View Full Version : [xubuntu] upgrade 13.10 to 14.04 black screen HDMI/ TV 'No signal'

I've updated Xubuntu from 13.10 to 14.04 and it all went well. Reboot the system and login-screen. I filled out my password and voila 14.04 up and running. But now comes the but; The TV switch to No singal after a while and it wouldn't switch back on by mouse or keyboard. I've got a Ivy-Bridge i3 running Intel Graphics connected to a Philips LCD TV by HDMI (HDMI2).


I can access terminal by switch to TTYx switching back to F7 is black again.
When TV switch itself of after 3 Hours and I switch TV back on, no way it will see a signal from system running Xubuntu.
Reinstalled Xserver and inteldrivers and set permissions back again. still same problem 'No signal'
Set kernel parameters 'nomodeset' and 'acpi'_something. doesn't make a difference. TV goes to 'No signal'
Set Power Managament Monitor to 'Never' same problem and fiddled with other power management settings
'I read a topic here about Display Manager. so a give the following command a try;
sudo services lightdm restart bam. Back in Login-screen so TV switched back on. What the heck!


Somebody a clue?

that command is used to restart your x server. i am assuming your tv isn't sending a signal back to xubuntu so xubuntu thinks it can go to sleep. are you sure you disabled all the power saving options within your xorg? look into DPMS

Probably you mean my monitor can go to sleep. I set time to system go into sleep to 'never'. I also thicked off settings-->Settings Manager-->Power Manager --> general tab --> uncheck "Monitor power management control". Apparently DPMS is still enabled, see console output. One think I don't understand about my TV is not sending a signal; Why did this setup work with Xubuntu 12.10, 13.04 and 13.10?

By the way I can't find xorg.conf. it's not in /etc/X11/ and not in /usr/share/X11/

Anybody?!

xorg.conf isn't created by the system. if you need to do something non-standard than you would create an xorg.conf file and put it within /etc/X11/

I can not say why it worked in previous ubuntu versions. i just noticed you're using some acpi or other in your kernel boot line, please remove that as well as the nomodeset, did you have either of those in your previous ubuntu installs when you say it was working?

@dannyboy79 I've tested with these kernel-parameters, but it didn't work. The behavior was still the same, so I removed these entries. So you think creating a custom xorg.conf will solve the problem?

I could dfind how to control my display with xset. Arch Linux Forum give the correct syntax. Now I can switch my TV on and off in cli;


root@htpc:~# xset -display :0 dpms force off
root@htpc:~# xset -display :0 dpms force on


hmm one step further.
<Edit>
I've let Xorg generate a xorg.conf file. but first stopped display Manager;


sudo Xorg -configure

The move it from yopur home directory to etc/X11/
Now I've add extra entries in /etc/X11/xorg.conf;


Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
Option "dpms" "false"
EndSection

Let see how this goes!

The previous settings don't work. This morning I switched on my TV and bamm 'no signal' I've restart Display Manager and know the xset command doesn't work;


raymond@htpc:~#sudo xset -display :0 q
Invalid MIT-MAGIC-COOKIE-1 keyxset: unable to open display ":0"

Hi.
First of all - you shouldn't do anything related to you current screen/user under root. So do not use sudo.
Second:
1. Do you use only one monitor? Or it is a laptop with Monitor/TV connected?
2. To see a user current settings you can execute in xterm: "xset -q". Look for DPMS. Also there is "screen saver" there.
3. Execute in xterm: "xrandr --verbose". It shows other video settings.


P.S.
You know, I remembered that I had the same result one long time ago.
I will try to explain what happened: I turned dpms to ON, and then I turned monitor power off (I was not going to use my comp again soon). After some time I came back and found that I can't woke up my monitor. I thought that video chip disable video output because monitor was turned off. Since then I never turn monitor off - and never had this again.
May be in your case it is some kind of "save energy" function in your TV. You can for example execute "glxgear" in console and live it for a while.

Hi,

I use one monitor and that's my TV. Xubuntu functions as a htpc.

xset -q will give unable to open display "";


raymond@htpc:~$ xset -q

Then you can: "xrandr -d :0.0 --verbose.

Also please then your TV will disconnect again, change TTYx login with your name and password and type: "xrandr -d :0.0 --verbose". It should show you information about connectors.

Yours doesn't have "*current". This might means that somehow X11 forgets about proper resolution and therefore your TV can't display anything.

Please, type and execute in console under current user:
xrandr -d :0.0 --output HDMI2 --mode 1920x1080
That should make mode "1920x1080" "*current"

yep you're right! It also has the Gamma, Brightness and dimensions entries (mm) in output like you have. Okay and know what? What is a permanent fix? Bye the way I'm still running with the custom xorg.conf in /etc/X11/. If it got no use I'll ditch it.

What I suggest to do next.
Rename xorg.conf to xorg_conf
Make new directory in root console: mkdir /etc/X11/xorg.conf.d
Make new file in root console: touch /etc/X11/xorg.conf.d/10-monitor.conf
And put the follow to 10-monitor.conf as root:


Section "Monitor"
Identifier "HDMI2"
Option "PreferredMode" "1920x1080"
EndSection

Section "Device"
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "HDMI2"
EndSection

Section "ServerLayout"
Identifier "Main Layout"
Screen "Screen0"
EndSection


Then you have to logout and login. Then execute in user console: "xrandr -d :0.0 --verbose". I hope that you will see "*current" in modeset.
If something will go wrong - change TTY login and rename "10-monitor.conf" to "10-monitor_conf", and then reboot because I do not know how to restart X on different TTY.

What happened. Can you describe what exactly happened?
Did you just left you machine for a while or what?
What was in /var/log/Xorg.0.log.

Lets play with it - when next time you notice that your screen is out, change TTY and check /var/log/Xorg.0.log.
After this, type "xrandr -d :0.0 --output HDMI2 --mode 1920x1080", then change tty to 7 and check if you can see picture.

Can you please, show us part with " intel(0): Modeline ..." or something like this, you will add it to config.

Yep I left it on for a while but thisa morning I got the same. I thought "Well okay I didn't reboot but a restart of lightdm". So I gave xubuntu a reboot. When I came back from biking I turned on the TV and bammm again 'No signal'. So then I went out to fiddle something myself. I read in an article http://samuelmartin.wordpress.com/2012/05/29/enabling-resolutions-in-ubuntu-12-04-lubuntu-12-04/ you can insert 'Modeline' in Section "Monitor". Modeline is;


raymond@htpc:~$ gtf 1920 1080 60

# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync

I've add that to Section "Monitor" in 10-monitor.conf
So now 10-monitor.conf looks like this;


raymond@htpc:~$ cat /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
Identifier "HDMI2"
#Option "PreferredMode" "1920x1080_60.00"

No. You should take modeline from Xorg.0.log:
Modeline "1920x1080" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

So, monitor section will be:

Section "Monitor"
Identifier "HDMI2"
Modeline "1920x1080_m" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync
Option "PreferredMode" "1920x1080_m"
EndSection

I didn't. I got it from output of command 'gtf 1920 1080 60' see first dumped code-snippet in my previous post. Strange is Xorg.0.log has entries all with '+hsync' for 1920x1080. gtf says '-hsync' So modeline-entry is manual adding a resolution-setting.
Edit;
I've add the PrefferedMode option again and after a reboot it's current profile is the Modeline-entry. I kept the one that was dumped with gtf;


1920x1080_M (0x4a) 172.8MHz -HSync +VSync *current +preferred
h: width 1920 start 2040 end 2248 total 2576 skew 0 clock 67.1KHz
v: height 1080 start 1081 end 1084 total 1118 clock 60.0Hz

OK.
It has to be tested.

Nope it doesn't! Same behaviour! '*current' is gone again for 1920x1080_M. Switching to TV or PS3 attached to resp. HDMI1 and HDMI3 give signal.

I had a similar problem and i fixed it this way: (its just a workaround, not actual fix)


$ cat /etc/udev/rules.d/hdmi.rules
KERNEL=="card0", ACTION=="change", RUN+="/home/.../fix.sh"

and the script:


$ cat /home/.../fix.sh
#!/bin/bash
export XAUTHORITY="/home/.../.Xauthority"
export DISPLAY=":0.0"
xrandr --output HDMI1 --mode "1920x1080_60.00"

Of course you need to change card0, HDMI1 and "1920x1080_60.00" to match your setup.

Script doesn't work. I figured out how to check if system sees HDMI-port is connected or not. I physically removed HDMI-cable and system gives right output;


raymond@htpc:~$ cat /sys/class/drm/card0/card0-HDMI-A-2/status
connected
raymond@htpc:~$ cat /sys/class/drm/card0/card0-HDMI-A-2/status
disconnected
raymond@htpc:~$ cat /sys/class/drm/card0/card0-HDMI-A-2/status
connected


Now I'm trying to figure out how I can test if script is even running.

This thread and Raymond's experience is exactly, even to the point of what has not worked, is what I have been struggling with also. I just wanted to make note of this that it is not an isolated Raymond-only type of issue. I am using xubuntu as an htpc as well, upgraded to 14.04, and have to restart my display manager to get my X back...again, exactly like Raymond.

Nice somebody with same issue. And that's why there are fora:D

[EDIT] Script works! the piped command ts in shell-script underneath will add timestamp to entries in logfile.

Raymond:

I found the following bug on launchpad:

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1308105

I know that this refers specifically to nvidia cards so it may or may not apply to you, but I wanted to mention that the last comment on this ticket states stopping xfsettingsd as a workaround. This did indeed work for me.

Raymond_Uphoff
May 8th, 2014, 01:32 PM
Hi debdiesel,

Do you every time this happens manually stop xfsettingsd or do you have some kind of script? Did you file a bug-report?

debdiesel
May 9th, 2014, 10:52 PM
Raymond:

I just unchecked xfsettingsd from starting in the XFCE sessions dialog. This will prevent xfsettingsd from starting when xfce first starts.

I have this exact problem in Mythbuntu 14.04. At first I thought the screensaver wasn't waking, but it turns out all I have to do to recreate the problem is turn the TV off then on again. I will try the script when I have time to make sure I understand it.

I have the same problem too. xubuntu 14.04 installed as upgrade from 13.10. Monitor is connected via HDMI. Everytime I power off the monitor and turn it back on again, the screen does not wake up.

Thanks for the help, I have installed the scripts and the bash script works to modify with xrandr when I run the script, but putting the new rule in /etc/udev/rules.d/hdmi.rules does not seem to do it automatically. So I can only recover the monitor if I happen to have terminal open and can run the bash script sight unseen. Any ideas why adding the hdmi.rules to /etc/udev/rules.d/ is not automatically fixing the problem, when the current setting is dropped.

I have tried killing xfsettingsd, and this does fix it, but I would rather not have this not running as my desktop is then very ugly!

Edit: Trying to figure out what is going wrong.

Here is my rules

$ cat /etc/udev/rules.d/hdmi.rules
KERNEL=="card0", SUBSYSTEM=="drm", ACTION=="change", RUN+="/home/neil/bin/hdmi_workaround.sh"


here is what happens when I monitor what happens when I switch off the monitor

$ sudo udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[7106.206266] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm)
UDEV [7106.231214] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm)

So the kernel is registering the change, and I can run the script /home/neil/bin/hdmi_workaround.sh and it works to bring the monitor back, but it does not seem to happen automatically.

First you should check to which device your machine is connected. The script is an example. configure it according to your hardware.

EDIT: @nsummers; who is the owner of hdmi.rules? Make it root when it isn't.

I have configured the script to my hardware. I know it works as I can run the script in a terminal when the screen is blank and get the hdmi to work again. Permissions and ownership seem ok.
$ ls -l /etc/udev/rules.d/
-rw-r--r-- 1 root root 94 Jun 14 17:23 hdmi.rules

EDIT:
It is very strange, now it works, but not the first time. What I mean is that the screen is blank when I turn on the monitor, but if I turn it off and on again a second time it come back (but if I check xrandr it does not report the *current settings properly, but it still comes back).

What I do have now is that I started xfsettingsd in a terminal, and when I get this error I get the report

The program 'xfsettingsd' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRRCrtc (invalid Crtc parameter)'.
(Details: serial 1021 error_code 148 request_code 140 minor_code 21)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

I could do all of this and get the backtrace, but does anyone have a link to the a bug report for xfsettingsd?

Not sure if this is the same problem, but I had a "No Signal" on my Onkyo amp (HDMI) and a blank screen (obviously) after power cycling the screen/amp..

This is what worked for me..
(about disabling HotplugEvents worked for me!)...

I edited /etc/X11/xorg.conf and added the line: Option "UseHotplugEvents" "false" to the Device section



The tip from here: http://www.gossamer-threads.com/lists/mythtv/users/570769

create a configuration with nvidia-xconfig if you haven't done so
then add to the "Device" section:
Option "UseHotplugEvents" "false"


For what it's worth: I'm using this as a HTPC, so I'm running the latest mythbuntu with lightdm, on an AsRock ION-3D.. I uninstalled the ubuntu nvidia drivers, and ran the latest proprietary nvidia driver install. I have also disabled all screensavers, and display power management.

So for me, 14.04 is running well now!

I've updated Xubuntu from 13.10 to 14.04 and it all went well. Reboot the system and login-screen. I filled out my password and voila 14.04 up and running. But now comes the but; The TV switch to No singal after a while and it wouldn't switch back on by mouse or keyboard. I've got a Ivy-Bridge i3 running Intel Graphics connected to a Philips LCD TV by HDMI

I had same issuses with a HDMI-Switcher. I solved this by creating a xorg.conf and added ' Option "Hotplug" "false" ' in the device section. I'm also using the Intel driver.

Yours, Klaus

It could also be caused by this bug: https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1313539
Following comment #7 and downgrading xfce4-settings to saucy's package fixed it on my mythbuntu 14.04 machine without touching xorg.conf.
