Pbm manifests when killing X-session, either on exit, logout, or reboot. I can chvt between X and a console using function keys or chvt #, but when shutting down, logging out of X or rebooting, instead of automatically switching to console 1 (from console 7, when rebooting/shutting down) or presenting the slim login screen (when logging out), screen remains on console 7 with current screen w/lines all over it (as if attempting to set LCD screen to a bad video mode) and keyboard and mouse LOCKED (-must powercycle!-). Non-critical when shutting down/rebooting, as it'll still reboot, but critical if trying to logout and return to slim login screen (doesn't!). Pbm manifests the same regardless of window-manager selected at login.

Successful workaround is to map logout and shutdown/reboot to scripts that first do a"chvt 1" and sleep for 2 seconds BEFORE logging out/shutting down/rebooting, etc. In short, I must do a"chvt" away from the X session BEFORE killing X!!! Suspend and resume work properly w/o this workaround. I'm on an HP Elitebook 8440p w/Intel integrated graphics (see inxi below).

Following things tried to no avail:
choosing different window-manager
rebuilding initramfs manually
kernel line (adding): nomodeset; kernel line: vga=355;
xorg.conf: option"LinearFramebuffer""true", option"ReprobeOutputs""true", option"XuMC""false";
slim.conf (adding to"xserver_arguments" line:" -keeptty -novtswitch".

Current configs:
slash etc slash initramfs-tools/modules:
intel_agp
i915


I can rule out hardware, as I have another Antix install on same hardware w/o issue, only"difference" must be either the fact that the failing distro is set up as a dual-boot from Win7 (initial boot screen is Win-7 bootloader into separate /boot partition - vfat) or some other configuration file difference that I can't find!

Related warnings in dmesg (startup)

Any experts that can shed some light on this?

Thanks!

Are you using Debian Testing? What desktop are you using? Your inxi does nt show anything. Nor does it show if you are using systemd or sysvinit

I'm using Debian Testing with sysvinit (nosystemd) desktop: slim, doesn't matter which windowmanager:

and / etsy / defaults/console-setup has (but I haven't tried changing that yet, but have doubts it would affect anything, would it?):

ACTIVE_CONSOLES="/dev/tty[1-6]"

I had this same problem and found the solution.
I use xserver AccelMethod UXA for Ironlake not SNA (for Sandy Lake or newer).

Thanks, hobbyist,

That indeed seems to have FIXED it! Only thing is that I did lose a bit of graphic speed (glxgears went from reaching 10K to now reaching approx 8.5K. The weird thing is that SNA worked find on my older Dell D620 (also w/Intel graphics). One thing I did have to add back, in order to be able to see the console messages during shutdown or reboot was put the"-keeptty -novtswitch" options back onto my slim.conf file,"xserver_arguments" line!

My debate now (with myself) is whether to keep my"chvt 1; sleep 2" workaround scripts in my shutdown/reboot/quit buttons/menus (and Ctrl/Alt/Backspace sequence disabled) in order to have the higher SNA throughput or keep it as-is now w/UXA!

Ok, here's the deal. Problem manifested in kernel upgrade from liquorix v4.4-6.dmz.1 (Last known Good version) - going back to that version resolves issue. There's no current Antix kernel above this version, so no way to test there. Problem also only seems to manifest when undocked (no external monitor attached). I've decided to go back to SNA for the improved video performance and use my workarounds when exiting X and undocked (add"chvt 1; sleep 2" to scripts that exit the window-manager - either to log out, shut down, or reboot) until and if a new kernel version comes along that resolves this regression. I will just avoid Ctrl+Alt+Backspace whilst undocked. It can also be ruled out that this is in any way an Antix issue rather it is upstream!

This seems to be fixed in recent 4.6 kernels.
