Description Warren Togami 2007-03-01 05:04:14 UTC
Dell Latitude D620 with A07 BIOS.
Intel 945 video
1440x900 screen

X fails to start with both intel and i810 drivers in RHEL5 and FC7 test2.  ajax
said that this is some kind of BIOS problem.  Details attached next.

Comment 3 Warren Togami 2007-03-02 00:47:32 UTC
It appears that unlike other laptops, it isn't happy working at even 1024x768
out of the box.  X starts, but it displays garbage on the screen.

If you rewrite a BIOS mode to 1440x900, use i810 instead of intel, and hard-code
it to xorg.conf, then X works.

Mode setting driver that elminates the need for 915resolution is supposed to hit
rawhide soon?

Is it reasonable to close this bug only if auto-configuration sets up the screen
to work properly without hard-coding and without 915resolution?

Comment 4 Warren Togami 2007-03-02 00:50:08 UTC
Also, is it reasonable to rev a future version of this BIOS so the machine knows
the actual resolution of its own screen?

Comment 5 Matěj Cepl 2007-03-02 17:52:50 UTC
Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) to the bug report
as individual uncompressed file attachment using the bugzilla file attachment
link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Tim Reilly is the new user of this particular laptop, so he is responsible for
testing and providing this information.

Comment 9 Tim Reilly 2007-03-06 22:45:21 UTC
I provided the requested files. I'm not as technical a user as Warren so I can
only guess that I provided the files using the right system setup. I provided
these files with the 915resolution software running. 

Also, in between Warren handing this laptop off to me and me posting these
files, I updated some X packages along with usual rawhide updates. This may have
impacted the bug. I'm not yet fully immersed in the issues related to this bug.

I like this laptop a great deal and hope to provide any addition info you might

Comment 10 Adam Jackson 2007-03-06 23:12:13 UTC
Tim, that looks suspiciously like a successful X startup.  I am confuzzled.

Also there's been a fairly major update to the X server and intel drivers in the
last few days, so this might magically start working.  Feel free to bring the
laptop by if you're in the office.

Comment 11 Warren Togami 2007-03-06 23:18:37 UTC
He is running it after 915resolution rewrote a BIOS mode.

Tim Reilly,

1) Disable the 915resolution service. 
   chkconfig 915resolution off
2) Reboot into runlevel 3 instead of 5.  (text boot with network)
   At the grub screen, hit "e", add "3" to the end of the second line, and "b"
to boot.
3) Login as root
4) Remove xorg.conf and see if Xorg works at all.

Comment 12 Adam Jackson 2007-03-07 16:32:42 UTC
915resolution wildly unsupported blah blah blah.

Seriously, try rawhide and the intel driver, without using 915resolution.  Ought
to work pretty reasonably.

Comment 13 Tim Reilly 2007-03-14 18:26:17 UTC
I talked to ajax about this but didn't update the bug. It fails to start without

Comment 14 Bernd Bartmann 2007-03-31 18:53:35 UTC
Still lots of problems with the i810 and intel driver in FC7T3 on my DELL D620

1. FC7T3 creates an xorg.conf file using the i810 driver by default. This is
result is no display output on the laptop display when the system is undocked.

2. When the laptop is docked I shut down the lid and have an external 20" DELL
TFT attached. This seems to work. I get a screen output with the correct
resolution (1600x1200) but the timing is not entirely correct. Sometimes I see
flickering lines and sometimes the display goes into power down mode and tells
me that I should use correct timings for the 1600x1200 resolution.

3. When the laptop is undocked and I try the intel driver I see the backlight
going on but the display remains black.

4. When the laptop is docked and I try the intel driver I see a standard X11
background (the black / white checker board) come up. The resolution only looks
like 800x600 and I can't switch back to the text console.

I'll attach the Xorg logs.

Comment 20 Jeremy Katz 2007-04-19 00:07:03 UTC
We should be switched to the intel driver by default for this chipset now.  Do
things work better with current rawhide/test4?

Comment 21 Gideon de Kok 2007-04-21 17:18:04 UTC
The "i810 1440x900" problem can be fixed by manually setting the v/hsync for the

      HorizSync 30-80
      VertRefresh 60-70

This should be auto detected though...

Comment 22 Tim Reilly 2007-05-02 22:03:39 UTC
Package updates weren't fixing it on my old install, but with a fresh test4
install things worked perfectly!

Comment 23 Kevin Fenzi 2007-05-08 05:18:55 UTC
FWIW, my D820 works great with the current rawide/devel "intel" driver. 
With fc6 and the i810 driver I had to use 915Resolution to get the right
resolution, but the current "intel" driver just does the right thing out of the

So, can we close this bug now? 

Bernd? Does it now work for you with the current intel driver? 

Comment 24 Bernd Bartmann 2007-05-08 15:42:21 UTC
For me also everything looks good now with FC7T4.

Comment 25 Kevin Fenzi 2007-05-08 15:58:34 UTC
ok, Sounds like it works for everyone, I will go ahead and close this...
