Hmmm ....

Silly question ... what happens if you boot WITHOUT nomodeset, but
instead in the grub boot menu, remove the entry "vga=0xYYY" ?   There is
a bug report where that is a solution for some Intel integrated graphic
user on openSUSE-11.4, and I am curious if your hardware falls in that
category.

Post #67 in this thread was the relevant post:  'OpenSuse 11.4 startup

In that case, it appears the nominal "Intel" graphic driver is not
working for you (assuming that your install is good).  Along that lines
(is this a good install ) ? did you run an md5sum of the downloaded .iso
file and compare that to the md5sum on the download website ? Were they
they the same?   Assuming they were the same, did you burn the .iso file
to a dvd/cd at the slowest speed your burner allows to a +R or -R (and
NOT an RW) using high quality media and NOT some bargain basement
special ?  And did you run the media check option on the dvd/cd and have
it pass?

Assuming you did all that appropriately, then we know Intel graphic
driver is not working and FBDEV driver (which you get when you use the
boot code 'nomodeset') is working.  

You could try (1) vesa driver, or (2) intellegacy driver.  

I recommend you (having done the above cd/dvd quality checks) install
the application midnight commander (mc) if not already installed. You
may need that to do edits of text files in a text mode and 'mc' is VERY
user friendly.  With 'mc' installed you can launch it by typing 'mc' (no
quotes) and use the easy to follow Fx keys to navigate.

Then go ahead and edit the /etc/X11/xorg.conf.d/50-device.conf file
(with root permissions) , so as to have it load the intellegacy video
driver (which is in fact a very old version of the Intel graphic driver)
and see if that works better.  Assuming you have the rpm
xorg-x11-driver-video-intel-legacy installed, then the
/etc/X11/xorg.conf.d/50-device.conf file should look like (after your
edits with root permissions):

Code:
--------------------
    
  Section "Device"
  Identifier "Default Device"
  
  #Driver "radeon"
  *Driver "intellegacy"*
  
  ## Required magic for radeon/radeonhd drivers; output name
  ## (here: "DVI-0") can be figured out via 'xrandr -q'
  #Option "monitor-DVI-0" "Default Monitor"
  
  EndSection
  
  
--------------------
Note the line I added.

Then reboot and test.

If "intellegacy" does not work, then try "vesa" instead of
"intellegacy" in same file.

Note from command line one can restart the PC with:

Code:
--------------------
    shutdown -r now 
--------------------
and one can halt the PC with 

Code:
--------------------
    shutdown -h now 
--------------------
in both cases with root permissions.

A couple of more things that you may or may not know.

One can boot to a full screen text mode by pressing '3' (no quotes)
when the grub boot manager menu first appears, such that a '3' (no
quotes) appears in the options line with a space between it and any
other entries. That will boot the PC to a full screen text mode with no
gui. That can be useful at times.

(http://www.imagebam.com/image/2364eb129367620) 
-[click on image for larger view]-

Also there is a FailSafe mode which will use the boot code
'x11failsafe' (no quotes) which will also force the loading of the
'FBDEV' graphic driver which can be useful at times when all else fails.

You could write a bug report on this.

As an aside, did you confirm the quality of your installation CD/DVD
was good prior to installing ? ie run the md5sum against your downloaded
.iso file and confirm that the downloaded .iso file has the same md5sum
as that posted on the download web site?  Also burn to a +R or -R CD/DVD
(and not to an RW) at the slowest speed your burner allows to a high
quality media (and not some bargain basement special) ?  And finally did
you perform the 'mediacheck' on the installation CD/DVD to confirm it
passes ?

Ive tried both


Code:
--------------------
    
  Section "Device"
  Identifier "Default Device"
  
  #Driver "radeon"
  Driver "intellegacy"
  
  ## Required magic for radeon/radeonhd drivers; output name
  ## (here: "DVI-0") can be figured out via 'xrandr -q'
  #Option "monitor-DVI-0" "Default Monitor"
  
  EndSection
--------------------



Code:
--------------------
    
  Section "Device"
  Identifier "Default Device"
  
  #Driver "radeon"
  Driver "vesa"
  
  ## Required magic for radeon/radeonhd drivers; output name
  ## (here: "DVI-0") can be figured out via 'xrandr -q'
  #Option "monitor-DVI-0" "Default Monitor"
  
  EndSection
--------------------


This hasnt resolved the problem it still goes blank, only thing i have
noticed is when its saved as Intellegacy and run in nomodeset the
graphics are alot better

I note openSUSE-11.4 comes with the 2.14 Intel driver.  There is a 2.15
Intel driver available from Intel, but it has not been packaged yet for
openSUSE. At some point in the future it may be packaged for tumbleweed,
but its not there yet.  I note from the openSUSE weekly news an openSUSE
user has successfully installed the 2.15 driver, with a blog article
here: 'Ladislav's blog: Installing latest Intel graphics driver to
openSUSE 11.4' (http://tinyurl.com/3s25r45)  

That may or may not help. It may in fact make things worse forcing a
re-install. ... but then again, it may work. Its up to you to decide if
it worth following.  Note one needs a reasonable level of Linux
knowledge to follow that blog.

Edit - note there is an rpm available in the unstable X11 repos:

Code:
--------------------
    http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.4/
--------------------

Further to my note, I checked the change log for the
xorg-x11-driver-video rpm in that repos (after downloading but not
installing it):

Code:
--------------------
     rpm -qp xorg-x11-driver-video-7.6-206.5.x86_64.rpm --changelog 
--------------------
and noted:

Code:
--------------------
    
  * Fri Apr 15 2011 sndirsch@novell.com
  - disabled xf86-video-intel-copyfb.diff for now (bnc #687802)
  
  * Thu Apr 14 2011 sndirsch@novell.com
  - xf86-video-*intel 2.15.0*
  - obsoletes xf86-video-intel-uxa-Undo-damage-translation-before-appending.patch
  - adjusted xf86-video-intel-dell_backlight.diff,
  xf86-video-intel-copyfb.diff
  
--------------------


So it does have the Intel 2.15.0 version.

Trying to install that rpm may pull in dependencies that cause
problems. And it may not.  I simply do not know.

Yes there is. It requires a change to the /boot/grub/menu.lst file.
Post here the content of that file and I can point out the edit.

I am curious thou, is it the FBDEV driver that is being loaded with
this combination?  Can you paste the contents of your
/var/log/Xorg.0.log file to 'SUSE Paste' (http://susepaste.org) and the
post here the URL where that paste is located ?

With "intellegacy" driver correctly specified in
/etc/X11/xorg.conf.d/50-device.conf, you shouldn't need "nomodeset" as
the older "intellegacy" doesn't do KMS.

@AndrewJBarratt, try it for yourself without "nomodeset".

it doesnt matter which driver i have specified in the .conf it still
turns the screen off without "nomodeset"

i accidentally booted today without "nomodeset" and have discovered the
screen isnt actually off, its just that dark that it appears that its
off, i can faintly in the background see the desktop

i thought that aswell!

As i said previously when "intellegacy" is saved in the 50-device.conf
file and i use "nomodeset" the graphics are quite smooth

If i remove "intellegacy" from the 50-device.conf and use "nomodeset"
graphics are rough and it uses a rubbish resolution

Interesting ... I see many " (II) intellegacy(0) " entries, which says
to me that even though the 'nomodeset' boot code is specified, as long
as "intellegacy" is specified in the 50-device.conf file, then the
intellegacy (old intel version) driver is loaded and not the FBDEV
driver.

That is a very important detail, you know. It might just be that the
backlight is off.

My laptop also has a GM45 chipset and works fine without doing anything.

To be expected, since "nomodeset" doesn't actually load a driver. The
"intel" driver cannot load without KMS support, so "fbdev" loads by
default. If you specify "intellegacy" (KMS not required) it will load
whether or not you specify "nomodeset".

Yes that was also my understanding.  However in another thread (or was
it on IRC chat ? - my memory fails me) I had someone claim to me that
they applied 'intellegacy' and obtained 'fbdev' (to which I was
skeptical), and so I wanted to confirm with someone else that indeed
what I thought was the case, was indeed the case.

Backlight has been mentioned above, what would cause the back light not

Back after reboot and should be on the updated driver, having survived
:). I'm on KDE so not noticing much difference as I had no problem on
this system.

Looking forward to seeing if the update fixed an issue I had on Gnome
with desktop effects enabled where the cursor locks up/disappears in
browser while posting in this forum. It claims to have fixed issues with
compositing and using some editors. I wonder if it fixed another problem
with latest Flash updates and KDE power management interference on
full-screen... Anyway, sorry that's all a bit off topic. :)

I think backlight is controlled through the acpi -video- module, but
some laptops need a vendor-specific acpi driver. Anyway a bug report may
be needed to get it fixed, and a careful search to see if it has already
been reported.

Your laptop may have special backlight control keys. If so you could try
to increase the level, although that may not work in the circumstances.
If you can see anything on the dimmed diisplay, you could enter the
command -xbacklight- in a terminal/console. Without entering options, it
should return a percentage figure - probably very low in your case. Here
is the help reported, in case you are able to try to adjust the
backlight:

Code:
--------------------
    >xbacklight --help
  usage: xbacklight [options]
  where options are:
  -display <display> or -d <display>
  -help
  -set <percentage> or = <percentage>
  -inc <percentage> or + <percentage>
  -dec <percentage> or - <percentage>
  -get
  -time <fade time in milliseconds>
  -steps <number of steps in fade>
--------------------

Take a look at this older post: 'Booting in generic no backlight, boot
in failsafe backlight is on' (http://tinyurl.com/42lcvzz). That may
explain why "nomodeset" works as fbdev usually only gives resolution
1024x768.

And take a look at the last post(s) #9 in 'this older thread'
(http://tinyurl.com/3b7xf8u).

Both mention acer machines.

For information, I note this in the change history:

Code:
--------------------
    
  Distribution: openSUSE 11.4
  * Fri Apr 15 2011 sndirsch-at-novell.com
  - xf86-video-intel-gen6-Invalidate-texture-cache.patch
  * fixes partial screen distortion on Sandybridge visible in KDE
  (bnc #680921, bfo #35808)
  
  * Wed Apr 13 2011 James.Bottomley-at-suse.de
  - xf86-video-intel-damage-fix.diff
  * upstream commit da990536eca09c6de74627541cd56ecfad925eda
  uxa: Undo damage translation before appending
  * our bugzilla 666704
  * freedesktop bugzilla https://bugs.freedesktop.org/show_bug.cgi?id=32734
  
--------------------
Bug 32374 is for corrupted windows with Intel hardware.  Bugzilla 666704
is the same bug.

In both cases the patches appear to be for Intel hardware.
