[Solved] TTY Screen freeze on login with new hardware

Hi,

I've migrated my install to new hardware and everything is working as it should, except that my screen freezes when I reach the TTY login prompt.
I can login and run commands just fine, like for example starting up my window manager (dwm), X11 works fine.

I copied this installation over from my old drive using

rsync -qaHAXS

, regenerated intiramfs, updated fstab and re-installed bootloader.
I've tried booting with ibt=off grub kernel parameters.

dmesg: http://ix.io/4bPq

journalctl: http://ix.io/4bPs

Not too sure what to do, so I will post my dmesg and journalctl output here.
Assist is much appreciated.

Re: [Solved] TTY Screen freeze on login with new hardware

You also have an integrated GPU running that grabs the framebuffer device and there was a recent change in linux that then prevents the nvidia driver from allocating it's own driver (since they don't have a terminal framebuffer)

If you have no use for the integrated GPU, disable it in your UEFI/BIOS or if you don't find any such option, blacklist i915 ( you can do so on the kernel commandline with module.blacklist=i915 )

Re: [Solved] TTY Screen freeze on login with new hardware

Hi,

I tried blacklisting i915 in /etc/default/grub and /etc/modprobe.d/blacklist.conf but it still gets loaded.
I'd like to keep it on in BIOS.

$ grep i915 /etc/default/grub 
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 module.blacklist=i915"

$ dmesg | grep i915

$ cat /etc/modprobe.d/blacklist.conf
blacklist i915

Did I do something wrong?

Try changing module.blacklist=i915 to module_blacklist=i915.  If the result is still the same try in /etc/modprobe.d/blacklist.conf

install i915 /usr/bin/true

Re: [Solved] TTY Screen freeze on login with new hardware

Hi,

I added

install i915 /usr/bin/true

to /etc/modprobe.d/blacklist.conf and now TTY works fine.

Thanks for the assistance, marking as solved.
