There weren't any obvious message on the screen. X isn't working

I wanted to get back to this problem tonight so I'm just taking a

My archives go back a year or so.  The only problem I could find was 
when I had trouble with KDE compiling.  It wasn't cmake itself that was 
failing tho, it was kdelibs.


I also checked my emerge.log and I have updated emerge with no failures 
so far.  You may have to post the error and see if someone can help.  
Maybe a missing/bad USE flag or something.

  The command for that *IN X WINDOWS* is...

xset dpms force off

  If you want to do it manually from the keyboard, I suggest typing...

sleep 3 ; xset dpms force off

  This will wait 3 seconds before switching the screen off.  Any mouse
or keyboard action should wake up the screen.  The 3 second delay is so
that the keyboard bouncing back from you hitting {ENTER} doesn't wake up
the screen.

Hi Walter,

thanks a lot for your reply :)

I tried chvt 1 by hand and it generates the same "color flash" as
the automatic switch to the console while shutting down my box.

I think, switching to the console as such isnt the problem here as it works.
The problem is the switching process itsself. "To switch" generates
that flickering colors. 
May be turning off brightness, switching and turning on brightness

  The command you want is "chvt".  E.g...

chvt 1

...will change you over to text console 1, just like the {CTRL-ALT-F1}
key combo.  You may want to try "chvt 12" (equivalant to {CTRL-ALT-F12}

[gentoo-user] Beautifying goot and halt process

[meino . cramer]

Hi,

with my Linux I use a HP LW2475w lfatscreen monitor. 
When I halt the computer there is a point in the shutdown
process when Linux shutoff X11 and switch to console. 
When this happens, a not-so-nice "colored flash" 
is seen most of the thime at the lower part of
the screen. This looks like that there is something
wrong, technically incorrect (I know it is not) and
its look inperfect and odd.

Is there any way to switch a flatscreen to console
without this "color explosions" ?

Thanks a lot in advance for any help!

[gentoo-user] cmake-2.8.1 build problems

[Mark Knecht]

Hi,
   I was trying to slog through all the libpng problems on one of my
machines last night but ran into a different issue late in the evening
where cmake wouldn't build. I haven't been reading this list all that
carefully and didn't find anything obvious with a quick Google search.
(Other than some stuff in bugzilla which may or may not relate.)

   Have there been any threads lately where this might have come up?

   There weren't any obvious message on the screen. X isn't working
due to gdm not starting because of libpng and I didn't have a spare
machine to ssh from at the time to really study the build log files.

   I wanted to get back to this problem tonight so I'm just taking a
quick reading on whether there might be some related info out there.

Thanks,
Mark

Oh - I wasn't aware of that key - nice :)

With htop I do see 4 mplayer processes with both mplayer and
mplayer-uau... (can't sort properly with top) but only 1 process really
uses any cpu time... I wonder if mplayer-uau is really using ffmpeg-mt
(I did set the use flag)...

Thanks for the thought.  I had tried it before, but seeing how you
specified it, I think I had done it wrong (1600x900-59; I was leaving
the computer to try and figure out the colour depth it liked).  I tried
it your way as well (1600x900...@59), but that didn't work either.  And
just to be thorough, I tried 1600x...@59, but still no go.  :-(

Does anyone know if mplayer-uau uses "-lavdopts threads=2" by default?
 I tried with and without and there might have been a performance
increase with, but I'm not sure.

I gave that a try and it smoothed everything right out, so I guess it
was a CPU issue after all.  Thank you for your help.  How is
mplayer-uau different from mplayer-mt?  Maybe mplayer-mt can't be
installed alongside mplayer?

No change with "-ao null".  I actually don't use pulseaudio.

I'm trying to move away from VDPAU.  It fixes the performance issue

[gentoo-user] current network traffic rate, in real time (in console)?

[Jarry]

Hi,

I would like to see in console current network transfer rate
for given interface, similar as I can see cpu-loading in [%]
with "top" command.

Just single overall value in [bytes/second] or similar unit
would be enough for me, averaged over certain short time
interval (let's say 1 or 5 seconds). How could I do that?

Re: [gentoo-user] libvirt needs VirtualBox XPCOMC

[App Deb]

Do you want to use libvirt with virtualbox? If not (say you want to use it
with kvm or something else) try emerging libvirt without the virtualbox flag
using package.use .

Else try emerging virtualbox-ose or virtualbox-bin befire libvirt.

But this is probably a bug? libvirt should have virtualbox as a dependency
if the use flag is enabled, I think.

Re: [gentoo-user] (gnome) default pdf viewer

[App Deb]

This is installed from wine applications, and yes unfortunately they can
create a mess (like making the wine "notepad" the default text editor).

You need to delete those mime applications that wine creates under your home
folder.

Try something like:
rm -rf $HOME/.local/share/applications/wine

or search and delete the file that you told me (wine-extension-pdf).

The previous gnome instructions I told you should have worked though.

Re: [gentoo-user] installing app-emulation/wine-1.1.44

[Rod Hurford]

Petri,
a nudge in the right direction, many thanks.

My thoughts had drifted towards the emul-linux-x86-* libraries being
out of date and some of the discussion comments in the bug report you
linked confirmed that it was most likely them. (I hadn't considerd
them until now because I had thought I had kept my system up to date,
but obviously I hadn't :( )

I have manually updated the emul-linux-x86-* libraries and upgraded to
wine-1.1.44 without a problem.

Thanks for your help,
Rod

Unfortunately, not for me (Gnome 2.30)
Before and after the above procedure I have

gnomevfs-info MyFile.pdf
still shows
MIME type : application/pdf
Default app   : wine-extension-pdf.desktop

I wonder where this 'wine-extension-pdf.desktop' is coming from.

And Balsa tries to use this when viewing a pdf attachment.

This may be a bit of a long shot, but: according to the modes file you
included, your monitor only actually supports 1600x900 at 59 Hz.  Since
you aren't specifying a refresh, uvesafb says in dmesg that it is using
a default refresh.  My guess is that means "60", rather than some smart
value.  Does anything different happen if you specify the full mode,
e.g. 1600x900...@59?

I'm afraid if that doesn't help I'm not likely to be much good myself. 
But I thought seeing that 59 there was odd, and figure it might be worth
a look.

Oh - didn't think about this - yes... you could be seeing the wrong
thing in "top". If you have more than 1 CPU/Core you should push "1" in
"top" to get separate statistics per CPU/Core. Push "W" to save your
settings. (Use "s" to change statistics collection time, "1" sec. is good.)

Use "htop" to see threads. As far as I know "top" won't show those. So
you can't check if your multi-threaded mplayer is really using more than
1 thread/process.

BTW: On my core2duo 2,4 GHz I have no problems watching H.264 encoded
1080p videos with AAC sound. All decoding is done in software. When I
use original mplayer 720p is possible without problem, 1080p only with
low bitrate. For high bitrate 1080p I need the mt-version.

Re: [gentoo-user] (gnome) default pdf viewer

[App Deb]

Right click on a pdf file, select properties -> open with -> and select
evince instead of acroread.

That it the way to easily change default applications for gnome.

Re: [gentoo-user] Why does high-res video drop frames at 60% CPU?

[App Deb]

You have dual core so 60% means:

50% (full one core) is for decoding,

and the rest 10% is for audio, resizing etc.

You can't play the video correctly because your "decoder" is not
multithreaded and uses just the one CPU at its fullest.

Try using multithreaded version of mplayer "mplayer-mt" (in some overlay
probably) with "lavdopts=threads=2" in mplayer config.

Regarding mplayer: There is another ebuild in the multimedia-overlay
that I prefer now to mplayer(-mt) and that also uses ffmpeg-mt :
media-video/mplayer-uau.

It fetches the mplayer-version from one of the mplayer-devs and creates
a binary called "mplayer-uau" which can be installed at the same time as
the official mplayer package.

Regarding your frame drops: it is highly likely that sound is the
problem. Please try playing the video with "-ao null" to see if that's
the case. I assume you use pulseaudio? Check if it has real time
capabilities (kill it, start it with verbose/debug in foreground, read
log). Also try "-ao alsa" and "-ao oss".

Your data-source (gard disk, network?) is fast enough? Copy 1GB into RAM
to be sure by ether using RAM-disk or cache-settings.

Try nvidia-binary. You'll get VDPAU in that case, which will result in
about 5% CPU usage when decoding h264!

Hope some of this helps...
Daniel
