Thread: TW unusable on machine with nVidia graphics

  1. #1

    Default TW unusable on machine with nVidia graphics

    Display on logging onto KDE looks OK to begin with but on trying to do
    something like switching desktops, the display starts breaking up and
    freezing. Within a couple of minutes, it's impossible to do anything
    and the only way out is to hit the reset button.

    This problem began to develop a few weeks ago and, at first, I thought
    it was connected with the workspace theme I'd switched to; switching
    back to Breeze seemed to cure it. However, that turned out to be a fluke
    and the problem appeared there too after a day or so.

    I thought the kernel might have something to do with it so updated my
    13.2 session to the latest one, only to find I was now using a later
    version than TW. After a couple of weeks TW caught up but although 13.2
    gave no trouble, TW was still a mess.

    I next tried a clean install of TW from the last iso (20150714) but
    that didn't help at all.

    As with 13.2, I'm using the nouveau driver.

    Anyone seen similar trouble with nVidia graphics cards?

    I'm using an NV84 (GeForce 8600GTS) with the nouveau driver on an up to date TW and don't have any graphics issues.

    Maybe try changing the rendering backend (System Settings - Display & Monitor - Compositor), also check that the openGL interface is set to GLX and not EGL, which seems buggy at the moment.

    Could also try progressively disabling desktop effects to see if it's one of those causing the issue.

    Might try that if only I could get into the system for long enough
    before it breaks! ;-)

    I think my next attack will be to try another clean install but this
    time setting up a brand new user to see if that makes any difference.
    Could be there's some iffy personal settings left over. The current
    installation has only the one user and, of course, I can't get into
    root via the default logon panel. :-(

    For me, nouveau works pretty well if I disable desktop effects. But with desktop effects on, it is a mess. This is with an older 6150LE card. I have not recently tried with Tumbleweed, though I have tried running another distro from live media with plasma 5, and it was a mess.

    I recently tested openmandriva with KDE4, and that seemed quite stable. When I checked the desktop effects settings, they had been set to use Xrender instead of OpenGL. I'm not sure if that is possible with plasma5.

    With opensuse KDE4 and nouveau, I would login to Icewm, and find the settings file where I could turn off desktop effects with a text editor. I haven't tried that with Tumbleweed.

    One trouble I see with Plasma5 is that desktop effects can only be
    turned off item by item in the GUI; there is no overall switch-off
    button as there is with KDE4 - or, at least, I couldn't see one.

    The graphics was working fine until about a month ago; no idea what's
    changed.

    OK, done that and found that the new user works fine whilst the old
    users, three of them, just collapse in a nasty heap. So, it looks like
    local settings are the problem but they were not changed from default.
    Having said that, the new user might have different defaults, being
    from a later installation.

    Next move is to remove/rename some config files as root for a
    troublesome user and see if that makes a difference. Be useful to know
    which ones to go for, though. Any suggestions?

    Will also be trying to reproduce this on a non-nVidia machine.

    Of course it may not be a plasma/compositing issue... but if it is then:

    For starters I'd clear the users cache ( located ~/.cache and delete anything plasma* ) of the "plasma stuff" just to see if that makes any difference.

    The config files for plasma are plasma* located ~/.config I'd rename those.

    After that... your guess is as good as, if not better, than mine

    What happens if you disable compositing completely (alt-shift-F12)...

    I tried renaming .config/plasmashellrc first and that seems [fingers
    crossed here] to have done the trick. Configuration settings are
    different to the old one. Looks as though a change in KDE is yet again
    not compatible with old settings. That would explain why the newly
    created user-session was not affected.

    Luckily, after creating another clean install from 20150722, my user
    session stayed functional for long enough for me to change the login
    panel to one that would enable me to logon as root, thus giving me a
    chance to tinker with my user settings at leisure.

    OK, I give up. Worked for a few hours and then picture started breaking
    up and freezing until it reached the stage when the reset button came
    into its own again. Tried renaming all the plasma... config files but to
    no avail.

    Arg - I just installed Tumbleweed and am having the same issue - lots of tearing and refresh issues after the session has been open for a while. A reboot temporarily fixes the issue.

    My card is a GT 620.

    Have you tried installing the NVIDIA driver to see if it helps?
