    Nouveau issues after upgrade - able to login but nothing else

    I upgraded my desktop (which is reasonably old) to 19.04, which went fine. When it booted up again I was able to get to the login screen, select my user, type my password and login. I saw the desktop with the dock down the side. the Mouse moves on screen, but nothing else will work.

    the graphics card in the box is NVIDIA Corporation G94 [GeForce 9600 GT] (rev a1)

    I can ssh ok to the desktop from my laptop. When I first checked dmesg I saw 3 errors similar to:

    nouveau 0000:02:00.0: vp: unable to load firmware nouveau/nv84_xuc00f

    Note that these errors don't appear on boot up – i.e. when the login is displayed. They're only logged after logging in.

    Google didn't give me much, however I found some discussion about firmware missing here:

    https://nouveau.freedesktop.org/wiki/VideoAcceleration/

    I then followed the instructions under the section with header:

    "If your distribution isn't in the list, you can run the following commands to install the firmware:"

    The errors listed via dmesg then disappeared, however the symptoms are still the same. Clicking on icons, typing keyboard etc. does nothing, after initial login.

    Any tips?

    Have you tried puting nomodeset in the grub boot line?

    Re: Nouveau issues after upgrade - able to login but nothing else

    Were you using the proprietary Nvidia drivers prior to the upgrade?
    If so make sure they were removed. That has caused me problems with some recent upgrades.
    Also the desktop and desktop manager may be causing problems. I've had that happen as well.

    If that doesn't work please post information on you video drivers,

    I tried nomodeset but it didn't change anything.

    I thought I was running the nvidia driver before update, but checking for it now I can't find any nvidia packages installed.

    When you say "post information on your video drivers" what specifically do you suggest?

    lshw -c video shows the following

    The
    ubuntu-drivers
    command line utility will help install the recommended driver for your Nvidia card. Yes, you could also use apt to install something very specific, but it seems like you just need to get your Nvidia environment running first.

    Re: Nouveau issues after upgrade - able to login but nothing else

    So this is still a little weird, and I'm not sure it's related to video now... or not entirely. the following is now displayed in dmesg:

    [ 21.326352] WARNING: kernel stack frame pointer at 00000000d4fbb38d in Xorg:2363 has bad value 000000008700762a
    [ 21.326354] unwind stack type:0 next_sp: (null) mask:0x2 graph_idx:0

    followed by stacks of lines with hex values.

    However the display is all appearing fine and if (eg.) I plug in an external device the device notification is displayed. The time is updating, other notifications update regularly. I can move the mouse, but no click appears to register. Also keyboard doesn't appear to be working within x - I can Ctrl-Alt-F<x> and get to a terminal. sometimes a key press will register, although it may take a long time - i.e. I hit the Win key a while ago, and the search box has just appeared. Remoting in and looking at cpu usage, there is nothing running too hard. I haven't found any other obvious errors.

    I'm going to boot of a live USB shortly and see what happens - if all's good, I may reinstall, however would prefer not to have to...
