Solved Black screen when exiting DE

B

bxbzq

Hi,

System: 13.2-release-p2
DE: xfce
Graphics driver: nvidia-driver 535.86.05

startx works fine, but when log out from DE to console, I got completely black screen, no keyboard cursor, no mouse pointer. The NumLock light can be turned on and off though. Switching between consoles doesn't make a difference. The only thing I can do is to log into system using ssh and reboot the system. Reading Xorg.log doesn't give me any clue, looks normal there.

Thanks for any help.
 
Was a long time ago this happened on my box, AFAIR also with an Nvidia card onboard. There was something with the X server not releasing the display, and the solution was pretty simple.

Try the things in this thread and using vt instead of sc console.

Solved - Black screen on exit from xorg server

I have a brand new install with nothing but Xorg installed (Acer Aspire laptop with an Intel GM4500 video card). On startx, Xwindows starts but is very dark (almost black). I have found that if I execute setpci -s 00:02.0 F4.B=60 before or after startx the screen will brighten up to be visible...

I don't need to add the kern.vty=vt in /boot/loader.conf, because the vt is the default setting in my case.
 
Try adding the following to /boot/loader.conf. You will have to reboot.

hw.vga.textmode="1"

I assume you are loading nvidia-modeset.ko and nvidia.ko from rc.conf? You may not need to explicitly add nvidia.ko (it may be a dependency of nvidia-modeset).

Doesn't work.

In my case, only nvidia-modeset is specified in /etc/rc.conf.
 
Do you have a login manager? When you log out it goes back to login display.

Are you switching to a virtual console through the F1 keys?
 
Have you tried other DEs or a plain window manager? That would rule out anything hanging up and stopping the exit process.
You say you can ssh in; have you run top or something to see what is running, perhaps the xfce process is still running and you can kill -9 as root?
 
I don't know if this will help or not...
I also get a black screen (albeit with a banner : "set monitor resolution ..."). My monitor resolution - 3840x2160. I have GTX 1650. It didn't happen before (with my old GTX 950, even with the same Nvidia's driver). Because of this, I could not turn off the computer right way. And couldn't switch to another tty (even if I could, I could not type anything there from the keyboard). I did not solve the problem, but I found a workaround (suitable for me).
I did the following in /boot/loader.conf
kern.vty=vt
hw.vga.textmode=0
efi_max_resolution="1280x1024"
# efi_max_resolution="3840x2160" - it doesn't work

After this, I could switch between ttys (and use the keyboard there).
Now, before exiting DE, I switch to another tty (Ctrl-Alt-F3), run shutdown -p +1m there, return to DE (Alt-F9) and exit DE, get a black screen (at this point I can't switch to another tty) and wait for the system shutdown...(but it's not necessary, of course, I could run shutdown from DE without switching ttys)

Edit: I run DE with startx
Edit 2: In my case it does not depend on DE (I tried Gnome, CDE, xfce) the result is the same
Edit 3: I'm getting the same behavior on Debian 11 (where I'm using X / Gnome, and Nvidia's driver). But on Debian 12 everything works fine (there I'm using Wayland / Gnome, and nouveau/NV166). On Debian, I don't use startx, and I don't need to run shutdown manually , since there is a "PowerOff" button in Gnome.

Thanks for the tip. From top I can see xfce not running when log out X.
Maybe I'll try other DEs if the issue gives troubles me too much.

If you look at top while xfce is running you do see xfce?
Double check "save session on logout"; it's been a while since I've run xfce, but I thought it asked about saving session. Maybe "don't save session"?
I've also run into issues where you have things in the autostart and then save session you get multiple instances of the same thing running which could cause issues.

Yes, xfce and others app running under X.

Doesn't help. The issue persists.
 
Another thing you can try is that it could possibly be on twm as with my experience it is a black screen i believe you need to open the terminal by using a keyboard shortcut or left click on the screen.

I recommend if you have check demsg or message log to see if there's anything there.
 
Could it be the "Module tmpfs failed to register: 17"?
In /var/log/messages, there are these lines highlighted:
Code:

Could it be the "Module tmpfs failed to register: 17"?
In /var/log/messages, there are these lines highlighted:
Code:

If you are running GENERIC [1] kernel on amd64, you already have tmpfs functionality in the kernel itself.
So kldload'ing tmpfs.ko via /boot/loader.conf or /etc/rc.conf[.local], it should fail. It is quite normal.

But if you are using MINIMAL built yourself (or custem kernel config including /usr/src/sys/amd64/conf/MINIMAL with minimum modifications), failing to kldload tmpfs.ko is abnormal.

I'm running generic kernel, but I have no settings in /etc/rc.conf or /boot/loader.conf to load tmpfs.ko. I mount tmpfs via /etc/fstab.
 
For your info:
I have the line below in my /etc/fstab.
Limiting size mount option below 5G caused build failure of lang/gcc12 with OPTION LTO_BOOTSTRAP (default for amd64), so I have stopped limiting.
And with this configuration, I never saw tmpfs.ko kldload'ed.

Code: 
tmpfs    /tmp    tmpfs    rw,mode=1777    0    0


Note that /etc/defaults/rc.conf has the line below. So if, for example, you have any script which configures mfs (or tmpfs itself directly) with explicit kldload, you could be bitten by it (just a warning each, though),

Code: 
mfs_type="auto"    # "md", "tmpfs", "auto" to prefer tmpfs with md as fallback

For me, searching "tmpfs" on /etc/rc.d/ and /usr/local/etc/rc.d/, as examples, resulted as below.

Code: 
% rg "tmpfs" /etc/rc.d/
/etc/rc.d/linux
79:             linux_mount tmpfs "${_emul_path}/dev/shm" -o nocover,mode=1777

/etc/rc.d/dhclient
53:     # e.g. if /var/run is a tmpfs

/etc/rc.d/tmp
35:desc="Configure tmpfs"

/etc/rc.d/var_run
38:     df -ttmpfs /var/run > /dev/null 2>&1 &&
43:     df -ttmpfs /var/run > /dev/null 2>&1 &&
% rg "tmpfs" /usr/local/etc/rc.d/ 
/usr/local/etc/rc.d/samba_server
54:    # Make sure we have our RUNDIR, even if it's on a tmpfs

No explicit kldload tmpfs found.
 
SirDice said:
tmpfs(5) is included with the GENERIC kernel.

GENERIC « conf « amd64 « sys - src - FreeBSD source tree

cgit.freebsd.org cgit.freebsd.org

Besides already being included, many modules will auto-load if accessed. In other words, calling tmpfs in fstab automagically loads the module if it's not already loaded.
Click to expand...
Exactly. :)
So as bxbzq alrealy stated using GENERIC, any errors related with kldload/kldunload of tmpfs logged in /var/log/messages should be the results of explicit (not implicit) kldload / kldunload.
 
I overlooked the line of tmpfs_load="YES" in /boot/loader.conf. Now it is removed. Rebooting the system and the message "Module tmpfs failed to register: 17" goes away.

But, the black screen issue still persists.

% rg "tmpfs" /etc/rc.d/ /etc/rc.d/linux 79: linux_mount tmpfs "${_emul_path}/dev/shm" -o nocover,mode=1777 /etc/rc.d/dhclient 53: # e.g. if /var/run is a tmpfs /etc/rc.d/tmp 35:desc="Configure tmpfs" /etc/rc.d/var_run 38: df -ttmpfs /var/run > /dev/null 2>&1 && 43: df -ttmpfs /var/run > /dev/null 2>&1 && % rg "tmpfs" /usr/local/etc/rc.d/ /usr/local/etc/rc.d/samba_server 54: # Make sure we have our RUNDIR, even if it's on a tmpfs
No explicit kldload tmpfs found.

I overlooked the line of tmpfs_load="YES" in /boot/loader.conf. Now it is removed. Rebooting the system and the message "Module tmpfs failed to register: 17" goes away.

But, the black screen issue still persists.

How do you start Xfce in your .xinitrc or something equivalent?
I'm not using Xfce for a long time, but last time I tried it, I had lines below in my .xinitrc for startx.

export WINDOWMANAGER=XFce4 exec startxfce4 --with-ck-launch

And previously to the above, used below.

export WINDOWMANAGER=XFce4 exec ck-launch-session startxfce4

I've never encountered such a black screen on exit at the moments.

Currently, I'm using MATE as my desktop environment.

export WINDOWMANAGER=Mate LIBOVERLAY_SCROLLBAR=0 exec dbus-launch --exit-with-session ck-launch-session mate-session

Never encountering black screen on exit issues.

Note that all non-DE-specific lines are ommitted above.

Just tried. No magic.
I used to have an old amd graphics card on this machine and xfce worked just fine. If I remember it correctly, ever since I replaced it with a new nvidia RTX4070, the black screen issue has been around. I suspect it is the nvidia driver related. But a nvidia-driver re-installation or upgrade didn't make a difference.
 
Are you UEFI booting or using CSM to boot the machine? The reason I ask is because they use different graphics calls for the console (UEFI GOP vs. VBE).

I have a system EUFI booting with an RTX3080 and I can switch between X and console without issues.

If you don't know how the system booted, look at the machdep.bootmethod sysctl, it will say "UEFI" or "BIOS".
 
I don't have an answer for you, just a little bit more evidence I can add.

I had been using a very old Apple Cinema Display with no issues. I recently switched to a Samsung UR59C and have been seeing the exact same behavior you describe.

I have no idea what's causing it. Maybe it's 1080p vs 4k. Maybe it's that the Apple display had a USB bus, and the Samsung doesn't. Maybe it's something completely unrelated.

It's UEFI booting.
