evince and eog broken on remote sessions (X, NX, x2go and VNC)

I doubt the hanging is due to libgrip or utouch in general. utouch-geis should notice that there is not an XInput 2.2 capable server and immediately stop initialization. Please try running evince under gdb to see if it really is hung up in utouch while starting up. Until then, I'm moving this to the evince package.

Looks like evince got stuck in libgrip/libutouch-geis
Attached gdb trace

Impacts sessions running over Real VNC too.

Status changed to 'Confirmed' because the bug affects multiple users.

closing the evince part but keeping it so users who ran into the issue can maybe find this report, the issue seems to be an utouch-geis one

I've found that downgrading to libutouch-geis (2.1.2-0ubuntu4) from oneiric resolves the issue.

$ wget http://mirror.anl.gov/pub/ubuntu//pool/main/u/utouch-geis/libutouch-geis1_2.1.2-0ubuntu4_amd64.deb
$ sudo dpkg -i libutouch-geis1_2.1.2-0ubuntu4_amd64.deb
$ echo "libutouch-geis1 hold" | sudo dpkg --set-selections

FYI: Just built utouch-geis1 (2.2.9-0ubuntu4) from lp:utouch-geis/precise and the issue was _not_ resolved. Still took ~50 seconds for evince to load, compared to under a second with libutouch-geis1 (2.1.2-0ubuntu4) from Oneiric.

Yes, the patch is missing the key line that fixes the problem, I'm reverting it right now.

If it helps, I'm attaching the result of starting evince with Geis debugging enabled on precise over RealVNC.

Hello! Can you please make sure this bug has Test Case and Regression Potential, per the procedure outlined here:

https://wiki.ubuntu.com/StableReleaseUpdates

Otherwise it will be difficult to verify the fix. I will leave the upload in the upload queue for now.

Thanks!

I have deferred creating an SRU since new information came to light after uploading to the queue. I will continue the SRU process after additional investigation.

I've rejected the existing SRU from the precise-proposed queue based on your previous comment; please feel free to upload again after you've finished investigating.

This bug should be re-opened, as the fix merged in https://code.launchpad.net/~bregma/utouch-geis/lp-997630/+merge/106886 does not actually address the issue. In particular, the assumption that the DBUS_SESSION_BUS_ADDRESS is unset is inaccurate, as show in comment #9.

This bug was fixed in the package utouch-geis - 2.2.10-0ubuntu1

Note that this bug is still not considered completely fixed in Ubuntu 12.04 (precise pangolin).

Ubuntu 12.04.
I am having similar problems with evince when logging in remotely using xrdp. Opening any file with evince shows a blank window and the blank window takes a long time to close (a couple of minutes). It also displays the messages
(evince:18278): GRIP-WARNING **: failed to determine device types
(evince:18278): GRIP-WARNING **: Failed to initialize gesture manager.
Running evince with the -w option works. How do I set up Ubuntu so that opening a file from nautilus uses the -w option?

I have purged utouch* and the problem still persists.

@ferro: Yes, but I bet you still have libutouch-geis installed. (libevince depends on libgrip0 which depends on libutouch-geis).

@chasedouglas & @bregma:

I've looked into this problem some more and the fix should be relatively trivial. I'll attempt to briefly describe the cause of the error, outline a simple solution, and will attach a patch that can be applied to the utouch-geis 2.2.10 source which fixes the problem for me.

The cause of the delay is that `_geis_wait_for_init` attempts to wait a full 5 seconds (GEIS_DEFAULT_INIT_TIMEOUT) or until the Geis backend is initialized. In the event of a failure, i.e., when no backend can be initialized, the 5 second waiting period is still observed. To fix this bug, we need only signal the failure of the initialization process so we can abort from `_geis_wait_for_init` immediately.

To do so, I propose the following changes:
1) Add a new GeisState, GEIS_STATE_ERROR
2) Set geis->state to GEIS_STATE_ERROR whenever no backend can be initialized and we are out of fallbacks.
3) Check for geis->state == GEIS_STATE_ERROR in _geis_wait_for_init and abort.

I should additionally mention that the logic in the above patch might not be flawless --- i.e., the addition of the else clause in _input_event_handler might be a bit off -- but the overall theme of the patch should point you in the correct direction.

The attachment "libutouch-geis-state-error.patch" of this bug report has been identified as being a patch. The ubuntu-reviewers team has been subscribed to the bug report so that they can review the patch. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-reviewers team please also unsubscribe the team from this bug report.

Patch do not apply to the source for armel architecture.
The code of geis.c is slightly different, but I am not a programmer so I do not know how to fix it
I attach the file that I get with "apt-get source libutouch-geis1"

@chasedouglas: Thanks! I've backported the change to utouch-geis 2.2.9 and successfully built and tested the patch in a PPA. https://launchpad.net/~brad-froehle/+archive/utouch-geis

Thanks Chase, do you guys plan to SRU that fix as well?

Hi Seb,

Yes, an SRU is in progress. It will hopefully be uploaded shortly after the precise-proposed freeze is lifted.

Hello Emanuele, or anyone else affected,

Accepted geis into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/geis/2.2.9.1-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

My issue was solved after upgrading to the new libgrip0 (and hence libgeis1, libgrail5, libframe6) from precise-proposed.

Thanks!

$ apt-cache policy libgrip0
libgrip0:
  Installed: 0.3.5-0ubuntu1~12.04.1

        400 http://us.archive.ubuntu.com/ubuntu/ precise-proposed/main amd64 Packages

I can also confirm that the proposed update fixes this bug.

To verify the fix I've started an EC2 instance with the official precise AMI, installed ubuntu-desktop and the relevant x2go packages. The bug was reproducible. After installing libgrip0 and its dependencies from precise-proposed the bug was not reproducible anymore.

Thanks,
  Emanuele

Hello Emanuele, or anyone else affected,

I've installed libgeis1 2.2.9.2-0ubuntu1 and can confirm that the proposed update does fix this bug (the slow startup of evince when the backend fails to initialize).

I don't run Unity, so I cannot comment on whether this version solves that particular regression.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

did I miss a step somewhere?

I can not able to relate why this bug is marked fixed????? It is certainly NOT fixed!
I use gnome2d desktop and it does not work.
On my terminal servers here it takes evince 45 s to start up - this is a show stopper.
ii libgeis1 2.2.9.2-0ubuntu1
ii libgrip0 0.3.5-0ubuntu1~12.04.1

For the record, `evince` seems to work OK if you pass it the `-w` (preview) flag.

If the root cause of this bug has been fixed, it isn't pushed to the stable repositories.

After upgrade to Saucy, the symptoms persist:

[4757284.068031] evince[6095]: segfault at 0 ip 00007ff85f446e10 sp 00007fff2a90b338 error 4 in libgeis.so.1.3.0[7ff85f440000+24000]

... and no segfault when passing "-w".

I can confirm that the bug is still present on Ubuntu 12.04.

After the update&upgrade, evince still takes a minute to start up, and it is unusable. Same GRIP-WARNING messages. Same version of libgeis and libgrip of post #38.

In Trusty (libgeis1 (2.2.16+13.10.20130919.4-0ubuntu2), libgrip0 (0.3.7+13.10.20130628-0ubuntu2)) the same behavior over x2go and xrdp (TigerVNC)
