 Posted: Mon Feb 27, 2023 6:15 pm Post subject: [Solved] X doesn't start with new 6.1.12 kernel |
 |
|
Hi.
Just updated kernel to 6.1.12. And rebuilt nvidia-drivers-390.157 against new kernel too. After reboot X doesn't start with famous error message:
| Code: | | parse_vt_settings cannot open /dev/tty0 (permission denied) |
id shows I'm in video and wheel groups.
elogind and dbus are started and running.
What's wrong with new kernel? Why xorg-server works with old kernel and doesn't work with new one?
How new kernel breaks permissions to /dev/tty0?
| Code: | x11-drivers/nvidia-drivers-390.157::gentoo was built with the following:
USE="X driver static-libs tools -dist-kernel -persistenced" ABI_X86="32 (64)" |
| Code: | x11-base/xorg-server-21.1.7::gentoo was built with the following:
USE="udev xorg -debug -elogind -minimal (-selinux) -suid -systemd -test -unwind -xcsecurity -xephyr -xnest -xvfb" ABI_X86="(64)"
FEATURES="sfperms pid-sandbox config-protect-if-modified usersandbox ebuild-locks unknown-features-warn assume-digests qa-unresolved-soname-deps unmerge-logs distlocks multilib-strict merge-sync binpkg-dostrip news ipc-sandbox unmerge-orphans sandbox preserve-libs binpkg-docompress userpriv protect-owned binpkg-logs network-sandbox parallel-fetch fixlafiles strict xattr buildpkg-live userfetch usersync" |
Added: old kernel 5.15.80 still works fine with these nvidia-drivers and xorg-server

Blind_Sniper,
Which display manager do you use? How do you start X?
Can you test starting X via startx? |

Yes, it is a NVIDIA ...  (sorry; no offence; we all love nvidia drivers)
Please try this at first: Disable this
| Code: | | CONFIG_SYSFB_SIMPLEFB=y |
and maybe also
| Code: | | CONFIG_DRM_SIMPLEDRM=y |
(if it was enabled). |

Using sddm.
startx doesn't work too, with the same error message
@pietinger
They both (CONFIG_SYSFB_SIMPLEFB and CONFIG_DRM_SIMPLEDRM) not set

Blind_Sniper,
Please try the following:
Disable XDDM service and login as a normal user.
Make sure you are the owner of TTY device, group is 'tty', it's a character device and mode is 0600:
| Code: | | $ ls -l /dev/tty$(tty | sed 's|^.*\([0-9]\+\)$|\1|') |
Run this command to start X:
| Code: | | $ xinit $(which xterm) -geometry =80x65+10+10 -fn 8x13 -j -fg white -bg navy -- :$(tty | sed 's|/dev/tty||') vt$(tty | sed 's|/dev/tty||') |
This command will skip your ~/.xinitrc and start new X session with single xterm window.
It will display xterm with blue background.
Type 'exit' in xtrem window to exit this X session.
Please provide ~/.local/share/xorg/Xorg.$(tty | sed 's|/dev/tty||').log |

With 5.15.80 kernel:
| Code: | ls -l /dev/tty$(tty | sed 's|^.*\([0-9]\+\)$|\1|')
crw--w---- 1 root tty 4, 0 Feb 28 2023 /dev/tty0 |
and X works, nothing wrong with permissions. I think it should be the same permissions for 6.1.12 kernel and X should be happy with it too, why should I change permissions?
| Code: | | ~/.local/share/xorg/Xorg.$(tty | sed 's|/dev/tty||').log |
no such file

You are not supposed to change permissions of your TTY device manually.

That Xorg.log file is created when you run 'xinit' from text console as a non-root user and server option ':$(tty | sed 's|/dev/tty||')' is specified.
With kernel 6.1.12, could you try this sequence?:
1) Disable XDDM service.
2) Login as restricted (non-root) user into text-mode shell (bash for example).
3) Verify TTY permissions, using 'ls' command from previous post. Please provide output.
4) Start X session via 'xinit' command from previous post.
5) Locate and share Xorg.log. Make sure timestamp matches the time you started 'xinit'. Location of Xorg.log is either here:
| Code: | | ~/.local/share/xorg/ |
or here:

crw------- 1 user tty 4, 1 Feb 28 19:34 /dev/tty1 |
xdm stopped. When running xinit
| Code: | | xinit $(which xterm) -geometry =80x65+10+10 -fn 8x13 -j -fg white -bg navy -- :$(tty | sed 's|/dev/tty||') vt$(tty | sed 's|/dev/tty||') |
screen goes blank for few seconds then reports that no screen found and server terminated successfully

Blind_Sniper,
You have to add user with uid=1000 to 'input' group:
| Code: | | $ sudo usermod --append --groups input user |
Replace 'user' with actual user login name.
Then logout, re-login, run 'xinit' as before, then post Xorg.log, please. |

Try this (Xorg server should not be running when you do this):
| Code: | $ sudo mv -iv /usr/lib64/xorg/modules/extensions/libglx.so /usr/lib64/xorg/modules/extensions/libglx.so.orig
$ sudo cp -aiv /usr/lib64/xorg/modules/extensions/libglx.so.390.157 /usr/lib64/xorg/modules/extensions/libglx.so.390.157.orig
$ sudo mv -iv /usr/lib64/xorg/modules/extensions/libglx.so.390.157 /usr/lib64/xorg/modules/extensions/libglx.so |
Then run 'xinit' as before and provide new Xorg.log, please. |

@ukky
thanks for your effort
The problem occured due to kernel. New version requeres some config options changing : CONFIG_FB_SIMPLE should be disabled and FB_VESA should be activated (CONFIG_FB_VESA=y). And there should be CONFIG_DRM_KMS_HELPER enabled as module (if not set).
After rebuildig kernel the problem has gone.
