    Re: HOWTO: Setup vncserver + gdm on Ubuntu 8.04 Desktop

    I followed this guide, and also have the problem with an empty screen with the X cursor. I even tried to enable HonorIndirect without any luck.

    All the necessary changes are made, it just won't work. Does anybody here have a clue on how to fix this?

    I cant remember where I found this fix but it soved my grey screen problem. Took me hours of trawling to find it.

    Edit /etc/modprobe.d/aliases and find the line containing

    alias net-pf-10 ipv6

    and replace ipv6 with off.
    After reboot everything should work!




    Hope this helps

    I have a problem like you, I tried to fix this by:

    Edit /etc/gdm/gdm.conf-custom
    Code:
    sudo vim /etc/gdm/gdm.conf-custom
    (try another editor if you can't use the vim editor)

    find:
    Code:
    [daemon]
    add after:
    Code:
    RemoteGreeter=/usr/lib/gdm/gdmgreeter
    find:
    Code:
    [security]
    add after:
    Code:
    AllowRemoteRoot=true
    AllowRoot=true
    find:
    Code:
    [xdmcp]
    add after:
    Code:
    Enable=true
    restart gdm
    Code:
    sudo /etc/init.d/gdm restart
    Hope this helps
    Sorry for my bad English .

    However how would one keep the session alive so that you could continue to run programs on the remote machine while closing your VNC viewer?

    Basically set wait = yes
    See man xinetd somewhere near the end about this.
    Thanks for the tutorial. Everything has worked great, expect I wanted to have the session I started to be resumable, so I could start a session, start a couple programs, close vnc, then later open vnc and manage the programs.

    However, with wait = yes I am not able to open vnc at all. It just gives the error "The connection closed unexpectedly. Do you wish to attempt to reconnect to localhost:5901". If I change it back to wait = no then I am able to load vnc again (but session aren't resumable.)

    I had the same gray screen or connection refused when trying to connect to my Xubuntu laptop from my Ubuntu desktop.

    I undid everything in this how-to and successfully did this:

    Hope this helps out a few gray-screen victims!

    Re: HOWTO: Setup vncserver + gdm on Ubuntu 8.04 Desktop

    As far as the "Theme Switching", or more accurately the Gnome settings-daemon recursively crashing then giving up, I have stumbled upon this page.

    http://www.francescosantini.com/inde...=linux&lang=en

    Will let you know what happens.

I have seen this happen while scrolling through a file browser window as well. I have tried removing the gnome2

    Any help or advice in fixing this little issue would be much appreciated, thanks!

    EDIT: As I was typing this the gnome settings daemon crashed, reporting that it had restarted too many times. I will search on this topic and see if I can find a solution.

    EDIT2: It looks like there is an issue with the gnome-settings-daemon keyboard.

    I am experiencing the theme-switching as well and have been googling for 3 days now and this was the best related page/post (however also without a solution) I could find thus far. I was wondering (seeing it has been a year and I am on 9.04) whether this is solved yet, or if someone found a work around. Thanks in advance guys!

    Just found this url stating it is probably a bug: https://bugs.launchpad.net/ubuntu/+s...on/+bug/199245

    Anyone able to verify / give advice anyway?
