From the hplip ebuild:

elog "You should run hp-setup as root if you are installing hplip for
the first time,"
elog "and may also need to run it if you are upgrading from an earlier
version."


This message is there for a reason!

Start by resetting to all defaults.. ;-) Many motherboards these days
support "unsafe" settings (overclocking, etc.) and warn you that you
can destabilize your board. If you, or anyone else, has ever tweaked
those it may be unstable. So try all defaults, or "safe settings" first
if you haven't already.

Except the problem with the binpkg was most significant on the system

well, it is not like you have much alternatives left, do you? you can either:
try a different keyboard
try a different adaptor
or
connect the keyboard directly.

any way. changing 'usb legacy support' from 'disabled' or 'auto' to 'enabled'

Use the GIMP, Luke. I have to do this all the time with forms and
such. The GIMP imports PDF files nicely, and I usually print the file
to PDF after I am done. Now, if you have a many page document, the
GIMP will import each page as a layer which can make it a pain to have
to manually print each layer as a separate pdf, but ya do what ya
gotta do. I also like PDFShuffler for managing/mangling pdf files. Its
in portage by the way.

Are you the creator of the document and want to save the original as
greyscale, or you want to convert an already existing PDF?

If the latter I think the easy way is to use ghostscript (pdf2ps) to
render it as greyscale postscript. Then you could convert the PS back
to PDF if you need to. But if you already tried that, then, I don't
know...

I have threads set globally in make.conf and haven't run into any
issues. nptl and nptlonly are set via make.defaults in amd64 profile.

It doesn't seem like too many of the packages I actually use have a
"threads" use flag:

I'm sure many other packages use threads, but it isn't optional.

I think he wants the same PDF as the original file. Only in grayscale.

This is one method to do this, but it needs Acrobat 8 Professional:

Hi Volker,

The bootselector normally is used to select between different bootable
devices which are together connected to the PC at the same time.
Very handy!

One question remains to be answered for you: 
What could happen, when attaching a badly confirming device to a motherboard?

In the simplest case: nothing and it does not work.

Worst case is to kill the PS/2-chip attached to the PS/2 jack on the
motherboard.

Something with which I do not want to experiment with. 
Especially because I know from others, that this risk is real.

Normally I try to evaluate the risk of my acting in beforehand -- 
especially if it is that easy like in this case: asking people, 
which wants to give helpful answers. But not any given answer is 
that helpful, you know?

Have a nice weekend!

USE=nptl means build the  New Posix Thread Library.
USE=nptlonly means only built NPTL, not the old Linux Threads

These should be global in scope

USE=threads is best per package as some packages support it but don't play 
nice with it. You could set it globally and disable it per-package, or do it 
the other way round if you please.

AFAIR nptlonly has done nothing for ages. When was LinuxThreads removed from 
glibc? Sometime around 2.6 or 2.7?

Hi Volker,

...yes, there is a ps/2 port...but this keyboard is that old, that it is
recommended NOT to connect the keyboard to ANY "modern" PS/2
connector, since it does not comply to the standard very well.
I choose exactly this adapter, because it is known to work with the
keyboards "way of PS/2". If there is a little chance to enter BIOS and
the BOOTSELECTOR using this keyboard I want really to avoid the hassle 
of having two boards connected to my PC (and wasting a USB port,
too).

[gentoo-user] Chromium requires threads flag

[James]

Hello,

I have nptl and nptlonly set in my make.conf file.
I thought that was the best setting for threading.


Now, I want to install the Chromium web browser.
It is asking me to the set the +threads flag for ffmpeg,
before www-client/chromium can be installed. OK
no problem on a per package basis.

But, this has made me think. Is setting nptl and
nptl globally (in make.conf) the best idea? 

Should the threads flag also be set globally, or just 
on a per package basis? Maybe nptl and threads
and not set nptlonly?

I thought nptl and nptl was the end of the
requirements, but running this command:

euse -i threads
Here is a curious response; ffmpeg does not get 
listed (as it is not built with the threads flag)?

euse -I threads

I see lots of packages where the flag "threads"
is being used including ffmpeg.


Some discussion and guidance as to how best
to set the flags [nptl, nptlonly and threads]
(any others related to threading) would be
appreciated.

go into bios, turn on legacy support. Btw, are there no ps/2 ports? Oh - and

At my job we have some Dell computers, where the USB keyboard doesn't
respond for more than 1 minute after the machine boots UNLESS it is
plugged into a specific USB port. So maybe you can try to use
different ports, just in case it's a similar problem.

[gentoo-user] PS/2->USB-Keyboard and the BIOS

[meino . cramer]

Hi,

I have a problem here...(as you may have already guessed...;)

I have an old PS/2 keyboard, which I do love a lot. This PS/2-
keyboard is connected via a Chesen Electronics Corp. PS/2 Keyboard+Mouse Adapter
to an USB-port of my ASUS Corsshair IV formula board.

When Linux is running I have not a single problem with this setup...
BUT entering the bootselector via F8 while BIOS is coming up is
to 99% impossible. I managed that only once.
On the other hand: Entering BIOS with F1 is not simple and often
requires several boots, but it is possible.

What can I do to make F8/the bootselector work?

Thank you very much for any help in advance!
Have a nice weekend!
Best regards,
mcc

wtf?

no, the 2.12.1 binpackage does not know which versions are installed. It just 
includes a version check.
If no glibc is installed (and removing the /var/db/pkg/sys-libs/glibc-2.13 
directory = no glibc installed) then you are free to install any binpkg you 
want.

Or, you know, just extract ld.so from a tarball, copy it into /lib, and un-
prelink your system. Then re-install 2.13. Problem solved.

That's what I thought. I have run memtest86+ overnight, but of course it 
didn't find anything.

As Gentoo seems to be immune to this problem, I assume that other kernels 
are setting some parameters that push the hardware to its limit, so the next 
thing I'll try is to detune the performance somewhat. Trouble is, the BIOS 
setup screens have so many parameters to adjust that I don't know where to 
start.

[gentoo-user] using meld with cfg-update -u

[Allan Gottlieb]

I have been using cfg-update quite happily for a good while.
I appreciate its automatically doing "simple" updates.

For any that it can't do automatically, I have done them manually
(using emacs/ediff).  I decided to try meld instead (I use gnome).

It does make everything clear, but something seems wrong.  Cfg-update
keeps a backup containing the previous version of the file.  When
cfg-update invokes meld, the three relevant versions are displayed
in meld's window like this

current backup  new (._*)

I believe I want the final state to be
  backup = current
and
  current = merger of current and new

But current and new are not adjacent on the meld so I don't see how to
do this using the fancy meld mouse actions.  It seems to me, I want meld
to display

backupcurrentnew

then, for each change that I want from new, I push new version to
current.
But I don't see how to have cfg-update call meld in this order and I
don't see how to have meld swap the two left panes.
(I am assuming that cfg-update will arrange that when I am finished
backup = current-before-meld.
If not, I can do this in meld)

Can someone tell me how to get the configuration I want or explain why
the configuration I get is actually what I (should) want.

thanks,
allan

I find that in virt-manager as well, it is set to localtime.
Next there is ACPI and APIC  both inactive? Should I change that??

Where to put that? Can I somehow set that with virt-manager or where to
edit that?

We have the "benchmark" that one app-logo should be shown for 2 secs
when opening the app.

If I access the VM by virt-manager alone, it is OK. And the clock does
not drift.

As soon as the other guy connects via RDP or netviewer it gets bad.

The logo stays there for about 10 sec or so ... and the clock gets slooower.

Hi,

I use kvm on gentoo, I really don't use the clock on the windows
guests (I don't use windows vm) :). But I could guess that the issue
might be with localtime, so you could try using  "-rtc base=localtime"
parameter with starting the windows host.

Another fact:

When I access the guest via RDP, it is slower than when I access it via
the libvirt-console (which in fact is VNC, right?)

[gentoo-user] Qemu-KVM on amd64: clock in Windows guest

[Stefan G. Weichinger]

Greets,

does anyone else run KVM on gentoo as well?

I delivered a amd64-server these days and a Win7-pro-guest runs on it.

Now they tell me they have clock issues in the guest :-(

I found

http://docs.fedoraproject.org/en-US/Fedora/13/html/Virtualization_Guide/chap-Virtualization-KVM_guest_timing_management.html

and ran "bcdedit /set {default} USEPLATFORMCLOCK on", didn't help, even
after reboot. Does it really have to say "{default}" ??

I don't know where to start.

The host kernel provides /dev/rtc, does currently have CPU_FREQ=y, but
afai understand I don't use that behavior (no driver or governor loaded).

Is CONFIG_HPET needed? ->

# grep -i hpet .config
CONFIG_HPET_TIMER=y
CONFIG_HPET_EMULATE_RTC=y
# CONFIG_HPET is not set

-

A kind of workaround is maybe using ntp in the guest?
I will try that asap.

Thanks for any help on this!

Stefan
