Ok, here is a bit more info •6th Gen Intel(R) Core(TM) i7-6700HQ Quad Core Processor + NVIDIA GeForce GTX 950M 4GB Discrete Graphics. I have noticed that some of the screens that roll by have a much earlier date ( date time appears at the top of all of my screens). Is the server grabbing random memory from the video card? Is there any thing I can do to help pin-point the problem. [jerry@bigbox ~]$ gsettings list-recursively org.gnome.Vino org.gnome.Vino notify-on-connect true org.gnome.Vino alternative-port uint16 5900 org.gnome.Vino disable-background false org.gnome.Vino use-alternative-port false org.gnome.Vino icon-visibility 'client' org.gnome.Vino use-upnp false org.gnome.Vino view-only false org.gnome.Vino prompt-enabled false org.gnome.Vino disable-xdamage false org.gnome.Vino authentication-methods ['vnc'] org.gnome.Vino network-interface '' org.gnome.Vino require-encryption false org.gnome.Vino mailto '' org.gnome.Vino lock-screen-on-disconnect false org.gnome.Vino vnc-password 'dmljh5j' Closer examination of the erroroneous screens seems to reveal that they are simply replicas of earlier screens. eg: I booted into classical gnome and the trash can partially obscured the home folder. I dragged it down a bit. VNC from another machine will intermittantly display the original screen with the obscured home folder. another bit of evidence: The time is shown on the top of my gnome 3 screens. when connecting to the gnome 3 instance and the screens start appearing/disapearing some of the screens show older time stamps and over time these time stamps are not changing ( at least for 10~15 minutes ). I can use vncviewer to connect to a 32bit Fedora VM on my mac and it works fine. Hope this helps... Sigh, It appears that the GTX 950m does not even start on my laptop... [root@bigbox vgaswitcheroo]# cat switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 [root@bigbox vgaswitcheroo]# echoing ON to switch does not power on the card. echoing DDIS to switch generates a login loop when doing a logout/login sequence. Running glxgears shows [jerry@bigbox log]$ glxgears -info Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. GL_RENDERER = Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2) GL_VERSION = 3.0 Mesa 11.1.0 (git-525f3c2) So I suspect the VNC problem has nothing to do with nouveau... Close this puppy. Are you sure it isn't related? Because the problem went away after I installed NVidia driver (and blacklisted nouveau in the process). I have an "Optimus" system, the Nvidia card does not speak directly to the video ( at least that is what I understand ) and is not turned on. Using the tiger vnc server does not generate the same problem, but it has its own problems ( Evolution does not seem to be able to talk to gmail or apple mail ). Any hints on how to prevent nouveau from being loaded? Adding nouveau to /usr/lib/modprobe.d/dist-blacklist.conf does not seem to do the job... I would like to see it the VNC problem presists if the i915 intel driver is the only video driver loaded. Jerry Please follow article http://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/ , points 2.6.1 to 2.6.5 , if you are willing to. As usual, please have backups first :) Does this still happen on F24/Fedora 24? [my test laptop is busy currently] Fedora 24 appears to have fixed the problem :) Jerry This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
