[ltp] thinkpad x40, ubuntu, and the latest xorg update.

[Jaime Davila]

Hello all,

Hello all,

I am running ubuntu 7.10 on a levono x40 laptop, with the 82852/855GM 
Integrated Graphics Device. Several days ago, after returning to the 
office with it, I notice that the external monitor is not coming on. 
That is, I get exactly what I would expect on the laptop's screen, but 
nothing on the external monitor. I have tried both having the monitor 
connected to the laptop's docking station, and connecting the screen 
directly to the laptop when the laptop is outside the docking station. 
The screen is OK, though, since it works on a different computer. I have 
booted the laptop up both inside and outside the docking station.

When I press fn-f7 to switch the display, I do get a confirmation that 
the acpi event was detected in /var/log/acpid. But the script configured 
in /etc/acpi/events to run on that event is /bin/true, as configured in 
/etc/acpi/events/ibm-videobtn. That file has a time stamp of May 23 
2006, well before the xorg upgrade, of course. My xorg.cong has a time 
stamp of November 1, 2007. But, I do recall that there were some 
upgrades to the xorg system that I installed after having them announced 
by ubuntu's update manager a few days ago.

As further confirmation of xorg being involved, fn-f7 in fact does its 
job if I press it while the system is booting up, up until the moment 
right before X starts.

I've done some searching on both the ubuntu forums and the web, but 
nothing useful has come up.

Any ideas?

Thanks in advance,

Jaime
