This reads to be a nice card. It should work in openSUSE-11.2 and it should not be necessary to reduce the memory from 4GB to 2GB to get it to work.
I have a laptop with an ATI Mobility Radeon HD3450 and with 4GB of RAM and I did not have to reduce memory to get it working with openSUSE-11.2 (albeit my Radeonhd card is a bit different).
I installed openSUSE-11.2 Linux on this laptop 2 weeks ago. I noticed some things that might be of interest. I originally had openSUSE-11.1 on this laptop with KDE4 and special desktop effects enabled with the proprietary ATI graphic driver. So when I installed openSUSE-11.2 on the laptop (keeping my previous /home ) the laptop froze when trying to boot KDE. This was because my previous settings in KDE4 (under openSUSE-11.1) using special desktop effects with the proprietary ATI graphic driver, were not compatible with KDE4 under openSUSE with the radeonhd graphic driver.
I discovered that by booting to run level 3 (full screen text mode), and using “yast” to create a new user, I was then able to boot to this new user. But as soon as “special desktop effects” were enabled in the new user account, KDE would freeze and no longer boot to the new user.
I solved this by installing the proprietary ATI graphic driver, and then both old and new user accounts worked ok with special desktop effects. It was NOT necessary to remove 2 GB of RAM.
So I recommend you do either one of two things. Either:
- update your open source radeonhd driver (that comes in the rpm xorg-x11-driver-video-radeonhd ) or
- install the proprietary ATI graphic driver
There are various guides on how to do this:
I also wrote a “practical theory guide” with post#1 explaining some basics: Post#1: openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums
… and post#11 in the same thread Post#11: openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums explaining how to install more cutting edge open source graphic drivers.
In my case, for my Radeon HD3450 I installed the proprietary ATI driver “the hardway” (which is not hard) as documented in this link ATI drivers - openSUSE that I also referenced above.
I wish you good luck in sorting this. Its actually very easy for an average openSUSE user who has been doing this for a while, but it can be daunting and frustrating for a new user.
If you stumble along the way, please post so some of our more knowledgeable forum users can try help you.
