    Is downgrading to an earlier xorg that supports NV better than running noveau with the MSI interrupts disabled?

    I didnt know what midori was until this thread. It didnt work until after I installed the patched webkit. Works now. Cool.

    Probably not. I think it might be slower in 14.04, and I possibly missed off a patch in the xserver-xorg package so you might get rendering errors with nv. Dunno really, I don't have a nvidia card.

    EDIT: patch already there https://bugs.launchpad.net/ubuntu/+s...u/+bug/1010794

    There's a newer version of Midori now which I missed. I can share that if people want it, but I've been experimenting with building it with webkit2. For those that don't know, webkit1 isn't really getting security updates anymore and everything is going to have to switch to webkit2. The next release of Midori will probably be webkit2 only.

    The problem is, webkit2 seems to be severely broken on powerpc. Has anybody got it working in any version of *buntu/debian/etc? Epiphany-browser uses webkit2, and that's the best thing to try. This forum works on it, but BBC news and YouTube just show a mess - a bizarre page of Chinese characters, a blank page, or just a mess of graphics corruption. Thoughts?

    Yeah, but did it work on all sites e.g. YouTube?

    Hi,
    I tried upgrading 12.04 to 14.04 on my PowerBook G4, and using your NVidia driver packages, but I didn't get it working. Do you have changes to sources somewhere like GitHub?

    I did not take backups before upgrading, so I needed to figure out how to get 12.04 working again with nv driver.

    First I downloaded Ubuntu PowerPC alternative install, installed in text mode, setup static IP because my DHCP didn't work. I did setup partitions as they were from previous install, dual boot with Mac OS X.

    Then I started in boot menu l = linux, and then "Linux single nomodeset" to get to console.

    I installed all updates.

    To get ssh access for doing copy-paste commands easier, I did install ssh and start it (it's not started automatically on single user mode):

    Code:
    sudo apt-get install ssh
    sudo service ssh start
    Compile instructions for nv module are here:
    http://ubuntuforums.org/showthread.p...0#post12922410

    I think source is originally from here:
    http://cgit.freedesktop.org/xorg/driver/xf86-video-nv/

    Anyway, I have previously downloaded source files as working backup here, with compiled deb package:
    https://sites.google.com/site/lauriojansivu/nv.zip

    And here is just the compiled deb package, that works as of today:
    https://sites.google.com/site/laurio...-3_powerpc.deb

    After installing deb package, add xorg settings to /etc/X11/xorg.conf, I got this info from here:
    http://ubuntuforums.org/showthread.php?t=2131644

    Code:
    sudo nano /etc/X11/xorg.conf
    There add this text:

    Code:
    Section "Device"
    Identifier "Configured Video Device"
    Driver "nv"
    EndSection
    
    Section "Monitor"
    Identifier "Configured Monitor"
    EndSection
    
    Section "Screen"
    Identifier "Screen0"
    Device "nVidia"
    Monitor "Monitor"
    DefaultDepth 16
    SubSection "Display"
    Viewport 0 0
    Depth 16
    Modes "1024x768"
    EndSubSection
    EndSection
    Then blacklist nouveau driver:

    Code:
    sudo nano /etc/modprobe.d/blacklist-framebuffer.conf
    And add there at beginning of list add:

    Code:
    blacklist nouveau
    And save.
    To install WLAN drivers:

    Code:
    sudo apt-get install firmware-b43legacy-installer
    Then reboot:

    Code:
    sudo reboot
    And boot with l = Linux, and Enter (no boot options)

    BTW, if you get black screen when booting in graphical mode, it means that login screen may be visible, so just write your: username TAB password ENTER to continue booting. But anyway, this is not necessary when NV driver is installed correctly.

    Next time I will backup before trying newer Ubuntu version.

    That's a shame. Thanks for trying.

    Did you get any logs off the failed 14.04 install?

    If you want to give it another go without reinstalling everything (and you have the hard drive space), then use the wubi instructions https://wiki.ubuntu.com/PowerPCFAQ#C..._.27wubi.27.3F

    I should add about the wubi instructions, you could skip the creating of the root and swap disks. You could test it all from just the installation ISO. Boot into text mode/single user with nomodeset,

    cd /isodevice/home/insert-your-username/Downloads/etc

    install the debs etc and start lightdm

    I'm sure upgrading from 12.04 to 14.04 could of caused you problems, particularly if you are using Ubuntu and not lubuntu. The upgrade paths have not been tested well.

    Re: Radeon UMS, mach64, r128, nv in 14.04

    Hi,
    yes I'm very interested in trying again. It was originally Lubuntu 12.04 install where I installed Ubuntu desktop, and tried graphical upgrade. After upgrade screen flashed, it could not startx properly after 14.04 text. I did not save any logs. Ubuntu 12.04 only has Firefox 39, and I'd like to compile software that requires libs from 14.04. I will try again later this week, or weekend. What logs would be most useful? Do I need to install all packages, or only xorg core, nv, webkit etc?
