Xorg logs

same issue

I'm also experiencing this bug with Fedora 29 and the MATE desktop. If I select Gnome when logging in, there is no problem.

It logs the same "Failed to get GBM bo for flip to new front" / "present flip failed" message pair 20x per second.

I see this on multiple computers, one with an Intel i7-6770HQ and one with an Intel i5-6260U.

One more detail: both systems are using Intel integrated graphics with the i915 driver.

Can confirm this on xfwm and marco on f29. Both WMs now use the X Present Extension by default. Seems only Xorg 1.20 with modesetting DDX is affected.

Workarounds :

1) Switch to the intel DDX driver.

2) Disable page-flipping in the modesetting DDX or Xorg.

3) Start xfwm with "--vblank=glx". This disables XPresent support.

Any examples how to modify config files?

This prevent me to login to Xfce /etc/X11/xorg.conf.d/90-disable-page-flipping.conf:

Section "Device"
	Identifier "devname"
	Driver "modesetting"
	Option "PageFlip" off
EndSection

I found ~/.config/xfce4/xfwm4/ directory but don't know what to do next.

Running Mate on Fedora 29 and this bug is filling up my drive.
Video is Intel 915

Is there a work around that works. Putting an xorg.conf in /etc/X11
prevents X from starting.

Yes, I found something here:
https://community.parrotsec.org/t/self-reseting-to-loging-screen/3368/4
except that in may case the path is slightly different:
MATE menu>System>Prefrences>Look and Feel>Windows>General tab>Enable software compositing window manager checkbox.

Unticking the checkbox stops the message flood immediately.
Other side effects I could observe:
- only icons instead of thumbnail pictures when doing Alt-Tab window switching,
- the newly introduced icon flash-up when starting applications by the panel icons is not performed.

No other adverse effects in the past couple of hours in my environment.

That PageFlip business didn't work for me either.

Thanks. That did it for me as well.

But I am still hoping for an Intel915 fix for this.

After all, I managed to turn off page flipping.
The trick was to hit upon the correct device identifier.
My conf file is:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "PageFlip" "off"
EndSection

Now, I don't know which workaround is better: turn off page flipping or disable the compositing window manager, I voted for the former.

BTW, I don't have installed the following packages on my system mentioned in this bug report:
xorg-x11-drv-modesetting (actually no such package exists in the Fedora repos)
xorg-x11-drv-intel

I do have only this:
xorg-x11-server-Xorg

The modesetting driver is now part of Xorg server:
$ rpm -qf /usr/lib64/xorg/modules/drivers/modesetting_drv.so 
xorg-x11-server-Xorg-1.20.3-2.fc29.x86_64

Also, switching to the intel DDX driver via the following conf file stops the error messages for me (I'm on xfwm 4.13):

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
EndSection

Kwin, compton and xfwm4 with "--vblank=glx" doesn't produce such errors with default modesetting.

So I guess this is related to the Present extension and the modesetting driver. Should this bug be fired against xorg-x11-server-Xorg instead?

Yes, I suspect that no maintainer may pay any attention because of reference to this nonexistent component:
Component: 	xorg-x11-drv-modesetting (Show other bugs)

xorg-x11-server-Xorg would be better.
Who can change that? The original submitter?

I'm getting the same error message with modesetting driver. However, I'm forced to use the modesetting driver due to bug https://bugs.freedesktop.org/show_bug.cgi?id=109187 . Otherwise I get blank output on the external display (driven by nVidia GPU).

$ rpm -qf /usr/lib64/xorg/modules/drivers/modesetting_drv.so

The "Enable software compositing window manager checkbox" hack from comment 8 stops those messages but those fancy 3D-shadows around the windows disappeared.

I had the same problem with i915 on an Acer Switch 10 notebook runnig MATE, the above setting solved the log spam problem, not sure about any visual implications yet.

I have the same problem on an Intel HD Graphics 630 (i915 driver) and xfce4.

This is causing a 1.4 kilobyte/second (= 120 megabytes/day) append traffic to $HOME/.local/share/xorg/Xorg.0.log.  This problem is thus an i/o & storage consumption one too.

Can the driver be changed to rate limit the offending messages, and/or stop trying the failing flip operation at some point.  Seems like that would be a fairly simple fix, to make the symptom less painful.

For now I've resorted to running a locally compiled modesetting_drv.so on my laptop where those error messages have just been commented out.

There is an upstream merge request for this: https://gitlab.freedesktop.org/xorg/xserver/merge_requests/131

Me too (so I get on the cc)

David, could you pull the proposed fix into Fedora for downstream testing?

Same issue here
Fedora 29 with xfce4
Intel HD Graphics 520

Same issue here with XFCE Fedora 29, Intel i915 driver.  Not sure when the Xorg messages started, but I got involved when my display started freezing (mouse OK) after updating to Kernel 5.0.4.  Ctl-Alt F2 to a virtual terminal and Ctl-Alt F1 back fixes it, for a time.  I noticed the log spam while troubleshooting. Unchecking "Enable display compositing" in Window Manager Tweaks (from the XFCE Settings) stops the log messages.  I don't know yet whether it solves the screen freezes...

Just want to clarify ... "Ctl-Alt F2 to a virtual terminal and Ctl-Alt F1 back fixes it, for a time." fixes the frozen screen.  Not sure yet if the screen freezing has anything to do with this bug report.

Thanks for the hint, also here unchecking "Enable display compositing" finally stopped the log messages.

same problem here, apart the log messages, since kernel 5.0.x the screen freezes randomly every 10-30 minutes (xfce4
with xorg), sometimes ctrl-alt-f2 ctrl-alt-f1 works to unfreeze, sometimes not

Still happening on XFCE Fedora 30, Intel i915 driver, kernel 5.1.5-300.fc30.x86_64.

I have been getting the modeset failed messages since updating from Fedora 28 to Fedora 30. I use the MATE desktop. I just found this bug report.
Unchecking the "Enable software compositing window manager" checkbox seems to have helped. Thanks to whomever discovered that.

I still get some other messages, but much less frequently.

Hopefully this will be back-ported to xorg 1.20 branch. Otherwise default compositing in MATE and Xfce is broken since f29.

FEDORA-2019-84694484f4 (1.20.5) fixes the log spam with the MATE desktop in Fedora 30 for me.

xorg-x11-server-1.20.5-3.fc30 has been pushed to the Fedora 30 testing repository. If problems still persist, please make note of it in this bug report.

Will there be a build for F29?

> Will there be a build for F29?

I agree, we really need this for F29.  I notice it's not in the testing branch yet.  Upstream has fixed the issue with 1.20, and it's in testing for F30, so hopefully it's just a matter of time.  Wondering what the process is...? Is it an automatic thing (build for F29) or does it require a champion? https://bodhi.fedoraproject.org/users/ofourdan :) ?

xorg-x11-server-1.20.5-3.fc30 has been pushed to the Fedora 30 stable repository. If problems still persist, please make note of it in this bug report.

I concur with the utility of this improvement for Fedora 29.

Unfortunately, I think we'll have to revert that change, it is causing regressions (bug 1725499)

Is it possible to not spam logs at least then?

Maybe not: https://gitlab.freedesktop.org/xorg/xserver/issues/842#note_186635 .

Please apply this patch to FC29.
