    Installation of Mythbuntu freezes

    I'm new to Mythbuntu, but I had Knoppmyth running successfully for several months before the hard drive crashed. I decided to try Mythbuntu this time, but when I chose "Start or install Mythbuntu" I then see

    Starting lirc daemon:
    ...
    *running local boot scripts /etc/rc.local
    The screen flickers for a bit and then it bluescreens and says...
    Display server shut down 6 times in 90 seconds. It is likely something bad is going on. Waiting for 2 min before trying again on display :0.

    I was just starting to learn Linux when Knoppmyth crashed several months ago. I don't understand the problem. Can someone point me to a troubleshooting description for this?

    I can get my full hardware specs out in a while. But I think the most relevant item would be this is using my Olevia 32" TV connected through its VGA port as the monitor. I would have thought this would be fine. But do I need to yank the box out of the home theater and hook it up on my desk?

    Thanks.

    Try safe graphics mode.

    Re: Safe graphics mode didn't work either...

    I tried last night, same problem occurred. Any other thoughts?
    Thanks.

    Checkout /var/log/Xorg.0.log and /var/log/Xorg.0.log.old. See if they indicate why the X server is crashing.

    Re: Installation of Mythbuntu freezes

    So I did the ctrl+alt+F1 thing and nano'ed the 2 files you pointed me to. They were both like 1800 lines long. I scanned them and nothing jumped out at my newbie self. I searched them for 'error' and 'EE'. The only thing that came up was
    (EE) - AIGLX : Screen 0 is not DRI capable

    Does this suggest anything, or is there something else I should look for?

    Thanks.

    Yeah, you can try to disable DRI or AIGLX. See if that helps out. Google for how to do it.

    Re: error writing xorg.conf...

    I looked around and I couldn't decipher what people were saying about DRI. But it seemed like the prevailing opinion to disable AIGLX was to add the following section to /etx/X11/xorg.conf

    Section "ServerFlags"
    Option "AIGLX" "off"
    EndSection

    So I nanoed and added the above. When I tried to save it I got xorg.conf can't be written to, access denied. Then I tried saving it as xorg.conf.new and got the same error. Then I realized since this is all of a few seconds into the install routine, it is probably referring to the CD drive and not the HD.

    I have no idea how to go about altering the iso to burn on another CD. Plus the way it takes 50 tries for me to get something to work means I would have a nice coaster collection quick.

    Does anyone know if there is a way to disable DRI or AIGLX through a command line flag? I'm pretty far out of my realm of competence here.

    Thanks.

    Yeah edit it with

    sudo nano

    instead of just nano

    After doing this, issue a sudo /etc/init.d/gdm restart

    Re: Something is still wrong...

    I followed your directions and successfully restarted GDM. I am still getting the bluescreen. Something weird now is that the flickering and bluescreening occurs even in the 1st text terminal while I am using nano (or whatever else). Before it was just in the graphical terminal. When it didn't work I verified in Xorg.0.log that AIGLX was off, and that no new errors were appearing.

    Any other ideas?
    Thanks.

    Does this happen on a standard ubuntu disk too? If not, you can scp in your xorg.conf in to the live boot session. Also, if this is the case, you can really help the xorg developers corner a related bug by getting your non functional xorg.conf, Xorg.0.log* files, and the functional xorg.conf on a bug tracker.
