#Changing TTYs leads to a kernel panic on those TTYs only

Hello. A month or so ago, i noticed that suddenly, Ctrl+Alt+F1 isn't my main tty, and that now the tty2 is the main one. I almost don't have any problems with it.

The main thing i have noticed is, whenever I change the tty with CTRL+ALT+F1 or any F key at all, i get the blinking underscore which should indicate a kernel panic. However, I can just go back to the default tty (tty2) and continue like this never happened.

Also, things like emacsclient -c test.txt don't work and produce an output like ERROR: Display :0 can't be opened.

Also, please gzip the log before uploading as Discord's download bandwidth is suboptimal.

I can trigger it now and then upload the log

#

Be right back

#

I can't get journal to output for last 2 minutes

#

I ran it as journalctl -S -2m, also tried journalctl -S 2m and it doesn't work, even though man systemd.time says that it understands minutes, minute, min, m for minute parsing

I see one error related to sddm: Jul 14 00:33:38 arch sddm[469]: Authentication error: SDDM::Auth::ERROR_INTERNAL "Process crashed"

But i will check journal now to see if same error happens everytime

I just triggered the tty switching again and looked into the journal ran by sudo

I think these are the relevant messages

#

It did use TTY1 before all these things started happening

#

Since the weird things started happening, my main TTY is TTY2

#

Though SDDM works perfectly on it

#

However, i see nothing except /dev/sdb2 clean ... something and a blinking underscore when i try to change to any other tty

#

I changed the tty at 17:15 and those messages were the only ones in the journal that started at that time

#

Also there were no messages after those

#

I mean none of the ttys except the tty2 can be used now

#

Also, so far i have only had another weird problem with emacsclient that says that it can't find a display

#

And before all this that worked okay

Waiting for data... (^X or interrupt to abort)

#

Running it with sudo produces results. Should have known

Try to see if it is a driver issue, especially if you are using a proprietary Nvidia driver.

Hope others can help. I'm offline.
