intel 945 graphics and 1280x1024 resolution


Hi,

recently I upgraded my box with intel 945GZ graphics to 1280x1024 monitor. However, X often refuses to bring up this mode and resets to 640x480(!).

lspci gives

Code:
00:02.0 VGA compatible controller: Intel Corporation 945G/GZ Express Integrated Graphics Controller (rev 02)
I have i810 driver for the Xorg and i915 for the kernel. This is debian etch, kernel 2.6.18-5-686 #1 SMP

When X brings up the wrong resolution it complains as this in the log:

Code:
(II) I810(0): VESA VBE DDC read failed
and later:

Code:
(II) I810(0): Not using mode "1280x1024" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (640 -> 1024).
(--) I810(0): Virtual size is 640x480 (pitch 1024)
(**) I810(0):  Built-in mode "640x480"
If it works, one can see instead:

The modeline is compiled using the X log lines:

Code:
(II) I810(0): Supported additional Video Mode:
(II) I810(0): clock: 108.0 MHz   Image Size:  376 x 301 mm
(II) I810(0): h_active: 1280  h_sync: 1328  h_sync_end 1440 h_blank_end 1688 h_border: 0
(II) I810(0): v_active: 1024  v_sync: 1025  v_sync_end 1028 v_blanking: 1066 v_border: 0
Any ideas? What is VESA VBE DDC?

Best,
Ott

Hello otoomet,

I also have a 945GZ chipset with a 1024x1280 monitor and i also use Debian Etch. I toke note of my configuration on my website. Please try to follow the instructions, it also explains how to enable copmiz.

I did the reconfigure but it did not help.

915resolution does not seem to help either. I installed it, exactly as in your example. It seems to be working (claims that "Patch mode 58 to resolution 1280x1024 complete" when run manually), but I cannot understand whether it in fact is run during startup. There seems to be no traces of it in logs. The aiglx stuff is not related to 915resolution?

Hello otoomet,

Sorry for the waiting, but i was busy. I think it will be the best if i send you my config files. You need 915resolution to take more shared memory for your graphics card.

/etc/default/915resolution

#
# 915resolution default
#
# find free modes by /usr/sbin/915resolution -l
# and set it to MODE or set to 'MODE=auto'
#
# With 'auto' detection, the panel-size will be fetched from the VBE
# BIOS if possible and the highest-numbered mode in each bit-depth
# will be overwritten with the detected panel-size.
MODE=58
#
# and set resolutions for the mode.
# e.g. use XRESO=1024 and YRESO=768
XRESO=1280
YRESO=1024
#
# We can also set the pixel mode.
# e.g. use BIT=32
# Please note that this is optional,
# you can also leave this value blank.
BIT=32

/etc/X11/xorg.conf

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

I hope this can help you, it should do the trick because i am working with these config files. Attention: the keybord is set to Belgium because i live there.

Hmmm... I don't see any difference here... I tried some small modifications, like modeline and fbdevice, but those did not matter. Also, 915resolution seems not to matter, it just killed the display if I switched it on while thawing from hibernate.

Is it possible that the monitor is somehow "incompatible" with the graphics card/driver?

As I mentioned, it works often, but not always. If not, I press C-A-backspace until it works.

Thanks a lot,
Ott

I upgraded to lenny with 'intel' driver instead of 'i810'. It works perfectly now. Would be nice to know whether the problem was driver, xorg, kernel or something else.

The new Intel driver doesn't need 915resolution any more to have higher resolutions. So the new driver is better and this is the reason why it works fine.

Best regards,
