problems with video-intel driver

Sat Aug 11 00:08:16 PDT 2007

Hello,

I finally tested my i855GM with the git master version (I did it on 
8.8.2007). I only compiled the intel video driver, using the standard xorg (version7.2) and 
libdrm (version 2.3.0) shipped with Debian Lenny. The newdriver is considerably 
larger than the previous version, but the problem
(see below) still persist - after closing the lid the laptop freezes 
completely. I also put the newest Xorg.0.log on the web:
http://www-ucjf.troja.mff.cuni.cz/~davidek/xorg/Xorg.0.log.inteldriver_git
(but I don't see much difference with respect the version 2.1 - see also below)

On the top of it, I noticed another problem (probably present already with 
intel-2.1 driver). When suspending to RAM and recovering back, the Xwin system 
does not restore properly although the VBEtool is installed. The feature is 
that the Xorg system is "working", but most of X-applications inherrit black 
background from the screen, thus only the frames are visible. With the previous 
i810 driver, this was working well without any trouble.

Do you have any idea what's wrong or would you suggest another test to
be performed ? I know it sounds like a HW problem, but the previous i810
driver worked well.

Thanks a lot in advance for any hint,
           best regards
                                     Tomas

Hello,
I experienced a strange problem with the video-intel driver. The
version 2.0.0 did not work at all, but upgrading to 2.1 solved the
problem. However, when closing the lid, the screen gets blank with the
mouse cursor fixed in the last position and the laptop freezes
immediately without issuing any error message to any log file. Even the
ACPI even associated with the lid switch is not run.

When switching to text console (chvt 1) before closing the lid, the
system does not freeze and issues the hibernation to RAM as it should.
However, when resuming, the Xwin gets to a funny state - screen is
black, only the window frames are visible. Mouse still works, but
restarting Xwin does not help, I have to reboot.

Hardware: i855GM card on Dell Latitude D505

The Xorg versions I am running:
xserver-xorg 7.2
xserver-xorg-core 1.3.0
xserver-xorg-input-kbd 1.2.0
xserver-xorg-input-mouse 1.2.1
xserver-xorg-input-evdev 1.1.5
xserver-xorg-input-synaptics 0.14.7~git20070517
xserver-xorg-video-intel 2.1.0

I was running the 915resolution to hack VBIOS, but then I learnt it is
no more needed since video-intel 2.0 driver. That's really true, however
the above problem appears both with and without 915resolution hack.

When downgrading back to Debian/Etch versions, i.e:
xserver-xorg 7.1
xserver-xorg-core 1.1.1
xserver-xorg-input-kbd 1.1.0
xserver-xorg-input-mouse 1.1.1
xserver-xorg-input-evdev 1.1.2
xserver-xorg-input-synaptics 0.14.7
xserver-xorg-video-i810 1.7.2
(here I have to run 915resolution, otherwise I don't get my 1400x1050
screen's resolution working), both problems described above disappear.

I am running the kernel 2.6.21, the log files as well as Xorg config
file I made available on the Web:
http://www-ucjf.troja.mff.cuni.cz/~davidek/xorg/Xorg.0.log.inteldriver
http://www-ucjf.troja.mff.cuni.cz/~davidek/xorg/Xorg.0.log.i810driver
http://www-ucjf.troja.mff.cuni.cz/~davidek/xorg/xorg.conf

Can anyone of you navigate me please what to try to get more info or
maybe you already have some suggestion what to do ?

Thanks a lot,
best regards
Tomas
