[Solved] limited ttys

Hello,

Today I have noticed a weird behavior , maybe caused by recent upgrade.When I try to switch to another TTY  I cannot swicth over
TTY3. XFCE session is running on TTY3.

rc-update show -v shows>
Code: [Select]
agetty |      default                           
          agetty.tty1 |      default                           
          agetty.tty2 |      default                           
          agetty.tty3 |      default                           
          agetty.tty4 |      default                           
          agetty.tty5 |      default                           
          agetty.tty6 |      default

It started just recently and I have no idea whats wrong. Maybe it is related with my previous post about a line which is displayed when I boot
Code: [Select]
/init: line 5: tmpfiles: not found

I humbly ask for help, this has never happened before.
I was thinking that I reinstall openrc, but before i would like to hear a advice from experts.

Thank you for any suggestions.

So in logs I have found following lines, if I understand well I have to create a symbolic links and add those to runlevels, but as you can see in first post, they are already added to runlevels at boot.
Code: [Select]

cat LOG.txt | grep  "agetty*"

So just a update, this is another hint i found
Code: [Select]
sudo rc-service agetty start
 * agetty cannot be started directly. You must create
 * symbolic links to it for the ports you want to start
 * agetty on and add those to the appropriate runlevels.
 * ERROR: agetty failed to start



So now I can only switch from TTY1 to TTY3 on which runs the XCFE session :(.

Re: limited ttys

So when I boot into LTS kernel I can switch into TTY1 - TTY5 and XFCE session runs on on TTY5.

When I boot into hardened kernel I can now boot now only into TTY1 and TTY2 where runs xfce sessions.

This is becoming strange, on gentoo wiki i have found this snippet
Code: [Select]
Start terminals as OpenRC services

Openrc-init does not use /etc/inittab, so the agetty processes for tty1 to tty6 will need to be started explicitly as services.

Create the links in /etc/init.d and add them to the default run level:
root #cd /etc/init.d
root #for n in `seq 1 6`; do ln -s agetty agetty.tty$n; rc-config add agetty.tty$n default; done



But in my /etc/init.d i already have those symlinks I guess
Code: [Select]
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty1 -> /etc/init.d/agetty
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty2 -> /etc/init.d/agetty
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty3 -> /etc/init.d/agetty
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty4 -> /etc/init.d/agetty
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty5 -> /etc/init.d/agetty
lrwxrwxrwx 1 root root    18 Sep  2 14:09 agetty.tty6 -> /etc/init.d/agetty



 and untill recently about one month ago everything run smoothly and.According to last I was logged on TTY7 , but frankly speaking I was not checking any other TTys, just a example.

Code: [Select]
tokaro   tty7         :0               Mon Jul 24 17:09 - crash (-30147+15:26)
tokaro   tty7         :0               Mon Jul 24 16:43 - 17:09  (00:25)
reboot   system boot  6.1.33-hardened1 Mon Jul 24 16:43 - 17:28  (00:44)

So some time ago I could switch from TTY1 - TTY7(xfce session)
and now only TTY1 - TTY2 on hardened kernel?

Hi Guys,

Brief update. After a month or so I booted my laptop. To my surprise I can switch between TTY1 - TTY6. On TTY7 blinks only cursor(dash _).
The X runs on TTY3 I do not know why some months ago it was running as expected on TTY7.
Code: [Select]
tokaro   tty7         :0               Tue May 23 20:12 - down   (01:44)
tokaro   tty7         :0               Tue May 23 19:56 - 20:12  (00:16)

tokaro   tty7         :0               Tue May 23 19:27 - 19:30  (00:02)
reboot   system boot  6.3.2-artix1-1   Tue May 23 19:27 - 21:57  (02:29)

When I booted with LTS kernel X was on TTY4, it seems that X chooses randomly the TTY.

The last command shows that the first time I have booted the X with different TTY was in july.  Might it be related to kernel version?
Code: [Select]
tokaro   tty5         :0               Sun Jul 30 16:51 - down   (04:23)

Thank you.

Hi,
 
So after installing several other DE I found out following. When i choose in SDDM(after booting) last used DE and log into it i get random number of TTYs activated.Sometimes X runs on TTY3 sometimes on TTY4 , when i want to switch with ctrl+alt+f5-f7, there is only a dash _ blinking, sometimes I can not switch above TTY4.
However when I log out from the firstly booted DE and return to SDDM welcome screen and choose other DE or WM , after logging in I have suddenly access to all default TTYs.
Here is a snippet from the LAST command
Code: [Select]
tokaro   tty7         :0               Sun Nov 19 21:56   still logged in
tokaro   pts/0        :0               Sun Nov 19 21:56 - 21:56  (00:00)
tokaro   tty7         :0               Sun Nov 19 21:56 - 21:56  (00:00)
tokaro   tty7         :0               Sun Nov 19 21:55 - 21:55  (00:00)
tokaro   tty4         :0               Sun Nov 19 21:54 - 21:55  (00:01)

As you can see, when i booted pc , and chose last used DE , I was signed in on TTY4, then log out and chose different DE and to my surprise I have access to all 7 TTYs, and X runs on TTY7 as expected.

So anybody , any idea what could be wrong? I have tried to trace back when it first started and it started sometime in July.
Could it be related to some problem with SSD? I use whole disk encryption with LVM and LUKS plus BTRFS.

Or the only solution is a fresh installation.

I have also tried to reinstall openrc and sddm.

Thanks for any suggestions.

I guess that is SDDM to blame. I personally doesn't use DM and DE, I have Openbox and semi-manual autostart of Xorg after console login with this in .bash_profile:
Code: [Select]
[[ -f ~/.bashrc ]] && . ~/.bashrc
if [[ -z "$DISPLAY" ]] && [[ $(tty) = /dev/tty1 ]]; then
  startx 2> $HOME/.log/.xsession-errors
  logout
fi
So Xorg session is always on tty1, and ttys 2-6 are working.

Some reference reading: https://wiki.gentoo.org/wiki/X_without_Display_Manager

Sorry for not being much help.

I also had some problems with switching tty's although not quite like your issue.
https://forum.artixlinux.org/index.php/topic,5664.msg35536.html#msg35536
It might be something to do with Xorg as it was not happening in Wayland, you could try installing Gnome and GDM (just as a temporary experiment) because using that desktop you can easily select either an Xorg or Wayland session from a drop down menu on the GDM login screen. When I bisected the kernel it was related to an unused section of code which suggests incorrect memory access is happening, I thought there must be a buffer overflow or some memory address error that can happen in relation to tty switching, perhaps due to a race condition as there is a random element to it's manifestation, and it affects 2 of my laptops with similar single thread speeds but not another with a different single thread speed. An E7470 has 4 cores and near identical performance to the unaffected M4500 with 8 cores, while the slightly affected older M4400 is slower overall but has a fast clock speed and only 2 cores. Due to the random element any of these findings could be coincidence though.

Edit:
This seems to be fixed for me now though, thanks to some update, I hadn't tried recently.

Hi,

So after some time playing I found a solution. I have uninstalled SDDM. I have installed GDM but I have encountered the same buggy behavior.

So I have installed Lightdm and it works.

After that I just did

rc-update add lightdm default

Thanks to all who tried to help.Maybe this will be usefull for others.
Merry Christmas
