Intel-Mobile 965 GM and LCD: black screen

English Hardware
1

Hi,

I installed openSUSE 11.0 on a barebone with Intel-Mobile Chipset 965 GM. My LCD is connected via DVI-Port, but it is possible to connect a monitor with a VGA-cable to the barebone DVI-Port using adapter DVI->VGA.

The configuration with Sax is possible, Sax says during test 1280x1024@60 but the test-card has only 1024x768@80 (monitor information). When starting the x-server after finishing sax the monitor says “out of range: vsync at 170 hz” and I got a black screen. :mad:

While Sax uses the “intel”-driver, I installed with sax2 -m 0=vesa the “vesa”-driver: everything worked fine, I got 1280x1024@60 but no 3D. Installing the old “i810”-driver did not work.

So, what can I do? I need 3D for Goole-Earth. :confused:

PS.: Later I installed (K)Ubuntu 8.4.1 with the same result (LCD with vsync 170) and I started Knoppix 5.3.1 from DVD also with the same result. A bug in the “intel”-driver?

have look here:

My barebone could not be found on this page!

4

the only other link I found was this
Patch the Video BIOS - openSUSE

I’m not even sure there is 3D support for these

Maybe someone with a Laptop with come in on this

Some useful Intel GMA config info in this Gentoo wiki:

Intel GMA - Gentoo Linux Wiki

915resolution has no effect! I will check the Gentoo Wiki.

It works!!! :slight_smile:

It is definitly a bug in the “Intel”-driver. The driver has problems with the DVI-I port (with both digital and anlalog signal). But there is a workaround available for the xorg.config:

Section "Monitor"
  Identifier   "Monitor[0]"
  ModelName    "VIEWSONIC VP191B"
  Option       "PreferredMode" "1280x1024"
  VendorName   "VIEWSONIC"
  VertRefresh  50-70
  UseModes     "Modes[0]"
EndSection

Section "Monitor"
  Identifier   "LVDS"
  Option       "Ignore" "true"
EndSection

Section "Device"
  BoardName    "965 GM"
  BusID        "0:2:0"
  Driver       "intel"
  Identifier   "Device[0]"
  Option       "monitor-VGA" "Monitor[0]"
  Option       "monitor-LVDS" "LVDS"
  VendorName   "Intel"
  Option       "ModeDebug"      "TRUE"
EndSection

You have to do the following: leave the normal monitor-section as it is. Then insert a second monitor-section as shown above and change the device-section as also shown above.

I got this solution via the xorg-mailing list (xorg Info Page)gegangen and I reported a bug at https://bugs.freedesktop.org.

Thanks a lot to Gordon Jin from Intel, who shows me this workaround.

Well done. Its always good to see solutions available for Intel shared graphics devices, given that they are commonly used in many laptops. :slight_smile:
