Mandriva 2009 (fresh install) on a Shuttle SS51G.

The problem seems to be somewhere in KDE 4. I've tried Gnome and it doesn't exhibit this problem though Gnome apps have no window decorations, so the X11 server *may* be exonerated. I've also tried a number of different video drivers including the generic vesa driver, as well as different resolutions. I've turned off options and 3D destop effects are disabled.

The problem is that whenever there is an update to the display (mouse movement, open a menu with the keyboard, etc.) the display resets, that is, it goes blank for a couple of seconds, then comes back with whatever changes would be expected (mouse pointer moved, menu open, whatever).

Some details. See below for a link to complete log and config files:

I really hope somebody has some suggestions on this.

Thanks.

Anybody?

Code: Select all

(II) "dri" will be loaded even though the default is to disable it.

Also could you try without GLX, it seems to want DRI, which you disabled.

Have you tried without KWin running ( ie. No window manager in KDE4 ) or with a window manager running in Gnome?

I haven't figured out how to disable glx or dri. I have this in my xorg.conf file:

Code: Select all

Section "Module"
    Disable "dri"
    Load "dbe" # Double-Buffering Extension
    Load "v4l" # Video for Linux
    Load "extmod"
    Load "type1"
    Load "freetype"
    Disable "glx"
    #    Load "glx" # 3D layer
EndSection

And further down:

Section "Device"
    Identifier "device1"
    BoardName "SiS SiS 670 / 671-based cards"
    Driver "sisimedia"
    Option "DPMS"
    Option "DRI" "no"
    Option "glx" "no"
EndSection

But I keep seeing this in the Xorg.0.log file. Note the "<<---?":

Code: Select all

(WW) "dri" will not be loaded unless you've specified it to be loaded elsewhere.
(WW) "glx" will not be loaded unless you've specified it to be loaded elsewhere.
(II) "extmod" will be loaded. This was enabled by default and also specified in the config file.
(II) "dbe" will be loaded. This was enabled by default and also specified in the config file.
(II) "glx" will be loaded even though the default is to disable it. <<---?
(II) "freetype" will be loaded. This was enabled by default and also specified in the config file.
(II) "type1" will be loaded. This was enabled by default and also specified in the config file.
(II) "record" will be loaded by default.
(II) "dri" will be loaded even though the default is to disable it.<<---?

As for Kwin, killing kwin in a kde session causes my window decorations to instantly disappear. Starting kwin in a Gnome session causes it to complain about a Dcop connection (or something), and blow out my wallpaper, but it does give me window decorations.

I don't know.

Did having kwin not running cause the screen resets to go away?

Also "freetype" replaced "type1" so "type1" is deprecated.
Also which version of Xorg do you have?

Unfortunately i am not an Xorg expert. If these fail you may need to try your distribution's forum. I believe KDE4 is triggering a bug somewhere in Xorg as it is the only thing that could reset your screen. It is pushing the boundries after all, which is what causes the Nvidia problems.

Ah, I guess I could have mentioned that since it is the reason this post exists.

Gnome has never had the reset problem. KDE continues to experience the reset problem when kwin is killed.

Also "freetype" replaced "type1" so "type1" is deprecated.
Also which version of Xorg do you have?

Here's the installation package for 2009: xorg-x11-7.3-4mdv2009.0.i586

I assume that means I'm running ver. 7.3.

Been there, done that. So far, no joy.

Thanks Cooksley. I'll try to pass that along.
