Bug Description

I upgraded my xubuntu 13.10 to 14.04 recently. When I turn the monitor off and on, it only shows "no input signal". I have to restart x to bring it back to work. This never happened on 13.10.
Booting from xubuntu 14.04 livecd or a clean installion of xubuntu 14.04 gives the same problem.
I tried xset dpms force off/suspend/standby, the monitor works fine after resuming. So i suppose it's not dpms to blame.
My graphics card is Intel HD4600 and my monitor is Dell UP3214Q. The monitor is connected with a displayport cable.
Enable or disable the displayport 1.2 setting of the monitor doesn't change anything.
This issue does not occurs on another computer (with nVidia gfx card+Dell U2713HM+DVI cable)

Reinstall 13.10 solved the problem.

Following Straximus's lead (https://bugs.launchpad.net/mythbuntu/+bug/1308105/comments/18), I downgraded to the xfce4-settings package from Saucy. I left the machines allow all weekend long, and this morning the video on both machines worked as expected.

There is a regression bug between xfce4-settings 4.11.0-1ubuntu1 (saucy) and 4.11.2-1ubuntu2 (trusty).

just tried xfce4-settings_4.11.3-0ubuntu1 recently made available on launchpad.
I can report that it does *not* solve this issue so I've rolled back again to xfce4-settings_4.11.0-1ubuntu1 and will continue to wait.

Is this report a duplicate of bug 1308105?

This issue is possibly specific to DisplayPort, and not just a duplicate of bug #1308105.

I have just upgraded my monitor, and due to higher screen resolution, was forced to change from DVI (and a KVM) to DisplayPort.

The monitor will NOT sleep, and attempting to workaround by power-off/on (when unneeded) hits THIS bug. Setting the monitor to sleep (eg. powersave timer) also triggers THIS bug. The ONLY fix being to power cycle the PC.

However, the most common workaround I have found generally says: "Don't use DisplayPort, use DVI Dual-Link".

ALSO, if bug 1308105 is the cause, where is the fix? When will it arrive?

This appears to be a xfce4 regression bug, and specific to DisplayPort ..

david6, I suggest that you file a separate report on the Xfce bug tracker and help with resolving the issue. We may then remove the duplicate status of this report.

If you have a question specifically related to bug 1308105, please forward it accordingly.

This affects me too. I have a GTX 660 connected to a HP LP2475w monitor with Ubuntu Desktop 14.04 over a DisplayPort cable. Switch the monitor off and on again, and it says no signal. I have to reboot to get the machine back. This makes DisplayPort unusable. The problem goes away with a DVI cable. See my question here:

I think the duplicate status is wrong. I see this behaviour with a DisplayPort monitor (and no other screens connected) on standard Ubuntu Desktop 14.04 - I am not running Mythbuntu and I don't have xfce4-settings installed. See my post above.

This affects me too. I have a Radeon HD 7970/8970 OEM / R9 280X and the display is a Samsung U28D590D. Using an HDMI cable works perfectly. Using DisplayPort makes the display be disconnected when light-locker kicks in. I have to manually reconfigure the display until it shows me images again. I do notice that the display receives some sort of signal when I active my computer. But it shows no image and then goes back to idle.

I have a seconday monitor connected via DVI and that monitor keeps working perfectly.

Siwtching manually to tty1 before switching the display on again solves this sometimes but is not reliable and not a usable solution.

Same problem here - running on a Core i3-2100T with Intel HD Graphics 2000 on 14.04 LTS. After switching off the monitor connected via DisplayPort only a reboot or a "sudo service lightdm restart" will get the screen back. It does not happen with DVI.

Bugs Bunny (bugsbunny-) wrote :

I also have the problem with the blank screen after monitor power cycle.
I'm running Xubuntu 14.04 on a Dell Optiplex 7010 with a Radeon HD 7570 VGA card that is attached to an LG ultrawide monitor (2560x1080) via DisplayPort, my desktop is XFCE4.

As this problem is very annoying I googled quite a bit and found this and that but nothing really helped.
I also stumbled upon the fact that there must be something weird with xfsettingsd: at least under some circumstances this daemon was said to be responsible for leaving a blank screen while crashing when the monitor gets switched on.

So I had a look whether this is also true in my situation but xfsettingsd was still happily running while the screen refused to come back on.

Don't know exactly why (maybe the anger at xfsettingsd to fail somewhere ;-)) but I just killed the running instance and was completely stumped to see the display turning on again ...

Even stranger is: I tried that several times - monitor switch off/on - and suddenly it wouldn't lead to a blank screen any more =:-O

Only thing that could happen then was a flickering display; but I could get rid of that by a forced dpms cycle (via xset dpms force off/on with a "sleep 1" in between).

When killed with a hangup (SIGHUP/1) xfsettingsd will normally be restarted automatically (by XFCE session handling I guess); if it doesn't you might recognize this by different window decorations or so, just start it manually then.

Hopefully my experiences help someone else, and maybe I have the time sometimes to dig into the problem ...

I'm also experiencing this with an NVidia card and a Samsung s27a850 monitor. Can someone who is knowledgable about the software advise about what a fix would require?

For me, the main symptoms are
1) pressing power button on monitor causes Ubuntu to drop the screen from list of displays, rearranging my meticulously positioned windows.
2) monitor doesn't go to sleep when 2 other monitors go to sleep. It stays on indefinitely.

I had this both on Elementary OS and Xubuntu. I've got an AMD card and tried using additional drivers, so I selected one of the video drivers, in my case I picked the following option in eOS 'Using Video driver for the AMD graphics accelerators from fglrx-updates (proprietary)'.

This solved the problem of not being able to consistently use a secondary monitor which was using a display port. However I'm now not able to screenshot anything as it only shows the wallpaper now.

I experienced this problem when I switched from DVI to Display-port due to purchase of a a new monitor "LG 34UC97" running a resolution of 3440x1440.
- (K)Ubuntu version is 15.10
- drivers installed are "plain" out of the box, more or less beside the usual "apt-get upgrade".
- GPU is definetly a "nvidia geforce gtx 750 TI", however ubuntu reports it as a "GTX 970". My previous ubuntu (?) reported the card correctly.
- nvidia drivers are the one installed via kubuntu, namely 352.63. I tried to "handinstall" the latest from nvidia but that screwed up so I rolled back.

1) The problem occurs in the following cases:
a) user must be logged in. screen-log or not, does not matter.
b) display-port attached monitor is switched off (e.g. over night).
c) monitor is switched on but complains now about not receiving a display.

2) The problem does NOT occur when:
a) no user is logged in, e.g. only kdm/lightdm login screen is there.
b) on windows 10 ( I have installed parallel)

I assume the GPU switches off its "service" via display-port to the monitor once the monitor is switched off.
However it does not resume "service" when the monitor comes back again.

The problem cannot be so difficult to solve as it does not happen in 2b) and especially in 2a) mentioned before.

Are there any consolidated updates and solutions for the topic?

thanks.

I'm also experiencing this problem.
I had the following configuration:

MacbookPro 8,1 13" laptop (2011)
Dell UltraSharp U2715H LED monitor
Ubuntu 14.04
Mini-Displayport (computer) to Displayport (monitor) connector

I had those annoying 2-3 second unpredictable intermittent blanks, driving me crazy.

I used to have the problem with a Dell 24in monitor 2408WFP as well (same computer).
I figured it was something to do with the monitor and bought the new monitor (since we needed a second one anyhow).

But the problem persisted with the U2715H.

I figured it might be something to do with the computer (anecdotally it seemed to occur more often when it heats up, though I'm not certain).
I needed to change that old computer anyhow, so I bought an Intel NUC to replace the laptop.

New configuration:
Intel NUC NUC6i5SYH w/ 32GM of RAM
Dell UltraSharp U2715H LED monitor
Ubuntu 16.04
Mini-Displayport (computer) to Displayport (monitor) connector (same cable).

Lo and behold... same problem!

All that leaves is
- the cable, or
- the software.

Now I just got myself an HDMI to HDMI cable to the Intel NUC.
Just began testing. Hopefully the problem will be gone.

Happy to test again later if someone fixes the bug--contact me <email address hidden>

I am also connected to a Sony TV, but I am using the DVI output with HDMI to DVI cable.

Switching to the virtual terminal 1 with alt+f1 works and I can restart lightdm from there and everything works, once I do.

Laptop: HP Zbook with Intel and NVidia graphics on Ubuntu 16.04 latest.
Using Intel graphics, since NVidia doesn't work correctly on boot (another bug...)

What I understood from presentation, is:
- Intel graphics card don't work with DisplayPort 1.2 and 4k monitors, because there is no bandwidth?
- So, I should make my NVidia card working on my laptop ... HP Zbook 15

Every now and then when the monitor falls into power saving mode, when I wake it up, it shows a 'entering power saving mode' and blacks out. When I try to access the monitor menu, it says there is no signal, and so does my connected Cintiq. Only a reboot helps.

Same issue with Dell P4317Q GTX 960 with nvidia-370 drivers on Ubuntu 16.04.

One thing that I can be sure is, it is only happening when you connect the screen with display port. It happens with or without nvidia drivers. Looks like it is linux kernel or ubuntu desktop issues.

The screen blacks out occasionally and comes up on immediately. I hope below helps.
