nvidia-drivers
x11-drivers/xf86-input-evdev
x11-drivers/xf86-input-keyboard
x11-drivers/xf86-input-mouse

Might be helpful to post the "/etc/X11/xorg.conf" file also

I've tried that, didn't help any. See paste for what got updated.

@Syl20
emerge --info is in the original paste (ctrl+f "cat ei"). Is there some way to show which packages were to be merged at some emerge?

EDIT:
I can still ssh into my machine after startx turns up blank with a non-blinking underscore at the top right. Killing the X server afterwards doesn't put me back into a virtual console.

That isn't the expected output. You should have something like this.

You can have a look on /var/log/emerge.log, for example.

I'm having the exact same problem today. I think I rebuilt the nouveau driver because I was getting some GL errors from xscreensaver. I get a black screen and no input. From the console everything looks fine. Xorg.0.log and sddm.log look perfect: they think they're running normally. I don't have an xorg.conf to post because I've been running without one for years.

I rebuilt all of X, including the drivers, with no change. I have absolutely no idea what to do at this point.

I have done world updates several times in the past few days without rebooting. I don't think anything related to X was on the update list, but I'm not positive. It's hard to read back through the emerge log file.

One possible clue is that if I kill the X server and run startx from a user console, I get a bunch of xterm windows and no input.

Alright, should've looked into the result of the pipe.

Due to the emerges being split over a few days, it's hard to get all the packages. But xf86-video-intel was among the updated packages. But I already did re-emerge that one.

I've searched a bit more and found mentions of X coming back up after waiting for 10 minutes with the frozen screen --- and it did work. But waiting 10 minutes simply for X to start up is kinda bad. I'm currently recompiling my kernel to see if that helps.

herpman,

The output of dmesg and the content of /var/log/Xorg.0.log after Xorg starts may provide a few pointers.

Did you try to reinstall the previous version ? Perhaps there's a bug with the new one.

dmesg got nothing new, Xorg.0.log got something new:

Not sure if the error about the stylus also came before the update, but it worked before and does now (it prints more errors though when used).

Kernel update failed due to my kernel apparently growing too large for my conservative USB drive, so I'll go try emerging the old xf86-video-intel next.

herpman,

I need the whole logs. I'm looking for things that are missing but should be present as well as any errors.
I can't see the things that are missing but should be present if you filter your logs.

Emerging the old xf86-video-intel didn't help either. I did get around to switching to another USB drive to get up to 4.9.16 from 4.4.6, but that doesn't help the startup time for X11 any.
