Black screen after install (opensuse11)

I’ve just installed suse on my laptop, didnt change anything from the default in the installer other than selecting gnome and putting in my username/password.

The install finished fine, as did the auto config thing, it boots to grub fine but when I select the normal opensuse11 boot option it runs through a bunch of text then I get a black screen. When I hit ctrl+alt+backspace I can see an error - something about the monitor not being supported. When I login and try startx it just says x is already running on monitor0

Anyone know what’s wrong? I had a similar problem using the dreamlinux live cd, but the fix for that dosnt seem to be working for me here (it was something along the lines of ‘dkpg-reconfigure xserver-xorg’ then I could set my graphics card resolution and refresh manually). I also tried a ubuntu live cd and it boots just fine.

The laptop is a Dell Studio 1535, graphics card is an ATI Radeon Mobility HD 3400.

I would try copying over the monitor info from the Ubuntu LiveCD to the xorg.conf file on your openSUSE installation.

I also have the same problem.
Please help!
What should we do to make screen working in the normal mode?

At the boot menu, type the number 3 in the data entry bar below. This will take you to a command prompt; login. Then

su

which will switch you to root privilege. Then do


sax2 -r -a

Configure the card and the monitor. If the graphics configuration gui did not come up, then try

sax2 -r -m 0=radeon

Failing that, then

sax2 -r -m 0=vesa

Report back. The radeon driver above is an open-source driver for ATI graphics devices, but it does not support all of them nor does it support 3D acceleration. You will probably want to install the ATI proprietary driver (fglrx). The above hopefully gets you into the gui where installing fglrx is easier to do. But if none of the above works, fglrx can also be installed from the command line.

It is also possible that it is the monitor configuration itself that is the problem. The above commands may give you the opportunity to correct that.

By the way, “dkpg-reconfigure xserver-xorg” is the (less capable) Debian alternative to openSUSE’s sax2. And the reason why you get the gui in a Live-CD is that it is using a generic “framebuffer” driver rather than the X Server driver specific for your graphics device; the former provides the basic functionality needed to install or demo, but not the full functionality of the latter.
