[ydl-gen] xrandr and multiple screens

This may be of some interest to those struggling with second screens.
I recently modified my xorg.conf following information given in
<http://www.thinkwiki.org/wiki/Xorg_RandR_1.2>.  The basic proposition
is that xorg.conf kludges should not be needed to get clone or dual
monitor setups.  I based my xorg.conf on one generated from
Xautoconfig with some of the modifications suggested in the above
document (mainly the visual line).  With this done I could plug in an
external monitor to my iBook and get a display doing (for example):

xrandr --output LVDS --auto --output VGA-0 --auto --same-as LVDS

or

xrandr --output LVDS --auto --output VGA-0 --auto --below LVDS

For all fonts to diplay correctly the generated xorg.conf assumes all
font directories are found by the X Font server.  I ensured that all font
directories were added to /etc/fs/config using:

            chkfontpath --add directoryname

After this I ran (i) mkfontdir on each directory and then ran (ii)
'fc-cache -fv'.

[ydl-gen] Powerbook G4 '12 1.33 GHz shutdown issue

Hello everyone,

I just installed Yellow Dog 6.2 on my Powerbook G4 '12, 133 GHz.  Seems to be working great, exept one issue.

I've updated all the packages to the latest and it still shuts down when it's on idle which happens after about 30 minutes of being idle.  this doesn't appear to be from excessive cpu usage.  I've observed the cpu via system monitor and that seems to be working fine.

I'm suspecting it's a power configuration issue.  I didn't have this problem when I had Panther installed.

Does anyone have any ideas?  Let me know if you need any more information.

Regards,
Julian

This could be due to the settings for pbbuttonsd.  There are two power
related utilities that I recall: pbbuttons and pmud.  To check the
former try the command 'powerprefs' from the command line (or
equivalent to invoke 'PowerPrefs' from a gui).  Look for the settings
under both AC and battery.  There is a setting for the number of
seconds until suspend occurs.  

You can change this to a more appropriate value or set to 0 (no
suspend).

If you choose the latter then the machine will run till the battery is
close to running out (this is set by pmud).  The pmud setting is in
/etc/power/levels, I don't recall if there is a gui to set it.

If this is not the problem I don't have any other ideas at the moment.

[ydl-gen] Powerbook G4 '12, 1.33 GHz runs hot and shuts down

Hello everyone,

I'm afraid I didn't accurately describe my issue.

My install of Yellow Dog 6.2 went fine.

I left my mac on after using it for over an hour or so.  I like to leave my computer on because I know how turning it on and off is hard on a computer.  Anyways, when I wasn't using it, the fan seemed go full blast.  I glanced at the system monitor and the cpu seem to go to 100% without me doing anything on the computer (besides running system monitor of course.)  It then shutdown a few seconds after that.

Any help with this would be appreciated.

> Julian

This sounds like a scheduled task running.  I am not sure what the
system monitor reports (have not used it).  Does it report a task
running?  One way to check is, from a shell window, type 'top'.  This
command shows a list of active tasks and what percentage of cpu and
memory they consume (this is a standard unix command, also available
in OS/X).  Some system housekeeping tasks do use a fair amount of cpu
for a short while.

Once we know which task is running and using the cpu heavily we can
say more about it.  One old but useful description of unix scheduled
tasks is: 
<http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-autotasks.html>

I hope this is more helpful.

Re: [ydl-gen] Powerbook G4 '12, 1.33 GHz runs hot and shuts down

Hi Julian,

A couple of further comments.

A quick Google search did not find reports that seem to match exactly
what you are reporting.  As an alternative to the previous suggestion
(since it might not duplicate itself for some time) you may need to
look at the log files.  

After rebooting you will probably need to use sudo or su to root to
gain access, but from a shell go to /var/log, the most likely log files
to have information of relevance are messages, syslog and secure.
Look for the date and time at which the high cpu usage occurred.  See
what is listed and if anything looks like it was running at the time
or other information reported.  Since it is just before the shutdown
it should be relatively easy to find.

[ydl-gen] Printer for YDL 6.2 on a PS3

Hello everyone, is there anyone who can suggest me an inkjet color 
printer that is available now for which there is the YDL 6.2 driver ?  
Maybe HP or Epson USB printer.  I  bought an Epson Stylus S20 , but it's 
not compatible. I also had a look at CUPS, but the latest Epson driver 
is of August 2008.  Please help me !  Thanks in advance, Angelo

Hi Julian:

I did a little research on this problem and am sharing with you the link:
http://www.ehmac.ca/mac-ipod-help-troubleshooting/9004-powerbook-g4-fan-noise.html

If you read through the discussion you'll notice a section discussing the
wiring and the fan proper.  It just may be the case that you'll have to have
your powerbook checked out by Apple certified engineers to insure that more
serious problems don't exist.  I also found this link:

http://discussions.apple.com/thread.jspa?threadID=504823

However, essentially the solution is the same, take the powerbook to be
examined.

All the best...

[ydl-gen] Time Machine is the Devil

To all,

I share a ~300GB partition between YDL and OSX on both my 12" 
PowerBook and G5 Power mac workstation. For a few years now, this 
scheme has worked flawlessly, using rsync to migrate data (add, 
delete, mod) from one to the other, often more than once a day as I 
leave or return to my office.

The formatting of this shared partition is "OSX Extended, Case 
Sensitive", but without "Journaling" in order that the YDL kernel may 
read/write to this partition, as auto-mounted in /etc/fstab.

However, last week I was playing with Apple's Time Machine (and other 
backup software systems to determine which is most appropriate for my 
parents' home office. Little did I know that Time Machine modified my 
shared Data partition to "OSX Extended, Case Sensitive, Journaled" 
without so much as a warning block or query.

It took 2+ hrs to determine whey I could not auto-mount nor manually 
mount the /Data partition in read/write mode until a friend suggested 
I use Disk Utility to see if Journaling had been enabled. Sure 
enough, it had.

Unfortunately, just turning it off does not allow for Linux to again 
write to this partition, and so I had to reformat it using OSX with 
intent to copy over 200GB of data back to this partition.

Once again, OSX exhibited its independent will and modified my entire 
partition table, save the Apple and HFS boot partitions (sda1, sda2), 
meaning that I had to modify /etc/yaboot and run ybin in Rescue Mode 
from the YDL v6.2 DVD (thank you Owen and Chris for taking my half 
dozen exasperated calls today).

8 hours later, I am back up and running on my workstation.

It seems the "simpler" OSX is to use, the more is can really f&%! with 
your system, completely out of your control.

If I did not need to review movies for the Almost Famous Film Festival 
a few times a year and use iTunes to manage my iPod, I would very 
quickly remove it completely from my computers.

Ugh.

BTW, if anyone is interested in how to build a shared partition (which 
works very well, if you don't use Time Machine), feel free to contact 
me.

kai

Hi Angelo:

I recall that back in March (between March 10 - 12, 2010) a number of people
commented on this problem you reported.  I'm not sure that you read what was
posted back then but the general idea is that YDL as open source Linux relies
upon CUPS which collects drivers from HP, Epson and other companies which also
contribute open source version of the commercial drivers they make.

The commercial drivers prepared for Windows or the Mac OS have all the features
associated with a particular printer.  You can expect to have the printer's
scanner and other components to be fully supported within Windows or the Mac
OS.  However, it is best to be very clear and understand that under no
circumstances can you expect to have every feature supported within either x86
or ppc based Linux even though you are the same owner of the printer and that
printer is connected to the same computer.

It may be useful to keep in mind that the entire Linux market is so small that
companies find it more economical (and financially sensible) to support
Windows, and Macs.  This means that any consumer looking to have the full
functional capability of a printer available needs to be using almost
exclusively either Windows or the Mac.

CUPS, which is available for Linux, is very flexible and useful however there is
no way that the drivers available can have the features or capabilities of
drivers available for commercial operating systems.  Some open source drivers
are designed, on purpose, to allow a printer to have standard or basic printing
capability for a range of printer models sometimes across several
manufacturers. Commercial drivers are specialized for one model printer often
emphasizing the special components of that one model, maybe one or two within
one company.

Hopefully, this won't frustrate you.  You may indeed have a great printer, just
remember to use that printer within Windows if you want the full features of
that printer to be utilized.

As you are using a PS3, you could build or install (using yum) Wine or
other programs which allow you to run Windows from within YDL.  Using Wine (or
similar programs) you would have the full capabilities of the printer available
to you as the printer would believe that it was connected to a Windows
machine.  If this idea interests you, I recommend that you consult with and
become a member of the YDL Board community.  There are some really saavy and
skilled people there who could help you explore this idea and even guide you.

Implementing this idea isn't easy but it isn't impossible either.  As a project
it's an interesting means of exploiting the PS3's potential in a direction which
few take advantage of.

All the best...
