Upgrade from 9.04 to 9.10 only displays in 800x600 on Intel 82G35 display controller

[Alex Janssen]

"X -configure" produces a xorg.conf file that shows my display
controller properly, but it runs the display in 800x600.  The only
options in System->Preferences->Display are 800x600 and 640x480 and it
does not recognize the monitor, a Viewsonic AW1703wb that should be run
at 1440x900.  I have tried reinstalling the xserver, but no better.
I can not find any bugs reported spcifically for this issue.
U9.04 had no problems with this board or monitor.
Should I reinstall 9.04 and wait a couple of months or is there a fix?
I could try a fresh install as /home is on a different partition from /.

Your xorg.conf may not accurately reflect your video card/monitor capabilities. Here is the 24 bit mode section for my xorg.conf.  You can use that as a template if you want to try modifying yours manually. Sounds like it may be your only option. Goes without saying that you should remove any options that do not fit your hardware's capabilities.

    SubSection     "Display"
        Depth       24
        Modes      "1920x1200" "1600x1200" "1600x1024" "1600x1000" "1400x1050" "1600x900" "1280x1024" "1440x900" "1280x960" "1366x768" "1360x768" "1280x800" "1152x864" "1280x768" "1280x720" "1024x768" "1280x600" "1024x600" "800x600" "768x576" "640x480"
    EndSubSection

Hope that works for you. For some reason the video config programs are very buggy. I always have to tweak it manually. That is bad for newbies that are new to linux.

Regards,

john

Alas.  No joy, yet.  I burned the iso to a cd and booted it.  Same
results. 800x600.  I filed a bug(#469764) on Launchpad.  Reinstalled
9.04 with no problems.  I don't know enough to dig into the code for the
Intel driver.

Thanks
Alex

Here's the answer in case anyone else needs it.
Go to http://wiki.ubuntu.com/X/Troubleshooting.
All the info you need is there.  Read it.
After that I manually constructed the following xorg.conf:
*** xorg.conf ***
Section "Monitor"
    Identifier   "Monitor0"
    VendorName   "Viewsonic"
    ModelName    "VA1703wb"
    HorizSync    24.0 - 70.0
    VertRefresh  50.0 - 75.0
    DisplaySize  365 228
EndSection

Section "Device"
  Option     "NoDDC" "true"
    Option "IgnoreEDID" "true"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "82G35 Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Card0"
    Monitor    "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
        Modes      "1440x900" "1360x768" "1152x864" "1024x768" "800x600"
"640x480"
    EndSubSection
EndSection

I don't want to start a flame war.  Just noting this.  I would have to
say this is not for the casual computer user, like my wife(and many
others).  If it doesn't work, she says "why can't I just use Windows?",
so I go fix it for her.  Another reason why Windows will remain the
desktop king(but not in this crowd).  We work together and I make her
use Ubuntu for her job.  She hasn't used windows for 2 years, now.

Of course what she means is why can't I go buy a pre-configured systems rather
than wing it and be in front of the curve. I suspect there are plenty of
people upgrading to Windows 7 themselves and *something* didn't go right with
a driver.

That being said, I don't understand all the regression issues with Intel
chipsets. The madness started with 8.10 (at least for me). I was hoping 9.10
would be the light at the end of the tunnel. (I am dutifully waiting for others
to shake it down.)
