  1. Stuck at 1024x768 with onboard i865g

    Hi there,

    my pc has a P5PE-VM ASUS motherboard with a 3 GHz Pentium 4, 1 GB RAM and
    an Intel 865G integrated graphic chip onboard running Debian testing.

    I'd like to connect this pc to a SONY KDL-32P2530 lcd tv via its pc
    (analog vga) input.

    The specifications of the tv say that its panel has a 1366x768
    resolution, but also that it can only accept a maximum of 1280x768@60 at
    its pc input...

    My problem is that I can't display neither 1366x768 nor 1280x768 with my
    xorg configuration (using the latest intel video driver coming in Debian
    testing). I've had no luck with the intel i810 driver of Debian stable
    neither.

    I've tried setting the correct resolution to the video bios with
    915resolutions, so that now I have:

    # 915resolution -l
    Intel 800/900 Series VBIOS Hack : version 0.5.3

    Chipset: 865G
    BIOS: TYPE 1
    Mode Table Offset: $C0000 + $269
    Mode Table Entries: 27

    Mode 30 : 640x480, 8 bits/pixel
    Mode 32 : 800x600, 8 bits/pixel
    Mode 34 : 1024x768, 8 bits/pixel
    Mode 38 : 1280x768, 24 bits/pixel
    Mode 3a : 1366x768, 24 bits/pixel
    Mode 3c : 1920x1440, 8 bits/pixel
    Mode 41 : 640x480, 16 bits/pixel
    Mode 43 : 800x600, 16 bits/pixel
    Mode 45 : 1024x768, 16 bits/pixel
    Mode 49 : 1280x768, 16 bits/pixel
    Mode 4b : 1366x768, 16 bits/pixel
    Mode 4d : 1920x1440, 16 bits/pixel
    Mode 50 : 640x480, 32 bits/pixel
    Mode 52 : 800x600, 32 bits/pixel
    Mode 54 : 1024x768, 32 bits/pixel
    Mode 58 : 1280x768, 32 bits/pixel
    Mode 5a : 1366x768, 32 bits/pixel
    Mode 5c : 1920x1440, 32 bits/pixel

    so 1280x768 as well as 1366x768 should be ok.

    I've tried many different modelines, but all I can see on my tv is a poor
    1024x768 which leaves two ugly black zones at each side of the screen.

    Here you can see my /etc/X11/xorg.conf:

    http://www.crazycoders.com/nopaste.php?nopaste=253

    and here you can see my /var/log/Xorg.0.log:

    http://www.crazycoders.com/nopaste.php?nopaste=255

    Now I'm thinking to insert a Nvidia GeForce card in the agp slot to solve
    the problem, but if possible I'd prefeer to use the onboard intel chip
    first because I have a 150 w power supply in my "media-center" case and
    one more card means more power to sink, and second (but not least)
    because Intel have open source drivers :-)

    Many thanks if someone could perhaps help me.

    I have a 82845G/GL[Brookdale-G]/GE/PE. I got stuck with the same res.
    While building the new Xorg and trying to get the intel drivers set
    nicely, I found that not setting modes at all made the best resolution
    automatically be selected. Do you have i2c support in this machine? Either
    in-kernel or as modules:

    i2c_i801 7568 0
    i2c_dev 7044 0

    I see in the config it's commented out, but it might be enabled by default
    because I see it mentioned in your log. Here's my intel-driver parts of my
    config:

    Section "Device"
    Identifier "Intel"
    Driver "i810"
    Option "DRI" "true"
    Option "XVideo" "true"
    Option "DDC" "true"
    EndSection


    That's the old i810 driver I rebuilt. My guess is Debian is using
    the new "intel" driver (see my post about xfr86-video-intel) but might
    have patched it. So on a system with the new driver, 'intel' is symlinked
    to by 'i810'.

    Section "Screen"
    Identifier "Intel.Screen"
    Device "Intel"
    Monitor "MAG Innovision"
    EndSection

    I never put modes anywhere. That, working with Mesa built as
    'linux-dri-xcb' with DRM support modules built from the kernel tree (not
    libdrm) gets me:

    which is the best I've seen this setup ever do. These are some the same

    572. (EE) intel(0): Unable to read from DVOI2C_E Slave 236.

    Other than trying to leave out the modelines, I'm not sure...

    Following your indications, I've loaded some i2c modules (some are needed
    by lm_sensors too):

    $ lsmod | grep i2c
    i2c_piix4 13836 0
    i2c_i801 13468 0
    i2c_i810 10632 0
    i2c_algo_bit 10884 1 i2c_i810
    i2c_isa 9344 1 w83627ehf
    i2c_dev 12424 0
    i2c_core 31488 7
    i2c_piix4,i2c_i801,i2c_i810,i2c_algo_bit,w83627ehf ,i2c_isa,i2c_dev

    Do you use 915resolution to set 1280x768?

    Can you also set 1360x768 (or 1366x768) too?

    I've also uncommented DDC and commented modelines as per this new /etc/
    X11/xorg.conf:

    http://www.crazycoders.com/nopaste.php?nopaste=265

    And this is its relevant /var/log/Xorg.o.log:

    > That's the old i810 driver I rebuilt.


    Do you think it's necessary to compile intel driver from sources?
    Generally, Debian packages are always fine...

    I've also tried some live distributions, Knoppix-5.1.1 and Knoppmyth, and
    they also set the screen at 1024x768.

    Perhaps I'll try rebuilding the driver too...
