Problems with extended desktop on ubuntu hardy

This is a work in progress doc
https://help.ubuntu.com/community/XORGHardy

it will explain the situation with the xorg config.

Detecting the monitor real time is / has been an issue in the past, and can be twitchy depending on the driver your using.

Not a fix I'm afraid just information to help.

Hi Agustin,

   I also have ubuntu hardy on a Toshiba Portege M400 laptop, and I have exactly the same two problems that you signal in your email. Did you find any fix during these months?

Thank you,
Maurizio

I wish I had..., actually, I've given up. I even could not
use my laptop for a presentation.

Please let me know of any progress you could make.

Agus

Found a solution! (With the help of a local guru)

The problem is solved with the toshset command.
The following two commands mirror the LVDS to the VGA on my Toshiba Portege M400 laptop with ubuntu hardy:

   root@tittolo:~# toshset64 -video both
   root@tittolo:~# xrandr --output VGA --mode 1280x1024

A second problem is that the toshset command is contained into the toshset_1.72-6ubuntu1_i386.deb package which is not available as a 64 bit binary. This second problem can be in turn solved by downloading this file:
http://www.schwieters.org/toshset/toshset64.gz
from this page:
http://www.schwieters.org/toshset/

Hence, to summarize:
1) download http://www.schwieters.org/toshset/toshset64.gz
2) execute "gunzip toshset64.gz"
3) execute "chmod +x toshset64"
4) connect the external video
5) execute "sudo ./toshset64 -video both"
6) execute "sudo xrandr --output VGA --mode 1280x1024" (or whatever geometry works for your external monitor)

Ciao,
Maurizio

Thanks, just one doubt before I actually do it,
why do we need the 64bit version?

...and can you get an extended desktop or just
a cloned display?

Thanks!

The 32 bit toshset binary seems not work on my Toshiba Portege M400: I forced the installation of toshset_1.72-6ubuntu1_i386.deb and tried to launch "toshset". Each time I obtained a "wrong architecture" error message. Hence I purged it.

From this output:

patrigna@tittolo:~$ uname -a
Linux tittolo 2.6.24-19-rt #1 SMP PREEMPT RT Wed Aug 20 20:13:12 UTC 2008 x86_64 GNU/Linux
patrigna@tittolo:~$

it seems that I have a 64 bit architecture.
If you have a 32 bits platform then the package toshset_1.72-6ubuntu1_i386.deb will suffice.

With the recipe above you get a cloned display only. I didn't try other configurations. I need to make some presentations.

Ciao,
Maurizio

Maurizio:

1. I can successfully run the standard toshset binary that
can be installed with Synaptic: the laptop display
gets an standard brightness

2. I'm intrigued by the 64 bit issue, we are supposed to have
the same machine. Did you install a 64bit
ubuntu distribution? If you could, please install and run sysinfo. My
processor is Intel Core 2 T7200.

3. I've been able to set up an extended desktop using
the standard tool under System/Preferences/Screen Resolution

4. Just have to run
sudo toshset -video both

each time I restart the computer with the external
monitor

Good luck and thanks

Agus

Dear Agus,

  thank you for your feedback.

> Did you install a 64bit ubuntu distribution?

Apparently yes. I was not aware of it at the time ;-)

> If you could, please install and run sysinfo. My processor is Intel Core 2 T7200.

Done. This is also my processor. I think it is 64 bits, otherwise I don't understand how I could install a 64bit ubuntu distribution.

Ciao,
Maurizio
