"xset dpms force standby" not working (Slitaz 3.0)

Hi All,

I love the package after having played with DSL and GRML. Hats off to the group.

I've booted off the LiveCD and found that the screen never blanks or jo into screen saving mode. I installed the "xset" package "xorg-xset-1.0.4.tazpkg" to try to understand this and this is what I found/did:

The command was invoked as follows:

         sleep 3; xset dpms force standby

The other related commands also do not work:

         sleep 3; xset dpms force standby

         sleep 3; xset dpms force standby

I also try an experiment to redefine the intervals and to poll the state of DPMS using "xset -q" in a seperate window, as follows:

Window 1 xterm:

xset dpms 10 11 12

Window 2 xterm script (for monitoring):

while true

do

   echo ""

   sleep 2

   xset -q

done

The above scripts shows that "xset" does indeed go through the various standby, suspend and off states at roughly 10 seconds(standby), 20 seconds(suspend) and 30 second points(off) BUT the monitor STAYS ON with a stable image   I'm not sure if this is a hardware/motherboard issue with my Asus P5G41T-M motherboard (G41 integrate graphics aka x4500).

Here is the the listing for "lspci":

00:00.0 Host bridge: Intel Corporation 4 Series Chipset DRAM Controller (rev 03)

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

Vesa driver on stable (2.6.30.6-slitaz) DPMS+intel graphics broken.

If you install xorg-xf86-video-intel and it's depends DPMS works.

Use tazx which requires an internet connection.

Vesa driver on cooking (2.6.37-slitaz) DPMS+intel graphics works.

Re: "xset dpms force standby" not working (Slitaz 3.0)

Thanks 'mojo' for the info. Today I looked at my other system running Ubuntu 8.10

and took a look at the the differences in the dependency list for "xset" via "ldd xset":

For Slitaz using Vesa:

tux@slitaz:~# ldd --list /usr/bin/xset

        linux-gate.so.1 =>  (0xffffe000)

        libXmuu.so.1 => /usr/lib/libXmuu.so.1 (0xb8030000)

        libX11.so.6 => /usr/lib/libX11.so.6 (0xb7ef2000)

        libXext.so.6 => /usr/lib/libXext.so.6 (0xb7ee1000)

        libXp.so.6 => /usr/lib/libXp.so.6 (0xb7ed8000)

        libXau.so.6 => /usr/lib/libXau.so.6 (0xb7ed4000)

        libc.so.6 => /lib/libc.so.6 (0xb7d6e000)

        libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb7d68000)

        libdl.so.2 => /lib/libdl.so.2 (0xb7d64000)

        /lib/ld-linux.so.2 => /lib/ld-2.10.1.so (0xb8035000)

and for the Ubuntu system (2.6.27-7):

peak@PeAK:/$ ldd /usr/bin/xset

    linux-gate.so.1 =>  (0xb7f79000)

    libXmuu.so.1 => /usr/lib/libXmuu.so.1 (0xb7f3f000)

    libXext.so.6 => /usr/lib/libXext.so.6 (0xb7f30000)

    libX11.so.6 => /usr/lib/libX11.so.6 (0xb7e40000)

            libXxf86misc.so.1 => /usr/lib/libXxf86misc.so.1 (0xb7e3d000)

    libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7cdf000)

    libXau.so.6 => /usr/lib/libXau.so.6 (0xb7cdc000)

            libxcb-xlib.so.0 => /usr/lib/libxcb-xlib.so.0 (0xb7cd9000)

    libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb7cc0000)

    libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7cbb000)

    /lib/ld-linux.so.2 (0xb7f5f000)

    libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb7cb6000)

I've indented the libs/lines that are different and they are in libraries

libXxf86misc.so.1 and libxcb-xlib.so.0

Hopefully this helps sort out the brokenish...

The vesa 2.3.0 driver fix's intel graphics DPMS and improves X autoconfiguration:

Re: "xset dpms force standby" not working (Slitaz 3.0)

I've just rolled the changes by remastering the rootfs.gz file (via writeiso) and

now have blanking working off the boot.  I thought backported 2-3.0 vesa fix would

get backported into the STABLE 3.0 release but when I recharged the package list, yesterday, it had

not changed and still contained the Vesa 2-0 module with the broken DPMS.

Mojo, I understand the concept of taking a snapshot but how do you reconcile

someone bumping up against the same dpms  problems with an older release short of using the

the "newish" cooking release ?

Using the JWM/Windows analogy, why not have an upgraded recharge list called 3.1 containing

only the updated packages that have been fixed...sort of like a "service pack?

Some might call it legacy support.
