Second monitor not working anymore

pallagiannini · 2019-10-06 09:07:25

I have an update Archlinux system and kernel on my HP probook laptop with NVIDIA graphic card and running MATE DE (Xorg)
Last week I was using a second monitor without any flaws, but now I have switched monitor and since then I have done some full system upgrade and now when I try to switch to the second monitor it says "Could not set the configuration for CRTC 64" on the notifications area and nothing happens.
if I switch to GNOME the second monitor isn't working as well.
if I switch to tty2 I could see the text shell mirrored on the second monitor.

$ lspci -k | grep -A 2 -E "(VGA|3D)"

Xrandr and the MATE GUI "DIsplays" settings manager find the monitor but trying to enabling it doesn't work.

I don't see anything particularly interesting in the logs you posted. Then again, I know only a little about video driver troubleshooting. Do you have any custom xorg configurations in /etc/X11 or /etc/X11/xorg.conf.d? Have you had any kernel upgrades or module upgrades? I know Mesa has been updated recently, have you rebooted in the last 2 weeks?

The steps I would take:

Remove the monitor, reboot, reattach the monitor, test.
Try a different monitor. You said you switched monitors and did a system upgrade. The upgrade may not be the issue, it may be the monitor itself.
Try the Nvidia proprietary drivers. See if it's an issue with the mesa drivers, or something else.

I lied. At the bottom of xorg.log.0 there's a handful of errors. They might be relevant. Perhaps the monitor in question does not support the options you're trying to apply to it.

Try those and post the exact output (if any and if they don't work)

xrandr --output eDP-1 --auto --output HDMI-1 --auto
xrandr --output eDP-1 --auto --output HDMI-1 --mode 1920x1080i --rate 60

I have rebooted my computer after upgrade and before trying the second monitor.

Tried many times removing monitor and reattaching and removing, rebooting, retrying, no changes: second monitor still failing.
Unfortunately I don't have another monitor to test if the problem is this monitor, I will try next week if the problem will not be solved.
I tried nvidia drivers and blacklisted nouveau, set up the kernel parameters and run the autoconfiguration as suggested in the wiki but that broke also my first display so now I have removed the nvidia driver and restored all as before.

 $ nvidia-xconfig

I tried also using optimus manager to switch to the integrated INTEL gpu but with no noticeable effects, I still have optimus right now.

I don't have personalized Xorg, this is the content of

 $ ls /etc/X11/xorg.conf.d/
10-optimus-manager.conf

 ls /etc/X11/Xsession.d/
60xbrlapi

 ls /etc/X11/xinit/xinitrc.d/ 
40-libcanberra-gtk-module.sh  50-systemd-user.sh  80-appmenu-gtk-module

The 2 commands suggested by seth return no output and didn't resolve the issue (tryed with root and with normal user)

xrandr --output eDP-1 --auto --output HDMI-1 --auto
xrandr --output eDP-1 --auto --output HDMI-1 --mode 1920x1080i --rate 60

What's the updated "xrandr -q" output after those calls?
The DDC modelines are a bit weird, esp. some VESA modes (800x600, 1024x768) should be there - is there some sort of adapter involved?

Can you

xrandr --output HDMI-1 --mode 640x480

?

What about:

xrandr --output eDP-1 --off --output HDMI-1 --auto; sleep 5; xrandr --output eDP-1 --auto --output HDMI-1 --auto

(run this as one command; if things fail you should still have a visiable output after 5 seconds - nevertheless prepare to lose all outputs and the need to kill the X11 server and all your programs with it!)

Now I get video image on second monitor, but the notification "Could not set the configuration for CRTC 64" is still there every time I try to switch configuration, also I can only mirror the screen but not have expanded monitor configuration or second monitor only.
this is xrandr -q now:

-------------------------
I figured out how to change the configurations, there are some glitches (when I switch the image is all messy, 1280x720 is the only config that doesn't broke Xorg on both displays when switching and the image on second monitor is zoomed and shifted) but I can do almost everything I could before.

Does it work better if you switch to xf86-video-intel ?

I changed the adapter but without any changes, yesterday I tried with another monitor and it worked quite well without giving me all the errors gives me the 'buggy' second monitor, so I think that this is a monitor-related issue.
It's strange that I have no problem at all with windows pc when trying to use the 'buggy' second monitor.

I guess it's because of the interlaced mode. What monitor is it specifically (vendor/model)?
You could try to add a progressive modeline: https://wiki.archlinux.org/index.php/Xr … esolutions

Thank you very much, as I got time from university I will follow these resources to solve the problem!

The only monitor I have experienced this issue is the SONY KDL-46V2000

Do I have to add the monitor model name to the OP to make it easier for other users find my post if they have same issue or is it better to edit the title as well?

seth · 2019-10-15 13:04:41

The interwebz says the panel has a 1366x768 (WXGA) resolution, so the adapter is creating some nonsense resolution (1080i has a slightly lower clock than WXGA but that doesn't mean the panel support this - i guess the adapter just guesses some fitting resolution)
=> add a WXGA resolution and select that. Should™ work. Does windows drive the output at that resolution?
