Hi everyone

So today, I upgraded my Arch Linux with pacman -Syu, there was a kernel update. After rebooting, my display got broken, text or foot got broken :

Any idea ?

X or Wayland? Card(s) and driver(s)? Journal and/or Xorg log? What else was in the upgrade?

Please read How To Ask Questions The Smart Way and update your post with relevant information...

Hi,

I use X.org, my GPU is Intel GMA 950 with the driver xf86-video-intel. There were in the upgrade libutil-linux, git, util-linux, pciutils and sdl2. And btw I see no Xorg log in /var/log/.

I had thought of the idea of reinstalling Intel drivers and Xorg, but the error occurs before I startx, worth to give it a try ?

No, this is the framebuffer. Do you use any "video" kernel parameter?
Is this a UEFI or BIOS setup? Bootmanager?

Passing "nomodeset" will likely get you a usable console (but no X11)?

No, I don't think I use any video kernel parameter, as I installed Intel drivers and never changed settings.
My PC is BIOS, and my bootmanager is GRUB

So, I added i915.modeset=0 to my Kernel mode setting, now I don't have those weird text glitches anymore (but no X11 yeah)

Time to dump the log of a "broken" boot.
You can also try to pass "i915.enable_fbc=0" (but keep modesetting enabled)
Also try to establish an X11 autostart to see what happens when the ddx driver (modesetting or intel?) takes control.

Please also try intel_iommu=off

Nayko · 2017-09-28 20:22:56

Here are the boot logs : https://pastebin.com/e4UM4W0p
And why not, the logs of Xorg : https://pastebin.com/6fRNGgpf
I'll try to establish an X11 autostart tomorrow.

Btw, intel-iommu=off didn't fixed it

Not of a boot w/ i915.modeset=0 - that's pointless.

journalctl -b-1

Thus my complaint

Ah missed context read w/ as meaning with not without.

Nayko · 2017-09-28 20:41:11

Sorry, my bad

Here are the broken boot logs : https://pastebin.com/tG0hKt6i

Is it okay now ? (sorry if I don't understand, english is not my native language)

https://bugs.freedesktop.org/show_bug.cgi?id=102929 looks similar to one of the errors.
